With continued reference to FIG. 4, a logic diagram of the present embodiment for determining the pitch of the woven fibers of the natural material is shown;
Specifically, in step S3, a standard color value and a standard color fluctuation difference value of the flame retardant liquid are set, and a determination range is formed according to the standard color value and the standard color fluctuation difference value;
In step S3, the real-time image of the web substrate 105 acquired by the first recognition judging device 2 is divided into a plurality of areas, the color values of each pixel point in any one of the areas are acquired, the average value of the color values of each pixel point in the area is calculated as the mark color value of the area,
The mark color values of each partition in the real-time image of the webbing base 105 are respectively subjected to determination marking according to the determination range formed by the standard color value and the standard color fluctuation difference value,
If the marking color value of any partition is within the judging range, marking the partition as an attaching area;
if the marking color value of any partition is not in the judging range, the partition is not marked.
By dividing each pixel point in the image acquisition into a plurality of judging areas and comparing the marking color values of the pixel points in each judging area with the calculated judging ranges, the real-time attachment degree of the flame retardant liquid at the woven belt substrate 105 is imaged so as to be convenient for judging and comparing, and the real-time attachment rate Fs between the flame retardant liquid and the woven belt substrate 105 is convenient for subsequent calculation.
In this embodiment, the standard color value of the set flame retardant liquid should be selected according to the type of the flame retardant liquid actually used or the color of the added dye, for example, when the red dye is used to dye the flame retardant liquid to help to distinguish it, if the rgb value of the color of the flame retardant liquid is (240,30,30), the color value is calculated to be 240+30+30=300, i.e. in this embodiment, the value 300 is used as the standard color value of the flame retardant liquid, wherein the standard color fluctuation difference is affected by factors such as site illumination and dyeing impurities, so that the standard color fluctuation difference should be set selectively according to the production scene in the actual production process, which is not repeated here, but generally the standard color fluctuation difference should not be greater than 30.
Specifically, in step S3, the total area of the real-time image of the webbing base 105 is obtained by the first recognition determination device 2, the total area of all the areas with the attachment area mark partitions in the real-time image is obtained according to the partition mark result of the real-time image, and the real-time attachment rate of the current webbing base 105 is calculated according to the total area of the real-time image and the total area of all the areas with the attachment area mark partitions;
Where fs=s1/S, fs is the real-time adhesion rate, S1 is the total area of all the marked partitions with the adhesion area in the real-time image, and S is the total area of the real-time image.
In this embodiment, the image division adopts an equal area division manner, the number of image areas can directly affect the real-time attachment rate calculation accuracy, the real-time attachment rate calculation accuracy can be improved by using a manner of dividing more areas, and in actual use, corresponding division setting is required to be performed by combining with the calculation capability of the image processing device, and the number of the divided areas is generally not less than 100;
For example, when the acquired image area is divided into N image determination areas, and the acquired area of each image determination area is a, the total area s=n×a of the real-time image, and Nf total areas of the attachment area mark areas in the real-time image, the total area s1=nf×a of all the attachment area mark areas in the real-time image, that is, the real-time attachment ratio fs= (nf×a)/(n×a).
Specifically, in step S3, a standard attachment rate is also provided, and when the first recognition judgment means 2 has calculated the real-time attachment rate, the real-time attachment rate is compared with the standard attachment rate,
If the real-time attachment rate is smaller than the standard attachment rate, the weaving pitch in the step S1 is adjusted according to the real-time attachment rate and the standard attachment rate;
if the real-time adhesion rate is equal to or higher than the standard adhesion rate, the comparison is made without adjusting the knitting pitch in step S1.
By comparing the calculated real-time adhesion rate with the standard adhesion rate, the degree of dip-dyeing of the current webbing base 105 is determined, that is, when the real-time adhesion rate is smaller than the standard adhesion rate, the degree of dip-dyeing of the current webbing base 105 does not meet the required dip-dyeing standard, and therefore, correction is required, that is, the interfacial adhesion between the surface of the webbing base 105 and the flame retardant liquid is insufficient, and therefore, the pitch between the natural material fibers 102 wound on the surface is required to be reduced, so that the coverage rate of the natural material fibers 101 is increased, and the purpose of increasing the surface adhesion of the subsequent webbing base 105 is achieved.
Specifically, when the real-time attachment rate of the webbing base 105 is smaller than the standard attachment rate, the weaving pitch parameter of the natural material fiber 102 in step S1 is acquired, and the weaving pitch parameter of the natural material fiber 102 is corrected according to the real-time attachment rate and the standard attachment rate;
wherein Q '=q× [1+ (Fb-Fs)/Fb ], Q' is the braiding pitch of the natural material fiber 102 after correction, Q is the braiding pitch of the natural material fiber 102 in the current braiding process, fb is the set standard attachment rate, and Fs is the real-time attachment rate.
In this embodiment, the weaving pitch and standard attachment rate of the natural material fiber 102 are selected according to the material of the natural material fiber 102 and the flame retardant effect of the required flame retardant webbing, and the weaving pitch and standard attachment rate of the webbing with flame retardant requirement are set in combination with the actual production process mode, generally, the standard attachment rate of the webbing with flame retardant requirement is not lower than 0.96.
The description will not be repeated here, and the actual operation of the implementation personnel will not be affected.
And when the calculated real-time adhesion rate is smaller than the standard adhesion rate, the first recognition procedure judges that the current woven belt substrate 105 needs to be coated for the first time, and the first coating procedure is used for coating and correcting the woven belt substrate 105 which needs to be coated after the judgment, namely, when the first recognition procedure judges that the real-time adhesion rate of the current woven belt substrate 105 is smaller than the standard adhesion rate, the dip dyeing degree of the current woven belt substrate 105 cannot meet the required flame retardant effect, so that the first coating device is required to carry out compensation and correction on the dip dyed woven belt substrate 105, and the woven belt substrate 105 which does not reach the dip dyeing standard is prevented from flowing to the next procedure.
Specifically, in step S6, a current color fluctuation difference value for judging the current color value of the webbing base 105 is set, the standard color value of the natural material fiber 102 and the standard color value of the flame retardant material fiber 101 are obtained, the range of the naked leak color of the natural material fiber 102 and the range of the naked leak color of the flame retardant material fiber 101 are calculated according to the standard color value of the natural material fiber 102 and the standard color value of the flame retardant material fiber 101 respectively,
Wherein yb1=yb- Δy, yb2=yb+Δy, ya1=ya- Δy, ya2=ya+Δy, yb is the standard color value of the natural material fiber 102, ya is the standard color value of the flame retardant material fiber 101, Δy is the current color fluctuation difference, yb1 is the minimum value of the bare color range of the natural material fiber 102, yb2 is the maximum value of the bare color range of the natural material fiber 102, ya1 is the minimum value of the bare color range of the flame retardant material fiber 101, ya2 is the maximum value of the bare color range of the flame retardant material fiber 101;
The woven belt substrate 105 is subjected to secondary real-time image acquisition through the second identification and judgment device 5, real-time color values of the secondary real-time images are extracted, the image area of the real-time color values in the secondary real-time images within the range of the naked eye color of the natural material fiber 102 is determined to be used as a first naked eye area, the image area of the real-time color values within the range of the naked eye color of the flame retardant material fiber 101 is determined to be used as a second naked eye area, and the real-time naked eye rate is calculated according to the acquired total image area of the secondary real-time images;
wherein ls= (s1+s2)/Sz, S1 is a first bare drain area, S2 is a second bare drain area, sz is an image total area of the secondary real-time image, and Ls is a real-time bare drain rate;
comparing the real-time bare leak rate with the standard bare leak rate,
If the real-time bare leak rate is greater than the standard bare leak rate, judging that the woven belt substrate 105 at the current position has defects, and adjusting the real-time drying wind speed in the step S5 according to the real-time bare leak rate and the standard bare leak rate;
when the real-time bare leak rate is smaller than or equal to the standard bare leak rate, it is determined that the woven belt substrate 105 at the current position has no defect, and the drying wind speed in step S5 is not required to be adjusted.
In this embodiment, the standard color value Yb of the natural material fiber 102 and the standard color value Ya of the flame retardant material fiber 101 are both selected according to the own color of the material, for example, if a white cotton yarn with an own color rgb value of (250,200,200) is used as the natural material fiber 102 and a black flame retardant polyester with an own color rgb value of (10,10,10) is used as the flame retardant material fiber 101, the standard color value yb=250+200+200=650 of the natural material fiber 102 is calculated, the standard color value ya=10+10+10=30 of the flame retardant material fiber 101 is calculated, the value of the color difference Δy is determined according to the own color of the selected material, and a large error may exist in the Δy of the color difference due to the own color of the material, but generally the Δy of the color difference is determined to be not greater than 50.
Specifically, when the real-time bare leak rate of the webbing base 105 is greater than the standard bare leak rate, the drying wind speed parameter of the first drying device 4 in step S5 is acquired, and the drying wind speed parameter of the first drying device 4 is corrected according to the real-time bare leak rate and the standard bare leak rate;
wherein V '=v× (Lb/Ls), V' is the corrected drying wind speed of the first drying device 4, V is the obtained current drying wind speed of the first drying device 4, lb is the set standard bare leak rate, and Ls is the real-time bare leak rate.
By comparing the calculated real-time bare leak rate with the standard bare leak rate, the second identifying device 5 can determine the coverage degree of the flame retardant liquid on the current webbing base 105, that is, when the real-time bare leak rate is greater than the standard bare leak rate, the coverage degree of the flame retardant liquid on the surface of the webbing base 105 after drying cannot reach the required standard, the surface of the webbing base 105 has bare leak condition, and the situation of coating and correcting the same is required, that is, the drying wind speed in the current second drying device may have too high wind speed, so that the drying speed of the flame retardant liquid on the surface of the webbing base 105 is too high, and the situation of broken bare leak occurs, therefore, the real-time drying wind speed in the first drying device 4 needs to be reduced, and the drying speed is more uniform.
However, the drying air speed in the first drying device 4 should be set to a minimum air speed value, when the real-time drying air speed of the first drying device 4 is lower than the minimum air speed value, an alarm is given to avoid the situation that the fire-retardant liquid at the braid substrate 105 fails to be dried normally due to the too low air speed, and the minimum air speed value should be set in combination with the actual production process mode, and generally, the minimum drying air speed value should not be lower than 1 m/s.
Specifically, in step S9, real-time determination is performed according to the real-time webbing meter weight detected by the set standard webbing meter weight symmetric weighing device, if the real-time webbing meter weight detected by the weighing device is greater than the standard webbing meter weight, it is determined that the current flame-retardant webbing has defects in its own weight, and the participation amount of the natural material fibers 102 in step S1 is adjusted according to the real-time webbing meter weight and the standard webbing meter weight;
Wherein N '=n-n× (Gs-Gb)/Gb, N' is the number of participation of the modified natural material fibers 102, N is the preset number of participation of the natural material fibers 102, gb is the set standard webbing weight per meter, gs is the real-time webbing weight per meter, and when n× (Gs-Gb)/Gb is less than 1, automatic correction is 1;
If the real-time webbing weight is smaller than or equal to the standard webbing weight, judging that the current flame-retardant webbing weight is normal, and introducing the output end of the current flame-retardant webbing into a winding packaging device for packaging output;
Wherein N '=n-n× (Gs-Gb)/Gb, N' is the number of participation of the modified natural material fibers 102, N is the preset number of participation of the natural material fibers 102, gb is the set standard webbing weight per meter, gs is the real-time webbing weight per meter, and when n× (Gs-Gb)/Gb is less than 1, automatic correction is 1.
The real-time weight bearing is carried out on the to-be-output flame-retardant braid through the weighing device, the real-time braid meter weight of the braided braid is obtained, when the real-time braid meter weight exceeds the standard braid meter weight, the surface of the braided braid can reach the required adhesive force under the current braiding pitch parameter, and meanwhile, the number of the involved natural material fibers 102 is excessive, so that the real-time braid meter weight is excessively high, and at the moment, the real-time braid meter weight can be adjusted by reducing the participation number of the natural material fibers 102, so that the final finished product weight of the braided braid is reduced, and the braided braid is more convenient to use.
Meanwhile, in order to avoid that the participation amount of the natural material fiber 102 is too low, since a minimum participation amount is preset, the minimum participation amount is set to be 1 in the embodiment, and an alarm is given when the participation amount of the natural material fiber 102 is less than or equal to 1.
The standard webbing weight in the embodiment should be preset according to the application scenario of the required flame-retardant webbing, and the weighing mode of the actual weighing device needs to be selected, because the flame-retardant webbing in the embodiment is produced in real time, the weighing device needs to carry out weighing calculation on a part of the flame-retardant webbing under the condition that the real-time webbing is not cut, slight errors can be generated, the standard webbing weight in the actual production needs to be judged by combining the size parameters of the real-time webbing, the calculation unit of the standard webbing weight is gram/meter, and the rest modes are not described too much, and do not affect the actual operation of the person skilled in the art.
