The technical scheme is basically that the soft air pipe is limited by the diameter adjusting component to enable the surface of the soft air pipe to be kept in an extending state, namely, the surface of the soft air pipe is basically free of wrinkles, the processing positioning is facilitated to be improved, the wire feeding component and the wire discharging component convey steel wires to the surface of the soft air pipe, meanwhile, the rubber strips are conveyed to the upper side of the steel wires by the pressing wheel 850, then the welding gun 900 melts the welding wires between the rubber strips and the surface of the soft air pipe, the steel wires can be fixed on the surface of the soft air pipe, and the steel wires which are spirally fixed on the surface of the soft air pipe are finally obtained along with the continuous rotation of the soft air pipe driven by the transmission component. The strength of the soft air pipe is improved as a whole, and compared with the mode that steel wires are added to the soft air pipe one by one manually in the prior art, the automatic air pipe production line can improve the automation degree and the production efficiency.
In the embodiment of the present application including the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, for simplifying the structure, in the embodiment shown in fig. 1-6, the second tensioning assembly and the third tensioning assembly are respectively arranged at two sides of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly respectively respond to the driving of the second cylinder and the third cylinder to slide along the inclined hole 510, and the size of the soft air duct which can be opened by the first tensioning assembly, the second tensioning assembly and the third tensioning assembly and the extent of tensioning the soft air duct can be adjusted by adjusting the distance between the second tensioning assembly and the third tensioning assembly relative to the first tensioning assembly.
According to the technical scheme, the soft air pipe is driven by the rotating component to continuously rotate along the circumferential direction of the soft air pipe, and the steel wire is spirally welded on the surface of the soft air pipe by moving on the axis of the soft air pipe, so that the soft air pipe can be manually pulled to translate or the welding gun 900 can translate. In the embodiment shown in fig. 1-3, the application further comprises a guide wheel for being in compression connection with the outside of the soft air pipe and a limit head 830 for guiding the steel wire towards the welding gun 900, wherein the guide wheel has a tangential force towards one side angle to apply force to the soft air pipe so as to enable the soft air pipe to translate, the limit head 830 is mainly used for limiting the trend of the steel wire and enabling the steel wire to be introduced into a gap between the adhesive tape and the soft air pipe so as to facilitate the subsequent welding and fixing work, and meanwhile, the position selection of the limit head 830 also has a limiting effect on the pitch of the spiral steel wire, and the distance between the limit head 830 and the welding gun 900 indirectly limits the tightness of the spiral of the steel wire on the soft air pipe.
The first tensioning assembly, the second tensioning assembly and the third tensioning assembly can be integrated components or split components, and in the aspect of the construction of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, the application at least comprises two embodiments, namely, firstly, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are integrated, a soft air pipe is sleeved on the first tensioning assembly, the second tensioning assembly and the third tensioning assembly when the soft air pipe is processed, then the soft air pipe is subjected to subsequent operation, secondly, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are split, and only the soft air pipe is required to be installed on one side from a gap between the second tensioning assembly and the third tensioning assembly when the soft air pipe is processed, and the embodiment is provided with an external processing part at a position outside the gap, so that the soft air pipe arranged at the gap position when the soft air pipe is processed can be well distinguished from a part which is not processed.
As shown in fig. 1-6, in the latter embodiment of the front section, the stand is also provided in a split type, specifically including a finished side frame body 541 and a machined side frame body 542, and corresponding finished side frame body 541 and machined side frame body 542 are both provided with inclined holes 510. The first tensioning assembly, the second tensioning assembly and the third tensioning assembly may be split in a manner that the first tensioning assembly includes a first arm 611 and a second arm 621 mounted on the working side frame body 542 and the finished side frame body 541, respectively, the second tensioning assembly includes a third arm 641 and a fourth arm 642 mounted on the working side frame body 542 and the finished side frame body 541, respectively, and the third tensioning assembly includes a fifth arm 661 and a sixth arm 662 mounted on the working side frame body 542 and the finished side frame body 541, respectively. In order to facilitate installation of the soft air duct, the present application preferably provides that either the finished side frame body 541 or the machined side frame body 542 be removable, such as by sliding connection with an external frame body or by mounting rollers, to allow for additional space for the soft air duct to fit in prior to machining.
On the basis of the above embodiment, in order to perform consistent and accurate processing on the soft air duct translated to the position outside the gap, it is preferable that the ends of the first support arm 611 and the second support arm 621 are sleeved with each other, as shown in fig. 1-4, on one hand, support is provided for processing the soft air duct in the gap portion, collapse and wrinkling are avoided due to softer soft air duct materials, so that the processing and positioning are facilitated, and on the other hand, the sleeved mode is also convenient for separating and loading the soft air duct into the soft air duct for processing.
In addition, in some embodiments of the present invention, as shown in fig. 3, 4 and 6, the diameter adjustment assembly further includes a supporting block 680 mounted on the processing side frame 542, the intersecting lines of the first arm 611, the third arm 641 and the fifth arm 661 with the soft air duct are all located on the same virtual cylindrical surface, and the supporting block 680 has a bearing surface 681 located on the cylindrical surface, preferably the bearing surface 681 is disposed in the gap area, so as to support the soft air duct conveyed to the location, thereby facilitating processing positioning.
The technical scheme of the application is suitable for the condition that radial processing is required to be carried out on the soft air pipe, and can be used for processing for adjusting the local strength of the soft air pipe, winding steel wires on the soft air pipe and the like. When it is required to meet the processing requirement, since the components with larger strength or hardness are added to the soft air duct on one side where the processing is completed, and the lengths of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are limited, the space occupied by the soft air duct which is fully unfolded in length is larger, so that the materials are stacked between the soft air ducts as the lengths of the soft air ducts which enter the second support arm 621, the fourth support arm 642 and the sixth support arm 662 are larger, compared with the stacking of soft air ducts with a small amount of raw side, the components with larger strength or hardness which are added to the processed parts are difficult to stack between each other. Therefore, in order to save the space required for performing the processing and to facilitate stacking of the processed soft air duct portions, the extent to which the soft air duct is opened by the diameter adjusting assembly mounted on the processing side frame body 542 is adjusted to be greater than the extent to which the soft air duct is opened by the diameter adjusting assembly mounted on the finished side frame body 541, thereby leaving a sizing-up margin for the processed soft air duct portions to facilitate stacking of the processed soft air duct. That is, the distance between the fourth arm 642 and the sixth arm 662 relative to the second arm 621 is less than the distance between the third arm 641 and the fifth arm 661 relative to the first arm 611.
According to some embodiments of the present invention, the transmission assembly includes a first servo motor 710 and a second servo motor 720 mounted on the processed side frame body 542 and the finished side frame body 541, respectively, the first arm 611 and the second arm 621 are directly driven by the first servo motor 710 and the second servo motor 720, respectively, the first arm 611, the third arm 641 and the fifth arm 661 are linked by the same chain, and the second arm 621, the fourth arm 642 and the sixth arm 662 are linked by the same chain, so that the rotational speeds of radial rotation of the processed portion of the soft air duct and the unprocessed portion of the soft air duct are adjusted by the second servo motor 720 and the first servo motor 710, respectively. At the same time, the first support arm 611 and the second support arm 621 are sleeved, and can also allow the two to rotate relatively, and have different rotation speeds.
Preferably, on the premise that the opening degree of the processed part of the soft air pipe is smaller than that of the unprocessed part of the soft air pipe, the rotating speed of the first servo motor 710 is smaller than that of the second servo motor 720, so that the line speed of the processed part of the soft air pipe is ensured to be consistent with that of the unprocessed part of the soft air pipe, wrinkles on the soft air pipe due to inconsistent line speeds of two sides are avoided, adverse effects on the precision of processing and positioning are avoided, and the advantages of space saving and high precision are considered.

In addition, the wire feeding assembly preferably includes a first feeding roller 210 and a second feeding roller 220 disposed on both sides of the wire, and the first feeding roller 210 and the second feeding roller 220 are both cylindrical as a whole. Since the wire used in the present application needs to be spirally wound on the surface of the soft air duct, it is difficult to adjust the uniformity of the wire just before welding the wire so that the wire is attached to the surface of the soft air duct before welding, the present application preferably further comprises a bending adjustment assembly including a frame 310, a feed frame 320, a discharge frame 330 and an adjustment wheel 340, as shown in fig. 7, both the feed frame 320 and the discharge frame 330 being rotatably provided on the frame 310, the straightening assembly being provided on the feed frame 320, the wire feeding assembly being provided on the discharge frame 330, the adjustment wheel 340 being provided between the feed frame 320 and the discharge frame 330, and the adjustment wheel 340 being liftable on the frame 310, so that the degree of bending of the wire can be adjusted in advance by adjusting the angular relationship between the discharge frame 330 and the feed frame 320 and the adjustment wheel 340, thereby obtaining a good attachment degree of the wire to the surface of the soft air duct.
