The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and/or" used herein includes any and all combinations of one or more related listed items.

Embodiment 1: As shown in FIG1 , a spray device of a dry fiber band composite equipment is installed between a carbon fiber unwinding area and a hot pressing area, and includes: a first guide roller 1 is arranged near the carbon fiber unwinding area; a reverse roller 2 is arranged on the side of the first guide roller 1 away from the unwinding area, and is fixed to a first bracket plate 3 with the first guide roller 1; a spray gun 4 is provided above the other side of the reverse roller 2; a baffle 5 is provided on the other side of the spray gun 4; wherein, a first water collecting box 6 is provided below the spray gun 4, a second water collecting box 7 is provided below the reverse roller 2, a mesh bracket 8 is also provided on the side of the baffle 5 away from the spray gun 4, and a mesh positioning roller 9 is also provided between the baffle 5 and the mesh bracket 8.

The specific implementation process of the present invention is that the mesh is passively unwound, passes through the mesh positioning roller 9, and enters the spray area; the spray gun 4 sprays the emulsion prepared with resin powder on the mesh surface in the form of atomization; it passes through the mesh reverse roller 2 and overlaps with the carbon fiber to the heating fixed area; when the equipment is winding, the winding drives the mesh and carbon fiber to be passively unwound, and the mesh is unwound with the taper tension setting torque through the magnetic powder brake; the carbon fiber controls the magnetic powder brake according to the set tension through the output of the tension sensor 10, and then outputs a stable torque; while the equipment is winding, the air pressure proportional valve outputs a stable air pressure to the spray solenoid valve; the spray solenoid valve obtains an output signal when the equipment is winding, and outputs the air pressure to the spray gun 4, and the spray gun sprays the emulsion on the mesh surface in an atomized form; finally, it is heated and wound up, and when the equipment stops winding, the spray solenoid valve stops outputting, thereby closing the spray.

In the present invention, a tension sensor 10 is also provided below the first water collecting box 6. The setting of the tension sensor 10 enables real-time monitoring and control of the tension of the carbon fiber or mesh during operation. Accurate tension control is the key to ensuring product quality, especially in composite material processing, where the uniformity and stability of tension have an important impact on the performance of the final product. Through the tension sensor 10 and the control system, devices such as magnetic powder brakes can be adjusted in real time to ensure that the carbon fiber or mesh maintains a constant tension during processing, thereby improving the quality and stability of the product; the horizontal height of the reverse roller 2 is higher than the height of the first guide roller 1, which helps to optimize the flow and path of the carbon fiber or mesh, reduce the bending and wrinkling of the material during transmission, and maintain the flatness of the material. The smooth flow of the material is conducive to the smooth progress of subsequent processing steps, such as emulsion spraying, heating and fixing, etc.

In this solution, a second guide roller 11 is provided on the other side of the mesh support 8. The primary function of the second guide roller 11 is to ensure that the carbon fiber and the mesh can continue to move along the predetermined path after passing through the spraying area, and to keep the two in stable alignment during the process. Stable guidance helps to reduce the offset or distortion of the carbon fiber and the mesh, and ensure that they can accurately overlap in the subsequent processing steps. The second guide roller 11 also preliminarily presses the carbon fiber and the mesh together through a certain pressure. This preliminary pressing helps to make the carbon fiber and the mesh fit more closely, laying a good foundation for the subsequent heating and fixing steps. The preliminary pressing can also reduce the movement or dislocation of the carbon fiber and the mesh during the heating and fixing process, and improve the yield and quality of the product. Since the second guide roller 11 has the functions of guiding and preliminary pressing, it can ensure that the carbon fiber and the mesh remain stable during the process, reducing the downtime and scrap rate in the production process.

In the present invention, the height of the baffle 5 is higher than the height of the spray gun 4. The main function of the baffle 5 is to prevent the emulsion from splashing to other parts of the equipment or the operating area during the spraying process. Since the height of the baffle is higher than the spray gun, it can ensure that the emulsion is effectively confined in the spraying area, reducing unnecessary waste and potential pollution.

In the present invention, the spray gun 4 is fixed on the thin rod 12, and the thin rod 12 is connected to the second bracket plate 13 through oblong holes arranged at both ends of the thin rod 12 for easy height adjustment. The thin rod 12 is connected to the second bracket plate 13 through the oblong holes. This connection method allows the thin rod to move up and down within a certain range, thereby realizing the height adjustment of the spray gun 4, so that the height of the spray gun can be accurately adjusted according to specific needs to adapt to mesh or carbon fiber materials of different specifications, ensuring that the emulsion can be sprayed on the material evenly and accurately; the design of the oblong holes enables the thin rod 12 to remain stable during movement, avoiding equipment failure or safety accidents caused by shaking or tilting. This structural setting also improves the stability and reliability of the equipment and extends the service life of the equipment.

In the present invention, the lower cut surface of the mesh positioning roller 9 is consistent with the horizontal height of the upper cut surface of the reverse roller 2. When the lower cut surface of the mesh positioning roller 9 is consistent with the horizontal height of the upper cut surface of the reverse roller 2, the mesh and carbon fiber can be accurately aligned during the transmission process. This alignment is crucial for the subsequent processing because it ensures that the mesh and carbon fiber can be combined evenly and consistently. The width of the first water collecting box 6 and the second water collecting box 7 is greater than the width of the carbon fiber and the mesh to effectively collect excess liquid (such as emulsion, glue, etc.) that may be generated during the processing. These liquids may splash due to the operation of the spray gun 4 or the movement of the material. If there is no appropriate collection device, it may cause pollution of the working environment and damage to the equipment. The first water collecting box 6 is installed at the bottom of the reverse roller 2, which can not only effectively collect excess emulsion, but also prevent the emulsion from falling and damaging the carbon fiber below.

Embodiment 2: As shown in FIG2 , a control method for a spray device of a dry fiber tape composite device comprises the following steps:

The mesh is passively unwound, passes through the mesh positioning roller, and enters the spraying area;

The spray head sprays the emulsion prepared with resin powder onto the mesh surface in the form of atomization;

Pass through the mesh reverse roller to overlap with the carbon fiber to the heating and fixing area;

When the equipment is reeling, the reeling drives the mesh and carbon fiber to unwind passively. The mesh passes through the magnetic powder brake at a taper

Tension setting torque unwinding;

The carbon fiber controls the magnetic powder brake according to the set tension through the output of the tension feedback device, and then outputs a stable torque;

While the equipment is winding, the air pressure proportional valve outputs stable air pressure to the spray solenoid valve;

The spray solenoid valve receives an output signal when the equipment is winding and outputs air pressure to the spray gun, which then sprays the emulsion onto the mesh surface in atomized form.

Finally, it is heated and then reeled up. When the equipment stops reeling, the spray solenoid valve stops outputting, thereby closing the spraying.
