[0031] The technical solution of the present invention can achieve the goal that the traction belt does not need to be rolled during the conveying process by adopting conveying rollers, thereby reducing the problem of breakage of the traction belt before assembly, improving the stability of traction belt conveying, and ensuring the orderliness of assembly; and combining the traction belt with the material conveying at the same time, and then pressing the traction belt and the material together through the rollers for assembly, thereby improving the smoothness of assembly and saving the space occupied by equipment, while also reducing the solid damage and scrapping of materials without traction, saving the time of re-connecting the belt in the next process.

[0032] Among them, Figure 1 As shown, the number of the conveying rollers 320 is at least two, and the same side surface of the traction belt is sequentially connected to the surfaces of all the conveying rollers 320.

By forming a first extrusion and cutting channel between the first pressure rod 420 and the first support platform 430, the flexibility and convenience of the tape splicing operation can be improved, and the increased failure rate caused by complex movements can be avoided.

[0037] Specifically, if Figure 1 and3 As shown, the roller winding device further includes a second belt connecting mechanism 600; the second belt connecting mechanism 600 is connected to the frame 100; the second belt connecting mechanism 600 is arranged between the material conveying mechanism 200 and the roller 520; and the output end of the second belt connecting mechanism 600 is connected to the input end of the first belt connecting mechanism 400, or the output end of the second belt connecting mechanism 600 is connected to the input end of the roller 520. In another embodiment, as Figure 1 As shown, the frame 100 is provided with a second connecting mechanism 600 and a first connecting mechanism 400; the traction belt mechanism 300 is provided between the second connecting mechanism 600 and the first connecting mechanism 400, and the traction belt mechanism 300 is only connected to the first connecting mechanism 400; that is, the material is first squeezed and cut, and then the cut material and the conveying traction belt are squeezed and cut.

[0038] Specifically, in some embodiments, Figure 1 As shown, the second tape splicing mechanism 600 includes a second extrusion cylinder 601, a second pressure rod 602, and a second support platform 603.

The second material conveying roller 212 is connected to the frame 100. The third material conveying roller 213 is used to connect with the other side of the material and convey the material to the roller 520. In other words, the second material conveying roller 212 and the third material conveying roller 213 respectively squeeze and convey the two opposite side surfaces of the material, ensuring the tightness of the material during conveying and preventing the material from folding or wrinkling, thereby improving the stability and orderliness of the assembly.

This structure uses the telescopic driving action of the pushing cylinder 214 to enable the swinging assembly 218 to achieve swinging motion, thereby adjusting the position of the second material conveying roller 212, thereby changing the tensioning performance of the second material conveying roller 212 on the material conveying, thereby improving the stability and orderliness of the assembly. Among them, as Figure 2 As shown, the swing assembly 218 includes a first connecting shaft 215, a rotational positioning shaft 216, and a second connecting shaft 217; the rotational positioning shaft 216 is rotatably connected to the frame 100; one end of the first connecting shaft 215 is connected to the push cylinder 214; the other end of the first connecting shaft 215 is fixedly connected to one end of the second connecting shaft 217; and the other end of the first connecting shaft 215 is movably connected to the surface of the rotational positioning shaft 216; the other end of the second connecting shaft 217 is connected to the second material conveying roller 212.
