Specifically, it should be noted that the first deviation correcting roller 220 is fixedly sleeved on the outer peripheral side surface of the first roller core 230, so that when the first roller core 230 rotates, the first deviation correcting roller 220 also rotates correspondingly, thereby driving the material belt to be transported, and when the first roller core 230 moves laterally under the action of the traversing assembly 500, the first deviation correcting roller 220 also moves laterally along with the first roller core 230.
In addition, the first bending roller 210 is movably sleeved on the outer peripheral side surface of the first roller core 230, and the first bending roller 210 can relatively move with the first roller core 230 along the axial direction of the first roller core 230. Therefore, when the first roll core 230 is moved laterally by the traverse assembly 500, the position of the first bending roll 210 is fixed, so that it does not move laterally along with the first roll core 230.

Specifically, when the driving end of the rotating assembly 600 is connected to the first roller assembly, the driving end of the rotating assembly 600 directly drives the first roller assembly to rotate, and the second roller assembly rotates synchronously under the friction action of the material belt because the material belt is clamped by the first roller assembly and the second roller assembly.
In addition, specifically, when the driving end of the rotating assembly 600 is connected to the second roller assembly, the driving end of the rotating assembly 600 directly drives the second roller assembly to rotate, and the first roller assembly rotates synchronously under the friction action of the material belt because the material belt is clamped by the first roller assembly and the second roller assembly.

Specifically, when the material belt needs to be clamped and transported between the first roller conveying assembly and the second roller conveying assembly, the second roller conveying assembly can be driven to ascend by the lifting assembly 700, so that the distance between the first roller conveying assembly and the second roller conveying assembly is reduced until the material belt can be clamped between the first roller conveying assembly and the second roller conveying assembly.
In addition, specifically, when the material belt stops transporting and needs to be taken out of the material belt, the second roller feeding assembly can be driven to descend through the lifting assembly 700, so that the distance between the first roller feeding assembly and the second roller feeding assembly is increased, and the material belt can be taken out from between the first roller feeding assembly and the second roller feeding assembly by a worker.
In order to independently lift the second roller assembly, the first bending roller 210 corresponds to one fixing member 410, the second bending roller 310 corresponds to the other fixing member 410, and the fixing member 410 corresponding to the second bending roller 310 is mounted at one end of the mounting base 400 and can slide up and down along the mounting base 400.
