Description

TECHNICAL FIELD

[0002] In the printing process of white cardboard, the material needs to be transported using an unwinding machine. The conventional white cardboard unwinding machine is usually equipped with a stainless steel conveying roller, which has stripes on its surface to increase friction, thereby driving the movement of the white cardboard through friction.

[0003] In the patent document with publication number CN220264609U, a roll mechanism for white cardboard processing is proposed. The device includes a mounting frame, a transmission assembly, and a clamping assembly. The mounting frame includes two oppositely arranged mounting plates. The transmission assembly includes a driving roller and a driven roller. White cardboard enters from the input end, passes around the driving roller and the driven roller, and is output from the output end. A drive motor is fixed on the mounting frame, which drives the driving roller to rotate. The clamping assembly includes a clamping roller and an elastic driving component. The clamping roller includes a compression roller and a rotating shaft. The mounting plate is provided with a sliding groove, and the rotating shaft is arranged in the sliding groove. The compression roller is located between the two mounting plates and is arranged in close contact with the driving roller. The elastic driving component abuts against the rotating shaft and compresses the compression roller and the driving roller. The elastic driving component drives the clamping roller to abut against the driving roller, and the two rollers always have a pressing force, which synchronizes the rotation speed of the white cardboard and the driving roller, stabilizes the printing process quality, and improves the processing efficiency of the white cardboard.

[0004] However, when the stripes on the outside of the driving roller wear out during use, the device cannot replace the part with the driving stripes, and the entire driving roller needs to be replaced separately, wasting resources and increasing costs. Second, although the compression roller on the device can generate pressure on the driving roller to stabilize the printing process quality, it is not convenient to replace the compression roller when it is damaged, which reduces the efficiency of maintenance work.
