[0024] Working principle:
[0025] During use, start the circuit of the motor 15. The motor 15 drives the rotation of the embedded shaft 22 on the inner wall of the bearing 18. The embedded shaft 22 drives the rotation of the rotating shaft 19 through the spline shaft one 20, thereby driving the rotation of the roller shaft 17 to achieve the rolling function. When it is necessary to replace the roller shaft 17 with different thicknesses, rotate the turning handle 7. The turning handle 7 drives the rotation of the turntable 8, and the turntable 8 drives the rotation of the threaded rod 10, thereby driving the slider 13 engaged with it to slide along the chute 11.

When the spline shaft one 20 on the other side of the rotating shaft 19 is inserted into the spline hole 23 in the pressing plate 16, the installation is completed. The installation is simple, the disassembly is convenient, and it is convenient to replace the roller shaft 17 with different thicknesses. The distance between the two roller shafts 17 is fixed, avoiding the influence on the forming of the protective film caused by the offset of the distance.
