[0002] In leather processing, the leather needs to be wound up using winding equipment.

[0003] For example, Chinese patent CN220866667U describes a leather winding machine. Addressing the problem that existing leather winding machines, when placed on an air shaft, cannot be properly centered, leading to deviations and making it difficult to quickly determine the thickness of the wound leather after a period of winding, the following solution is proposed: It includes a base, a worktable fixedly connected to the top of the base, a side plate fixedly connected to one side of the worktable, an air shaft mounted on one side of the side plate, a winding drum fitted onto the outer wall of the air shaft, and a fixing plate fixedly fitted onto the outer wall of the air shaft. In this invention, by setting scale lines, the thickness of the wound leather can be determined. After the baffle moves laterally, the insert rod enters the groove to prevent the baffle from springing back. The L-shaped plate drives the push rod to move laterally, which in turn pushes the winding drum laterally, helping to remove the winding drum.

[0004] The winding of coated leather requires the laying of diaphragms between the leather layers. The patent does not design the diaphragm supply and pressing result.
