[0002] Leather is divided into artificial leather, synthetic leather and natural leather. Leather is commonly used in industries such as manufacturing shoes, leather clothes and other products. After the leather is processed, in order to avoid the irregularity of the side of the leather or for decorating the shoe upper, the side of the leather is usually hemmed and then sewn. For the convenience of hemming, people usually place the leather on a hemming machine to hem the side of the leather.

[0003] For example, the utility model patent with the publication number of CN217324139U discloses a leather hemming device. The device places the leather on a workbench, and then presses and fixes the two ends of the leather by moving the pressing rods on both sides. The rotating shaft is rotatably installed on the workbench, and extrusion plates are fixedly installed on both sides of the rotating shaft. The leather is hemmed and extruded by rotating the extrusion plates on both sides.

[0004] However, when extruding the leather, when the pressing rods that may fix the leather rotate with the extrusion plates, the two pressing rods may contact and collide, making it difficult to rotate the two extrusion plates to 90 degrees, so that the two extrusion plates are fitted together, which may cause incomplete extrusion of the leather and the edges of the hem may open again subsequently. Summary of the Utility Model

[0005] The utility model provides a leather material hemming machine, which solves the problem that in the prior art, when bending the edge of the leather, the bending effect of the leather may be poor due to the blocking of the fixing rod.
