[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-3 As shown, a positioning mechanism for a leather punching machine includes a pressure plate 2, a support plate 4, and a ferromagnetic substrate 11. The ferromagnetic substrate 11 supports the material. The pressure plate 2 and the support plate 4 are parallel to each other. An electromagnet 7 is fixedly connected to the support plate 4, and the electromagnet 7 is used to magnetically attract and fix the support plate 4 to the ferromagnetic substrate 11. The pressure plate 2 is slidably connected to the support plate 4 through an elastic component 3. The elastic component 3 applies downward pressure to the pressure plate 2 to press the material. In the initial state, the lower end face of the pressure plate 2 is flush with the lower end face of the support plate 4.

[0025] In use, the leather is laid flat on the ferromagnetic substrate 11, and the pressure plate 2 and the support plate 4 are moved to the edge of the leather so that the pressure plate 2 is in contact with the leather and the support plate 4 is not in contact with the leather. At this time, the pressure plate 2 and the support plate 4 have a height difference. The elastic component 3 applies downward pressure to the pressure plate 2 to press the leather. Then the electromagnet 7 is activated to magnetically fix the support plate 4 to the ferromagnetic substrate 11.

[0026] In some embodiments, the elastic component 3 includes a connecting frame 5 and a sliding rod 8. The connecting frame 5 is fixedly connected to the support plate 4, and the sliding rod 8 is fixedly connected to the pressure plate 2. The sliding rod 8 is slidably connected to the connecting frame 5 in the vertical direction, and a spring 9 is provided between the connecting frame 5 and the pressure plate 2. Specifically, a sleeve is fitted on the outer side of the sliding rod 8, and the sleeve is fixedly connected to the connecting frame 5. Preferably, the spring 9 is fitted on the outer side of the sliding rod 8. When a height difference occurs between the pressure plate 2 and the support plate 4, the spring 9 is compressed, applying downward pressure to the pressure plate 2.

[0027] To facilitate adjustment of the pressure applied by the pressure plate 2, the slide rod 8 has an external thread 12 on its outer side near the pressure plate 2, and a nut 13 is connected to the outer thread of the slide rod 8. When adjusting the pressure, rotating the nut 13 adjusts the degree of compression of the spring 9 in its initial state, thereby adjusting the pressure on the pressure plate 2.

[0028] To achieve automated fixing, a distance sensor 10 is installed directly above the pressure plate 2, and the distance sensor 10 is fixedly connected to the connecting frame 5. When the pressure plate 2 and the support plate 4 are moved to the edge of the leather, a height difference is created between the pressure plate 2 and the support plate 4. The distance sensor 10 detects that the distance between the connecting frame 5 and the pressure plate 2 is decreasing, and the electromagnet 7 is activated to fix the support plate 4 to the ferromagnetic substrate 11. Specifically, a handle 6 and a controller 1 are fixedly connected to the connecting frame 5, and both the electromagnet 7 and the distance sensor 10 are electrically connected to the controller 1.

[0029] In order to balance the force at all points of the pressure plate 2, there are multiple elastic components 3, which are arranged in an array along the length of the pressure plate 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
