[0022] Such as Figures 1 - 4As shown in the figure, a cutting device for shoe production includes a workbench 1. In the center of the top of the workbench 1, there is a set of limit rods 5. At the top of the set of limit rods 5, a top plate 6 is fixedly connected. On the top of the top plate 6, there is a cylinder 7. An installation plate 8 is movably connected up and down on the limit rods 5. The output shaft of the cylinder 7 is fixedly connected to the top of the installation plate 8. At the bottom of the installation plate 8, there is a cutter seat 9. At the bottom of the cutter seat 9, a cutting knife 10 is detachably connected. On both the left and right sides of the installation plate 8, there is a set of hinge ears 11. Between the set of hinge ears 11, there is an L-shaped movable plate 12 hinged. When the L-shaped movable plate 12 is parallel to the cutter seat 9, the bottom of the L-shaped movable plate 12 is lower than the bottom of the cutting knife 10. At the bottom of the workbench 1, there are several support legs 13. Between the L-shaped movable plate 12 and the cutter seat 9, there is a set of tension spring assemblies 2. Between the set of tension spring assemblies 2, there is a guiding assembly 3. At a position near the bottom of the side of the L-shaped movable plate 12 far from the cutter seat 9, there is a notch, and a pressure roller assembly 4 is installed in the notch.

[0023] In the above technical solution, by setting the cylinder 7, the action of the cylinder 7 can drive the installation plate 8 to move downward under the limitation of the limit rods 5, so as to drive the cutting knife 10 to move downward to cut the leather placed on the workbench 1. By hinging an L-shaped movable plate 12 on the hinge ears 11 at both the left and right ends of the installation plate 8, when the installation plate 8 moves downward, the pressure roller assembly 4 at the bottom of the L-shaped movable plate 12 will first contact the surface of the leather. When the movable plate continues to move downward, the L-shaped movable plate 12 will move away from one end of the cutting knife 10 under the guidance of the guiding assembly 3. Under the combined action of the torsion spring 403, the tension spring and the rubber roller 401, the leather can be flattened and pressed on the workbench 1, which can make the cutting of the leather by the present invention more convenient and efficient.

[0024] In the present invention, the tension spring assembly 2 includes a first hanging ear 201 and a second hanging ear 202. The first hanging ear 201 is fixedly connected to a position near the edge of the cutter seat 9. The second hanging ear 202 is fixedly connected to one end of the L-shaped movable plate 12 close to the cutter seat 9. There is a height difference between the first hanging ear 201 and the second hanging ear 202. A tension spring body 203 is hung on the first hanging ear 201, and the other end of the tension spring body 203 is hung on the second hanging ear 202.

[0025] In the above technical solution, by hanging the tension spring body 203 on the first hanging ear 201 and the second hanging ear 202, a pulling force is provided for the L-shaped movable plate 12 when the L-shaped movable plate 12 moves away from one end of the cutting knife 10. When the cylinder 7 retracts, the L-shaped movable plate 12 can be pulled back to its original position.

[0026] In the present utility model, the guiding assembly 3 includes a set of first hinge seats 301 and a set of second hinge seats 302. The set of first hinge seats 301 is fixedly connected to the center of the side of the cutter seat 9 close to the L-shaped movable plate 12. The set of first hinge seats 301 is horizontal with the first hanging ear 201. The set of second hinge seats 302 is fixedly connected to the center of the end face of the L-shaped movable plate 12 close to the cutter seat 9. The set of second hinge seats 302 is horizontal with the second hanging ear 202. A telescopic guiding rod 303 is hinged between the set of first hinge seats 301, and the other end of the telescopic guiding rod 303 is hinged between the second hinge seats 302.

[0027] In the above technical solution, by providing the telescopic guiding rod 303, during the downward movement of the mounting plate 8, the moving direction of the L-shaped movable plate 12 can be guided, preventing the L-shaped movable plate 12 from moving towards the cutting knife 10, thus affecting the use of the present utility model. During the retraction of the air cylinder 7, it can prevent the L-shaped movable plate 12 from being pulled close to the cutting knife 10 under the action of the tension spring body 203 when the L-shaped movable plate 12 is reset, enabling the present utility model to perform multiple cuttings.

[0028] In the present utility model, the pressure roller assembly 4 includes a rubber roller 401. Both ends of the rubber roller 401 are provided with roller shafts 402. The rubber roller 401 is located at the notch position, and the roller shafts 402 are rotatably connected to the inner wall of the notch. A torsion spring 403 is sleeved on the roller shafts 402. One end of the torsion spring 403 is fixed on the rubber roller 401, and the other end of the torsion spring 403 is fixed on the inner wall of the notch.

[0029] In the above technical solution, by providing the torsion spring 403 and the rubber roller 401, during the downward movement of the mounting plate 8, when the rubber roller 401 contacts the leather surface, the leather can be flattened by using the friction between the rubber roller 401 and the leather and the torsion of the torsion spring 403, making the cutting position of the leather more accurate and flat.

[0030] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
