Description

Technical Field

[0001] The utility model relates to a shoe upper leather cutting device, belonging to the technical field of leather cutting devices. Background Art

[0002] Upper leather is a crucial component of leather shoemaking. A shoe upper fabric cutting device is a specialized piece of leather cutting equipment specifically designed for this purpose. During operation, the cutting device's cylinder draws air, driving a cutting die downward to press and cut the leather, thereby cutting the upper leather from the material. However, in existing shoe upper leather cutting devices, after cutting, the cylinder retracts, causing the cut leather to become stuck within the cutting die due to its hardness. This can affect the next cut and prevent the cutting device from continuously cutting. Therefore, the present invention proposes a shoe upper leather cutting device to address this issue.

[0018] The following detailed description of the embodiments of the present invention is made in conjunction with the accompanying drawings. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0019] like Figure 1-Figure 2 The top of described U-shaped plate 6 is provided with the support of described support rod 3, and the bottom of described U-shaped plate 6 is fixed with the support of described support rod 3.

[0020] In the above technical solution, a group of springs 10 are installed at the bottom of the U-shaped frame, and a pusher block 11 is installed at the bottom of the spring 10. During the extension of the cylinder 5, the cylinder 5 drives the lifting plate 7 to move downward. The first thing that contacts the top of the cutting table 2 is the pushing block 11. Under the elastic force of the spring 10, the leather with cutting can be pressed, which is convenient for cutting the leather. When the cutting mold 9 finishes cutting the leather, the cylinder 5 is in the process of meeting, and the lifting plate 7 moves upward first, driving the cutting mold 9 to move upward. The pushing block 11 loses its resistance force. Under the elastic restoring force of the spring 10, the pushing block 11 is pushed out of the telescopic channel 8, and the cut leather in the cutting mold 9 can be pushed out, which can avoid the cut leather from being stuck in the cutting mold 9 and affecting the next cutting.

[0021] In the present invention, an inverted first U-shaped mounting frame 12 is provided on the left side of the top of the workbench 1. A set of first transmission rollers 13 are rotatably connected from top to bottom within the first U-shaped mounting frame 12. A first motor 14 is mounted on the rear side of the first U-shaped mounting frame 12. The output shaft of the first motor 14 is fixedly connected to the roller shaft of one of the first transmission rollers 13 located at the lower portion of the first U-shaped mounting frame 12. By providing a set of first transmission rollers 13, the first motor 14 drives the first transmission rollers 13 to rotate. When leather is located between the first transmission rollers 13, the leather can be transported to the cutting table 2.

[0022] In the present invention, an inverted second U-shaped mounting frame 15 is provided on the top right side of the workbench 1. A set of second drive rollers 16 are rotatably connected to the interior of the second U-shaped mounting frame 15 from top to bottom. A second motor 17 is mounted on the rear side of the second U-shaped mounting frame 15. The output shaft of the second motor 17 is fixedly connected to the roller shaft of one of the second drive rollers 16 located at the bottom of the second U-shaped mounting frame 15. The provision of a set of second drive rollers 16 can be used to drive the cut leather waste across the cutting table 2.

[0023] In the present invention, a feeding opening 18 is provided between the second U-shaped mounting frame 15 on the top of the workbench 1 and the cutting table 2. The feeding opening 18 is provided to facilitate the cutting of leather materials from the feeding opening 18 on the workbench 1.

[0024] In the present invention, support rods 19 are provided at the four corners of the bottom of the workbench 1, and a collection frame 20 is placed between the support rods 19. The collection frame 20 is located just below the discharge port 18. The collection frame 20 can be used to collect the cut leather falling from the discharge port 18.

[0025] The working principle of the shoe upper leather cutting device of the utility model is:

[0026] When in use, first pass the leather to be cut through the gap between a group of first transmission rollers 13, and then pull the leather to be cut through the gap between the second transmission rollers 16. The air intake of the cylinder 5 drives the lifting plate 7 to move downward on the slide bar 3. During the downward movement of the lifting plate 7, the pushing block 11 first contacts the surface of the leather to be cut. The lifting plate 7 continues to move downward, the spring 10 retracts, the pushing block 11 retracts into the telescopic channel 8, and the cutting die 9 cuts the leather. After the cutting is completed, the air is discharged by the cylinder 5 and its output end retracts to drive the lifting plate 7 to move upward, and the cutting die 9 moves upward synchronously When the leather material is moved, the spring 10 loses its extrusion force and recovers its deformation, causing the pusher block 11 to slide out of the telescopic channel 8, thereby squeezing the cut leather material stuck in the cutting die 9 out of the cutting die 9 and placing it on the top of the cutting table 2. After that, the second motor 17 and the first motor 14 are started synchronously, driving the first transmission roller 13 and the second transmission roller 16 to rotate and transport the leather material to be cut to the top of the cutting table 2. The cut leather material is driven out of the top surface of the cutting table 2 and falls from the discharge port 18 into the collection frame for collection. After that, the cylinder 5 is aired again to re-cut the uncut leather material on the top of the cutting table 2. The intermittent action between the cylinder 5 and each motor can achieve continuous cutting of the leather material.

[0027] It is worth noting that: in the present invention, the first motor 14 and the second motor 17 are electrically connected to the external power supply through the controller and are controlled by the controller (not shown in the present invention), the cylinder 5 is connected to the external air circuit, and the air inlet and outlet of the cylinder 5 are controlled by the solenoid valve (not shown in the present invention), which is also electrically connected to the external circuit through the controller and its operation is controlled by the controller.

[0028] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
