Description

Technical Field

[0001] The utility model relates to the technical field of shoe upper punching, in particular to a shoe upper leather punching positioning device. Background Art

[0002] Leather is widely used in footwear manufacturing as a shoe upper material due to its unique texture and durability. In the production process of leather uppers, punching is an important process link, which is used to form shoelace holes. However, when punching, the upper leather is prone to displacement, resulting in deviation of the punching.

[0003] A Chinese patent discloses a vamp punching device (authorization announcement number CN220109269U). The patented technology places the vamp on the top of the punching table, and the vamp is pressed and limited by the pressing and positioning component. Then, the punching table and the pressing and positioning component are driven to move to the rear side by the conveying component, so that the vamp is directly below the punching component. The vamp can be punched by the punching component, and the hole spacing of the punching component can be freely adjusted by the spacing adjustment component. In use, it is convenient to process multiple holes at the same time, and the spacing of each punching hole can be freely adjusted, so that multiple punching processes can be completed at one time. The operation is more convenient and fast, which effectively improves the processing efficiency, and does not require the operator to manually perform positioning operations, reducing safety hazards;

[0004] However, it has certain disadvantages: the spacing of the alignment holes on the punching table is fixed. When the spacing of the holes punched by the punching assembly is adjusted, the alignment holes on the punching table cannot be adjusted, and the punching table is not easy to replace, so it does not meet actual processing needs.

DETAILED DESCRIPTION

[0025] See also Figures 1 to 3 and Figure 8 In the embodiment of the utility model, a punching and positioning device for upper leather comprises two support seats 1 and a support plate 2 located between the two support seats 1. A positioning mechanism 3 is arranged on the upper surface of the support seat 1. The positioning mechanism 3 comprises a positioning frame 4. The lower end of the positioning frame 4 is mounted on the upper surface of the support seat 1. Slide grooves 5 are provided on the inner front and rear side surfaces of the positioning frame 4. A threaded rod 6 is threadedly connected through the upper surface of the positioning frame 4. A support block 7 is mounted on the upper end of the threaded rod 6. A positioning plate 8 is rotatably connected to the lower end of the threaded rod 6. The front and rear ends of the positioning plate 8 are slidably connected to the inside of the slide groove 5. An alignment hole 9 is provided inside the support plate 2.

[0026] The whole device is installed at the punching mechanism 20. The number of punching heads on the punching mechanism 20 is equal to the number of alignment holes 9, and they are directly opposite to the alignment holes 9.

[0027] The upper leather to be punched is placed on the surface of the support seat 1 and the support plate 2, and the punching mechanism 20 punches holes to form shoelace holes;

[0028] Rotating the threaded rod 6 can drive the positioning plate 8 to rise and fall. When the positioning plate 8 is lowered to a certain height, the upper leather can be fixed, thereby preventing the upper leather from shifting during punching.

[0029] The support block 7 facilitates the rotation of the threaded rod 6 .

[0030] exist Figure 1 , Figure 2 , Figures 4 to 8 In: A docking groove 10 is provided on one side surface of the support seat 1 facing the support plate 2, and a plurality of docking holes 11 are provided on one side surface of the inner side of the docking groove 10. A docking seat 12 is installed on both left and right ends of the support plate 2. The docking seat 12 is movably located inside the docking groove 10. A sliding hole 13 is provided on the front surface of the docking seat 12, and a docking mechanism 14 is provided inside the docking seat 12. The docking mechanism 14 includes a docking plate 15, and four corners of the docking plate 15 are movably penetrated and connected with a sliding rod 16. The ends of the sliding rod 16 are installed on the left and right side surfaces of the inner side of the docking seat 12. A slider 17 is installed on the front end of the docking plate 15. The slider 17 is slidably connected to the inside of the sliding hole 13. A plurality of docking rods 18 are installed on one side surface of the docking plate 15. The docking rod 18 movably penetrates one side surface of the docking seat 12, and the docking rod 18 is located inside the docking hole 11. A plurality of springs 19 are installed on the other side surface of the docking plate 15, and one end of the spring 19 is installed on one side surface of the inner side of the docking seat 12.

[0031] When the spacing of the holes to be opened on the upper leather is different, the spacing of the punching head on the punching mechanism 20 needs to be adjusted; the slider 17 is pushed away from the support plate 2 to drive the docking rod 18 to leave the inside of the docking hole 11, so that the support plate 2 can be removed, which is convenient for replacing the support plate 2 with different hole spacing;

[0032] The docking groove 10 and the docking seat 12 are both T-shaped when viewed from the front and back, which is convenient for docking between the two.

[0033] The working principle of the utility model is: when in use, the device is installed on the punching mechanism, the upper leather is placed on the support seat 1 and the support plate 2, and then the threaded rod 6 is rotated to drive the positioning plate 8 to descend, so as to fix the upper leather, and then the punching mechanism 20 is opened to punch the upper leather; when the spacing of the holes required for the upper leather is different, the staff can replace or adjust the punching head on the punching mechanism 20, and then push the slider 17 to the side away from the support plate 2 to drive the docking rod 18 to leave the inside of the docking hole 11, remove the support plate 2, and install the new support plate 2 between the two support seats 1.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
