[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In shoe production, an automatic last pulling machine is needed. The utility model provides an automatic last pulling machine for shoe production, which is specially used for shoe last removal operations. Compared with an automatic last pulling machine for shoe production with publication number CN 207152058 U, this device uses double pressure blocks to act on the top and bottom ends of the shoe last at the same time, and cooperates with the robotic arm to synchronously descend to clamp, demould and unload the material, which can remove the mold more quickly, thereby better reducing manual intervention and reducing operational safety hazards. Example

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] An automatic shoe last pulling machine for producing shoes includes a processing table 1, a baffle 2 is fixedly installed on one side of the top of the processing table 1, a long plate 3 is slidably connected to the top of the inner wall of the baffle 2, and a short plate 4 is slidably connected to the bottom of the inner wall of the baffle 2. Extension rods 5 are fixedly installed on the adjacent side and the non-adjacent side of the long plate 3 and the short plate 4. One end of the two extension rods 5 is fixedly connected to a pressure head 6. A mechanical arm 7 is provided on one side of the extension rod 5 at the top. By simultaneously acting on the top and bottom ends of the shoe last 12 with the double extension rods 5 and the pressure head 6, the demoulding process can be completed more quickly, reducing the production cycle, and then combined with the machine The mechanical arm 7 moves synchronously and can complete the clamping and demoulding immediately after the shoe last is removed, thereby realizing automated operation, reducing the complexity of manual operation, and reducing the risk of human error. The two extension rods 5 are of the same size, and the two pressing heads 6 are of the same size. The shoe last 12 is squeezed by two sets of extension rods 5 and pressing heads 6. The extension rods 5 and pressing heads 6 at the bottom first squeeze the shoe last 12 to achieve the separation of the front part of the shoe last 12, and the extension rods 5 and pressing heads 6 at the top then squeeze the rear part of the shoe last 12 to achieve the separation of the rear part, so that it is convenient for the subsequent mechanical arm 7 to clamp and demould the shoe last 12.

[0024] In this embodiment, brackets 8 are fixedly installed on both sides of the middle part of the top of the processing table 1, mounting plates 9 are fixedly installed on the top of the two brackets 8, and a mounting seat 10 is fixedly installed in the middle part of the top of the mounting plate 9. A positioning column 11 is installed on the top of the processing table 1, and the outer wall of the positioning column 11 is provided with a shoe last 12. The setting of the bracket 8 and the mounting plate 9 plays the role of installing the mounting seat 10, and the setting of the positioning column 11 plays the role of fixing the shoe last 12, which can limit the shoe last 12 to remain stable when the shoe last is pulled out.

[0025] In this embodiment, one end of the robotic arm 7 is fixedly mounted with the bottom end of the long board 3, and the position of the robotic arm 7 corresponds to the position of the shoe last 12. The setting of the robotic arm 7 can quickly and accurately complete the shoe last removal operation, reduce manual intervention, improve production efficiency, and reduce errors caused by human factors.

[0026] In this embodiment, a hydraulic cylinder 13 is fixedly installed in the middle of the other side of the top of the processing table 1. The top fixed sleeve of the output end of the hydraulic cylinder 13 is provided with a mounting ring 14. One end of the long plate 3 is fixedly connected to the outer wall of the mounting ring 14. The cooperation between the hydraulic cylinder 13 and the mounting ring 14 drives the long plate 3 to rise and fall.

[0027] In this embodiment, a connecting block 15 is fixedly installed at a non-adjacent corner on the adjacent side of the long board 3 and the short board 4, and a rack 16 is fixedly connected to the corresponding end of the two connecting blocks 15. A gear 17 is rotatably installed in the middle of the inner wall of the baffle 2, and the adjacent sides of the two racks 16 are meshed with the outer wall of the adjacent gear 17. The meshing cooperation between the rack 16 and the gear 17 plays a role in driving the long board 3 and the short board 4 to approach each other, and further drives the two sets of extension rods 5 and the pressure head 6 to approach each other, and can also drive the mechanical arm 7 to approach the shoe last 12 to realize shoe last removal. Slide grooves are provided on both sides of the inner wall of the baffle 2, and the backs of the two racks 16 are slidably connected to the inner walls of the adjacent slide grooves. The setting of the slide grooves plays a role in assisting the rack 16 to slide stably in the slide grooves.

[0028] Working principle: When in use, by driving the hydraulic cylinder 13 to operate, the long plate 3 is driven to descend under the connection of the mounting ring 14, and further drives the robotic arm 7 to approach the shoe last 12 for clamping and demolding. At the same time, the long plate 3 descends, driving a corresponding set of connecting blocks 15 and rack 16 to slide vertically and descend in the slide groove. Due to the engagement between the rack 16 and the gear 17, the gear 17 can be driven to rotate, so that another rack 16 can be driven to rise in the slide groove, and further driven to rise under the connection of the connecting block 15, thereby achieving the effect of the short plate 4 and the long plate 3 approaching each other, and further driving the extension rod 5 and the pressure head 6 to synchronously squeeze the top and bottom ends of the shoe last 12, so that the positioning column 11 is disengaged from the shoe last 12. After the operation is completed, the robotic arm 7 can clamp the shoe last 12 for demolding and unloading.
