[0002] Leather shoes refer to shoes with natural leather uppers and leather or rubber, plastic, PU foam, PVC, etc. as soles, which are processed by sewing, gluing or injection molding. Leather shoes are breathable and moisture-absorbent, and have good hygiene properties. They are the highest-quality shoes among all types of shoes. Leather shoe molding refers to the use of the extrusion and moldability of plastics to send loose granular or powdered raw materials from an injection molding machine into a high-temperature barrel for heating, melting and plasticizing, making it a viscous melt, and then filling it into the sole mold at a certain pressure and speed, and squeezing it with the upper. After pressure holding and cooling, a complete leather shoe can be obtained.

[0027] It should be noted that, first, the staff places the leather upper and sole on the top of the fixed plate 5, and the servo motor 301 is started to drive the first circular plate 303 to rotate through the rotating shaft 302 set by the eccentric shaft, and the first circular plate 303 drives the second circular plate 304 to rotate, and the second circular plate 304 pulls the punching rod 307 to move up and down inside the clamping sleeve 7 through the linkage rod 306, and the leather upper and sole are squeezed by the up and down movement of the punching rod 307, and the distance between the upper and lower ends of the second circular plate 304 on the front side of the first circular plate 303 is adjusted by the lifting component 4 to increase or weaken the punching force of the punching rod 307, so as to squeeze uppers and soles of different leathers, and the clamping sleeve 7 is used to limit the punching position of the punching rod 307 through the fixing component 8 to prevent the punching rod 307 from shifting position, and the fixed plate 5 can drive the upper to rotate through the rotating component 6 to squeeze different positions of the upper.

[0028] The lifting assembly 4 includes a movable block 401 fixedly connected to the rear side of the second circular plate 304, the upper and lower ends of the front side of the first circular plate 303 are fixedly connected to the side plates 402, the top of the side plate 402 is fixedly connected to the stepper motor 403, the output end of the stepper motor 403 is fixedly connected to the threaded rod 404, and the sliding rod 405 is fixedly connected between the side plates 402. The left side of the movable block 401 is threadedly connected to the wall surface of the threaded rod 404, and the right side of the movable block 401 is movably connected to the wall surface of the sliding rod 405.

[0032] The fixing component 8 includes a second limiting groove 801 opened at the upper and lower ends of the output end of the connecting plate 701, and the left and right sides of the front side of the support plate 3 are fixedly connected with a fixing block 802, and the front side of the fixing block 802 is provided with a placement hole 803, and the upper and lower ends of the placement hole 803 are provided with rectangular holes 804, and the ends of the rectangular holes 804 close to each other are fixedly connected with springs 805, and the output ends of the springs 805 are fixedly connected with movable plates 806, and the ends of the movable plates 806 close to each other are fixedly connected with fourth limiting blocks 807, and the fourth limiting blocks 807 are located inside the second limiting groove 801.

[0033] It should be noted that when the punching rod 307 needs to be maintained, the staff manually expands the movable plate 806 outward, the spring 805 receives the pressure and deforms, and begins to rebound and shrink. The spring 805 drives the fourth limit block 807 at the bottom of the movable plate 806 to disengage from the inside of the second limit groove 801, and pulls the connecting plate 701 outward, so that the clamping sleeve 7 is separated from the left and right sides of the punching rod 307, thereby facilitating the maintenance of the punching rod 307.

[0035] It should be noted that when the hydraulic rod 604 is started, the hydraulic rod 604 pushes the tooth plate 605 to move forward or backward through the output end. During the movement, the tooth plate 605 pushes the gear 602 to rotate forward or reversely. The gear 602 drives the fixed plate 5 to rotate forward or reversely through the connecting rod 603, so that the fixed plate 5 drives the shoe upper to rotate during the stamping process so that different positions of the shoe upper can be stamped.

[0036] In summary: first, the staff places the leather upper and sole on the top of the fixed plate 5, and the servo motor 301 starts to drive the first circular plate 303 to rotate through the rotating shaft 302 set by the eccentric shaft. The first circular plate 303 drives the second circular plate 304 to rotate, and the second circular plate 304 pulls the punching rod 307 to move up and down inside the clamping sleeve 7 through the linkage rod 306. The leather upper and sole are squeezed by the up and down movement of the punching rod 307, and the distance between the upper and lower ends of the second circular plate 304 on the front side of the first circular plate 303 is adjusted by the lifting component 4 to increase or weaken the punching force of the punching rod 307 to squeeze uppers and soles of different leathers. The clamping sleeve 7 is used to limit the punching position of the punching rod 307 through the fixing component 8 to prevent the punching rod 307 from shifting.
