Description

Technical Field

[0001] The invention belongs to the technical field of insole production, and in particular relates to a punching device used for insole production. Background Art

[0002] The production process of insoles can be roughly divided into the following steps: Raw material preparation: Select suitable materials, such as foam, SBR rubber, PU, ​​EVA, etc., and select corresponding materials according to different types of shoes (such as sports shoes or casual shoes); Production process: a. Mold making: This is the key link. The size, precision and production process of the mold directly affect the size and quality of the insole; b. Cutting, core pulling, and assembly: Cut, core pull and assemble the materials into the prototype of the insole according to the design requirements; c. Drying, molding, compacting, and bonding: Through the processes of drying, molding, compacting and bonding, the materials are shaped and fixed; Product quality inspection: The finished insoles need to undergo strict quality inspections such as appearance inspection, dimensional accuracy inspection, pressure test, bending test, etc. to ensure that their quality meets customer requirements; Finally, the production is completed through packaging and molding.

[0003] When cutting insoles, cutting and punching are usually used. The punching method is mostly to achieve cutting by punching materials through a customized insole mold. However, the existing punching device often requires manual labor to take out the punched insoles one by one after punching. This method will cause the manual labor to be synchronized with the machine during the production process, otherwise it will lead to a decrease in production efficiency. At the same time, after taking out the insoles, they need to be stacked one by one. When punching multiple pairs of insoles at a time, the labor intensity of the workers is relatively high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a punching device for insole production.

[0005] The technical solution adopted to solve the above technical problems is: to provide a punching device for insole production, comprising a workbench, one side of the workbench is fixedly connected to an insole stacking mechanism, an insole plate is placed on the top of the workbench and the insole stacking mechanism, and a plurality of formed insoles are placed on the top of the insole stacking mechanism;

[0006] A supporting driving mechanism is arranged between the front end and the rear end of the workbench, a connecting mechanism is slidably connected to the bottom of the workbench, a plurality of ejection mechanisms are slidably connected to one side of the connecting mechanism, and a plurality of punching die mechanisms are slidably connected to the bottom of the connecting mechanism.

[0007] Furthermore, the insole stacking mechanism includes a mechanism shell fixedly connected to one side of the workbench, a bottom fixing plate is fixedly connected to the bottom of the inner wall of the mechanism shell, a plurality of limit rods are slidably connected to the bottom fixing plate, the outer walls of the plurality of limit rods are fixedly connected to the limiting discs at the top position of the bottom fixing plate, the bottoms of the plurality of limit rods are spirally connected to the first nut seat, a movable support plate is slidably connected to the top of the inner wall of the mechanism shell, the front and rear ends of the movable support plate are fixedly connected to the limiting extension plate, both sides of the front and rear end surfaces of the mechanism shell are fixedly connected to the limiting shell, the inner walls of the plurality of limit shells are fixedly connected to arc-shaped metal springs, and the outer sides of the interiors of the plurality of limit shells are slidably connected to the limiting racks.

[0008] Through the above technical scheme, after completing one stamping, the insole plate is pulled to the next stamping position, the pulling distance is slightly greater than the length of the formed insole, and the stamping is repeated. At the same time, when the connecting mechanism descends, multiple ejection mechanisms will be driven to descend, and then the formed insole that appeared in the previous punching process will be ejected, so that it falls on the top of the movable support plate. In the process of repeated work, the formed insole will be continuously accumulated. Therefore, when the thickness of the accumulated formed insole is large, the movable support plate will be pushed by extruding the formed insole. The movable support plate will descend and extrude the limiting rack through the limiting extension plates at both ends, and then extrude the arc-shaped metal spring sheet. Under the condition that the arc-shaped metal spring sheet continuously generates a reaction force, the limiting extension plate will be squeezed downward for a short distance, and the limiting extension plate will be re-engaged with the limiting rack, and under the limit of multiple limiting rods, the stacking of the insoles is automatically completed. Subsequently, only the outermost limiting rod needs to be moved to take out the stacked insoles.

[0009] Furthermore, the bottoms of the plurality of limit rods are all threaded structures.

[0010] Through the above technical solution, while ensuring that the locking and fixing of the limit rod can be completed through the first nut seat, before use, multiple limit rods are slid according to the shape and size of the insole, so that the molded insole can be roughly limited to avoid deviation and tipping during the stacking process.

[0011] Furthermore, the supporting driving mechanism includes two side supporting plates respectively arranged at the front end and the rear end of the insole stacking mechanism, a rotating crankshaft is rotatably connected between the tops of the two side supporting plates, a transmission large gear is fixedly connected to the front end of the rotating crankshaft, a brake pad assembly is installed between the rear end of the rotating crankshaft and the rear end side supporting plate, a connecting plate is fixedly connected to the center between the two side supporting plates, a motor mounting seat and a fixed shaft sleeve are respectively fixedly connected to one side of the side supporting plate located at the front end of the connecting plate, a driving motor is fixedly connected to the top of the motor mounting seat, a driving pinion is fixedly connected to the output end of the driving motor, a gear guard is fixedly connected to the front end surface of the side supporting plate located at the front end of the connecting plate, and a mechanism guard is fixedly connected between the tops of the two side support plates.

[0012] Through the above technical solution, the drive motor is started to drive the drive pinion to rotate, and drives the transmission gear meshing with it, so that the rotating crankshaft can complete the rotation between the two side support plates. At the same time, when the machine drives the insole plate, it can continuously perform rapid punching operations and complete the final deceleration work through the brake pad assembly.

[0013] Furthermore, the connecting mechanism includes a plurality of rotating connecting blocks rotatably connected to the outer wall of the rotating crankshaft, the bottoms of the plurality of rotating connecting blocks are rotatably connected to the first fixed rotating shaft, the bottoms of the plurality of first fixed rotating shafts are fixedly connected to connecting sleeves, a bottom limiting shell is fixedly connected between the bottoms of the plurality of connecting sleeves, one side of the bottom limiting shell is fixedly connected to a side extending support rod, the side extending support rod is provided with a scale on the side away from the bottom limiting shell, the front end of one side of the bottom limiting shell is fixedly connected to the second fixed rotating shaft, the second fixed rotating shaft is rotatably connected to a rotating limiting plate, the center spiral of the rotating limiting plate is connected to a locking threaded rod, the rear end of the locking threaded rod is rotatably connected to an extrusion push plate, and a bolt assembly is installed between the side of the rotating limiting plate away from the second fixed rotating shaft and the bottom limiting shell.

[0014] Through the above technical scheme, before use, the corresponding punching die mechanism is selected according to the size and model of the punching insole, and the bolt assembly is removed during installation, and the locking threaded rod is rotated to pull the extrusion push plate to make it detach from the bottom limit shell, and then the rotating limit plate is rotated to open, and the punching die mechanism is slid and installed according to the structure inside the bottom limit shell. Multiple punching die mechanisms are fitted together until the maximum number is added, and then the rotating limit plate is rotated to reset, and then fixed by the bolt assembly, and finally the locking threaded rod is rotated to push the extrusion push plate into the inner wall of the bottom limit shell until the extrusion push plate contacts the outermost punching die mechanism, thereby completing the fixation of multiple punching die mechanisms.

[0015] Furthermore, the rotation limiting plate is an L-shaped structure, and the extrusion push plate and the bottom limiting shell are slidably connected.

[0016] Through the above technical solution, the L-shaped structure of the rotating limit plate ensures that the extrusion push plate can be stored inside the rotating limit plate, and thus will not affect the rotation and opening of the rotating limit plate. At the same time, the extrusion push plate and the bottom limit shell are slidingly connected, ensuring that the extrusion push plate can be fully fitted with the punching die mechanism.

[0017] Furthermore, the ejection mechanism includes an adjusting threaded rod slidably connected to the side extending support rod, the outer wall of the adjusting threaded rod is fixedly connected to a U-shaped limiting plate, one side of the rear end surface of the U-shaped limiting plate is fixedly connected to a side pointer, the bottom of the adjusting threaded rod is fixedly connected to a bottom ejecting block, and the top of the adjusting threaded rod is spirally connected to a second nut seat.

[0018] Through the above technical solution, before use, according to the shape and size of the insole, the positions of multiple adjusting threaded rods are moved so that they are directly above the corresponding insoles, and then the second nut seat is used to complete the locking and fixing. When the connecting mechanism descends, the bottom ejecting blocks in the multiple ejecting mechanisms will be driven to descend, and then the formed insole that appeared in the previous punching process will be ejected and fall on the top of the movable support plate. At the same time, when moving the position of the adjusting threaded rod, the position between each two adjusting threaded rods can be determined by the cooperation of the side pointer and the scale according to the width of the punching die mechanism, thereby improving the adjustment speed.

[0019] Furthermore, the punching die mechanism includes a die shell slidably connected to the inner wall of the bottom limit shell, two punching tools are fixedly connected to the bottom of the die shell, a locking convex plate is fixedly connected to the rear end of the die shell, two sliding sleeves corresponding to the punching tools are slidably connected to the bottom of the die shell, two groups of mounting pads are fixedly connected to the top inner surface of the die shell, and reset springs are fixedly connected between the two groups of mounting pads and the corresponding two sliding sleeves.

[0020] Through the above technical solution, when in use, as the overall connecting mechanism moves downward, it will drive multiple punching die mechanisms until the sliding shell contacts the insole plate and then continues to descend. At this time, the sliding shell stops moving and begins to compress multiple reset springs until the punching tool contacts the insole plate and then goes deeper to complete the punching. During the resetting process, the punching tool leaves the insole plate. Under the action of the reset spring, the sliding shell always fits the insole plate to avoid the situation where the cut molded insole is stuck inside the punching tool.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention designs the cooperation between the insole stacking mechanism and the ejection mechanism. When the connecting mechanism descends, it will drive multiple ejection mechanisms to descend, thereby ejecting the formed insoles produced in the previous punching process and causing them to fall on the top of the movable support plate. In the process of repeated work, the formed insoles are continuously accumulated. Since the descending position of the bottom top block is fixed, when the thickness of the accumulated formed insoles is large, the movable support plate is pushed by squeezing the formed insoles. The movable support plate descends and squeezes the limiting rack through the limiting extension plates at both ends, thereby squeezing the arc-shaped metal spring sheet. When the arc-shaped metal spring sheet continuously generates a reaction force, the limiting extension plate is squeezed downward for a short distance, and the limiting extension plate is re-aligned with the limiting rack. The invention can automatically stack the insoles under the limit of multiple limit rods, thereby realizing automatic stacking of the insoles, avoiding the need to manually take out the insoles one by one and the subsequent stacking and placing of the insoles, reducing the labor intensity of manual labor and improving production efficiency; (2) The invention realizes that during the process of driving the punching, the ejection mechanism can also be used to eject the molded insoles, thereby avoiding the need for additional driving equipment and reducing the cost of the overall device. At the same time, during the punching process, the punching tool contacts the insole plate and then penetrates to complete the punching. During the resetting process, the punching tool leaves the insole plate. Under the action of the resetting spring, the sliding shell always fits the insole plate, thereby avoiding the situation where the cut molded insole is stuck inside the punching tool.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] like Figure 1-Figure 6 As shown, a punching device for insole production in this embodiment includes a workbench 1, one side of the workbench 1 is fixedly connected to an insole stacking mechanism 2, the insole stacking mechanism 2 includes a mechanism shell 201 fixedly connected to one side of the workbench 1, the bottom of the inner wall of the mechanism shell 201 is fixedly connected to a bottom fixing plate 202, a plurality of limiting rods 203 are slidably connected to the bottom fixing plate 202, the outer walls of the plurality of limiting rods 203 are fixedly connected to limiting discs 204 at the top position of the bottom fixing plate 202, the bottoms of the plurality of limiting rods 203 are spirally connected to a first nut seat 205, the top of the inner wall of the mechanism shell 201 is slidably connected to a movable support plate 206, and the movable support plate 206 is slidably connected to the bottom of the inner wall of the mechanism shell 201. The front and rear ends of the support plate 206 are fixedly connected to the limited extension plate 207, the two sides of the front and rear end surfaces of the mechanism shell 201 are fixedly connected to the limited shell 208, the inner walls of the plurality of limited shells 208 are fixedly connected with arc-shaped metal springs 209, and the outer sides of the interiors of the plurality of limited shells 208 are slidably connected to the limited rack 210. After completing one stamping, the insole plate 3 is pulled to the next stamping position, and the pulling distance is slightly greater than the length of the formed insole 4. The stamping is repeated, and at the same time, when the connecting mechanism 6 descends, it will drive the plurality of ejection mechanisms 7 to descend, thereby ejecting the formed insole 4 that appeared in the previous punching process, so that it falls on the movable support plate 206. At the top, the formed insole 4 will be continuously accumulated during the repeated work process. Therefore, when the accumulated formed insole 4 is thicker, the formed insole 4 will be squeezed to push the movable support plate 206, and the movable support plate 206 will drop and squeeze the limiting rack 210 through the limiting extension plates 207 at both ends, thereby squeezing the arc-shaped metal spring piece 209. When the arc-shaped metal spring piece 209 continuously generates a reaction force, the limiting extension plate 207 will be squeezed downward for a short distance, and the limiting extension plate 207 will be re-engaged with the limiting rack 210 (due to the small mass of the insole, it is not necessary to consider that the mass of the accumulated insole increases and causes the limiting extension plate 207 to continue to move). The stacking of the insoles is automatically completed under the limitation of multiple limiting rods 203. Subsequently, the stacked insoles can be taken out by moving the limiting rod 203 at the outermost position. The bottoms of the multiple limiting rods 203 are all threaded structures. After ensuring that the limiting rods 203 can be locked and fixed by the first nut seat 205, before use, according to the shape and size of the insole, slide the multiple limiting rods 203 so that they can roughly limit the formed insole 4 to avoid deviation and tipping during the stacking process. An insole plate 3 is placed on the top of the workbench 1 and the insole stacking mechanism 2, and multiple formed insoles 4 are placed on the top of the insole stacking mechanism 2.

[0040] like Figure 1-Figure 9 As shown, a support driving mechanism 5 is arranged between the front end and the rear end of the workbench 1, and the support driving mechanism 5 includes two side support plates 501 respectively arranged at the front end and the rear end of the insole stacking mechanism 2, a rotating crankshaft 502 is rotatably connected between the tops of the two side support plates 501, a transmission gear 503 is fixedly connected to the front end of the rotating crankshaft 502, a brake pad assembly 504 is installed between the rear end of the rotating crankshaft 502 and the rear end side support plate 501, a connecting plate 505 is fixedly connected to the center between the two side support plates 501, and a motor mounting seat 506 and a fixed shaft sleeve 507 are respectively fixedly connected to one side of the side support plate 501 located at the front end of the connecting plate 505, A driving motor 508 is fixedly connected to the top of the mounting seat 506, and a driving pinion 509 is fixedly connected to the output end of the driving motor 508. A gear protection cover 510 is fixedly connected to the front end surface of the side support plate 501 located at the front end of the connecting plate 505, and a mechanism protection cover 511 is fixedly connected between the tops of the two side support plates 501. Starting the driving motor 508 drives the driving pinion 509 to rotate, and drives the large transmission gear 503 meshing with it, so that the rotating crankshaft 502 can complete the rotation between the two side support plates 501. At the same time, when the machine drives the insole plate 3, it can continuously perform rapid punching operations, and complete the final deceleration work through the brake pad assembly 504.

[0041] like Figure 1-Figure 13As shown, the bottom of the workbench 1 is slidably connected with a connecting mechanism 6, and the connecting mechanism 6 includes a plurality of rotating connecting blocks 601 rotatably connected to the outer wall of the rotating crankshaft 502, the bottoms of the plurality of rotating connecting blocks 601 are rotatably connected with a first fixed rotating shaft 602, the bottoms of the plurality of first fixed rotating shafts 602 are fixedly connected with a connecting sleeve 603, the bottoms of the plurality of connecting sleeves 603 are fixedly connected with a bottom limiting shell 604, one side of the bottom limiting shell 604 is fixedly connected with a side extension support rod 605, and the side extension support rod 605 is away from the bottom limiting shell 604. A scale 606 is provided on one side of the bottom limit shell 604, a second fixed rotating shaft 607 is fixedly connected to the front end of one side of the bottom limit shell 604, a rotation limit plate 608 is rotatably connected to the second fixed rotating shaft 607, a locking threaded rod 609 is spirally connected to the center of the rotation limit plate 608, and an extrusion push plate 610 is rotatably connected to the rear end of the locking threaded rod 609, and a bolt assembly 611 is installed between the rotation limit plate 608 and the bottom limit shell 604 on the side away from the second fixed rotating shaft 607. Before use, select the corresponding blanking die according to the size and model of the blanking insole. The punching die mechanism 8 is installed. When installing, the bolt assembly 611 is removed, and the locking threaded rod 609 is rotated to pull the extrusion push plate 610 to disengage it from the bottom limit shell 604, and then the rotation limit plate 608 is rotated to open, and the punching die mechanism 8 is slidably installed according to the structure inside the bottom limit shell 604. Multiple punching die mechanisms 8 fit each other until the maximum number is added, and then the rotation limit plate 608 is rotated to reset, and then fixed by the bolt assembly 611, and finally the locking threaded rod 609 is rotated to push the extrusion push plate 610 into the bottom limit shell 604. The extrusion push plate 610 contacts the outermost punching die mechanism 8, thereby completing the fixation of multiple punching die mechanisms 8. The rotating limit plate 608 is an L-shaped structure. The extrusion push plate 610 is slidably connected to the bottom limit shell 604. The L-shaped structure of the rotating limit plate 608 ensures that the extrusion push plate 610 can be accommodated inside the rotating limit plate 608, and thus will not affect the rotation and opening of the rotating limit plate 608. At the same time, the extrusion push plate 610 is slidably connected to the bottom limit shell 604, ensuring that the extrusion push plate 610 can be completely fitted with the punching die mechanism 8.

[0042] like Figure 1-Figure 13As shown, one side of the connecting mechanism 6 is slidably connected with a plurality of ejection mechanisms 7, and the ejection mechanism 7 includes an adjusting threaded rod 701 slidably connected to the side extension support rod 605, the outer wall of the adjusting threaded rod 701 is fixedly connected with a U-shaped limiting plate 702, one side of the rear end surface of the U-shaped limiting plate 702 is fixedly connected with a side pointer 703, the bottom of the adjusting threaded rod 701 is fixedly connected with a bottom ejection block 704, and the top of the adjusting threaded rod 701 is spirally connected with a second nut seat 705. Before use, the plurality of adjusting threaded rods 701 are moved according to the shape and size of the insole. The position of the threaded rod 701 is adjusted so that it is directly above the corresponding insole, and then the second nut seat 705 is used to complete the locking and fixing. When the connecting mechanism 6 descends, the bottom ejecting blocks 704 in the multiple ejecting mechanisms 7 will be driven to descend, and then the molded insole 4 that appeared in the previous punching process will be ejected and fall on the top of the movable support plate 206. At the same time, when moving the position of the adjusting threaded rod 701, the position between each two adjusting threaded rods 701 can be determined by the cooperation of the side pointer 703 and the scale 606 according to the width of the punching die mechanism 8, thereby improving the adjustment speed.

[0043] like Figure 1-Figure 15 As shown, the bottom of the connecting mechanism 6 is slidably connected to a plurality of punching die mechanisms 8, and the punching die mechanisms 8 include a die shell 801 slidably connected to the inner wall of the bottom limit shell 604, the bottom of the die shell 801 is fixedly connected to two punching tools 802, the rear end of the die shell 801 is fixedly connected to a locking convex plate 803, the bottom of the die shell 801 is slidably connected to two sliding sleeve shells 804 corresponding to the punching tools 802, the top inner surface of the die shell 801 is fixedly connected to two groups of mounting pads 805, and the two groups of mounting pads 805 and the corresponding two sliding sleeve shells 804 are fixedly connected. When the reset spring 806 is in use, as the overall connecting mechanism 6 moves downward, it will drive multiple punching die mechanisms 8 until the sliding shell 804 contacts the insole plate 3 and then continues to descend. At this time, the sliding shell 804 stops moving and begins to compress multiple reset springs 806 until the punching tool 802 contacts the insole plate 3 and then goes deeper to complete the punching. During the resetting process, the punching tool 802 leaves the insole plate 3. Under the action of the reset spring 806, the sliding shell 804 always fits the insole plate 3 to avoid the situation where the cut molded insole 4 is stuck inside the punching tool 802.

[0044] The working principle of this embodiment is as follows: before use, the corresponding punching die mechanism 8 is selected according to the size and model of the punching insole; the two punching tools 802 in a single punching die mechanism 8 are of a centrally symmetrical structure, thereby being able to save materials to the greatest extent; during installation, the bolt assembly 611 is disassembled, the locking threaded rod 609 is rotated to pull the extrusion push plate 610 to disengage it from the bottom limit shell 604, and then the rotating limit plate 608 is rotated to open, and the punching die mechanism 8 is slidably installed according to the structure inside the bottom limit shell 604; multiple die shells 801 are fitted together and are engaged with each other through the engaging convex plate 803, until the maximum number is added, and then the rotating limit plate 608 is rotated to reset. , and then fix it through the bolt assembly 611, and finally rotate the locking threaded rod 609 to push the extrusion push plate 610 into the inner wall of the bottom limiting shell 604, until the extrusion push plate 610 contacts the outermost mold shell 801, thereby completing the fixation of multiple blanking mold mechanisms 8, and at the same time, according to the shape and size of the insole, slide multiple limiting rods 203 so that they can roughly limit the formed insole 4 to avoid offset and tipping during the stacking process, and at the same time rotate the first nut seat 205 to fix the limiting rod 203. Similarly, move the positions of the multiple adjusting threaded rods 701 so that they are directly above the corresponding insoles, and then complete the locking and fixing through the second nut seat 705;

[0045] When in use, the insole plate 3 is placed on the top of the workbench 1, and then the insole plate 3 is pushed manually or mechanically so that its end is at the bottom of the multiple punching die mechanisms 8, and then the driving motor 508 is started to drive the driving pinion 509 to rotate, and drive the transmission gear 503 meshing therewith, so that the rotating crankshaft 502 is rotated between the two side support plates 501. During the rotation of the rotating crankshaft 502, it will drive multiple rotating connecting blocks 601, and then drive multiple connecting sleeves 603 to rotate through the corresponding first fixed rotating shaft 602. The connecting mechanism 6 moves up and down, and the position is limited by the connecting plate 505. When the whole connecting mechanism 6 moves downward, it will drive multiple blanking die mechanisms 8 until the sliding shell 804 contacts the insole plate 3, and then continues to descend. At this time, the sliding shell 804 stops moving and starts to compress multiple reset springs 806 until the blanking tool 802 contacts the insole plate 3 and then deeply completes the blanking. During the reset process, the blanking tool 802 leaves the insole plate 3. Under the action of the reset spring 806, the sliding shell 804 always fits the insole plate 3.

[0046] After completing one stamping, continue to pull the insole plate 3 to the next stamping position, and then continue to repeat the stamping. At the same time, when the connecting mechanism 6 descends, it will drive multiple ejection mechanisms 7 to descend, and then eject the molded insole 4 that appeared in the previous punching process, so that it falls on the top of the movable support plate 206. In the process of repeated work, the molded insole 4 will be continuously accumulated. Since the descending position of the bottom top block 704 is fixed, when the thickness of the accumulated molded insole 4 is large, the movable support plate 206 will be pushed by squeezing the molded insole 4. The movable support plate 206 will descend and squeeze the limiting rack 210 through the limiting extension plates 207 at both ends, and then squeeze the arc-shaped metal spring piece 209. When the arc-shaped metal spring piece 209 continuously generates a reaction force, the limiting extension plate 207 will be squeezed downward for a short distance, and the limiting extension plate 207 will be re-engaged with the limiting rack 210, and under the limitation of multiple limiting rods 203, the stacking of the insoles is automatically completed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.

the bottom of the adjusting threaded rod (701) is fixedly connected to a bottom ejecting block (704); and the top of the adjusting threaded rod (701) is spirally connected to a second nut seat (705); The punching die mechanism (8) comprises a die shell (801) slidably connected to the inner wall of the bottom limit shell (604); two punching tools (802) are fixedly connected to the bottom of the die shell (801); a locking convex plate (803) is fixedly connected to the rear end of the die shell (801); two sliding sleeves (804) corresponding to the punching tools (802) are slidably connected to the bottom of the die shell (801); two groups of mounting pads (805) are fixedly connected to the inner surface of the top of the die shell (801); and a return spring (806) is fixedly connected between the two groups of mounting pads (805) and the corresponding two sliding sleeves (804); When in use, the insole plate (3) is placed on the top of the workbench (1), and then the insole plate (3) is pushed manually or mechanically so that its end is at the bottom of the plurality of punching die mechanisms (8), and then the driving motor (508) is started to drive the driving pinion (509) to rotate, and drive the transmission gear (503) meshing therewith, so that the rotating crankshaft (502) is rotated between the two side support plates (501). During the rotation of the rotating crankshaft (502), the plurality of rotating connecting blocks (601) are driven, and then the plurality of connecting sleeves (603) are driven through the corresponding first fixed rotating shaft (602) to rotate. The upward and downward reciprocating motion is completed through the connection plate (505). During the downward movement of the overall connection mechanism (6), the plurality of blanking die mechanisms (8) are driven until the sliding shell (804) contacts the insole plate (3) and then continues to descend. At this time, the sliding shell (804) stops moving and starts to compress the plurality of return springs (806) until the blanking tool (802) contacts the insole plate (3) and then the blanking is completed. During the resetting process, the blanking tool (802) leaves the insole plate (3). Under the action of the return spring (806), the sliding shell (804) always fits the insole plate (3). After completing one punching operation, the insole plate (3) is continuously pulled to the next punching position, and then the punching operation is repeated. At the same time, when the connecting mechanism (6) descends, multiple ejection mechanisms (7) are driven to descend, thereby ejecting the formed insole (4) produced in the previous punching process, causing it to fall on the top of the movable support plate (206). During the repeated operation, the formed insole (4) is continuously accumulated. Since the descending position of the bottom top block (704) is fixed, when the accumulated formed insole (4) is thick, the formed insole (4) is squeezed and formed. The movable support plate (206) is pushed by the pad (4), and the movable support plate (206) is lowered and squeezes the limit rack (210) through the limit extension plates (207) at both ends, thereby squeezing the arc-shaped metal spring sheet (209). When the arc-shaped metal spring sheet (209) continuously generates a reaction force, the limit extension plate (207) is squeezed downward for a short distance, and the limit extension plate (207) is re-engaged with the limit rack (210), and the insoles are automatically stacked under the limit of multiple limit rods (203).
