Description

Technical Field

[0001] This utility model relates to the field of shoe sole repair technology, specifically a shoe sole molding edge repair device. Background Technology

[0002] The construction of shoe soles is quite complex. In a broad sense, it can include all the materials that make up the bottom, such as the outsole, midsole, and heel. Different materials result in significant differences in the comfort, waterproofness, and abrasion resistance of the finished shoe sole.

[0003] Because the processing of shoe soles requires multiple processes to be stacked into a whole, and multiple materials need to be stacked and molded under high temperature and high pressure, when the shoe sole is exposed to the environment after molding and loses temperature rapidly, the sides of the shoe sole will warp due to the shrinkage of excess material. In severe cases, this can cause the shoe sole to be uneven or deformed. Existing shoe sole repair requires workers and cutters to cut off the excess material, which is extremely inefficient and poses certain safety hazards to workers.

[0004] In view of this, a device for trimming the curled edges of the sole after molding was designed to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a device for trimming the curled edges of shoe soles after molding. Example

[0032] Combination Figures 1 to 5As shown, this utility model provides a shoe sole molding edge trimming device. It includes a molded shoe sole 100, a shoe sole calibration mechanism 200 mounted on a workbench and supporting the molded shoe sole 100, and an edge pressing and punching mechanism 300 mounted on the shoe sole calibration mechanism 200 and used to finely trim the molded shoe sole 100. The shoe sole calibration mechanism 200 provides a support platform for rapid calibration of the molded shoe sole 100. The edge pressing and punching mechanism 300, in conjunction with the shoe sole calibration mechanism 200, performs full compression on the molded shoe sole 100 and punches away the extruded waste material from the molded shoe sole 100.

[0033] The sole calibration mechanism 200 includes a sole plate 210, a bottom pad 220 fixedly installed on the top of the sole plate 210, and a bottom support pad 230 fixedly installed on the top of the sole plate 210 and located inside the bottom pad 220.

[0034] The sole calibration mechanism 200 also includes two telescopic rods 2501, a calibration buckle 2403 attached to the front side of the bottom support pad 230, two brackets 240 fixedly installed on the top of the bottom pad 220, a guide rod 2401 movably installed inside the brackets 240, and a first spring 2402 set outside the guide rod 2401 and pressed on the brackets 240, a bottom clamp 250 installed in the bottom plate 210 and the bottom pad 220, and a top clamp 2505 installed in the top plate 310 and the top pad 320, with the two telescopic rods 2501 respectively installed in the bottom clamp 250 and the top clamp 2505, two covers 2502 movably installed outside the two telescopic rods 2501, a combination bolt 2504 installed in the two covers 2502, and two second springs 2503 set inside the two covers 2502;

[0035] The internal thread section of the guide rod 2401 is adapted to be installed in the threaded sleeve on the outer wall of the calibration buckle 2403;

[0036] The top of the inner side of the calibration buckle 2403 is provided with a bevel that is adapted to the bottom cutting edge of the punching tool 330;

[0037] The edge-pressing and punching mechanism 300 includes a top plate 310 located directly above the bottom pad 220, a top pad 320 mounted on the top of the top plate 310, a punching cutter 330 movably mounted in the top plate 310 and the top pad 320, two second end plates 3402 mounted on the top pad 320, and a top load-bearing pad 350 mounted on the inner ends of the two second end plates 3402 and located inside the punching cutter 330.

[0038] A slot is provided between the base plate 210 and the bottom support pad 230 to fit the bottom cutting edge of the punching tool 330.

[0039] In the initial state, the lower half of the calibration buckle 2403 is fitted to the side of the front end of the bottom support pad 230, while the upper half of the calibration buckle 2403 is located directly above the bottom support pad 230. When the molded sole 100 is quickly assembled along the gap between the bottom support pad 230 and the top support pad 350, the molded sole 100, which is under the pressure of the calibration buckle 2403, will quickly fit with the top surface of the bottom support pad 230.

[0040] As the external stamping device pushes the punching cutter 330 downwards, the downward pressure on the punching cutter 330 will help push the top support pad 350 closer to the molded sole 100. The top support pad 350 will first bear the pressure on the molded sole 100. With the continuous compression of the molded sole 100 by the top support pad 350 and the bottom support pad 230, the waste material on the side of the molded sole 100 will be squeezed outwards. The continuously descending punching cutter 330 will effectively punch the waste material on the side of the molded sole 100 along the outer wall of the top support pad 350 and the bottom support pad 230. Example

[0041] Combination Figure 5 As shown, based on Embodiment 1, the edge-pressing and punching mechanism 300 further includes a vertical rod 3401 fixedly installed inside the second end plate 3402, a third spring 3403 disposed outside the vertical rod 3401, and a first end plate 340 fixedly installed in the slide groove, and the top end of the vertical rod 3401 is adapted to penetrate into the first end plate 340.

[0042] The second end plate 3402 is internally fitted with a fixing bolt 3404, which is fixedly installed inside the top load-bearing pad 350.

[0043] The punching tool 330 has grooves at both the front and rear ends, and the second end plate 3402 extends through the grooves.

[0044] Corrugated transverse grooves are provided on the top of the bottom support pad 230 and the bottom of the top support pad 350. The thickness of the top support pad 350 is twice the thickness of the bottom support pad 230.

[0045] Preferably, the two vertical rods 3401 are adapted to extend through the outside of the punching tool 330. When the punching tool 330 is pressed and falls downward, the two vertical rods 3401 provide stabilizing guidance for the lifting and lowering of the punching tool 330. Therefore, the pressure of the front and rear ends of the punching tool 330 contacting the top of the molded shoe sole 100 can be kept constant, thereby improving the accuracy of the punching tool 330 in punching the molded shoe sole 100 when it is squeezed and overflows with waste.

[0046] The working principle and usage process of this utility model: When it is necessary to trim the molded shoe sole 100, the bottom plate 210 is placed on the workbench in advance. At this time, a large gap will be reserved between the edge pressing and punching mechanism 300 and the shoe sole calibration mechanism 200. Then, the molded shoe sole 100 after molding is sent into the top of the bottom support pad 230 along the gap.

[0047] The front end of the molded sole 100 will be pressed against the inside of the calibration buckle 2403. Since the groove on the inside of the calibration buckle 2403 is aligned with the top of the bottom support pad 230, the molded sole 100 will be quickly aligned with the bottom support pad 230 after being placed.

[0048] Next, an external stamping device is used to apply a downward impact force to the punching cutter 330. As the punching cutter 330 continues to descend, the two first end plates 340 and the two third springs 3403 installed in the punching cutter 330 will push the top plate 310 and the top support pad 350 to quickly move closer to the top of the molded shoe sole 100. The bottom of the top support pad 350 will press against the top of the molded shoe sole 100 first. At this time, the molded shoe sole 100 will be quickly calibrated and clamped by the bottom support pad 230 and the top support pad 350.

[0049] When the molded sole 100 is continuously pressed and clamped by the bottom support pad 230 and the top support pad 350, the punching cutter 330, which continues to descend along the inner side of the top plate 310, will effectively punch the waste material that is squeezed and overflows from the side of the molded sole 100. Therefore, this device can improve the efficiency of punching the edge of the molded sole 100 without damaging the overall thickness and structure of the molded sole 100.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
