In the early days, people used them to overcome special situations and prevent their feet from feeling uncomfortable or injured. Now, shoes of various styles and functions can be seen everywhere. Most shoes have lace holes, and holes need to be punched during the production process.

[0003] A shoelace hole positioning punching device for upper processing is disclosed in the Chinese patent application publication specification CN218303682U. When the device is in use, the spacing of the punching columns can be adjusted by starting the adjustment motor. The operation is simple and the adjustment is convenient, so that the device can be applied to punching holes in various uppers.

[0004] Although the spacing of the punching columns can be adjusted in the solution of the above patent, the number of punching columns of the punching device in the above patent is fixed. When the number of holes in the shoes needs to be changed, the punching equipment needs to be stopped and replaced, which is inconvenient to control the number of punching column operations required for shoe punching. For this reason, we provide a punching device for shoelace holes to solve the above problems. Utility Model Content

[0029] In the above scheme, the compression spring 114 provides elastic support for the transmission block 113, so that the punching rod 7 can move upward. When punching holes in the shoe upper, the punching rod 7 higher than the bottom surface of the lifting plate 2 does not perform the hole punching operation.

[0030] The power mechanism 11 includes a power block 111 fixed on the top surface of the support frame 5 . An eccentric wheel 112 is fixedly sleeved on the output end of the power block 111 . The periphery of the eccentric wheel 112 slides on the top surface of the transmission block 113 .

[0031] In the above scheme, the power block 111 is started by external power, and the eccentric wheel 112 is rotated above the support frame 5 by the power block 111, and the transmission block 113 is slid on the top surface of the support frame 5 by the eccentric wheel 112, and drives the punching rod 7 to move downward, so that the height difference between the punching rod 7 and the lifting plate 2 can be adjusted, and the shoe upper can be perforated by the punching rod 7 which is lower than the height of the lifting plate 2.

[0032] Please refer to Figure 1 and Figure 2 A limiting mechanism 8 for limiting the position of the punching rod 7 is arranged on the outside of the lifting plate 2.

[0033] Please refer to Figure 3 The limiting mechanism 8 includes a positioning frame 81 sliding on the outside of the moving frame 3, the inner side wall of the positioning frame 81 is fixed to one side of the lifting plate 2, and a moving groove 82 is opened on the top surface of the positioning frame 81. The inside of the moving groove 82 is slidably connected to a slider 83 sleeved on the periphery of the punching rod 7.

[0034] In the ascending scheme, through the cooperation between the positioning frame 81 and the slider 83, the punching rod 7 can be moved horizontally along the direction of the moving groove 82 during adjustment, so as to facilitate the adjustment of the working distance between the punching rods 7.

[0035] Please refer to Figure 1 and Figure 2 A connecting plate 9 is fixed to the top surface of the fixed frame 1, a hydraulic rod 10 is fixed to the bottom surface of the connecting plate 9, the bottom end of the hydraulic rod 10 is fixed to the upper surface of the lifting plate 2, and a transmission mechanism 12 for driving the moving frame 3 to slide is provided on the top surface of the lifting plate 2.

[0036] In the above solution, the lifting plate 2 is driven downward by the hydraulic rod 10 , and the punching rod 7 , which is lower than the height of the lifting plate 2 , is used to perform a hole punching operation on the shoe upper.

[0037] Please refer to Figure 4 The transmission mechanism 12 includes a support block 121 fixed on the upper surface of the lifting plate 2, and a bidirectional threaded rod 122 is rotatably sleeved inside the support block 121. Both ends of the bidirectional threaded rod 122 are provided with threads in opposite directions, and one end of the bidirectional threaded rod 122 is fixedly sleeved with a rocker 123.

[0038] The transmission mechanism 12 also includes two limit frames 124 fixed on the top surface of the lifting plate 2, and the two limit frames 124 are slidably connected to the inside of the moving blocks 125. The insides of the two moving blocks 125 are respectively threadedly connected to the two ends of the bidirectional threaded rod 122, and one side of each moving block 125 is rotatably connected to a connecting rod 126, and the end of each connecting rod 126 away from the moving block 125 is rotatably connected to a connecting block 127, and the two connecting blocks 127 are fixed to one side of the moving frame 3.

[0039] In the above scheme, by rotating the rocker 123 with external force and through the cooperation between the rocker 123 and the bidirectional threaded rod 122, the two moving blocks 125 can move towards or away from each other, and through the cooperation between the moving blocks 125, the connecting rod 126 and the connecting block 127, the moving frame 3 can slide horizontally on the top surface of the lifting plate 2.

[0040] Working principle: When the punching device is in use, the rocker 123 is rotated by external force, and the cooperation between the rocker 123 and the bidirectional threaded rod 122 can make the two moving blocks 125 approach or move away from the supporting block 121 at the same time. The cooperation between the moving block 125, the connecting rod 126 and the connecting block 127 can make the moving frame 3 slide horizontally on the top surface of the lifting plate 2. At the same time, through the slide grooves 4 at different angles inside the moving frame 3, the punching rods 7 inside the slide grooves 4 are made to approach or move away from each other. Through the cooperation between the positioning frame 81 and the slider 83, the punching rods 7 can be moved horizontally along the direction of the moving grooves 82 during adjustment, so as to facilitate the adjustment of the working distance between the punching rods 7. The power block 111 is started by external power. The eccentric wheel 112 is rotated above the support frame 5 through the power block 111, and the transmission block 113 is slid on the top surface of the support frame 5 through the eccentric wheel 112, and drives the punching rod 7 to move downward, so as to adjust the height difference between the punching rod 7 and the lifting plate 2, and then the lifting plate 2 is driven downward by the hydraulic rod 10, and the punching rod 7 below the height of the lifting plate 2 is used to perform hole drilling operation on the shoe upper. When the power block 111 controls the eccentric wheel 112 to rotate in the opposite direction, the compression spring 114 is used to provide elastic support for the transmission block 113, so that the punching rod 7 can move upward. When the shoe upper is drilled again, the punching rod 7 above the bottom surface of the lifting plate 2 does not perform hole drilling operation, which is convenient for adjustment according to the requirements of different numbers of holes in the shoe upper.
