Abstract
Description
Technical Field
[0001] This utility model relates to the field of footwear cutting technology, specifically a footwear cutting machine. Background Technology
[0002] A shoe cutting machine is a device used to cut shoe materials. It primarily cuts materials needed for shoe making, such as leather and fabric, into pre-designed shapes and sizes. For example, it cuts a whole piece of leather into the shapes of the upper and other parts of the shoe. It improves cutting precision, is more efficient than hand cutting, and produces cleaner edges, which helps improve the quality and speed of shoe production.
[0003] When cutting the shoes, a large piece of leather is first laid on the machine table, and then the cutting assembly cuts it according to the shoe shape. When the cutting is completed, there will be a lot of leftover leather that needs to be cleaned. Because the leather pieces are too large, currently two workers are required to lift and place them to the storage area during cleaning. The excessive weight of stacked leather makes it too heavy to lift, and the required labor cost is also relatively high.
[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a cutting machine for footwear manufacturing. Utility Model Content
[0005] In view of the shortcomings of the above-mentioned background technology, this utility model provides a technical solution for a cutting machine for footwear manufacturing, which solves the problems mentioned in the background technology.
[0006] This utility model provides the following technical solution: a footwear cutting machine, including a workbench, base I fixed on both sides of the workbench, a sliding frame slidably mounted on the top of the base I, and a cutting assembly for cutting fixed on one side of the sliding frame;
[0007] The base I has a pressure rod slidably connected inside by a slider. A rotating sleeve is fixed to the top of the slider. A connecting sleeve is snapped onto the surface of the rotating sleeve. A support block is slidably snapped onto the top of the connecting sleeve. A collar II is fixed to the top of the support block. The two ends of the pressure rod are supported and fixed inside the collar II by the collar II.
[0008] The connecting sleeve has a retaining block I inside, and the rotating sleeve has multiple circumferentially distributed retaining grooves II on its surface. The retaining block I engages with the rotating sleeve surface through the retaining grooves II, and a lifting block is connected to one side of the support block through a fixed shaft.
[0009] As a preferred technical solution of this utility model, the lifting block is a lifting structure, and a collar I is fixed on the top of the lifting block. The collar I and collar II are of equal height. The collar I is sleeved on the outside of the pressure rod, and a clamping rod is fixed at the bottom of the collar I.
[0010] As a preferred technical solution of this utility model, a lead screw passes through the middle of the fixed shaft, and a circumferentially distributed slot is provided at the bottom of the lead screw. A base II is fixed to the top of the base I, and a rotating seat is rotatably connected to the top of the base II.
[0011] As a preferred technical solution of this utility model, the base II and the rotating seat are engaged and cannot be disassembled or removed. The top of the rotating seat is provided with multiple circumferentially distributed slots I, and the number of slots I corresponds to the number of slots at the bottom of the lead screw.
[0012] As a preferred technical solution of this utility model, the slot I is slidably connected with the insert block II, the insert block II is inserted into the slot at the bottom of the lead screw, the collar II and the pressure rod surface are both fixedly connected with hinge blocks, the outer walls of the collar I and collar II are fixed with the insert block II, and one outer surface is elastically connected with a sliding push rod.
[0013] As a preferred embodiment of this utility model, the push rod is externally fixed with a plug block I, which is inserted into the lower surface of the locking block II.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Rotating the rotating sleeve will offset the slot II from the block I, preventing the block I from being ejected due to inertia and remaining stuck in the slot II. Then, flipping the entire pressure bar and clamping bar will quickly roll up the stacked remaining leather for processing, eliminating the need for manual lifting and cleaning of large pieces of leather, which is physically demanding.
[0016] 2. The rotating seat drives the lead screw to rotate simultaneously. The rotation of the lead screw drives the fixed shaft, lifting block, support block and pressure bar to rise and fall simultaneously. The height of the pressure bar can be adjusted according to the thickness of the leather being laid, so that the pressure bar clamps the end of the leather, and provides auxiliary clamping to maintain the stability of the leather during cutting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 As shown, the shoe-making cutting machine includes a workbench 1, base I4 fixed on both sides of the workbench 1, a sliding frame 2 slidably mounted on the top of the base I4, and a cutting assembly 3 for cutting fixed on one side of the sliding frame 2.
[0025] Inside the base I4, a pressure rod 401 is slidably connected via a slider 402. A rotating sleeve 4081 is rotatably connected to the top of the slider 402. A connecting sleeve 4082 is snapped onto the surface of the rotating sleeve 4081. A support block 408 is slidably snapped onto the top of the connecting sleeve 4082. A collar II 409 is fixed to the top of the support block 408. Both ends of the pressure rod 401 are supported and fixed inside the collar II 409 through the collar II 409.
[0026] The connecting sleeve 4082 has a retaining block I 40821 elastically connected inside. The rotating sleeve 4081 has multiple circumferentially distributed retaining grooves II on its surface. The retaining block I 40821 is engaged with the surface of the rotating sleeve 4081 through the retaining grooves II. One side of the support block 408 is connected to a lifting block 405 through a fixed shaft 407.
[0027] The lifting block 405 is a lifting structure. A collar I 404 is fixed to the top of the lifting block 405. The collar I 404 and the collar II 409 are of equal height. The collar I 404 is sleeved on the outside of the pressure rod 401. A clamping rod 403 is fixed to the bottom of the collar I 404. A lead screw 406 passes through the middle of the fixed shaft 407. The bottom of the lead screw 406 has circumferentially distributed slots. The top of the base I 4 is fixed to the base II 410. The top of the base II 410 is rotatably connected to the rotating seat 4103. The base II 410 and the rotating seat 4103 are interlocked and cannot be disassembled or removed. The top of the rotating seat 4103 has multiple circumferentially distributed slots I 4101. The number of slots I 4101 corresponds to the number of slots at the bottom of the lead screw 406.
[0028] The slot I 4101 is slidably connected to the insert block II 4102, which is inserted into the slot at the bottom of the lead screw 406. The collar II 409 and the pressure rod 401 are both fixedly connected to the hinge block. The outer wall of the collar I 404 and the collar II 409 is fixed with the block II 411, and one of the outer surfaces is elastically connected to the sliding push rod 412. The push rod 412 is fixed to the outside with the insert block I 4121, which is inserted into the lower surface of the block II 411.
[0029] When cutting out shoes, the shape of the sole must first be cut out, and then the upper is made. During the cutting of the sole shape, a large sheet of leather is laid out, and multiple sole shapes can be cut at once. When laying the leather, the ends of the leather are placed over the clamping rod 403, and then the layers are laid out. The insert block II 4102 is then inserted into the slot at the bottom of the lead screw 406. Rotating the rotating seat 4103 causes the lead screw 406 to rotate simultaneously. The rotation of the lead screw 406 causes the fixed shaft 407, lifting block 405, support block 408, and pressure rod 401 to rise and fall simultaneously. The height of the pressure rod 401 can be adjusted according to the observed thickness of the laid leather. The pressure bar 401 clamps the end of the leather, providing auxiliary clamping to maintain the stability of the leather during cutting. When the leather is cut, the insert block II 4102 can be pushed out into the slot at the bottom of the lead screw 406. Then, the sliding block I 40821 is slid up so that the connecting sleeve 4082 is not engaged with the rotating sleeve 4081. Then, the rotating sleeve 4081 is rotated to displace the slot II and the block I 40821, preventing the block I 40821 from being ejected due to inertia and continuing to be stuck in the slot II. Then, the entire pressure bar 401 and clamping bar 403 are flipped over, which can quickly roll up the stacked remaining leather for processing, eliminating the need for manual lifting and cleaning of large sheets of leather, which is physically demanding.
[0030] When the two ends of the pressure rod 401 are fitted inside the collar I 404 and collar II 409, first open the upper part of collar II 409 and collar I 404, then place the pressure rod 401 inside the collar I 404 and collar II 409. Then, when the upper part of collar I 404 and collar II 409 flips to close, the locking block II 411 is inserted into the lower part of collar I 404 and collar II 409. Then, pull the push rod 412 so that the insert block I 4121 is inserted into the locking block II 411. When the upper and lower parts of collar I 404 and collar II 409 are closed, they are fixed, and the two ends of the pressure rod 401 are stably fitted and installed to avoid the phenomenon of breaking open when the leather is rolled up later due to too much leather.
