Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, and in particular to an automatic cutting device for shoemaking sheet materials. Background Technology

[0002] Shoes are items worn on the feet to protect them and facilitate walking, and are typically made of materials such as leather, cloth, and rubber. The production of shoes requires cutting the fabric, necessitating the use of specialized automated cutting equipment.

[0003] Existing automatic cutting devices for shoemaking fabric typically involve placing the fabric on a cutting table and then cutting it using a specific shaped cutting tool, as exemplified by a shoemaking mold with patent publication number CN210190320U. Because it's difficult to ensure the fabric remains flat after placement, and the device lacks an integrated structure to smooth out wrinkles, the cutting process is affected, thus reducing shoe quality. Therefore, we provide an automatic cutting device for shoemaking fabric. Utility Model Content

[0004] To address the problem in the aforementioned background technology that the difficulty in ensuring the flatness of the fabric leads to a reduction in the quality of fabric cutting, this utility model provides an automatic cutting device for shoemaking sheet materials.

[0005] This utility model is achieved by the following technical solution: an automatic cutting device for shoemaking sheet material, including a base and an anti-wrinkle component. A placement platform is fixedly connected to the top of the base, and a bracket is also fixedly connected to the base. A hydraulic cylinder is fixedly connected to the bracket, and a pressure plate is fixedly connected to the telescopic end of the hydraulic cylinder.

[0006] The anti-wrinkle assembly includes four sets of L-shaped fixing frames symmetrically fixedly connected to the pressure plate. Movable rods are hinged to the L-shaped fixing frames via hinges. A leveling roller is rotatably connected between the ends of two sets of movable rods on the same side. A sliding rod is also fixedly connected to the L-shaped fixing frame via a connecting seat. A slider is slidably connected to the outside of the sliding rod. Two sets of connecting rods are symmetrically hinged between the slider and the movable rod on the same side via hinges. A spring is also sleeved on the outside of the sliding rod.

[0007] As a further improvement to the above solution, a push plate is provided below the pressure plate, and two sets of vertical rods are symmetrically fixedly connected to the top of the push plate and are slidably connected to the pressure plate. A fixing plate is fixedly connected to the top of the vertical rods, and a spring is sleeved on the outside of the vertical rods.

[0008] As a further improvement to the above solution, a cutting tool is fixedly connected to the bottom of the pressure plate, and a cutting groove adapted to the cutting tool is opened on the top of the placement platform at the position corresponding to the cutting tool.

[0009] As a further improvement to the above solution, the length of the leveling roller is matched with the width of the placement table.

[0010] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the connecting seat and the slider, respectively.

[0011] As a further improvement to the above solution, the two ends of the second spring are fixedly connected to the fixing plate and the pressure plate, respectively.

[0012] As a further improvement to the above scheme, the two sets of leveling rollers are arranged in a mirror-symmetrical manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the cutting blade at the bottom of the pressure plate is moved downward by the hydraulic cylinder, the two sets of leveling rollers are also moved downward together. When the leveling rollers first come into contact with the fabric on the placement table, as the pressure plate continues to move downward, and with the hinge between the movable rod and the L-shaped fixed frame, the rotation between the leveling rollers and the movable rod, the sliding between the slider and the sliding rod, and the hinge between the slider, the movable rod and the connecting rod, the two sets of leveling rollers will roll towards both sides simultaneously, thereby automatically straightening and leveling the fabric, thus preventing wrinkles from affecting the quality of shoemaking. It is highly practical.

[0015] 2. When the hydraulic cylinder drives the cutting tool at the bottom of the pressure plate to rise and reset, it can also drive the two sets of fixed plates to rise together. When the fixed plates contact the bracket, as the pressure plate continues to rise, the push plate can automatically push out the shoe fabric stuck on the inner side of the cutting tool, thereby facilitating the removal of the shoe fabric and further improving the practicality of the device.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1:

[0023] Please combine Figure 1-3 An automatic cutting device for shoe-making sheet material according to this embodiment includes a base 1, a placement platform 2 fixedly connected to the top of the base 1, a bracket fixedly connected to the base 1, a hydraulic cylinder 3 fixedly connected to the bracket, a pressure plate 4 fixedly connected to the telescopic end of the hydraulic cylinder 3, a cutting blade 5 fixedly connected to the bottom of the pressure plate 4, and a cutting groove 6 adapted to the position of the cutting blade 5 on the top of the placement platform 2, which can automatically cut the fabric into the shape of the desired shoe.

[0024] An anti-wrinkle assembly for automatically straightening and smoothing fabric includes four sets of L-shaped fixing frames 101 symmetrically fixed to the pressure plate 4. Movable rods 102 are hinged to the L-shaped fixing frames 101 via hinges. A leveling roller 103 is rotatably connected between the ends of two sets of movable rods 102 on the same side. The two sets of leveling rollers 103 are mirror-symmetrically arranged. A slide rod 104 is also fixedly connected to the L-shaped fixing frame 101 via a connecting seat. A slider 105 is slidably connected to the outside of the slide rod 104. Two sets of connecting rods 106 are symmetrically hinged between the slider 105 and the movable rod 102 on the same side via hinges. A spring 107 is also sleeved on the outside of the slide rod 104. The two ends of the spring 107 are fixedly connected to the connecting seat and the slider 105, respectively.

[0025] A push plate 201 is provided below the pressure plate 4. The push plate 201 is located on the inner side of the cutting tool 5. Two sets of vertical rods 202 are symmetrically fixedly connected to the top of the push plate 201 and the vertical rods 202 are slidably connected to the pressure plate 4. A fixing plate 203 is fixedly connected to the top of the vertical rods 202. A second spring 204 is sleeved on the outside of the vertical rods 202. The two ends of the second spring 204 are fixedly connected to the fixing plate 203 and the pressure plate 4 respectively.

[0026] The implementation principle of the automatic cutting device for shoemaking sheet material in this embodiment is as follows: First, the fabric is spread on the placement table 2. Then, the hydraulic cylinder 3 is activated. When the cutting blade 5 at the bottom of the pressure plate 4 is moved downward by the hydraulic cylinder 3, it also drives two sets of leveling rollers 103 to move downward together. When the leveling rollers 103 first come into contact with the fabric on the placement table 2, as the pressure plate 4 continues to move downward, and with the hinge between the movable rod 102 and the L-shaped fixed frame 101, the rotational engagement between the leveling rollers 103 and the movable rod 102, the sliding engagement between the slider 105 and the sliding rod 104, and the hinge engagement between the slider 105, the movable rod 102, and the connecting rod 106, the two sets of leveling rollers 103 will roll simultaneously to both sides, thereby automatically straightening and leveling the fabric and preventing wrinkles. If the quality of the shoe is affected, spring 107 will be compressed. As the pressure plate 4 descends, the cutting tool 5 will penetrate into the cutting groove 6 to cut the fabric. Then, the hydraulic cylinder 3 will be activated to drive the cutting tool 5 to rise and reset. When the hydraulic cylinder 3 drives the cutting tool 5 at the bottom of the pressure plate 4 to rise and reset, it will also drive the two sets of fixing plates 203 to rise together. When the fixing plate 203 contacts the bracket, as the pressure plate 4 continues to rise, the push plate 201 can automatically push out the fabric stuck on the inner side of the cutting tool 5, so as to facilitate the removal of the fabric. At this time, spring 204 will be compressed. Conversely, when the pressure plate 4 moves vertically downward, the push plate 201 can automatically reset by the rebound of spring 204. The reset push plate 201 will not affect the cutting of the fabric. Finally, the cut fabric can be removed.

[0027] Example 2:

[0028] This embodiment is an improvement on embodiment 1, in that the length of the leveling roller 103 is matched with the width of the placement table 2, which can improve the leveling effect on the fabric.
