Description

Technical Field

[0001] This utility model relates to the field of leather embossing machine technology, and in particular to a leather embossing machine that is easy to replace the embossing plate. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, and is therefore less prone to decay. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and a comfortable feel. As living standards improve, people have higher and higher requirements for leather processing, and embossing machines are used to process the surface of leather with the patterns that people want.

[0003] The announcement number CN219670532U discloses a leather embossing machine that facilitates the replacement of embossing plates. This device, by setting up a leather embossing machine that facilitates the replacement of embossing plates, can automatically and quickly fix the embossing plates and can adjust according to the size of the embossing plates. This not only saves the tedious steps of manual replacement by workers, but also makes the clamping more stable after replacement, thereby improving production efficiency.

[0004] However, during use, the L-shaped clamping claws only achieve planar clamping through bidirectional screw drive, lacking vertical limiting constraints. When the device is processing, it is easy to cause the embossing plate to warp slightly, resulting in uneven pattern depth. Therefore, this utility model proposes a leather embossing machine that facilitates the replacement of embossing plates to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a leather embossing machine that facilitates the replacement of embossing plates. This solves the problem in the prior art where the L-shaped clamping claws only achieve planar clamping through bidirectional screw drive, lacking vertical limiting constraints. When the device is processing, the embossing plate is prone to slight upward warping, resulting in uneven pattern depth.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a leather embossing machine that facilitates the replacement of embossing plates, including a processing table, a moving mechanism fixedly installed at the bottom of the processing table near the center, a placement seat fixedly installed on the top of the moving mechanism, a fixing frame fixedly installed on the top of the processing table and located to the right of the placement seat, a cylinder fixedly installed on the top of the fixing frame, the power output shaft of the cylinder passing through the inner side of the fixing frame and fixedly installed on a mounting seat, an embossing component provided at the bottom of the mounting seat for different processing needs, and an adjustment component provided inside the mounting seat for installing different embossing components.

[0007] A further improvement is that the adjustment component includes a first bevel gear, the right end of which is rotatably connected to the inner wall of the mounting base. Second bevel gears are meshed on the front and rear sides of the first bevel gear. A lead screw is fixedly mounted on the surface of the second bevel gear. A movable frame is sleeved on the surface of the lead screw and threadedly connected to it. A first sliding groove is provided on the inner side of the mounting base, allowing the movable frame to slide back and forth. A drive motor for driving the first bevel gear to rotate is fixedly mounted on the right side of the mounting base.

[0008] A further improvement is that: a threaded rod is rotatably connected to the inner side of the movable frame near the left and right sides; a threaded block is fitted on the surface of the threaded rod and threadedly connected to it; a positioning rod is fixedly installed on the side of the threaded block away from the threaded rod; a knob for driving the threaded rod to rotate is rotatably connected to the surface of the movable frame; and a second sliding groove is provided on the inner side of the movable frame for the threaded block to move left and right.

[0009] A further improvement is that: two mounting plates are slidably connected to the bottom of the mounting base; multiple first positioning holes adapted to the positioning rod are opened on the inner side of the mounting plate near the left and right sides; a fixing block is fixedly installed on the bottom of the mounting base near the front and rear sides; and an electric telescopic rod for driving the mounting plate to slide back and forth is fixedly installed on the surface of the fixing block.

[0010] A further improvement is that the embossing component includes a mounting frame, a locking seat is engaged inside the mounting frame, an embossing board body is fixedly mounted at the bottom of the locking seat, a first mounting opening and a second mounting opening are provided inside the mounting frame to match the locking seat and the embossing board body, and a second positioning hole is provided at an adjacent location inside the mounting frame and the locking seat.

[0011] A further improvement is that: a notch is provided on the inner side of the fixing frame and on both sides of the mounting base, and the front and rear sides of the mounting base are slidably connected to the inner sidewall of the fixing frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. During replacement, the drive motor drives the bevel gear and lead screw to slide the movable frame and release the limit on the embossing component. The operator can remove the old embossing component without disassembling complicated bolts. The new embossing component is quickly positioned by the locking structure between the locking seat and the mounting frame. Then, the spacing of the mounting plate is adjusted by the electric telescopic rod, and the position of the positioning rod is finely adjusted by the knob. Finally, the positioning rod is fixed by the cooperation of the positioning hole. The whole process does not rely on special tools and can flexibly adjust the clamping structure according to the size of different embossing boards without changing the matching fixture. This effectively reduces the operation steps and time of embossing board replacement and meets diverse processing needs.

[0014] 2. When fixing the embossing component, the adjusting component forms a double constraint on the embossing component from both horizontal and vertical directions through the rigid connection between the positioning rod and the positioning hole, and the fit between the top of the locking seat and the bottom of the mounting seat, reducing the slight displacement and upward warping of the embossing plate during the embossing process.

[0021] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-5 As shown, this embodiment proposes a solution: a leather embossing machine that facilitates the replacement of embossing plates, including a processing table 1, a moving mechanism 2 fixedly installed at the bottom of the processing table 1 near the center, a placement seat 3 fixedly installed on the top of the moving mechanism 2, a fixing frame 4 fixedly installed on the top of the processing table 1 and to the right of the placement seat 3, a cylinder 5 fixedly installed on the top of the fixing frame 4, the power output shaft of the cylinder 5 passing through the inside of the fixing frame 4 and a mounting seat 6 fixedly installed, an embossing component provided at the bottom of the mounting seat 6 for different processing needs, and an adjustment component provided inside the mounting seat 6 for installing different embossing components.

[0023] In this implementation case, when the equipment is started, the moving mechanism 2 receives a control signal and drives the fixedly connected placement seat 3 at the top to move horizontally. The placement seat 3 is used to carry the leather to be processed. It can accurately transport the leather to the bottom of the embossing component according to the requirements of the embossing process, or remove the leather from the processing area after processing. When the embossing process is started, the cylinder 5 receives a pneumatic signal and drives the output shaft to move synchronously with the vertical extension mounting seat 6, which drives the embossing component at the bottom to press the leather down. By adjusting the component, it can ensure both fast replacement efficiency and the stability of the embossing component, avoiding uneven pattern depth.

[0024] The adjustment assembly includes a first bevel gear 7, the right end of which is rotatably connected to the inner wall of the mounting base 6. Second bevel gears 8 are meshed on the front and rear sides of the first bevel gear 7. A lead screw 9 is fixedly mounted on the surface of the second bevel gear 8, and a movable frame 10 is sleeved on the surface of the lead screw 9 and threadedly connected to it. A first sliding groove is provided on the inner side of the mounting base 6, allowing the movable frame 10 to slide back and forth. A drive motor 11 is fixedly mounted on the right side of the mounting base 6 to drive the first bevel gear 7 to rotate. When the drive motor 11 starts working, it drives the first bevel gear 7 to rotate, causing the second bevel gears 8 meshing on the front and rear sides to rotate synchronously in the opposite direction. Because the lead screw 9 is threadedly connected to the movable frame 10, and the movable frame 10 is limited by the first sliding groove on the inner side of the mounting base 6, the rotation of the lead screw 9 is converted into the back-and-forth sliding of the movable frame 10, thereby releasing the limiting effect on the embossing assembly.

[0025] A threaded rod 12 is rotatably connected to the inner side of the movable frame 10 near the left and right sides. A threaded block 13 is fitted onto the surface of the threaded rod 12 and threadedly connected to it. A positioning rod 14 is fixedly installed on the side of the threaded block 13 away from the threaded rod 12. A knob 15 is rotatably connected to the surface of the movable frame 10 to drive the threaded rod 12 to rotate. A second sliding groove is opened on the inner side of the movable frame 10 to allow the threaded block 13 to move left and right. Based on the size of the embossing assembly, the operator rotates the knob 15 to drive the threaded rod 12 to rotate, thereby causing the threaded block 13 to slide left and right to the appropriate position inside the second sliding groove, so that the positioning rod 14 moves to the appropriate position.

[0026] Two mounting plates 16 are slidably connected to the bottom of the mounting base 6. Multiple first positioning holes 17 adapted to the positioning rods 14 are opened on the inner side of the mounting plates 16 near the left and right sides. Fixed blocks are fixedly installed on the bottom of the mounting base 6 near the front and rear sides. Electric telescopic rods 18 that drive the mounting plates 16 to slide back and forth are fixedly installed on the surface of the fixed blocks. According to the width of the embossing component, the electric telescopic rods 18 start to work, driving the two mounting plates 16 to slide in the same direction, so that the distance between the mounting plates 16 is adjusted to a suitable distance. In conjunction with the first positioning holes 17 and the positioning rods 14, the mounting plates 16 and the embossing component are limited.

[0027] The embossing assembly includes a mounting frame 19, with a locking seat 20 engaged inside the mounting frame 19. An embossing board body 21 is fixedly mounted on the bottom of the locking seat 20. The mounting frame 19 has a first mounting opening and a second mounting opening that are adapted to the locking seat 20 and the embossing board body 21. A second positioning hole 22 is provided at an adjacent position on the inner side of the mounting frame 19 and the locking seat 20. The locking seat 20 is engaged and fixed with the mounting frame 19 through the first mounting opening, and the embossing board body 21 is connected to the mounting frame 19 through the second mounting opening, so that the embossing assembly is engaged between two mounting plates 16. At the same time, the top of the locking seat 20 is attached to the bottom of the mounting seat 6, increasing the stability of the embossing board body 21 during operation.

[0028] The fixing frame 4 has notches on its inner side and on both sides of the mounting base 6. The front and rear sides of the mounting base 6 are slidably connected to the inner wall of the fixing frame 4. The notches allow the adjustment components to work normally.

[0029] The above embodiment discloses a leather embossing machine that facilitates the replacement of embossing plates. When the machine is started, the moving mechanism 2 receives a control signal, driving the fixedly connected placement seat 3 at the top to move horizontally. The placement seat 3 carries the leather to be processed. The drive motor 11 starts working, driving the first bevel gear 7 to rotate, which in turn drives the second bevel gears 8 meshing on the front and rear sides to rotate synchronously in opposite directions. Since the lead screw 9 is threadedly connected to the movable frame 10, and the movable frame 10 is limited by the first sliding groove inside the mounting seat 6, the rotation of the lead screw 9 is converted into the forward and backward sliding of the movable frame 10, thereby releasing the limiting effect on the embossing component. According to the requirements of the embossing process, a suitable embossing component can be taken out. The locking seat 20 is locked and fixed to the mounting frame 19 through the first mounting port. The embossing plate body 21 is connected to the mounting frame 19 through the second mounting port, so that the embossing component is locked between the two mounting plates 16. The working... The operator rotates knob 15, causing threaded rod 12 to rotate, thereby causing threaded block 13 to slide left and right to the appropriate position inside the second sliding groove, and positioning rod 14 to move to the appropriate position. Electric telescopic rod 18 starts working, driving two mounting plates 16 to slide in the same direction, so that the inner sidewall of mounting plate 16 is attached to the left and right sides of mounting frame 19. Drive motor 11 drives first bevel gear 7 to rotate in the opposite direction, so that positioning rod 14 is inserted into the inner side of adjacent first positioning hole 17 and second positioning hole 22, limiting the mounting plate 16 and embossing assembly. At the same time, the top of locking seat 20 is attached to the bottom of mounting seat 6, increasing the stability of embossing plate body 21 during operation, or removing leather from the processing area after processing. When the embossing process starts, cylinder 5 receives air pressure signal and drives output shaft to telescopically move mounting seat 6 in the vertical direction, driving the bottom embossing assembly to press down on the leather, completing the device processing process.
