[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified appearance that makes it less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, with a special grain layer on its surface, giving it a natural grain and luster, and a comfortable feel. During production and processing, leather is often embossed using a embossing machine to enhance its appearance.

[0003] Currently, when embossing machines are working, they usually press the texture of the outer wall of the leather embossing roller onto the leather surface by rotating the roller. When pressing different textures, the leather embossing roller needs to be replaced. However, the current method of replacing the leather embossing roller is quite cumbersome and the entire replacement process takes a lot of time, which needs to be improved. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The leather embossing machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] like Figure 1-8As shown, a leather embossing machine includes a leather embossing roller 1 and two mounting frames 2. The leather embossing roller 1 is located above the two mounting frames 2. An abutment roller 4 is located below the leather embossing roller 1. An abutment position adjustment mechanism 3 is located below the two mounting frames 2. The abutment position adjustment mechanism 3 includes a support plate 31, a positioning plate 36, and a support frame 37. The two ends of the abutment roller 4 are rotatably connected to the inside of the support frame 37. The two sides of the support plate 31 and the positioning plate 36 are fixedly connected between the two mounting frames 2. 6 is located above the support plate 31. A second self-locking motor 32 is fixedly installed in the middle of the bottom of the support plate 31. The output end of the second self-locking motor 32 extends to the top of the support plate 31 and is fixedly connected to a second lead screw 33. The top end of the second lead screw 33 is rotatably installed in the middle of the bottom of the positioning plate 36. A connecting plate 34 is threadedly connected to the outer wall of the second lead screw 33. Multiple push rods 35 are fixedly connected to the top of the connecting plate 34. The outer walls of the multiple push rods 35 are all slidably sleeved inside the positioning plate 36. The top end of the push rod 35 is fixedly connected to the bottom of the support frame 37.

[0026] In this embodiment, the second self-locking motor 32 facilitates the rotation of the second lead screw 33. The second lead screw 33, through the connecting plate 34, drives the top rod 35 to slide vertically in the internal vertical groove of the positioning plate 36. The positioning plate 36 facilitates the vertical guidance of the top rod 35. The top rod 35 then drives the support frame 37 to move the abutment roller 4, adjusting the distance between the abutment roller 4 and the leather embossing roller 1, thereby enabling embossing processing of leather of different thicknesses.

[0027] Example 2:

[0028] like Figure 1-8As shown, each of the two mounting brackets 2 has a limiting groove 21 in the middle of its top. A rotating shaft 11 is fixedly connected inside the leather embossing roller 1. Two bearings 12 are symmetrically mounted on the outer wall of the rotating shaft 11. The outer wall of the bearings 12 is located inside the limiting groove 21. A fixing frame 24 is fixedly mounted on one side of the top of each of the two mounting brackets 2. A pressure plate 27 is slidably connected inside one side of the fixing frame 24. A connecting rod 29 is fixedly connected to one side of the bottom of the pressure plate 27. An arc-shaped limiting plate 291 is fixedly connected to the bottom end of the connecting rod 29. The inner wall of the arc-shaped limiting plate 291 overlaps the top of the bearing 12. A connecting gear 13 is fixedly mounted on one end of the rotating shaft 11. One side of one mounting bracket 2 has an upper... A drive motor 22 is fixedly installed on the fixed frame 24. A drive gear 23 is fixedly installed on the output end of the drive motor 22. The drive gear 23 is located below the connecting gear 13 and meshes with the connecting gear 13. A self-locking motor 25 is fixedly installed on the top of the fixed frame 24. The output end of the self-locking motor 25 extends into the interior of the fixed frame 24 and a lead screw 26 is fixedly installed thereon. The bottom end of the lead screw 26 is rotatably connected to the bottom of the inner wall of the fixed frame 24. The internal thread of the pressure plate 27 on the other side is connected to the outer wall of the lead screw 26. Guide rods 28 are fixedly connected to both sides of the inner wall of the fixed frame 24. The interior of the pressure plate 27 is slidably sleeved on the outer wall of the guide rods 28.

[0029] In this embodiment, the drive motor 22 and drive gear 23 work together to drive the connecting gear 13 to rotate. The connecting gear 13 drives the rotating shaft 11 to rotate inside the bearing 12. The rotating shaft 11 rotates at the same time, so that the leather embossing roller 1 can press the texture onto the surface of the leather. The setting of the limiting groove 21 and the arc-shaped limiting plate 291 facilitates the limiting of the bearing 12. The cooperation of the first self-locking motor 25 and the first lead screw 26 facilitates the movement of the pressure plate 27. The setting of the guide rod 28 facilitates the vertical guidance of the pressure plate 27. The pressure plate 27 drives the arc-shaped limiting plate 291 to move out of the limiting groove 21 and up to the top of the mounting frame 2 through the connecting rod 29. At this time, the leather embossing roller 1, rotating shaft 11, bearing 12 and connecting gear 13 can be disassembled to facilitate the replacement of the leather embossing roller 1, rotating shaft 11, bearing 12 and connecting gear 13.

[0030] In summary, as Figure 1-8As shown, this leather embossing machine, when in use, drives the second lead screw 33 to rotate through the output end of the second self-locking motor 32. The second lead screw 33 drives the top rod 35 to slide vertically in the groove inside the positioning plate 36 through the connecting plate 34. The top rod 35 drives the support frame 37 to move the contact roller 4, thereby adjusting the distance between the contact roller 4 and the leather embossing roller 1. When pressing the texture, one end of the leather is placed between the contact roller 4 and the leather embossing roller 1. The output end of the drive motor 22 drives the drive gear 23 to rotate. The drive gear 23 drives the rotating shaft 11 to rotate inside the bearing 12 through the connecting gear 13. The rotating shaft 11 rotates the leather embossing roller 1, thereby pressing the texture onto the surface of the leather using the leather embossing roller 1.

[0031] When replacing the leather embossing roller 1 with a different texture, the first self-locking motor 25 at the top of the two fixed frames 24 drives the first lead screw 26 to rotate. The first lead screw 26 drives the pressure plate 27 to slide vertically on the outer wall of the guide rod 28. The pressure plate 27, through the connecting rod 29, drives the arc-shaped limiting plate 291 to move upward, so that the arc-shaped limiting plate 291 disengages from the limiting groove 21 and moves upward to the top of the mounting frame 2. At this time, the leather embossing roller 1 can be retrieved. The leather embossing roller 1, along with the rotating shaft 11 and bearing 12, moves out of the limiting groove 21, allowing the leather embossing roller 1, rotating shaft 11, bearing 12, and connecting gear 13 to be disassembled. The new leather embossing roller 1 is placed above the two mounting brackets 2. The leather embossing roller 1 drives the bearing 12 to move into the limiting groove 21 through the rotating shaft 11. The limiting groove 21 is used to initially limit the bearing 12. The leather embossing roller 1 drives the connecting gear 13 to move above the driving gear 23 through the rotating shaft 11, and makes the connecting gear 13 mesh with the driving gear 23. At this time, the output end of the first self-locking motor 25 drives the first lead screw 26 to rotate in the opposite direction, and drives the arc-shaped limiting plate 291 to press down on the top of the bearing 12 in the same way, thus limiting the bearing 12 and installing the leather embossing roller 1.
