[0031] Combine the following Figures 1 to 4 The embodiments of the present utility model are described.

[0032] The present embodiment relates to a leather embossing machine, which realizes embossing with dynamic depth.

[0033] The leather embossing machine comprises: a frame (not shown in the figure), a driving motor 1, a plate pressing roller 2, a leather roller 3, a pushing and clamping mechanism, and a pitch changing mechanism;

[0034] The driving motor 1 is arranged on the frame, and the driving motor 1 is drivingly connected to the plate pressing roller 2;

[0035] The push-clamp mechanism comprises a slide rail 41, a push-clamp structure 42, a spring 43, and a movable shaft block 44. The slide rail 41 is fixed on the frame, the movable shaft block 44 slides along the slide rail 41, the leather roller 3 is rotatably arranged on the movable shaft block 44, one end of the spring 43 is fixed on the push-clamp structure 42, and the push-clamp structure 42 is used to push the spring 43 toward the movable shaft block 44, so that the movable shaft block 44 has a tendency to move toward the plate-pressing roller 2;

[0036] The pitch changing mechanism includes a diameter-changing wheel 51 , the distance from the center to the outer circumference of the diameter-changing wheel 51 is different, the diameter-changing wheel 51 is rotatably arranged on the frame, the diameter-changing wheel 51 is transmission-connected with the plate-pressing roller 2 , and the end of the movable shaft block 44 facing away from the spring 43 abuts against the diameter-changing wheel 51 .

[0037] The leather embossing machine is equipped with a push-clamp mechanism and a variable-distance mechanism to replace the existing adjustment structure. The push-clamp mechanism realizes the dynamic change of the embossing depth, thereby expanding the function of the leather embossing machine.

[0038] Specifically, before the leather is loaded, the pushing and clamping structure 42 is in a position where the movable shaft block 44 is not pushed tightly, so that the leather can enter between the leather roller 3 and the plate pressing roller 2 of the movable shaft block 44. After the leather enters between the leather roller 3 and the plate pressing roller 2, the pushing and clamping structure 42 pushes the spring 43 to move toward the movable shaft block 44, so that the movable shaft block 44 on which the leather roller 3 is installed pushes tightly toward the plate pressing roller 2, clamping the leather for embossing; at the same time, the movable shaft block 44 is pushed tightly by the spring 43, and the movable shaft block 44 abuts against the reducing wheel 51, which is transmission-connected with the plate pressing roller 2, that is, the reducing wheel 51 rotates together with the plate pressing roller 2. Since the outer diameters of the reducing wheel 51 are different, during the rotation of the reducing wheel 51, the reducing wheel 51 will push the movable shaft block 44 to compress the spring 43 and slide along the slide rail 41, dynamically changing the position of the movable shaft block 44, thereby dynamically changing the embossing depth of the plate pressing roller 2, processing embossing with dynamically changing depth, and realizing the functional expansion of the leather embossing machine.

[0039] The pitch changing mechanism further includes an extension arm 52, which is disposed on the movable shaft block 44, and the extension arm 52 is disposed on a side of the movable shaft block 44 adjacent to the diameter-changing wheel 51, and the movable shaft block 44 abuts against the diameter-changing wheel 51 through the extension arm 52. The movable shaft block 44 abuts against the diameter-changing wheel 51 through the extension arm 52, so that the spatial position setting of the movable shaft block 44 and the diameter-changing wheel 51 has greater flexibility, which is conducive to simplifying the installation design.

[0040] The pitch changing mechanism further includes a roller 53, which is located at one end of the extension arm 52 adjacent to the diameter-changing wheel 51. The roller 53 is rotatably arranged on the extension arm 52, and the extension arm 52 abuts against the diameter-changing wheel 51 through the roller 53. When the diameter-changing wheel 51 rotates, the extension arm 52 slides relative to the diameter-changing wheel 51. By arranging the roller 53 and allowing the extension arm 52 to abut against the diameter-changing wheel 51 through the roller 53, the sliding resistance between the extension arm 52 and the diameter-changing wheel 51 can be reduced.

[0041] The variable diameter wheel 51 is detachably connected to the frame, so that the variable diameter wheel 51 can be replaced as needed to achieve embossing at different dynamic depths.

[0042] The pitch changing mechanism also includes a variable diameter shaft 54 ​​and a transmission belt 55. The variable diameter shaft 54 ​​is located between the movable shaft block 44 and the plate pressing roller 2. The variable diameter shaft 54 ​​is rotatably set on the frame. The plate pressing roller 2 is connected to the variable diameter shaft 54 ​​through a belt drive. The variable diameter wheel 51 is detachably mounted on the variable diameter shaft 54. The projection of the variable diameter wheel 51 along the axial direction of the variable diameter shaft 54 ​​falls outside the plate pressing roller 2.

[0043] The variable diameter shaft 54 ​​is connected to the platen roller 2 by a transmission belt 55, so that the variable diameter shaft 54 ​​can be arranged outside the platen roller 2. The projection of the variable diameter wheel 51 along the axis direction of the variable diameter shaft 54 ​​falls outside the platen roller 2, so when the variable diameter wheel 51 is disassembled, it can be directly slid out along the variable diameter shaft 54, and the disassembly is relatively convenient. Specifically, the driving motor 1 includes a motor shaft, which is connected to the platen roller 2 by a transmission, and the motor shaft is also connected to the variable diameter shaft 54 ​​by a belt, and the platen roller 2 and the variable diameter shaft 54 ​​are connected by the motor shaft in turn.

[0044] The pitch changing mechanism further includes a limiting gasket 541 and a shaft cover 56, wherein the limiting gasket 541 is fixed on the reducing shaft 54, the shaft cover 56 is detachably connected to the reducing shaft 54, and the reducing wheel 51 is limited between the limiting gasket 541 and the shaft cover 56. The setting of the limiting gasket 541 and the shaft cover 56 limits the axial position of the reducing wheel 51 on the reducing shaft 54, and better ensures that the reducing wheel 51 can maintain contact with the roller 53.

[0045] The limiting gasket 541 is integrally formed with the reducing shaft 54. The limiting gasket 541 is integrally formed and arranged on the reducing shaft 54, which is beneficial to reducing costs and simplifying the structure. In this embodiment, the shaft cover 56 can be detachably connected to the reducing shaft 54 ​​by screw connection.

[0046] The push-clamp structure 42 is a cylinder. The push-clamp structure 42 adopts a cylinder, which has the advantage of low cost.

[0047] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
