[0020] 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.

[0021] Example

[0022] Please see Figures 1-4 The diagram shows a PU artificial leather three-dimensional embossing device, including a processing support frame 1. A motor 2 is housed inside the processing support frame 1. A cooling device 3 for supplying cold air to the embossing steel roller is located on one side of the motor 2. A guide roller shaft 4 is located above the motor 2. A cooling pipe 5 is connected to the cooling device 3. A lower embossing steel roller 6 is located above the cooling device 3. One end of the cooling pipe 5 is rotatably connected to a hollow shaft 7. Bearings 8 are rotatably connected to both ends of the hollow shaft 7. The hollow shaft 7 is fixedly connected to an upper embossing steel roller 9 with a smooth surface. Bearings 8 are fixedly connected to bearing brackets 10. Bearing brackets 10 are fixedly connected to... The support plate 11 is equipped with an adjustment mechanism 12 for easy installation of the embossing template. The upper embossing steel roller 9 is fixedly connected to the embossing template 13. The support plate 11 is fixedly connected to the telescopic ends of two telescopic cylinders 14, which are connected to the upper embossing steel roller through a hollow shaft. The upper embossing steel roller is fixedly connected to the embossing template. The embossing template works in conjunction with the adjustment mechanism, which includes an auxiliary pulley, a sliding rod, a main pulley, a main traction rope, a secondary traction rope, a locking rod, a limit block, a locking block, a spring, and a template limit frame. This enables quick replacement of the embossing template while reducing the labor intensity of the workers.

[0023] Furthermore, the hollow shaft 7 is hollow inside and has an air outlet. Through the air outlet of the hollow shaft, the cooling effect of the cooling device can be quickly transmitted to the embossing template, ensuring the stability of the embossing.

[0024] Furthermore, the embossing template 13 is divided into a left template 1301 and a right template 1302. The left template 1301 is inserted into the right template 1302. The embossing template 13 is fixedly connected to the upper embossing steel roller 9 by screws. The embossing template is divided into a left template and a right template. Each template needs to be connected to the upper embossing steel roller on both sides by screws to ensure the stability of the embossing template.

[0025] Furthermore, the adjustment mechanism 12 includes an auxiliary pulley 1201, a slide bar 1202, a main pulley 1203, a main traction rope 1204, a secondary traction rope 1205, a locking rod 1206, a limit block 1207, a locking block 1208, a spring 1209, and a template limiting frame 1210. The slide bar 1202 is fixedly connected to the inside of the support plate 11, and the slide bar 1202 is slidably connected to the template limiting frame 1210. The slide bar 1202 is fitted with a spring 1209. Through the adjustment mechanism including the auxiliary pulley, slide bar, main pulley, main traction rope, secondary traction rope, locking rod, limit block, locking block, spring, and template limiting frame, the embossing template can be quickly changed while reducing the labor intensity of the workers.

[0026] Furthermore, the template limiting frame 1210 is fixedly connected to one end of the main traction rope 1204, and the spring 1209 is tightly pressed on one side of the template limiting frame 1210. The main traction rope 1204 is slidably connected to the auxiliary pulley 1201, and one end of the main traction rope 1204 is fixedly connected to the secondary traction rope 1205. Since the main traction rope has three connecting ends, it can simultaneously connect two template limiting frames and the secondary traction rope, thereby ensuring the synchronicity of the movement of the two template limiting frames.

[0027] Furthermore, the traction auxiliary rope 1205 is slidably connected to the main pulley 1203, and one end of the locking rod 1206 is fixedly connected to the traction auxiliary rope 1205. The locking rod 1206 is slidably connected to the limiting block 1207, and the locking rod 1206 is engaged with the locking block 1208. The locking block 1208 and the limiting block 1207 are fixedly connected to the top of the support plate 11. Through the locking rod, the locking block, and the limiting block, the traction auxiliary rope can be effectively pulled to move, thereby ensuring the stability of the locking rod movement and the convenience of locking.

[0028] In this solution, the workflow is as follows: Motor 2 is installed inside the support frame and drives the guide roller shaft 4 and the lower embossing steel roller 6 to rotate synchronously through the transmission mechanism, providing basic power for the embossing process.

[0029] The upper embossed steel roller 9 forms a rotating unit through the hollow shaft 7 and the bearing 8. The hollow shaft has a cold air channel inside and air outlet holes distributed on its surface to realize the synchronous transmission of cold air and rotational power.

[0030] The cooling device 3 is connected to the end of the hollow shaft 7 via the cooling pipe 5, and delivers low-temperature cold air to the inside of the embossing steel roller. The cold air diffuses evenly to the roller surface through the air outlet of the hollow shaft, maintaining the material temperature stability during the embossing process and preventing the pattern accuracy from being affected by heat deformation.

[0031] The upper embossing steel roller 9 has a fixed split embossing template 13, which is composed of a left template 1301 and a right template 1302 connected by an interlocking structure and can be quickly assembled and disassembled by screws. This design supports personalized changes of template patterns to meet diverse embossing needs.

[0032] Simultaneously, the telescopic cylinder 14 is used to adjust the distance between the upper and lower rollers, controlling the embossing depth and material tension.

[0033] The adjustment mechanism 12 uses the slide bar 1202 as a track, and the template limiting frame 1210 achieves elastic reset through the spring 1209. During operation, the main traction rope 1204 drives the limiting frame to slide through the auxiliary pulley 1201, fixing the template in a horizontal position; the secondary traction rope 1205 is linked to the locking rod 1206 through the main pulley 1203, causing it to slide within the limiting block 1207 and engage with the locking block 1208 to form a mechanical lock.
