[0020] This utility model provides a soft PU leather embossing device.

[0021] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The pressure plate 1 includes two convex grooves 2 at its bottom. A convex rod 3 is slidably connected in the convex groove 2. A template 4 is fixedly connected between the two convex rods 3. A pin groove 5 is formed on the opposite side of the two convex grooves 2. A pin 6 is slidably connected in the pin groove 5. Two springs are provided between one end of the pin 6 and the end of the pin groove 5. A pull groove 12 is provided on one side of the pressure plate 1. A connecting groove 13 is connected through the pull groove 12 and the pin groove 5. A pull rod 7 is slidably connected in the pull groove 12. A pull rope 8 is fixedly connected to one end of each pin 6. The pull rope 8 is located in the connecting groove 13. A through pin hole 9 is provided at the corresponding position of the convex rod 3 relative to the pin 6. Specifically, template 4 is used for imprinting patterns or textures. Template 4 is existing technology equipment, and its specific imprinting method, specific shape, and connection method are all existing technologies, which will not be described in detail in this application. A heating tube or other device for heating template 4 can be installed in pressure plate 1. The heating-related structure and usage are all existing technologies, which will not be described in detail in this application. The vertical cross-section of convex groove 2 is an inverted convex cavity, and the vertical cross-section of convex rod 3 is an inverted convex structure. The main components such as pressure plate 1, convex rod 3, and template 4 are made of high-strength aluminum alloy, which has good wear resistance and corrosion resistance, while also reducing the weight of the device and facilitating operation. The pin 6 and pull rod 7 are made of stainless steel to ensure sufficient strength and durability. Specifically, a clearance fit is used between the inner wall of the convex groove 2 and the outer surface of the convex rod 3 to ensure smooth sliding of the convex rod 3. Simultaneously, guide strips can be provided on the inner wall of the convex groove 2, and guide grooves that cooperate with them can be provided on the convex rod 3 to further improve the stability and accuracy of sliding. The sliding groove 51 in the pin groove 5 and the sliding plate 62 of the pin 6 are fitted with a clearance. The sliding plate 62 is slidably connected to the stabilizing rod 10 through a stabilizing hole, ensuring that the pin 6 slides stably in the sliding groove 51. The elastic force of the spring is designed to be moderate, which ensures that the pin 6 can slide smoothly, and provides sufficient preload in the non-operating state to prevent the pin 6 from loosening.

[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The pin 6 includes a triangular pin head 61, the horizontal cross section of which is a right triangle structure, and a sliding plate 62 is fixedly connected to one end of the triangular pin head 61. The pin groove 5 includes a sliding groove 51, and a through opening 52 is provided between the sliding groove 51 and the convex groove 2. The triangular pin head 61 is slidably connected inside the through opening 52, and the sliding plate 62 is slidably connected inside the sliding groove 51.

[0023] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5Two stabilizing rods 10 are fixedly connected to the inner wall of the sliding groove 51. The two stabilizing rods 10 are located on both sides of the triangular pin head 61. The sliding plate 62 has through-holes at the corresponding positions of the two stabilizing rods 10. The stabilizing rods 10 are slidably connected inside the stabilizing holes. Two springs are slidably sleeved on the outside of the two stabilizing rods 10.

[0024] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 A stabilizing groove 11 is formed on the inner wall of the convex groove 2 away from the pin groove 5, and the stabilizing groove 11 is adapted to the sharp corner of the triangular pin head 61.

[0025] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The pull groove 12 includes a square groove 121 formed in the pressure plate 1. A cylindrical groove 122 is provided on one side of the pressure plate 1, which passes through the square groove 121. The pull rod 7 is slidably connected inside the cylindrical groove 122. One side of the square groove 121 is connected to the connecting groove 13. Two rotating wheels 15 are rotatably connected on the inner wall of the square groove 121. The outer wall of the rotating wheels 15 is in contact with the side wall of the pull rope 8.

[0026] Please see Figure 1 A hydraulic telescopic rod 16 is installed on the top of the pressure plate 1. A U-shaped frame 17 is installed at the top of the hydraulic telescopic rod 16. A worktable 18 is fixedly connected to the bottom of the U-shaped frame 17. The worktable 18 is located below the pressure plate 1.

[0027] Please see Figure 1 A guide rod 14 is fixedly connected between the bottom wall inside the U-shaped frame 17 and the worktable 18. A through guide hole is opened at the corresponding position of the pressure plate 1 relative to the guide rod 14, and the guide rod 14 is slidably connected in the guide hole. Specifically, a guide plate or clamping and fixing device can be set on the workbench 18 to place or fix the position of the soft PU leather, so as to ensure the accuracy and consistency of the embossed pattern. Since the guide plate or clamping and fixing device are existing technical structures or equipment, their specific forms, usage methods and installation methods are existing technical means, and this application will not elaborate on them.

[0028] Please see Figure 2 and Figure 3 Two rotating grooves are provided at one end of the convex rod 3, and a pulley 19 is rotatably connected in the rotating groove. The side wall of the pulley 19 is in contact with the inclined surface of the triangular pin head 61. Specifically, the contact between the pulley 19 and the inclined surface of the triangular pin head 61 can reduce the friction between the two, allowing the pin 6 to slide more smoothly.

[0029] Working principle: When installing template 4, first insert the convex rod 3 into the convex groove 2 at the bottom of the pressure plate 1; the pulley 19 on the convex rod 3 will contact the inclined surface of the triangular pin head 61 and squeeze it, so that the triangular pin head 61 slides completely into the pin groove 5, and at the same time compresses the spring. Therefore, the installation of template 4 can be completed without manually pulling the pull rod 7; after the convex rod 3 is fully inserted into the convex groove 2, the triangular pin head 61 is partially ejected from the pin groove 5 by the elastic force of the spring, and the triangular pin head 61 is inserted into the corresponding pin hole 9, and the tip of the triangular pin head 61 passes through the pin hole 9 and is inserted into the corresponding stabilizing groove 11.

[0030] When disassembling template 4, by pulling the pull rod 7, the pull rod 7 drives the pin 6 to slide in the pin groove 5 through the pull rope 8, so that the triangular pin head 61 is disengaged from the pin hole 9. At this time, the convex rod 3 and template 4 can be easily removed from the convex groove 2 at the bottom of the pressure plate 1, and the disassembly of template 4 is completed.

[0031] Embossing process: Place the soft PU leather on the workbench 18; the hydraulic telescopic rod 16 drives the pressure plate 1 to move downward, and the template 4 at the bottom of the pressure plate 1 contacts the soft PU leather and applies pressure, thereby imprinting the desired pattern or texture on the surface of the soft PU leather; during the embossing process, the guide rod 14 is slidably connected to the guide hole on the pressure plate 1, which plays a guiding and stabilizing role, ensuring that the pressure plate 1 can move up and down smoothly and ensuring the embossing quality.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
