Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically a leather embossing device for leather processing. Background Technology

[0002] In the leather processing industry, embossing is an important means of enhancing the appearance and added value of leather. Through the pressure of the upper and lower plates or rollers of a straight-plate embossing machine, delicate textures can be formed on the leather surface. However, existing straight-plate embossing equipment has significant drawbacks, hindering the development of the leather processing industry.

[0003] Most existing equipment has only one workstation, with the pressure plate vertically positioned directly above the leather placement area. This structural design poses a significant safety hazard: due to the small distance between the upper and lower pressure plates and the enormous pressure, workers can easily lose their hands in the pressure plate's working area when placing leather, adjusting its position, or removing finished products, leading to crushing accidents and seriously threatening the workers' personal safety.

[0004] Meanwhile, the existing equipment has low embossing efficiency: after leather is embossed, it needs to go through a cooling and shaping process, but the equipment has not been optimized for the cooling process and can only passively wait for the leather to cool naturally. This process takes a long time and significantly extends the overall processing cycle. Therefore, developing a leather embossing device for leather processing that is safe, has high embossing efficiency, and can effectively solve the problems of single-station operation and cooling time has become a key issue that the industry urgently needs to solve.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Example 1

[0025] Please see Figure 1-6 , a leather embossing device for leather processing, comprising a base 1, on which a support frame 2 is fixedly arranged. An embossing module 3 is installed inside the support frame 2. A box body 4 is also fixedly arranged on the base 1. A first carrier plate 5 and a second carrier plate 6 are arranged on the box body 4. Heating grooves are arranged on both the first carrier plate 5 and the second carrier plate 6. The first carrier plate 5 is movably arranged on the top surface of the box body 4, and the second carrier plate 6 is movably arranged in the box body 4 and is in clearance fit with the inner wall of the box body 4. A driving mechanism for driving the first carrier plate 5 and the second carrier plate 6 to alternately move below the embossing module 3 is also arranged inside the box body 4. The driving mechanism includes a linear driving component, a movable plate 7, a fixed plate 11, a connecting plate 9, a round rod 8 and a driving rod 10. The movable plate 7 is movably arranged inside the box body 4 and is located below the second carrier plate 6. Four round rods 8 are also movably installed on the movable plate 7. The second carrier plate 6 is fixedly arranged at the top ends of the round rods 8. A pair of connecting plates 9 are fixedly arranged in parallel at the bottom ends of the round rods 8. A driving rod 10 is installed between the two connecting plates 9. The fixed plate 11 is fixedly installed inside the box body 4, and a strip-shaped hole 12 slidably adapted to the driving rod 10 is formed on the fixed plate 11. The strip-shaped hole 12 is in a "ji" - shaped structure. The linear driving component is used to provide power for the relative movement of the movable plate 7 and the first carrier plate 5. By driving the relative movement of the movable plate 7 and the first carrier plate 5 through the linear driving component, under the action of the round rods 8, the second carrier plate 6 and the connecting plate 9 move along with the movable plate 7. The driving rod 10 slides in the "ji" - shaped strip-shaped hole 12 of the fixed plate 11, so that the heights of the first carrier plate 5 and the second carrier plate 6 are staggered, and they successively move below the embossing module 3. The operator can place the leather on the carrier plate staggered from the embossing module 3, avoiding the hand entering the dangerous area, and solving the safety hazard problem of single-station operation.

[0026] It should be noted that the embossing module 3 in this embodiment is an existing module component, so it will not be elaborated in this embodiment.

[0027] Among them, there are two fixed plates 11, and the two fixed plates 11 are arranged in parallel between the two connecting plates 9. A roller 13 is also rotatably installed on the rod body of the driving rod 10 located inside the strip-shaped hole 12. The setting of the roller 13 can reduce the friction between the driving rod 10 and the inner wall of the strip-shaped hole 12, make the driving rod 10 slide more smoothly in the strip-shaped hole 12, ensure the stability and reliability of the alternating movement of the first carrier plate 5 and the second carrier plate 6, and extend the service life of the equipment.

[0028] Specifically, the linear drive assembly includes a lead screw 14 rotatably disposed within the housing 4 and a guide rod 16 mounted in parallel on one side of the lead screw 14. A nut 15 adapted to the lead screw is installed on the lead screw, and a sliding sleeve 17 is slidably disposed on the guide rod 16. The first bearing plate 5 and the movable plate 7 are fixedly mounted on the nut 15 and the sliding sleeve 17. This linear drive assembly has a simple structure and precise transmission, and can provide stable power for the movement of the first bearing plate 5 and the movable plate 7, ensuring that the bearing plate moves accurately under the action of the drive mechanism to below the embossing mold 3 or offset from the embossing mold 3, thereby improving the working accuracy of the equipment.

[0029] Preferably, the screws 14 in the two linear drive components have opposite thread directions, and the two screws 14 are connected by a synchronous pulley set 19. One of the screws 14 is driven by a servo motor 18 installed in the housing 4. The screws 14 with opposite thread directions, in conjunction with the synchronous pulley set 19, enable the first bearing plate 5 and the movable plate 7 to move synchronously in opposite directions under the drive of the servo motor 18. This ensures that the first bearing plate 5 and the second bearing plate 6 can move alternately according to the design requirements, eliminating the need for a complex control system, simplifying the equipment structure, and improving drive efficiency.

[0030] Example 2

[0031] This embodiment is an improvement on embodiment 1, specifically as follows:

[0032] Please see Figure 1 and Figure 2 The outer wall of the box 4 is also symmetrically fixed with L-shaped support plates 20. A cooling box 21 is fixedly installed on the top surface of the support plate 20. A fan 22 is installed inside the cooling box 21, and a guide frame 23 is installed on the side of the cooling box 21 near the box 4. The arrangement of the cooling box 21, the fan 22 and the guide frame 23 can guide the cooling airflow through the guide frame 23 to the embossed leather after the leather embossing is completed, thereby accelerating the cooling and shaping process of the leather. This changes the existing equipment's passive waiting for natural cooling, greatly shortens the cooling time and improves the leather embossing efficiency.

[0033] In addition, a controller 24 is fixedly installed on the housing 4. The controller 24 is electrically connected to the servo motor 18 and the fan 22. It is used to control the forward and reverse rotation of the servo motor 18 and the start and stop of the fan 22. The controller 24 realizes the automated control of the equipment drive mechanism and cooling mechanism. The operator can conveniently control the alternating movement of the first support plate 5 and the second support plate 6 and the operation of the cooling fan 22 through the controller 24, which improves the automation level and operation convenience of the equipment and makes the whole embossing process more efficient and orderly.

[0034] Working principle:

[0035] During operation, the controller 24 controls the servo motor 18 to drive the linear drive assembly. Since the two lead screws 14 have opposite screw directions and are driven by the synchronous pulley group 19, the first support plate 5 and the movable plate 7 move synchronously in opposite directions. Before the first support plate 5 meets the second support plate 6, the drive rod 10 slides in the "U"-shaped slot 12 of the fixed plate 11, and drives the second support plate 6 downward through the round rod 8, so that the second support plate 6 is offset from the first support plate 5. The first support plate 5 moves to the bottom of the embossing mold 3 first. The embossing mold 3 embosses the leather on the heating groove of the first support plate 5. After the embossing is completed, the servo motor 18 reverses, and the first support plate 5 leaves the embossing mold 3. At the same time, the movable plate 7 drives the second support plate 6 to move to the bottom of the embossing mold 3 for embossing. At this time, the operator can place new leather on the first support plate 5 that is offset from the embossing mold 3.

[0036] During or after embossing, the controller 24 starts the fan 22, and the cooling airflow passes through the guide frame 23 to cool the embossed leather. Through the alternating movement of the first support plate 5 and the second support plate 6, a dual-station embossing operation is achieved, preventing hands from entering the danger zone, while accelerating cooling and improving the safety and efficiency of embossing.

[0037] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
