The outer walls of the driving wheel 205 and the driven wheel 207 are connected by a belt 206. A mounting block 208 is fixedly connected to the belt 206. An electric telescopic rod 209 is installed at the bottom of the mounting block 208. A variable current motor 211 is installed at the bottom of the electric telescopic rod 209. A grinding disc 210 is connected to the driving end of the variable current motor 211.

[0032] In the utility model, the servo motor 201 drives the screw rod 202 to rotate, so that the installation frame 203 slides on the outer wall of the screw rod 202, and the screw rod 202 drives the grinding disc 210 to move horizontally through the installation frame 203, and the grinding disc 210 can grind the leather in the horizontal direction, start the DC motor 204, and the DC motor 204 drives the active rotating wheel 205 to rotate. The active rotating wheel 205 is connected to the driven rotating wheel 207 through the belt 206. The mounting block 208 moves longitudinally when the belt 206 is driven, and the grinding disc 210 can grind the leather in the longitudinal direction, and the servo motor 201 is started and The DC motor 204 adjusts the support plate 10 to a suitable position above the leather in the horizontal and vertical directions. The telescopic end of the electric telescopic rod 209 stretches downward, and after the grinding disc 210 is pressed against the leather surface, the grinding disc 210 is driven to grind the part of the leather.

By grinding the specific area of ​​the leather, local grinding, trimming and aging treatment are performed as needed, so as to highlight its texture and texture, thereby achieving an antique effect, which can make the leather surface present a sense of history and age, and enhance the texture and aesthetics of the leather.

[0033] Furthermore, as a specific implementation of the utility model, the utility model provides a polishing mechanism for antique processing of leather surface.

[0034] Specifically, Figure 1 It is given that a limit rod 4 is installed on the support frame 1, and the mounting frame 203 is slidably connected to the outer wall of the limit rod 4. Two first guide rods 5 are installed on the support frame 1, and the outer wall of the first guide rod 5 is slidably connected to another mounting frame 203, and the driven rotating wheel 207 is rotatably connected to the inside of the other mounting frame 203.

[0035] In the utility model, the limit rod 4 has a limiting effect on the installation frame 203 to prevent the installation frame 203 from rotating along with the rotation of the screw rod 202 when the screw rod 202 is rotating, causing the installation frame 203 to shake and making it impossible for the installation frame 203 to move laterally efficiently and quickly. At the same time, the first guide rod 5 has a guiding effect on the other installation frame 203. The two first guide rods 5 can enable the other installation frame 203 to perform precise lateral movement and move more stably.

[0036] Furthermore, as another specific implementation of the utility model, the utility model provides a polishing mechanism for antique processing of leather surface.

[0037] Specifically, Figure 1 It is shown that two second guide rods 6 are installed between the two installation frames 203 , the installation block 208 is slidably connected to the outer wall of the second guide rod 6 , and the bottom of the servo motor 201 and the DC motor 204 are both installed with a load-bearing plate.

[0038] In the utility model, the second guide rod 6 plays a supporting and guiding role for the mounting block 208, preventing the weight of the mounting block 208 from pulling the belt 206. Pulling the belt 206 will accelerate its wear, thereby shortening the service life of the belt 206. Frequent replacement of the belt 206 not only increases the maintenance cost, but also affects the operating efficiency of the equipment. The second guide rod 6 can make the mounting block 208 move smoothly in the horizontal and longitudinal directions. The mounting frame 203 is connected to another mounting frame 203 through the second guide rod 6. When the servo motor 201 drives the mounting frame 203 to move through the screw rod 202, the mounting frame 203 can drive another mounting frame 203 to slide synchronously through the second guide rod 6. The load-bearing plate mainly supports and fixes the servo motor 201 and the DC motor 204. It can transfer the weight of the servo motor 201 and the DC motor 204 and the vibration generated during operation to the frame or foundation, ensuring the stable operation of the servo motor 201 and the DC motor 204.

[0039] Furthermore, as another specific implementation of the utility model, the utility model provides a polishing mechanism for antique processing of leather surface.

[0044] In the utility model, when the staff puts one side of the leather on the transmission belt 9, the driving motor 7 is started, and the driving motor 7 drives the active roller 8 to rotate. The mutual cooperation between the active roller 8 and the driven roller 11 can drive the transmission belt 9 to transmit, and the leather is moved to the middle. The leather is then fixed by the fixing component 3 to prevent the leather from shifting when the polishing component 2 polishes the leather, thereby affecting the polishing effect. After the polishing is completed, the driving motor 7 is started again, and the transmission belt 9 transports the polished leather. There is no need to manually remove the leather, which saves time and effort.

[0045] Furthermore, as another specific implementation of the utility model, the utility model provides a polishing mechanism for antique processing of leather surface.
