[0027] The present utility model provides a leather grinding machine as Figures 1-4 shown, which includes a main chassis 2 and a power chassis 5 arranged at the top left end of the main chassis 2. The main chassis 2 and the power chassis 5 are fixedly connected by welding. A roller output shaft 8 is inserted into the upper side at the center of the outer wall of the right end of the power chassis 5. A grinding leather roller 6 is fixedly sleeved outside the roller output shaft 8. Support feet 1 are arranged at the four corners of the bottom of the main chassis 2. Anti-slip pads are arranged at the bottoms of the multiple support feet 1. A maintenance door 3 is arranged inside the front end of the main chassis 2. Heat dissipation holes are densely arranged inside the maintenance door 3. When using this leather grinding machine, first, the leather grinding machine needs to be placed on the workshop floor through the support feet 1 at the bottom of the main chassis 2. Then, the electrical components inside the main chassis 2 and the power chassis 5 need to be connected to the power supply. Then, the grinding leather roller 6 needs to be sleeved onto the outside of the roller output shaft 8 from right to left, and then the grinding leather roller 6 is fixed with a special nut, so that the grinding conveyor shaft can drive the grinding leather roller 6 to rotate at a high speed. Then, it is ready to carry out grinding processing on the leather.

[0028] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, multiple lifting cylinders are arranged inside the main chassis 2. Inside each of the multiple lifting cylinders, a cylinder lifting shaft 9 is connected through a plunger. The tops of the multiple cylinder lifting shafts 9 are connected to a lifting adjustment platform 15. The lifting adjustment platform 15 is located above the outer wall at the top of the main chassis 2. The lifting cylinders can drive the lifting adjustment platform 15 to move up and down through the cylinder lifting shafts 9. On the upper part of the top outer wall of the lifting adjustment platform 15, push-pull tracks 14 are arranged on both the left and right sides of the center. Inside each of the two push-pull tracks 14, a T-shaped push-pull sliding groove 10 is arranged. The T-shaped opening direction of the T-shaped push-pull sliding groove 10 is upward. When processing leather by grinding, a special fixture needs to be fixed to the leather grinding fixing table, and then the leather to be processed by grinding is laid flat on the leather grinding fixing table, and the laid flat leather is fixed with a special fixture. Then, it is necessary to start the multiple lifting cylinders inside the main chassis 2 through the control box 4, so that the lifting cylinders drive the lifting adjustment platform 15 to move up and down through the cylinder lifting shafts 9. In this way, the leather grinding fixing table will drive the fixed leather to move up and down, so that the top outer wall of the leather can fully and closely contact the bottom outer wall of the leather grinding roller 6. Then, the controller inside the front part of the power chassis 5 can be started to start the motor inside it, so that the motor drives the roller output shaft 8 to rotate at a high speed through the coupling. The roller output shaft 8 will drive the leather grinding roller 6 to rotate at a high speed, so that the rotating leather grinding roller 6 at a high speed can grind and process the leather in contact with its bottom end.

[0029] As Figure 1 、 Figure 2 and Figure 3 shown, a leather grinding fixing plate 12 is arranged above the lifting adjustment platform 15. On both the left and right sides of the center at the bottom of the leather grinding fixing plate 12, T-shaped push-pull sliders 11 are welded. The two T-shaped push-pull sliders 11 are respectively inserted into the two T-shaped push-pull sliding grooves 10. The leather grinding fixing plate 12 can move back and forth through the T-shaped push-pull sliders 11 inserted into the T-shaped push-pull sliding grooves 10. A push-pull handle 13 is arranged at the center of the front outer wall of the leather grinding fixing plate 12. A control box 4 is arranged inside the front part of the main chassis 2. When the motor inside the power chassis 5 drives the leather grinding roller 6 to rotate at a high speed, in order to enable the leather grinding roller 6 to comprehensively grind the leather laid flat and fixed on the leather grinding fixing plate 12, at this time, the user needs to hold the push-pull handle 13 with the palm, and then drive the front end of the leather grinding fixing plate 12 to move through the palm. The back-and-forth movement of the leather grinding fixing plate 12 can enable the laid flat and fixed leather to fully contact the leather grinding roller 6, so as to comprehensively grind and process the leather. When the leather grinding fixing plate 12 moves back and forth, it mainly relies on the T-shaped push-pull sliders 11 inserted into the T-shaped push-pull sliding grooves 10 inside the push-pull tracks 14 to move. The T-shaped new push-pull slider can not only move back and forth normally in the T-shaped push-pull sliding groove 10, but also will not derail, ensuring that the leather grinding fixing plate 12 can move back and forth stably, so as to comprehensively grind the leather.

[0030] As Figure 1 andFigure 4 As shown in the figure, an operation protection device 7 is provided on the front side of the leather grinding roller 6. The operation protection device 7 includes fixing screws 16, a metal fixing socket 17, a rectangular protection baffle 18, and a disassembly and assembly handle 19. The metal fixing socket 17 is welded to the outer wall of the right end of the power machine box 5. The opening direction of the metal fixing socket 17 faces outward. The metal fixing socket 17 is located on the front side of the left end of the leather grinding roller 6. A rectangular protection baffle 18 is inserted into the metal fixing socket 17. The rectangular protection baffle 18 and the metal fixing socket 17 are fixedly connected by a plurality of fixing screws 16. A disassembly and assembly handle 19 is provided on the outer wall of the front end of the rectangular protection baffle 18. The length of the rectangular protection baffle 18 is equal to the length of the leather grinding roller 6. The rectangular protection baffle 18 is located directly in front of the leather grinding roller 6. The rectangular protection baffle 18 is made of aluminum alloy. After the left end of the rectangular protection baffle 18 is inserted into the metal fixing socket 17, a plurality of fixing screws 16 are needed to fix the rectangular protection baffle 18. Fixing with a plurality of fixing screws 16 can prevent the rectangular protection baffle 18 from shaking, ensuring that the rectangular protection baffle 18 can stably protect the front side of the leather grinding roller 6. When the user pushes and pulls the leather grinding fixing plate 12 back and forth with the palm to grind the leather, once the palm approaches the leather grinding roller 6, the rectangular protection baffle 18 located on the front side of the leather grinding roller 6 will block the palm to prevent the palm from directly contacting the high-speed rotating leather grinding roller 6, thus avoiding the high-speed rotating leather grinding roller 6 from grinding the user's palm.

[0031] As Figure 1 and Figure 4 shown in the figure, the operation protection device 7 further includes a cleaning roller 20 and roller fixing clamps 21. Roller fixing clamps 21 are provided on both the left and right sides of the center of the outer wall of the rear end of the rectangular protection baffle 18. The two roller fixing clamps 21 are fixedly connected to the rectangular protection baffle 18 by welding. A cleaning roller 20 is provided between the two roller fixing clamps 21. Both ends of the cleaning roller 20 are provided with roller shafts. Shaft holes are provided inside the two roller fixing clamps 21. The two roller shafts are respectively inserted into the two shaft holes. The cleaning roller 20 can rotate clockwise and counterclockwise between the two roller fixing clamps 21. The rear end of the cleaning roller 20 is in contact with the front end of the leather grinding roller 6. After the left end of the rectangular protection baffle 18 is inserted into the metal fixing socket 17 and fixed by the fixing screws 16, the cleaning roller 20 rotatably fixed by the two roller fixing clamps 21 is then in contact with the front end of the leather grinding roller 6 at this time. When the leather grinding roller rotates, because the front end of the leather grinding roller 6 is directly in contact with the rear end of the cleaning roller 20, the cleaning roller 20 will be driven to rotate synchronously, so that the situation where the cleaning roller 20 causes damage to the leather grinding roller 6 will not occur. And because the cleaning roller 20 is directly in contact with the leather grinding roller 6, the residues attached to the outer wall of the leather grinding roller 6 can be cleaned off, avoiding the situation where too many residues are attached to the outer wall of the leather grinding roller 6 and affecting the leather grinding effect of the leather grinding roller 6.

[0032] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
