TECHNICAL FIELD
[0001] The utility model belongs to leather processing technical field, concretely relates to a grinding device for microfiber leather production. BACKGROUND
[0002] Sand grinding is a technique for treating the surface of leather, involving three main steps: surface sanding, internal sanding, and napping sanding. Surface sanding refers to using sandpaper to polish the surface of leather, the main purpose being to remove small defects on the surface, thereby improving the appearance quality of the leather. Internal sanding is to polish the inner layer of leather, the purpose being to make the thickness of the leather consistent, clean the inner layer, and prepare for subsequent surface sanding and napping sanding. Napping sanding is a special treatment for the surface of leather, resulting in a soft napping effect.
[0003] The existing grinding device cannot adapt to different thicknesses of leather and cannot control the polishing degree of leather, resulting in low quality of the produced and processed leather.
[0004] The Chinese utility model patent with the authorized announcement number CN218174993U discloses a grinding device for leather production, which comprises a rack, a motor one and a motor two. The motor one is installed outside the rack. The motor two is installed outside the rack on one side of the motor one. A grinding sand roller group is fixedly sleeved on the output shaft of the motor one. A transmission belt is transmissionally sleeved on one end of the grinding sand roller group outside the rack. A transmission roller group is transmissionally sleeved in the inner circle of the transmission belt. The grinding device for leather production improves the dust removal efficiency of the device by installing a bellows inside the rack. When the motor one operates, the belt drives the linkage shaft to rotate, the linkage shaft drives the fan blade group to rotate synchronously, the rotation of the fan blade group generates negative pressure to remove dust from the top of the leather. When the dust and impurities are removed and enter the inside of the bellows, they are intercepted by the filter screen and enter the inside of the dust collection box. After processing is completed, the dust collection box can be pulled out for cleaning, thereby improving the dust removal efficiency of the device.

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.
[0020] Example 1:
[0021] like Figures 1-4 As shown, the present invention provides a leather grinding device for microfiber leather production, comprising a frame 1, on which a feed roller shaft 2 and a take-up roller shaft 3 are fixedly mounted. A support plate 4 is fixedly mounted on the frame 1 between the feed roller shaft 2 and the take-up roller shaft 3. A sub-frame 5 is fixedly mounted on the frame 1. A crossbeam 7 is movably mounted on the sub-frame 5 via an adjustment mechanism 6. A drive motor 8 is fixedly mounted on the top of the crossbeam 7. Slide rails 9 are fixedly mounted on both sides of the crossbeam 7. A movable table 11 is slidably connected to the slide rails 9 via a slider 10. A file 12, a brush 13, and a dust suction nozzle 14 are fixedly mounted on the movable table 11. The file 12 is located near the feed roller shaft 2, the dust suction nozzle 14 is located near the take-up roller shaft 3, and the brush 13 is located between the file 12 and the dust suction nozzle 14. A first adjustable baffle 15 and a second adjustable baffle 16 are fixedly mounted on both sides of the support plate 4 on the frame 1. The adjustment mechanism 6 is provided with an adjustment handwheel 17. The distance between the first adjustable baffle 15 and the second adjustable baffle 16 is greater than the width of the movable platform 11. The brush 13 includes a frame 18 and bristles 19. The frame 18 is provided with bolt posts 20 and pins 21. The movable platform 11 is provided with a first insertion hole 22 and a second insertion hole 23. The bolt posts 20 are inserted into the first insertion hole 22, and the pins 21 are inserted into the second insertion hole 23. The bristles 19 are made of nylon.
[0022] Through the above technical solution, the frame 1 of this utility model is fixedly installed with a sub-frame 5. The sub-frame 5 is movably installed with a crossbeam 7 through an adjustment mechanism 6. A drive motor 8 is fixedly installed on the top of the crossbeam 7. Slide rails 9 are fixedly installed on both sides of the crossbeam 7. The slide rails 9 are slidably connected to a movable table 11 through a slider 10. A file 12, a brush 13, and a dust suction nozzle 14 are fixedly installed on the movable table 11. When grinding leather, the worker adjusts the height of the crossbeam 7 through the adjustment mechanism 6 so that the height of the file 12 on the movable table 11 and the support plate 4 are suitable for the thickness of the leather to be produced. The drive motor 8 is started to move the movable table 11 back and forth, so that the file 12 grinds the leather. By controlling the speed of the drive motor 8, the degree of leather grinding can be controlled, thereby improving the quality of leather production and processing.
[0023] This invention features a polished brush 13 and a vacuum nozzle 14 mounted on the side of the file 12. The brush 13 cleans the dust off the polished leather, and the vacuum device removes the dust, further improving the quality of leather production and processing.
[0024] Example 2:
[0025] like Figures 1-4 As shown, in a microfiber leather production environment, a leather polishing device is installed in the middle of the production line to perform surface polishing between the initial treatment and subsequent processing of the leather. The frame 1 of this invention serves as the supporting structure for the entire device and is securely fixed to the ground. Feed roller 2 and take-up roller 3 are respectively installed at both ends of the frame 1 for conveying leather material. The leather enters from the feed roller 2, is smoothly conveyed by the support plate 4, and finally reaches the take-up roller 3 for collection. On the support plate 4, the leather remains flat for subsequent polishing. A sub-frame 5 is installed on the frame 1 and connected to the crossbeam 7 via an adjustment mechanism 6. The adjustment handwheel 17 is located on the side of the adjustment mechanism 6, allowing the operator to easily rotate the handwheel to adjust the height of the crossbeam 7, adapting the distance between the file 12 and the support plate 4 to accommodate leather of different thicknesses. A drive motor 8 is fixedly installed on the crossbeam 7, providing power to the movable table 11. Slide rails 9 are installed on both sides of the crossbeam 7, which cooperate with the slider 10 to ensure smooth sliding of the movable table 11. The worktable 11 is equipped with a file 12, a brush 13, and a suction nozzle 14. The file 12 is located near the feed roller shaft 2 and is used for initial sanding of the leather surface. The brush 13 is located between the file 12 and the suction nozzle 14 and is used to clean up the dust generated during sanding. The suction nozzle 14 is located near the take-up roller shaft 3 and is responsible for sucking away the dust generated during sanding to keep the working environment clean. The frame 1 is also equipped with a first adjustable baffle 15 and a second adjustable baffle 16, located on both sides of the support plate 4, to limit the lateral movement of the leather and ensure the stability of the sanding process.
[0026] Example 3:
[0027] As Figures 1-4 shown, the adjusting hand wheel 17 of the utility model is one of the key adjusting mechanisms 6 during operation. The operator can control the height of the beam 7 by rotating the adjusting hand wheel 17, thereby adjusting the distance between the file 12 and the leather surface. This adjustment process is very important because different thicknesses of leather require different polishing forces to ensure the uniformity of the surface treatment. The design of the adjusting hand wheel 17 allows the operator to easily make fine adjustments, ensuring that the file 12 can contact the leather surface at the optimal angle. When making adjustments, the operator can determine whether further adjustment of the adjusting hand wheel 17 is needed by observing the polishing effect. In this way, the device can adapt to different types and thicknesses of leather materials, thereby providing greater flexibility and higher processing quality in the production process.
[0028] Example Four:
[0029] As Figures 1-4 shown, the first adjustable baffle 15 and the second adjustable baffle 16 of the utility model are designed to ensure that the leather maintains a stable lateral position during polishing. These two baffles are fixed on the rack 1 and located on both sides of the support plate 4. The operator can adjust the position of the baffles as needed to adapt to different widths of leather materials. The distance between the baffles is designed to be slightly larger than the width of the movable table 11, which ensures that the movable table 11 is not hindered during reciprocating motion, while effectively limiting the lateral movement of the leather. This design can prevent the leather from shifting during polishing, thereby ensuring the uniformity and accuracy of polishing. By adjusting the position of the baffles, the device can flexibly adapt to different sizes of leather, improving production efficiency and product quality.
[0030] Example Five:
[0031] As Figures 1-4 shown, the brush 13 on the movable table 11 of the utility model adopts a modular structure for easy installation and replacement. The brush 13 is composed of a skeleton 18 and bristles 19, and the skeleton 18 is provided with a bolt column 20 and a plug 21. The movable table 11 is pre-drilled with a first insertion hole 22 and a second insertion hole 23 for fixing the bolt column 20 and the plug 21 respectively. When installing the brush 13, the operator only needs to insert the bolt column 20 into the first insertion hole 22 and the plug 21 into the second insertion hole 23 to complete the installation. This design makes the installation and removal of the brush 13 very simple, facilitating regular maintenance and replacement of the bristles 19. The brush 13 is located between the file 12 and the dust suction nozzle 14, responsible for cleaning the dust generated during polishing, ensuring that the leather surface remains clean before entering the dust suction stage. Through this modular design, the device is more convenient to maintain on a daily basis, effectively extending its service life. In the design of the brush 13 of the leather grinding device, the bristles 19 are made of nylon material. This material has excellent wear resistance and flexibility, making it very suitable for cleaning the surface of the leather.
