Description
Technical Field
[0001] This utility model relates to the field of leather processing technology, specifically a high-precision leather grinding device. Background Technology
[0002] Suede leather is made from buffalo or cowhide that has been sanded using a tanning machine to create a velvety surface. Shoes made from this leather are more breathable, comfortable, and have a high-quality look. Suede is made by polishing the surface of leather and abrading away any grain scars or rough fibers to expose the even and smooth leather fiber structure. It is then dyed in various trendy colors to create a matte finish, similar to frosted glass.
[0003] Leather polishing is done using a polishing machine. Two workers each hold one corner of the leather and feed it into the machine. The polishing shaft rotates to polish the leather. However, during polishing, workers need to put their hands very close to the polishing shaft, which can easily cause injury. At the same time, a lot of dust and the scraped material on the leather surface are scattered during polishing, and workers must wear masks, which affects their health. Therefore, we propose a high-precision leather polishing device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figure 1-3 This embodiment provides a technical solution: a high-precision leather polishing device, including a frame 1 and a pre-dust removal mechanism 2;
[0023] Frame 1: A skin-grinding mechanism 5 is installed at its rear end. Fixed seats distributed front and back are fixedly connected to both the left and right sides of the upper surface of frame 1. The skin-grinding mechanism 5 includes a polishing roller 54, a second protective cover 55, and a third motor 56. The polishing roller 54 is rotatably connected between the two rear fixed seats, and the second protective cover 55 is fixedly connected between the two rear fixed seats. The polishing roller 54 is located inside the second protective cover 55. The third motor 56 is fixedly connected to the right side of the fixed seat at the right rear end. The output shaft of the third motor 56 is fixedly connected to the right end of the polishing roller 54. The input end of the third motor 56 is electrically connected to the output end of the control switch 6. The skin-grinding mechanism 5 also includes a second motor 51, a second rotating shaft 52, and synchronous pulleys 53. The rear ends of the left and right side walls of frame 1 are rotatably connected to the second rotating shaft 52, which is distributed front and back. Evenly distributed synchronous pulleys 53 are fixedly fitted onto the outside of each second rotating shaft 52. The two adjacent synchronous pulleys 53 are connected at the front and back. All components are connected via synchronous belt drive. Motor 2 51 is fixedly connected to the left side of the frame 1. The output shaft of motor 2 51 is fixedly connected to the rear rotating shaft 2 52. The input end of motor 2 51 is electrically connected to the output end of control switch 6. The output shaft of motor 3 56 drives polishing roller 54 to rotate. The output shaft of motor 2 51 drives the rear rotating shaft 2 52 to rotate. The rear synchronous belt pulley 53 rotates, driving all synchronous belts to rotate. The speed of polishing roller 54 is much higher than that of synchronous belt, rear rotating pulley 25 and front rotating pulley 26, so that the leather is pulled forward by polishing roller 54 while being polished, so that the leather is completely flattened while being polished. The synchronous belt also drives the polished leather part forward. The surface of the polished leather is smoother and achieves high-precision polishing. Dust removal duct 7 is connected to fan. Negative pressure is formed inside protective cover 2 55 and protective cover 1 22. Dust blown down by ion wind and dust generated by polishing are sucked away.
[0024] Pre-dust removal mechanism 2: It includes a gear 21, a rotating shaft 24, a rear rotating wheel 25, a front rotating wheel 26, a mounting frame 27, and ion air knives 28. The mounting frame 27 is fixedly connected between two fixed seats on the front side. Ion air knives 28 are evenly distributed and fixedly connected to the front side of the mounting frame 27. Rotating shafts 24, symmetrically distributed vertically, are rotatably connected between the front and rear ends of the two fixed seats on the front side. Evenly distributed front rotating wheels 26 are fixedly sleeved on the outside of the front rotating shaft 24, and evenly distributed rear rotating wheels 25 are fixedly sleeved on the outside of the rear rotating shaft 24. The front and rear rotating wheels 26 are staggered. Gears 21 are fixedly fitted on the left side of shaft 24. Two vertically adjacent gears 21 are meshed together. Ion air knives 28 are located at the upper middle part of the shaft 24 on both the front and rear sides. The air inlets of the ion air knives 28 are connected to the air outlets of external air pumps. The pre-dust removal mechanism 2 also includes a protective cover 22 and protective baffles 23. The protective cover 22 is fixedly connected between the two fixed seats on the front side. Evenly distributed protective baffles 23 are provided on the front side of the protective cover 22, located between two adjacent front rotating wheels 26. A motor cover is fixedly connected to the right side of the frame 1. The upper shaft 24... On the right side, sprockets 3 are fixedly mounted, and the sprockets 3 are located inside the motor cover. The two sprockets 3 are connected by a chain drive. A motor 4 is fixedly connected to the right side of the motor cover. The output shaft of motor 4 is fixedly connected to the upper front shaft 24. The input end of motor 4 is electrically connected to the output end of control switch 6. The upper ends of protective cover 55 and protective cover 22 are connected by a dust removal duct 7. Two workers drag the leather to the front end of the frame 1 by dragging the two corners of the leather. The output shaft of motor 4 drives the sprockets 3 and shaft 24 on the front side to rotate, and drives the shaft 24 on the rear side to rotate via the chain. The vertically adjacent rotating shafts 24 rotate relative to each other through the transmission of gear 21. Both the rear rotating wheel 25 and the front rotating wheel 26 rotate. The worker pulls the leather by the two corners and pulls it through the protective baffle 23 into the interior of the protective cover 22. There is a certain distance between each rear rotating wheel 25 and each front rotating wheel 26. The protective baffle 23 keeps the worker's hands away from the front rotating wheel 26 and prevents the worker's hands from touching the front rotating wheel 26, thus protecting the worker. The ion air knife 28 makes the compressed air pumped by the air pump carry ions, eliminates the static electricity on the surface of the leather, and makes it difficult for dust to adhere to the surface of the leather. The dust is blown off the leather by the ion air.
[0025] It also includes a control switch 6, which is located on the left side of the frame 1. The input end of the control switch 6 is electrically connected to an external power supply, and the input ends of the ion air knife 28 are electrically connected to the output end of the control switch 6.
[0026] The working principle of the high-precision leather polishing device provided by this utility model is as follows: Two workers drag the leather by its two corners to the front end of the frame 1. The output shaft of motor 4 drives the front sprocket 3 and rotating shaft 24 to rotate, which in turn drives the rear rotating shaft 24 to rotate via a chain. The vertically adjacent rotating shafts 24 rotate relative to each other through the transmission of gear 21. Both the rear rotating wheel 25 and the front rotating wheel 26 rotate. The workers pull the leather by its two corners through the protective baffle 23 into the protective cover 22. There is a certain distance between each rear rotating wheel 25 and each front rotating wheel 26. The protective baffle 23 keeps the workers' hands away from the front rotating wheel 26, preventing them from touching it and protecting the workers. The ion air knife 28 carries ions in the compressed air pumped by the air pump, eliminating static electricity on the leather surface and making it difficult for dust to accumulate. Dust adhering to the surface of the leather is blown off by the ion wind. The leather is then pulled to the polishing roller 54 by the vertically adjacent rear roller 25 and front roller 26. The output shaft of motor 3 56 drives the polishing roller 54 to rotate, and the output shaft of motor 2 51 drives the rear shaft 2 52 to rotate. The rear synchronous belt pulley 53 rotates, driving all synchronous belts to rotate. The rotation speed of the polishing roller 54 is much higher than that of the synchronous belt, rear roller 25, and front roller 26, so that the leather is pulled forward by the polishing roller 54 while being polished, making the leather completely flat during polishing. The synchronous belts then drive the polished leather part forward, resulting in a smoother and more even leather surface after polishing, achieving high-precision polishing. The dust removal duct 7 is connected to the fan, and negative pressure is formed inside both the protective cover 2 55 and the protective cover 1 22, so that the dust blown off by the ion wind and the dust generated during polishing are sucked away.
[0027] It is worth noting that the ion air knife 28 disclosed in the above embodiments can be an AMS-016S ion air knife, the motor 4 can be an RV series geared motor, the motor 51 can be a YE5VF series speed regulating motor, and the motor 56 can be a YE3-100L1-4 three-phase asynchronous motor. The control switch 6 is equipped with switch buttons corresponding to the ion air knife 28, the motor 4, the motor 51, and the motor 56 to control their switching operation.
