Description

Technical Field

[0001] This utility model relates to the technical field of leather processing equipment, and in particular to a leather polishing dust collection device. Background Technology

[0002] In the leather processing industry, leather polishing and cutting are core pre-processes for downstream industries such as footwear, bags, and furniture decoration. Their processing quality and production environment control directly impact product quality and worker health. With the advancement of large-scale production and stricter environmental standards, dust generated during processing not only reduces leather surface precision and affects finished product yield, but may also damage the respiratory system of workers. Therefore, efficient dust collection and treatment equipment has become a key supporting facility for leather processing production lines, and its performance optimization is of significant practical importance for improving production efficiency and ensuring operational safety.

[0003] Currently, while mainstream leather polishing dust collection equipment in the industry can achieve basic dust adsorption, there are still two technical issues that need improvement in long-term use. Firstly, the existing dust cleaning mechanisms have limitations: cleaning the filter plates of most equipment requires stopping the machine and disassembling the outer casing or internal components, a time-consuming process that can easily lead to production interruptions. Furthermore, during cleaning, dust on the filter plate surface is easily diffused again by airflow or during operation, and some dust may even be re-adsorbed back onto the filter plate surface. This increases the labor intensity of manual cleaning and makes it difficult to guarantee the long-term filtration efficiency of the filter plates, leading to a decline in dust collection capacity after long-term use. On the other hand, the existing equipment lacks coordination between the adjustment of the cutting components and dust control: the height and angle adjustment of the cutting components often require special tools and multiple steps, making it difficult to quickly adapt to leathers of different thicknesses and cutting requirements; and if the angle of the components is not locked after adjustment, the cutting direction may be deviated due to the resistance of the leather during processing, which not only reduces the cutting accuracy, but also generates additional dust due to excessive friction or cutting misalignment. At the same time, the deviated cutting path may also cause the dust to fall outside the preset absorption range, further reducing the dust collection efficiency.

[0004] In response to this technical problem, this application proposes a leather polishing dust collection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leather polishing dust collection device. External operation triggers a scraper to remove dust and a pull-out storage box for cleaning, preventing secondary dust diffusion and saving time and effort. During cutting, the position and angle of components can be easily adjusted without complicated operations, and it can also prevent cutting direction deviation, improving processing efficiency and accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A leather polishing dust collection device includes a polishing roller and a body. A first support frame is fixedly connected to the left outer wall of the body. The outer wall of the polishing roller is rotatably connected to the inner wall of the first support frame. A second support frame is fixedly connected to the right outer wall of the body. A sliding rod is slidably connected to the upper side of the second support frame. A cutting component is provided below the sliding rod. A conveyor belt is provided in the middle of the upper end of the body. An absorption port is fixedly connected to the upper side of the body. The outer wall of the absorption port is provided on both sides of the conveyor belt. A guide plate is fixedly connected to the inner side of the upper side of the body. A filter plate is fixedly connected to the inner side of the lower side of the guide plate. A cleaning component is provided on the outer wall of the filter plate. A storage box is slidably connected to the inner side of the lower side of the body. A handle is fixedly connected to the left outer wall of the storage box.

[0007] Furthermore, the cleaning component includes a fixed cylinder fixedly connected to the interior of the lower side of the body, a toothed plate II rotatably connected to the interior of the left side of the fixed cylinder, a scraper fixedly connected to the left end of the toothed plate II, and the outer wall of the scraper rotatably connected to the outer wall of the left side of the filter plate.

[0008] Furthermore, the cutting assembly includes a fixed rod fixedly connected to the lower side of the sliding rod, a limit rod rotatably connected to the lower end of the fixed rod, a cutter head rotatably connected to the lower end of the limit rod, a screw threadedly connected to the upper side of the sliding rod, and a knob fixedly connected to the upper end of the screw.

[0009] Furthermore, a second bevel gear is rotatably connected inside the fixed cylinder, and a transmission rod is slidably connected inside the second bevel gear. A toothed plate is fixedly connected to the left end of the transmission rod, and a lever is rotatably connected to the outer wall of the left side of the transmission rod. The other end of the lever is located on the outside of the machine body.

[0010] Furthermore, a first spring is sleeved on the outer wall of the left side of the transmission rod, the outer wall of the first spring is disposed on the left side of the outer wall of the actuating rod, and a fixing plate is disposed on the left side of the first spring, the outer wall of the fixing plate being fixedly connected to the inner wall of the fixing cylinder.

[0011] Furthermore, the second bevel gear is meshed with the first bevel gear on its right side, and a motor is installed inside the rear side of the machine body. The rotating end of the motor is fixedly connected to the first bevel gear, and the outer wall of the right side of the second bevel gear meshes with the first bevel gear.

[0012] Furthermore, a toothed plate is rotatably connected inside the right end of the fixed cylinder, and a fan is fixedly connected to the right end of the toothed plate.

[0013] Furthermore, a push rod is rotatably connected to the left outer wall of the fixed rod. The lower outer wall of the push rod is located inside the limiting rod, and the upper end of the push rod is located on the upper outer wall of the fixed rod. A second spring is provided inside the upper side of the fixed rod.

[0014] This utility model has the following beneficial effects: 1. In this invention, the device can complete the cleaning operation after dust filtration without disassembling the equipment. The internal cleaning structure is triggered by an external operating component, causing a scraper to remove dust from the filter plate surface. The scraped dust falls directly into the collection component below, and the operator only needs to pull out the collection component to complete the dust cleaning. The entire cleaning process does not require prolonged downtime and effectively prevents secondary diffusion or re-adsorption of dust back onto the filter plate during cleaning. This reduces the labor intensity of manual cleaning while ensuring the filtration efficiency of the filter plate and maintaining the device's long-term stable dust collection capacity.

[0015] 2. In this invention, workers can simultaneously optimize dust collection by adjusting the position and angle of the cutting component: rotating the knob on the sliding rod adjusts the height of the cutting component to suit the processing needs of leathers of different thicknesses, avoiding cutting position deviation due to differences in leather thickness and reducing additional dust generation; when adjusting the cutting angle, pressing the push rod releases the limit lock, and after rotating to the appropriate angle, releasing it will cause the push rod to automatically reset and lock under the action of the second spring, ensuring angle stability during the cutting process and reducing the risk of dust diffusion caused by cutting direction deviation. This convenient adjustment design can quickly respond to diverse processing needs and reduce dust generation at the source. Combined with the absorption ports on both sides of the conveyor belt, it further improves dust collection efficiency and ensures a clean processing environment. Attached Figure Description

[0018] 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, dust falls into the collection box, and external operation triggers the scraper to remove dust and pull out the collection box for cleaning, ensuring the efficiency of the filter plate; the cutting component is easy to adjust, can adapt to different processing needs, maintains cutting stability, and reduces the generation of unnecessary dust.

[0019] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides a leather polishing dust collection device, including a polishing roller 1 and a body 3. A first support frame 2 is fixedly connected to the outer wall of the left side of the body 3. The outer wall of the polishing roller 1 is rotatably connected to the inner wall of the middle of the first support frame 2. A second support frame 10 is fixedly connected to the outer wall of the right side of the body 3. A sliding rod 11 is slidably connected to the upper side of the second support frame 10. A fixed rod 26 is provided on the lower side of the sliding rod 11. A limit rod 27 is rotatably connected to the lower end of the fixed rod 26. A cutter head 28 is rotatably connected to the lower end of the limit rod 27. A screw is threadedly connected to the upper side of the sliding rod 11. A knob 23 is fixedly connected to the upper end of the screw. A conveyor belt 9 is installed in the middle of the upper part of the machine body 3. An absorption port 4 is fixedly connected to the upper side of the machine body 3. The outer walls of the absorption port 4 are set on both sides of the conveyor belt 9. A guide plate 12 is fixedly connected to the inner side of the upper part of the machine body 3. A filter plate 13 is fixedly connected to the inner side of the lower side of the guide plate 12. A fixed cylinder 14 is set on the outer wall of the filter plate 13. A toothed plate 21 is rotatably connected to the inner left side of the fixed cylinder 14. A scraper 17 is fixedly connected to the left end of the toothed plate 21. The outer wall of the scraper 17 is rotatably connected to the outer left side of the filter plate 13. A storage box 6 is slidably connected to the inner side of the lower part of the machine body 3. A handle 5 is fixedly connected to the outer left side of the storage box 6.

[0020] Specifically, the device is mainly used to absorb sanding dust from leather. The leather is sanded and cut by the sanding roller 1 on the left and the sliding rod 11 on the right. The generated dust is sucked into the machine body 3 through the absorption ports 4 on both sides, and then guided by the inclined surface of the guide plate 12 on the lower side, so that the dust is absorbed from left to right. During this process, the motor 15 drives the first bevel gear 18 to rotate, which in turn drives the second bevel gear 29 to rotate. The rotation of the second bevel gear 29 causes the transmission rod 19 to rotate, which in turn causes the toothed plate 20 to drive the fan 8 to rotate. A negative pressure is formed inside the device to keep the internal gas flow stable. When the dust passes through the filter plate 13, it is blocked on the left surface. When cleaning is required, it can be turned by... The lever 7 is activated, causing one end of the lever 7 to move the transmission rod 19 to the left. The transmission rod 19 slides to the left, causing the toothed plate 21 and the toothed plate 22 to mesh and connect, transmitting kinetic energy and driving the scraper 17 to rotate. This causes the dust on the outside to fall into the storage box 6 on the lower side, where it is pulled out for cleaning. As the transmission rod 19 moves to the left, the toothed plate 20 loses its connection, thus preventing the fan 8 from rotating. This prevents the dust from being sucked back onto the outside by the wind when it falls, thus affecting the cleaning efficiency. The middle part of the lever 7 is rotatably connected to the inside of the body 3. Through the lever principle, one end of the lever slides. When released, the first spring 16 rebounds, causing the device to automatically reset. The outer fixing cylinder 14 prevents dust from interfering with the internal parts. During the cutting process, the position of the sliding rod 11 outside the second support frame 10 can be controlled by rotating the knob 23. When it is necessary to change the direction of the blade head 28, the edge of the pressing rod 24 can be pressed so that the lower side of the pressing rod 24 can be raised. Rotate the handle part with your finger. When the appropriate angle is adjusted, release it. The front end of the pressing rod 24 will stay in the groove on the outer wall of the limiting rod 27. The second spring 25 inside the upper side of the pressing rod 24 will always press against the upper side of the pressing rod 24, so that the lower side can always be in contact. When the lower side of the pressing rod 24 is in contact, the limiting rod 27 cannot rotate, so the handle and the blade head 28 cannot rotate, which can prevent the resistance of the leather from changing the cutting direction of the blade head 28.

[0021] Reference Figure 2 , Figure 3 and Figure 5A second bevel gear 29 is rotatably connected inside the fixed cylinder 14. A transmission rod 19 is slidably connected inside the second bevel gear 29. A toothed plate 22 is fixedly connected to the left end of the transmission rod 19. A toggle rod 7 is rotatably connected to the left outer wall of the transmission rod 19, and the other end of the toggle rod 7 is located on the outside of the machine body 3. A first spring 16 is sleeved on the left outer wall of the transmission rod 19. The outer wall of the first spring 16 is located on the left side of the outer wall of the toggle rod 7. A fixing plate is located on the left side of the first spring 16, and the outer wall of the fixing plate is fixedly connected to the inner wall of the fixed cylinder 14. A motor 15 is located inside the rear side of the machine body 3. A first bevel gear 18 is fixedly connected to the rotating end of the motor 15. The right outer wall of the second bevel gear 29 meshes with the first bevel gear 18. A toothed plate 20 is rotatably connected inside the right end of the fixed cylinder 14, and a fan 8 is fixedly connected to the right end of the toothed plate 20. A push rod 24 is rotatably connected to the left outer wall of the fixed rod 26. The lower outer wall of the push rod 24 is set inside the limiting rod 27, and the upper end of the push rod 24 is set on the upper outer wall of the fixed rod 26. A second spring 25 is set inside the upper side of the fixed rod 26.

[0022] Specifically, inside the fixed cylinder 14, a second bevel gear 29 is rotatably connected. This is a key intermediate component for power transmission, receiving power from other gears and transmitting it to the transmission rod 19. The transmission rod 19, slidably connected inside the second bevel gear 29, undertakes the dual tasks of power transmission and mode switching. Its left end is fixedly connected to a toothed plate 22, which can mesh with other toothed plates under specific operating conditions to achieve power steering and transmission. A lever 7 is rotatably connected to the left outer wall of the transmission rod 19, with its other end located on the outside of the machine body 3. Operators can easily control the movement of the transmission rod 19 by operating the lever 7 on the outside of the machine body 3, thereby changing the working state of the device. A first spring 16 is fitted onto the outer left wall of the transmission rod 19. The outer wall of the first spring 16 is located on the left side of the outer wall of the actuating rod 7, and a fixing plate is provided on the left side of the first spring 16. The outer wall of the fixing plate is fixedly connected to the inner wall of the fixing cylinder 14. The first spring 16 mainly serves a reset function. When the operator releases the actuating rod 7, the first spring 16 can push the transmission rod 19 back to its initial position. At the same time, the fixing plate provides stable support for the first spring 16, ensuring that its elastic function is properly performed. The outer right wall of the second bevel gear 29 is meshed with the first bevel gear 18. The motor 15 is located inside the rear side of the machine body 3, and its rotating end is fixedly connected to the rear side of the first bevel gear 18. The motor 15 serves as the power source of the device. When working, it drives the first bevel gear 18 to rotate, and then drives the second bevel gear 29 to rotate through gear meshing, providing power for the entire transmission system. A toothed plate 20 is rotatably connected to the right end of the fixed cylinder 14, and a fan 8 is fixedly connected to its right end. When the transmission system drives the toothed plate 20 to rotate, the toothed plate 20 drives the fan 8 to rotate. The rotation of the fan 8 generates negative pressure, which allows the device to smoothly suck in the dust generated by grinding through the absorption port 4. In the cutting-related structure, a push rod 24 is rotatably connected to the left outer wall of the fixed rod 26. Its lower outer wall is set inside the limiting rod 27, and its upper end is set on the upper outer wall of the fixed rod 26. A second spring 25 is provided inside the upper side of the fixed rod 26. The push rod 24 is mainly used to control the rotation of the limiting rod 27, thereby realizing the adjustment and fixation of the angle of the cutter head 28. The second spring 25 provides elasticity to the push rod 24, ensuring that the push rod 24 can fit tightly against the limiting rod 27 in the non-operating state, limiting the rotation of the limiting rod 27, thereby ensuring the stability of the angle of the cutter head 28 during the cutting process and avoiding the change of the cutting direction of the cutter head 28 due to the resistance of the leather.

[0023] Working principle: When the filter plate 13 needs cleaning, the operator moves the lever 7 on the outside of the motor body 3, causing the transmission rod 19 to move to the left and compress the first spring 16. At this time, the transmission rod 19 disengages from the toothed plate 20, and the fan 8 stops to prevent secondary dust adsorption; simultaneously, the toothed plate 22 on the left end of the transmission rod 19 engages with the toothed plate 21, causing the scraper 17 to rotate on the left side of the filter plate 13, scraping the dust down to the collection box 6 below. After releasing the lever 7, the first spring 16 pushes the transmission rod 19 back to its original position, and the device returns to the collection state. The operator can then pull out the collection box 6 through the handle 5 to clean the dust. During the cutting process, the knob 23 on the rotating sliding rod 11 can be used to adjust the position of the sliding rod 11 to change the height of the cutter head 28. When the angle of the cutter head 28 needs to be adjusted, the edge of the pressing rod 24 is pressed, so that its upper end compresses the second spring 25 and its lower end disengages from the limiting rod 27. After adjusting the angle by rotating the limiting rod 27, it is released. The second spring 25 pushes the lower end of the pressing rod 24 into the groove of the limiting rod 27, restricting its rotation and ensuring the stability of the cutter head 28.
