[0002] A chain is a mechanical transmission component consisting of multiple rigid links connected in series by flexible connectors. It has core functions such as transmitting power, bearing loads, and adapting to complex motion trajectories. As a basic component in mechanical transmission, the chain occupies an irreplaceable position in industries such as industry, transportation, and energy due to its advantages of simple structure, strong adaptability, and high load-bearing capacity. After the chain is cut and shaped, metal burrs or sharp edges are easily generated at the cut, which need to be removed by grinding to avoid damage to equipment or operators during subsequent assembly or use.

[0003] In existing technologies, chain polishing requires manual operation by workers, resulting in low efficiency. The number of chains polished per unit time is limited by factors such as worker skill level, physical exertion, and working hours, making it difficult to meet the ever-increasing market demand. This leads to longer product delivery cycles, impacting the company's market competitiveness. Furthermore, it easily causes worker fatigue and muscle strain, and the dust generated during polishing can trigger various occupational diseases, seriously harming workers' health. Therefore, there is a need to improve the chain processing edge-cutting and polishing device to solve these problems. Utility Model Content

A second gear 212 is fixedly connected to the first grinding roller 29. A first gear 211 meshes with the outer side of the second gear 212. A gear for grinding the chain body is fixedly connected inside the first gear 211. The second grinding roller 210, which grinds the inner side of the chain 25, is rotatably connected to the inside of the grinding frame 27. The grinding frame 27 has a collection box 219 inside to collect grinding dust. The collection box 219 drives a filter plate 220, which is fixedly connected inside to filter dust. A fixing assembly for fixing the collection box 219 is provided on the top of the workbench 1. This assembly moves via an L-shaped bracket 23, straightening the chain body 25. The first grinding roller 29 and the second grinding roller 210 then grind the chain. The chain body 25 is polished by spraying coolant through the cooling nozzle 217, which sprays coolant onto the chain body 25 for cooling. This shortens the polishing time required for the chain body 25, improves the polishing effect, enhances the quality of the chain body 25, increases polishing efficiency, and prevents harm to the health of workers. The fixing component allows for easy fixing and disassembly of the collection box 219, facilitating the collection and disposal of polishing dust and coolant.

[0024] Please see Figure 1 - Figure 5In this embodiment, the polishing frame 27 has a matching groove at a corresponding position on the chain body 25. The chain body 25 is disposed in the groove of the polishing frame 27, so that the polishing frame 27 does not limit the chain body 25 when it moves, thereby improving the polishing effect on the chain body 25. The worktable 1 has a matching groove at a corresponding position on the L-shaped bracket 23. The L-shaped bracket 23 slides in the groove of the worktable 1, thereby limiting the L-shaped bracket 23 and adjusting the chain body. The tension of 25 improves the polishing effect on the chain body 25. Two sets of first polishing rollers 29 and second polishing rollers 210 are provided, symmetrically distributed inside the polishing frame 27 to enhance the polishing effect on the chain body 25 and improve the practicality of the device. A threaded rod 26 is rotatably connected inside the worktable 1, and an L-shaped bracket 23 is threadedly connected to the outside of the threaded rod 26. A second motor 28 is fixedly connected to the top of the worktable 1. The first polishing... Roller 29 is fixedly connected to the output end of the second motor 28. A water tank 213 is fixedly connected to the top of the worktable 1. A water pump 215 is fixedly connected to the top of the water tank 213. A water inlet pipe 216 is fixedly connected to the bottom of the water pump 215. The water inlet pipe 216 is located inside the water tank 213. A water outlet pipe 218 is fixedly connected between the water pump 215 and the cooling nozzle 217. The water outlet pipe 218 is located inside the grinding frame 27. A water inlet 214 is fixedly connected to the top of the water tank 213. The water flow is controlled by an L-shaped bracket. 23 is moved to straighten the chain body 25. The chain body 25 is then polished by the first polishing roller 29 and the second polishing roller 210. Cooling liquid is sprayed out by the cooling nozzle 217 and sprayed onto the chain body 25 for cooling. This shortens the time required to polish the chain body 25, improves the polishing effect, enhances the quality of the chain body 25, increases the polishing efficiency, and prevents harm to the health of workers.

[0025] Please see Figure 2 , Figure 6In this embodiment, the fixing component includes a mounting plate 31, which is fixedly connected to the front end of the collection box 219. A handle 32 is fixedly connected to the front end of the mounting plate 31. A square frame 33 is fixedly connected to the front end of the grinding frame 27. A locking block 34 is slidably connected inside the square frame 33 and engages with the inside of the mounting plate 31. An optical axis 35 is fixedly connected to the top of the locking block 34 and slidably connected inside the square frame 33. A spring 36 is fixedly connected between the locking block 34 and the square frame 33. A lever 37 is fixedly connected to the optical axis 35. The fixing component facilitates the fixing and disassembly of the collection box 219, enabling it to... To facilitate the collection and processing of dust and coolant after grinding, the bottom front of the locking block 34 is rounded, and the mounting plate 31 has a corresponding groove at the position of the locking block 34. The locking block 34 is engaged in the groove of the mounting plate 31. When the collection box 219 is inserted into the grinding frame 27, the rounded end of the locking block 34 moves the locking block 34 upward, compressing the spring 36. When the mounting plate 31 and the grinding frame 27 come into contact, the locking block 34 engages in the groove of the mounting plate 31, thus fixing the collection box 219 and improving the ease of processing the collection box 219.

[0026] During operation, when polishing the chain body 25, rotating the threaded rod 26 moves the L-shaped bracket 23, facilitating the straightening of the chain body 25 and bringing it to a taut state. Starting the first motor 21 drives the first transmission gear 22 to rotate, causing the chain body 25 to move in the direction of rotation of the first transmission gear 22. Simultaneously, starting the second motor 28 drives the first polishing roller 29 to rotate. Through the meshing of the second gear 212 and the first gear 211, the first polishing roller 29 and the second polishing roller 210 rotate in opposite directions. At this time, the chain body 25 passes between the first polishing roller 29 and the second polishing roller 210 for polishing. Simultaneously, starting the water pump 215 fills the water tank 213. The coolant inside is sprayed out from the cooling nozzle 217 through the water outlet pipe 218. The coolant sprays onto the chain body 25 for cooling, which shortens the time required for grinding the chain and improves work efficiency. At the same time, the chain body 25 is ground by two sets of first grinding rollers 29 and second grinding rollers 210, which makes the grinding effect better and improves the quality of the chain product. The dust after grinding falls into the inside of the collection box 219 and is filtered by the filter plate 220, separating the cooling water from the dust. When it is necessary to process the cooling water and dust inside the collection box 219, the lever 37 is pushed upward to move the locking block 34 away from the groove of the mounting plate 31, so that the collection box 219 can be pulled out from the inside of the grinding frame 27 through the handle 32, making it convenient to process the collection box 219.

[0027] Through the above steps, the L-shaped bracket 23 is moved to straighten the chain body 25. The first grinding roller 29 and the second grinding roller 210 grind the chain body 25. Cooling liquid is sprayed from the cooling nozzle 217 onto the chain body 25 for cooling. This shortens the grinding time required for the chain body 25, improves the grinding effect, enhances the quality of the chain body 25, increases the grinding efficiency, and prevents harm to workers' health. This solves the problem of low grinding efficiency and serious harm to workers' health.
