When the driving belt slides along the inner wall of the limit plate frame, it will drive the sliding block under the driving belt to slide along the limiting slide groove at the same time. When the sliding block slides along the limiting slide groove, it drives the polishing roller below to polish along the side of the plate to be processed. At the same time, as the polishing roller moves, the cooling component will spray coolant to cool the plate to be processed being polished. When the polishing roller moves quickly to the rounded corners around the limit plate frame, the vibration component will make the polishing roller vibrate during the movement, and the impurities attached to the polishing roller will be shaken off and collected in the water storage tank below.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1.

The polishing roller can evenly remove burrs, scratches and oxide layers on the side of the metal plate, making the side smoother and improving the appearance quality. The driving belt can drive the polishing roller to move in a circle along the side of the plate to be processed, and the polishing work of the side can be completed at one time. There is no need to adjust the position or direction of the polishing roller multiple times, which reduces the time wasted due to frequent changes in processing positions or procedures.

[0017] 2. The driving gear follows the polishing roller to rotate under the gear rack. When the polishing roller moves with the plate to be processed, the rotation of the driving gear will drive the bevel gear 2 at the other end to drive the meshing bevel gear 1 to rotate at the same time. The coolant will be discharged from the outlet pipe and sprinkled on the polishing part of the plate to be processed. Spraying coolant can quickly take away the heat. Spraying coolant can effectively inhibit the diffusion of dust, take away dust and particles, and keep the working area clean. The sliding columns on both sides of the mounting frame will slide along the limit inclined block on the lower surface of the limit plate frame. When the sliding column falls from the surface of the limit inclined block, the polishing roller Vibration is generated to shake off impurities attached to the surface of the polishing roller. Vibration to remove impurities can keep the surface of the polishing roller clean and ensure consistent polishing quality. Impurities are automatically removed through vibration, which reduces downtime and improves work efficiency. The coolant sprayed on the plate to be processed is collected through a water tank and the collected coolant is processed through a filter component to separate the impurities mixed in the coolant, so that the treated coolant can be sprayed on the plate to be processed for cooling. The polishing process usually requires a large amount of coolant, and recycling can greatly reduce the consumption of fresh water resources and reduce water costs.

[0018] 3. The driving push rod on one side is pushed to move by the roller cover. The push plate at the bottom of the driving push rod will slide along the inner wall of the water tank, and the impurities accumulated on the surface of the filter plate will be pushed into the storage box on one side. By pushing away the impurities, the permeability of the filter plate can be maintained, the water flow can be kept unobstructed, and the stability of the circulation system can be maintained, thus ensuring the smooth progress of the entire process and the efficient operation of the water circulation system.

At the same time, as the polishing roller 207 moves, the cooling component sprays coolant to cool the plate 208 to be processed. When the polishing roller 207 moves quickly to the rounded corners around the limiting plate frame 201, the vibration component will make the polishing roller 207 vibrate during the movement, and the impurities attached to the polishing roller 207 will be shaken off and collected in the water tank 301 below. The coolant collected in the water tank 301 is processed by the filtering component so that the coolant can be used again.

At the same time, the limiting sleeve 213 slides downward from the top of the limiting rotating shaft 212, pushing the polishing roller 207 at the bottom end of the limiting sleeve 213 to move downward. When the sliding column 216 passes through the lower surface of the limiting inclined block 209, the compressed reset spring piece 217 pushes the lifting plate 214 to slide upward along the inner wall of the mounting frame 210 under the reaction force, so that the limiting sleeve 213 slides along the sleeved limiting rotating shaft 212 and returns to the initial state, causing the polishing roller 207 to vibrate and shake off the impurities attached to the surface of the polishing roller 207.

When the polishing roller 207 moves from one end of the rotating roller 2 302 to one end of the other rotating roller 2 302, the roller cover 218 on the polishing roller 207 will contact the driving push rod 2 307 at the other end of the push plate 305, and push the push plate 305 to slide along the inner wall of the water tank 301 again.
