[0002] Polishers, also known as grinders, are often used for mechanical grinding, polishing, and waxing. Their operating principle is this: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. The disc and polishing compound work together to rub against the surface being polished, removing paint contamination, oxide layers, and shallow scratches. The disc's speed typically ranges from 1500 to 3000 rpm, often with continuously variable speeds, allowing for adjustment during application.

[0003] The flexible metal plate polishing and grinding equipment disclosed in Chinese patent CN105538102B utilizes a large-area vertical sanding belt to polish and grind the surface of the metal plate.

[0015] To achieve the above object, the present invention provides the following technical solution: a polishing method for elevator landing door processing, comprising the following steps:

[0016] First, the plate to be processed is placed on the conveyor belt in the polishing and grinding box, and the motor drives the rotating roller in the limit plate frame to rotate, which drives the driving belt connected to the rotating roller to rotate, so that the driving belt slides in the limit plate frame. 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 tank below. The coolant collected in the water tank is processed by the filtering component so that the coolant can be used again.

[0017] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0018] 1. The rotating roller drives the sleeved drive belt to rotate along the inner wall of the limit plate frame, driving the polishing roller under the drive belt to move along the side of the plate to be processed to polish the side of the plate to be processed. 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 drive belt can drive the polishing roller to perform circular motion along the side of the plate to be processed, and the side polishing work can be completed at one time without adjusting the position or direction of the polishing roller multiple times, reducing the time wasted due to frequent changes in processing positions or procedures.

[0019] 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 and effectively inhibit the spread 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 bevel block on the lower surface of the limit plate frame. When the sliding column falls from the surface of the limit bevel block, the polishing roller Vibration is generated to shake off impurities attached to the surface of the polishing roller. Vibration removes impurities to keep the surface of the polishing roller clean and ensure consistent polishing quality. Impurities are automatically removed by vibration, which reduces downtime and improves work efficiency. The coolant sprayed on the plate to be processed is collected by the water tank and the collected coolant is processed by the filter component to separate the impurities mixed in the coolant so that the treated coolant can be sprayed on the plate to cool it down. The polishing process usually requires a large amount of coolant. Recycling can greatly reduce the consumption of fresh water resources and reduce water costs.

[0020] 3. The roller cover pushes the driving push rod on one side to move. The pushing plate at the bottom end of the driving push rod will slide along the inner wall of the water tank, pushing the impurities accumulated on the surface of the filter plate 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, 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 vibrate the polishing roller 207 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 lower surface of the lifting plate 214 is provided with a reset spring piece 217, and the reset spring piece 217 is sleeved on the limiting sleeve 213.

[0043] Specifically, initially, the top of the limiting sleeve 213 is level with the top of the sleeved limiting shaft 212, and the driving motor 211 in the mounting frame 210 drives the polishing roller 207 in the roller cover 218 to rotate to grind the side of the plate 208 to be processed, and the sleeved driving belt 204 is driven to rotate in the limiting plate frame 201 by rotating roller 1 203. During the rotation of the driving belt 204, the sliding block 206 slides along the limiting slide groove 205 on the limiting plate frame 201, and at the same time drives the vibration assembly and cooling assembly on the polishing roller 207 to move.

Since the driving push rod 1 306 and the driving push rod 2 307 are staggered at both ends of the pushing plate 305, when the roller cover 218 pushes the driving push rod When the push rod 1 306 resists the other side, the polishing roller 207 continues to move from the gap between the driving push rod 1 306 and the plate 208 to be processed, and polishes the side of the plate 208 to be processed. 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.
