[0015] Beneficial effects of the present invention:

[0016] (1) The present invention provides a push rod, a guide rod, a mounting frame and other structures. The pressure roller and the sanding roller are respectively mounted on two mounting frames. The bottom heights of the pressure roller and the sanding roller match each other. The mounting frame can move upward along the guide rod. The plate to be processed is placed on the conveyor belt and sent into the shell. One end of the plate contacts the push rod. The push rod can first push the height of the pressure roller to increase. After the push rod is separated from the pressure roller, the pressure roller will automatically drop and contact the surface of the plate to position the plate. At this time, the height of the pressure roller and the sanding roller changes. The sanding roller sands the plate. Even if the thickness of the subsequent plate changes, the height of the pressure roller and the sanding roller will be adaptively adjusted to complete the sanding of the plate.

[0017] (2) The present invention provides a sealing cylinder, a connecting block, a first piston plate, a water tank, a second piston plate and other structures. After sanding, there will be many debris on the surface of the plate. When each plate is sanded, the connecting block and the first piston plate will rise under the action of the push rod, and the rising height each time is the same. Under the action of air pressure, the aqueous solution in the water tank is sent into the water distribution plate to wet the wiping sponge. The height of the wiping sponge is fixed, and the surface of the plate is wiped, which is convenient for subsequent processing.

[0018] (3) The present invention provides a collecting box, a scraping plate, a dryer and other structures. When the scraping rod moves, it can also scrape off the debris on the wiping sponge. The debris and waste liquid fall onto the conveyor belt. Finally, under the action of the scraping mechanism, the collecting box collects the waste liquid and debris, and the dryer can dry the conveyor belt to ensure that the conveyor belt is dry and avoid the influence of moisture on the plate.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Initially, the heights of the pressure roller 9 and the sanding roller 10 are relatively low. As the push rod 5 moves, the pressure roller 9 and a mounting frame 7 rise. Under the action of the connecting block 19, the other mounting frame 7 and the sanding roller 10 rise. When the pressure roller 9 moves to the highest point of the push rod 5, under the action of gravity, the pressure roller 9 gradually descends and contacts the surface of the plate to position the plate, and then the sanding roller 10 also descends to a certain height to sand the plate. Even if the thickness of the subsequent plates is different, the height to which the pressure roller 9 and the sanding roller 10 descend is changed based on the thickness of the plate. Therefore, efficient sanding can be performed without stopping the machine, thereby ensuring production efficiency. It is worth mentioning that a motor is installed on a mounting frame 7 to drive the sanding roller 10 to rotate, which is not shown in the figure and will not be described here.

[0031] See also Figure 2 , 36. Two first fixing rods 13 are fixed to the inner surface of the top wall of the shell 1, and a water tank 14 is fixed to the bottom of the two first fixing rods 13. Two second fixing rods 16 are fixed to the bottom wall of the water tank 14, and a water distribution plate 17 with a hollow structure is fixed to the bottom ends of the two second fixing rods 16.

When the mounting frame 7 descends, the first piston plate 23 and the second piston plate 25 are reset, and the external air enters the bottom of the second piston plate 25 through the air inlet pipe 21, ensuring the air pressure balance and facilitating the next squeezing out of the aqueous solution.

[0033] See also Figure 1 , and also includes a collecting box 26 with an open top, the collecting box 26 is located below the discharge port 2, and a dryer 28 is installed on the inner surface of the bottom wall of the shell 1; the collecting box 26 is used to collect waste liquid and debris, and the dryer 28 dries the conveyor belt 4.

[0034] See also Figure 7A scraping mechanism 27 is fixed on the top of the collecting box 26, and the scraping mechanism 27 includes a hollow plate 2701. A scraping plate 2703 is movably arranged on the top wall of the hollow plate 2701. The top of the scraping plate 2703 is chamfered, and the bottom of the scraping plate 2703 is connected to a second spring 2702, and one end of the second spring 2702 is connected to the bottom wall of the hollow plate 2701; the scraping plate 2703 is always in contact with the conveyor belt 4 under the action of the second spring 2702, and scrapes the waste liquid and debris on the surface of the conveyor belt 4 to ensure cleanliness. The chamfer of the scraping plate 2703 is to facilitate its collection into the hollow plate 2701 after contacting with the push rod 5.

[0035] The working principle of the present invention is as follows: the plate to be processed is placed on the side of the conveyor belt 4 close to the feed port 3, and one side of the plate contacts the push rod 5, only one plate is placed between two adjacent push rods 5, and the distance between the two adjacent push rods 5 can be adjusted according to actual needs. The conveyor belt 4 sends the plate into the shell 1, and the push rod 5 will first contact the pressure roller 9. Initially, the heights of the pressure roller 9 and the sanding roller 10 are relatively low. As the push rod 5 moves, the pressure roller 9 and a mounting frame 7 rise. Under the action of the connecting block 19, the other mounting frame 7 and the sanding roller 10 rise. When the pressure roller 9 moves to the highest point of the push rod 5, under the action of gravity, the pressure roller 9 gradually descends and contacts the surface of the plate to position the plate. Then the sanding roller 10 also descends to a certain height to sand the plate. Even if the thickness of the plate subsequently placed is different, the height of the pressure roller 9 and the sanding roller 10 is changed based on the thickness of the plate. Therefore, efficient sanding can be performed without stopping the machine, thereby ensuring production efficiency.

[0036] When the two mounting frames 7 are raised, the first piston plate 23 is raised by the piston rod 22, squeezing the air in the sealing cylinder 12, and the gas enters the water tank 14 through the air outlet pipe 15. The air pressure in the water tank 14 increases, the second piston plate 25 descends, and the first spring 24 is stretched, so that the aqueous solution in the water tank 14 is squeezed out through the water outlet pipe 20, and the aqueous solution enters the water distribution plate 17 to moisten the wiping sponge 18 and wipe and remove dust from the sanded plate. The descending stroke of the second piston plate 25 is fixed, and the amount of water squeezed out each time is fixed, which reduces the waste of the aqueous solution. After the sanding is completed, the mounting frame 7 descends, and the first piston plate 23 and the second piston plate 25 are reset. Under the action of negative pressure, external air enters the bottom of the second piston plate 25 through the air inlet pipe 21 to ensure air pressure balance and facilitate the next squeezing out of the aqueous solution. The first one-way valve prevents the gas and the aqueous solution from being discharged from the air inlet pipe 21, and the second one-way valve allows the aqueous solution to be discharged only after pressurization.

[0037] After wiping, impurities will adhere to the surface of the wiping sponge 18. When the push rod 5 passes through the wiping sponge 18, it squeezes the wiping sponge 18 to scrape off the debris and squeeze out the waste liquid, which then falls on the conveyor belt 4. As the conveyor belt 4 moves, the waste liquid and debris fall into the collecting box 26. Under the action of the scraping mechanism 27, the conveyor belt 4 and the push rod 5 are further cleaned. Finally, the dryer 28 dries the conveyor belt 4.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
