A baffle 2 is provided on the rear side of the mounting plate 10 and is fixedly connected to the inside of the cleaning housing 1. During operation, the nozzles 23 rinse the cover plate. The wastewater after rinsing flows out from the water outlet pipe at the bottom of the device. The baffle 2 is in contact with the first feeding wheel 3 and the second feeding wheel 4 located inside the baffle 2 to prevent the nozzles 23 from spraying water to the rear of the cleaning housing 1 and affecting the drying of the cover plate.

[0029] It should be noted that this utility model is a sheet molding compound conveying device with a dust removal mechanism. When in use, the motor drives the third worm gear 21 to rotate, and the third worm gear 21 drives the first feeding wheel 3 to rotate. Then, the cut and polished cover plate can be erected by the conveyor belt and vertically fed into the device through the first feeding wheel 3 on the front side of the cleaning housing 1. At this time, the nozzle 23 sprays water curtain to wash the surface of the cover plate. While the third worm gear 21 rotates, it drives the rubber wheel 5 to rotate via the first worm gear 8 to transport the cover plate during rinsing. At the same time, the first gear 7 drives the second gear 14 to rotate. The second rotating shaft 13 is slidably connected to the rotating drum 12, and the outer side of the second rotating shaft 13 is formed with protrusions. The second gear 14 drives the soft brush roller 11 to rotate via the second rotating shaft 13 to brush the surface of the cover plate. While the second rotating shaft 13 rotates, the second worm gear 18 drives the mounting plate 10 to move up and down via the cam 19. At this time, the mounting plate 10 drives the soft brush roller 11 to move up and down via the rotating drum 12, so that the soft brush rollers 11 on both sides of the cover plate rotate and shake up and down to clean the front and back surfaces of the cover plate at the same time, which improves the cleaning effect of the device on the cover plate. During cleaning, the cover plate stands inside the cleaning housing 1, so that the sewage generated by the spray nozzle 23 and the cleaning of the soft brush roller 11 falls into the bottom of the cleaning housing 1 with the water flow under the action of gravity, preventing sewage from staying on the surface of the cover plate during cleaning, thus improving the cleaning effect of the device.

[0030] When the cleaned cover plate is conveyed by the first feeding wheel 3 to the positions of the first guide wheel 24 and the second guide 25, the air supply pipe 26 starts to work. The drive device of the air supply pipe 26 is fixedly connected to the outside of the cleaning housing 1. The drive device is a mature existing technology and will not be described in detail here. The air outlet of the air supply pipe 26 is set at an angle. When working, the air supply pipe 26 blows out warm air to blow away the residual moisture on both sides of the cover plate at an angle downwards. The first guide wheel 24 supports the cover plate that is transported out by the first feeding wheel 3 on the rear side inside the cleaning housing 1 to prevent the cover plate from tilting. At this time, the air supply pipe 26 dries the upper half of the cover plate. The worm gear 20 drives one of the second guides 25 to rotate through the fourth worm wheel. Then, the two second guides 25 contact the dried part of the top of the cover plate and send the cover plate out of the cleaning housing 1. At the same time, the air supply pipe 26 below the second guide 25 dries the lower half of the cover plate. The upright cover plate is supported and transported by the first guide wheel 24 and the second guide 25, while the air supply pipe 26 dries the cover plate in sections to prevent residual moisture on the surface of the cleaned cover plate from affecting the subsequent processing of the plastic sheet.
