[0032] A dustproof shell 3 is fixedly connected between the tops of the fixed plates 1, and a cleaning brush roller 31 is arranged in the dustproof shell 3. The dustproof shell 3 is arranged to limit the floating space of the dust swept down, and when the cleaning brush roller 31 rotates to clean the glass cover plate, the movement of the glass cover plate on the top of the conveyor belt 12 can be limited by the cooperation of the pushing rod 14, thereby improving the cleaning effect thereof. The cleaning brush roller 31 is rotatably connected in the dustproof shell 3 through roller shafts symmetrically fixedly connected at both ends. A motor 2 32 for driving the corresponding cleaning brush roller 31 to rotate is bolted on the outer wall of the dustproof shell 3. A dust suction assembly 4 is installed on the top of the dustproof shell 3 for absorbing dust in the dustproof shell 3.

[0033] An adjusting baffle 22 is slidably connected inside the U-shaped plate 21, and a screw 23 threadedly connected to the corresponding U-shaped plate 21 is rotatably connected to one side of the adjusting baffle 22, and the free end of the screw 23 passes through the outer side of the U-shaped plate 21 and is fixedly connected to a hand wheel 24.

[0034] Support frames 19 are symmetrically welded on both sides of the bottom between the fixing plates 1 to support the two fixing plates 1 and increase the connection stability between the two.

[0035] Embodiment 2:

[0036] In view of the problem that the dust removed in the prior art cannot be collected during the dust removal process, so that the dust is easily adsorbed on the surface of the glass cover again, thereby reducing the dust removal effect, the following solution can be used to solve the problem:

[0037] See also Figure 3 - Figure 5 As shown, the dust collection assembly 4 in this embodiment includes a collection box 41, a dust collection pipe 42, a dust collection fan 43, a through slot 44 and a dust filter 45. The top of the dustproof shell 3 is fixedly connected to the side away from the motor 2 32 with the collection box 41 for centralized collection of cleaning dust, and the dust collection pipe 42 is fixedly connected between the collection box 41 and the dustproof shell 3. The top side of the collection box 41 is bolted with the dust collection fan 43, and the top of the collection box 41 is provided with a through slot 44 corresponding to the air suction port of the dust collection fan 43. The air in the collection box 41 is extracted by the dust collection fan 43 to form a negative pressure state inside it, and the dust collection pipe 42 is used to connect the inside of the collection box 41 with the inside of the dustproof shell 3 to realize the extraction of dust in the dustproof shell 3. A dust filter 45 is fixedly installed in the through slot 44 to avoid the problem of dust being discharged with the discharge of air.

[0038] A transmission rod 46 is rotatably connected inside the collection box 41, and one end of the transmission rod 46 is fixedly connected to a cleaning brush 47 that is slidably connected to the dust filter 45. The cleaning brush 47 is driven to rotate by rotating the transmission rod 46 to clean the dust filter 45 to prevent dust from clogging the mesh of the dust filter 45, thereby reducing the problem of dust absorption effect. The free end of the transmission rod 46 passes through the outside of the collection box 41 and is fixedly connected to a driven bevel gear 48. The free end of the roller shaft on one side of the cleaning brush roller 31 passes through the outside of the dust shell 3 and is fixedly connected to a driving bevel gear 33, and the driving bevel gear 33 and the driven bevel gear 48 are meshed with each other. Through the meshing driven bevel gear 48 and the driving bevel gear 33, the cleaning brush roller 31 rotates and simultaneously drives the transmission rod 46 to rotate, thereby realizing the rotation of the cleaning brush 47.

[0039] An air outlet plate 15 is fixedly connected between the fixed plates 1 and located directly below the cleaning brush roller 31, and the top of the air outlet plate 15 is slidably connected to the inner side wall of the conveyor belt 12. The air outlet plate 15 is provided to increase the supporting effect of the conveyor belt 12 below the cleaning brush roller 31, while preventing the conveyor belt 12 from being deformed and bent by the force of the cleaning brush roller 31, which may easily lead to the problem of the glass cover plate being transported being broken. A plurality of air outlet slots 16 are provided through the top of the air outlet plate 15, and through holes 17 are densely provided on the conveyor belt 12. An air pipe 18 is fixedly connected between the air outlet plate 15 and the air outlet of the dust suction fan 43. The air discharged from the dust suction fan 43 is injected into the air outlet plate 15 through the air pipe 18, and enters the bottom of the dustproof shell 3 again from the air outlet slots 16 and the through holes 17, so that the gas in the dustproof shell 3 is circulated from bottom to top, further enhancing the dust absorption effect.

[0040] The working process and principle of the utility model are as follows:

[0041] During use, the utility model adjusts the distance between the two adjustment baffles 22 according to the size of the glass cover plate, and the hand wheel 24 drives the screw rod 23 to rotate to achieve the distance adjustment between the two adjustment baffles 22, thereby facilitating the stacking of glass cover plates of different sizes, and then neatly stacking the glass cover plates between the two U-shaped plates 21;

[0042] The starting motor 13 drives the corresponding rotating roller 11 to rotate, and the rotating roller 11 drives the conveyor belt 12 to rotate. The conveyor belt 12 cooperates with multiple push rods 14 on the outer wall to push the glass cover plates in contact with the conveyor belt 12 to move, thereby realizing continuous one-by-one transportation. At the same time, the starting motor 2 32 drives the cleaning brush roller 31 to rotate rapidly in the same direction as the conveyor belt 12, and cleans the dust on the surface of multiple continuously transported glass cover plates under the blocking cooperation of the push rod 14;

[0043] At the same time, the dust suction fan 43 is started to extract the air in the collection box 41, so that a negative pressure state is formed inside the collection box 41, and the dust suction pipe 42 is used to connect the inside of the collection box 41 with the inside of the dustproof shell 3, so as to extract the dust in the dustproof shell 3, and the dust in the exhaust air is blocked by the dust filter 45. The exhaust air enters the air outlet plate 15 through the air pipe 18, and then enters the bottom of the dustproof shell 3 again through the air outlet slot 16 and the corresponding through hole 17, so as to realize the circulation flow of the gas in the dustproof shell 3 from bottom to top, thereby enhancing the dust absorption effect;

[0044] When the cleaning brush roller 31 rotates, the driven bevel gear 48 and the driving bevel gear 33 are meshed, so that the cleaning brush roller 31 rotates and the transmission rod 46 is synchronously driven to rotate. The transmission rod 46 drives the cleaning brush 47 to rotate, so as to clean the dust filter 45 to prevent dust from clogging the mesh of the dust filter 45 and reducing the flow effect of the gas in the dustproof shell 3.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
