[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-4 This utility model provides a dust removal and cleaning device for the surface of plastic products, including a conveyor frame 1, a support 4 installed on the conveyor frame 1, a lifting component 7 provided on the support 4, the lifting component 7 being connected to a dust removal hood 3, another dust removal hood 3 being provided in the middle of the conveyor frame 1, the dust removal hood 3 on the lifting component 7 corresponding to the other dust removal hood 3 in the conveyor frame 1, a dust suction chamber 31 being provided inside the dust removal hood 3, a connecting plate 32 being bolted to the entrance of the dust suction chamber 31, a cleaning brush 33 being installed on the connecting plate 32, and conveyor belts 2 being provided on both the left and right sides of the dust removal hood 3 in the conveyor frame 1;

[0026] The dust suction chamber 31 of the dust removal hood 3 in the conveyor frame 1 is connected to the dust suction pipe 5, and the dust suction pipe 5 is connected to the external dust collection equipment;

[0027] The dust suction chamber 31 in the dust removal hood 3 of the lifting assembly 7 is connected to the telescopic tube 6, and the telescopic tube 6 is connected to the dust suction pipe 5.

[0028] Specifically, the plastic sheet is placed on the conveyor belt 2 and enters the equipment as the conveyor belt 2 moves. During the conveying process, the dust removal hoods 3, located in the middle of the conveyor frame 1 and corresponding to each other on the lifting assembly 7, clean both the top and bottom surfaces of the plastic sheet. As the plastic sheet moves, the cleaning brush 33 at the entrance of the dust removal hood 3 first physically scrubs the surface of the plastic sheet, loosening dust and impurities. Then, the dust and impurities scrubbed off are sucked into the suction chamber 31 by an external vacuum cleaner and discharged through the suction pipe 5. The suction chamber 31 of the dust removal hood 3 on the lifting assembly 7 is connected to the suction pipe 5 through the telescopic pipe 6, which also discharges the dust, completing the comprehensive cleaning of the plastic sheet.

[0029] The upper and lower corresponding dust hoods 3 can clean the upper and lower surfaces of the plastic board simultaneously, which greatly improves cleaning efficiency compared to single-sided cleaning, ensures no cleaning dead corners, and completely removes dust and impurities. At the same time, the physical brushing of the cleaning brush 33, combined with the suction power of the suction chamber 31, can make the cleaning effect more thorough. The telescopic tube 6 ensures that the dust hood 3 on the lifting assembly 7 can always be connected to the suction pipe 5 during the lifting process, ensuring that the suction function is not affected by height adjustment, making the equipment adaptable to plastic boards of different thicknesses and expanding its application range.

[0030] Furthermore, for accommodating plastic sheets of different thicknesses, please refer to [link / reference]. Figures 1-4 The lifting assembly 7 includes a motor 71, which is mounted on the bracket 4. The output end of the motor 71 is connected to a bidirectional threaded rod 72, which is rotatably mounted on the bracket 4. Parallel slide rods 73 are arranged on both sides of the bidirectional threaded rod 72, and the slide rods 73 are fixedly mounted on the bracket 4.

[0031] Both ends of the bidirectional threaded rod 72 are screwed with movable frames 74, and the bottom of the movable frames 74 at both ends of the bidirectional threaded rod 72 is hinged with connecting rods 75. The connecting rods 75 hinged at the bottom of the two movable frames 74 are arranged symmetrically to each other.

[0032] The connecting rod 75 is hinged to the connecting arm 76, and the connecting arm 76 is fixedly mounted on the dust collector 3.

[0033] Specifically, when it is necessary to clean plastic sheets of different thicknesses, the motor 71 installed on the bracket 4 is started. If it is necessary to lower the height of the dust cover 3 to accommodate thinner sheets, the motor 71 rotates in the forward direction, and the two movable frames 74 move towards the middle along the slide bar 73. If it is necessary to raise the height of the dust cover 3 to accommodate thicker sheets, the motor 71 rotates in the reverse direction, and the two movable frames 74 separate towards both ends along the slide bar 73. When the movable frames 74 move towards the middle, the tilt angle of the connecting rod 75 increases, pushing the connecting arm 76 and the dust cover 3 to move downward. During the movement of the movable frame 74, when the movable frame 74 separates towards both ends, the tilt angle of the connecting rod 75 decreases, pulling the connecting arm 76 and the dust cover 3 to move upward, thereby enabling the dust cover 3 to be raised and lowered.

[0034] By adjusting the rotation direction and number of revolutions of the motor 71, the lifting height of the dust cover 3 can be precisely controlled, thereby adapting to plastic sheets of different thicknesses and ensuring that the dust cover 3 maintains a suitable distance from the surface of the plastic sheet for effective cleaning. At the same time, by precisely controlling the lifting height of the dust cover 3, the cleaning brush 33 can make light contact with the sheet. The cleaning brush 33 is usually made of soft bristles with a certain degree of elasticity. When it comes into contact with the plastic sheet, it can follow the undulations of the sheet surface, reduce rigid resistance, and avoid causing significant obstruction to the movement of the sheet.

[0035] Working principle: The plastic sheet to be cleaned is placed on the conveyor belt 2 of the conveyor frame 1. Depending on the thickness of the plastic sheet, the motor 71 on the bracket 4 is started. The motor 71 drives the bidirectional threaded rod 72 to rotate, and the two movable frames 74 on both sides move synchronously towards or away from each other along the slide rod 73. If the sheet is thin, the motor 71 rotates in the forward direction, the movable frames 74 move towards the middle, the angle of the connecting rod 75 increases, and the dust cover 3 is pushed down to a suitable height. If the sheet is thick, the motor 71 rotates in the reverse direction, the movable frames 74 separate to both ends, the angle of the connecting rod 75 decreases, and the dust cover 3 is pulled up to a suitable height. By precisely controlling the number of rotations of the motor 71, the optimal cleaning distance between the upper and lower dust covers 3 and the surface of the plastic sheet is ensured, so that the cleaning brush 33 can lightly touch the surface of the sheet.

[0036] When the external vacuuming equipment is started, as the plastic sheet passes through the corresponding upper and lower dust hoods 3, the cleaning brush 33 at the inlet simultaneously performs physical scrubbing on the upper and lower surfaces of the sheet, loosening dust and impurities. The negative pressure generated by the vacuuming equipment is transmitted to the suction chamber 31 through the suction pipe 5 and the telescopic pipe 6, which quickly sucks in the scrubbed dust and impurities and discharges them from the equipment through the suction pipe 5. The telescopic pipe 6 automatically extends and retracts during the lifting and lowering of the dust hood 3 to ensure that the suction channel is always unobstructed. The cleaned plastic sheet is then sent out through another conveyor belt 2.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
