[0020] Working principle of the above technical solution: During use, the user places the cut copper strip or copper foil for guiding on the top of the hollow conveyor belt 12. At this time, the servo motor 13 rotates to drive the conveyor roller 10 to rotate, and drives the hollow conveyor belt 12 to rotate, thereby causing the copper foil to be conveyed. Then, the output end of the air pump 3 blows air into the blowing head 15 through the air outlet pipe 4, and the air flow of the blowing head 15 gently blows on the outer surface of the copper foil to initially blow off copper chips and copper powder. Then, the copper foil moves to the opposite side of the hollow roller 7 through the guide plate 25 and moves under the clamping of the sponge roller sleeve 17. At this time, the input end of the air pump 3 sucks air from inside the filter box 2, causing a negative pressure to form inside the filter box 2. The air flow enters the inside of the hollow roller 7 through the sponge roller sleeve 17, adsorbing the copper powder and copper chips on the outside of the copper foil. The air flow enters the inside of the hollow roller 7 through the hollow holes of the hollow roller 7, and then enters the inside of the filter box 2 through the connecting pipe 6 and the suction pipe 5. After being filtered by the filter plate 22 of the filter box 2, the air flow forms a cycle through the air pump 3, facilitating the cleaning of the outside of the copper foil. The input end of the water pump 8 is connected to a water source, and the water flow is pumped into the atomizing head 16, and the small-flow water flow is ejected through the atomizing head 16 for flushing to wash away the remaining copper foil and copper powder on the outside of the copper foil. Finally, the water is absorbed by the water-absorbing sponge roller 23, and in cooperation with the air flow heating of the blower 20 and the resistance heating wire 19, the water on the outside of the copper foil is blown off, facilitating the heating of the water-absorbing sponge roller 23 and the absorption of the water flow by the water-absorbing sponge roller 23. The overall structure is stable, facilitating cleaning and washing. By setting the blower 20, when the blower 20 is started, the air flow is blown towards the resistance heating wire 19, and the resistance heating wire 19 heats the air flow and blows it towards the copper foil. In cooperation with the water-absorbing sponge roller 23, the outside of the copper foil is heated, and in cooperation with the water-absorbing sponge roller 23 to absorb the water vapor, facilitating the drying of the water flow. In addition, the water-absorbing sponge roller 23 can be set in multiple groups to clamp and roll and adsorb relative to the hollow conveyor belt 12 and the copper foil, facilitating the response to a relatively fast cleaning process.

[0021] In another embodiment, as Figures 1 - 4 shown, multiple conveyor rollers 10 located inside the box body 1 are fixed to the inner wall of the box body 1 through shaft seats, and one conveyor roller 10 located outside both ends of the box body 1 is fixed to the outside of both ends of the box body 1 through a bearing penetrating the bracket. The conveyor rollers 10 are linearly and evenly distributed inside both ends of the box body 1.

[0022] The conveyor roller 10 cooperates with the hollow conveyor belt 12 to transport the copper foil from the outside of the box body 1 to the other side of the box body 1, facilitating the conveyance and movement of the copper foil, improving the use effect of the structure, and facilitating the cooperation with the conveying operation.

[0023] In another embodiment, as Figures 1 - 3 shown, the servo motor 13 is fixedly installed on the outside of the box body 1 through a bracket, and the hollow conveyor belt 12 extends to the outside of both ends of the box body 1 through the communication port 14.

[0024] The servo motor 13 provides a rotating action for the conveyor roller 10 to drive the hollow conveyor belt 12 to rotate, and drives the structure to operate, facilitating the driving of the conveyor belt.

[0025] In another embodiment, as Figures 1 - 4 shown, both ends of the two air blowing heads 15 are fixed to the inner wall of the box body 1, and the two air blowing heads 15 are respectively located at the top and bottom of the upper end of the hollow conveyor belt 12. Both ends of the two atomizing heads 16 are fixed to the inner wall of the box body 1, and the two atomizing heads 16 are respectively located at the top and bottom of the upper end of the hollow conveyor belt 12.

[0026] The air blowing head 15 and the atomizing head 16 spray air flow and water flow on the outer side of the copper foil respectively, facilitating cleaning. When the water flow is sprayed out through the atomizing head 16, it will carry away the copper powder and copper chips falling on the bottom of the inner cavity of the box body 1 by flowing. The copper powder in the air flow is filtered through the discharge pipe 11 in cooperation with the filter plate 22, facilitating the collection and recovery of the copper powder and copper chips, and facilitating use.

[0027] In another embodiment, as Figure 3 shown, the opposite ends of the two guide plates 25 are located on the opposite sides of the hollow conveyor belt 12. The top of the guide plate 25 is at the same horizontal plane as the upper end of the hollow conveyor belt 12. The guide plates 25 are located on both sides of the middle part of the hollow roller 7.

[0028] The guide plates 25 provide support for the copper foil, preventing the copper foil from falling obliquely, facilitating its stability inside the hollow roller 7, and facilitating the adsorption of copper powder on the outside.

[0029] In another embodiment, as Figures 1 - 4 shown, the sealed bearing 24 is movably sleeved inside the hollow roller 7. The bottom of the filter box 2 is fixedly installed on the top of the box body 1. One side of the filter box 2 is movably equipped with a sealed door. The input end of the air pump 3 is connected through a pipeline to the bottom side of the filter box 2, and the input end of the air pump 3 and the suction pipe 5 are diagonally connected and distributed at the top and bottom of the filter box 2.

[0030] The input end of the air pump 3 sucks air from the inside of the filter box 2, making the inside of the filter box 2 form a negative pressure. The air flow enters the inside of the hollow roller 7 through the sponge roller sleeve 17, adsorbing the copper powder and copper chips outside the copper foil. The air flow enters the inside of the hollow roller 7 through the hollow holes of the hollow roller 7, and then enters the inside of the filter box 2 through the connecting pipe 6 and the suction pipe 5. After being filtered by the filter plate 22 of the filter box 2, the air flow forms a cycle through the air pump 3, facilitating the cleaning of the outside of the copper foil, facilitating the interception of copper powder in the air flow, and using the principle of air adsorption and dust collection to perfectly clean the copper powder and copper chips, improving the cleaning efficiency.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
