Adjust the angle of the cross so that the cleaning roller and the coating roller are in close contact with the aluminum foil, and then lock the fixing plate and the drum through the locking screw. At this time, the cross and the drum are relatively fixed, and the coating roller is on the surface of the aluminum foil. Apply cleaning solution, the cleaning roller completes the cleaning work, and at the same time clean the pressing block and then wipe the surface of the aluminum foil, and finally output the aluminum foil to complete the cleaning of the aluminum foil. After working for a period of time, the drum rotates 180 degrees, and another group of cleaning rollers and coating rollers continue to complete the cleaning work. The staff can replenish the coating rollers that have used the cleaning solution in time.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

In order to illustrate the technical solutions of the present invention, the following specific embodiments are used for description.

As shown in FIG. 1 , the aluminum foil cleaning device includes a support table 1 , a drive motor 2 , a stepping motor 3 and a gear box 4 arranged outside the support table 1 , and the support table 1 is provided with a rotating drum 5 and a gear box 4 . The traction rollers 6 are located under the two sides of the rotating drum 5. The two sides of the rotating drum 5 are symmetrically provided with a cross 7. The cross 7 includes two crossed struts, and the struts can rotate around the center of the end face of the rotating drum 5. , a rotatable coating roller 71 and a cleaning roller 72 are arranged at intervals between the ends of the crosses 7 on both sides, and a fixed plate 73 is connected between the two supporting rods corresponding to the coating roller 71, and the two corresponding cleaning rollers 72. A fixing plate 73 is also connected between the supporting rods, the fixing plate 73 is in contact with the surface of the drum 5, and the fixing plate 73 and the drum 5 are locked by locking nails 74. A reversing roller 8 is arranged at the lower part of the room, and an output platform 9 and a fixed head 91 are arranged on the outer side of the traction roller 6 at the rear. The fixed head 91 is located above the output platform 9, and the lower end of the fixed head 91 is fixed with a cleaning pressure. Block 92, the bottom surface of the cleaning pressure block 92 is at the same height as the top of the traction roller 6, the drive motor 2 is linked with the traction roller 6 through the gear box 4, and the stepping motor 3 is connected with the traction roller 6 through the gear box 4. The drum 5 is linked to control the 180-degree forward and reverse rotation of the drum.

In the present invention, as shown in Figure 2, the aluminum foil passes through the first traction roller, bypasses the reversing roller, and then passes through the second traction roller, and then enters the output platform, and is led out between the cleaning pressure block and the output platform, and the angle of the cross is adjusted. , so that the cleaning roller on one of the poles presses the aluminum foil on one traction roller, and the coating roller on the other pole presses the aluminum foil on the other traction roller, and then fixed by the locking nail, at this time the cross Relatively fixed with the drum, the traction roller rotates to drive the aluminum foil to advance, and the coating roller applies cleaning liquid to the surface of the aluminum foil, and the cleaning roller completes the cleaning work.
