[0041] Working principle:

[0042] The return water tank 11 in the main structure 1 is horizontally arranged on the ground, and the copper foil can be tiltedly input into the main structure 1 through one of the second guide roller groups 23 on the first guide frame 21 in the guide structure 2; and the copper foil is attached to the first guide roller group 16 on the first bearing rod 13 supported by the bearing frame 12, and is attached to the first guide roller group 16 on the upper side of the return water tank 11; and the copper foil is located between the roller column 232 on the roller frame 231 and the scraper 34;

[0043] Then the copper foil will pass through the second guide roller set 23 on the second guide frame 22, and the copper foil needs to pass through the second guide roller set 23 on the second guide frame 22 in an alternating manner. After being guided by the second guide roller set 23, the copper foil will fit with the first guide roller set 16 on the other side above the return water tank 11 to form a U-shaped routing line, move to the input end, and be guided to the output by another second guide roller set 23 on the first guide frame 21;

[0044] The nozzle 33 installed by the bearing assembly 31 in the cleaning structure 3 is connected to the water supply pipe, that is, water is sprayed toward the copper foil. As the copper foil moves and tilts, the water flows downward with gravity and moves toward the scraper bar 34 with the movement of the copper foil. Then, the water flows to the return water tank 11 through the shielding and tilt of the scraper bar 34. The copper foil surface is washed and scraped for multiple times to achieve the cleaning effect. The equipment occupies a small area.

[0045] The conveying inclination angle of the copper foil can be adjusted by the first transfer claw 15 on the first flip arm 14. The inclination angle of the first guide roller and the second guide roller group 23 and the width of the copper foil can be adjusted by the first transfer claw 15 to dock the first guide roller group 16 and the second guide roller group 23.

[0046] The installation angle of the first connecting arm 311 on the first transfer claw 15 is adjusted by the second bolt 313 and the second nut 314 to assist in adjusting the height of the first connecting frame 312 and the distance between the nozzle 33 or the scraper 34 and the first guide roller group 16; the installation height of the first connecting frame 312 on the first connecting arm 311 can also be adjusted by the second bolt 313 and the second nut 314, and the front and rear spraying angles of the nozzle 33 and the contact angle of the scraper 34 with the copper foil can be adjusted by the two ends of the first connecting frame 312 being relatively rotatable; the left and right spraying angles of the nozzle 33 can be adjusted on the first connecting frame 312 by the spray arm 32 and fixed by the second bolt 313 and the second nut 314;

[0047] When the copper foil needs to be cleaned on both sides, the first guide roller group 16 on the first bearing rod 13 is installed to be inclined to the same side through the first transfer claw 15, and the rollers 232 are oriented in the same direction, so that double-sided inclination can be achieved by guiding with the help of the second guide roller group 23 on the second guide frame 22.
