[0032] Reference Figure 3-Figure 5The outer side of the bracket 13 is fixedly connected to a motor 14, and the inner side of the bracket 13 is rotatably connected to two gears 15, and the two gears 15 are meshed with each other, one of the gears 15 is fixedly connected to the output end of the motor 14, and the two gears 15 are fixedly connected to the side away from the motor 14 with a brush roller 16. By driving the motor 14 and in the meshing state of the two gears 15, the two brush rollers 16 can be rotated in opposite directions at the same time, so that the opposite side of the aluminum foil roll 28 and the copper foil roll 29 can be cleaned to prevent impurities from being adsorbed and accumulated on the side of the aluminum foil roll 28 and the copper foil roll 29 that need to be composited, thereby improving the composite effect and the finished product quality of the copper-aluminum composite foil. Under the action of the displacement component 30, the bracket 13 can be moved, and at this time, the two brush rollers 16 can be respectively in contact with the released parts of the aluminum foil roll 28 and the copper foil roll 29, thereby improving the cleaning effect.

[0034] Reference Figure 3-Figure 5 By driving the vacuum pump 17, the air inlet pipe 18 can drive the cover body 19 to suck the cleaned impurities into the collection box 20. When the impurities enter, the impurities entering can be filtered through the filter plate 21 to prevent the impurities from being discharged, which can improve the avoidance of environmental pollution.

Two limit blocks 24 are fixedly connected to the outside of the two movable plates 5, and two limit grooves 25 are provided inside the two shells 3. The limit blocks 24 are slidably connected to the middle of the limit grooves 25.

[0037] Reference Figure 6 Four slide grooves 23 are provided on the side of the two shells 3 away from the bracket 2, and the clamping plate 7 is slidably connected to the middle of the slide groove 23. The slide groove 23 can provide a movable position of the clamping plate 7 in the middle of the shell 3, so that the clamping plate 7 can contact the aluminum foil roll 28 and the copper foil roll 29, so as to clamp the aluminum foil roll 28 and the copper foil roll 29 from the inside. The eight clamping plates 7 are fixedly connected to the far side with rubber pads 8, four of which are in contact with the inner wall of the aluminum foil roll 28, and the other four rubber pads 8 are in contact with the inner wall of the copper foil roll 29. The rubber pads 8 can improve the clamping effect of the aluminum foil roll 28 and the copper foil roll 29, and at the same time avoid scratching the aluminum foil roll 28 and the copper foil roll 29 when clamping the aluminum foil roll 28 and the copper foil roll 29.

After cleaning, the air inlet pipe 18 drives the cover body 19 through the vacuum pump 17 to suck the cleaned impurities into the collection box 20, and the impurities that are about to enter are filtered under the action of the filter plate 21. At the same time, when the vacuum pump 17 stops working, the impurities fall into the ash storage box 22.
[0039] Among them, the movable plate 5 is moved by extending the driving cylinder 4, and the flap 6 is limited by the limiting rod 9 and the sleeve 10 while the movable plate 5 moves, so that the flap 6 is flipped and drives the four clamps 7 to approach each other, and the aluminum foil roll 28 and the copper foil roll 29 are placed on the periphery of the four clamps 7, and the movable plate 5 is pulled by driving the cylinder 4 to contract, and the four clamps 7 are moved away from each other when the movable plate 5 moves in the opposite direction, and the placed aluminum foil roll 28 and copper foil roll 29 are clamped and fixed, and the aluminum foil roll 28 and the copper foil roll 29 are conveniently replaced by the two clamping assemblies.
