[0025] like Figure 1 The illustrated foil brushing and dust collection device includes a motor 1, a dust collection hood 2, and a brush roller 3. The brush roller 3 is disposed inside the dust collection hood 2 and is connected to the motor 1. One side of the dust collection hood 2 is provided with an arc-shaped dust collection arc surface 21. A brush through hole 22 is provided in the middle of the dust collection arc surface 21, and the brush roller 3 protrudes from the brush through hole 22. Negative pressure suction ports 23 are provided on both sides of the brush through hole 22, and the negative pressure suction ports 23 are arranged side by side with the brush through hole 22. One end of the dust collection hood 2 is provided with a negative pressure connection port 4, which is connected to a negative pressure pipe.

[0026] like Figure 2 As shown, in this embodiment, the foil brushing and dust collection device is located on one side of the foil turning roller 5, with the dust collection arc facing the foil turning roller 5 and the curvature of the dust collection arc facing the foil turning roller 5 being the same. The brush roller 3, protruding from the brush through-hole 22 within the dust collection arc, brushes the foil 11 on the foil turning roller 5. The foil 11 is wound around the foil turning roller 5, with the dust collection arc 21 facing the foil turning roller 5, and the brush roller 3 brushes the foil 11 on the foil turning roller 5. The lint rolled up by the brush roller 3 is sucked away through the negative pressure dust collection port 23, thus completing the lint removal of the foil.

[0027] like Figure 1 and Figure 3As shown, one end of the dust collection hood 2 is provided with a brush support 6, and the other end is provided with a quick-release brush mechanism 7. The brush roller 3 is mounted on a rotating shaft 8. One end of the rotating shaft 8 extends out of the dust collection hood 2, is mounted on the brush support 6, and is connected to the motor 1. The other end of the rotating shaft 8 is connected to the quick-release brush mechanism 7 via a first bearing 74. The end of the dust collection hood 2 connected to the quick-release mechanism is provided with a brush loading and unloading hole. The brush support 6 is connected to the rotating shaft 8 via the first bearing 74, and the rotating shaft 8 extends into the insertion slot of the motor 1 connecting shaft. The shape of the end of the rotating shaft 8 connected to the motor 1 connecting shaft matches the shape of the insertion slot. In this embodiment, the rotating shaft 8 can be pulled out from the first bearing 74 on the brush support 6.

[0028] like Figure 4 and Figure 5 As shown, the quick-release brush mechanism 7 includes a quick-release bracket 71 and a limiting screw 72. The upper part of the quick-release bracket 71 is connected to the second bearing 9 by screws. A transverse limiting groove 73 is provided on one side of the middle part of the quick-release bracket 71. The limiting screw 72 passes through the transverse limiting groove 73 and is connected to the dust cover 2. The bottom of the quick-release bracket 71 is connected to the dust cover 2 by fixing bolts. In this embodiment, in order to facilitate the installation and removal of the brush roller 3, a bakelite handle ball 75 is provided at one end of the rotating shaft 8. The brush roller 3 needs to be replaced every once in a while. When it needs to be replaced, the fixing bolt is removed from the quick-release bracket 71, and then the limiting screw 72 is loosened. At this time, the quick-release bracket 71 can rotate clockwise in the transverse limiting groove 73. At this time, the bakelite handle ball 75 is grasped, and the brush roller 3 and the rotating shaft 8 can be pulled out from the dust cover 2, thereby replacing the brush roller 3.

The baffle plate 10 enables the negative pressure suction port 23 on the dust hood 2 to generate as much air force as possible due to the negative pressure, thereby sucking away as much of the hair and debris rolled up by the brush roller 3 as possible.

[0030] In this embodiment, the brush roller 3 brushes the electrode foil to remove dust. The lint rolled up by the brush roller 3 is sucked away through the negative pressure dust suction port 23, thus completing the cleaning of the electrode foil. Meanwhile, the quick-release brush mechanism 7 in this invention enables the brush roller 3 to be quickly disassembled.

[0031] The foil brushing and dust collection device of this embodiment is used for dust removal of the foil of aluminum electrolytic capacitors; it can also be used for dust removal of the foil of lithium-ion batteries.
