When the surface of the packaging bag is cleaned and moved to the bottom of the spraying part 21, the spraying part 21 can spray the packaging bag; when the brush 33 located at the bottom is contaminated with more dust particles due to long-term use, the No. 2 motor 35 can be started to make the two discs 31 rotate, and the rotating rod 32 located at the top and the rotating rod 32 located at the bottom are swapped, and the used brush 33 is located at the top; then the rotating rod 32 located at the bottom can be rotated, so that the brush 33 located at the bottom continues to clean the surface of the packaging bag, and at the same time, the No. 1 automatic telescopic rod 71 is started to move the carrying plate 7 toward the connecting frame 3, so that the carrying plate 7 is inserted into the two rotating discs. After that, the brush 33 is moved between the upper and lower parts; the No. 1 motor 34 is started to make the rotating rod 32 at the upper part drive the brush 33 at the upper part to rotate, and then the electric telescopic rod 5 is started to make the No. 1 screw rod 41 drive the cleaning plate 43 to move downward through the movable plate 42. When the cleaning plate 43 contacts the brush 33 at the upper part, the No. 3 motor 44 is started to make the No. 1 screw rod 41 rotate, so that the movable plate 42 drives the cleaning plate 43 to move back and forth, and cooperate with the rotation of the brush 33 to clean the dust particles on the brush 33, so that the dust particles fall on the supporting plate 7 and are collected; when the brush 33 at the upper part is cleaned, the supporting plate 7 and the cleaning plate 43 can be restored. After the two brushes 33 are used alternately, the dust particles can be cleaned alternately according to the above operation; the main bodies of the two No. 1 motors 34 are respectively fixed on a disc 31, and the rotating shafts of the two No. 1 motors 34 pass through the disc 31 and are respectively fixed to one end of the two rotating rods 32.
