The first conveying mechanism 2 and the second conveying mechanism 3 are arranged in an upper and lower interval on the cleaning box 1. The guide mechanism 4 is arranged near the end of the first conveying mechanism 2 on the cleaning box 1. The cleaning mechanism 5 is arranged above the first conveying mechanism 2 and the second conveying mechanism 3 on the cleaning box 1. The guide mechanism 4 is used to guide the packaging bag on the first conveying mechanism 2 to flip and fall on the second conveying mechanism 3. The second conveying mechanism 3 is located downstream of the first conveying mechanism 2. In the height direction of the cleaning box 1, the projections of the first conveying mechanism 2 and the second conveying mechanism 3 at least partially overlap.

[0046] At this time, as arranged above, after the packaging bag falls on the first conveying mechanism 2, it will travel with the first conveying mechanism 2. In the process of the packaging bag traveling, the first side of the packaging bag faces upward, and the cleaning mechanism 5 will clean the first side of the packaging bag. When the packaging bag moves to the end of the first conveying mechanism 2, it will be flipped from the first conveying mechanism 2 to the second conveying mechanism 3 by the guide mechanism 4. At this time, the second side of the packaging bag faces upward, and the second side of the packaging bag is cleaned by the cleaning mechanism 5, ensuring that both sides of the packaging bag can be thoroughly cleaned and improving the cleaning effect.

[0047] Moreover, in the process of cleaning the packaging bag, no manual intervention is required. From the feeding of the packaging bag, the cleaning to the discharging, all are automatically completed by the equipment, greatly reducing the time and labor intensity of manual operation, reducing the labor cost, improving the production efficiency, and adapting to large-scale cleaning.
