The affixed label is more stable and can keep the placement box in the middle of the conveyor belt, while ensuring that the placement box will not shake.

[0016] 5. The present invention provides a belt cleaning device. The scraper can scrape off the stains on the surface of the conveyor belt that are difficult to remove. The sponge plate and the bristles can clean the dust on the surface of the conveyor belt. At the same time, since the conveyor belt will shake and tilt, the rotation adjustment of the rotating block and the sixth spring can better clean the dirt on the conveyor belt to ensure the comprehensiveness of the cleaning. The cleaning roller rotates under the drive of the conveyor belt to clean the dirt remaining on the scraper, further improving the cleaning ability of the conveyor belt and ensuring the cleanliness of the products on the transmission belt.
