[0002] In large enterprises and institutions, after employees finish their meals, they need to pour the food scraps from their plates into the waste bin, then place the plates on a conveyor belt, and then the plates are sent to large washing equipment for cleaning. In order to improve cleaning efficiency, the plates are often collected in a washing frame first, and then the entire washing frame is sent into the large washing equipment for cleaning.

[0003] Due to the limited space in the canteen, in order to improve the utilization of space, the conveying direction of the washing box and the washing position of the washing box are often on different straight lines. Therefore, a reversing structure needs to be set between the conveying direction of the washing box and the washing position of the washing box so that the washing box can reliably enter the washing position from the conveying position.

[0004] In existing corner-turning devices, transmission structures need to be installed on both the inner and outer sides of the device to achieve product steering. This design presents challenges: firstly, it requires maintaining consistent rotational speeds on both sides of the transmission structure, which demands high precision; secondly, it complicates the overall structure of the corner-turning device and increases its cost.
