Technical Field

Background

The structure and the function of the existing sorting machine are single. After the existing sorting machine detects products, the existing sorting machine sorts and collects the products in different bin boxes through analysis of detection results. Because the existing bin box mechanism has a large size, the bin box mechanism can only be placed in equipment and is far away from a table board. With the increasing demand of the market for the precision of products, the following disadvantages begin to appear with the existing equipment structure:

1. the bin box is too far from the feed mechanism and the product needs to pass through the air tube and then fall into the bin box after being released at the feed opening. In the falling process of the product, the air pipe and the bin box both damage the product, so that the reject ratio is increased;

2. in the product collecting process, the air pipe gradually deposits dust, so that the product is easy to clamp during blanking;

3. the existing classifier needs to feed materials from different feed openings after detection is finished. Therefore, the blanking mechanism needs to be provided with a plurality of blanking ports, so that the table top of the equipment is compact in position, and the flexibility of the equipment is small;
