Description

A device that can automatically turn 90° during the conveying process of the packing box

technical field

The invention relates to a conveying device for packaging boxes on a production line, in particular to a device capable of automatically turning 90° during the conveying process of packaging boxes.

Background technique

After the product is packed, the side of the box needs to be sprayed or labeled and identified to realize the management and information query of the box and the product. Traditionally, these operations are done manually. With the development of society and the improvement of the degree of automation, in order to improve efficiency and save time and space, it has become urgent to automatically complete these operations on the conveyor line. However, the packaging boxes often move in one direction on the conveyor track. The operating equipment can only operate on the left and right sides of the packaging box, and the front and rear sides cannot be processed. Therefore, the packaging box is automatically turned 90° at a specific position during the conveying process and then moved forward so that the operating equipment on both sides of the conveyor line can handle the packaging. Operate on the specified surface on the box, such as inkjet or labeling and identification, to improve the degree of automation.
