Description

Technical Field

[0001] This utility model relates to the field of paper box production technology, specifically to a box blank positioning device for a paper box forming machine. Background Technology

[0002] During the production of cardboard boxes, in order to make the produced cardboard boxes both effective for advertising and aesthetically pleasing, it is necessary to apply a face paper to the box blank. Due to this production need, various types of box-applying devices have appeared on the market.

[0003] Existing carton-attaching devices primarily use belt conveyors to separately transport the face paper and box blanks. Once the face paper reaches a preset position, the conveyor stops, a CCD camera photographs the face paper to confirm its location, and a robot then attaches the positioned box blank to the face paper. In existing devices, the face paper and box blank transport are typically separated and mounted on different racks. Because the face paper sizes vary for different carton specifications, the spacing between the face papers transported on the belt also varies. Due to the limited range of motion of the robot, it needs to be positioned precisely to place the box blank onto the face paper. Therefore, different adjustments to the equipment's installation location are required for producing different carton specifications, significantly impacting the company's production efficiency.
