Description

Technical Field

[0001] The invention relates to the technical field of paper box packaging, in particular to a paper box opening mechanism. Background Art

[0002] In the modern packaging industry, paper boxes are one of the main forms of commodity packaging. They are widely used and in huge demand. In order to improve storage and transportation efficiency, paper boxes are usually stacked in a flat state. When the commodity packaging is used, the folded paper boxes are unfolded into a three-dimensional state to accommodate the product, which is the so-called "opening the box".

[0003] At present, most of the mainstream box opening mechanisms on the market use suction cup groups as carton grabbing and moving tools. The suction cup group is driven by a driving structure (usually composed of guide rails, screw rods, motors and other components, and is widely used in CNC machine tools, handling machinery and other fields to move objects in space in the X, Y and Z directions) to move to the plane position of the folding carton, and the suction cup group adsorbs one side of the carton. Then, under the action of the control system, the carton is driven to move along the set trajectory. During the movement of the carton, one side of the carton will come into contact and abut against the set box opening auxiliary part (usually a plate), and the carton is transformed from a plane state to a three-dimensional state through continuous squeezing force to complete the box opening. During the squeezing box opening process, the side of the folding carton that is in contact with the box opening auxiliary part often produces scratches due to friction and squeezing. These scratches not only affect the appearance of the carton and reduce the overall beauty of the product, but may also have an adverse effect on the sealing and protective performance of the carton. Especially in industries with high requirements for packaging appearance, the scratch problem is particularly prominent.

[0004] Therefore, the present invention proposes a carton opening mechanism to solve the above problems. Summary of the invention

As the belt conveyor 601 runs, the corresponding clamping boss 602 at the rear end of the transmission path will contact with the side of the paper box close to the second suction cup 504, thereby clamping the paper box to achieve position limiting and keep it in a vertical state for transportation and transfer.
