Description

Technical Field

[0001] The present invention relates to the technical field of paper box folding and forming, in particular to an automated production device and method for paper box folding and forming. Background Art

[0002] With the increasing use of product packaging, merchants have a great increase in demand for packaging cartons. The existing carton processing and forming devices require manual work to discharge the carton after the carton is folded and formed, which is not conducive to improving the intelligent production of carton processing, and has low production costs and production efficiency. Therefore, improving carton productivity, reducing physical labor and reducing production costs through automation is an important way to adapt to modern production.

[0003] In the prior art, a paper box processing and forming device with announcement number CN218577094U includes a base, a paper box forming press body and a forming seat, wherein the forming press is installed on the base, and the forming seat is installed on the base. The device also includes a loading assembly, which includes a bottom plate, a mounting frame, a telescopic suction cup and a sliding member. The bottom plate is fixedly connected to the base and is located on a side of the base close to the forming seat. The mounting frame is fixedly connected to the base and is located on a side of the base close to the bottom plate. The telescopic suction cup is connected to the mounting frame through a sliding member and is located on the top of the mounting frame. The sliding member is connected to the telescopic suction cup and drives the telescopic suction cup to move horizontally, thereby obtaining automatic loading operation of the paper box processing and forming device, reducing personal safety hazards, and speeding up the loading rate.

[0004] The above-mentioned carton processing and forming device extends toward the carton blank through the telescopic suction cup, absorbs the carton ingredients and moves them upward, and then drives the telescopic suction cup through the sliding component to move the carton blank to the upper end of the forming seat, and the pressure plate of the carton forming press body presses downward to form, thereby realizing the automatic loading operation of the carton processing and forming device, reducing personal safety hazards and speeding up the loading rate. In the existing technical solutions, the device can only fold cartons of fixed sizes, which has great limitations. Moreover, when loading the carton, it is used at the back, and the telescopic suction cup needs to extend downward to suck up the carton, which is not convenient for saving time and improving the efficiency of folding boxes.

[0005] In summary, to this end, we provide an automated production equipment and method for folding and forming paper boxes. Summary of the Invention
