Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, and in particular relates to a crease device for carton processing. Background Art

[0002] The packaging box of industrial products must not only ensure the overall compressive strength of the box, but also reduce weight, reduce manufacturing costs, and facilitate transportation. Therefore, people choose packaging cartons made of corrugated cardboard. Most of the existing corrugated cardboard boxes are first die-cut into the unfolded shape of the corrugated cardboard box, and then the corresponding indentation is pressed at the bending position on the corrugated cardboard. People can fold the corrugated cardboard into a corrugated cardboard box through the indentation.

[0003] The Chinese utility model patent with the publication number CN213082495U discloses a crease device for carton production and processing, including a machine body, a bracket fixedly installed on the rear outer wall of the machine body, a motor fixedly installed on the top of the bracket, a slide bar fixedly connected to the rear inner wall of the machine body, the other end of the slide bar is fixedly connected to the front inner wall of the machine body, and a threaded rod is rotatably connected to the rear inner wall of the machine body, and the other end of the threaded rod is rotatably connected to the rear inner wall of the machine body. The utility model uses an air pump, a connecting plate, a connecting column, a plug rod, a card plate and an upper pressing plate in combination. Before cardboard processing, the connecting plate lifting working platform can be adjusted, and different upper pressing plates can be replaced to process the creasing of cardboards of different sizes and types.

[0004] However, the above utility model patent still has some shortcomings:

[0005] During the use of the utility model, the air pump pushes the connecting plate to drive the fixed plate and the connecting column to move downward, and the connecting column drives the upper pressing plate to move downward. The upper pressing plate and the fixed plate squeeze the cardboard to produce an indentation on the cardboard. During the process of squeezing and making the indentation, the dry cardboard is prone to produce fine cracks around the indentation, which affects the appearance of the cardboard and also reduces the pressure-bearing degree of the carton and the load-bearing effect of the support.
