Description

Technical Field

[0001] This utility model relates to the field of box gluing machine technology, specifically a pre-folding device for a high-speed fully automatic box gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed, die-cut cardboard into its final shape. Machine gluing replaces manual gluing, reducing labor costs and increasing efficiency. A box gluing machine consists of a paper feeding section, a pre-folding section, a bottom-gluing section, a forming section, and a pressing section. Box gluing machines are categorized by function, such as straight-gluing gluing machines and bottom-gluing gluing machines. Most box gluing machines do not have bottom-gluing functionality or even pre-folding; better ones do. Of course, most box gluing machines now have pre-folding. To make bottom-gluing boxes, a bottom-gluing gluing machine is necessary. More advanced gluing machines can also produce hexagonal and irregularly shaped boxes, but these require a glue spraying system and other equipment.

[0003] When a carton gluing machine is in operation, the cardboard needs to be pre-folded. In the existing technology, most carton gluing machines use a fixed plate to limit the cardboard or corrugated cardboard and then fold it directly. Such a strong folding will cause the cardboard or corrugated cardboard to break, thereby affecting the quality and appearance of the carton, reducing the pass rate of carton production, and increasing the production cost of carton. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-folding device for a high-speed fully automatic gluing machine to solve the problem mentioned above, which is that rigid folding will cause damage to cardboard or corrugated cardboard, thereby affecting the quality and appearance of the paper box, reducing the pass rate of paper box production, and increasing the production cost of paper box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-folding device for a high-speed fully automatic box-gluing machine, comprising a worktable, a conveyor trough on the top of the worktable, a conveyor belt on the inner wall of the conveyor trough, a top working box fixedly connected to the side walls at both ends of the worktable, the top working box being located on the top of the worktable, a working cavity being formed at the end of the top working box near the worktable, a plurality of connecting posts evenly arranged on the inner wall of the working cavity, and indentation rollers movably connected to the side walls of the plurality of connecting posts near the conveyor belt, the bottoms of the plurality of indentation rollers being connected to... The top of the conveyor belt is in contact with the inner wall of the conveyor trough, where a pressure bearing plate is installed. The pressure bearing plate is located in the gap of the conveyor belt. The worktable and the top work box provide installation and working space for internal components. The conveyor belt drives the movement of cardboard or corrugated cardboard for paper box production. In conjunction with the creasing rollers, pre-creases are pressed into the cardboard or corrugated cardboard, which facilitates the subsequent pre-folding operation of the cardboard or corrugated cardboard and avoids damage to the cardboard or corrugated cardboard caused by direct folding, thereby improving the pass rate of paper box production.

The movable ends of the multiple cylinders are arranged opposite each other, and the ends of the multiple connecting columns away from the indentation rollers are fixedly connected to the movable ends of the cylinders. The mounting grooves provide mounting space for the cylinders, and the cylinders drive the connecting columns to move, thereby adjusting the position of the indentation rollers and facilitating the adjustment of the pressing position of the pre-crease.

[0007] As a further embodiment of this utility model: a support plate is provided on the side wall of one end of the workbench, and a motor is provided on the top of the support plate. The output end of the motor is movably connected to the workbench and is fixedly connected to the drive roller of the conveyor belt through the workbench, so as to provide power for the movement of the conveyor belt through the motor.

[0008] As a further improvement of this utility model: an air pump is installed on the top of the workbench, and a fixing ring is installed on the outer wall of the air pump. The bottom of the fixing ring, away from both ends, is movably connected to the top of the workbench, and the air pump provides kinetic energy for the movement of the cylinder.

[0009] As a further improvement of this utility model: a controller is installed on the side wall of the top working box near the motor end. The signal output terminal of the controller is electrically connected to the control terminal of the motor and cylinder, and the start and stop of the motor and cylinder are controlled by the controller.

[0010] As a further improvement of this utility model: multiple support columns are evenly arranged at the bottom of the workbench to provide support for the workbench.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the workbench and the top work box provide installation and working space for the internal components. Then, the conveyor belt drives the movement of the cardboard or corrugated cardboard used in the paper box production. The cylinder drives the connecting column to move, thereby adjusting the position of the creasing roller. This facilitates the adjustment of the pressing position of the pre-crease. The creasing roller presses the pre-crease on the cardboard or corrugated cardboard, which facilitates the subsequent pre-folding operation of the cardboard or corrugated cardboard and avoids damage to the cardboard or corrugated cardboard caused by direct folding, thereby improving the pass rate of paper box production.
