Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically to an indentation device for packaging cardboard box production. Background Technology

[0002] Packaging cartons are used to package various items. They are made of paper products, are low in cost, and are easy to seal. They are often used for transporting goods and organizing materials. During the production process, a creasing machine is used to cut the cardboard. A creasing machine is a machine used to cut various sheet materials and is widely used in printing, packaging and other industries.

[0003] A search revealed that CN213082496U discloses a creasing device for packaging carton production, including a base, a top plate above the base, a support rod between the base and the top plate, a creasing component in the middle of the top plate, a creasing plate below the creasing component, and a fixing component between the creasing plate and the creasing component. This utility model features a fixing component. Pulling outwards on a sliding rod retracts the locking block, inserting the upper end of the creasing plate into the fixing seat. Releasing the sliding rod causes it to move back under the elastic force of a spring, moving the locking block into the slot. This allows for easy disassembly and replacement of the creasing plate. Pulling upwards on a sliding rod activates an electric push rod, moving the moving block above the cardboard. Releasing the sliding rod causes it to move back under the action of a spring, pressing the fixing plate against the cardboard, thus quickly and firmly fixing the cardboard.

[0004] However, in actual use, after each cardboard crease is completed, the creased cardboard needs to be manually removed from the base surface. This is not only time-consuming and labor-intensive, but also affects the overall production efficiency, so it needs to be improved. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a creasing device for packaging carton production, which has the following beneficial effects:

[0015] 1. This creasing device for packaging carton production can limit the cardboard by setting a limiting baffle, thus facilitating the alignment of the cardboard with the creasing template. The square plate is driven to move down by a hydraulic cylinder, so that the creasing template can be pressed tightly against the creasing table, thereby performing the creasing operation on the cardboard placed on the surface of the creasing table. During the creasing operation, the conveyor wheel will retract into the groove, so as not to affect the creasing of the cardboard. After the creasing is completed, the U-shaped wheel frame will pop up, and the motor drives the conveyor wheel to rotate, which can automatically transport the creasing cardboard to the left side of the base plate, thus completing the automatic unloading. The operation process saves time and effort and effectively improves production efficiency.

[0016] 2. This creasing device for packaging carton production, by setting up a belt conveyor mechanism, side support plates, adjusting screws, guide plates, and a second limit slide bar, allows the guide plate to be adjusted by turning the adjusting screw in conjunction with the second limit slide bar. The belt conveyor mechanism transports the cardboard, and the guide plate guides both sides of the cardboard, thus realizing automatic feeding of the cardboard onto the creasing table surface, further improving production efficiency and saving manpower.

Four grooves 8 are formed on the upper surface of the creasing table 2, and the four grooves 8 correspond vertically to the four corners of the creasing template 7. A U-shaped wheel frame 9 is slidably connected to the inner wall of the groove 8, and the U-shaped wheel frame 9 is elastically connected to the bottom of the groove 8. A motor 10 is fixedly connected to the inner side of the U-shaped wheel frame 9. The inner side of the U-shaped wheel frame 9 is also rotatably connected to the conveyor wheel 11, and the output end of the motor 10 is connected to the conveyor wheel 11 for transmission. By setting the limit baffle 4, the cardboard can be limited, so that the cardboard can be aligned with the creasing template 7. The square plate 6 is moved down by the hydraulic cylinder 5, so that the creasing template 7 can be pressed tightly against the creasing table 2, so that the cardboard placed on the surface of the creasing table 2 can be creasing. During the creasing operation, the conveyor wheel 11 will retract into the groove 8, so as not to affect the creasing of the cardboard. After the creasing is completed, the U-shaped wheel frame 9 will spring up, and the motor 10 drives the conveyor wheel 11 to rotate, which can automatically transport the creasing cardboard to the left side of the base plate 1, thus completing the automatic unloading. The operation process saves time and effort and effectively improves production efficiency.
