Description

Technical Field

[0001] This utility model relates to the field of cardboard die-cutting equipment technology, and in particular to a die-cutting device for a corrugated cardboard printing machine. Background Technology

[0002] A corrugated cardboard printing machine is a specialized piece of equipment used for printing on the surface of corrugated cardboard. Through a series of mechanical transmission devices, the corrugated cardboard is transported to the printing unit. In the printing unit, the graphic information on the printing plate (usually a flexographic plate) is transferred to the corrugated cardboard using an ink transfer system. Its working process is similar to that of a general printing machine, but it is optimized for materials like corrugated cardboard, which have a certain thickness and special structure. Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. Operators can typically fold corrugated paper into hollow, box-like structures for storing other items.

[0003] In related technologies, when processing corrugated cardboard, it needs to be die-cut using die-cutting equipment. After the corrugated cardboard enters the die-cutting device via a conveying device, it is first precisely positioned by a positioning system. Then, the transmission system is activated, driving the die-cutting blades to move at a certain speed and trajectory. Simultaneously, a pressure system applies appropriate pressure to the die-cutting blades. When the blades of the die-cutting blades contact the corrugated cardboard, under the action of pressure, the blades cut the cardboard according to the shape on the blades, completing the die-cutting process. Afterward, the die-cut cardboard is sent out of the die-cutting device via a discharge device for subsequent processing or packaging.

[0004] However, there are still shortcomings. When die-cutting corrugated cardboard of different sizes or for different purposes, the position of the die-cutting blades is different. For example, when a wider corrugated box is required, the distance between the die-cutting blades is larger. It is inconvenient to adjust the position of the die-cutting blades in the existing equipment. Utility Model Content

[0045] Working Principle: When die-cutting corrugated cardboard, the operator places the cardboard on the feeding platform 2 and then starts the equipment via the control panel. After startup, the feeding servo motor 6 drives the reciprocating lead screw 7 to rotate. The reciprocating lead screw 7 moves the reciprocating slider 8, which in turn moves two connecting metal blocks 9. These two connecting metal blocks 9 then move their corresponding feeding sliders 5, which in turn move the corrugated cardboard until it comes into contact with multiple conveying rollers 3 and limiting rollers 4. The corrugated cardboard then moves into the die-cutting housing 1 via the multiple conveying rollers 3 and limiting rollers 4. At this time, the die-cutting servo motor 11 starts, driving the die-cutting shaft 10 to rotate. The die-cutting shaft 10 rotates, driving multiple blade wheel bases 13 to rotate. The multiple blade wheel bases 13 rotate, driving the die-cutting blades 14 to rotate, thus die-cutting the corrugated cardboard. When the die-cutting blades need to be adjusted... When adjusting the position of wheel 14, the operator stops the die-cutting servo motor 11 via the control panel. Then, the operator rotates the hexagonal column 21 counterclockwise with a Phillips screwdriver. The rotation of the hexagonal column 21 drives the drive gear 22 to rotate, which in turn drives the driven gear 25 to rotate. The driven gear 25 then drives the flat threaded disc 24 to rotate, and the counterclockwise rotation of the flat threaded disc 24 causes multiple rack sliders 18 to move outward. Multiple limiting grooves 12 are provided on the outer side of the die-cutting shaft 10, and the multiple rack sliders 18 are respectively matched with the corresponding limiting grooves 12. When the multiple rack sliders 18 slide outward, they disengage from the corresponding limiting grooves 12. At this time, the operator can manually adjust the position of the cutter wheel base 13. After adjusting it to the specified position, the hexagonal column 21 is rotated clockwise to reset the multiple rack sliders 18, thus completing the adjustment quickly and easily.

[0046] The technological advancements of this invention compared to existing technologies are: the position of the die-cutting blades 14 can be adjusted conveniently and quickly, and the spacing between the die-cutting blades 14 can be adjusted according to different production requirements, increasing the applicability of the equipment and expanding the production range. At the same time, it eliminates the need for manual pushing and feeding by workers, which is convenient, quick, and reduces labor costs.
