Description

Technical Field

[0001] The utility model relates to the technical field of paper box production, in particular to a paperboard die-cutting device. Background Art

[0002] Die-cutting machine, also known as die-cutting machine, cutting machine, CNC punching machine, is a paper packaging and printing post-process mechanical equipment, mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping operations of cardboard, corrugated cardboard, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc.

[0003] Existing cardboard die-cutting machines will generate waste when cutting cardboard, and some large cardboard waste will fall into the cardboard collection area along with the cut cardboard, affecting the collection of the cardboard. In the later stage, it is necessary to manually clean up the unnecessary cardboard waste, which is time-consuming and laborious. At the same time, some cardboard waste with smaller diameters will fall at the cutting place and form accumulation, affecting the die-cutting efficiency.

[0004] Chinese patent CN215282225U discloses a die-cutting machine for cleaning cardboard waste, comprising a processing seat, a rotating shaft is rotatably arranged inside the processing seat, a conveyor belt is rotatably arranged outside the rotating shaft, a waste collection box is fixedly installed at the bottom of the processing seat, draft fans are arranged on both sides of the waste collection box, a ventilation duct is connected between the draft fan and the waste collection box, an end of the ventilation duct away from the draft fan is fixedly connected to a connecting rod, a cross beam is fixedly connected to the middle part of the upper end of the processing seat, a support rod is slidably arranged inside the cross beam, the lower end of the support rod is fixedly connected to the connecting rod, a slide groove is provided in the middle part of the cross beam, and a fixing groove connected to the slide groove is provided on one side of the cross beam, a fixing bolt is slidably arranged inside the fixing groove, and a threaded hole is provided on the side of the support rod close to the fixing groove, and the threaded hole is threadedly connected to the fixing bolt.

[0005] When the device is in use, the cardboard to be cut is placed on the conveyor belt, and the electric telescopic rod is controlled to extend so that the cutting knife cuts the cardboard. When the device needs to adjust the cutting width of the cardboard, the fixing bolt can be loosened and then the spacing of the support rods can be adjusted to adjust the cutting width of the cardboard. It is troublesome to adjust the position of the die-cutting knife by fixing the bolt to adjust the cutting width of the cardboard. During operation, the cardboard is located on the conveyor belt without a fixing device at the bottom. When the die-cutting knife is pressed down for processing, the conveyor belt will be deformed, and the cardboard die-cutting may cause position deviation. At the same time, the device has no limiting device, and the position of each processing is difficult to determine and requires manual operation. The device collects die-cutting waste into a waste collection box. When the waste collection box is full, it still needs to be manually pulled out for cleaning, which is time-consuming and labor-intensive to use and has low work efficiency.

[0006] In summary, a cardboard die-cutting device is now proposed to solve the above technical problems. Utility Model Content

Slide blocks 13 are provided on the front and rear sides of the threaded sleeve 12, and slide grooves are provided on the inner walls of the front and rear sides of the horizontal plate 9. The slide block 13 is slidably connected and arranged in the slide groove, which ensures that the threaded sleeve 12 moves left and right on the threaded rod 10 and also plays a certain limiting role;

[0025] The micro lifting column 1 is installed at the bottom of the threaded sleeve 12, and a mounting plate 15 is arranged below the micro lifting column 1. Die cutters 16 are arranged on the left and right sides of the bottom surface of the mounting plate 15, and a pressure strip 17 is arranged beside the die cutter 16. It also includes a limit cylinder 18. There are two limit cylinders 18, which are respectively installed at the rear ends of the left column 7 and the right column 8. Limit baffles 19 are arranged on the output shafts of the two limit cylinders 18. The extension direction of the output shaft of the limit cylinder 18 is toward the direction of the conveying roller 4. When the conveying roller 4 transports the pallet 6 and is about to arrive at the processing position, the limit cylinder 18 is started, and the output shaft drives the limit baffle 19 to extend. The limit baffle 19 is used to block the pallet 6. At the same time, the feeding motor 5 stops working, and the micro lifting column 1 descends, driving the die cutter 16 and the pressure strip 17 to work.
