Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a packaging paper box positioning and cutting device. Background Art

[0002] Paper boxes are the most widely used packaging products. According to different materials, there are corrugated paper boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used paper boxes are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers is also different. When producing paper boxes, a cutting device is needed to cut the cardboard.

[0003] The existing patent (publication number: CN212636713U) discloses "a positioning cutting device for packaging paper boxes, which relates to the field of packaging paper boxes. The positioning cutting device for packaging paper boxes includes a frame and a conveyor belt. A small air pump is used to evacuate the inside of the sealing cover so that the cardboard is adsorbed on the movable plate, and the electric push rod is used to push the adjusting blade to cut the cardboard. The cardboard is adsorbed during the cutting process so that the cardboard will not deviate. The bidirectional motor drives the movable plate to rotate counterclockwise so that the movable plate and the adsorbed finished cardboard are close to the collection box. The finished cardboard falls into the collection box by closing the small air pump, and the new cardboard is pushed to the upper surface of the movable plate by the conveyor belt. During the pushing process, the new cardboard can push the waste cardboard remaining from the old cardboard away from the frame, so that the waste cardboard falls into the waste box, which solves the problem that the existing cutting device for packaging paper boxes is prone to deviation when cutting cardboard and cannot collect the finished cardboard and the waste cardboard separately, thereby reducing waste and improving efficiency."
