Cutting device for tooth-shaped packaging paper

Abstract

The invention relates to a cutting device for tooth-shaped packaging paper. The cutting device comprises a rectangular frame, wherein a vertical strip-shaped hole is formed in the left side face and the right side face of the rectangular frame respectively, a first rotary shaft is installed in the two strip-shaped holes, a second rotary shaft is movably installed at the lower portion of the rectangular frame and is parallel to the first rotary shaft, and the first rotary shaft and the second rotary shaft can rotate with respect to the rectangular frame. Two ends of the first rotary shaft penetrate through the left side face and the right side face of the rectangular frame respectively to be movably provided with a bolt respectively, and the other end of each bolt penetrates through a fixing block arranged on the corresponding side of the rectangular frame and is connected with a rotary handle. The cutting device adopts a toothed disc replacing a round blade to cut the tooth-shaped paper, can smoothly cut the tooth-shaped paper and can smoothly cut soft tooth-shaped paper with a sparse tooth-shaped structure, and cutting trails are smooth. Compared with a blade cutting mode, cutting mark tearing caused by the mode that soft-textured or thinner tooth-shaped paper is cut by adopting the blade is avoided.

Description

technical field [0001] The invention relates to the technical field of toothed paper processing equipment, in particular to a toothed paper cutting device for packaging. Background technique [0002] The filling inside the carton is usually filled with origami paper. The shape of the origami paper is similar to that of a tooth, so it is also called tooth-shaped paper. The tooth-shaped paper needs to be glued after forming so that it can be glued together. In order to prevent the toothed paper from opening and returning to its original shape at will, a piece of smooth paper is pressed on one side of the toothed paper, and the toothed structure of the toothed paper is fixed by the smooth paper. [0003] In the subsequent processing, it is necessary to cut the toothed paper into strips, and then glue the strips of toothed paper together to form a block. Block-shaped serrated paper provides support strength and is the final material for filling. However, tooth-shaped paper is ...

Problems solved by technology

However, tooth-shaped paper is not easy to cut. The existing cutting method usually uses a cutting knife to cut. However, direct cutting with a single knife is easy to crush the tooth-shaped paper and destroy the supporting structure of the tooth-shaped paper. Some manufacturers use double-knife cutting to cut the tooth-shaped paper. Paper, that is, use two circular blades to stagger each other, and cut the toothed paper passing between the two circular blades. This method can reduce the degree of crushing of the toothed paper to a certain extent, but with the tooth shape The paper material becomes softer, the thickness of the toothed paper decreases, and the density of the tooth structure decreases. This cutting method is still very easy to crush the toothed paper, and if the circular blade is not guaranteed to be sharp enough, the toothed paper will often be torn , so that the circular blade has high maintenance requirements and low adaptability, which cannot meet the cutting requirements for the improved toothed paper structure when saving energy and reducing emissions.
