Abstract

A serrated die cutting tool for processing a corrugated paperboard, comprising a plate-shaped die cutting plate. The die cutting plate is provided with multiple die cutters characterized in that the die cutters comprise serrated blades. The serrated die cutting tool for processing a corrugated paperboard has a simple structure, and can reduce the amount of compression on the corrugated paperboard.

Description

Serrated die cutter for corrugated paper processing

Technical field

The utility model relates to a die cutter, in particular to a sawtooth die cutter for corrugated paper processing.

Background technique

Corrugated paper is a board formed by bonding corrugated paper and corrugated paper formed by corrugating sticks. Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, convenient storage and handling, and is often used to make various packaging boxes. In the process of making the package, there is a common process: die cutting. That is, the corrugated paper is cut according to the shape of the package, and after being cut, the package is formed by appropriate folding, bonding or riveting. At present, the tools for die-cutting corrugated paper are flat knives, that is, the knives are connected in a straight line, and other forms of knives are rarely seen. The flat knife has a large area of contact with the corrugated paper, and during the cutting process, it is easy to form a large pressure on the corrugated paper until the corrugated paper is broken, thereby being cut; in this process, the corrugated paper is squeezed so that it is cut. compression. Compressed corrugated paper, shock absorption, strength will be weakened, resulting in substandard product parameters. How to effectively reduce the height of corrugated paper being compressed is an urgent problem to be solved.

Summary of the invention

In order to overcome the above problems, the present invention provides a sawtooth die cutter for corrugated paper processing with a small amount of corrugated paper.

The technical solution of the present invention is to provide a sawtooth die cutter for corrugated paper processing, which comprises a plate-shaped die-cutting plate, wherein the film cutting plate is provided with a plurality of die-cutting blades, characterized in that the film is cut. The knife includes a serrated blade.

Preferably, the die cutting board is provided with at least one through hole, and each of the circular holes is provided with a telescopic ejector.

Preferably, the die cutter is provided with a bead on at least one side, and the bead has a lower height than the die cutter.

Preferably, the bead is provided on both sides of the die cutter.

Preferably, the spacing between the bead and the die cutter is 3-12 mm.

Preferably, the die cutter comprises an S-shaped curved substrate, and one side of the substrate is provided with the blade.

The sawtooth die cutter for corrugated paper processing of the present invention is provided with a zigzag die cutter on the plate-shaped die cutting plate, so that in the process of die cutting, large pressure is prevented from being formed, and the corrugated paper is compressed. The sawtooth die cutter for corrugated paper processing of the utility model has the advantages of simple structure, small compression amount of corrugated paper and the like.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of the present invention.

As shown in Figures 1 and 2, the present invention provides a serrated die cutter 20 for corrugating paper processing. It comprises a die cutting board 10 which is in the form of a flat plate. A plurality of longitudinal die cutters 20 are provided on the dieboard 10 in accordance with the shape of the cut corrugated cardboard, each film cutter 12 including a serrated blade edge 22. The serrated blade 22 can effectively increase the pressure at the time of cutting, achieve faster cutting, and avoid a large pressure between the blade 22 and the corrugated paper, thereby compressing the corrugated paper.

Further, the die cutting board 10 is provided with a plurality of penetrating circular holes 30, and each of the circular holes 30 is provided with a telescopic ejector (not shown). The ejector pin can be pressed down after the cutting of the die cutting plate 10 after cutting, thereby holding the corrugated paper for separation.

Further, a bead 40 is disposed on both sides of the die cutter 20, and the height of the bead 40 is lower than that of the die cutter 20. When the bead 40 is used for cutting, the corrugated paper is pressed to prevent both sides of the corrugated paper cutting line from being lifted by the pressing of the die cutter 20, which affects the appearance of the corrugated paper after cutting.

Further, when the distance between the test bead 40 and the die cutter 20 is 3-12 mm, the pressing effect is better.

Further, the die cutter 20 includes an S-shaped curved substrate 24, and one side of the substrate 24 is provided with a blade twenty two. The S-shaped structure helps to increase the strength of the substrate 24.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention. And deformation should also be regarded as the scope of protection of the present invention.
