Cutting device for processing packaging paperboard and cutting method thereof

Abstract

The invention provides a cutting device for processing a packaging paperboard and a cutting method of the cutting device. The cutting device comprises an outer cover shell and a cutting device, the feeding mechanism adsorbs the packaging paperboards fed into the outer cover shell through negative pressure and places the adsorbed packaging paperboards on the positioning mechanism; the positioning mechanism comprises a pre-positioning mechanism and a secondary positioning mechanism, the pre-positioning mechanism clamps the packaging paperboard on the pre-positioning mechanism at a set position, and the secondary positioning mechanism adsorbs the packaging paperboard at the set position through negative pressure; a cutting mechanism; and the negative pressure generating mechanism generates suction force near the positioning mechanism through gas exhausted by the secondary positioning mechanism and the feeding mechanism, and dust and paper scraps on the positioning mechanism are removed through the suction force. And paper scraps can be removed in time.

Description

technical field [0001] The invention relates to the technical field of packaging cardboard production, in particular to a cutting device and a cutting method for processing packaging cardboard. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is a combination of multi-layer materials, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row and support each other to form a triangular structure support body. Therefore, it has high mechanical strength and can withstand collisions and falls during transportation. It is often used in Manufactures packaging cartons, fillings for cartons, and packaging materials for fragile goods. [0003] In the production process of corrugated cardboard, after the finished continuous corrugated paper roll is cut longitudinally, it usually needs to be cut int...

AI Technical Summary

Problems solved by technology

Rectangular cardboard with excessive size deviation will cause problems such as carton printing displacement, die-cutting displacement, inaccurate box size, and impact on the compressive strength of corrugated boxes.

[0005] In addition, when corrugated cardboard is processed, a lot of waste and dust are often generated. Since there is no good waste recycling device in the general cross-cutting machine, there are more waste and dust inside the cross-cutting machine, which will affect It may even cause adverse consequences such as machine damage and corrugated cardboard damage. In addition, most of the existing cross-cutting machine dust removal devices need to be manually operated, which is not only inefficient, but also the operating environment for workers is harsh. , seriously affecting the health of workers
