Manufacturing method of corrugated paper box with dustproof and waterproof function

Abstract

The invention discloses a manufacturing method of a corrugated paper box with the dustproof and waterproof function. The manufacturing method comprises the following steps of S1, adhesive pasting, wherein side face adhesive strips are pasted to the peripheries of a second box side face and a fourth box side face, and an end face adhesive strip is pasted to the outer end face of a third box side face; S2, inner frame mounting, wherein a square inserting block is aligned to a square inserting groove, at this moment, the square inserting block on the lower power portion of a square reinforcing frame is downward vertically till the square inserting block is inserted into the square inserting groove, and the outer side face of the square reinforcing frame is flushed with the outer end face of the box bottom face; and S3, side folding, wherein the fourth box side face, the third box side face, the second box side face, the second box side face and a first box side face are turned over upwards. Through the designed sealing assembly manner between the faces, the sealing strength of the side faces of the corrugated paper box can be greatly increased, and the dustproof and waterproof performance generated after the corrugated paper box is formed is greatly increased; and during assembling, no u-shaped needles are needed for reinforcing, cost is saved, the sealing action is extremely simple, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of making corrugated paper boxes, and in particular relates to a method for making a dustproof and waterproof corrugated paper box. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single corrugated board and double corrugated board. According to the size of the corrugated board, it is divided into: A, B, C , E, F five types. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Used as packaging for food or digital products, it is relatively environmentally friendly and widely used, and corrugated cardboard can be folded to form c...

Problems solved by technology

[0003] However, when corrugated boxes are assembled, they are generally fixed between the sides and surfaces by staples, which will cause gaps between the surfaces, reduce the dustproof and waterproof effects of corrugated boxes, and the cost is high. When the box surface is folded, it is impossible to grasp that the side is in a vertical state, resulting in uncoordinated assembly of the corrugated box and reducing the quality of use. Therefore, we propose a dust-proof and waterproof corrugated box production method
