Problems solved by technology

[0005] The invention provides a corrugated cardboard and corrugated box production process, one of the purposes is to have the function of increasing the structural strength and solve the problem of poor structural strength of the cardboard. During use, the corrugated cardboard often deforms due to force, resulting in the inner layer of the corrugated cardboard It does not play a protective role, or even damages, thereby affecting the integrity of the package; another purpose is to solve the poor waterproof performance of the cardboard, which will cause the cardboard to be damaged by moisture when the corrugated cardboard touches water, thus Reduce the strength and protective properties of corrugated cardboard to achieve moisture-proof effects

Embodiment 1

[0035] First aspect, such as Figure 1-4 As shown, the present invention provides a corrugated cardboard, comprising a cardboard body 1, an upper paper layer 2 and a bottom layer 3, the top of the cardboard body 1 is fixedly installed with the upper paper layer 2, and the bottom of the cardboard body 1 is fixedly installed with a bottom layer 3 , the inside of the upper paper layer 2 is fixedly equipped with a protective layer 21, the inside of the protective layer 21 is fixedly installed with a protective baffle 211, the bottom of the protective baffle 211 is fixedly installed with a buffer layer 212, and the bottom of the buffer layer 212 is fixedly installed with a buffer pad 213, the inside of the buffer layer 212 is fixedly installed with a pressing block 2121, the inner side of the pressing block 2121 is fixedly installed with a soft spring column 2122, the inside of the pressing block 2121 is fixedly installed with an air cushion layer 2123, and the bottom of the air cus...

Embodiment 2

[0038] Such as Figure 1-4 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the bottom of the protective layer 21 is fixedly installed with a moisture-proof layer 22, and the top of the moisture-proof layer 22 is fixedly installed with a sealing strip 221, and the sealing strip A waterproof coating 222 is fixedly installed on the bottom of the waterproof coating 221, and a waterproof paper layer 223 is fixedly installed on the bottom of the waterproof coating 222.

[0039] In this embodiment, through the tightness and adhesion of the sealant strip 221, the sealant strip 221 is connected to increase the sealability, and then cooperate with the waterproof function of the waterproof coating 222, wherein the waterproof coating 222 adopts polyurethane waterproof coating, polyurethane Waterproof coating is a single-component environment-friendly waterproof coating for liquid construction. It is based on imported polyurethane pr...

Embodiment 3

[0041] Second aspect, such as Figure 1-4 As shown, the present invention also provides a technical solution: a corrugated box production process, the corrugated box production process, including the following steps:

[0042] Step 1. Produce a cardboard body 1, an upper paper layer 2, and a bottom layer 3 of corresponding sizes according to the corrugated box;

[0043] Step 2: Cooperate with the sealing tape 221 to bond and assemble the main body 1 of the cardboard, the upper paper layer 2 and the bottom layer 3;

[0044] Step 3. Use the paper press to properly compress the cardboard, and press at different positions to make folding marks, and then fold to form the shape of the carton;

[0045] Step 4: Glue the folded junctions.

[0046]The first step includes: cutting the cardboard of the raw material with a circular pressure flat cutting device, and after cutting, cooperate with the grinder to polish the cut surface, and the second step includes: using the double-sided adh...

Abstract

The invention discloses a corrugated paperboard and a corrugated carton production process, and relates to the technical field of paperboard production. The corrugated paperboard comprises a paperboard main body, an upper paper layer and a bottom board layer, wherein the upper paper layer is fixedly mounted at the top of the paperboard main body, the bottom board layer is fixedly mounted at the bottom of the paperboard main body, a protective layer is fixedly mounted in the upper paper layer, a damp-proof layer is fixedly mounted at the bottom of the protective layer, and a protective baffle is fixedly mounted in the protective layer. Through mutual cooperation of the protective baffle and the buffer layer, the buffer layer buffers the transmitted acting force to achieve the function of improving the protective performance, then the acting force is conveniently relieved through the rebound resilience of soft elastic columns, and the effect of consuming the acting force is achieved through buffering movement of an air cushion layer and the buffer columns, so that the problem that a paperboard is prone to deformation due to stress in the using process due to the fact that the structural strength of the paperboard is poor is solved, the strength of the corrugated paperboard is improved, and the corrugated paperboard is convenient to use.

Description

technical field [0001] The invention relates to the technical field of cardboard production, in particular to a corrugated cardboard and corrugated box production process. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper. It has good elasticity and extensibility. It is mainly used to make cartons, carton sandwiches and other packaging materials for fragile goods. There are following problems at prior art: [0003] 1. Due to the poor structural strength of the cardboard, corrugated paper often deforms due to stress during use, causing the inner layer of corrugated cardboard to fail to protect and even damaged, thus affecting the integrity of the packaging; [0004] 2. Due to the poor waterproof performance of the cardboard, when the corrugated cardboard touches water, the cardboard will be damaged by moisture, thereby reducing the strength and protective ...
