Abstract

The invention discloses a production processing method of a paperboard, which comprises the following steps: the paper pulp is placed on the extrusion equipment for extrusion forming, repeated extrusion is carried out for multiple times, moisture in the paper pulp is extruded to prepare a paper core for standby application. High-pressure paperboard forming is also helpful for squeezing out more water from paper pulp, but the key is to make a more compact paperboard, improve the compressive strength of the paperboard, have higher ring crush strength and increase the compressive strength of the carton, play an important role when the trays are stacked to more than three heights, meet the requirements of users in various industries and reduce the economic loss caused by package damage in commodity circulation.

Description

Production and processing method of paperboard
Technical Field
The invention belongs to the technical field of paperboard processing, and particularly relates to a production and processing method of a paperboard.
Background
In general, we refer to paper, in a broad sense, as including both paper and board terms. In fact, the number of sheets and boards that differ is only from their basis weight (relative weight per square meter area of sheet). Paper with the weight of 200 g/square meter is generally called paper in folk; paper with the weight of more than 200 grams per square meter is called paperboard, and in the past, the quantitative specification of paper and paperboard in China is as follows: paper is called as below 150 square meters; the paper board is called as the paper board when the square meter is more than 200 g/square meter. Between 150 and 200 grams per square meter is referred to as paperboard (base paper), which is commonly referred to as paper and thick paper as paperboard.
The production and processing method of the paperboard in the prior art is developed rapidly, but still has certain limitations, and the production and processing method of the paperboard in the prior art is complex in process and difficult to ensure the compressive strength and durability of a finished product.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a production and processing method of a paperboard.
In order to achieve the purpose, the invention provides the following technical scheme: a production and processing method of paperboard comprises the following steps:
step one; placing the paper pulp on an extrusion device, carrying out extrusion forming, carrying out repeated extrusion for multiple times, extruding the water in the paper pulp to prepare a paper core for standby,
step two; coating adhesive on two sides of the paper core prepared in the step one, bonding the two sides of the paper core coated with the adhesive to the paper core, then placing the paper core on extrusion equipment to extrude the multilayer paper core to enable the multilayer paper core to be bonded more tightly,
step three; the multilayer paper core is placed on a cutting and line pressing machine to cut and press lines on the paper core board to obtain the required size of the paper board,
step four; placing the paper board on a die cutter, longitudinally pressing lines, transversely cutting and slotting the paper board, then carrying out right-angle cutting on a carton joint,
fifthly, the paper boards are conveyed into a printing machine and printed according to the patterns and the text information required by different manufacturers to manufacture the corresponding paper boards,
and step six, jointing the printed paper boards, and storing the paper boards in a dry environment after the jointing is finished, so that the paper boards are prevented from being damped.
The invention has the technical effects and advantages that: compared with the traditional packaging method, the production and processing method of the paperboard provided by the invention has the advantages that the process is simple, the compression points on the paper fibers are expanded to tightly compress the paperboard, and the more compact the structure of the paperboard is, the higher the strength is. The high-pressure paperboard forming is also beneficial to squeezing out more water from the paper pulp, but the key point is to make a tighter paperboard, improve the compressive strength of the paperboard, have higher ring crush strength and increase the compressive strength of the carton, play an important role when the trays are stacked to more than three heights, meet the requirements of users in various industries, and reduce the economic loss caused by package damage in commodity circulation.

step two; coating adhesive on two sides of the paper core prepared in the step one, bonding the two sides of the paper core coated with the adhesive to the paper core, then placing the paper core on extrusion equipment to extrude the multilayer paper core to enable the multilayer paper core to be bonded more tightly,
step three; the multilayer paper core is placed on a cutting and line pressing machine to cut and press lines on the paper core board to obtain the required size of the paper board,
step four; placing the paper board on a die cutter, longitudinally pressing lines, transversely cutting and slotting the paper board, then carrying out right-angle cutting on a carton joint,
fifthly, the paper boards are conveyed into a printing machine and printed according to the patterns and the text information required by different manufacturers to manufacture the corresponding paper boards,
and step six, jointing the printed paper boards, and storing the paper boards in a dry environment after the jointing is finished, so that the paper boards are prevented from being damped.
In summary, the following steps: compared with the traditional packaging method, the production and processing method of the paperboard provided by the invention has the advantages that the process is simple, the compression points on the paper fibers are expanded to tightly compress the paperboard, and the more compact the structure of the paperboard is, the higher the strength is. The high-pressure paperboard forming is also beneficial to squeezing out more water from the paper pulp, but the key point is to make a tighter paperboard, improve the compressive strength of the paperboard, have higher ring crush strength and increase the compressive strength of the carton, play an important role when the trays are stacked to more than three heights, meet the requirements of users in various industries, and reduce the economic loss caused by package damage in commodity circulation.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
