Packaging material and manufacturing method thereof

Abstract

The invention relates to the technical field of packaging material manufacturing, in particular to a packaging material and a manufacturing method of the packaging material, and a glue removing deviceused in the method comprises a rectangular pool, screw rods, a grinding plate and first motors; two screw rods are rotatably connected to the two side walls of the rectangular pool, and two first motors are mounted on the outer side wall of the rectangular pool; an output shaft of each first motor is connected with one end of the corresponding screw. Threads at the two ends of the screw rod are arranged oppositely, and the two ends of the screw rods are in threaded connection with sliding blocks; a rack is fixedly connected between the two corresponding sliding blocks; a sliding plate is arranged at the lower end of the rack; according to the packaging material and the glue removing device used in the manufacturing method of the packaging material, the first motor drives the grinding plate to move up and down, and the second motor drives the grinding plate to slide along the rack in a matched mode; therefore, glue on the corrugated board is completely removed by the grinding board, the purity of the packaging material raw material is improved, and the quality of the packaging material is further improved.

Description

technical field [0001] The invention relates to the technical field of packaging material production, in particular to a packaging material and a production method of the packaging material. Background technique [0002] Packaging materials include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials and other main packaging materials, as well as auxiliary materials such as strapping, decoration and printing materials; With the development and the improvement of people's living quality, the amount of packaging materials is also significantly increased; affected by national policies and the environment, the raw materials of existing packaging materials are mainly recycled and processed from waste packaging materials, and glue is stuck on the waste packaging materials , The glue needs to be taken out before it can be used. The existing chemical degumming method affects the mechanical properties of the raw material...

Problems solved by technology

[0002] Packaging materials include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials and other main packaging materials, as well as auxiliary materials such as strapping, decoration and printing materials; With the development and the improvement of people's living quality, the amount of packaging materials is also significantly increased; affected by national policies and the environment, the raw materials of existing packaging materials are mainly recycled and processed from waste packaging materials, and glue is stuck on the waste packaging materials , the glue needs to be taken out before it can be used. The existing chemical degumming method affects the mechanical properties of the raw material. The existing physical degumming method is water washing, but the glue on the raw material cannot be completely removed after hydrolysis, thus affecting the quality of the packaging material.

[0003] There are also some technical solutions about packaging materials and packaging materials production methods in the prior art. For example, a patent with application number PCT / CN2016 / 077288 discloses a lightweight and environmentally friendly biomass packaging material and its preparation method , the technical scheme uses biomass fiber material as the base material, soybean protein as the adhesive, and adds a small amount of environmentally friendly additives. After paving, molding, hot pressing, and demoulding in the mold, it is made into a packaging material with certain mechanical strength. ; This technical scheme has the advantages of light weight and no pollution; but this technical scheme still cannot solve the problem that the glue contained in the raw material cannot be removed, which causes the limitation of this scheme
