Problems solved by technology

This paper tube process only solves the problem of seams on the surface of ordinary paper tubes, but because the production method is to grind the spiral pattern on the surface of the basically formed paper tube, the paper tube still has surface Defects such as not smooth

Embodiment 1

[0033] The production method of the present invention mainly includes several processes such as raw material paper cutting, groove treatment, paper tape gluing, tube rolling, surface coating, rough cutting, paper tube drying, extrusion molding, and fine cutting. After the process, a layer of resin is coated on the outer surface of the wound paper tube. After the paper tube is roughly cut and dried, it is put into the inner extrusion molding machine one by one for extrusion molding. Because a layer of resin is coated on the outer surface of the paper tube Resin, under the action of internal extrusion molding, the resin is first melted into a film and then cooled, so that a seamless, smooth and clean resin layer is formed on the outer surface of the paper tube. The paper tube prepared by the method also has the characteristics of high straightness, high roundness, high surface hardness, etc., and overcomes all the defects existing in the original ordinary paper tube.

Abstract

The invention relates to a method for producing a high-grade paper tube with seamless surface for the coiling of thin materials. The invention aims to provide a method for producing a high-grade paper tube with seamless surface, and the paper tube produced by the method has the characteristics of smooth surface, high cleanliness, high humidity resistance, good straightness, high roundness, high surface hardness and the like. The technical proposal of the invention comprises that: the method for producing the high-grade paper tube with seamless surface comprises the steps of: 1) the cutting of raw material paper; 2) groove treatment; 3) the sizing of a paper tape; 4) tube coiling; 5) surface coating; 6) rough cutting; 7) the drying of the paper tube; 8) extrusion forming; and 9) fine cutting.

Description

technical field [0001] The invention relates to a method for making a surface-seamless high-grade paper tube for thin material coiling. Background technique [0002] With the rapid economic growth, the packaging materials industry, electronic information industry, metal foil board manufacturing industry, paper industry, etc. Glass fiber cloth, aluminum foil, copper foil and other industries have increased demand for paper tube products. [0003] At present, the processing methods of domestic paper tubes are spiral tubes and flat roll tubes. The paper tubes made by these two methods have seams on the surface, are not smooth enough, have low straightness, low geometric precision, and insufficient cleanliness. and other defects, it is difficult to meet the coiling requirements of thin or ultra-thin materials. Therefore, the technology involved in the present invention is aimed at the specific needs of users. The selection of surface paper, surface coating materials, processin...
