Paper tube just as its name implies is made of paper tube. At the beginning of the mechanical production of paper tubes, they were made by hand, using a stick mold to roll sticky paper into tubes.
After the invention of the paper tube machine, the production of paper tubes became simple and paper tubes size became more and more. Because of low cost, light quality, ease of recovery, no pollution, easy recovery, and other advantages. It is widely used in textile, chemical fiber, printing and dyeing, paper making, agricultural film, fireworks, food packaging, etc.
What are the raw materials for the production of paper tubes?
No matter Kraft paper, white cardboard, coated paper, or other paper, before production it needs corresponding treatment.
First of all, the raw material paper needs to drench the film, then plus a film, that can make it waterproof, oil-proof, can heat, smooth and beautiful.
Secondly, it can be printed by machine if needed.
Thirdly, the coated paper needs to be cut and rewind by the tube cutting and rewinder to make a suitable size. After that, the paper tube is made by gluing, rolling, and cutting on the paper tube machine, finally, dried by the paper tube dryer, and the paper tube is basically formed.
If your products need to be deep processing, then you need to use the paper tube finishing machine to work. For example, the production of tea boxes also needs to roll an edge by the basic shape paper. Can cap machine cover and other processes.
What are the applications of paper tubes?
Such as chemical fiber industrial pipe: DTY pipe, Poy Pipe, FDY pipe, nylon pipe, spandex pipe, spandex covered yarn pipe;
Film Industrial Pipe: Bopp, PET, PVC, Bopa, CPP, agricultural film, fresh-keeping film, winding film, plastic bagpipe (supermarket), an aluminum film, electrical capacitance film, C film.
Tube for printing industry: mainly used in drum printing, film printing, paper printing; Tube for paper industry: tube paper, whiteboard paper, fax paper, Bill paper, pine paper, aluminum paper, writing paper, colored parchment paper, cup paper, Tetra Pak paper, etc.
Packaging tubes: medical equipment, painting, food cans, and another outer packaging; temperature measuring paper tube: steel temperature measuring one-time electric thermocouple; sampler paper tube: fax machine paper tube, battery paper tube, bridge construction tube.
How many processes do they have?
Slitting
Determined to use sand tube paper with even thickness, low moisture content, and smooth surface as the main paper, and to use steeping paper as the surface paper, the paper tape with the required size can be obtained by placing the large sand tube roll and the large surface paper roll in the slitter
Rolling
After the tape on the coil machine into a tube.
Rough Cutting
The high-end paper pipe is placed in the resin-coated paper pipe through the air dryer, rough cut into a certain length of a paper pipe section
Fine Cutting
After cutting, chamfering the end face of the paper tube, coating, disposing and punishing, packaging, the production of a seamless high-grade paper tube is completed
Drying
The rough cut section of the paper pipe into the drying room, until the paper pipe moisture content, is less than 10%.
Gluing
How many layers of the main paper tape and the surface paper tape are disposed of by beveling, and the stacking rules are arranged in parallel to the tape coating machine, a layer of a paper tube is evenly coated on the surface of the main paper tape and the surface paper tape.
Extrusion molding
The dried sections are cooled to room temperature, then each section is put into a preheated mold at 150-280 °C to develop the inner extrusion molding so that the resin-coated on the outside of the paper tube can be fully cured The molding temperature of the mold is 150-280 °C
Beveling detail
The surface paper tape into the beveling machine on both sides of the paper tape for beveling details.
What is the structure of the paper tubes?
The structure of the paper tube is composed of a plurality of surrounding sheets arranged in concentric circles and connected. The paper tube structure is characterized in that at least one paper strip extending in a predetermined spiral direction forms a paper belt around each sheet, the paper tape has the first long side and the second long side arranged relatively, and are connected in a spiral shape, and at least two are dislocated and do not overlap each other in the spiral connection. This structure has strong structural and durability.
What are the methods of making paper tubes?
Pulp pressing
This method solves the problem of multi-layer structure and low strength of paper tubes. The forming process is characterized in that the slurry is injected into the die, the slurry is pressed radially, and a drainage hole is formed by dewatering on the core pipe of the die. The embodiment device of the method comprises a guide rail made of four right-angle steel, a retractable movable blade is arranged at the right angle of each guide rail, and a slide block is arranged between two adjacent guide rails, a core tube with a drain hole is installed at the center of the four guide rails. The pulp is injected between the core tube and the slide block, and the driving device pushes the slide block and the slide block toward the center, extruding the pulp out the drainage hole of the core tube. The method has the advantages of one-step forming and high production efficiency. High strength products, widely used in the textile, chemical fiber production industry.
