Embodiment 1

[0023] Embodiment 1: Get 500 kilograms of waste paper pulp extracted with environmental protection technology in the production of paper mills, pulverize it evenly for future use with a pulverizer, get 50 kilograms of stone powder for future use, get 45 kilograms of water to boil, get 5 kilograms of polyvinyl alcohol, and stir Put the waste paper pulp, stone powder and glue into the mixer to mix evenly, send the mixed waste paper pulp into the hopper of the extruder through the conveyor, open the extruder to extrude the waste paper pulp Extruder die mouth output, turn on the cutting knife motor, the paper tube will be cut off automatically with the cutting knife after reaching the required length, the conveyor will automatically send the cut paper tube into the high-temperature drying tunnel, and the paper tube will be dried through the high-temperature drying tunnel Send it out after drying, and it will become a qualified paper tube.

Embodiment 2

[0024] Embodiment 2: Take 500 kilograms of waste cardboard, put it into a beater and beat it into pulp for later use, take 50 kilograms of stone powder for later use, take 45 kilograms of water and boil it, take 5 kilograms of polyvinyl alcohol, put it in while stirring, and make glue, put Put the waste paper pulp, stone powder and glue into the mixer and stir evenly, send the mixed waste paper pulp into the hopper of the extruder through the conveyor, open the extruder to extrude the waste paper pulp and output it from the die mouth of the extruder, and open the cutting knife Motor, after the paper tube reaches the required length, it is automatically cut off with a cutting knife, and the conveyor automatically sends the cut paper tube into the high-temperature drying tunnel, and the paper tube is sent out after being dried in the high-temperature drying tunnel, and it becomes a qualified paper tube .

Embodiment 3

[0025] Embodiment 3: Get 250 kilograms of waste paper pulp obtained with an environmentally friendly method in the production of a paper mill, pulverize it evenly for future use with a pulverizer, get 250 kilograms of waste cardboard, beat it into pulp with a beater for future use, get 50 kilograms of stone powder for future use, and get 45 kilograms of water Boil, take 5 kg of polyvinyl alcohol, put it into the glue while stirring, put the pulp, stone powder, and glue into the mixer and stir evenly, send the mixed waste paper pulp into the hopper of the extruder through the conveyor, and start the extrusion After the waste paper pulp is extruded by the extruder, it is output from the die mouth of the extruder, and the cutting knife motor is turned on. After the paper tube reaches the required length, it is automatically cut off by the cutting knife, and the conveyor automatically sends the cut paper tube into the high-temperature oven. Road, the paper tube is sent out after be...

Abstract

The invention relates to a method for producing paper tubes by waste paper pulp. The method is characterized in that the waste paper pulp used as a raw material is blended with glue and stone powder to produce the paper tubes by a squeezing method. Paper pulp is manufactured by steps including 1, uniformly grinding the waste paper pulp disposed during production of a paper mill by a grinder; 2, beating waste paperboards by a beater to obtain paper pulp; and 3, mixing the waste paper pulp and the paper pulp manufactured from the waste paperboards into mixed waste paper pulp. The glue is manufactured by steps including 1, boiling water and adding polyvinyl alcohol into the water to prepare glue; and 2, adding borax and caustic soda flakes into corn starch to prepare glue. The paper tubes made of the waste paper pulp have the advantages of low production cost, fast speed, good quality, simplicity in operation, wide production range and high applicability, and have an excellent commercial prospect, and the method is an ideal paper tube production method at present.

Description

technical field [0001] The invention relates to a method for producing paper tubes, in particular to a method for producing paper tubes with waste paper pulp. Background technique [0002] At present, the production of paper tubes in my country uses bobbin paper or kraft cardboard as raw materials, and is produced by two methods: spiral winding or parallel winding. The production of paper tubes by spiral winding is fast and of good quality, and is widely used. The production of paper tubes by the spiral method has higher requirements on the quality of paper and glue, higher costs, and higher requirements on the workers' operating skills. It is easy to produce defective products in the initial production, and the yield is low; the production of paper tubes by the parallel winding method If it is produced by machinery, there are also the problems of high requirements for paper and glue and high cost; if it is produced by hand, although the requirements for paper and glue are not...
