Problems solved by technology

[0003] 1. There are potential safety hazards, and operators need to be trained in strict operating specifications, and operators must also wear cut-resistant gloves
[0004] 2. Because the manual operation is used, when the paper roll is relatively large and there are many damaged papers, using the cutter for a long time will make people feel tired, prone to cuts and reduced efficiency
[0005] 3. The use of knives will cause cuts to the reel shaft and paper core tube, reducing their service life

Embodiment 1

[0022] A method of using high-pressure water to treat paper rolls, using a high-pressure cleaning machine to cut paper rolls, aiming the nozzle of the high-pressure cleaning machine at the paper rolls to be cut, using high-pressure water to directly cut the paper rolls, using tap water, and high-pressure cleaning The water outlet pressure of the machine is 150bar, the nozzle used is a 0° linear nozzle, the water outlet direction of the nozzle is always perpendicular to the cut surface of the paper roll, the distance between the nozzle and the paper roll is 20mm, and the moving speed of the control nozzle is 0.1m / s, complete the cutting of the paper roll.

Embodiment 2

[0024] A method of using high-pressure water to treat paper rolls, using a high-pressure cleaning machine to cut paper rolls, aiming the nozzle of the high-pressure cleaning machine at the paper rolls to be cut, using high-pressure water to directly cut the paper rolls, using tap water, and high-pressure cleaning The water outlet pressure of the machine is 180bar, the nozzle used is a 0° linear nozzle, the water outlet direction of the nozzle is always perpendicular to the cut surface of the paper roll, the distance between the nozzle and the paper roll is 25mm, and the moving speed of the control nozzle is 0.2m / s, complete the cutting of the paper roll.

Embodiment 3

[0026] A method of using high-pressure water to treat paper rolls, using a high-pressure cleaning machine to cut paper rolls, aiming the nozzle of the high-pressure cleaning machine at the paper rolls to be cut, using high-pressure water to directly cut the paper rolls, using tap water, and high-pressure cleaning The water outlet pressure of the machine is 200bar, the nozzle used is a 0° linear nozzle, the water outlet direction of the nozzle is always perpendicular to the cut surface of the paper roll, the distance between the nozzle and the paper roll is 30mm, and the moving speed of the control nozzle is 0.3m / s, complete the cutting of the paper roll.

[0027] The invention uses a high-pressure cleaning machine to cut off broken paper, replacing traditional knives. Because paper in papermaking is stored in rolls, some paper needs to be returned to the furnace after being reduced to unqualified products, that is, it will be returned to the slurry system, because the paper r...

Abstract

The invention relates to a method for treating a paper roll through high-pressure water. A high-pressure cleaning machine is used for cutting the paper roll. A nozzle of the high-pressure cleaning machine is aligned with the paper roll to be cut. High-pressure water is used for directly cutting the paper roll, the water discharging direction of the high-pressure water is perpendicular to the cut face of the paper roll all the time, the moving speed of the nozzle is controlled to range from 0.1 m/s to 0.3 m, and cutting of the paper roll is completed. Compared with the prior art, the method cannot cause permanent damage to a paper rolling shaft, and the cutting efficiency is further improved.

Description

technical field [0001] The invention relates to a method for treating paper rolls, in particular to a method for treating paper rolls with high-pressure water. Background technique [0002] The base paper in the papermaking process is run in the form of coils, so the base paper is in roll form. In the actual production process, there may be some recycled base papers caused by quality problems or abnormal production. These recycled base papers exist in the form of "rolls". Once the tube is taken out, the paper roll must be cut to perform secondary shredding. The traditional paper cutting method is to use a knife, such as a utility knife or a self-polished steel knife, to cut the rolled base paper layer by layer. But using a knife has many disadvantages: [0003] 1. There are potential safety hazards, and strict operation specification training is required for operators, and operators must also wear cut-resistant gloves. [0004] 2. Due to the manual operation, when the pa...
