Wide-width low-gram-weight paper roll dividing method and device

Abstract

The invention provides a wide-width low-gram-weight paper roll dividing method which is carried out in the following roll dividing device, the roll dividing device comprises a rack, a raw paper roll and a paper dividing roll are arranged on the rack, a paper tape adjusting device is arranged between the raw paper roll and the paper dividing roll, and the paper tape adjusting device comprises a raw paper roll unwinding roll, an angle fixing roll and a running paper roll winding roll; in the roll dividing process, a paper tape is led out from the lower end of a body paper roll, upwards makes contact with and passes through the upper end arc face of a body paper roll unwinding roll, upwards makes contact with and passes through the lower end arc face of an angle fixing roll, then makes contact with the upper end arc face of a running paper roll winding roll and is driven by power to pass through, and the paper tape is downwards wound on a paper dividing roll from the lower end. And an included angle is formed between a paper tape from the raw paper roll unwinding roller to the fixed-angle roller and a paper tape from the fixed-angle roller to the running paper winding roller. The problems of paper running deviation or pleating and even paper breaking in the roll dividing process are solved, the stability in the rolling process is improved, the end face flatness is improved, and the working efficiency is improved. The invention further provides a roll dividing device.

Description

technical field [0001] The invention relates to the technical field of paper-making and roll-splitting, and in particular provides a wide-width and low-grammage paper-splitting method, and also provides a roll-splitting device used for implementing the method. Background technique [0002] In the paper production process, large paper rolls with large diameters need to be divided into small paper rolls with different diameters. For the wide and low-weight paper with a width of 2.1-2.6 meters and a grammage of 30-55 g / m2, when the rolls of the base paper roll, the fixed roll, the transition roll and the newly formed paper roll The positional relationship between the rolls makes the angle formed between the base paper roll and the separation roll unsuitable. In addition, the paper is very wide and thin, which often causes the base paper roll to deviate or pleat when it is running. Even if the paper breaks, the machine has to be stopped for adjustment, which affects work effici...

Problems solved by technology

[0003] The purpose of the present invention is to provide a wide-width and low-grammage paper-splitting method, which solves the problem that the angle formed between the base paper roll and the separation roll is not suitable, which causes the paper to deviate or break when the base paper roll is divided into rolls. pleats, even paper break problem
