High-speed vacuum cylinder paper machine

Abstract

The invention provides a high-speed vacuum cylinder paper machine. The high-speed vacuum cylinder paper machine comprises a vacuum cylinder forming part, a vacuum pressing part, a wet paper web transferring part, a drying part, a paper guiding part and a paper winding part, wherein the vacuum pressing part is installed on the rear side of the vacuum cylinder forming part; the wet paper web transferring part is installed between the vacuum pressing part and the vacuum cylinder forming part; the drying part is installed on the rear side of the vacuum pressing part; the paper winding part is installed on the rear side of the drying part; and the paper guiding part is installed between the paper winding part and the drying part. According to the high-speed vacuum cylinder paper machine, through the structural optimization design of the vacuum cylinder forming part, the wet paper web transferring part, the drying part and the paper guiding and winding parts, the position of a vacuum cylinder is adjustable, the paper sheet forming quality is good, a wet paper web and a dry paper web are not prone to paper breaking in a transferring process, the drying efficiency is high, and high-speed and high-quality production of toilet paper can be achieved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a high-speed vacuum cylinder paper machine. Background technique [0002] At present, the forming methods of domestic toilet paper machines mainly include ordinary cylinder former and fourdrinier. The biggest defect of cylinder forming is that the speed of the machine is difficult to increase due to the limitation of centrifugal force. Among them, the pressure cylinder former and the suction cylinder former The speed of the vehicle is limited to below 200m / min, the working speed is low, the energy consumption is high, and the efficiency is low. Higher papermaking speed is the key factor to improve production efficiency. Fourdrinier paper machine can increase the speed, but it occupies a large area and has high operating costs. Generally, it is not used for papermaking thin paper. [0003] The working process of the existing rotary paper machine is that the pulp slu...

AI Technical Summary

Problems solved by technology

[0004] The existing cylinder paper machine mainly has the following defects: 1) The position of the vacuum cylinder cannot be adjusted, the quality of the paper sheet is poor, the paper is easy to break when the wet paper web is transferred, and the speed is low; The surface is easy to adhere to fine fibers. If the fine fibers are not removed in time, it will have a bad influence on the evenness of the paper sheet; after the transfer felt has been running for a long time, it will absorb the moisture in the slurry. The adhesion of the felt is reduced, and the wet paper web is easy to break during the transfer process; 3) The drying efficiency is low, the energy consumption is large, and the increase in speed is restricted; 4) The process of transferring the dry paper web from the drying section to the paper section Easy to break paper
