Problems solved by technology

However, the felt on the press section often loosens, and the transmission path deviates, which affects the entire pressing process, and then causes the dryness of the base paper to drop significantly after pressing, failing to achieve the expected goal

Abstract

The invention discloses a press dewatering system in a paper machine structure for artificial board facing body paper production. The press dewatering system comprises a paper guide roll, a vacuum suction moving press roll, a vacuum press roll, a stone roll, a double scraper, a spraying device, a blind hole roll and coarse cotton cloth. Guide rolls are arranged in a first coarse cotton cloth loop, a second coarse cotton cloth loop and a third coarse cotton cloth loop in a transmission mode, and the first coarse cotton cloth loop, the second coarse cotton cloth loop and the third coarse cotton cloth loop are provided with tensioning devices, correcting devices, water absorbing tanks and water receiving trays. According to the press dewatering system, three pieces of coarse cotton cloth are adopted in the whole press part, and thus the press speed is increased; the tensioning devices and the correcting devices cooperate to adjust the coarse cotton cloth, the tensioning devices control the tension of the coarse cotton cloth to prevent the coarse cotton cloth from loosening, and the correcting devices detect the conveyed coarse cotton cloth and can correct the advancing path of the coarse cotton cloth and prevent the coarse cotton cloth from deflecting; meanwhile, the press dewatering system can reduce energy consumption and obviously increase the dryness of body paper after press, and has significant economic benefits.

Description

technical field [0001] The invention relates to the technical field of paper press dewatering, in particular to a press dewatering system in a paper machine structure for the production of wood-based panel veneer base paper. Background technique [0002] The main component of paper is plant fiber, and plant fiber is a kind of hydrophilic substance, which has the characteristics of swelling when absorbing water and shrinking when losing water. [0003] The expansion rate of paper refers to the relative change in size of paper after soaking in water at a certain temperature or after soaking in water and air-drying, expressed as a percentage of the size increase or decrease to the original sample size. [0004] The expansion rate of printing paper has an important influence on printing. For example, as offset printing paper for multi-color overprinting of high-end books, magazines, covers, and illustrations, as transfer printing paper for textile printing and dyeing, etc., its...
