Description

Wiping paper forming net

Technical Field

The utility model relates to a papermaking equipment technical field especially relates to a wiping paper forming wire.

Background

The paper making plant now carries out the process of converting pulp into paper by a series of devices and processes, of which the fourdrinier wire forming dryer is the most important device, in the paper making process, the pulp is conveyed to a head box and sprayed onto a forming wire surface by the head box, the forming wire is a woven endless wire belt, the forming wire runs in a loop at a certain speed between a plurality of guide rollers such as breast roller, couch roller, drive roller and guide roller, various dewatering devices on the wire table are positioned at the lower side of the forming wire contacting with a bottom layer, such as a suction box and a water scraping plate, the pulp is sprayed onto a paper forming surface layer of the forming wire belt, the moisture and other liquids in the pulp are filtered during the running of the wire belt, the raw material fibers in the pulp are separated from a water medium, a wet paper web is formed on the paper forming surface layer of the forming wire, and the wet paper web is transferred into a pressing zone by a transfer device after the vacuum couch roller, the wet paper web is separated from the forming area and then enters a pressing area, a pressing felt is arranged in the pressing area, the pressing felt runs between one or more groups of pressing rollers in a ring shape at a certain speed, the pressure from the pressing rollers removes the excessive moisture in the wet paper web, the removing capacity of the excessive moisture in the wet paper web is enhanced through the pressing felt, the wet paper web is conveyed to a drying area after passing through the pressing area, the moisture in the paper web is further removed in the drying area, and the processing and packaging requirements of the subsequent process are met; one of the weaving methods of the existing papermaking forming net is that the warp threads woven by a flat weaving method are consistent with the yarns in the running direction when the existing papermaking forming net is used on a paper machine, the weft threads are consistent with the sheet-shaped mesh belt in the vertical running direction when the existing papermaking forming net is used on the paper machine, and then the sheet-shaped mesh belt is changed into an endless annular mesh belt by a splicer L sequence generally known in the industry, and the other method is that the warp threads woven by the endless weaving method are consistent with the yarns in the vertical running direction when the existing papermaking forming net is used on the paper machine, and the weft threads woven by the endless weaving method are consistent with the yarns in the running direction when the existing papermaking forming net is used on the paper machine, so that the existing papermaking forming net has the defects that: the number of fiber supporting points is small, the fiber retention rate is low, the surface is rough, paper sheets have net marks, and paper is difficult to peel; the formed sheet had low stiffness, and the smoothness of the paper surface was insufficient, resulting in poor tactile sensation.
