Crepe paper manufacturing system and manufacturing method based on speed difference wrinkling

Abstract

The invention relates to a crepe paper manufacturing system based on speed difference wrinkling, wherein the system is characterized by comprising a wrinkling device with a rack, and the wrinkling device comprises a paper web input mechanism, a drying cylinder and a vacuum wrinkling roller; the paper web input mechanism, the drying cylinder and the vacuum wrinkling roller are sequentially mounted on the rack; and the vacuum wrinkling roller and the drying cylinder extrude each other, and the rotating speed of the vacuum wrinkling roller is lower than that of the drying cylinder, so that speed difference is generated, and paper wrinkling forming is achieved. The system is high in practicability and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a crepe paper manufacturing system and a manufacturing method thereof based on speed difference creping. Background technique [0002] General household paper uses the traditional light dry creping process (LDC) to wrinkle the paper. The steps of this process are: [0003] The pulp in the pulp head box is formed into the initial paper web on the fourdrinier paper machine and other similar papermaking equipment, and the initial paper web is transferred to the absorbent felt by the guide roller, and is attached to the surface of the absorbent felt for dehydration; then the wet paper sheet After being pressed by guide rollers and pressing rollers, it is transferred to the surface of the hot dryer for drying; finally, the scraper clings to the surface of the paper web and strongly collides with the paper web to make the paper web wrinkle, and wrinkle can increase the bulk and sof...

AI Technical Summary

Problems solved by technology

[0006] First, after initial wrinkling, the effect of wrinkled paper recovery will appear after drying traction and drying, resulting in poor quality of wrinkled paper produced;

[0007] Second, in the process of the scraper colliding with the surface of the paper web, it will cause defects in the paper web and cause the paper web to break;

[0008] Third, the dry paper web is wrinkled by scraper creping. In this way, a lot of paper scraps will be left on the scraper after long-term use, which requires frequent cleaning or replacement of the scraper, and dust will be generated, which will affect the working environment of the workshop. ;
