Example Embodiment

[0103] Example 2

[0104] A method for producing a wrinkled paper based on a speed difference, which is suitable for the above-described wrinkle fabric manufacturing system, characterized in that the method comprising a paper molding comprises the step of:

[0105] A1 preparatory wet paper: The pre-prepared pulp is formed into a wet paper web through the molding machine;

[0106] A2 delivery: Transfer the molded wet paper to the dryer for dehydration;

[0107] A3 wrinkles: Mutually extruded by the vacuum wrinkle roller 13, so that the web is adsorbed in the surface of the vacuum wrinkle roller 13, the rotational speed of the vacuum wrinkle roller 13 is lower than the rotational speed of the dryer 12, wet paper A stack is stacked at the extrusion of the vacuum wrinkle roller 13 and the dryer 12;

[0108] A4 drying: After the wrinkled web is adsorbed by the vacuum wrinkle roller 13, the drying apparatus is delivered to the drying device for drying, drying simultaneously, through the...

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...
