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. ;

Embodiment 1

[0086] like Figure 1-Figure 6 As shown, the present invention discloses a crepe paper manufacturing system based on speed difference creping. In a specific embodiment of the present invention, it includes a creping device with a frame;

[0087] The creping device includes a paper web input mechanism 11, a drying cylinder 12 and a vacuum creping roller 13; the paper web input mechanism 11, the drying cylinder 12 and the vacuum creping roller 13 are installed on the frame in sequence;

[0088]The vacuum creping roller 13 and the drying cylinder 12 squeeze each other, and the rotation speed of the vacuum creping roller 13 is lower than the rotation speed of the drying cylinder 12 to generate a speed difference. During the process of wrinkling, the dryer will heat the wet paper sheet, and in the process of heating and squeezing, the effect of hot ironing and ironing will be formed, so that the paper can directly reach one step. The effect of forming, the wrinkling effect of this...

Embodiment 2

[0114] In a specific embodiment of the present invention, a method for forming paper is included, and the method for forming paper includes the following steps:

[0115] A1 Preparing wet paper web: The pre-prepared pulp is formed into a wet paper web by a forming machine;

[0116] A2 conveying: convey the formed wet paper web to the dryer for dehydration;

[0117] A3 Pre-adjustment: start the ventilation part, and the ventilation part inhales or evacuates the vacuum volume adjustment space;

[0118] A4 creping: the vacuum creping roller 13 and the drying cylinder 12 are pressed against each other, so that the paper web is adsorbed on the surface of the vacuum creping roller 13. The rotation speed of the vacuum creping roller 13 is lower than the rotation speed of the drying cylinder 12, resulting in a speed difference, and the wet paper The web is stacked and crimped at the squeeze of the vacuum creping roll 13 and the dryer 12;

[0119] A5 Drying: After the wrinkled paper w...

Abstract

The invention relates to a crepe paper manufacturing system based on speed difference wrinkling. The crepe paper manufacturing system is characterized by comprising a wrinkling device with a rack; 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 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 tissue paper is creped by the traditional light dry creping process (LDC). The steps of this process are: [0003] The pulp in the pulp head box is formed into an initial paper web on a fourdrinier paper machine and other similar papermaking equipment, and the initial paper web is transferred to the absorbent felt through a guide roll, and is close to the surface of the absorbent felt for dewatering; then wet paper sheets After being pressed by the guide roller and the pressing roller, it is transferred to the surface of the hot dryer for drying; finally, the scraper is pressed against the surface of the web and has a strong collision with the web to wrinkle the web, which can increase the bulk and softness of the paper. . [0004] W...
