Embossing method for tissue paper making

Abstract

The invention relates to the technical field of tissue paper making, and concretely relates to an embossing method for tissue paper making. The method comprises the following steps of receiving a tissue paper web, wherein a transfer roll receives the upstream formed tissue paper web and sends the tissue paper web onto the surface of a drying cylinder; setting a pattern, wherein a controller controls corresponding first controllable air holes to open according to the preset pattern; adsorbing for embossing, wherein a suction ventilator inwards suck air through the first controllable air holes, adsorbs the tissue paper web on the surface of the drying cylinder, and downwards sucks the tissue paper web at the corresponding parts of the first controllable air holes so as to form a concave-convex floral pattern; drying for forming, wherein the drying cylinder heats the tissue paper roll to dry the tissue paper roll and finalize the pattern; and outputting the tissue paper roll, wherein the downstream transfer roll transfers the tissue paper web onto a downstream device. The embossing method for tissue paper making provided by the invention can solve the problems that the processing flows are multiple and the production efficiency is reduced since tissue paper needs to be separately embossed in an existing household tissue paper manufacturing device.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an embossing method for papermaking. Background technique [0002] Household paper is widely used in daily life, such as facial tissue, toilet paper, wiping paper, etc. are well known to the public. In the manufacturing process of tissue paper, in order to improve certain physical properties of tissue paper, such as bulkiness, water absorption, etc., and to increase the aesthetics of tissue paper, after the production of tissue paper is completed, it will be processed in the post-processing section Emboss the paper. [0003] The embossing process in the processing section usually makes the paper pass through the embossing nip formed by two rollers to achieve the purpose of forming patterns on the surface of the paper, one or two of which are provided with raised or depressed embossed patterns on the surface. [0004] Although the existing embossing process can form the requ...
