Embossing device for use on paper towel processing equipment and embossing production technology thereof

Abstract

The invention provides an embossing device for use on paper towel processing equipment and an embossing production technology thereof. The device comprises a bottom roller; at least two embossing roller sets acted on the surface of the bottom roller are arranged along the axial direction of the bottom roller at the two sides of the bottom roller respectively; one embossing roller set is composed of one or more embossing roller assemblies, while the other embossing roller set is composed of two or more embossing roller assemblies; each embossing roller assembly is pressurized with an independent pressurizer respectively; and the embossing roller assembly at one side and the embossing roller assembly at the other side rotate by working with each other to form mutual complementation of embossed patterns. The segmented embossing is used, so that the line pressure in the embossing process is easy to control and convenient to adjust, and the embossed paper towel has better product quality and better effect; and more importantly, the diameter of the embossing roller assembly is much smaller than that of the integrated roller design in the prior art, so that the cost of manufacturing the embossing roller assembly and the cost of engraving flower patterns are also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of paper towel processing equipment, in particular to an embossing device used on paper towel processing equipment and an embossing production process thereof. Background technique [0002] Paper towels used in daily life, including toilet paper, facial tissue, napkins, etc., are mostly made of two or more layers of paper towels. In order to prevent the paper towels from easily peeling off during use, currently Advanced paper towel processing equipment is generally equipped with an embossing device for embossing multi-layer paper towels. The embossed pattern makes it difficult for multi-layer paper towels to peel off during use. At the same time, the colorful patterns can also become paper towels At present, the embossing device of the existing paper towel processing equipment generally adopts a double-roller embossing structure, that is, the double-roller consisting of a whole bottom roller set and a whole ...

AI Technical Summary

Problems solved by technology

However, with the development of society and the advancement of technology, manufacturers have higher and higher requirements for output, and tissue production equipment is becoming more and more large-scale. At present, the length of embossing rollers is generally set at about 2-3m, which is expensive. At the same time, its heat treatment is also difficult, and such a length design is difficult to ensure the consistency of the line pressure when embossing multi-layer tissue, because according to the mechanical properties, the longer the embossing roller is, the smaller the force on the middle part will be. In this way, the embossing effect on the middle part of the paper towel will be worse, and it often fails to meet the product processing requirements.

In order to solve this problem, many manufacturers try to increase the diameter of the embossing roller according to the aspect ratio of the embossing roller to meet the use requirements, but the cost of the embossing roller and the entire equipment will be higher; and once the embossing roller If the pattern or roll surface of the component is damaged, the entire embossing roll component must be replaced, which causes a great waste of resources
