Embossing or calendering device

Abstract

The invention provides an embossing or calendering device, which comprises an embossing or calendering roller, at least one smooth roller cooperated with the embossing or calendering roller for embossing or calendering and a jacking device for driving the smooth roller to be tightly attached to the embossing or calendering roller, wherein the smooth roller can be flexibly deformed to keep tight attachment to the embossing or calendering roller under the driving and pressing action of the jacking device. After the above structural form is adopted, since the smooth roller is always jacked by the jacking device during embossing or calendering and the rigidity of the smooth roller is relatively low, when a gap exists at a position between the embossing or calendering roller and the smooth roller, the corresponding part of the smooth roller is jacked by the jacking device to immediately deform, so that the gap at the position disappears, and the uniformity of the embossing or calendering effect of a flexible material is ensured.

Description

technical field [0001] The invention relates to the technical field of paper, non-woven fabrics, leather, etc. processing, in particular to an embossed or embossed [0002] Light device. Background technique [0003] In the process of embossing or calendering of flexible materials such as paper, non-woven fabrics, and leather, steel embossing or calendering rollers are generally used in conjunction with smooth rollers for embossing or calendering. Calendering quality, the higher the processing accuracy of the end surface of the embossing or calendering roller and the smoothing roller, the better, so that the embossing or calendering roller can be completely attached to the smoothing roller during embossing or calendering, so as to ensure uniform embossing effect unanimous. However, in practice, due to the long axial dimension of the embossing or calendering roller and the smooth roller for embossing or calendering, it is difficult to ensure the overall processing accur...

AI Technical Summary

Problems solved by technology

However, in practice, due to the long axial dimension of the embossing or calendering roller and the smooth roller for embossing or calendering, it is difficult to ensure the overall processing accuracy; The light roll is in a state of high-speed rotation, and there is movement between the embossing or calender roll and the light roll, so it is impossible to avoid local embossing or unevenness of the flexible material
