Hot-rolling device for producing three-dimensional roll compacting composite material

Abstract

The invention discloses a hot-rolling device for producing a three-dimensional roll compacting composite material. The hot-rolling device comprises a hot rolling pressure roller, the surface of the hot rolling pressure roller is covered with a pattern layer, several groups of first helical lines which helically protrude in the anti-clockwise direction and surround the pressure roller and several groups of second helical lines which helically protrude in the clockwise direction and reversely surround the pressure roller intersect with one another to form the pattern layer, the included angle [alpha]1 between each first helical line and the horizontal direction ranges from 0 degree to 90 degrees, the included angle [alpha]2 between each second helical line and the horizontal direction ranges from 0 degree to 90 degrees, intersection points of the first helical lines and the second helical lines are embossing points. On the basis of the existing hot rolling device, the pattern of the pressure roller is changed. Several sets of helical projections which are in inverse surrounding directions intersect with one another to form point pressure. In this way, the rolled non-woven fabric has a three-dimensional effect, the front and back sides have the same smoothness and consistent pattern and hand feeling, and the hot-rolling device can be better applied to the industry demand.

Description

technical field [0001] The invention relates to a hot rolling device, in particular to a hot rolling device for producing three-dimensional rolling composite materials. Background technique [0002] In the production process of non-woven fabrics, it is often necessary to adopt a hot-rolling process for reinforcement. After a suitable hot-rolling process, the prepared non-woven fabrics can achieve the required strength and obtain the required pattern. At present, the commonly used hot rolling device, the pressure roller is smooth or has a specific pattern. During hot rolling, the two sides of the nonwoven fabric are subjected to different forces and temperatures, resulting in differences in the smoothness and feel of the two sides of the fabric. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a hot rolling device for producing three-dimensional rolled composite materials.
