Description

Arc roller set with adjustable radian

Technical Field

The invention particularly relates to an arc roller set with adjustable radian.

Background

The axial curvature radius of the arc-shaped roller is equal, the axial speed of each point of the roller surface is constant, the arc-shaped roller is provided with a concave-convex surface in a geometrical structure, the concave-convex surface is the basis for the paper web to be unfolded, if the paper web enters the concave surface and enters the convex surface through the roller surface, the paper web is unfolded, the unfolding amount of the paper web depends on the tension, wrap angle, bending amount and the like of the paper web, and the bending amount is one of important factors for determining the maximum unfolding of the paper web through the surface of the arc-shaped roller, because 1, the transverse unfolding amount at the center line of the paper web is zero; 2. the stretching roller generates a y transverse stretching amount at the position of the arc roller surface and the X distance from the center line of the paper web; 3. the spreader roll produces a 2y lateral spread along the curved roll web centerline at a distance of 2X. Proportional transverse stretching can be strengthened by the way that the paper web contacts the roller, and due to the maximum transverse stretching amount of the two ends of the paper web, the paper web always contacts the two ends of the roller surface firstly, so that the two ends of the paper web are firstly stretched from the concave edge to the convex edge to form a certain space, and then the generated transverse vector is filled. Due to inherent geometrical reasons the web is always stretched proportionally, not from the middle, because no wrinkles of the web are created during the stretching of the curved roll.

When the existing arc-shaped stick leaves a factory, the bending amount of the arc-shaped stick is fixed, and in the actual use process, under the conditions of different paper materials, thicknesses and different unfolding requirements, the use requirements can be met only by customizing and replacing the arc-shaped stick with the corresponding bending amount; like this the first equipment input cost that has increased, the second need be changed the arc rod, increases workman's work load, has prolonged production cycle.
