Problems solved by technology

However, from the analysis of the force when the mesh passes through the unfolding roller, it is found that when the unfolding direction of the oblique embossing is the same as the rotation direction of the unfolding roller, it is not conducive to the unfolding of the mesh cloth.

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 Schematic diagram of force analysis after installation using the existing installation method for the unrolling roll, as shown in figure 1 As shown, when the flexible and thin material passes through the surface of the sleeve 3' of the unrolling roller (the film advances in the direction of V'), the friction of the flexible and thin material drives the sleeve 3' to rotate, and the thread arrow formed when the thread 4' intersects The direction pointed is the same as the moving direction of the thin material, that is, when the direction pointed by the thread arrow is the same as the rotation direction of the sleeve, it passes through the unfolding roller under the action of warp tension, and the flexible thin material in the contact part with the th...

Abstract

An embodiment of the invention discloses an installation method of an unwinding roller. The installation method includes that a bearing seat is fixed on a proper position; a sleeve is installed in a main shaft in a sleeved mode, at least two threads are symmetrically arranged on the surface of the sleeve, and the threads are intersected to form a thread arrow; and the main shaft is installed on the bearing seat to enable the direction pointed by the thread arrow on the sleeve to be opposite to the rotating speed of the sleeve. The installation method can effectively achieve unwinding and wrinkle eliminating functions of flexible thin materials, and is convenient to operate and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of winding and wrinkle removal, in particular to an installation method of an unwinding roller. Background technique [0002] Spreading roller (also known as: crease-removing roller, stretching roller, expanding roller, opening roller, stretching roller) is used for weft expanding, flattening and eliminating wrinkles of open-width fabrics (such as cloth), and it is also suitable for paper , film, metal foil and other thin materials. Widely used in printing and dyeing, artificial leather and other industries, such as desizing, rinsing, scouring, weft trimming, sanding, winding, printing, gluing, coating and other equipment. In industrial production, when continuous winding of flexible and thin materials such as film, fabric, paper, etc., wrinkles often appear on the surface of the material. The main reason for wrinkling is that due to the influence of mechanical and chemical effects, the warp tension at eac...
