Automatic weft straightening equipment for wall coverings

Abstract

The invention discloses automatic weft straightening equipment for wall coverings. The automatic weft straightening equipment for the wall coverings comprises an equipment machine frame and two sets of differential weft straightening device. The two sets of symmetrically arranged differential weft straightening devices are installed on the equipment machine frame, synchronous side edge positioningdevices are separately arranged on the front side and the back side of the equipment machine frame, and a first imaging assembly and a second imaging assembly are installed on the equipment machine frame to image and monitor the wall coverings. The structure is novel, skewing positions and skewing degrees of the wall coverings are positioned and monitored through the imaging assemblies, and thenthe two symmetrically installed differential weft straightening devices generate pulling force on the wall coverings to perform the weft straightening operation to correct the skewing of the wall coverings; and the synchronous side edge positioning devices are arranged, during the weft straightening operation, the side edges of the wall coverings can be effectively clamped and positioned, so thatthe wall coverings maintain the overall stability during the weft straightening operation, the effect of the weft straightening operation is improved, and it is guaranteed that the wide sizes of the widths of the wall coverings do change under the action of the weft straightening force.

Description

technical field [0001] The invention relates to the technical field of wall cloth production equipment, in particular to an automatic weft adjustment device for wall cloth. Background technique [0002] Wall cloth, also known as "wall cloth", is a decorative fabric pasted on the wall. Cotton cloth is often used as the base cloth, and printed or embossed embossing is applied to the base cloth, and jacquard is also used. The patterns are mostly geometric figures and floral patterns. [0003] Weft skew is the fabric structure of the fabric and the cloth fiber of the knitted fabric presents a slanted state, or the fabric structure is twisted. This phenomenon is called weft skew. There are generally two reasons for the weft skew of textiles. One is in the textile manufacturing process. During the process, due to improper handling, a large internal stress is generated, resulting in weft skew. The second is that in the post-processing of textiles, such as dyeing and printing, due...

Problems solved by technology

The second is that in the post-processing of textiles, such as dyeing and printing, due to improper tension adjustment, wall coverings, as a kind of textiles, will inevitably have weft skew problems. Wall coverings with too large weft slopes are defective products. Weft inclination increases the difficulty of wall covering construction to a certain extent. If the problem of weft inclination is not properly dealt with during construction, it will affect the overall effect of wall covering on the wall, making the pattern of wall covering not neat enough and affecting the appearance, especially for The effect of vertical striped wall covering is particularly obvious
