Spreader

Abstract

The invention relates to a fabric spreading machine and belongs to the technical field of textile printing and dyeing machinery. The fabric spreading machine comprises a machine frame, a fabric guide mechanism, a fabric spreading mechanism, an untwisting device, an automatic deflection detection and correction device and a guide-out roller. The fabric spreading machine is characterized in that the untwisting device comprises an untwisting frame base, an untwisting frame, a detection roller, an untwisting fabric guide wheel, a rotary cylinder bearing block, a rotary cylinder, a rotary disk, a pair of untwisting transition wheels and an untwisting servo motor, the untwisting frame base is composed of a first ladder, a second ladder and a platform, one side of a left wallboard of the untwisting frame is provided with a first signal collector, one side of a right wallboard of the untwisting frame is provided with a second signal collector, a first signal trigger coil is fixed to the left end of the detection roller, and a second signal trigger coil is fixed to the right end of the detection roller; the fabric spreading mechanism comprises a first fabric stretching roller, a second fabric stretching roller, a tension roller, a fabric stretching roller driving device, a tension roller driving device and a pair of tension roller manual adjustment devices. The structure is simplified, the response speed of the first signal collector and the response speed of the second signal collector are increased, and reliability of the first signal collector and the second signal collector is improved; deflected fabric is corrected automatically, and strength is relieved; selvages will not curl.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing machinery, and in particular relates to a spreading machine. Background technique [0002] The aforementioned spreading machine is also called an open-width machine, a stretching machine or a stretcher, and the like. As known in the industry, the fabric obtained from the previous weaving process needs to be processed in subsequent processes, such as wet finishing (such as silicone soft finishing) process, after wet finishing, the fabric needs to be dehydrated by calendering or centrifugal dehydration. Because the shape of the fabric changes to a certain twist in the wet finishing and dehydration process, figuratively speaking, the shape of the fabric is like the state of fried dough sticks in daily food. If it is not untwisted, it cannot enter the subsequent process such as drying. Drying, falling cloth, winding process. [0003] The untwisting device and the centering device...

AI Technical Summary

Problems solved by technology

Although this processing method can correct the traveling track of the fabric, it causes a waste of valuable labor resources.

Since the deviation needs to be manually corrected by the worker, the labor intensity of the worker is high

In addition, it is difficult to achieve a satisfactory level of human error correction, because human error correction is affected to a certain extent by factors such as workers' experience differences, differences in responsibility, and emotional changes.
