Adjustable-feeding greige cloth dual unwinding machine

Abstract

The invention discloses an adjustable-feeding greige cloth dual unwinding machine and relates to the technical field of textile machinery, in particular to structural technology of a greige cloth unwinding machine. The machine comprises two sets of machine frames in pair, wherein upper cloth guide rollers, a middle cloth guide roller, a lower cloth guide roller, a balance cloth guide roller and a bottom cloth guide roller are arranged on each set of machine frames through bearings respectively; two upper cloth guide rollers are symmetrically arranged on the machine frame; a retractable cloth guide roller is arranged below the middle cloth guide roller; the two ends of the retractable cloth guide roller are supported on a pair of movable bearing blocks respectively; the two sets of movable bearing blocks are connected with the expansion links of two sets of air cylinders respectively; and the two sets of air cylinders are fixedly supported on the two sets of machine frames respectively. The two ends of the retractable cloth guide roller are controlled by the air cylinders, so that the expansion amount of the cloth guide roller can be adjusted conveniently, cloth is fed conveniently, discharge time can be saved greatly, discharge working efficiency can be improved, and unwinding quality can be improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to the structural technology of a cloth unwinding machine. Background technique [0002] There is an unwinding process in the textile processing process, which needs to release the cloth blank wound on the cloth shaft for subsequent processing, which is generally realized by an unwinding machine. In order to improve the production efficiency of unwinding, a double unwinding machine has emerged as the times require. Two upper cloth guide rollers are arranged symmetrically on the frame, and two sets of unwinding racks are respectively arranged on the two outer sides of the two upper cloth guide rollers. , a pair of cloth shaft brackets are respectively supported by bearings on each discharge rack, and the discharge racks on both sides can implement discharge successively. [0003] Because the blanks need to be drawn out from the cloth guide shafts before the unwinding work,...

AI Technical Summary

Problems solved by technology

[0003] Because the blanks need to be drawn out from the cloth guide shafts before the unwinding work, because the distance between one set of upper cloth guide rollers and the shared lower cloth guide rollers is relatively long, the cloth blanks are easily pulled out due to gravity when unloading. Drooping occurs, which directly affects the unwinding quality
