Doubling roving integrated sample weaving machine

Abstract

The invention discloses a doubling roving integrated sample weaving machine. The machine comprises a guide frame, a stretching mechanism and a twisting coiling mechanism which are intercommunicated through cotton strips; a guide roller is fixed above the guide frame; the twisting coiling machine comprises a flyer bobbin, and a spindle fixed on the flyer bobbin; the stretching mechanism comprises rocking frame fixing supporting rod; a fourth roller, a third roller, a second roller and a front roller are sequentially arranged at the right side of the rocking frame fixing supporting rod; a rubber roller which is in contact with the surface of each roller is arranged right above each roller; a pin bar and a leather ring are respectively arranged above and below the third roller; a plurality of cotton strips which are parallel to each other sequentially pass through the surfaces of the fourth roller, the third roller, the second roller and the front roller, respectively in contact with a rubber roller A, a small iron roller, a rubber roller C and a rubber roller D; one of the ends of the cotton strips is connected with the guide frame through the guide roller, and while the other one of the ends of the cotton strips passes through a collecting pipe to be connected with the flyer bobbin. The rough yarns produced by the machine are of a double-strand structure, and therefore, the fine yarn quality and machine efficiency are increased, and the spinning processes are decreased.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a small integrated prototype of drawing frame and roving frame. Background technique [0002] At present, the tasks of the roving process in the spinning process mainly include: 1. Drafting: stretching the cotton sliver into roving; 2. Twisting: adding a certain twist to the roving to improve the strength of the roving; to avoid winding and unexpected elongation during unwinding, and prepare for spun yarn drafting; 3. Winding: winding the twisted roving on the bobbin to make a package of a certain shape and size for storage, handling and Adapted to the feeding on the spinning frame. [0003] However, the drafting ratio of the roving frame in the prior art is small, generally between 4-13 times, and the quality requirements for the fed sliver are high, leading to the drawing process before the roving process to improve the quality of the sliver , thus prolonging the...
