Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile production technology, and specifically relates to a telescopic yarn tension control device for a tension sheet type warping machine. BACKGROUND

[0002] In the warping process of the textile production process, the traditional warping machine generally adopts a tension sheet type tension control and adjustment method, which controls the tension of the yarn during unwinding by adjusting the number of tension sheets, adjusting the distance between the yarn spindle foot and the guide hole. This tension control and adjustment method is prone to accumulate fly on the tension sheet, causing high channel resistance and high yarn breakage. Moreover, when adjusting the distance between the spindle foot and the guide hole according to the size of the cone yarn and the number of warp yarns, the chain wheel behind the creel needs to be rotated, which is relatively laborious to operate. Furthermore, during the production of strand yarn or strong twist yarn, small braided yarn problems are prone to occur when the joint is slowed down because the yarn twist is large and the tension is high. In summary, the control device of the tension sheet type has poor control over the yarn, cannot solve the small braided yarn defect, and has a great impact on the quality and efficiency of subsequent sizing and weaving production.
