Bobbin yarn unwinding air ring control device and bobbin yarn unwinding equipment

Abstract

The invention discloses a bobbin yarn unwinding air ring control device and bobbin yarn unwinding equipment. The bobbin yarn unwinding air ring control device comprises a rack, a height adjusting mechanism and an unwinding device, the rack is provided with a placing station for placement of bobbin yarn, the height adjusting mechanism comprises an adjusting plate, a limiting plate and a height adjusting driving part, the limiting plate is arranged on the rack and provided with a limiting channel extending in the vertical direction, the adjusting plate is partially arranged in the limiting channel, and the height adjusting driving part is connected to the adjusting plate and used for driving the adjusting plate to move. The bobbin yarn unwinding equipment comprises a winding device and the bobbin yarn unwinding air ring control device. The bobbin yarn unwinding air ring control device can stabilize a yarn unwinding air ring, the air ring unwinding effect is good, tension on the bobbin yarn is not prone to sudden change in the unwinding process, the phenomena of yarn breakage, damage and hairiness increase are avoided, the product quality is improved, and the unwinding efficiency is improved.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a cop yarn unwinding balloon control device and cop yarn unwinding equipment. Background technique [0002] In the textile industry, such as winding and loosening processes, it is necessary to wind the yarn on the bobbin on the bobbin to form a bobbin. During the specific operation, the cop yarn is fixed on the yarn seat, and the thread end is drawn out. The thread end passes through the unwinder, the tension controller, etc., and under the guidance of the groove drum and the yarn guide element, the yarn is cross-wound on the bobbin according to certain requirements. superior. During this process, when the yarn is pulled out at high speed, it forms an upward spiral motion, forming one or more balloons. If the distance between the unwinder and the bobbin remains unchanged, the diameter of the bobbin decreases when unwinding, and the number of unwinding balloons will increase due...

AI Technical Summary

Problems solved by technology

Changes in the number of unwinding balloons directly affect the yarn tension, resulting in uneven yarn density inside and outside the produced bobbins, which will also lead to sudden changes in the tension of the yarn on the bobbin during the unwinding process, resulting in yarn breakage, damage and Increased hairiness, reducing product quality and efficiency
