Description

Technical Field

[0001] The utility model relates to the technical field of ring spinning, in particular to a yarn guiding device for a drawing frame. Background Art

[0002] Ring spinning is the most widely used and common spinning method in the current market. The fiber strips after drafting of the sliver or roving are introduced into the ring wire ring through the rotation. The winding speed of the bobbin is faster than that of the wire ring, and the cotton yarn is twisted into fine yarn. It is widely used in various short fiber spinning projects. Such as carding, combing and blending. The wire ring is driven by the bobbin through the yarn strip to rotate around the steel collar. Twisting is performed. At the same time, the friction of the steel collar makes its rotation speed slightly lower than that of the bobbin to obtain winding. The spinning speed is high. The shape of the ring yarn is a conical spiral line with most fibers transferring inside and outside, so that the fibers are entangled and connected inside and outside in the yarn. The yarn has a compact structure and high strength, which is suitable for thread making, weaving and knitting and other products.

[0003] At present, after carding, multi-barrel slivers are fed into the draw frame through the guide rods of the draw frame. Since the slivers at the first guide rod are the largest and the heaviest, and there is also an angle difference from the guide rod to the feeding entrance of the draw frame, the slivers here are most affected by gravity and angle, and the sliver breakage rate is the highest. Therefore, a guide device for the draw frame is proposed to solve the above problems. Utility Model Content
