Description

Lifting mechanism of flax spinning frame

Technical Field

The utility model relates to a flax spinning frame's elevating system.

Background

Spinning machines are widely used in the textile industry to draw, twist and spin roving into spun yarn. The spinning frame consists of a feeding mechanism, a drafting mechanism, a twisting and winding mechanism and a winding and forming mechanism. The twisting and winding mechanism is provided with a yarn guide hook, a ring plate, a steel wire ring, a spindle, a yarn separating plate, a tape disk, a tension disk, a balloon ring and a bobbin. The spindle is driven to rotate by the spindle disc, the bobbin is arranged on the spindle, the spindle drives the steel wire ring to rotate around the steel collar through the yarn when rotating, the steel collar is a rotating track of the steel wire ring, one end of the steel wire ring is in contact with an inner side circular arc of the steel collar when the steel wire ring operates, and one twist is added to the drafted sliver by the steel wire ring when the steel wire ring rotates once. The ring is arranged in the ring plate, the ring plate is arranged in the cross arm of the ring plate, and the cross arm of the ring plate makes regular vertical lifting movement under the control of the winding forming mechanism, so that the spun yarn is wound on the bobbin according to the forming requirement. The movement of the ring plate comprises short stroke lifting and stepping, in the short stroke lifting movement, the speed of the ring plate is increased and decreased rapidly, so that the ring plate is wound into two different binding layers and winding layers, and in the stepping movement, after the ring finishes every short stroke lifting movement, the ring is lifted for a small distance, so that the spun yarn is wound to the upper part of the bobbin gradually. The guide wire guides the strands output by the front roller to the upper part of the spindle center line, the guide wire is connected to the guide plate, and the guide plate also performs regular vertical lifting motion under the control of the winding forming mechanism. The balloon ring is lifted and lowered along with the ring according to a certain rule, so that the tension of the balloon ring can be controlled and broken ends can be reduced. In the prior art, the transmission mechanism drives the transmission shaft to rotate in a reciprocating manner in the lifting motion process of the winding forming mechanism, so that the over-travel damage is often caused because the rotation is excessive but unknown.

Meanwhile, in the prior art, the winding forming mechanism controls the lifting motion of the ring rail, the yarn guide plate and the ring in a forming cam mode, so that cop cannot be formed well and spinning quality is not high.
