Description

Yarn tension compensator

Technical Field

The invention belongs to the technical field of yarn processing, and relates to a yarn tension compensator.

Background

The yarn tension has extremely important influence on yarn forming, particularly on a twisting machine, the tension of single-strand yarns can be changed in the twisting process, so that the requirements on the tension of inner and outer yarns are high, and the balance of the tension of the inner and outer yarns is a precondition for producing high-quality yarns and is also a key for ensuring the quality of final finished products. Tension in yarn twisting influences twisting firmness, elasticity, twisting uniformity and strength of final yarn, excessive yarn tension has a negative effect on the formation of a balloon during yarn starting, and the success rate of spindle starting is influenced finally. Therefore, a tension adjusting device is installed in the twisting machine, but the existing twisting machine has the defects of low automation degree of tension adjustment and time and labor waste in the adjusting process.

Furthermore, the section of the lifting rod is L-shaped, and the section of the slide guide hole is L-shaped.

Furthermore, a groove is formed in the contact surface of the clamping plate and the limiting block, and a plurality of adjusting rubber sheets are arranged in the groove. Because the clamping plate is fixed on the limiting block through the bolt, if the size of the guide sliding hole needs to be adjusted, the rubber sheet can be increased or decreased or adjusted to adjust the size of the guide sliding hole.

Furthermore, the roller surface of the guide roller is provided with spiral lines. The yarn is wound on the grain path, and the yarn is prevented from slipping and shifting when the guide roller rotates, so that the yarn can be accurately fed between the two limiting rollers.

Furthermore, be equipped with spacing arch and lower spacing arch on the lifter respectively, go up spacing arch and lower spacing arch homoenergetic and support with the grip block and lean on.

The yarn passes through the strip-shaped yarn passing hole of the tension adjusting roller, then passes around the grains of the guide roller and finally passes through the two limiting rollers. When the tension of the yarn is normal, the yarn acts on the limiting roller, the lifting rod moves downwards to compress the spring, the strip-shaped wire passing hole of the tension adjusting roller is in a horizontal state, and the rubber roller is not stressed by the yarn. When the tension of the yarn is too small or the tension is lost, the pressure on the limiting roller is reduced, the lifting rod moves upwards, the rack can drive the linkage gear to rotate, the tension adjusting roller is driven to rotate, the strip-shaped wire passing hole is inclined to tighten the yarn, the friction force between the rubber roller and the yarn is increased, and the yarn is tightened again. When the yarn at the position of the limiting roller completely recovers normal tension, the lifting rod automatically moves downwards under the pressure of the yarn, and the tension adjusting roller rotates to loosen the yarn.

Compared with the prior art, the yarn tension compensator has the following advantages:

1. rely on the cooperation drive lifter of spring and yarn pressure to reciprocate, the tension of automatic balance yarn adjusts the precision height, and the lifter only needs to remove a segment distance, just can rotate the tension adjusting roller by a wide margin, need not artificial intervention.

2. Through rotating the tension adjusting roller, the inclination angle of the line hole is changed by the strip, and then the path of the yarn and the friction force of the rubber roller are changed.
