A Compensable Equilibrium Winding Hysteresis Tensioner Used in Textile Machinery

Abstract

The invention discloses a compensable balanced winding hysteresis tensioner for textile machinery, which is a compensable balanced winding magnetic hysteresis tensioner suitable for a variety of textile machinery when flexible materials are passively drawn and wound. Hysteresis tensioner. In the present invention, the length-to-diameter ratio of the helical permanent magnet steel and the hysteresis tube is ≥3, and the hysteresis torque is homogenized within the adjustment range with the large pitch of the multi-head screw, so that the non-linearity is improved and the tension adjustment range is expanded at the same time; the design of the helical permanent magnet The steel has an even number of turns, and the circumferential angles of N poles and S poles alternating between the two turns are offset by half a bit, which balances the gap between the hysteresis force of N poles and S poles and improves the fluctuation of tension pulse vibration; the design has a built-in automatic The excitation induction coil, compensation coil and automatic compensation closed-loop group control system can not only compensate for time aging, but also eliminate consistency differences; single control and group control can be used for dual purposes to avoid scrapping. Because the textile machine tensioner has a wide range of applications and a large number, the present invention is easy to popularize and has good benefits.

Description

technical field [0001] The invention relates to a compensable and balanced winding hysteresis tensioner for textile machinery, in particular to a hysteresis tensioner used in the production of yarns, cords, carpet threads, ropes, cloth tapes and other processes of various textile machinery. Compensable balanced winding hysteresis tensioner for passive draft winding of flexible materials. Background technique [0002] The permanent magnetic hysteresis tensioner is a magnetic energy source provided by a magnetized permanent magnet when the textile machine mechanically drafts and winds the yarn rope. Tension is generated in the process, so as to realize a device with constant tension and no chaos. The patent specification with the application number of 200520024424.8 discloses a tension roller. The magnetic energy of the air gap magnetic field generated by the permanent magnetic flux is used to act on the hysteresis ring to generate a tension moment; the multi-head screw is us...

AI Technical Summary

Problems solved by technology

[0003] 1. The original tension roller has built-in permanent magnets, and the N poles and S poles are alternately arranged at equal intervals on the circumference of a single circle, resulting in pulsating fluctuations in the winding tension moment, unbalanced tension within 360-degree circumferential angles, and affecting the microscopic quality of textiles.

[0004] 2. It is difficult to ensure the consistency of the magnetic properties of the original tension roller permanent magnet parts due to the difference in materials and processes, resulting in inconsistent tension, difficult to use and verify in large quantities, and inconvenient to manage

[0005] 3. The permanent magnet and the hysteresis ring of the original permanent magnet tension roller rotate relatively continuously and are magnetized repeatedly. After a period of use, the magnetic performance will attenuate indefinitely, so that the winding tension is insufficient or the tension between the tensioners is inconsistent, and even the tensioner is damaged. scrapped, huge loss

[0006] 4. The original tension roller is limited by the single-turn permanent magnet energy, the winding tension adjustment range is small, the angle scale of the adjustment disc has an obvious nonlinear relationship with the tension, and the application of the thickness of the yarn that can be spun is limited.
