Automatically adjusted magnetic tensioner for textile processing

Abstract

The invention relates to the technical field of textile processing equipment, and discloses an automatically adjusted magnetic tensioner for textile processing. The tensioner comprises an equipment shell, and further comprises a mounting shaft, an adjusting assembly, a rotating shaft, a damping wheel and an induction assembly, wherein the front face of the equipment shell is fixedly connected with the mounting shaft, the adjusting assembly is fixedly connected to the front face of the mounting shaft, the rotating shaft is fixedly connected to the front face of the equipment shell, and the damping wheel is movably connected to the front face of the rotating shaft. According to the automatically adjusted magnetic tensioner for textile processing, when the damping wheel rotates to a normal rotating speed, the working resistance value of a thermistor is reached, an external power source is connected with an electromagnet, the damping wheel slips to cause stall, so that a dielectric plate is reset under the action of a reset spring, and after the working voltage of a piezoresistor is reached, the current in the electromagnet is increased, so that the ferromagnetism of the electromagnet is stronger, a magnetostrictive shaft is further shortened, a wool loop is further pressed, and the damping wheel is prevented from continuously slipping.

Description

technical field [0001] The invention relates to the technical field of textile processing equipment, in particular to an automatically adjustable magnetic tensioner for textile processing. Background technique [0002] The magnetic tensioner is a tension control device that generates damping through the magnetic field conversion torque change without mechanical friction. A certain output is given to the actuator through the magnetic tensioner. The wiring method of the magnetic tensioner needs to be in accordance with the wiring diagram in the manual. Carry out threading, and then adjust the dial scale to 0 according to the anti-tension scale. At this time, the wool loop is relaxed, and the tightness of the wool loop is adjusted according to the tension used. The wool loop with a small tension is relaxed, and the wool loop with a high tension is pressed tightly [0003] During the winding process, the magnetic tensioner can give a constant tension to the wire, so as to achiev...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatically adjustable magnetic tensioner for textile processing, which has the advantage of high degree of automation and solves the problem of the simple structure of some magnetic tensioners, the size of the tension and the tightness of the wool loop. It needs to be adjusted manually, the adjustment accuracy is low, and in the working process, the residual yarn fiber will cause the damping wheel to slip, which will affect the tension adjustment effect and further affect the textile quality.
