High frequency source electric heating heat setting roller

Abstract

The invention relates to the field of weaving machinery and in particular relates to a thermal setting roller for post-treatment of chemical fiber short fibers. A high-frequency source electric heating thermal setting roller comprising a roller cylinder, a fixing sleeve, a heating coil, a spline shaft, a thermodetector and an inner end cover, wherein one end of the roller cylinder is provided with an external end cover and the other end of the roller cylinder is fixed on the fixing sleeve; the fixing sleeve is fixed on the rack; the spline shaft is mounted in the axis of the roller cylinder; one end of the spline shaft is fixedly connected with an external hollow driving rotating shaft; the other end of the spline shaft is fixedly connected with the roller cylinder and axially fixed by the inner end cover; the heating coil is covered with the roller cylinder; an axial temperature measuring hole is formed in the side wall of the roller cylinder; and the thermaldetector is placed in the temperature measuring hole. High-frequency source heating technology is employed for the high-frequency source electric heating thermal setting roller, so heat can be evenly transmitted and small surface temperature difference is achieved; heating temperature can be controlled when heat is transmitted to a temperature control mechanism via a guide line, so heating temperature can be steplessly adjusted; high temperature adjusting precision and safety and reliability can be achieved; and great technology adaptability can be achieved.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a heat setting roller for post-treatment of short chemical fibers. Background technique [0002] Tension heat setting machine is the key equipment in the chemical fiber short fiber post-processing production line. Its function is to dry the fiber that has been drawn to a certain fineness under a certain tension, raise the temperature and set the shape, so as to improve the fiber strength and stretch. The degree of reduction is reduced, and the product fiber has good dimensional stability. The heating and setting of the fiber is realized by contacting the heat transfer with the surface of the heat setting roller, and the surface of the heat setting roller is required to have a higher temperature. [0003] In order to realize the heat of fibers at high temperature, the heat setting rollers on the existing tension heat setting machine generally adopt the following three ways to prov...

Problems solved by technology

Although this method can avoid the use of steam boiler equipment during operation and only provide heat source through the heater, it is difficult to control the heating temperature of the heater in time. When the heating temperature of the heater is too high, if no measures are taken, it is easy to Heat setting rollers cause damage, affecting safe production

[0006] The third method is to use heat conduction oil to heat the roller body, but due to the difficulty of sealing, easy leakage, poor safety, and difficult maintenance of this solution, it is rarely used at present.
