Natural luster finishing machine roller for electromagnetic and resistance heating by using power current

Abstract

The invention relates to a component used in textile machinery, in particular a natural luster finishing machine roller which comprises a roller body 21, a heating device and a rotary hook-up device, wherein the heating device comprises coils 7, a core barrel 22, a heat insulated pipe 6, a capacitor resistor 10, the core barrel 22, the heat insulated pipe 6 and the capacitor resistor 10 are sequentially arranged at the inner side of the roller body 21; the coil 7 formed by winding a rope-shaped heater is arranged in a groove of the core barrel 22; the starting end wire 8 of each group of coils 7 is connected with one live wire of a three-phase AC power supply on a carbon brush 16, the tail end wire 9 thereof is connected with a capacitor 10 in series and then connected with a shared neutral wire of the three-phase AC power supply on the carbon brush 16, and thus a star-shaped connection circuit combining resistor, inductance and capacitor is formed. By using the principle that power current can generate current while flowing through resistance wires and generate magnetic fields while flowing through magnetic fields to make magnetic conductors generate heat because of inductance, the natural luster finishing machine roller has the advantages of dual effects of electromagnetic and resistance heat, high heating speed, high energy utilization rate and few device failures.

Description

technical field [0001] The invention relates to fabric finishing equipment in textile machinery, in particular to an ironing roller of an ironing machine which utilizes power frequency current for electromagnetic and resistance heating. Background technique [0002] Ironing machines and combined ironing and shearing machines are the main energy-consuming equipment in the finishing equipment of textile machinery, and their ironing rollers are the core components and main energy-consuming components of these two models. Most of the present ironing rollers are conventionally heated by electric heating rods, and more than twenty electric heating rods are evenly inserted in the inside of the roller body, and the installed power is very large. And what electric heating rod adopts is in the stainless steel pipe, loads on the very fine resistance alloy wire of diameter and the magnesium powder of insulation and heat insulation and other materials to make. When the heat generated by...

Problems solved by technology

In addition, the slender resistance alloy wire in the electric heating rod is under high temperature and centrifugal force for a long time, so it is very easy to be damaged; in addition, there are a large number of electric heating rods, so the failure rate is very high, and it is often necessary to stop production for maintenance, which affects the use efficiency of the equipment
