Electromagnetic heating device of iron finishing roller of iron finishing machine

Abstract

The invention relates to an electromagnetic heating device of an iron finishing roller of an iron finishing machine. The electromagnetic heating device comprises an upper heating cover assembly (17) and a lower heating cover assembly (20), wherein the upper heating cover assembly and the lower heating cover assembly are in the shape of a circular arc and are symmetrically arranged at the outer side of an iron finishing roller (16); the upper heating cover assembly and the lower heating cover assembly consist of a cover casing (9), an inner clapboard (10), heating coils (12) and an outer clapboard (11); the heating coils (12) are arranged between the inner clapboard and the outer clapboard in a sinusoidal waveform curve; the heating coils can be externally connected with an electromagnetic induction heating controller in an electric cabinet; and an end cover is provided with a sensor for measuring the dynamic temperature of the iron finishing roller, the signal lines of the sensor are connected with a digital display screen and a power adjusting switch in the electric cabinet, and the temperature can be adjusted and controlled by adjusting the amount and the on / off of the current. The invention heats the iron finishing roller by the electromagnetic induction method from the outside, and the heat is not conducted by other materials in the whole heating process, thereby ensuring high heating speed and high thermal efficiency. Meanwhile, the invention has the advantages of good thermal insulation effect, high heat utilization efficiency, less failures and long service life.

Description

technical field [0001] The invention relates to fabric finishing equipment in textile machinery, in particular to an electromagnetic heating and heat-preserving device for ironing rollers of ironing machines. Background technique [0002] The ironing roller is the main energy-consuming component in the ironing machine. In order to improve the utilization rate of heat energy, the ironing machine adopts one roller body, uses both sides, and performs secondary ironing on the fabric. At present, the ironing machine heats the ironing roller by heating from the inside of the ironing roller. In theory, the heat generated from the inside of the ironing roller can be attracted and utilized by the roller body. However, it is by no means easy to introduce the power supply into the rotating ironing roller, generate heat through the heating element, and overcome the influence of centrifugal force on the heating element. Conductive and heat-generating components with complex structure,...

Problems solved by technology

However, it is not easy to introduce power into the rotating ironing roller, generate heat through the heating element, and overcome the influence of centrifugal force on the heating element

Conduction and heating devices with complex structures are placed in a closed high-temperature environment for a long time, with low service life, high failure rate, and difficult maintenance

In addition, in the electric heating device inside the ironing roller, the heat insulation effect of the insulating material and the heat dissipation performance of the roller body are often beyond people's expectations, so that the actual heating effect is not ideal. The main manifestations are: long preheating time, high temperature Slow speed, high heat loss
