Roller heating mechanism

Abstract

The invention relates to a roller heating mechanism which belongs to the technical field of heating devices. The roller heating mechanism comprises an iron heating roller body and a heat energy supply device for supplying heat energy to the heating roller body. The roller heating mechanism is characterized in that the heat energy supply device comprises a bracket, a plurality of tile boards and electromagnetic coils with the quantity same as that of the tile boards, wherein the tile boards are inserted and embedded on the bracket and correspond to lateral faces of one side of the length direction of the heating roller body, and the electromagnetic coils are in contact with the sides of the tile boards, back to the heating roller body. The roller heating mechanism has the advantages: because the electromagnetic coils are used, tedious preheating time when the heating roller body is started is avoided, waiting cooling when the heating roller body stops working is also unnecessary, and therefore, the aim of saving energy is achieved, and a heating effect of a heated product can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of heating devices, and in particular relates to a roller heating mechanism. Background technique [0002] Heating rollers are widely used in the production of light industrial products, textile products and even chemical and pharmaceutical products. Taking textile products as an example, heating rollers are widely used in printing and dyeing, finishing, printing, embossing, spraying, brushing, brushing, combing, ironing and Heating rollers are required in the blowing process of plush fabrics. The heating methods of the heating roller in the prior art mainly include the following three types: one is to use steam for heating; the other is to use oil for heating; the third is to use electric heating wire for heating. As far as steam heating and oil heating are concerned, the heat energy is provided by separately equipped steam furnace and heating oil furnace. The disadvantage is that it is difficult to ensure...

Problems solved by technology

As far as steam heating and oil heating are concerned, the heat energy is provided by separately equipped steam furnace and heating oil furnace. The disadvantage is that it is difficult to ensure the uniformity of the surface temperature of the heating roller and the temperature is difficult to control. The heating cost is high and uneconomical.

It is also difficult to ensure the uniformity of temperature by electric heating wire heating, and it needs to be preheated for a long enough time when it is started, and it needs a long cooling time when the heating is finished, so in order to avoid wasting energy, before stopping electric heating, it is often still It is necessary to keep the heating roller working, and then stop the heating roller after the heating roller is cooled. However, because the electric heating is stopped, the temperature of the heating roller decreases gradually, which affects the heating effect of the product to a certain extent.

As a result, there is an unbalanced contradiction between saving energy and ensuring product quality.
