Embodiment 1

[0035] attached figure 2 and image 3 As an embodiment of the present invention, it is an electrically heated rubber heating roller, which at least includes a heating roller outer layer 2 and a heating roller inner layer 4, and is provided with heating roller supports and transmissions for supporting the heating roller at both ends of the heating roller. The shaft 1 is provided with an electric heating tube 6 for heating the heating roller inside the heating roller; there is a heating roller interlayer 5 between the heating roller outer layer 2 and the heating roller inner layer 4, thereby forming a sandwich structure. The heating roller interlayer 5 is a closed independent cavity, and the heat-conducting liquid medium in the interlayer of the independent cavity makes the temperature of the outer surface of the heating roller uniform in a self-circulating flow state. The heating roller interlayer 5 is in the form of a continuous full cylinder. The heating roller interlayer ...

Embodiment 2

[0038] attached Figure 4 and Figure 5As another embodiment of the present invention, it is a heating roller of a printing machine heated by oil or steam. The heating roller at least includes a heating roller outer layer 2 and a heating roller inner layer 4. The heating roller support of the roller, the transmission shaft 1, the inner layer 4 of the heating roller is filled with heating oil or steam 7, and there is a heating roller interlayer 5 between the outer layer 2 of the heating roller and the inner layer 4 of the heating roller, thus forming a kind of interlayer structure. The heat-conducting liquid medium 3 is filled in the heating roller interlayer 5, and the heat-conducting liquid medium 3 is potassium-sodium molten metal, pure water, ethanol, and the outer layer 2 of the heating roller passes through the potassium-sodium molten metal and pure water in the heating roller interlayer 5. , Ethanol substances, heated by heat conduction. The heating roller interlayer ...

Embodiment 3

[0041] attached Figure 6 and Figure 7 Another embodiment of the present invention is a plastic film heating roller, which is an electromagnetically heated single-arm heating roller. The heating roller at least includes an outer layer 2 of a heating roller and an inner layer 4 of a heating roller. The heating roller support and transmission shaft 1 supporting the heating roller are provided with an electromagnetic heating device 11 for heating the heating roller inside the heating roller, and there is a heating roller interlayer 5 between the heating roller outer layer 2 and the heating roller inner layer 4, A sandwich structure is thus formed. The heat-conducting liquid medium 3 is filled in the heating roller interlayer 5. The heat-conducting liquid medium 3 is Sanjie HD synthetic heat-conducting oil produced by Changzhou Hongyuan Sanjie Chemical Co., Ltd. Heat conduction oil is heated by heat conduction. The heating roller interlayer 5 is a non-continuous annular cross-...

Abstract

The invention discloses a heating roller heating method and a heating roller. The heating roller is heated in an oil, steam, electric or electromagnetic heating manner, and is characterized in that the heating roller has an interlayer structure, a thermally-conductive liquid medium is filled in the interlayer of the heating roller for homogenizing the temperature of the heating roller; and the outer surface of the heating roller is heated in a heat conduction manner through the thermally-conductive liquid medium in the interlayer of the heating roller. The heating roller structure comprises a heating roller with the interface structure, and the thermally-conductive liquid medium in the interface of the heating roller for homogenizing the temperature of the heating roller. The thermally-conductive liquid medium can be heat conducting oil, molten metal such as potassium and sodium, pure water, ethanol-like substance, etc.

Description

technical field [0001] The invention relates to a heating method and structure of a heating roller, in particular to a heating method and a heating roller used in rubber, plastic, printing and chemical fiber industries. Mainly used for heating rollers in rubber, plastic, printing and chemical fiber industries. Background technique [0002] Heating processed products by means of rolling with heating rollers is a commonly used method in rubber, plastics, printing, and chemical fiber industries. Especially for the heating of sheet roll products, it is more suitable to heat the processed products by means of heating roller heating. [0003] The heating methods of the heating roller currently used include steam heating, oil heating and electric heating. Among them, steam heating is sent into the heating roller through the superheated steam of the boiler slurry to heat the heating roller. This heating method has long pipelines and is prone to leakage and corrosion, so it has bee...
