Electromagnetic heating roller device with built-in coil

Abstract

The invention provides an electromagnetic heating roller device with a built-in coil, which comprises a roller and an electromagnetic heating coil structure component, wherein the roller is a cylindrical conductor; the electromagnetic heating coil structure component is located in the middle of the roller and is concentric with the roller, and a gap is configured between the electromagnetic heating coil structure component and the roller. The electromagnetic heating roller device has the advantages of a simple structure, convenient maintenance, low fault rate, good safety, reliability and energy-saving and environment-friendly properties.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an electromagnetic heating roller device with a built-in coil. Background technique [0002] Heating rollers are widely used in smoothing and calendering of plastic sheets, paper, leather, non-woven fabrics, decorative sheet fibers, and other industries. At present, the main heating methods of the heating roller are heat transfer oil heating, steam heating transfer, and resistance heating. The first two heating methods are heat transfer media such as heat transfer oil or steam heated outside the roller, and then transported to the roller body through medium circulation heat conduction; resistance heating It is heated and conducted by inserting the heat pipe into the roller body or the heat conduction oil in the roller. The above three heating methods all have the following disadvantages: [0003] The heat transfer medium heat transfer oil or steam will produce oil film, gre...
