A nano-carbon fiber electromagnetic induction heating roller device

Abstract

The invention discloses a carbon nanofiber electromagnetic induction heating roller device, which comprises a roller body. A center shaft is arranged in the roller body; an electromagnetic induction coil is wound at the outer side of the center shaft; the electromagnetic induction coil is connected with an electromagnetic heating controller outside the roller body; the roller body comprises a barrel and metal end covers respectively arranged at both ends of the barrel; and the barrel is made of a carbon nanofiber composite. The carbon nanofiber electromagnetic induction heating roller device disclosed by the invention has the beneficial effects that the barrel made of the carbon nanofiber composite has the characteristics of high specific strength, high conductivity, high temperature resistance, low density compact structure and the like; compared with a barrel made of iron, the barrel made of the carbon nanofiber composite is reduced by 70 percent in total body mass; and the inertia is also reduced by about 70 percent when the carbon nanofiber roller runs at a high speed, so that the roller is accurately guaranteed in concentricity and runout during a running process. The barrel made of the carbon nanofiber composite is good in heat transfer property and heat stability.

Description

technical field [0001] The invention relates to a heating roller, in particular to an electromagnetic induction heating roller device. Background technique [0002] Heating rollers are widely used in the flattening and calendering of laser film, paper, non-woven fabrics, plates, fibers, rubber, plastics and other industries. At present, the mainstream heating method of heating rollers is the heating and conduction method of heat transfer oil, but some domestic enterprises have started The electromagnetic induction heating roller is used to replace the thermal oil heating roller. The electromagnetic induction heating roller will quickly replace the traditional thermal oil heating roller due to its advantages of electromagnetic heating, energy saving, no pollution, more uniform temperature, and convenient maintenance. [0003] At present, although the electromagnetic induction heating roller has made breakthroughs in terms of energy saving, no pollution, more uniform temperatu...

AI Technical Summary

Problems solved by technology

[0005] 1. The material of the electromagnetic heating roller device is a metal substrate, and the overall mass is relatively large. In the case of high-speed operation of the equipment, the inertia is very large, so it is difficult to realize the concentricity and beating degree of the electromagnetic heating roller under high-speed operation accuracy requirements;

[0006] 2. The electromagnetic heating roller made of metal has a large coefficient of thermal expansion and a decrease in strength at high temperature, and is prone to thermal deformation, which affects the accuracy of the equipment and hinders the production of high-performance products.
