[0002] The coil that balances the temperature difference between the two ends of the electromagnetic heating roller is an induction coil. The induction coil is one of the core components of the electromagnetic heating roller, generating heat through the principle of electromagnetic induction. When an alternating current passes through the induction coil, an alternating magnetic field is generated inside the roller, which in turn generates eddy currents on the roller surface. Due to the resistive properties of the roller material, the eddy currents generate heat, thus achieving the heating effect.

[0003] However, the existing coil structure for balancing the temperature difference at both ends of the electromagnetic heating roller has the following disadvantages:

[0004] (1) The existing coil structure for balancing the temperature difference at both ends of the electromagnetic heating roller has a weak function of uniform heating. When in use, the temperature difference at both ends of the existing device may be caused by uneven distribution of the coil magnetic field, differences in thermal conduction of the roller material, or heat dissipation.

[0005] (2) The existing coil structure for balancing the temperature difference at both ends of the electromagnetic heating roller has a weak maintenance function. When using the existing device, the coil may age and cause poor heating effect. Utility Model Content
