Benefits of technology
This patented technology uses an electric coil wrapped around one side of a rotor shaped metal plate called a drum's wheel (roller). When powered by this electrical device, it create magnetic fields inside its housing through induction. These induced currents flow within the steel plates along their entire length. By applying these AC signals onto the rolling band itself, there can be controlled temperature without burning up any parts like traditional methods for controlling the temperature of certain materials used during production processes.
Problems solved by technology
The technical problem addressed in this patented text relates to improving the heat transfer from an electrically conductive material (rolling belts) during thermal treatment processes such as plastification process. Current methods have limitations with regard to achieving even distribution on the surface being treated due to poor contact between the materials involved. This results in unevenly distributed temperatures that require longer periods of energy input compared to other techniques like inductively coupled resistance welding. Therefore, improved ways are needed to improve the heat transmission without compromising its effectiveness at controllable levels while maintaining good consistency across different types of materials undergoing manufacturing operations.

Embodiment Construction
[0016] Please refer to figure 1 shown, figure 1 It is an example of a set of rolling belts. The object to be processed can be directly placed on the worktable, and the surface of the rolling belt that generates heat can be used to heat the object to be processed. The high-frequency electric heating rolling belt of the present invention is composed of a rolling belt body 10, two rollers 20 and a heating device. The rolling belt body 10 is wound on two rollers 20, and the outer surface of the rolling belt body 10 is in contact with the object to be processed, so that the object to be processed is heated. When the roller 20 rolls, due to the friction force between the roller 20 and the rolling belt body 10 , the rolling belt body 10 is driven by the roller 20 to move. The rolling belt body 10 has conductivity, and the heating device is connected to a high-frequency AC power supply.
[0017] The heating device includes at least two conductive components 30, 40 connected to differe

A high-frequency electric heating rolling belt comprising at least a roller (20), a rolling belt main body (10), and at least a heating apparatus. The rolling belt main body (10) is provided with electrical conductivity. The roller (20) drives the rolling belt main body (10) into motion. The outer surface of the rolling belt main body (10) is in contact with an object-to-be-processed. The heating apparatus is connected to an external high-frequency alternating current power source. The heating apparatus comprises two electrically conductive components (30 and 40). One electrically conductive component (30) is in frictional contact with one side of the rolling belt main body (10). The other electrically conductive component (4) is in frictional contact with the other side of the rolling belt main body (10). The two electrically conductive components respectively are connected to different electrodes of the external high-frequency alternating current power source. A high-frequency current is lead to aggregate on the outer surface of the rolling main body (10) by actions of the two electrically conductive components (30 and 40), thus the high-frequency alternating current is allowed to flow on a surface of the rolling belt main body (10), while rapid warming and heating of the surface of the rolling belt main body (10) is allowed due to the presence of impedance, thus allowing for heat treatment of the object-to-be-processed.
