[0018] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0019] In the present invention, by introducing electromagnetic roller heating technology, the whole set of equipment is optimized and upgraded, which is specifically reflected in the composition and functions of the following parts: Pole roll unwinding mechanism: This mechanism is responsible for evenly unwinding the pole roll material to be baked from the reel and sending it into the baking chamber. The application of electromagnetic roller heating technology enables the pole roll in the unwinding process to quickly obtain the required preheating temperature, preparing for subsequent efficient baking; Electromagnetic heating roller transmission system: This system is the core part of the present invention, which consists of an electromagnetic roller, a servo motor, a reducer, a synchronous belt, etc. The electromagnetic roller is used as a heating element, and its internal non-contact electromagnetic induction mechanism can quickly generate heat to achieve uniform and efficient heating of the pole rolls passing by. The servo motor and the reducer work together to ensure that the electromagnetic roller rotates at a constant speed, thereby ensuring the consistency of the baking effect; Hot air circulation system: Assists electromagnetic roller heating and further enhances the heat transfer efficiency in the baking chamber through hot air circulation. The hot air can be evenly distributed in the baking chamber, so that each part of the pole roll is heated more evenly.

Pole coil cooling mechanism: After baking, the pole coil needs to be cooled down quickly through the cooling mechanism in order to solidify the baking effect and carry out subsequent processing. The electromagnetic roller heating method heats up quickly and cools down relatively quickly, which helps to improve the operating efficiency of the entire production line; Pole roll slitting and winding mechanism: The pole roll that has been baked and cooled will be transferred to the slitting and winding mechanism, cut and rewound according to demand. The electromagnetic roller heating ensures the consistency and quality of the pole roll, making the slitting and winding process smoother and ultimately producing high-quality products.
