[0021] like Figure 1 and Figure 2 As shown, the utility model also discloses the following more optimized specific structures:

[0022] In order to facilitate efficient heating of slot discs of different heights (not shown in the figure) and achieve better automatic control functions, the efficient heating system for heating the slot disc of the electromagnetic brake also includes a height detection bracket 8, a height detection sensor 10, a generator bracket 4, a height adjustment bracket 5, a height adjustment drive motor 6 and a controller (not shown in the figure), the height detection bracket 8 is installed on the frame 1 and is located above the conveyor belt 2, the height detection sensor 10 is installed on the height detection bracket 8 and is used to detect the height of the slot disc placed on the conveyor belt 2, the electromagnetic generator 3 is installed on the generator bracket 4, the height adjustment bracket 5 is installed on the frame 1 and is located next to the conveyor belt 2, the height adjustment drive motor 6 is installed on the height adjustment bracket 5, the rotating shaft of the height adjustment drive motor 6 is connected to the generator bracket 4 through a height adjustment transmission device (located in the height adjustment bracket 5, not visible in the figure) and can drive the generator bracket 4 to move up and down, the signal output end of the height detection sensor 10 is connected to the signal input end of the controller, and the control input end of the height adjustment drive motor 6 and the control input end of the conveying motor 13 are respectively connected to the control output end of the controller.

[0023] In order to better meet the needs of height detection of slot plates at different heights, the height detection sensor 10 is a displacement sensor and is installed on the lifting cylinder 9. The lifting cylinder 9 is installed on the height detection bracket 8. The control input end of the lifting cylinder 9 is correspondingly connected to the control output end of the controller.

[0024] In order to realize the reliable transmission function of the height adjustment transmission device, the height adjustment transmission device includes a screw and a nut (both are not visible in the figure), the vertical screw is installed on the height adjustment bracket 5 through a bearing and is connected to the rotating shaft of the height adjustment drive motor 6, the nut is sleeved on the screw, the nut is connected to the generator bracket 4, and a vertical guide rod (not visible in the figure) is installed on the height adjustment bracket 5, and the guide rod passes through the corresponding through hole on the generator bracket 4. The above-mentioned height adjustment transmission device is a conventional screw transmission structure in the prior art, so it is not specifically shown in the figure.

[0025] In order to achieve a more reliable height adjustment function, the height adjustment drive motor 6 is a servo motor.

[0026] For ease of application, there are two conveyor belts 2 that are parallel to each other and driven by the same conveying motor 13. Correspondingly, there are two driving pulleys 14 and two driven pulleys 12, but only one transmission gear set. The two driving pulleys 14 are connected by a transmission connecting rod to achieve synchronous movement of the two conveyor belts 2.

[0027] In order to achieve a more comprehensive and faster heating effect, the electromagnetic generator 3 is an induction cooker and is multiple and arranged in sequence in the lateral movement direction of the conveyor belt 2. Two adjacent electromagnetic generators 3 are arranged laterally staggered at right angles to the lateral movement direction of the conveyor belt 2, so as to better cover the area where the larger trough plate is located.

After turning on the conveying motor 13, the conveyor belt 2 starts to move, driving the storage plate and the slot plate to move in the direction close to the electromagnetic generator 3. First, it must pass under the height detection sensor 10. The height detection sensor 10 detects the actual height of the slot plate and sends the information to the controller. The controller controls the height adjustment drive motor 6 to move the generator bracket 4 up and down to the appropriate position according to the height information. This position keeps the vertical distance between the electromagnetic generator 3 and the slot plate at a fixed height to ensure consistent heating efficiency; in this process, if the height of the slot plate is too high or too low and cannot be detected well, the vertical position of the height detection sensor 10 can be changed by controlling the lifting cylinder 9. Then, multiple electromagnetic generators 3 are turned on, and the trough plate passes under the multiple electromagnetic generators 3 in turn and is quickly heated (for example, heated to 70°C-100°C). By controlling the speed of the conveyor belt 2 and the power of the electromagnetic generator 3, the heating speed can be controlled, and ultimately the purpose of efficient heating is achieved.
