[0039] The working principle of this precision leveling and feeding machine is as follows:

[0040] Start the servo motor.

[0041] During this working process, the detection wheel 56 of the discharging mechanism 5 rotates in cooperation with the discharging roller 53. An inner Mikron encoder 7 is installed on the rotating shaft of the detection wheel 56. The inner Mikron encoder 7 is used to measure the rotation angle and speed of the detection wheel 56, thereby indirectly measuring the feeding length of the metal sheet and feeding back to the servo motor. The servo motor controls the feeding roller assembly 43 to feed precisely, making up for less feeding and reducing more feeding to ensure the length accuracy of the product.

The magnetic powder torque limiter 6 is used to control the torque and prevent overload, ensuring that the tension roller assembly 54 will not damage the material. The torque motor 55 can protect and reduce the load of the magnetic powder torque limiter 6 and improve the stability.
