The heat sensitive paper is placed on the placing rack. When the heat sensitive paper is exported, the rotating motor rotates to drive the rolling rod to rotate, the rolling rod rotates to drive the flattening roller to rotate, and the heat sensitive paper is flattened. Two pressure springs can adjust the export according to the thickness of the heat sensitive paper. The work is completed by the export plate. However, in the scheme, the feeding rod is directly controlled by the motor. This direct motor driving method has relatively low control accuracy and cannot achieve very accurate position control and speed control. In some high-precision feeding scenarios, the material may not be accurately placed at the specified position, resulting in substandard feeding accuracy. Moreover, the feeding device cannot accurately control the conveying speed of the motor. Since the rotating speed cannot be accurately controlled, the motor may run at unnecessary high speed or frequently switch between different rotating speeds, thereby increasing energy consumption. Therefore, the heat sensitive paper processing automatic feeding device needs to improve the above problems. UTILITY MODEL CONTENTS
