Before using the equipment, the power supply of the power motor is turned on, the raw material chip is placed inside the feeding mechanism, and finally the thermistor is placed inside the feeding box. The thermistor is affected by the inclination angle of the feeding box and enters the correction tube. At this time, the thermistor will present a V state with the main body downward or the main body upward in Figure 5. When the thermistor presents a V state, since the volume of the main body is larger than that of the lead, the main body directly passes through the correction groove along the inner wall of the correction tube and hits the side wall of the material blocking plate. At this time, due to the smaller volume of the lead part, it will directly pass through the correction groove and fall on the surface of the material blocking slide plate.
