A support rod 8 is arranged between the first electric telescopic rod 7, and a second electric telescopic rod 15 is arranged between the support rods 8. A pressure sensor is arranged on the upper side of the support rod 8. 9, and a weighing box 10 is fixed on the upper side of the pressure sensor 9, and a feed port 11 is passed through the upper side of the weighing box 10, four support rods 8 are provided, and pressure sensors 9 are provided on the four support rods 8, and the control box 40 is fixed on the front side of the pre-heating box shell 2, and the arrangement of four pressure sensors 9 on the four support rods 8 can weigh the materials in the weighing box 10 at the same time, and obtain four groups of weights, and finally take the average value to improve accuracy, and the feed hose 14 and the second discharge pipe 16 can be separated from the weighing box 10, so that the weighing box 10 can be separated from it when weighing to ensure the quality of weighing, and the control box 40 is electrically connected with the first drive motor 3, the first electric heating wire 5, the first electric telescopic rod 7, the pressure sensor 9, the second electric telescopic rod 15, the plasma light oxygen integrated machine 27, the first exhaust fan 28, the second exhaust fan 32, the second electric heating wire 35 and the second drive motor 37.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, a first discharge pipe 12 is passed through the lower side of the weighing box 10, and the first discharge pipe 12 passes through the feeding hose 14, a first support plate 13 is fixed on the outer wall of the feeding hose 14, and a second electric telescopic rod 15 is fixed on the lower side of the first support plate 13, a second discharge pipe 16 is passed through the feed port 11, and a second support plate 17 is fixed on the outer wall of the second discharge pipe 16, and at the same time, the upper side of the second discharge pipe 16 is connected to the storage box 18, a third support plate 19 is fixed on the outer wall of the storage box 18, and the first electric telescopic rod 7 is fixed on the lower side of the third support plate 19, harmful gases The filter assembly 20 includes an air supply pipe 21, an air intake cover 22, a first filter screen 23, a threaded connector 24, a second filter screen 25, a filter screen tube 26, a plasma light oxygen integrated machine 27, a first exhaust fan 28, an air supply port 29, an activated carbon box 30, a sealing cover 31 and a second exhaust fan 32.

A second electric heating wire 35 is provided in the feed pipe 34, which can ensure that the preheated material maintains its own temperature during feeding to avoid the temperature being too low and affecting the quality of later processing.

[0031] Working principle: When using the fully automatic intermittent pre-expander with bin feeding for EPO production, the pressure sensor 9 model is CYYZ11, and the external power supply is turned on. Under the action of the control box 40, the first electric telescopic rod 7, the pressure sensor 9 and the second electric telescopic rod 15 are started, and the storage box 18 on the third support plate 19 is driven to move downward with the assistance of the first electric telescopic rod 7. Finally, the second discharge pipe 16 passes through the inside of the weighing box 10. When the required material is reached in the weighing box 10, the second discharge pipe 16 moves out of the storage box. The pressure sensor 9 weighs the weighing box 10. The four sets of data after weighing are transmitted to the control box 40 with the assistance of the pressure sensor 9. The control box 40 calculates the average value. When the material in the weighing box 10 reaches the required weight, the first support plate 13 is driven to move upward with the assistance of the second electric telescopic rod 15. Finally, the first support plate 13 fits the weighing box 10. The weighed material in the weighing box 10 enters the interior of the preheating box housing 2 through the material delivery hose 14. The control box 40 starts The first electric heating wire 5, the first driving motor 3 and the first exhaust fan 28 are driven. The first driving motor 3 rotates to drive the stirring rod 4 to rotate. The stirring rod 4 rotates the first electric heating wire 5 on the stirring rod 4 to preheat the material. The harmful gas generated during preheating passes through the second filter 25 under the auxiliary action of the first exhaust fan 28 and enters the ion light oxygen integrated machine 27. After being treated by the ion light oxygen integrated machine 27, the waste gas enters the activated carbon box 30 for further treatment to ensure the quality of waste gas treatment. The preheated material enters the feed pipe 34 through the discharge port 33. Under the action of the control box 40, the second driving motor 37 is started. The second driving motor 37 rotates to drive the driving gear 36 to rotate. The driving gear 36 rotates to drive the discharging screw 38 to rotate. The discharging screw 38 rotates to discharge the preheated material for feeding, which can increase the number of later processing. The second electric heating wire 35 is set to heat and keep the material warm when discharging the material to avoid the material temperature being too low to affect the quality of later processing.
