[0004] After searching, it was found that the feeding structure of the device could not achieve quantitative feeding when in use, which resulted in the inability to control the amount of powder fed into the device, which would not only cause too much powder to enter the reactor and cause waste, but would also affect the mixing of materials in the resin reactor; furthermore, the device's method of using a conveying pipe for transportation was not effective. Due to its volume, powder was prone to accumulation during batch transportation, and the device's conveying pipeline did not have a design for moving powder, which resulted in accumulation at the beginning of the powder transportation. In this way, the staff needed to perform internal maintenance, which not only wasted processing time but also delayed the efficiency of the resin reaction.

[0032] The working principle is as follows. Connect the other end of the conveying pipe 16 to the resin reaction kettle. The powder feeding mechanism is higher than the resin reaction kettle. During use, by setting the quantitative feeding assembly, a fixed amount of powder is poured into the blanking hopper 11. The spiral conveying cone 18 is used to convey the powder. By rotating the turntable 24 on the support 19 to adjust the cooperation of the connecting rod 22 and the blocking plate 21, the blocking plate 21 blocks and releases the powder in the blanking hopper 11, so that the powder can be quantitatively conveyed, thereby helping the materials in the reaction kettle to be quantitatively mixed and avoiding material waste; by setting the material dialing and conveying structure, when the powder enters the conveying pipe 16, the powder is dialed by the rotation of the dialing fan 28 and its shape. This can not only prevent the powder from accumulating at the pipe orifice of the conveying pipe 16, but also speed up the processing time. At the same time, the timely powder conveying speeds up the efficiency of the resin reaction.

A U-shaped column is fixedly arranged at the center position of the bottom of the plugging plate 21. The plugging plate 21 is rotatably connected to the other end of the connecting rod 22 through the U-shaped column; As Figure 1 、 Figure 3 and Figure 4 shown in the figure, the plugging plate 21 is located directly below the bottom end of the blanking hopper 11. The plugging plate 21 is a square structure. A notch for blanking is provided at one end of the top of the plugging plate 21. A hinge seat 26 is fixedly arranged at the other end of the top of the plugging plate 21. There are two hinge seats 26.

At this time, the powder material reaches the bottom of the blanking hopper 11 through the conveying of the spiral conveying cone 18. The powder material slides through the notch of the plugging plate 21 into the feeding and conveying structure. At this time, rotating the rotating handle 23 in the reverse direction can achieve reset.
