[0050] Working process:

[0051] When this solution is implemented, according to production requirements, corresponding types of transfer tubes 8 are installed in the transfer holes 301 of multiple core bodies 3. When the core body 3 is in the first working position, the upper end of the transfer tube 8 is connected to the feed hole 104, and the material enters the transfer tube 8 under the vibration of the vibrator (at this time, the limit plate 304 limits the guide rod 303, and the end of the strip through hole 103 away from the discharge hole 105 limits the slide column 307), and a force is applied to the core body 3 to move the core body 3 toward the discharge hole 105, and the compression spring 6 further compresses When the core 3 is in the second working position, the transfer tube 8 is aligned with the discharge hole 105 (the end of the strip-shaped through hole 103 near the discharge hole 105 limits the sliding column 307). Under the vibration of the vibrator, the material in the transfer tube 8 flows into the reactor through the discharge hole and the discharge tube 7. The force applied to the core 3 is released. Under the elastic force of the compression spring 6, the core 3 is reset to the first working position. During the movement of the core 3, the transfer tube 8 has a third position, so that the upper end surface of the transfer tube 8 is sealed. The volume of a fixed volume powdered material multiplied by the density is the weight of the material.

[0052] Compared with the traditional weighing feeding, the fixed volume of powdered material can be transferred by moving the core 3, which improves the work efficiency. The vibration of the vibrator prevents the powdered material from sticking to the side wall, thereby ensuring the accuracy of the material feeding.
