A storage cavity 13, a guide cavity 14, and a discharge cavity 15 that are connected to each other are sequentially arranged inside the material cylinder 1 from top to bottom. The storage cavity 13 is connected to the feed port 11, and the bottom of the discharge cavity 15 is connected to the discharge port 12. The guide cavity 14 is conical to facilitate guiding of materials.

[0025] Specifically, as Figures 1 - 2As shown in the figure, the servo discharging module is connected to the material cylinder 1 to control the discharging amount of the discharging port 12 at the bottom of the material cylinder 1. The servo discharging module includes: a servo motor 21 and a transmission rod 22. The servo motor 21 is arranged at the top of the material cylinder 1, and the output end of the servo motor 21 penetrates through the top of the material cylinder 1 and inserts into the interior of the material cylinder 1; the top end of the transmission rod 22 is connected to the output end of the servo motor 21, the bottom end of the transmission rod 22 inserts into the discharging cavity 15, and a spiral groove 221 is arranged at the bottom of the transmission rod 22. By operating the servo motor 21, the transmission rod 22 can be driven to rotate, so that the material is discharged from the discharging port 12 through the spiral groove 221. Based on the number of turns of the transmission rod 12 rotated by the servo motor 21, the discharging amount of the powder material can be quantitatively controlled.

[0026] Further, as Figures 1 - 2 shown, the servo discharging module further includes: a flexible connector 23, and the flexible connector 23 connects the output end of the servo motor 21 and the top end of the transmission rod 22, and has high angle compensation.

[0027] Further, as Figures 1 - 2 shown, the servo discharging module further includes: a scraper, the scraper is fixed on the transmission rod 22, and the scraper is attached to the bottom inner wall of the storage cavity 13 and the inner wall of the material guiding cavity 14. The scraper consists of a connecting section 241, a first scraping section 242 and a second scraping section 243. The connecting section 241, the first scraping section 242 and the second scraping section 243 are connected end to end in sequence. The connecting section 241 is fixed to the transmission rod 22, the first scraping section 242 is attached to the bottom inner wall of the storage cavity 13, and the second scraping section 243 is attached to the inner wall of the material guiding cavity 14.

The material cover can also be connected to an external driving mechanism to achieve the purpose of automatic opening and closing.

[0031] Working principle: During use, the material enters the material cylinder 1 through the feed inlet 11. By controlling the number of rotations of the transmission rod 22 driven by the servo motor 21, the purpose of quantitatively discharging the powder material from the discharge outlet 12 is achieved.

When multiple powder materials need to be quantitatively mixed, multiple servo discharging mechanisms are adopted, and each discharging mechanism controls one kind of powder material, achieving automatic quantitative mixing ratio of the powder materials.
