[0024] As Figures 1 - 3As shown in the figure, a material screening component 4 is installed in the lower middle part of the inside of the feeding box 1, and a sieve hole adjusting component 5 is connected to the lower side of the material screening component 4. The material screening component 4 includes an upper sieve plate 401 and upper sieve holes 402, and upper sieve holes 402 are formed inside the upper sieve plate 401. The material screening component 4 further includes springs 403 and mounting plates 404. The upper sides of both sides of the upper sieve plate 401 are elastically connected to the mounting plates 404 through the springs 403, and the mounting plates 404 are bolted to the inner wall of the feeding box 1. The material screening component 4 further includes a flexible connection cover 405, and a flexible connection cover 405 is connected between the inner sides of the mounting plates 404 and the upper sieve plate 401; the mounting plates 404 on the upper side of the upper sieve plate 401 can be bolted to the inner wall of the feeding box 1. Through the upper sieve plate 401 and the upper sieve holes 402, it is convenient to screen the capsule particles entering the inside of the feeding box 1, avoid abnormal capsule particles with non-compliant sizes during the feeding process, and enable the upper sieve plate 401 to vibrate up and down under the elastic action of the springs 403 when impacted, so as to facilitate the screening of capsule particles and prevent the capsule particles from being stuck in the upper sieve holes 402.

[0025] As Figures 2 - 4 As shown in the figure, the sieve hole adjusting component 5 includes a limit frame 501, a lower sieve plate 502, lower sieve holes 503, a connecting plate 504 and a rack 505. Limit frames 501 are fixed on the front and rear sides below the upper sieve plate 401, and the limit frames 501 are in an "L" shape. The lower sieve plate 502 is slidably installed inside the limit frames 501, and the lower sieve plate 502 is slidably connected to the upper sieve plate 401. Lower sieve holes 503 are formed inside the lower sieve plate 502. A connecting plate 504 is integrally fixed to the right side of the lower sieve plate 502, and a rack 505 is fixed on the surface of the connecting plate 504.

And during this process, the rotation of the gear 507 can be driven by the micro motor 506 and the motor shaft, and then the movement of the rack 505 and the connecting plate 504 can be driven, so that the lower sieve plate 502 on one side of the connecting plate 504 slides left and right inside the limit frame 501 to adjust the position of the lower sieve holes 503 below the upper sieve holes 402, and further adjust the sieve hole size of the upper sieve holes 402 to meet different screening requirements;

[0028] During the screening process of capsule particles, the heating layer 302 is internally provided with heating wires to heat the gas entering the interior of the drying box 301. Then, the hot air inside the drying box 301 is sent into the interior of the feeding box 1 through the air supply pump and the air supply pipe 305 to dry the rubber particles therein. Then, the hot air inside the feeding box 1 can flow back into the interior of the drying box 301 through the air inlet pipe 303 and the filter screen 304 for circulating drying. Finally, the screened capsule particles are fed into the interior of the capsule filling machine through the material discharging port on the lower side of the feeding box 1, enabling the capsule filling machine to fill the capsules. In this way, the use process of this auxiliary feeding component and capsule filling machine is completed.
