Detailed Description

Referring to fig. 1 to 4, the automatic collecting and cleaning mechanism for leaked powder during capsule filling applied to a capsule filling machine comprises a metering disc 2 (made of impermeable steel material), a metering disc seat 3 (made of copper material), a base 4, a metering disc transmission shaft 10 (including a metering disc flange), a sealing ring 5 (made of copper) is arranged at the inner periphery of the measuring disc seat 3 and below the measuring disc 2, and the upper plane of the sealing ring 5 (corresponding to the lower plane of the metering disc) has a downward slope (i.e. a downhill structure) to facilitate the (free) downward sliding of the leaked powder, a powder scraping sheet 11 is arranged on the metering disc transmission shaft 10, the powder scraping sheet 11 is positioned at the bottom of the metering disc seat 3 between the sealing ring and the metering disc transmission shaft, a powder suction port 12 (which can be one and is connected with an external powder suction device) is arranged at the inner groove 32 at the bottom of the metering disc seat 3.

The metering disc seat 3 may also be called a sealing ring seat, and has an outer peripheral sealing ring 31, a bottom inner groove 32 (for absorbing and discharging the finally collected leaked powder), and a bottom 33 (the upper surface of the bottom is in a downhill structure from the outer peripheral sealing ring to the bottom inner groove, which is beneficial to scraping the leaked powder on the bottom into the bottom inner groove), the metering disc transmission shaft 10 is located in the bottom inner groove, and the metering disc is installed on the metering disc transmission shaft and has a gap with the sealing ring and the metering disc seat. The outer diameter of the sealing ring is equivalent to the inner diameter of the sealing ring at the periphery of the metering disc seat, and the inner diameter of the sealing ring is larger than the inner groove in the bottom of the metering disc seat.

The powder scraping sheet 11 is in a 7-shaped (or T-shaped) structure, one transverse edge of the powder scraping sheet is positioned above the bottom of the metering disc seat 3 (slightly higher than the bottom of the metering disc seat), and one vertical edge of the powder scraping sheet is positioned in an inner groove 32 in the bottom of the metering disc seat. A plurality of powder suction holes 9 (the number and the aperture of which are equivalent to capsule body holes on a lower die which is provided with capsule bodies and passes through the holes) are arranged on the metering disc seat 3 and below the powder discharging station of the metering disc 2, and the powder suction holes 9 are communicated with a channel of a powder suction port 12. A plurality of clearance gauge mouth baffles 6 (movably inserted or taken as shown in fig. 3) are embedded on the outer periphery sealing ring 31 of the metering disc seat 3, so that the clearance between the metering disc and the sealing ring can be finely adjusted by taking the clearance gauge mouth baffles and inserting a clearance gauge, and the clearance gauge mouth baffles are embedded after the fine adjustment is finished.
