a powder sieving device comprises a power mechanism, a powder collecting box and two sieving plates.
The middle of the medicine powder collecting box is divided into two areas through a vertical partition plate, one screen disc corresponds to one area, and the screen disc is arranged in a sliding way along the long shaft of the medicine powder collecting box;
The power mechanism comprises a motor, a main gear and two power pieces symmetrically arranged relative to the main gear, each power piece comprises a pinion, a rotating rod and a sliding block, the motor is arranged on the supporting frame, an output shaft at the bottom of the motor is connected with the main gear, the top of the pinion is rotationally connected with the supporting frame, the main gear is meshed with the pinion, the sliding block is slidingly arranged on the supporting frame, the sliding direction of the sliding block is parallel to the long shaft of the medicine powder collecting box, two ends of the rotating rod are respectively rotationally connected with the bottom surface of the pinion and the top surface of the sliding block, and the bottom surface of the sliding block is connected with a corresponding sieve tray through a connecting plate.
Further, the support frame includes the diaphragm and locates two risers of its bottom, is equipped with the deflector between two risers, is equipped with the spout that runs through its own in the middle of the deflector, and slider sliding fit is in the spout.
Further, the longitudinal section of the sliding block is I-shaped.
Further, two wheels are respectively arranged at two ends of the sieve tray, a strip-shaped groove is arranged at the top of the side wall of the medicine powder collecting box, and the wheels are arranged in the corresponding strip-shaped grooves.
Further, two ends of the screen disc are respectively provided with a handle, and the handles are positioned between the two wheels.
Further, the connecting plate is connected with the end part of the screen disc through a plurality of screws.
The utility model has the beneficial effects that: the main gear is driven by the motor, the auxiliary gear is further driven, and when the auxiliary gear rotates, the rotating rod can promote the sliding block to reciprocate linearly, so that the sieve tray reciprocates on the medicine powder collecting box, and the medicine powder can be sieved rapidly and efficiently. The screening task of the two screening discs can be realized by one power source of the motor; two different medicinal powders can be screened at the same time, so that the screening rate is improved.

Detailed Description
As shown in fig. 1, the present embodiment provides a powder screening device comprising a power mechanism, a powder collecting box 2 and two screening discs 3.
Specifically, the middle of the powder collecting box 2 is divided into two areas through a vertical partition plate 21, the screen disc 3 is supported at the top of the powder collecting box 2, the two screen discs 3 are symmetrically arranged about the short axis of the powder collecting box 2, one screen disc 3 corresponds to one area, and the screen disc 3 is arranged in a sliding mode along the long axis of the powder collecting box 2 under the action of a power mechanism.
Specifically, as shown in fig. 1 and 2, the power mechanism comprises a motor 11, a main gear 12 and two power parts, the two power parts are symmetrically arranged about the main gear 12, each power part comprises a pinion 13, a rotating rod 14 and a sliding block 15, the motor 11 is arranged on the supporting frame 4, an output shaft at the bottom of the motor 11 is connected with the main gear 12, the top of the pinion 13 is rotationally connected with the supporting frame 4, the main gear 12 is meshed with the pinion 13, the sliding block 15 is slidingly arranged on the supporting frame 4, the sliding direction of the sliding block 15 is parallel to the long axis of the medicine powder collecting box 2, two ends of the rotating rod 14 are respectively rotationally connected with the bottom surface of the pinion 13 and the top surface of the sliding block 15, the connecting point of the rotating rod 14 and the bottom surface of the pinion 13 is not the center of the pinion 13, the bottom surface of the sliding block 15 is connected with the corresponding sieve tray 3 through a connecting plate 16, and the connecting plate 16 is connected with the end part of the sieve tray 3 through a plurality of screws for easy disassembly or installation.
The use principle is as follows: the motor 11 drives the main gear 12 and further drives the auxiliary gear 13, and the sliding block 15 can only move linearly, so that when the auxiliary gear 13 rotates, the rotating rod 14 can drive the sliding block 15 to move linearly in a reciprocating manner, and the screen disc 3 moves in a reciprocating manner, so that the powder can be screened rapidly and efficiently. In the scheme, the powder screening task of the two screening discs 3 can be realized by one power source of the motor 11, and each screening disc 3 can screen different powder, so that the screening rate is improved.
More specifically, as shown in fig. 2 and 4, the support frame 4 includes a transverse plate 41 and two vertical plates 42, the two vertical plates 42 are disposed at the bottom of the transverse plate 41, a guide plate 43 is disposed between the two vertical plates 42, a chute 431 penetrating through the guide plate 43 is disposed in the middle of the guide plate 43, the longitudinal section of the slide block 15 is i-shaped, and the slide block 15 is slidably matched with the chute 431.
More specifically, in order to make the screen disc 3 smoother in the reciprocating movement process, as shown in fig. 1 and 3, two rotatable wheels 31 are respectively provided at two ends of the screen disc 3, the top of the sidewall of the medicine powder collecting box 2 is provided with a bar-shaped groove 22, the wheels 31 are placed in the corresponding bar-shaped grooves 22, and the wheels 31 roll in the corresponding bar-shaped grooves 22 in the reciprocating movement process of the screen disc 3.
