[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 4 As shown, a drug powder screening device comprises a device body 1, a plurality of screens 2 connected to the device body 1 and a plurality of discharge ports 3 provided on the inner wall of the device body 1, a baffle 4 is slidably connected to the inner wall of the device body 1, the baffle 4 corresponds to the position of the discharge port 3, a T-shaped block 5 is fixedly connected to one side of the baffle 4, a movable groove 6 corresponding to the position of the T-shaped block 5 is provided on the outer wall of the device body 1, the length of the movable groove 6 is greater than the length of the discharge port 3, one side of the T-shaped block 5 located outside the device body 1 is in contact with the outer wall of the device body 1, one side of the baffle 4 is in contact with the inner wall of the device body 1, the cross-section of the baffle 4 and the T-shaped block 5 is spliced ​​into an I-shape, and the bottom surface of the baffle 4 is slidably connected to the surface of the screen 2.

[0023] like Figure 1 As shown, a drug powder screening device in the utility model is similar to the existing drug powder vibrating screen structure, such as a rotary vibrating screen for drugs disclosed in the patent with publication number CN219519593U. The main improvement of the utility model is that the drug powder can be fully screened before discharging. Figures 1 to 4 As shown, when a drug powder screening device in the utility model is in use, after the staff pours the drug powder onto the screen 2, the baffle 4 will prevent the drug powder from directly entering the discharge port 3, so that the drug powder will be fully screened by the device body 1. After screening for a period of time, the staff can slide the T-shaped block 5 along the movable groove 6 to drive the baffle 4 to move and expose the discharge port 3. The fully screened drug powder can be discharged from the discharge port 3. The staff then closes the discharge port 3 through the baffle 4 to carry out the next round of drug powder screening.

[0024] By arranging a baffle plate 4 in the device body 1, arranging a T-shaped block 5 on the baffle plate 4, and arranging a movable groove 6 on the device body 1, the baffle plate 4 cooperates with the discharge port 3, so that unscreened powder cannot directly enter the discharge port 3 for discharge. By cooperating with the baffle plate 4 and the T-shaped block 5, the staff can conveniently move the baffle plate 4 and use the discharge port 3 to discharge the screened powder. Through this arrangement, the quality and effect of the powder are improved, the production efficiency is improved, and convenience is brought to the staff.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a moving ring 7 is fixedly connected to one side of the T-shaped block 5 away from the baffle 4. The opening of the moving ring 7 is arranged horizontally, and the inner diameter of the moving ring 7 is 2 cm to 3 cm.

[0026] Specifically, when the staff needs to move the T-shaped block 5, the staff can insert the index finger and the middle finger into the moving ring 7, and then bend the fingers to apply force to the moving ring 7. The movement of the moving ring 7 will drive the T-shaped block 5 and the baffle 4 to move. Through this arrangement, it is convenient for the staff to move the T-shaped block 5, the practicality of the T-shaped block 5 is improved, and the work efficiency of the staff is improved.

[0027] like Figure 3 and Figure 4 As shown, the inner wall of the moving ring 7 is provided with a protective cover 8 .

[0028] Specifically, the protective cover 8 is made of elastic materials such as rubber, silicone, sponge, etc. The protective cover 8 can provide protection for the fingers of the staff to prevent the fingers of the staff from being strangled, thereby improving the usage experience of the staff. It can also increase the friction between the hands of the staff and the movable ring 7 to prevent the hands of the staff from slipping.

[0029] like Figure 2 and Figure 3 As shown, an L-shaped guide rail 9 is fixedly connected to the inner wall of the device body 1 , the top of the baffle 4 is located between the L-shaped guide rail 9 and the inner wall of the device body 1 , and the baffle 4 is slidably connected to the L-shaped guide rail 9 .

[0030] Specifically, the L-shaped guide rail 9 can provide guidance for the baffle 4 , preventing the baffle 4 from being blocked and bent, thereby improving the stability and practicality of the baffle 4 .

[0031] like Figures 2 to 4 As shown, scrapers 10 are fixedly connected to both sides of the baffle 4 , and one side of the scraper 10 is in contact with the inner wall of the device body 1 .

[0032] like Figures 2 to 4 As shown, the side of the scraper 10 away from the device body 1 is arranged as a curved surface.

[0033] Specifically, the scraper 10 can scrape off the powder adhering to the inner wall of the device body 1, preventing the powder from entering between the baffle 4 and the device body 1 and causing the baffle 4 to bend. The scraper 10 with an arc surface improves the scraping ability of the scraper 10 and increases the practicality of the scraper 10.

[0034] like Figures 2 to 4 As shown, the length of the baffle 4 is greater than the sum of the lengths of the discharge port 3 and the moving groove 6 .

[0035] Specifically, through this arrangement, the baffle 4 can cover the discharge port 3 and the moving groove 6 at the same time to prevent drug powder from flying out of the moving groove 6, thereby increasing the practicality of the baffle 4 and the moving groove 6, reducing drug loss, and lowering production costs.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
