[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1-3 This invention describes a specific embodiment of a screw filling machine's anti-leakage mechanism, comprising a support frame 1, a fixed adjustment assembly on the support frame 1, a lifting assembly on the fixed adjustment assembly, a rotating assembly on the lifting assembly, and a movable plate 16 on the movable plate 16. A fixed seat 17 is mounted on the fixed seat 17, and a rotating shaft 18 is mounted on the rotating shaft 18. A semi-circular baffle 19 is mounted on the rotating shaft 18, and a driving assembly is mounted on the fixed seat 17. The semi-circular baffle 19 is located at the outlet of the screw filling machine. The rotating shaft 18 can drive the semi-circular baffle 19 to rotate, thereby blocking the outlet of the screw filling machine and preventing powder from falling or leaking due to machine vibration during the filling gap.

[0023] Advantageously, the fixing seat 17 is provided with reinforcing ribs. The reinforcing ribs increase the strength of the fixing seat 17.

[0024] Advantageously, the drive assembly includes a first sprocket 20 and a motor 22. The first sprocket 20 is mounted on the end of the rotating shaft 18 away from the semi-circular baffle 19. The motor 22 is mounted on the fixed base 17. The driving end of the motor 22 is provided with a second sprocket 23. The first sprocket 20 and the second sprocket 23 are provided with a transmission chain 24 to drive the motor 22. The motor 22 drives the second sprocket 23 to rotate, and the transmission chain 24 drives the first sprocket 20 to rotate under the action of the second sprocket 23.

[0025] Advantageously, the motor 22 is fixed to the mounting base 17 by screws, which facilitates the installation and removal of the motor 22 on the mounting base 17.

[0026] Advantageously, the fixed adjustment assembly includes a slide groove 5 and a connecting frame 2. The slide groove 5 is disposed on the support frame 1, and a slider 6 is movably disposed on the slide groove 5. A sliding plate 8 is disposed on the slider 6. The connecting frame 2 is mounted on the support frame 1, and a threaded rod 3 is movably disposed on the connecting frame 2. A stop block 4 is disposed at one end of the threaded rod 3. A lead screw 7 is movably disposed on the support frame 1 and is movably connected to the slider 6. The support frame 1 can be placed on the screw dispensing machine. When the threaded rod 3 is rotated, the threaded rod 3 rotates and moves on the connecting frame 2. The stop block moves with the threaded rod 3 and abuts against the screw dispensing machine. Thus, the fixed frame 9 can be fixed on the screw dispensing machine. When the lead screw 7 is rotated, the lead screw 7 drives the slider 6 to slide on the slide groove 5, and the sliding plate 8 moves with the slider 6.

[0027] Advantageously, the lead screw 7 is provided with a rotating handle, which facilitates the rotation of the lead screw 7.

[0028] Advantageously, the lifting assembly includes a fixed frame 9 and a rack 10. The fixed frame 9 is mounted on the sliding plate 8, and the rack 10 is movably mounted on the fixed frame 9. A rotating shaft 11 is movably mounted on the fixed frame 9, and a threaded hole 15 is provided on the fixed frame 9. A gear 12 is provided on the rotating shaft 11 and meshes with the rack 10. A rotating plate 13 is provided on the rotating shaft 11, and a bolt 14 is movably mounted on the rotating plate 13. Rotating the rotating plate 13 causes the rotating shaft 11 to rotate on the fixed frame 9. The gear 12 follows the rotation of the rotating shaft 11, causing the rack 10 to move. The rack 10 can drive the moving plate 16 to move and adjust the lifting height. After adjusting to a certain height, the rotating shaft 11 stops rotating. Rotating the bolt 14 on the rotating plate 13 causes the bolt 14 to enter the threaded hole 15 on the fixed frame 9, thereby limiting the rotation of the rotating shaft 11.

[0029] Advantageously, the threaded holes 15 are provided in a plurality of manner, and the plurality of threaded holes 15 are arranged at equal intervals around the circumference, which facilitates fixing the rotating plate 13 at different angles.

[0030] Working principle of this utility model:

[0031] First, the support frame 1 can be placed on the screw dispensing machine. Rotating the threaded rod 3 causes it to rotate and move on the connecting frame 2. The abutment plate moves with the threaded rod 3 and abuts against the screw dispensing machine. Then, the fixing frame 9 can be fixed on the screw dispensing machine. Rotating the lead screw 7 causes the slider 6 to slide on the slide groove 5. The sliding plate 8 moves with the slider 6, positioning the semi-circular baffle 19 below the screw dispensing machine outlet. Rotating the rotating plate 13 causes the rotating shaft 11 to rotate on the fixing frame 9. The gear 12 rotates with the rotating shaft 11, causing the rack 10 to move. The rack 10 can move the moving plate 16 to adjust its height. The semi-circular baffle 19 approaches the screw dispensing machine. At the machine outlet, stop rotating and rotate the bolt 14 on the rotating plate 13 so that the bolt 14 enters the threaded hole 15 on the fixed frame 9, thereby limiting the rotation shaft 11 and driving the motor 22. The motor 22 drives the second sprocket 23 to rotate. The transmission chain 24 drives the first sprocket 20 to rotate under the action of the second sprocket 23. The rotating shaft 18 follows the first sprocket 20 to rotate. The rotating shaft 18 can drive the semi-circular baffle 19 to rotate, so that it blocks the outlet of the screw filling machine to prevent powder from falling or leaking due to machine vibration during the filling gap. When the blocking is not needed, the semi-circular baffle rotates and does not block the outlet of the screw filling machine.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
