[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A powder dispensing device includes a powder hopper 1, a manual disc valve 3, a sight glass 5, a powder dispensing screw 6, and a powder dispensing pipe 9; a vibrator 2 is connected to the side wall of the powder hopper 1; the lower end of the powder hopper 1 is connected to the manual disc valve 3, the lower end of the manual disc valve 3 is connected to the powder dispensing pipe 9, and the powder dispensing screw 6 is installed inside the powder dispensing pipe 9; a sight glass 5 for observing the powder inside the powder dispensing pipe 9 is installed on the powder dispensing pipe 9.

[0026] In the powder feeding device provided in this embodiment, since a vibrator 2 is connected to the side wall of the powder hopper 1, the powder on the inner wall of the powder hopper 1 can be shaken off, thereby reducing the amount of residual powder in the device. In addition, by setting the sight glass on the powder feeding pipe for observing the powder in the powder feeding pipe, this embodiment can accurately control the amount of powder fed and effectively observe the remaining powder inside the mechanism during equipment operation.

[0027] Specifically, the sight glass 5 is made of transparent material. In some embodiments of this utility model, the sight glass 5 is a cylindrical structure; the powder supply pipe 9 includes an upper pipe section and a lower pipe section, the upper pipe section is connected to the manual disc valve 3, and the two ends of the sight glass 5 are respectively connected to the upper pipe section and the lower pipe section; or, the two ends of the sight glass 5 are respectively connected to the powder supply pipe 9 and the manual disc valve 3; or, the upper end of the sight glass 5 is connected to the lower end of the powder supply pipe 9.

[0028] In some alternative embodiments of this utility model, the sight glass 5 is a sheet-like structure; an installation port is provided on the powder supply pipe 9, and the sight glass 5 is installed in the installation port. The sight glass 5 is made of a high-temperature resistant transparent material, which can not only withstand moist heat sterilization, but also effectively observe the remaining powder inside the mechanism during equipment operation.

[0029] The powder dispensing device also includes a motor 4, and a powder dispensing screw 6 is connected to the output end of the motor 4 via a transmission device. The powder dispensing device also includes a column 10, and the powder hopper 1 is connected to the column 10 via a clamp 8. The motor 4 is connected to the column 10. A cover is provided around the motor 4. A nozzle 7 is connected to the lower end of the powder dispensing pipe 9.

[0030] Specifically, the vibrator 2 is not limited to the powder hopper 1, but can also be set at the manual butterfly valve 3 position to shake off the powder remaining on the inner wall of the powder feeding pipe 9 and the powder feeding screw 6 at the tail end, thereby more effectively solving the problem of residual powder.

[0031] Specifically, the powder dispensing screw 6 can achieve precise powder dispensing. After most of the powder is filled, there is powder stuck inside the powder can and on the screw. Activating the vibrator causes the powder to fall off, further reducing residual powder.

[0032] Specifically, a nozzle 7 is connected to the lower end of the powder feeding pipe 9. Due to the gap between the screw and the outside, some specific powders may leak. The nozzle 7 can effectively prevent powder leakage. The nozzle 7 helps to gather and center the powder. Its structure is a cylinder with one end open and the other end semi-closed with a small hole in the center, which can effectively control the powder falling.

[0033] This powder dispensing device is simple to operate and has a reasonable structure. The powder hopper is locked with a clamp, and a manual disc valve at the bottom controls the total filling volume. The lower end features a powder dispensing screw for precise control of the dispensing amount. It is also equipped with a sight glass to observe the powder level. A vibrator at the top provides vibration at the tail end, reducing powder residue. The entire structure is rotatable, allowing for more operational space during installation and disassembly. The structure is simple and operates smoothly.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
