[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As shown in the figure, the utility model discloses a powder discharging mechanism of a filling machine, including a connecting head 1, a lifting rod 2, a valve core 3, a valve core mounting part 4, a connecting sleeve 1 5 and a connecting sleeve 2 6. The bottom of the connecting head 1 is connected to the upper end of the valve core mounting part 4, and a valve core guide part 41 is provided in the middle of the bottom of the valve core mounting part 4. The lower end of the valve core 3 passes through the valve core guide part 41, and the upper end of the valve core 3 is connected to the lifting rod 2. The valve core mounting part 4 is located at the lower end of the connecting head 1 and is provided with a lifting rod passing groove 42. The upper end of the connecting sleeve 1 5 is connected to the outer side of the lower end of the valve core mounting part 4, and the outer side of the lower end of the connecting sleeve 1 5 is connected to the connecting sleeve 2 6. The lower end of the valve core 3 is located in the connecting sleeve 1 5, and the lower end of the connecting sleeve 1 5 is located in the connecting sleeve 2 6. A discharge block 7 is installed at the bottom of the connecting sleeve 1 5, and the bottom of the valve core 3 matches the outlet of the discharge block 7. When powder needs to be discharged, the lifting rod 2 is lifted, so that the valve core 3 moves upward along with the lifting rod 2. In this way, a gap is generated between the valve core 3 and the discharge block 7, so that the powder is discharged from the discharge block 7. The utility model eliminates power devices such as motors and cylinders, avoids possible pollution caused by motors and cylinders, and ensures the cleanliness of the powder.

[0024] The lifting rod 2 moves vertically at the lifting rod passing slot 42. The powder enters from the connector 1 and finally discharges from the discharge block 7.

[0025] In one embodiment of the present invention, connector 1 is connected to the upper end of valve core mounting portion 4 via quick-release connector 1 8, valve core mounting portion 4 is connected to connector sleeve 1 5 via quick-release connector 2 9, and connector sleeve 1 5 is connected to connector sleeve 2 6 via quick-release connector 3 10. The design of quick-release connector 1 8, quick-release connector 2 9, and quick-release connector 3 10 allows for quick disassembly, facilitating frequent cleaning and ensuring that the powder discharging mechanism maintains a cleanliness level consistent with production.

[0026] In one embodiment of the present invention, the valve core mounting portion 4 includes, from top to bottom, an upper connecting portion 43, a lifting rod movable portion 44, a lower connecting portion 45, and a valve core guide portion 41. The lifting rod is located in the lifting rod movable portion 43 through a slot 42. The valve core 3 passes through the middle of the lower connecting portion 45 and the valve core guide portion 41. The lifting rod 2 is connected to the top of the valve core 3. The valve core guide portion 41 is used to guide the movement of the valve core 3, preventing the valve core 3 from tilting and ensuring that the bottom of the valve core 3 is separated from the discharge block 7 to achieve discharge.

[0027] The valve core mounting portion also includes a powder guide block 46. The lifting rod passes through the lower end of the powder guide block 46 via a slot 42. The top of the powder guide block 46 is located at the upper end of the lifting rod's movable portion 44. Powder channels 47 are provided on either side of the powder guide block 46 and between the lifting rod's movable portion. In this way, the lifting rod effectively drives the upper end of the valve core 3 within the powder guide block 46, while powder falls through the powder channels 47 on both sides. This achieves a sealed structure that does not affect the cleanliness of the powder. The powder channels 47 are not connected to the lifting rod through the slot 42 and are isolated by the powder guide block 46.

[0028] In one embodiment of the present invention, a sealing member 11 is further included. The sealing member 11 is a box structure, and the lower end of the sealing member 11 is located between the valve core 3 and the valve core mounting portion 4. The sealing member 11 plays a sealing role.

[0029] In one embodiment of the present invention, an installation groove is provided in the middle of the top of the valve core 3, a connecting block 12 is placed in the installation groove, a positioning pin 13 is provided in the middle of the upper end of the connecting block 12, and the lifting rod 2 is provided with a positioning hole corresponding to the positioning pin 13, and the top of the positioning pin 13 is located at the positioning hole.

[0030] In one embodiment of the present invention, a baffle 14 is installed between the bottom of the second connecting sleeve 6 and the discharge block 7. The baffle 14 is provided with an air outlet, the diameter of which is smaller than the diameter of the powder particles. Thus, when an external vacuum pump is connected, a vacuum is generated, accelerating the powder discharging. However, the powder cannot enter the space between the first connecting sleeve 5 and the second connecting sleeve 6 from the air outlet. Specifically, a vacuum hole 61 is provided at the second connecting sleeve 6, and the vacuum pump is connected to the vacuum hole 61. In this way, a negative pressure is generated between the first connecting sleeve 5 and the second connecting sleeve 6, and the top of the tank body contacts the bottom of the second connecting sleeve 6. The gas in the first connecting sleeve 5 enters the air outlet from the top of the tank body and finally enters the space between the first connecting sleeve 5 and the second connecting sleeve 6. Due to the negative pressure, the powder is discharged from the connector 1 to the discharge block 7 and into the tank body. However, the powder cannot rise from the air outlet to the space between the first connecting sleeve 5 and the second connecting sleeve 6, thereby accelerating the discharging.

[0031] In one embodiment of the present invention, an annular plate 15 is provided on the outer side of the lower end of the second connecting sleeve 6. A valve cover 16 is mounted on the annular plate 15. A valve bottom 17 is mounted on the bottom of the valve cover 16. A space M is formed between the valve bottom 17, the valve cover 16, the annular plate 15, and the second connecting sleeve 6. The valve cover 16, the annular plate 15, and the second connecting sleeve 6 form a space N. The upper end of the valve cover 16 is provided with a hole 161 for connecting to a pipeline, which is connected to a pump. When the pump adds air, the air pressure in space N increases, which causes the valve cover 16 to move downward, ultimately driving the valve bottom 17 to fit against the top of the tank body, stabilizing the tank body during unloading and maintaining stable unloading without shaking.

[0032] In one embodiment of the present invention, a buffer plate 18 is installed at the bottom of the valve bottom 17. The buffer plate contacts the top of the tank body and plays a role in protecting the tank body and the valve bottom 17.

[0033] The above content is merely an example and explanation of the structure of the present invention. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, they should all fall within the scope of protection of the present invention.
