[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 described embodiments 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 work are within the scope of protection of the present invention.

[0023] As shown in the figure, the present invention discloses a powder feeding 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, a valve core guide part 41 is provided at 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, 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, 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, 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, so that 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 present invention 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 flows out from the discharge block 7.

[0025] In one embodiment of the present invention, the connector 1 is connected to the upper end of the valve core mounting portion 4 via a quick-release connector 1 8, the valve core mounting portion 4 is connected to the connecting sleeve 1 5 via a quick-release connector 2 9, and the connecting sleeve 1 5 is connected to the connecting sleeve 2 6 via a quick-release connector 3 10. The design of the quick-release connector 1 8, the quick-release connector 2 9 and the quick-release connector 3 10 allows the structure to be quickly disassembled, which is convenient for frequent cleaning, so that the powder discharging mechanism maintains a cleanliness level that meets the production requirements.

[0026] In one embodiment of the present invention, the valve core installation part 4 includes an upper connection part 43, a lifting rod moving part 44, a lower connection part 45 and a valve core guide part 41 which are sequentially distributed from top to bottom, the lifting rod is located at the lifting rod moving part 43 through a slot 42, the valve core 3 passes through the middle of the lower connection part 45 and the valve core guide part 41, and the lifting rod 2 is connected to the top of the valve core 3. The valve core guide part 41 is used to guide the movement of the valve core 3, prevent the valve core 3 from tilting, and ensure that the bottom of the valve core 3 is separated from the discharge block 7 to achieve discharge.

[0027] The valve core installation part also includes a powder guide block 46. The lifting rod passes through the lower end of the powder guide block 46 through the groove 42. The top of the powder guide block 46 is located at the upper end of the lifting rod moving part 44. Powder channels 47 are provided between the two sides of the powder guide block 46 and the lifting rod moving part. In this way, in fact, the lifting rod drives the upper end of the valve core 3 to move in the powder guide block 46, and the powder falls from the powder channels 47 on both sides, so that the sealing is achieved without affecting the cleanliness of the powder. The powder channel 47 is not connected to the lifting rod through the groove 42, and the isolation is achieved 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 connecting sleeve 2 6 and the discharge block 7, and the baffle 14 is provided with an air outlet, and the diameter of the air outlet is smaller than the diameter of the powder particles. In this way, when an external vacuum pump is connected, a vacuum is generated, so that the powder is accelerated to be discharged, but the powder cannot enter between the connecting sleeve 1 5 and the connecting sleeve 2 6 from the air outlet. Specifically, a vacuum hole 61 is provided at the connecting sleeve 2 6, and the vacuum pump is connected to the vacuum hole 61. In this way, a negative pressure is generated between the connecting sleeve 1 5 and the connecting sleeve 2 6, and the top of the tank body contacts the bottom of the connecting sleeve 2 6. The gas in the connecting sleeve 1 5 enters the air outlet from the top of the tank body, and finally enters between the connecting sleeve 1 5 and the connecting sleeve 2 6. Due to the negative pressure, the powder is discharged from the connector 1 to the discharge block 7 and enters the tank body, but the powder cannot rise from the air outlet to the space between the connecting sleeve 1 5 and the connecting sleeve 2 6, so as to accelerate the discharge.

[0031] In one embodiment of the present invention, an annular plate 15 is provided on the outer side of the lower end of the connecting sleeve 2 6, a valve cover 16 is provided on the annular plate 15, a valve bottom 17 is installed on the bottom of the valve cover 16, a space 1M is formed between the valve bottom 17, the valve cover 16, the annular plate 15 and the connecting sleeve 2 6, the valve cover 16, the annular plate 15 and the connecting sleeve 2 6 form a space 2N, and a hole 161 connected to a pipeline is provided on the upper end of the valve cover 16, and the pipeline is connected to a pump. The pump is filled with air, so that the air pressure of the space 2N is increased, so that the valve cover 16 moves downward, and finally drives the valve bottom 17 to fit with the top of the tank body, so that the tank body is stable when unloading, and the unloading is stable and does not shake.

[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 contents are merely examples and explanations of the structure of the present invention. The 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 protection scope of the present invention.
