Figure 1-4 As shown, according to the dustproof mechanism for a powder filling machine of the utility model embodiment, it includes a dustproof box 1 and a wrapping cover 18, a plurality of groups of partition plates 3 are evenly installed on the inner surface of the dustproof box 1, and an upper docking groove 5, a middle docking groove 4 and a lower docking groove 21 are sequentially opened between the partition plates 3 from top to bottom, and a sealing groove 20 is opened in the middle of the surface of the upper docking groove 5 and the middle docking groove 4, and a sealing disk 16 is clamped at the top position of the sealing groove 20, and one end of the sealing disk 16 is connected to the output end of the motor 14, and a docking interface 19 is opened in the middle of the surface of the lower docking groove 21, and the docking interface 19 and the docking groove are in the same straight line, and a plurality of groups of partition plates 3 are installed on the surface positions on both sides of the upper docking groove 5, the middle docking groove 4 and the lower docking groove 21. An exhaust hood 2, one end of the exhaust hood 2 is connected to a small vacuum cleaner 15 through a pipeline, guide grooves 8 are symmetrically provided at the middle positions on both sides of the upper docking groove 5, a movable plate 7 is slidably connected to the inner position of the guide groove 8, a feeding pipe 10 is installed at the middle position on the top of the movable plate 7, and the feeding pipe 10 is a retractable structure, one end of the feeding pipe 10 passes through one side of the movable plate 7 and is connected to the filling head 6, a mounting ring 11 is sleeved at the middle position of the surface of the feeding pipe 10, and the first cylinder 9 is symmetrically installed at the surface positions on both sides of the mounting ring 11, the feeding pipe 10 is two sets of pipes, one large and one small, and the small pipe is slidably and sealedly connected inside the large pipe. Since the retractable pipe setting and structure type are more common in real life, they will not be described in detail.

[0031] In one embodiment, fixing plates 13 are symmetrically welded on the top of both side surfaces of the dustproof box 1, and a second cylinder 12 is installed on the top of the fixing plate 13. The first cylinder 9 and the second cylinder 12 are both common cylinder structures, so they are not described in detail.

[0032] In one embodiment, a wrapping cover 18 is fixedly mounted on the bottom surface of the dustproof box 1 .

[0033] In one embodiment, a supporting plate 17 is welded to the bottom of one side surface of the dustproof box 1, and a small vacuum cleaner 15 is installed on the top of the supporting plate 17. The small vacuum cleaner 15 is configured to extract the gas inside the multiple docking grooves by gas suction, thereby removing the dust therein and improving the dustproof effect during filling.

[0034] In one embodiment, the sizes of the docking port 19 and the sealing groove 20 are the same as the size of the bottle mouth at the top of the bottle. The structural setting of the sealing groove 20 and the docking port 19 is to be able to better fit the top position of the bottle to be filled, thereby realizing the wrapping operation on the top, preventing external dust from invading the bottle mouth area from the surroundings, and improving the dust-proof effect of filling. Due to the variety of bottle types, the structure of the docking groove and the docking port 19 also needs to be changed accordingly. These basic operations do not exceed the understanding of people in this field, so they will not be elaborated in detail.

[0035] In one embodiment, the top structure of the wrapping cover 18 is the same size as the top of the bottle. The structure of the wrapping cover 18 is set to better fit the top position of the bottle to be filled, thereby achieving the wrapping operation on the top, preventing external dust from invading the bottle mouth area from the surroundings, and improving the dust-proof effect of filling. Due to the variety of bottle types, the structure of the wrapping cover 18 also needs to be changed accordingly. These basic operations do not exceed the understanding of people in this field, so they will not be elaborated in detail.

[0036] In one embodiment, a conical groove is provided on the top surface of the sealing groove 20 for the sealing disk 16 to be engaged.

[0037] In one embodiment, a conical protrusion is provided on the bottom surface of the sealing disk 16 for clamping the sealing groove 20. The conical protrusion on the surface of the sealing disk 16 is adapted to the conical groove on the top of the sealing groove 20. This can enhance the sealing strength and connection stability when the two are docked. At the same time, the thickness and depth of the two will not be too large, which can effectively avoid the phenomenon of being unable to separate after being stuck. Since the docking arrangement of small protrusions and grooves is frequently used in real life, it will not be elaborated in detail.

[0038] Working principle: In actual use, personnel can connect the feeding pipe 10 to the discharge port of the powder filling machine, and then when filling is needed later, they only need to move the bottle to be filled to the position directly below the wrapping cover 18, and then the entire dustproof box 1 can be moved downward by the operation of the second cylinder 12. At this time, the bottle mouth at the top of the bottle will be inserted into the docking port 19, and then the motor 14 in the middle docking groove 4 will run to move the sealing disk 16 out of the sealing groove 20. At this time, the sealing groove 20 will be exposed. At this time, with the continuous operation of the second cylinder 12, the bottle mouth will be inserted into the sealing groove 20 inside the middle docking groove 4, and then with the operation of the second cylinder 12 and the motor 14, the bottle mouth will be driven to be inserted into the sealing groove 20 in the upper docking groove 5. Then, through the operation of the first cylinder 9, the moving plate 7 will be driven to insert the filling head 6 into the bottle mouth. At this time, the filling head 6 can be used to The powder is filled into the bottle. In the overall filling operation, the bottle mouth is first inserted into the dustproof box 1, and then the vacuum cleaner is operated to suck the inside of multiple docking grooves to remove the dust therein, and then the sealing grooves 20 are opened in sequence to dock the bottle mouth with the filling head 6. The whole process is relatively shielded, so the interference of external dust can be effectively avoided. After the filling is completed, the dustproof box 1 will be gradually removed from the sealing groove 20 by resetting the second cylinder 12, and the sealing covers therein will be reclosed one by one. At this time, the area where the filling head 6 is located will be obviously isolated from the external space, which can prevent the filling head 6 from being exposed to the outside and receiving dust adhesion, thereby causing dust to be filled from the surface of the filling head 6 into the bottle during subsequent filling, which can effectively improve the overall dustproof effect and facilitate better use. The device as a whole has the advantages of multi-level isolation, good dustproof effect and filling head sealing.
