[0021] 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.

[0022] See also Figure 1-5The utility model provides a technical solution: a quantitative feeding device for a powder filling machine, comprising a base 1, a support frame 4 is fixedly connected to the upper surface of the base 1, and a conveyor belt 2 is symmetrically fixedly installed on both sides of the support frame 4, a guide plate 3 is provided on the front surface of the support frame 4, and a feeding port 302 is opened inside the two ends of the guide plate 3, and a feeding pipe 301 is fixedly connected to the inner wall of the feeding port 302, and the feeding pipe 301 is fixedly connected to the upper surface of the conveyor belt 2, two groups of packaging boxes 10 are symmetrically provided above the guide plate 3, and the lower surface of the packaging box 10 is in contact with the upper surface of the guide plate 3. A support plate 505 is fixedly connected to one side surface of the packaging box 10, and a driving frame 502 is fixedly connected to the middle of the support plate 505. A driving mechanism is provided on one side of the driving frame 502. A leakage component is provided on the lower surface of the packaging box 10. Cleaners 7 are symmetrically provided on the lower surfaces of both sides of the support frame 4. L-shaped plates 9 are symmetrically fixedly connected to the side surfaces of the two ends of the guide plate 3, and one end of the L-shaped plate 9 is fixedly connected to the side surface of the support frame 4. A material box 6 is fixedly connected to the upper surface of the support frame 4, and a discharge pipe 8 is fixedly connected to the lower surface of the material box 6. The lower end of the discharge pipe 8 is aligned with the packaging box 10.

[0023] As a technical optimization solution of the present invention, the driving mechanism includes a driving motor 5, and the driving motor 5 is fixedly installed on the rear surface of the support frame 4. One end of the driving motor 5 passes through the support frame 4 and is fixedly connected to a turntable 501, and one side surface of the turntable 501 is fixedly connected to a driving block 503. The driving block 503 is located inside the driving frame 502. When the driving motor 5 drives the turntable 501 to rotate, the driving block 503 can drive the driving frame 502 to reciprocate. Therefore, the driving frame 502 drives the packaging box 10 to reciprocate through the support plate 505. Therefore, the packaging box 10 can continuously load the powder and avoid discontinuity when the powder is filled and quantitatively discharged.

[0024] As a technical optimization solution of the present invention, a horizontal plate 1001 is provided between the symmetrically arranged packaging boxes 10, and the upper surface of the horizontal plate 1001 is on the same horizontal plane as the lower surface of the discharge pipe 8. When the packaging boxes 10 reciprocate, when the lower end of the discharge pipe 8 is located between the symmetrically arranged packaging boxes 10, the lower end of the discharge pipe 8 can be blocked by the horizontal plate 1001 to prevent powder material from scattering to the outside.

[0025] As a technical optimization solution of the present invention, the leakage component includes a mounting groove 1004 on the lower surface of the packaging box 10, and the interior of the mounting groove 1004 is hinged with a bottom plate 1003. Therefore, when the packaging box 10 moves to the top of the discharge port 302, the bottom plate 1003 will be opened by gravity, so that the powder material falls into the material box on the upper surface of the conveyor belt 2 through the discharge pipe 301 below the discharge port 302.

[0026] As a technical optimization solution of the present invention, the cleaner 7 includes a cleaning head 701, and the internal sliding connection of the cleaning head 701 is a sealing plate 702, the lower surface of the cleaning head 701 is fixedly connected to the air outlet 705, and the lower end of the air outlet 705 is aligned with one end of 304, one end of the packaging box 10 is fixedly connected to a push plate 1002, and the push plate 1002 is aligned with the sealing plate 702, and a reset mechanism is provided on one side of the sealing plate 702. When the driving mechanism pushes the packaging box 10 to move above the discharge port 302, the push plate 1002 at one end of the packaging box 10 can push the sealing plate 702 to move after the powder material falls, so the sealing plate 702 will open the air outlet 705, and at this time, the interior of the packaging box 10 will be blown, thereby cleaning the interior of the packaging box 10.

[0027] As a technical optimization solution of the present invention, the reset mechanism includes a reset spring 703, one end of the reset spring 703 is fixedly connected to one side surface of the blocking plate 702, one end of the blocking plate 702 is fixedly connected to a vertical plate 704, the upper end of the vertical plate 704 is fixedly connected to the lower surface of the cleaning head 701, and can drive the blocking plate 702 back to its original position after the packaging box 10 is withdrawn to its original position, thereby blocking the air outlet 705 to prevent the air outlet 705 from continuing to blow air.

[0028] As a technical optimization solution of the present invention, one end of the support plate 505 is fixedly connected to the limiting rod 504, and the side surface sliding sleeve of the limiting rod 504 is provided with a limiting ring. The side surface of the limiting ring is fixedly connected to the side surface of the support frame 4 through the support rod, and can limit the driving frame 502. Therefore, when the driving frame 502 reciprocates, the stability of the driving frame 502 and the support plate 505 is improved, and the movement stability of the packaging box 10 is further improved.

[0029] When the container 10 is in the working state, the support plate 505 drives the container 10 to move to the lower feeding port 302, and the push plate 1002 moves to the lower feeding port 302. Then, when the container 10 is moved to the upper part of the feeding port 302, the push plate 1002 is moved to the lower feeding port 302. The group packaging box 10 will receive the material, and the bottom plate 1003 on the lower surface of the packaging box 10 will fall down. At this time, the powder will fall down and enter the material box on the upper surface of the conveyor belt 2 through the discharge port 302 and the discharge pipe 301. Then, the packaging box 10 will move a distance toward one end of the guide plate 3 under the action of the driving mechanism, so that the push plate 1002 will push the sealing plate 702 to slide. At this time, the air outlet 705 will be opened, so as to blow air into the interior of the packaging box 10 to clean the interior of the packaging box 10. After that, the packaging box 10 will return to its original position to receive the material, and at the same time, the sealing plate 702 returns to its original position under the action of the return spring 703 and the vertical plate 704 to seal the air outlet 705, and then the operation is cyclically repeated.
