All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] like Figures 1-5 The powder dispensing and anti-leakage device shown includes a conveyor belt 6 and a mounting plate 1. The conveyor belt 6 is arranged at intervals above the mounting plate 1, and clamps 7 are arranged on the conveyor belt 6 for installing powder-liquid dual-chamber bags 8. A lifting device is arranged on the mounting plate 1, and a funnel is arranged on the lifting device. Powder storage chambers 9 are arranged at intervals above the funnel, and a powder lowering cup 10 is arranged at the bottom of the powder storage chamber 9 facing the funnel.

[0022] In this embodiment, the powder storage chamber 9 is used to store powder, and the powder lowering cup 10 is used to feed the powder into the funnel. When the conveyor belt 6 moves the clamp 7 with the powder-liquid double-chamber bag 8 installed to the designated position, the opening at the top of the powder chamber of the powder-liquid double-chamber bag 8 is opened, and the lifting device moves the funnel downward. The bottom end of the funnel is inserted downward into the bottom of the powder chamber, and then the powder is filled. Setting up the funnel can avoid the generation of dust, thereby preventing the powder from adhering to the outside of the soft packaging bag. After the funnel is inserted into the bottom of the powder chamber, it avoids the powder from contacting the inner wall surface of the powder chamber seal, thereby avoiding the powder from affecting the sealing effect of the seal.

[0023] The powder storage chamber 9 is equipped with a stirrer for mixing the powder, and a dispensing screw is installed in the powder storage chamber 9. The dispensing screw is vertically arranged and used for quantitative dispensing of powder.

[0024] In this embodiment, the powder storage cabin 9 is provided with a stirrer and a dispensing screw. The stirrer is used to stir the powder to make it looser, facilitating the dispensing of the powder. The dispensing screw is used to control the amount of powder in each powder liquid double chamber bag 8 to ensure that the amount of powder in each powder liquid double chamber bag 8 is consistent. The stirrer and the dispensing screw are prior art and will not be described in detail here.

[0025] The mounting plate 1 is provided with lifting cylinders 2 at intervals at the bottom. The movable end of the lifting cylinder 2 at the top is connected with a connecting rod 3. The connecting rod 3 is connected with a plurality of vertically arranged support rods 4 at the top. The support rods 4 pass through the mounting plate 1 at the top and are connected with lifting bars 5. The lifting bars 5 are used to cooperate with the clamps 7 to control the clamps 7 to open.

[0026] In this embodiment, the clamp 7 is prior art. The height of the clamp 7 at the abutting position with the lifting bar 5 is controlled by the lifting bar 5, thereby controlling the clamp 7 to open. The opening at the top of the powder cavity is controlled by the clamp 7. The clamp 7 is prior art and will not be described in detail here.

[0027] The lifting device includes telescopic rods 12, connecting plates 13 and support plates 14. The telescopic rods 12 are vertically arranged on both sides of the conveying belt 6. The bottom surface of the connecting plate 13 at both ends is connected with the top end of the telescopic rod 12. The bottom surface of the horizontally arranged support plate 14 is connected with the top surface of the connecting plate 13.

The lower powder nozzle 11 is provided with a groove at the top, the inner diameter of which is adapted to the outer diameter of the bottom of the lower powder cup 10. The lower powder port is arranged at the bottom of the groove. A gasket can be arranged in the groove. The gasket is used to adjust the distance between the bottom end of the lower powder cup 10 and the bottom surface of the groove, thereby adjusting the gap between the bottom of the lower powder cup 10 and the bottom surface of the groove, facilitating the dispensing of different powders.

[0030] In this embodiment, the lower powder nozzle 11 can be connected at the bottom end of the lower powder cup 10 or a locking screw is arranged on the side surface of the lower powder nozzle 11 to connect the lower powder cup 10 and the lower powder nozzle 11.

[0031] Working principle: the conveyor belt 6 moves the clamp 7 to the designated position and stops, then the lifting cylinder 2 controls the lifting support 5 to move upward, the lifting support 5 controls the clamp 7 to open the powder cavity opening at the top of the powder-liquid double-chamber bag 8, then the telescopic rod 12 drives the connecting plate 13 and the supporting plate 14 to move downward, the supporting plate 14 drives the hopper to move downward, the bottom end of the hopper moves downward from the powder cavity top opening, then inserts into the powder cavity bottom end, the stirrer in the powder storage cavity stirs the powder, the powder falls into the lower powder cup 10 and is quantitatively packaged by the packaging screw, then the quantitatively packaged powder passes through the lower powder nozzle 11 and falls into the hopper under the action of gravity, then falls into the powder cavity.

[0032] Although the preferred embodiments of the present application have been described, those skilled in the art who understand the basic inventive concept can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
