Technical Field

[0001] This utility model relates to the field of dry powder filling technology, and in particular to a dry powder precision filling device. Background Technology

[0002] Dry powder typically refers to fine particles obtained by crushing or grinding and rapidly evaporating moisture through a high-temperature airflow. It is widely used in industries such as pharmaceuticals, food, cosmetics, and chemicals. Manual filling of dry powder can easily lead to waste, so a dry powder precision filling device is needed for precise filling of dry powder.

[0003] A dry powder precision filling device is mainly used for filling dry powder. However, existing dry powder precision filling devices often experience blockages in the conveying system when handling relatively viscous or moist dry powders, due to powder clumping or poor flowability. This is especially true when the powder particles are small or have strong hygroscopicity, which may cause material jamming. This not only affects production efficiency but may also lead to equipment damage or loss of raw materials. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dry powder precision filling device, which aims to improve the problem of dry powder clumping and blockage during the filling process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dry powder precision filling device, comprising a housing, a support leg fixedly connected to the lower surface of the housing, a driving assembly provided on the outer wall of the housing for driving the structure to rotate, a worm gear rotating inside the housing, a fixed shaft fixedly connected to the lower surface of the worm gear, a gear fixedly connected to the outer wall of the fixed shaft, a gear ring meshing with the outer wall of the gear, the outer wall of the gear ring rotatably connected to the inside of the housing, a turntable fixedly connected to the inner wall of the gear ring, the outer wall of the turntable rotatably connected to the inner wall of the housing, a support rod fixedly connected to the inner wall of the turntable, a stirring rod fixedly connected to the upper surface of the support rod, stirring blades fixedly connected to the outer wall of the stirring rod, and a storage assembly provided on the upper surface of the housing for storing dry powder.

[0008] Preferably, a hydraulic cylinder is fixedly connected to the inner wall of the box, and a feed pipe is fixedly connected to the output end of the hydraulic cylinder.

[0009] Preferably, an opening and closing block is fixedly connected to the outer wall of the feed pipe, and an opening and closing cover plate is rotatably connected to the outer wall of the opening and closing block.

[0010] Preferably, the upper surface of the opening and closing cover plate is in contact with the lower surface of the feed pipe, and the lower surface of the opening and closing cover plate is slidably connected to the lower inner wall of the box body.

[0011] Preferably, a baffle is fixedly connected to the upper surface of the feed pipe, a slide rail is slidably connected to the outer wall of the baffle, and the outer wall of the slide rail is fixedly connected to the inner wall of the box.

[0012] Preferably, a feed hopper is slidably connected to the upper surface of the baffle, and the upper surface of the feed hopper is fixedly connected to the upper inner wall of the box body. The feed hopper is located below the turntable.

[0013] This utility model has the following beneficial effects:

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a dry powder precision filling device, comprising a housing 1, a support leg 2 fixedly connected to the lower surface of the housing 1, a drive assembly provided on the outer wall of the housing 1 for driving the structure to rotate, a worm gear 5 rotating inside the housing 1, a fixed shaft 6 fixedly connected to the lower surface of the worm gear 5, a gear 7 fixedly connected to the outer wall of the fixed shaft 6, a gear ring 8 meshing with the outer wall of the gear 7, the outer wall of the gear ring 8 rotatably connected to the inside of the housing 1, a turntable 9 fixedly connected to the inner wall of the gear ring 8, the outer wall of the turntable 9 rotatably connected to the inner wall of the housing 1, a support rod 10 fixedly connected to the inner wall of the turntable 9, a stirring rod 11 fixedly connected to the upper surface of the support rod 10, a stirring blade 12 fixedly connected to the outer wall of the stirring rod 11, and a storage assembly provided on the upper surface of the housing 1 for storing dry powder.

[0024] Specifically, the support legs 2 provide support and fixation for the housing 1, and the housing 1 limits the movement of the worm gear 5 to prevent deviation during operation. The worm gear 5 drives the fixed shaft 6 to rotate the gear 7 simultaneously. The gear 7 drives the gear ring 8 to rotate the inner wall turntable 9. The turntable 9 drives the support rod 10 to drive the stirring rod 11 and stirring blade 12 to stir the dry powder, preventing the dry powder from clumping and clogging the equipment.

[0025] Reference Figures 1-3 The drive assembly includes a motor 3, the outer wall of which is fixedly connected to the outer wall of the housing 1. The output end of the motor 3 is fixedly connected to a worm gear 4, and the outer wall of the worm gear 4 is meshed with a worm wheel 5. The outer wall of the worm gear 4 is rotatably connected to the inside of the housing 1. The storage assembly includes a storage tank 20, the lower surface of which is fixedly connected to the upper surface of the housing 1. The upper surface of the storage tank 20 is provided with a lid 21, and the upper outer wall of the turntable 9 is rotatably connected to the inner wall of the storage tank 20.

[0026] Specifically, the housing 1 fixes the motor 3 in place, and the motor 3 drives the worm gear 4 to rotate the worm wheel 5 inside the housing 1. The storage tank 20 can store dry powder, and the opening and closing of the lid 21 allows for convenient addition of dry powder and effectively prevents powder from scattering and polluting the environment. The turntable 9 on the inner wall of the storage tank 20 can prevent dry powder from leaking out.

[0027] Reference Figure 4 A hydraulic cylinder 13 is fixedly connected to the inner wall of the housing 1, and a feed pipe 14 is fixedly connected to the output end of the hydraulic cylinder 13. An opening and closing block 19 is fixedly connected to the outer wall of the feed pipe 14, and an opening and closing cover plate 18 is rotatably connected to the outer wall of the opening and closing block 19. The upper surface of the opening and closing cover plate 18 is in contact with the lower surface of the feed pipe 14, and the lower surface of the opening and closing cover plate 18 is slidably connected to the lower inner wall of the housing 1. A baffle 15 is fixedly connected to the upper surface of the feed pipe 14, and a slide rail 16 is slidably connected to the outer wall of the baffle 15. The outer wall of the slide rail 16 is fixedly connected to the inner wall of the housing 1. A feed hopper 17 is slidably connected to the upper surface of the baffle 15, and the upper surface of the feed hopper 17 is fixedly connected to the upper inner wall of the housing 1. The feed hopper 17 is located below the turntable 9.

[0028] Specifically, the housing 1 fixes the hydraulic cylinder 13. Activating the hydraulic cylinder 13 causes the feed pipe 14 to slide out through the inner wall of the slide rail 16 along the baffle 15. The sliding of the baffle 15 separates the dry powder in the feed hopper 17 and the feed pipe 14. The housing 1 fixes the feed hopper 17. The feed hopper 17 being located below the turntable 9 prevents the dry powder from leaking out and ensures precise pouring into the feed hopper 17. The feed pipe 14 causes the opening and closing cover 18 to slide out from the lower inner wall of the housing 1. The opening and closing block 19 opens the opening and closing cover 18 vertically, pouring out the dry powder inside the feed pipe 14, achieving the effect of quantitative dispensing.

[0029] Working Principle: When this device is needed, open the lid 21, place the dry powder to be filled into the storage tank 20, and then close the lid 21 to prevent powder from scattering during operation, which would affect environmental cleanliness and production efficiency. After the dry powder is placed, start the motor 3. The motor 3 drives the worm gear 4, which in turn rotates the worm wheel 5. The worm wheel 5 drives the gear 7 to rotate on the outer wall of the gear ring 8 via the fixed shaft 6 on the lower surface. The gear ring 8, through the rotation of the gear 7, drives the inner wall turntable 9 to rotate inside the housing 1. The rotation of the turntable 9 causes the inner wall support rod 10 to drive the stirring rod 11 to rotate inside the housing 1. During the rotation of the stirring rod 11, the dry powder inside the storage tank 20 is mixed and homogenized to achieve a better filling effect. The stirring rod 11 also causes the stirring blades 12 to simultaneously move inside the housing 1. The wall rotates, and when the stirring blades 12 rotate, they can generate shearing force on the dry powder inside the storage tank 20, preventing the dry powder from clumping and causing blockage. This allows the dry powder to be stirred and avoids clumping. The dry powder will flow faster as the turntable 9 rotates, and enter the inside of the feed pipe 14 through the feed hopper 17. At this time, the hydraulic cylinder 13 will drive the feed pipe 14 to make the baffle 15 slide outward on the inner wall of the slide 16. When the lower surface of the opening and closing cover 18 moves horizontally out from the lower inner wall of the box 1, it will be rotated by the opening and closing block 19 to make the opening and closing cover 18 open vertically and fill the dry powder inside the feed pipe 14. This device can not only effectively prevent the dry powder particles from clumping or flying, ensuring smooth powder flow during the filling process, but also quantitatively fill the dry powder to achieve a more accurate filling effect.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
