Description

Technical Field

[0001] This utility model belongs to the field of particle powder feeding technology, and in particular relates to a fine particle powder adding device. Background Technology

[0002] In industrial, chemical, and food production, additives are often added to raw materials to obtain better products, faster reaction results, and longer shelf life.

[0003] Therefore, the addition device is widely used. For example, patent number CN202421330633.4 discloses a technical solution for powder addition. However, this technical solution still has some problems in use. This technical solution uses a screw feeder in conjunction with a feeding pipe to add materials, and the amount of powder added can be controlled according to the rotation speed of the screw feeder, thereby achieving quantitative addition of materials. However, in actual use, due to the large friction between fine particles, the flowability is often poor. This makes it difficult to accurately control the amount added during the addition process, which may result in uneven addition or blockage of the feeding pipe, thereby affecting the accuracy and efficiency of the equipment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a fine powder adding device, which solves the problem that the existing equipment cannot accurately control the amount of powder added, thus affecting the accuracy of the addition.

[0006] A metering component, mounted on a mounting frame, is used for metering material in a hopper. It includes a metering bucket that is slidably mounted on the mounting frame and is in contact with the bottom discharge port of the hopper. The end of the metering bucket is also in contact with a guide pipe.

[0007] A movable component, located at the rear of the mounting frame, is used to drive the cyclic movement of the metering container, including a threaded rod movably mounted on the mounting frame, with the end of the threaded rod fixedly mounted on the metering container;

[0024] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown in the figure, the fine powder adding device provided in this embodiment of the present invention includes a fixing plate 1, a material box 2 disposed on the fixing plate 1, a plurality of material guide pipes 3 disposed on the fixing plate 1, wherein the ends of the material guide pipes 3 are interconnected with the bottom of the material box 2, and a mounting frame 4 fixedly disposed on the fixing plate 1, and further includes:

[0026] A metering component, mounted on the mounting frame 4, is used for metering the material in the hopper 2. It includes a metering bucket 5 that is slidably mounted on the mounting frame 4, and the metering bucket 5 is in active contact with the bottom discharge port of the hopper 2. The end of the metering bucket 5 is also in active contact with the guide pipe 3.

[0027] A movable component, located on the rear side of the mounting frame 4, is used to push the metering barrel 5 to move cyclically. It includes a threaded rod 9 movably mounted on the mounting frame 4, and the end of the threaded rod 9 is fixedly mounted on the metering barrel 5.

[0028] The drive assembly, mounted on the fixed plate 1, is used to drive the movement of the threaded rod 9.

[0029] As a preferred embodiment of this utility model, the quantitative component also includes a flip plate 6 rotatably disposed on the lower side of the quantitative barrel 5, a lifting plate 8 fixedly disposed at the bottom of the mounting frame 4 that is in movable contact with the flip plate 6, and a sealing plate 7 fixedly disposed on the quantitative barrel 5 for sealing the bottom discharge port of the material box 2, which facilitates the quantitative feeding of materials and avoids the flow speed of materials being affected due to high friction, thereby affecting the accuracy of feeding.

[0030] As a preferred embodiment of this invention, the movable component further includes a rotating sleeve 10 rotatably mounted on the mounting frame 4, a threaded rod 9 threadedly connected inside the rotating sleeve 10, a torsion spring 11 for resetting the rotating sleeve 10, a guide rod 12 slidably mounted on the threaded rod 9, and a full gear 13 mounted on the rotating sleeve 10. This facilitates the movement of the metering container 5, enabling precise dispensing from the metering container.

[0031] As a preferred embodiment of this utility model, the drive assembly includes a drive motor 15 mounted on a fixed plate 1. The output end of the drive motor 15 is connected to a half gear 16 that meshes with the full gear 13, enabling the metering barrel 5 to achieve metered cyclic feeding, further improving the accuracy of its metered feeding.

[0032] As a preferred embodiment of this utility model, a dispersing fan blade 14 is also provided inside the feed pipe 3, and the dispersing fan blade 14 is connected to the output end of the drive motor 15 for transmission, which facilitates the dispersion of the fed material and makes the feeding more uniform.

[0033] As a preferred embodiment of this utility model, the bottom of the feed pipe 3 is trumpet-shaped, and the dispersing fan blade 14 is located inside the trumpet shape. An inclined receiving plate is installed at the bottom of the dispersing fan blade 14, and the receiving plate is located on the lower side of the metering bucket 5, which makes it more convenient for the equipment to discharge materials and avoids the overflow of materials during discharge.

[0034] The working principle of this utility model:

[0035] refer to Figure 1 The fixed plate 1 is equipped with multiple guide pipes 3, which allows the equipment to add multiple materials simultaneously, making material feeding more convenient and faster. (See reference) Figure 3 In the initial state, the metering bin 5 is located below the material bin 2, and the tilting plate 6 is blocked by the lifting plate 8, which seals the metering bin 5. At this time, the material in the material bin 2 can be fed into the metering bin 5 through the material outlet at the bottom. When the equipment is working, the specific operation is as follows:

[0036] refer to Figure 3 Turn on the drive motor 15 to drive the half gear 16 to rotate in the forward direction. When the half gear 16 rotates in the forward direction, its teeth drive the full gear 13 to rotate in the forward direction. When the full gear 13 rotates in the forward direction, since one end of the torsion spring 11 is fixed to the rotating sleeve 10 and the other end is fixed to the mounting bracket 4, the torsion spring 11 is compressed when the full gear 13 drives the rotating sleeve 10 to rotate in the forward direction. The threaded rod 9 will move to the left under the limiting guidance of the guide rod 12. When the threaded rod 9 moves to the left, it pushes the metering container 5 to slide on the mounting bracket 4. At this time, the material placed in the metering container 5 will move along with it. (Reference) Figure 5When the metering drum 5 moves to a certain position, the tilting plate 6 separates from the lifting plate 8, and the tilting plate 6 tilts, opening the metering drum 5. Simultaneously, the material inside the metering drum 5 is discharged and enters the... Figure 3 On the receiving plate, the material is then conveyed to the guide pipe 3, thus completing the quantitative feeding of the material. (Refer to...) Figure 4 As the top of the metering bucket 5 gradually separates from the bottom discharge port of the material bin 2, the sealing plate 7 will gradually seal the discharge port to prevent spillage. (Refer to...) Figure 3 When the half gear 16 disengages from the full gear 13, the rotating sleeve 10 will rotate in the opposite direction under the torque of the torsion spring 11. At this time, the metering bucket 5 can be moved to the discharge port of the material box 2 again, so as to receive the material again. Since the volume of the metering bucket 5 is constant, the amount of material conveyed by the metering bucket 5 each time is equal, thus realizing the equal amount of material conveying.

[0037] refer to Figure 3 When the drive motor 15 is working, it will simultaneously drive the dispersing fan blade 14 to rotate. When the material in the metering bucket 5 enters the guide pipe 3 and falls to the position of the dispersing fan blade 14, the dispersing fan blade 14 will disperse the material, making it more even when it is dispensed, thus avoiding material accumulation and affecting its later use.

[0038] This invention effectively measures the amount of material fed into the device through a quantitative component, making the quantity of material entering the feed tube 3 more accurate. This avoids the instability of the flow rate when the material falls due to its small size and high friction, which would otherwise prevent the device from accurately feeding the material. In addition, the dispersion fan blades 14 at the bottom of the feed tube 3 effectively ensure the dispersion of the material during each feeding process, preventing the accumulation of material.
