[0015] Reference Figure 1-Figure 5 The present invention provides a technical solution: a powder filler leakage-free feeder, comprising: A storage bin 1, on the upper end of which a cover plate 2 is detachably mounted, and a guide surface 11 is provided inside the storage bin 1; A conveying assembly 3 is fixed at the axial center position of the cover plate 2; The transfer component 5 is installed above the equipment to be loaded, and a feed port 6 is fixed on one side of the transfer component 5, and the feed port 6 is connected to the conveying component 3 through a feed hose 4; A back-blowing bin 7 is fixed on the upper end surface of the transfer assembly 5, and an air inlet 9 is provided at the upper end of the back-blowing bin 7; A vacuum generator 8 is fixed on the upper end surface of the back-blowing bin 7; The opening and closing assembly 10 is fixed on the lower end surface of the transfer assembly 5 and is connected to the equipment to be loaded.

[0016] The guide surface 11 inside the storage bin 1 can ensure that the powder slides toward the center of the storage bin 1 , thereby facilitating contact transportation of the conveying component 3 .

[0017] In this embodiment, the conveying assembly 3 includes: A driving assembly 31 is fixed at the axial center of the cover plate 2; An adjusting component 32 is slidably disposed in the driving component 31, and one end of the adjusting component 32 extends into the storage bin 1; The scattering blades 33 are configured as a plurality of blades, which are arranged circumferentially on the adjusting component 32 and extend into the storage bin 1 .

[0018] That is to say, when conveying powder, the driving component 31 causes the adjusting component 32 to slide down so as to contact the powder, and the driving component 31 drives the adjusting component 32 to rotate, thereby driving the breaking blades 33 to rotate, breaking and stirring the powder, thereby avoiding the agglomeration of the powder.

[0019] As a preferred embodiment, the driving assembly 31 includes: A fixed cylinder 311, fixed at the axial center position of the cover plate 2; A rotating blade 312 is rotatably disposed inside the fixed cylinder 311 and close to the top end; The air inlet head 313 and the air outlet head 314 are symmetrically fixed on the outer wall of the fixed cylinder 311 and correspond to the rotating blades 312; A partition plate 315 is fixed in the fixed cylinder 311 and is located below the rotating blade 312; A rotating ring 316, rotatably disposed in the partition plate 315; The second rotating ring 317 is rotatably disposed on the lower end surface of the fixed cylinder 311 .

[0020] The rotating blades 312 are driven by the gas circulation of the air inlet head 313 and the air outlet head 314, thereby driving the adjusting component 32 to rotate synchronously, so that the scattering blades 33 can continuously scatter the powder, thereby improving the smoothness of transportation.

[0021] As a preferred embodiment, the adjustment component 32 includes: An adjusting cylinder 321 is slidably disposed in the fixing cylinder 311; There are at least two limiting strips 322, which are circumferentially fixed on the outer wall of the adjusting cylinder 321; The driving disk 324 is fixed to the outer wall of the adjusting cylinder 321 and is connected to the fixing cylinder 311 in a sliding and rotatable manner.

[0022] It should be noted that a contact sensor is installed at the bottom of the adjusting cylinder 321, so as to provide a control signal for the downward movement of the adjusting cylinder 321, so as to facilitate the continuous delivery of the powder. A return spring is arranged between the driving disk 324 and the fixed cylinder 311. The fixed cylinder 311 is provided with an air inlet and an air outlet, and the air inlet and the air outlet are located below the partition plate 315. When the adjustment cylinder 321 needs to slide down, the driving disk 324 is pressed down through the air inlet hole of the fixed cylinder 311, so that the driving disk 324 drives the adjustment cylinder 321 to slide down and continuously convey the powder. When the powder material in the storage bin 1 is conveyed, the air is exhausted through the air outlet, and the reset spring resets the driving disk 324 at the same time, which is convenient for subsequent conveying.

[0023] As a preferred embodiment, a plurality of auxiliary openings 323 are opened on the bottom circumference of the adjusting cylinder 321, and the plurality of auxiliary openings 323 are located above the dispersing blades 33. The adjusting cylinder 321 is slidably connected with the rotating ring 1 316 and the rotating ring 2 317 by means of a limit strip 322.

[0024] That is to say, when the adjusting cylinder 321 rotates, the rotating ring 1 316 and the rotating ring 2 317 rotate synchronously, wherein the adjusting cylinder 321 continuously slides down while rotating, thereby continuously conveying the powder, and the powder can be assisted in conveying through the auxiliary port 323 during conveying, thereby preventing the powder from adhering to the scattering leaf 33.

[0025] In this embodiment, the transfer component 5 includes: An outer cylinder 51, inside which an inner cylinder 52 is coaxially fixed, and the bottoms of the outer cylinder 51 and the inner cylinder 52 are both provided with conical surfaces; The back-blowing groove 53 is provided between the outer cylinder 51 and the inner cylinder 52 and is connected to the back-blowing chamber 7; The backflush holes 54 are arranged in plurality and opened on the tapered surface of the inner tube 52 .

[0026] As a preferred embodiment, a filter screen is fixed to the top of the inner cylinder 52, and the output end of the vacuum generator 8 passes through the back-blowing bin 7 and is located above the filter screen.

[0027] The powder can be separated from the gas by the filter, and the powder can be continuously blown through the back-blowing hole 54, thereby preventing the powder from being statically accumulated in the inner cylinder 52, and further preventing the powder from agglomerating.

[0028] As a preferred embodiment, the opening and closing assembly 10 includes: A discharge bin 101 is fixed on the outer cylinder 51; An opening and closing cylinder 102 is hinged on the upper end surface of the discharge bin 101; The sealing plate 103 is hinged in the discharge bin 101 and is flush with the lower end surface of the inner cylinder 52 when in a horizontal position; The hinged rod 104 has one end fixed on the blocking disk 103 and the other end hinged on the output end of the opening and closing cylinder 102 .

[0029] It should be noted that the efficiency of powder entering the device to be loaded can be adjusted by the opening and closing degree of the blocking disk 103, thereby achieving precise control.

[0030] First, the powder to be loaded is placed in the storage bin 1 to avoid the escape of the powder. Then, during transportation, the adjusting component 32 is always kept in contact with the powder material, thereby improving the loading efficiency and maintaining continuous transportation of the powder. When in contact with the powder, the powder can be dispersed and stirred by the dispersing leaves 33, thereby avoiding the agglomeration of the powder. After the powder is transported to the transfer component 5, the powder can be continuously blown through the backblowing holes 54, thereby avoiding the static accumulation of the powder in the transfer component 5, further avoiding the agglomeration of the powder, so that the transfer component 5 can be opened by the opening and closing component 10 during loading, so that the powder can quickly fall into the equipment to be loaded.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
