[0035] The present application provides a powder mixing device with a drying function, such as Figure 1 and Figure 5As shown, the powder mixing device with drying function may include a bracket 1, a mixing barrel 2, a feeding port 21, a discharging port 22, a servo motor 23, a driving gear 24, a feeding assembly 3, a vibration assembly 4 and an air jet assembly 5; wherein, the mixing barrel 2 is fixedly mounted on the bracket 1; the feeding port 21 is arranged at the top of the mixing barrel 2; the discharging port 22 is arranged at the bottom of the mixing barrel 2; the servo motor 23 is fixedly mounted on the side of the mixing barrel 2 facing the bracket 1; the driving gear 24 is fixedly mounted on the output end of the servo motor 23; the feeding assembly 3 is arranged in the mixing barrel 2; the vibration assembly 4 is arranged on the bracket 1, and the connecting part of the vibration assembly is located in the mixing barrel 2 and is arranged in conjunction with the feeding assembly 3; the air jet assembly 5 is arranged on the bracket 1 and connected to the feeding assembly 3.
[0036] Among them, the mixing barrel 2 is fixedly installed on the bracket 1; the feeding port 21 is set at the top of the mixing barrel 2; the discharge port 22 is set at the bottom of the mixing barrel 2; the servo motor 23 is fixedly installed on the side of the mixing barrel 2 facing the bracket 1, and is used to drive the movement of each functional component.
[0037] like Figure 2 As shown, the driving gear 24 is fixedly installed at the output end of the servo motor 23; the feeding assembly 3 is arranged in the mixing barrel 2; the feeding assembly 3 is used to control the feeding and is arranged corresponding to the positions of the feeding port 21 and the discharging port 22.
[0038] The vibration component 4 is arranged on the bracket 1, and the connecting part of the vibration component 4 is located in the mixing barrel 2 and is arranged in conjunction with the feeding component 3 to control the vibration of the feeding component 3, thereby realizing automatic feeding of the powder through vibration and being able to turn the powder evenly.
[0039] like Figure 1 As shown, the jet assembly 5 is arranged on the bracket 1 and connected to the feeding assembly 3, and is used to blow the heated gas into the mixing barrel 2 to dry the powder through the heat exchange effect of the hot gas.
[0040] Specifically, the powder is gradually transferred from the feeding port 21 to the discharging port 22 by the vibration component 4 and the feeding component 3, and the powder is evenly turned by vibration, so that the powder can be evenly dried. Secondly, the heated air is evenly blown onto the powder through the jet component 5 to accelerate the drying process. Through the cooperation of the above structures, not only the drying rate and the uniformity of drying can be improved, but also the feeding speed can be controlled by vibration, saving the resource cost of mixing and drying.
[0041] Please continue to combine Figure 2 and Figure 3 For reference, in an exemplary embodiment, the feeding assembly 3 may include a mounting post 32 and a spiral feeding plate 33. The mounting post 32 is movably arranged inside the mixing barrel 2, and the spiral feeding plate 33 is fixedly mounted on the mounting post 32.
[0042] Specifically, the mounting column 32 is set at the center of the mixing barrel 2, and the spiral feeding plate 33 is spirally set on the mounting column 32 and is inclined downward. After the powder falls onto the spiral feeding plate 33, it can be fed downward along the downward inclined spiral feeding plate 33.
[0043] Please continue to combine Figure 2 and Figure 4 For reference, in an exemplary embodiment, the vibration assembly 4 may include a fixed tube 11, a driven gear 44, a drive disc 43, a drive block 431, a movable disc 42, a guide disc 41, and a connecting portion. The fixed tube 11 is fixedly mounted on the bracket 1, the driven gear 44 is rotatably mounted on the fixed tube 11 and meshes with the drive gear 24, the drive disc 43 is fixedly mounted on the driven gear 44, four drive blocks 431 are provided, fixedly mounted on the drive disc 43 and arranged in a circular array, one side of the drive blocks 431 is provided with an inclined surface, the movable disc 42 is movably mounted on the drive disc 43 and is provided with protrusions on all sides, the guide disc 41 is sleeved on the movable disc 42 and has a sliding groove that matches the protrusions, and the connecting portion may include a fixed post 31 and a connecting post 34. The fixed post 31 is fixedly mounted on the inner top wall of the mixing barrel 2; the connecting post 34 is fixedly mounted on the movable disc 42, passes through the mixing barrel 2, and is rotatably connected to the mounting post 32.
[0044] Specifically, the servo motor 23 drives the driving gear 24 to rotate, and then drives the driven gear 44 meshing with it to rotate. When the driving disk 43 and the driving block 431 fixed thereon rotate with it, the movable disk 42 can be repeatedly lifted up to move upward along the guide disk 41. After being lifted up, the movable disk 42 is reset under the action of gravity, forming a repeated vibration effect.
[0045] Furthermore, a groove adapted to the fixing post 31 is formed on the top of the installation post 32 , and the installation post 32 and the fixing post 31 are slidably connected.
[0046] Specifically, the movable plate 42 transmits vibration to the mounting post 32 via the connecting post 34 , and the mounting post 32 performs up and down reciprocating motion under the guidance of the fixed post 31 .
[0047] Please combine Figure 2 、 Figure 5 、 Figure 6 and Figure 8For reference, in an exemplary embodiment, the jet assembly 5 may include a guide cylinder 51, an airbag 52, a driven bevel block 53, a driving bevel block 54, an air inlet 511, and an air supply pipe 55. The guide cylinder 51 is fixedly mounted on the bracket 1, the airbag 52 is mounted within the guide cylinder 51, the driven bevel block 53 is slidably mounted within the guide cylinder 51, the driving bevel block 54 is disposed on the driven bevel block 53 and is connected to the drive gear 24, the air inlet 511 is provided on the guide cylinder 51, and the air supply pipe 55 passes through the fixed tube 11 and is connected to the vibration assembly 4, and is connected to the airbag 52 and the mounting post 32.
[0048] Specifically, when the driving gear 24 rotates, it drives the active inclined block 54 connected to it to rotate. When the active inclined block 54 rotates, it presses down the driven inclined block 53. After being pressed down, the driven inclined block 53 compresses the air bag 52 set in the guide cylinder 51. The active inclined block 54 continues to rotate, and the driven inclined block 53 is reset under the elasticity of the air bag 52. The air bag 52 pumps gas from the air pipe 55 into the mixing barrel 2 during continuous compression to dry the powder.
[0049] Furthermore, an air path 321 is defined in the mounting column 32 and a plurality of air injection ports 322 corresponding to the spiral feeding plate 33 are defined.
[0050] Specifically, the gas pipe 55 inputs gas into the gas path 321 and blows gas evenly toward the powder evenly distributed on the spiral feeding plate 33 through the spirally distributed air jets 322 provided on the mounting column 32 to help dry the powder.
[0051] In one embodiment, a guide groove 512 is formed on the guide cylinder 51 , and a guide block 531 adapted to the guide groove 512 is fixedly mounted on the driven bevel block 53 .
[0052] It is understandable that the driven bevel block 53 can slide in the up and down directions in the guide cylinder 51 under the limiting action of the guide block 531 and the guide groove 512 .
[0053] In one embodiment, a ratchet 541 is provided on the active bevel block 54, a fixed plate 241 is fixedly installed on the driving gear 24, a rotating shaft 242 is fixedly installed on the driving gear 24, a pawl 243 is rotatably mounted on the rotating shaft 242, and an elastic sheet 244 adapted to the pawl 243 is fixedly installed on the fixed plate 241.
[0054] Specifically, during the mixing and drying process, the output end of the servo motor 23 rotates clockwise (from a top-down perspective). When the driving gear 24 rotates clockwise, the elastic sheet 244 lifts the pawl 243 mounted on the rotating shaft 242. When the pawl 243 rotates, it abuts against the ratchet 541, driving the active bevel block 54 to rotate clockwise, thereby squeezing the airbag 52. When the servo motor 23 reverses, the pawl 243 is pressed under the action of the ratchet 541, and the elastic sheet 244 is squeezed. The pawl 243 gives way and does not drive the active bevel block 54 to rotate.
[0055] See also Figure 7 The gas delivery pipe 55 is sheathed with a metal heating net 61 , and the metal heating net 61 is sheathed with a heat-resistance sleeve 6 .
[0056] Specifically, the metal heating mesh 61 can heat the gas in the gas pipe 55, and the heat-resistance sleeve 6 can avoid heat waste.
[0057] Please combine Figure 4 For reference, in an exemplary embodiment, a cleaning assembly 7 is disposed within the mixing barrel 2. The cleaning assembly 7 may include a mounting sleeve 71 and a cleaning arm 72. The mounting sleeve 71 is sleeved onto the connecting post 34, passes through the mixing barrel 2, and is fixedly connected to the guide plate 41. The cleaning arm 72 is fixedly mounted on the mounting sleeve 71 and is arranged in an L-shape.
[0058] Specifically, when cleaning is required, the servo motor 23 reverses, and the driving block 431 abuts against the movable disk 42 in the opposite direction. The movable disk 42 drives the guide disk 41 to rotate, and the mounting sleeve 71 fixed on the guide disk 41 will rotate accordingly, thereby driving the cleaning arm 72 to rotate and clean the inner arm of the mixing barrel 2.
[0059] Furthermore, the contact friction between the mounting sleeve 71 and the mixing barrel 2 is greater than the contact friction between the driving block 431 and the movable disk 42 , and the other surface of the driving block 431 is arranged perpendicular to the movable disk 42 .
[0060] It is understandable that when the servo motor 23 rotates forward, the guide plate 41 will not rotate due to the greater friction force, thereby vibrating. When the servo motor 23 rotates reversely, the vertical surface of the driving block 431 can abut the movable plate 42 and drive it to rotate.
[0061] Among them, the cleaning arm 72 is set close to the inner wall of the mixing barrel 2, and the side of the cleaning arm 72 close to the mixing barrel 2 is provided with bristles. The bristles can effectively remove dirt and sediment on the inner wall of the mixing barrel 2, and can increase the contact area with the inner wall of the mixing barrel 2, thereby improving the cleaning efficiency.
[0062] The powder mixing device with a drying function proposed in the embodiment of the present application uses a vibration component 4 and a feeding component 3 to gradually transfer the powder from the feeding port 21 to the discharging port 22, and the powder is evenly turned over by vibration, so that the powder can be evenly dried. The heated air is evenly blown onto the powder by the jet component 5 to accelerate the drying process. The wall of the mixing barrel 2 after mixing is cleaned by the cleaning component 7. Through the cooperation of the above-mentioned structures, not only the drying rate and the uniformity of drying can be improved, but also the feeding speed can be controlled by vibration, and the mixing barrel 2 can be automatically cleaned after mixing, saving labor costs.
[0063] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
