Abstract

This utility model discloses a shaping device for ultrafine powder particles, including a fixed support. A shaping box is fixedly installed at the top opening of the fixed support by four fixed corner plates. A controller is installed on the front of the shaping box. A stirring assembly is arranged inside the shaping box. The stirring assembly includes a stirring shaft, and the two ends of the stirring shaft are rotatably connected to the two ends of the shaping box, respectively. A first connecting rod and a second connecting rod are fixedly connected to the surface of the stirring shaft. This utility model, by setting up a stirring assembly composed of a stirring shaft, a feeding plate, a tipping hopper, and spiral blades, allows the feeding plate to stir most of the powder particles in the shaping box when it rotates.

This multi-dimensional stirring structure allows for sufficient collision and grinding between powder particles, which is beneficial to improving the shaping effect.

Description

Technical Field

[0001] This utility model relates to the field of powder shaping technology, specifically to a shaping device for ultrafine powder particles. Background Technology

[0002] Naturally obtained powder particles often possess numerous inherent defects that hinder production and application. In terms of shape, natural powder particles vary widely, often exhibiting irregular forms such as angular or flaky shapes. This irregularity leads to increased friction and cohesion between particles, resulting in extremely poor flowability. Regarding particle size distribution, natural powder particles typically exhibit a wide range of sizes, with a mixture of large and small particles. This uneven particle size distribution affects the powder's bulk density and porosity. To improve the properties of powder particles and meet the application requirements of various fields, shaping devices are often used to reshape them. Stirred mills, as one method of powder particle shaping, utilize a stirrer to move the powder particles, causing them to collide and grind against each other, thereby achieving a shaping effect.

[0003] However, some existing stirred mill shaping devices cannot agitate the powder particles near the inner wall of the device when shaping powder particles, which is not conducive to improving the shaping effect.

[0004] Therefore, it is necessary to invent a shaping device for ultrafine powder particles to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a shaping device for ultrafine powder particles to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaping device for ultrafine powder particles, comprising a fixed support, a shaping box fixedly installed at the top opening of the fixed support by four fixed corner plates, a controller installed on the front of the shaping box, a stirring assembly inside the shaping box, the stirring assembly comprising a stirring shaft, the two ends of the stirring shaft being rotatably connected to the two ends of the shaping box respectively, a first connecting rod and a second connecting rod fixedly connected to the surface of the stirring shaft, a material feeding plate fixedly connected to the end of the first connecting rod, a material turning hopper fixedly connected to the end of the second connecting rod, the edge of the material shoveling port of the material turning hopper being in contact with the inner wall of the shaping box, and a spiral blade sleeved on the outside of the stirring shaft, the spiral blade being fixedly connected to the first connecting rod.

[0007] The multi-dimensional stirring structure, consisting of a feeding plate, spiral blades, and a tipping hopper, enables thorough stirring of powder particles in different areas within the shaping box, thereby improving the shaping effect.

[0008] Preferably, the shaping box has a U-shaped cross-section, and a feeding pipe is fixedly connected to the center of the bottom of the shaping box, with a valve installed in the middle of the feeding pipe.

[0009] The U-shaped cross-section design facilitates the accumulation of powder particles towards the bottom center, and, in conjunction with the feed pipe and valves, makes it easy to discharge the shaped powder.

[0010] Preferably, a speed reducer and a drive motor are installed on one side of the top of the fixed bracket, and the drive motor is electrically connected to the controller.

[0011] The controller controls the start and stop of the drive motor, and the reducer adjusts the stirring speed to meet the shaping needs of different powder particles, thereby improving the automation level of the equipment.

[0012] Preferably, the output shaft of the drive motor is connected to the input shaft of the reducer, and one end of the stirring shaft extends to the outside of the shaping box and is connected to the output shaft of the reducer.

[0013] Power transmission and speed regulation are achieved through a speed reducer, ensuring stable rotation of the stirring shaft while reducing the load on the drive motor and extending the service life of the equipment.

[0014] Preferably, a sealing cover is hinged at the top opening of the shaping box, and a connector is installed on each of the top two sides of the sealing cover.

[0015] The sealing cover is used to seal the opening at the top of the shaping box to prevent powder leakage during the shaping process.

[0016] Preferably, each side of the shaping box is provided with an electric push rod, and both electric push rods are electrically connected to the controller.

[0017] The electric push rod is controlled by the controller to extend and retract, which can drive the sealing cover to open and close, realizing the automatic opening and closing of the feed inlet.

[0018] Preferably, the bottom ends of the two electric push rods are respectively hinged to two of the fixed angle plates, and the working ends of the two electric push rods are respectively hinged to the two connecting pieces.

[0019] The hinged structure allows the electric actuator to flexibly open and close the sealing cover, adapting to different mechanical requirements at different angles and ensuring smooth and reliable operation.

[0020] Preferably, the spiral blades are positioned close to the surface of the stirring shaft, and there is a gap between the spiral blades and the surface of the stirring shaft so that they do not directly contact each other.

[0021] The spiral blades are designed to be close to the surface of the stirring shaft while leaving gaps to avoid direct contact. When they rotate, the spiral structure agitates the powder particles near the shaft center area, while also avoiding dead zones caused by structural obstruction.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. By setting up a stirring assembly consisting of a stirring shaft, a feeding plate, a tipping hopper, and spiral blades, the feeding plate can stir most of the powder particles in the shaping box when it rotates, the spiral blades can stir the powder particles near the center of the shaft when they rotate, and the tipping hopper can scoop up the powder particles attached to the box wall and put them back into the mainstream powder when it rotates. This multi-dimensional stirring structure allows the powder particles to collide and grind fully, which is beneficial to improving the shaping effect.

[0024] 2. By installing electric push rods on both sides of the shaping box, when the controller controls the electric push rods to extend or retract, it can drive the sealing cover to open and close, thus realizing the automatic opening and closing of the feed inlet. Attached Figure Description

The two ends of the stirring shaft 6 are rotatably connected to the two ends of the shaping box 3, respectively. A first connecting rod 7 and a second connecting rod 17 are fixedly connected to the surface of the stirring shaft 6. A material feeding plate 8 is fixedly connected to the end of the first connecting rod 7. A tipping hopper 9 is fixedly connected to the end of the second connecting rod 17. The edge of the material feeding port of the tipping hopper 9 is in contact with the inner wall of the shaping box 3. A spiral blade 10 is sleeved on the outside of the stirring shaft 6. The spiral blade 10 is fixedly connected to the first connecting rod 7.

[0035] In one aspect of this embodiment, the shaping box 3 has a U-shaped cross-section. A feeding pipe 11 is fixedly connected to the center of the bottom of the shaping box 3. A valve is installed in the middle of the feeding pipe 11. A reducer 12 and a drive motor 13 are installed on one side of the top of the fixed bracket 1. The drive motor 13 is electrically connected to the controller 4. The output shaft of the drive motor 13 is drivenly connected to the input shaft of the reducer 12. One end of the stirring shaft 6 extends to the outside of the shaping box 3 and is drivenly connected to the output shaft of the reducer 12. A sealing cover plate 14 is hinged at the top opening of the shaping box 3. A connector 15 is installed on each side of the top of the sealing cover plate 14. An electric push rod 16 is provided on each side of the shaping box 3. Both electric push rods 16 are electrically connected to the controller 4. The bottom ends of the two electric push rods 16 are respectively hinged to two fixed angle plates 2. The working ends of the two electric push rods 16 are respectively hinged to two connectors 15. The spiral blade 10 is set close to the surface of the stirring shaft 6. The spiral blade 10 and the surface of the stirring shaft 6 are left with a gap and do not directly contact each other.

[0036] The controller 4, reducer 12, drive motor 13 and electric push rod 16 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0037] Working principle of this utility model:

[0038] Refer to the instruction manual appendix Figure 1-6 When using this utility model, firstly, start the electric push rod 16 through the controller 4. The working end of the electric push rod 16 pushes the sealing cover 14 upward to open it. After a certain amount of powder to be processed is put into the shaping box 3, the sealing cover 14 is closed.

[0039] Then, the drive motor 13 is started by the controller 4. The drive motor 13 drives the stirring shaft 6 to rotate through the reducer 12, so that the stirring component 5 stirs the powder. At this time, the material feeding plate 8 rotates with the stirring shaft 6 to stir most of the powder particles in the shaping box 3. The spiral blade 10 rotates with the stirring shaft 6 to stir the powder particles near the shaft center area. The shovel port of the tipping hopper 9 is close to the inner wall of the shaping box 3. By rotating, the powder particles attached to the box wall are shoveled up and put back into the mainstream powder. This multi-dimensional stirring structure makes the powder particles collide and grind fully, which is beneficial to improving the shaping effect.

[0040] After the shaping is completed, open the valve of the feed pipe 11. At this time, the stirring component 5 can maintain the continuous stirring of the powder, thereby promoting the powder to be discharged out through the feed pipe 11.
