[0002] With the development of science and technology and the deepening of industrial applications, solid powder materials have been widely used in many fields, especially in the fields of pharmaceuticals, food, and chemicals. However, in the process of processing solid powder materials, it is necessary to ensure the accuracy and stability of micro-feeding. Although the traditional feeding device can achieve the purpose of micro-feeding when in use, there is no anti-blocking structure in the feeding device. During the feeding process, the powder is easy to block the feeding port, which in turn affects the normal feeding. In addition, the existing feeding device also has the limitations of low feeding accuracy and poor feeding uniformity, which cannot meet the high-precision and high-efficiency production requirements. At the same time, in the feeding device, the material bottle is directly connected to the device body, and the connection port on the device body can only be used to install and use the material bottle with the same type of bottle mouth, which has poor adaptability.

Detailed implementation manner

[0019] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0020] As Figures 1-5 shown, a device for micro blanking of solid powder includes a blanking bin 1, a connecting frame 2 is arranged on the blanking bin 1, a protective cover 3 is installed on the connecting frame 2, a connection port 17 is arranged on the connecting frame 2, a lifting mechanism is arranged inside the blanking bin 1 and the protective cover 3, and a stirring mechanism is arranged inside the blanking bin 1 and the protective cover 3. A storage structure 4 is installed on the connecting frame 2, and the storage structure 4 includes a material bottle 401 and an adapter 403. The material bottle 401 is connected to the adapter 403. The storage structure 4 further includes a bottle mouth joint 402, a thread groove 404 and an adapter joint 405. The bottle mouth joint 402 is fixed at the end of the material bottle 401. The thread groove 404 is arranged on the adapter 403, and the thread groove 404 is in threaded connection with the bottle mouth joint 402. The adapter joint 405 is fixed on the adapter 403, and the adapter joint 405 is connected in the connection port 17.

[0021] By setting the storage structure 4, the material bottle 401 is connected to the connection port 17 through the adapter 403, and the material bottle 401 with different diameters can be replaced according to needs, improving the use adaptability.

[0022] When using the blanking device, the material bottle 401 is connected to the adapter 403 through the bottle mouth joint 402 and the thread groove 404. The adapter 403 is installed at the connection port 17 through the adapter joint 405. There is solid powder material inside the material bottle 401. The powder material enters the blanking bin 1 through the connection port 17 at the adapter 403. Finally, the solid powder is discharged from the bottom bin opening of the blanking bin 1, thus achieving the purpose of micro blanking. During this process, the stirring mechanism operates to push and measure the material, ensuring the accuracy of blanking. The lifting mechanism can adjust the gap at the bin opening of the blanking bin 1, thereby achieving the accuracy control of blanking. When needed, the material bottle 401 can be disassembled and replaced, which is convenient for replacing material bottles 401 with different diameters for use, and has high adaptability in use.

[0023] Through the above implementation scheme, the stirring mechanism is composed of a rotating frame 5, a stirring motor 10, a driving gear 11, a driven gear 12, and a stirring frame 13. The rotating frame 5 is fixedly connected to the driven gear 12, and the rotating frame 5 is installed through the part where the blanking bin 1, the protective cover 3, and the connecting frame 2 are connected. The stirring motor 10 is installed inside the protective cover 3. The driving gear 11 is connected to the stirring motor 10, and the driving gear 11 is meshed with the driven gear 12. The stirring frame 13 is fixed at the lower end of the rotating frame 5. There is a bearing 14 on the connecting frame 2, and the rotating frame 5 is installed inside the bearing 14. There is a first snap ring 15 inside the blanking bin 1, and a second snap ring 16 is provided on the connecting frame 2. Through the set stirring mechanism, the stirring mechanism is composed of a stirring motor 10, a driving gear 11, a driven gear 12, a rotating frame 5, and a stirring frame 13. The stirring motor 10 drives the stirring frame 13 to operate, thereby realizing the pushing and measuring of the powder. The rotation angle and speed can be controlled, thus achieving the purpose of accurate micro blanking.

[0024] When using the stirring mechanism, after starting the stirring motor 10, the stirring motor 10 drives the driving gear 11 to rotate, thereby driving the rotating frame 5 to rotate inside the bearing 14 through the driven gear 12, and then driving the stirring frame 13 to rotate. The stirring frame 13 pushes the powder material, and at the same time, the stirring mechanism can achieve the effect of measurement, ensuring the accuracy of micro blanking. During this process, the rotation of the rotating frame 5 does not affect the stability of the lifting mechanism, and due to the limiting effect of the first snap ring 15 and the second snap ring 16, the bearing 14 is fixedly arranged, ensuring the relative stability of the rotating frame 5.

[0025] Through the above embodiments, the lifting mechanism includes a lifting motor 6, an eccentric cam 7, a reset assembly 8, and a lifting rod 9. The lifting motor 6 is installed inside the protective cover 3, the eccentric cam 7 is installed on the lifting motor 6, the reset assembly 8 is connected to the lifting rod 9, and the lower end of the reset assembly 8 is located inside the rotating frame 5. The reset assembly 8 includes an internal thread 801, a limiting block 802, a lifting rod 803, a ball 804, an abutting block 805, a reset spring 806, and an abutting plate 807. The internal thread 801 is provided inside the rotating frame 5. The limiting block 802 is fixedly connected to the lifting rod 803, and the lifting rod 803 passes through the driven gear 12 at the upper end of the rotating frame 5. The ball 804 is installed on the lifting rod 803 and is in contact with the eccentric cam 7. The abutting block 805 is installed inside the rotating frame 5 through the internal thread 801. The reset spring 806 and the abutting plate 807 are fixedly connected, and the upper end of the reset spring 806 is connected to the internal thread 801. The abutting plate 807 abuts against the abutting block 805. With the lifting mechanism, which consists of a lifting motor 6, an eccentric cam 7, a reset assembly 8, and a lifting rod 9, the height of the lifting rod 9 can be controlled by the lifting motor 6, the gap between the lifting rod 9 and the bottom opening of the blanking bin 1 can be changed, and thus the blanking accuracy can be controlled.

[0026] When using the lifting mechanism, in the initial stage, the abutting plate 807 contacts the abutting block 805. Due to the action of the reset spring 806, the limiting block 802 and the lifting rod 803 tend to move upward, causing the ball 804 to contact the eccentric cam 7. When the height of the lifting rod 9 needs to be adjusted, after starting the lifting motor 6, the lifting motor 6 drives the eccentric cam 7 to rotate. Under the action of the reset spring 806, the ball 804 is always in contact with the eccentric cam 7, thereby causing the limiting block 802 and the lifting rod 803 to move. The lifting rod 803 drives the lifting rod 9 to move up and down, thereby changing the gap between the lifting rod 9 and the lower opening of the blanking bin 1, and the blanking accuracy can be controlled. When needed, the abutting block 805 at the internal thread 801 can be rotated, thereby changing the compression degree of the reset spring 806 and adjusting the reset force, making it more flexible and adaptable in use.
