Description

Technical Field

[0001] This application relates to the field of air jet mill technology, and more specifically, to a feeding device for an air jet mill. Background Technology

[0002] An air jet mill is a device that uses high-speed airflow to pulverize materials into ultrafine powder. Its working principle is to generate high-speed airflow by compressing air or inert gas, so that the material particles collide and rub against each other in the airflow, thereby achieving pulverization. However, in actual production, it has been found that the material tends to adhere to the inner wall of the feed pipe during the feeding process. After the adhered material accumulates, its volume increases, which can easily lead to blockage of the feed pipe, thus having a defect. Utility Model Content

The motor 9 is mounted on the mounting frame 2 and drives the cam 10 to rotate through an output shaft. The vibrating assembly 8 includes a push plate 11, a wedge plate 12, an impact block 13, and a first elastic element 14. The push plate 11 is movably inserted through the mounting frame 2. The wedge plate 12 is disposed between the push plate 11 and the impact block 13. The wedge plate 12 is located between the mounting frame 2 and the feeding pipe 5. The wedge plate 12 cooperates with the cam 10. The impact block 13 abuts against the feeding pipe 5. The first elastic element 14 is disposed between the wedge plate 12 and the mounting frame 2.

[0029] In use, the control valve 6 is opened, and the material inside the air jet mill body 1 is discharged through the feed pipe 5. The motor 9 is started, and the motor 9 drives the cam 10 to rotate through the output shaft. With the cooperation of the cam 10 and the wedge plate 12, the wedge plate 12 drives the push plate 11 and the impact block 13 to move away from the feed pipe 5. Under the action of the rebound force of the first elastic element 14, the wedge plate 12 drives the push plate 11 and the impact block 13 to move closer to the feed pipe 5 and impact the feed pipe 5, thereby reducing the adhesion and accumulation of material in the feed pipe 5 and ensuring smooth feeding.

[0030] In this embodiment, the vibrating material assembly 8 also includes a support frame 15, which is mounted on the mounting frame 2. The push plate 11 is movably inserted through the support frame 15, and the support frame 15 supports the push plate 11, thereby improving the stability of the push plate 11.

The limiting sleeve 16 is located on the side of the mounting frame 2 away from the wedge plate 12.

[0032] In this embodiment, the vibrating material assembly 8 also includes a second elastic element 17, which is disposed between the limiting sleeve 16 and the support frame 15. The second elastic element 17 is used to ensure that the push plate 11 receives sufficient rebound force.

[0033] In this embodiment, multiple first elastic elements 14 and multiple second elastic elements 17 are provided. The provision of multiple first elastic elements 14 and multiple second elastic elements 17 can improve the stability of the push plate 11 operation and ensure that the push plate 11 receives sufficient rebound force, so that the impact block 13 can continuously impact the feed tube 5.

[0034] In this embodiment, both the first elastic element 14 and the second elastic element 17 are springs. Springs are common standard parts that are easy to purchase and install.

[0035] In this embodiment, two sets of vibrating mechanisms 3 are provided. The two sets of vibrating mechanisms 3 are arranged opposite each other on both sides of the air jet mill body 1, and impact the feed pipe 5 from different directions, which can facilitate the dislodging of the material in the feed pipe 5.
