[0032] The specific setup and function of the conveying device 2 and the shielding device 3 will be described in detail below.

[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the conveying device 2 includes a guide pipe 201, one end of which is fixedly connected to the airflow pulverizer 1, and a feeding pipe 202 is fixedly connected to the other end of the guide pipe 201. The feeding pipe 202 has a feeding port 211 on its arc surface. An L-shaped fixing plate 203 is fixedly connected to one side of the feeding pipe 202. A drive motor 204 is fixedly connected to the short arm end of the L-shaped fixing plate 203. A T-shaped block 205 is fixedly connected to the output end of the drive motor 204. The arc surface of the T-shaped block 205 is rotatably connected to the feeding pipe 202. A round rod 206 is fixedly connected to one end of the T-shaped block 205, and a conveying spiral blade 207 is fixedly connected to the arc surface of the round rod 206. This achieves the effect that the drive motor 204 starts and drives the T-shaped block 205 to rotate, the T-shaped block 205 drives the round rod 206 to rotate, and the round rod 206 drives the conveying spiral blade 207. A limiting plate 210 is fixedly connected to the arc surface of the feed tube 201, and one end of the limiting plate 210 is fixedly connected to the feed tube 202. This achieves the effect of the limiting plate 210 preventing deformation of the feed tube 202 during long-term use. A ball bearing 209 is fixedly connected to one side of the feed tube 202. This achieves the effect of fixing the ball bearing 209 to the feed tube 202. A round block 208 is fixedly connected to the inner side of the ball bearing 209, and one end of the round block 208 is fixedly connected to the round rod 206. This achieves the effect of fixing the round block 208 to the ball bearing 209, preventing deformation of the round rod 206 during rotation.

[0034] Reference Figure 4 As shown, in this embodiment: the shielding device 3 includes an arc-shaped plate 31, the inner side of which is fixedly connected to the feeding pipe 202, and two guide rods 32 are fixedly connected to one side of the arc-shaped plate 31. This achieves the effect of fixing the guide rods 32 to the arc-shaped plate 31. A limiting plate 37 is fixedly connected to one end of the two guide rods 32. This achieves the effect of preventing the guide rods 32 from deforming during use. A guide block 33 is slidably connected to the arc surface of the guide rod 32, and a shielding cylinder 34 is fixedly connected to the side of the two guide blocks 33 that are close to each other. This achieves the effect of the shielding cylinder 34 moving to drive the guide block 33 to slide on the guide rod 32. An L-shaped plate 35 is fixedly connected to one end of the shielding cylinder 34. This achieves the effect of the L-shaped plate 35 being stressed to facilitate the movement of the shielding cylinder 34. A U-shaped anti-slip pad 36, made of rubber, is fixedly connected to the outside of the L-shaped plate 35. This achieves the effect of the U-shaped anti-slip pad 36 increasing friction.

[0035] Working principle: When it is necessary to prevent blockage of the micro / nano silver powder after it has been pulverized and discharged from the feeding port 211, the operator first adds the micro / nano silver powder to be pulverized into the air jet mill 1 for pulverization. The pulverized micro / nano silver powder is then discharged from the air jet mill 1 into the guide pipe 201. At this time, the drive motor 204 is started. The output end of the drive motor 204 drives the T-shaped block 205 to rotate, which in turn drives the round rod 206 to rotate, thus driving the conveying spiral blades 207 to propel the micro / nano silver powder from the guide pipe 201 into the feeding pipe 202. Nano-silver powder is discharged from the feeding port 211 on the feeding pipe 202 to achieve feeding effect, effectively avoiding the phenomenon of agglomeration and clumping of micro-nano silver powder. The rotation of the round rod 206 simultaneously drives the round block 208 to rotate within the ball bearing 209, thereby preventing the round rod 206 from deforming during rotation. Through the conveying device 2, the problem of clogs caused by the small particle size of micro-nano silver powder in traditional micro-nano silver powder crushing and feeding devices is solved.

[0036] By using the shielding device 3, when it is necessary to prevent dust, insects, and debris from entering the feeding pipe 202 after feeding is stopped, the operator first applies a pushing force to the U-shaped anti-slip pad 36 towards the feeding pipe 202. The pushing force is transmitted to the L-shaped plate 35, causing the shielding cylinder 34 to move towards the feeding pipe 202. At this time, the guide block 33 slides on the guide rod 32 until the shielding cylinder 34 completely blocks the feeding port 211 on the feeding pipe 202. Then the applied pushing force can be stopped. By using the shielding device 3, the problem of dust, insects, and debris easily entering the feeding pipe 202 from the feeding port 211 after feeding is stopped in traditional micro-nano silver powder crushing and feeding devices is solved.
