[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The particle retarding mechanism is used to decelerate the diamond powder particles, reduce the initial velocity of the diamond powder particles when they fall from the bottom opening of the blanking shell, thereby reducing the loss caused by the splashing of the electroplating liquid surface, and disperse the diamond powder particles through the particle dispersing mechanism.

[0019] 2. When the diamond micro-powder particles rotate to the bottom of the adsorption ring, the arc-surface baffle blocks the connecting hole at the bottom of the adsorption ring, thereby blocking the negative pressure adsorption below the adsorption ring, so that the diamond micro-powder particles lose the negative pressure adsorption force and fall into the electroplating solution, so that the diamond micro-powder particles move to the bottom of the adsorption ring and fall downward from a static state, thereby reducing the initial velocity of the diamond micro-powder particles when entering the electroplating solution and slowing down the falling trend, reducing the splashing of the electroplating solution surface during the entry of the diamond micro-powder particles, and preventing the electroplating solution from splashing and causing loss.

[0020] 3. The internal channel of the blanking shell is blocked by the rotating roller, and the rotating roller is continuously rotated 180 degrees intermittently, so that the two receiving grooves transfer the diamond micro-powder particles above the rotating roller downward in turn, thereby limiting the movement efficiency of the diamond micro-powder particles inside the blanking shell, preventing the number of diamond micro-powder particles from being greater than the adsorption area of ​​the annular filter cloth, and causing some diamond micro-powder particles to directly enter the electroplating solution without being slowed down, thereby improving the regularity and stability of the diamond micro-powder particles falling.

[0021] 4. The rotating ring is limited in rotation by the limiting roller, so that the annular screen rotates inside the upper sand cylinder and the diamond powder particles are screened by rotation, so that the diamond powder particles that meet the particle size requirements pass through the annular screen and enter the first guide shell along the connection between the upper sand cylinder and the first guide shell, preventing the diamond powder particles with larger particle size from being electroplated on the metal wire and affecting the uniformity of the metal wire surface, thereby improving the smoothness of the diamond wire surface.

In order to reduce the falling distance, the staff pours the diamond powder particles into the feed hopper 3, and the diamond powder particles in the feed hopper 3 are transported to the upper sand cylinder 2 through the action of the connecting feeding mechanism, and enter the first guide shell 4 along the connection between the upper sand cylinder 2 and the first guide shell 4. The diamond powder particles enter the second guide shell 5 from the first guide shell 4 through the action of the telescopic connecting mechanism, and when moving downward in the second guide shell 5, the diamond powder particles in the second guide shell 5 are dispersed through the action of the particle dispersion mechanism, and enter the blanking shell 6 after dispersion. When the diamond micro-powder particles move toward the surface of the electroplating liquid along the opening at the bottom of the blanking shell 6, the diamond micro-powder particles are decelerated by the particle deceleration mechanism, reducing the initial velocity of the diamond micro-powder particles when falling from the bottom opening of the blanking shell 6, thereby reducing the loss caused by splashing of the electroplating liquid surface, and the diamond micro-powder particles are dispersed by the particle dispersion mechanism, and the diamond micro-powder particles can be evenly dispersed in the electroplating liquid in cooperation with the horizontal displacement mechanism, thereby improving the uniformity of the diamond micro-powder particles in the electroplating liquid and ensuring the uniformity of the diamond micro-powder particles on the surface of the metal wire during the electroplating process.

The staff pours the diamond micro-powder particles into the feed hopper 3, and the diamond micro-powder particles in the feed hopper 3 are transported to the upper sand cylinder 2 through the connecting feeding mechanism, and enter the first guide shell 4 along the connecting point between the upper sand cylinder 2 and the first guide shell 4, and the diamond micro-powder particles enter the second guide shell 4 from the first guide shell 4 through the telescopic connecting mechanism. The diamond powder particles are dispersed in the second guide housing 5 and move downward in the second guide housing 5 through the particle dispersion mechanism, and enter the blanking housing 6 after dispersion. When the diamond powder particles move toward the surface of the electroplating liquid along the opening at the bottom of the blanking housing 6, the diamond powder particles are decelerated by the particle deceleration mechanism to reduce the initial velocity of the diamond powder particles when falling from the bottom opening of the blanking housing 6, thereby reducing the loss caused by splashing of the electroplating liquid surface, and the diamond powder particles are dispersed by the particle dispersion mechanism, and the diamond powder particles can be evenly dispersed in the electroplating liquid with the help of the horizontal displacement mechanism, thereby improving the uniformity of the diamond powder particles in the electroplating liquid and ensuring the uniformity of the diamond powder particles on the surface of the metal wire during the electroplating process.
