[0021] according to Figure 1 — Figure 4 The device is an automatic screening and collection device for ceramic powder, comprising a screening box 1, two feed ports 2 on the top of the screening box, a dustproof door 3 on the front of the screening box, a door handle 4 on the front of the dustproof door 3, and a dustproof door connected to the screening box 1 shell through a hinge 5; a screen 6 is provided inside the screening box, and the screen is divided into two layers, upper and lower, corresponding to two different levels of aperture sizes, and the aperture of the screen decreases from top to bottom. The collecting tray 15 is located at the bottom layer and collects the powder filtered by the bottom layer of the screen; a screw 9 is provided above the middle position of the screen 6 and the collecting tray 15, and the screw passes through the screen 6 and the collecting tray 15 and is connected to the cylinder 10 below it, and the cylinder 10 The inner diameter has an internal thread; the left side of the screen 6 and the collecting tray 15 each has a discharge port 7, the discharge port 7 is connected to the collecting box 8, and the discharge port 7 extends into the collecting box 8; the collecting box 8 is placed on a support plate 11, and the support plate 11 is fixed to the left support frame 12; there is a support frame 12 on the right side of the inside of the screening box 1, and there is a spring 16 and a support rod 17 on the support frame, one end of the spring is fixed to the support frame 12, and the other end is suspended in the air, one end of the support rod 17 is fixed to the support frame, and the other end has a fixing nail 18; the screen 6 and the collecting tray 15 are connected to the bottom vibration plate 13 through the cylinder 10, and the vibration plate 13 is connected to the drive motor 14.

[0022] Specifically, such as Figure 1 As shown, there are two feed ports 2 on the top of the screening box 1, and a cover 19 is provided on the top of the feed port 2. The cover is closed after the feeding is completed to prevent dust in the external environment from entering the screening box 1 and dust caused by mechanical vibration from escaping.

[0023] Specifically, such as Figure 2 As shown, the two feed ports 2 on the top of the screening box 1 are located on both sides of the middle position of the screen 6 and the collecting plate 15, and materials can be fed to both ends of the screen 6 respectively; the mesh areas of the upper and lower layers of screen 6 increase from top to bottom, effectively preventing the powder passing through the upper layer of screen 6 from being scattered to the external area.

[0024] Specifically, such as Figure 2 As shown, the screen 6 is movably connected to the support cylinder 10 by screws 9, and the screen 6 can be replaced according to the particle size of the ceramic powder screening; there is a gap between the screws 9, the screen 6, and the support cylinder 10, and the gap meets the space required for the left and right ends of the screen 6 to tilt.

[0025] Specifically, such as Figure 2 and Figure 4 As shown, the length of the spring 16 after stretching can be connected to the fixing nail 18 at the top of the support rod 17. The length of the support rod 17 is not less than the distance from its top to the right side of the screen 6. After the support rod 17 is lifted under the tension of the spring 16, the bottom end touches the screen 6 and the right side of the collection tray 15 to lift it upward, and the powder in the screen 6 and the collection tray 15 is poured into the collection box 8 on the left.

[0026] Specifically, such as Figure 3 As shown, the collecting box 8 has a cover 19 on the top and a hole 20 on the right side. The size of the hole 17 satisfies the space required for the tilting of the discharge port 7.

[0027] The operator pours the ceramic powder to be screened into the screening box 1 through the feed port 2. The ceramic powder enters the upper screen 6. The motor 14 drives the vibrating plate 13 to vibrate. The vibrating plate 13 drives the screen 6 to vibrate through the supporting cylinder 10. The powder with large particle size remains in the screen 6, and the powder with small particle size passes through the upper screen 6 and enters the lower screen 6. The screening continues under the vibration of the vibrating plate 13. The powder with even smaller particle size enters the next collection plate 15. After some powder is gathered in the screen 6 and the collection plate 15, the bottom end of the spring 16 is connected to the fixing nail 18 at the bottom end of the support rod 17, as shown in FIG. Figure 4 As shown, after the support rod 17 is lifted under the tension of the spring 16, the bottom end touches the right side of the screen 6 and the collection tray 15 to lift it upward, and the powder in the screen 6 and the collection tray 15 is poured into the left collection box 8, completing one round of screening and collection. Disconnect the connection between the spring 16 and the support rod 17, the screen 6 and the collection tray 15 return to a parallel state, continue to add the ceramic powder to be screened, and complete the screening and collection. After the left collection box 8 is full, stop feeding and screening, the operator opens the dustproof door 3, and takes out the powder in the collection box. Then put the empty collection box 8 back into the screening box, and start a new round of screening until all the powder is screened.
