A vibrator 15 is fixedly provided at the side of the bottom end of the storage bin 5 to avoid jamming during feeding and the situation where the powder cannot fall.

[0032] In order to achieve automatic feeding and control of the feeding amount. For details, refer to Figure 2 and Figure 3 , a bracket 6 for supporting the processing table 1 and the storage bin 5 is provided at the lower part of the processing table 1. A feeding control module 7 is provided between the storage bin 5 and the loading tray 3. The feeding control module 7 includes a feeding tube 71 fixedly provided on the bracket 6 at the tail end of the processing table 1, and the loading tray 3 can enter and exit from the side of the feeding tube 71. It is convenient for loading during subsequent production. A temporary storage tube 72 is fixedly provided on the bracket 6 above the feeding tube 71 and communicated with the feeding tube 71.

[0033] Toothed fans 74 are fixedly provided on the outer circles of the rotating parts of the iris mechanisms 73. Gears 75 are meshed on the sides of the toothed fans 74. Second bidirectional motors 76 for respectively driving the gears 75 to rotate are fixedly provided on the bracket 6. Control the second bidirectional motor 76 to work, so as to drive the corresponding toothed fan 74 to rotate through the gear 75. Thus, by controlling the corresponding iris mechanism 73, the size of the feeding channel is controlled, and automatic feeding and control of the feeding amount of the powder are realized. A pressure sensor 77 is fixedly provided on the processing table 1 below the feeding tube 71. Detect the weight of the powder in the loading tray 3 to control the feeding amount.

[0034] Usage method of the automatic feeding device for powder materials in the preparation of high-purity alumina ceramics of the present utility model: First, open the end cover 14, and add the powder materials into the storage bin 5 from the feeding port 13. Drive the screw rod 9 to rotate through the first bidirectional motor 11, so as to move the feeding tray 3 to directly below the blanking cylinder 71. Control the second motor 46 to work, drive the winding rod 45 to rotate, and move the sealing cover 42 to the limit position through the pulling rope 47. Control the upper second bidirectional motor 76 to work, drive the corresponding tooth fan 74 to rotate through the gear 75, and operate the iris mechanism 73 above, so as to open the channel between the discharge port 12 and the temporary storage cylinder 72. The divided materials in the storage bin 5 enter the temporary storage bin through the discharge port 12. After a period of time, reverse the second bidirectional motor 76 to close the channel. During this process, control the vibrator 15 to work to avoid material jamming and the situation where the powder materials cannot fall during blanking.

[0035] When feeding is required, control the lower second bidirectional motor 76 to work, drive the corresponding tooth fan 74 to rotate through the gear 75, and operate the iris mechanism 73 below, so as to open the channel between the temporary storage cylinder 72 and the blanking cylinder 71. At this time, the powder materials in the temporary storage cylinder 72 fall into the feeding tray 3, and the weight is detected by the pressure sensor 77. During this process, sealing is achieved through the dust-proof cover 41 and the sealing cover 42 to avoid dust generation. When the pressure sensor 77 detects that the weight is sufficient, reverse the second bidirectional motor 76 to close the blanking channel. Then control the first bidirectional motor 11 to work, so as to drive the feeding tray 3 to move towards the processing part 2 through the screw rod 9 until it completely passes over the processing part 2, and the powder materials enter the pressurizing holes of the processing part 2 to realize the feeding of the powder materials.

[0036] During this process, the sealing cloth 10 always abuts against the processing table 1 to prevent the powder materials from being extruded from the gap between the feeding tray 3 and the processing table 1. At the same time, the feeding tray 3 abuts against the push plate 43 to drive the sealing cover 42 to move synchronously. During this process, the sealing cover 42 and the dust-proof cover 41 always form a sealed space to avoid dust generation during feeding. Then control the first bidirectional motor 11 to reverse to return the feeding tray 3. During this process, when the feeding tray 3 passes by the processing part 2 again, secondary addition of the powder materials is carried out to avoid the situation where insufficient amount is added completely, resulting in quality problems. During the return process of the feeding tray 3, the excess powder materials are taken away by the sealing cloth 10. After the feeding tray 3 returns to the position directly below the blanking cylinder 71, control the upper second bidirectional motor 76 to work again, and the divided materials in the storage bin 5 enter the temporary storage bin through the discharge port 12. Repeat this operation to realize automatic blanking and control of the blanking amount, so as to realize fully automatic operation, and accelerate the production efficiency and production progress on the basis of ensuring the production quality.
