[0032] In summary and in combination with the above drawings, the working principle of the automatic feeding and discharging centrifugal dryer 100 of the present invention is described in detail as follows:

[0033] During operation, the workpiece is transported to the hopper 531 through the conveyor belt. When the hopper 531 is not fully loaded, the lifting mechanism 52 drives the hopper mechanism 53 to rise to the upper end of the drum 12. At the same time, the lifting mechanism 141 drives the cover 13 to rise away from the drum 12, and then the rotating mechanism 142 drives the cover 13 to move away from the drum 12. After that. The second linear drive 33 drives the swing rod 32 to swing, so that the drum 12 approaches and tilts toward the side of the hopper mechanism 53. At this time, the material channel drive 535 drives the material channel 534 to extend and reach the opening of the drum 12; then, the door drive 533 drives the door body 532 to open, so that the workpiece slides from the hopper 531 into the drum 12. Then, the second linear drive 33 drives the swing rod 32 to swing to reset the drum 12, and the drive motor drives the drum 12 to rotate. The heating device 15 blows hot air into the drum 12 for drying. During this process, the first telescopic cylinder 421 extends to drive the first lifting plate 422 to rise, so that the clamping assembly 44 rises to the second tray below; then the clamping cylinder 441 drives the clamping block 442 to extend and clamp the second tray below, and then the second telescopic cylinder 431 extends to drive the second lifting plate 432 to rise, so that the second tray and the trays above it rise. At this time, the push cylinder 451 starts to drive the push rod 452 to move horizontally, and the push rod 452 pushes the first tray below onto the first conveying roller group 46. The first conveying roller group 46 transports the tray to the bottom of the drum 12 and makes the tray above the lifting mechanism 62. In addition, when the tray is transported out, the tray above is the first tray below after the first lifting assembly 42 and the second lifting assembly 43 are lowered. Therefore, according to the above operation, the trays can be repeatedly transported out one by one. When the roller 12 has finished drying the workpiece, the cover opening mechanism 14 opens the cover 13, the first linear drive 31 drives the swing rod 32 to swing, and the second linear drive 33 drives the connecting rod 34 to swing, so that the roller 12 can rotate greatly, thereby reaching a flipping state, and finally the workpiece in the roller 12 falls onto the material tray. When unloading is completed, the output end of the third telescopic cylinder 621 contracts, so that the output end slides from the proximal end of the chute to the distal end. At this time, the lifting drive member 622 is forced to move upward and lift the material tray, so that the material tray leaves the first conveying roller group 46. In addition, the transmission mechanism 625 starts to drive the transmission chain 624 to run, and the transmission chain 624 drives the material tray to move to the second conveying roller group 61, and the second conveying roller group then conveys the material tray out to achieve unloading.

[0034] Compared with the prior art, the present invention provides a tray conveying device 4 on the first side of the centrifugal dryer 1, a pouring device 5 on the second side of the centrifugal dryer 1, and a discharging conveying device 66 on the third side of the centrifugal dryer 1. The tray conveying device 4 can convey an empty tray to the bottom of the centrifugal dryer 1, and the pouring device 5 can automatically convey the workpiece to the top of the centrifugal dryer 1 and pour the workpiece into the centrifugal dryer 1, and then the centrifugal dryer 1 is turned over by the turning drive mechanism 3, and the dried workpiece can be poured onto the tray, and finally the workpiece is sent out by the discharging conveying device 66. Therefore, the whole process is automatic loading, automatic drying, automatic discharging and automatic unloading, realizing fully automated production, avoiding manual operation, reducing labor intensity, improving production safety, and greatly improving production efficiency, which is conducive to mass production.
