[0035] As Figures 5 to 9 shown, the flipping mechanism 3 includes a number of support rods 34 and turntables 32 connected to both ends of the number of support rods 34. The two turntables 32 are limited by the support rods 34. The outer circle of the turntable 32 is covered with a felt, and the felt is connected to the turntable 32 through a dust-proof pressing plate, so that the turntable 32 forms a seal with the installation housing 2. A number of conveying roller assemblies 35 and a blocking assembly are provided between the two turntables 32.

[0037] The conveying roller assembly includes a main driving roller 351 and a number of driven driving rollers 352 arranged side by side with the main driving roller 351. Both ends of the main driving roller 351 and the driven driving rollers 352 respectively protrude from the two turntables 32. One end of the main driving roller 352 is connected to a first helical gear 362. A conveying motor 36 is installed on the turntable 32 above the first helical gear 362.

[0038] A detection in-place block 311 is sleeved on one end of the main shaft 31 connected to the rotary cylinder 111. The rotary cylinder 111 is installed on the support frame 1 through a rotary cylinder bracket 11. A bearing bracket 12 is fixed on each of the support frames 1 on both sides of the installation housing 2. The rotary cylinder bracket 11 is arranged outside the bearing bracket 12. A detection in-place photoelectric switch 114 is provided on the bearing bracket 12.
[0039] Oppositely arranged clamping jaws 38 are installed on the inner side walls of the two turntables 32 through clamping jaw shafts 381. Photoelectric brackets 322 are installed on the outer side walls of the two turntables 32. A transmissive photoelectric switch 321 and a blowing interface are provided on the photoelectric brackets 322. The arrival of the crucible is detected by the transmissive photoelectric switch 321, and the blowing interface blows air into the interior of the installation housing 2 to prevent material accumulation from blocking the transmissive photoelectric switch 321 and affecting the detection effect.
[0040] Specific working principle: The sagger is transported to one side of the support frame 1 by the external transmission mechanism. The gate cylinder 62 on this side drives the gate plate 63 to rise, and the sagger is conveyed from the inlet of the installation housing 2 to the conveying roller assembly and stops blocked by the blocking plate 374. The automatic sealing gate on the rear opening is closed. After the sagger is detected in place by the opposed photoelectric switch 321, the gate cylinder 62 drives the gate plate 63 to descend. The turning mechanism 3 is driven to turn by the rotary cylinder 111, the gripper 38 blocks the sagger, and the powder in the sagger is poured downward. After the in-place detection photoelectric switch 114 detects that the sagger has been turned in place, it turns back to the initial position in the reverse direction. During the feeding process, the return filter 41 of the dust collection assembly 4 works, filters the dust in the installation housing 2 and returns it to the housing 2, and then enters the feed hopper 51 of the feeding assembly 5; after the pouring is completed, the cylinder 37 pushes out the piston rod, and the installation end of the cylinder 37 moves in the reverse direction, pushing the arc-shaped connecting rod 372 to rotate, and further causing the blocking mounting shaft 373 to rotate, driving the blocking plate 374 to rotate, so that the blocking plate 374 is all located below the conveying roller assembly 35. The conveying motor 36 is started to drive the second helical gear 361 to rotate. The second helical gear 361 drives the first helical gear 362 to rotate, and the main driving roller 351 rotates. The driving gear 353 on the main driving roller 351 drives the driving gears 353 on the adjacent driven driving rollers 352 to rotate in sequence through the driven gears 354, engaging the remaining driving gears 353 and the remaining driven gears 354 in sequence, realizing the rotation of the driven driving rollers 352. The gate cylinder 62 on the other side drives the gate plate 63 to rise, and the sagger is conveyed out from the sagger outlet of the installation housing 2. The cylinder 37 is reset, and the gate cylinder 62 drives the gate plate 63 to descend.
