[0019] An extension plate 20 extends from the lower edge of the front end of the tooth plate 17, and the extension plate 20 plays the role of being pushed by the L-shaped top frame 21. A ridge guide frame 15 is fixedly installed in the middle of the upper end of the extension plate 20, and a frame seat 19 is slidably installed on the outer surface of the ridge guide frame 15. The end of the frame seat 19 is fixed to the fixed seat 8. The ridge guide frame 15 and the frame seat 19 play the role of guiding the tooth plate 17.

An anti-sway frame 28 is fixedly installed at the front end of one of the claw seats 25, and the end of the anti-sway frame 28 fits into the upper end of the tooth plate 17. The anti-sway frame 28 can lock the tooth plate 17 so that the tooth plate 17 will not move up, thereby ensuring that the bottom pallet ear 30 can firmly support the stacked plastic pallets 38.
[0023] The opening member includes a secondary gas shell 26 that penetrates and is embedded in the middle of the claw seat 25. A secondary piston 37 is slidably installed inside the secondary gas shell 26. The secondary piston 37 is pushed by gas. The end of the secondary piston 37 penetrates from the lower end of the secondary gas shell 26. The end of the secondary piston 37 is embedded with a secondary pallet claw 24. The secondary piston 37 can drive the secondary pallet claw 24 to move downward to move the bottom plastic pallet 38 to separate it from the stacked plastic pallets 38.
[0024] The main gas shell 11 is inlaid in the middle of the fixed display frame 12, and the main piston 35 is slidably installed inside the main gas shell 11. The main piston 35 plays a role in pushing the gas in the main gas shell 11 into the auxiliary gas shell 26. The end of the main piston 35 passes through the lower end of the main gas shell 11, and the end of the main piston 35 is inlaid with a passive ear 13. The active ear 16 is fixedly installed on the upper front end of the tooth plate 17, and the end of the active ear 16 corresponds to the passive ear 13.

Then, the servo push cylinder 2 works to drive the concave frame 22 on the edge push frame 5 to move upward, so that the upward-moving concave frame 22 drives the push claw plate 32 to move to push the claw seat 25. At this time, the guide column 33 slides on the fixed display frame 12 to guide the claw seat 25, so that the two claw seats 25 move toward each other, so that the main tray on the claw seat 25 The claws 23 and the auxiliary tray claws 24 can be inserted between the edges of the two plastic trays 38 at the bottom from both sides to support the upper plastic tray 38. At this time, the L-shaped positioning claws 10 just fit on the concave frame 22 to keep the concave frame 22 still. At the same time, the L-shaped top frame 21 is in contact with the extended plate 20, and the anti-sway frame 28 on the claw seat 25 is separated from the upper end of the tooth plate 17 to release the locked tooth plate 17. Then the edge push frame 5 continues to move upward to drive the L-shaped top frame 21 to push the extended plate 20. At this time, the contraction spring 7 is deformed to adapt to the continued movement of the edge push frame 5. The tooth plate 17 is moved upwards by the extended plate 20, so as to drive the gear 29 to rotate, thereby driving the bottom tray ear 30 on the ear shaft 31 to flip, so that the bottom tray ear 30 is separated from the bottom plastic tray 38. At this time, the active ear 16 and the passive ear 13 on the tooth plate 17 are in contact, and then the edge push frame 5 continues to move upwards to drive the tooth plate 17 to move upwards, so that the active ear 16 on the tooth plate 17 can push the passive ear 13, so that the main piston 35 can slide in the main gas shell 11, so that the gas in the main gas shell 11 passes through the connecting pipe 3 4. The hose 27 is pushed into the auxiliary gas shell 26, so that the auxiliary piston 37 in the auxiliary gas shell 26 can move downward under the push of the gas, thereby driving the auxiliary pallet claw 24 to move downward to move the bottom plastic pallet 38, so that the bottom plastic pallet 38 can be separated from the stacked plastic pallets 38, and fall on the conveyor 1 under its own weight to be transported away, and then the main pallet claw 23 and the bottom pallet ear 30 are reset, so that the upper plastic pallet 38 can fall on the bottom pallet ear 30, and this cycle is repeated to separate the stacked multiple plastic pallets 38 and complete the tray separation operation.
