[0039] The conveyor belt 14 is provided with a power motor I 32 for providing power therefor, and the conveyor belt 2 is provided with a power device 32 for providing power therefor.

[0040] Working process:

[0041] The finished preforms 1 that have been boxed and shrunk are continuously conveyed to the conveyor belt 2 through the conveyor belt 14. When the boxed preforms 1 are conveyed to the palletizing station Ⅰ20 for palletizing, the cylinder Ⅱ24 is first started to drive the movable guide plate 23 to rotate until the movable guide plate 23 is connected to the fixed guide plate Ⅱ22. The boxed preforms 1 are introduced into the switch platform 5 of the palletizing station Ⅰ20 under the action of the conveyor belt 2, the fixed guide plate Ⅰ19 and the movable guide plate 23. At this time, the two blanking plates 15 of the switch platform 5 of the palletizing station Ⅰ20 are in a horizontal state (closed state), and the induction sensor The sensor 18 transmits the signal to the cylinder Ⅰ16, and the cylinder Ⅰ16 moves downward, thereby driving the unloading plate 15 to rotate downward to open the unloading plate 15, and the boxed preforms 1 fall into the tray 28 above the stacking airbag 6. The air in the stacking airbag 6 flows to the air storage airbag 7 through the exhaust pipe 8 under the control of the regulating valve 11 and the solenoid valve 12. By controlling the air flow rate, the total height of the stacking airbag 6 is reduced by the height of the boxed preforms 1, and the tray 28 holding the boxed preforms 1 is lowered by the height of the boxed preforms 1. Then the switch platform 5 is closed with the upward movement of the cylinder Ⅰ16. By analogy, this stacking station Ⅰ20 can stack 7 layers of boxed preforms 1. At this time, the air in the stacking airbag 6 flows into the air storage airbag 7, and the air storage airbag 7 is filled.

[0042] When the boxed preforms 1 are transferred to the palletizing station II 21 for palletizing, the cylinder II 24 is first started to drive the movable guide plate 23 to rotate to the fixed guide plate II 22 on one side of the conveyor belt 2, so that the boxed preforms 1 can directly reach the palletizing station II 21 along the conveyor belt 2 and be palletized in the same process as the palletizing station I 20. When the palletizing of the palletizing stations I 20 and II 21 is completed, the collection of 14 boxed preforms 1 is completed.

[0043] The boxed preforms 1 are pushed from the palletizing mechanism to the unloading area, and the boxed preforms are taken out one by one from the top of the palletizing shell. As the boxed preforms 1 above the palletizing airbags 6 decrease one by one, the air in the air storage airbags 7 flows back to the palletizing airbags 6 from the return pipe 9 through the one-way valve 13 under the action of the counterweight box 10. Every time a boxed preform 1 is taken out, the refluxed gas raises the palletizing airbags 6 by the height of a boxed preform 1, and the tray 28 above the palletizing airbags 6 rises accordingly, so that the boxed preforms to be taken are always at the top of the palletizing shell until all the stacked boxed preforms 1 are taken out. The air is reused in the whole process.
