[0022] In this embodiment, the heating, forming and unloading processes can be carried out simultaneously through the cooperation of the hot pressing forming mechanism 3 and the unloading mechanism 5. The three-station design significantly improves production efficiency and helps to improve the quality of plastic box products.

The feeding mechanism 5 includes a third cylinder 51 fixedly connected to the top outer wall of the support frame 4 by screws, a connecting plate 52 fixedly connected to the piston rod of the third cylinder 51, connecting rods 53 evenly distributed on the bottom outer wall of the connecting plate 52, and a feeding head 54 fixedly connected to the bottom outer wall of the connecting rods 53.

[0024] In this embodiment, the feeding mechanism 5 can automatically transport the finished products to the designated position, stack the finished products in an orderly manner, avoid damage to the finished products, simplify the collection process, and the control system of the PLC controller 9 can automatically coordinate the work of each station, reduce manual intervention, and reduce the difficulty of operation.
