As shown in the figure, initially, the two front arms are respectively located outside the two hot presses and in a state that the trimming plate is lifted, at this time, the extrusion in the hot press 801 is released, the ecological plate 901 is located in each layer of the hot press to wait for being pulled out, and then the following steps are performed:

1. the motor 501 drives the mounting rack and the fixed mounting plate 363 connected with the mounting rack to synchronously move forwards through the combined action of the driven gear 506, the horizontal transmission shaft 502, the vertical transmission shaft 503 and the bevel gear pair, when the fixed mounting plate 363 moves, the two front extending arms can be synchronously driven to move forwards, the front ends of the front extending arms and the pulling plate are promoted to enter the hot press from two sides of the ecological plate, and at the moment, the pulling plate and the front extending arms are linearly arranged.

7. When the side edge of the trimming plate 107 contacts with the remaining edge and moves down by 1-3cm, the moving frame 120 moves up through the moving cylinder, and the two ends 107-1 of the trimming plate 107 with the V-shaped structure are bent towards the middle part oppositely to form an inverted V-shaped structure, namely bent towards the inner side, so that the damage to the end part of the ecological plate caused by the contact of the end part of the side edge of the trimming plate 107 with the end part of the ecological plate can be avoided, and the moving cylinder stops after the trimming plate 107 moves up and resets.

8. The motor continues to act and drive the forward arm to continue to drive the ecological plate to move forward until the forward arm pulls the ecological plate back to the supporting frame, when the end of the ecological plate is pulled out of the hot press, the end of the ecological plate first contacts with the roller 302 at the end of the supporting frame 301 and is guided onto the supporting frame 301 through the roller 508, and then the motor stops.

9. When the rear edge of the ecological plate enters the supporting frame 301, the pulling plate is reset by the pulling-back cylinder 361 by the pulling-back mechanism, and the pulling plate moves in the reverse direction and linearly releases the contact with the ecological plate with the front extending arm, so that the ecological plate can be pulled out from the hot press.

10. The pushing cylinders 124 in the shifting mechanism reversely move and are connected with four corners of the portal frame 101 through telescopic shafts of the pushing cylinders 124 and drive the portal frame 101, the moving frame 120 and the trimming plate 107 to move towards the tail end of the ecological plate and move the trimming plate to the upper part of the front end of the ecological plate, and then the pushing cylinders 124 stop moving;

11. and repeating the steps 6 and 7 to finish the edge cutting treatment of the remaining edge of the tail end of the ecological plate.

The ecological plates of all layers in the hot press can be pulled out through the actions, and the trimming of the remaining edges of the front end part and the rear end part of the ecological plates is completed, so that the production efficiency is greatly improved, and the labor intensity is reduced.
