7. The shaping device based on the polylactic acid composite material according to claim 6, characterized in that: The gear disc assembly includes a driving gear (22) and a rotating rod (23). At the middle of the bottom of the driven I-shaped wheel (17), a rotating rod (23) is installed. On the outer side of the rotating rod (23), a driving gear (22) is installed. The driving gear (22) meshes with the rack (9). The bottom of the rotating rod (23) is fixed to the gantry fixed frame (12) through a bearing. The second lifting assembly includes a limiting sliding groove (28), a side sliding rod (27), a lifting slider (26), a second vertical lifting motor (32), a side sliding strip (30) and a second vertical lifting screw (31). The limiting sliding groove (28) is installed on both sides of the U-shaped base (2). And inside one group of limiting sliding grooves (28), there is a side sliding rod (27). Inside the other group of limiting sliding grooves (28), there is a second vertical lifting screw (31). At the bottom of one group of limiting sliding grooves (28), a second vertical lifting motor (32) is installed. The output end of the second vertical lifting motor (32) penetrates through the limiting sliding groove (28) and is fixed to the second vertical lifting screw (31). The outer side of the second vertical lifting screw (31) is sleeved and meshed with the side sliding strip (30). The outer side of the other group of side sliding rods (27) is sleeved with a lifting slider (26).

8. The processing method of the shaping device based on the polylactic acid composite material according to claim 7, characterized in that: The steps are as follows: Step 1: Connect the feeding pipe (11) with the pipeline for transporting the polylactic acid composite material. Start the feeding pump to make the polylactic acid composite material enter the feeding pipe (11) through the pipeline and be introduced into the lower mold groove (14) through the feeding pipe (11). Step 2: Start the first vertical lifting motor (19) to adjust the movement of the first vertical lifting screw rod. Drive the lifting cylinder (7) through the first vertical lifting screw rod to make the upper mold (8) fall and insert into the lower mold groove (14) to form a combined structure of a plastic nozzle and a notch for molding the polylactic acid composite material. Step 3: Synchronously adjust the movement of the driving I-shaped wheel (20) when the first vertical lifting screw rod is moving. Adjust the movement of the transmission belt (18) through the driving I-shaped wheel (20), and adjust the driven I-shaped wheel (17) through the transmission belt (18) to drive the rotating rod (23) to move. Step 4: Synchronously drive the movement of the driving gear (22) through the movement of the rotating rod (23). Adjust the rack (9) to move away from the lifting cylinder (7) through the driving gear (22), and further adjust the feeding pipe (11) to retract away from the lower mold groove (14). Step 5: After the molding is completed, start the lower mold flipping motor (5) to adjust the rotation of the lower mold groove (14) to face the suction cup cover (15). Step 6: Start the second vertical lifting motor (32) to adjust the movement of the second vertical lifting screw rod (31). Adjust the side sliding bar (30) to rise through the second vertical lifting screw rod (31) until it fits the bottom of the plastic nozzle with the suction cup cover (15). Step 7: Start the air pump to make the lower mold groove (14) adsorb the plastic nozzle, and then reverse-start the second vertical lifting motor (32) to adjust the reverse rotation of the second vertical lifting screw rod (31) to remove the plastic nozzle through the suction cup cover (15). Step 8: Start the suction cup flipping motor (25) to adjust the flipping rod (29) to drive the suction cup cover (15) to flip and face the conveyor belt (3), and transport the plastic nozzle through the conveyor belt (3).
