[0028] Specifically, the operator stacks the carton boards on the extension component 3 and transports them to the carton board warehouse 4, and then transports the carton boards to the carton board feeder 5. The carton board feeder 5 transports the carton boards one by one to the carton board opening component, and the two opening turntable mechanisms 66 cooperate with each other to realize pre-opening of the carton boards. After the pre-opening, the carton boards are transported to the forming packaging box conveyor line for rapid forming. The entire carton board conveying and pre-opening operation is convenient and fast, and by adopting a continuous paper picking method, the paper picking speed is fast, the paper picking action is stable, and there is no paper missing phenomenon.

[0029] Furthermore, the extension component 3 includes a carton board feeding and conveying component 32 arranged on the conveying platform 2. The conveying platform 2 is connected to a side baffle at the edge along the length direction through a side baffle adjustment mechanism 31, and a tail baffle 33 is fixedly connected to the carton board feeding and conveying component 32 on the conveying platform 2. When personnel need to place carton boards, the carton boards are stacked on the carton board feeding and conveying component 32, and the carton boards are pushed so that the carton boards are aligned with the side baffles. The tail baffle 33 is used to support the tail of the carton boards, so as to realize the automatic replenishment of the carton boards to the carton board bin 4 conveniently and quickly.

[0030] Further, the carton board bin 4 includes a carton board feeding component 44 connected to the active end of the carton board feeding and conveying component 32. A baffle board 43 is provided at the tail end of the advancing direction of the carton board feeding component 44.

First, the paper picking suction cups 662 on the first carton opening turntable 661 sequentially suck and rotate the carton boards to the second carton opening turntable 663. The rotation valve 65 is used to control the vacuum pumping and blowing actions of the paper picking suction cups 662 on the first carton opening turntable 661 and the second carton opening turntable 663. When the carton board sucked by the paper picking suction cup 662 on the first carton opening turntable 661 rotates to the position where it is connected to the paper picking suction cup 662 on the second carton opening turntable 663, the suction cups on the second carton opening turntable 663 sequentially suck the carton board. During the rotation, the suction cup on the first carton opening turntable 661 blows air to release the carton board, completing the action of opening the carton board. The suction cups on the second carton opening turntable 663 suck the pre-opened carton board and continue to rotate until the lower edge of the carton board contacts the pushing block of the conveying line and is formed along the conveying direction. The suction cups on the second carton opening turntable 663 blow air to release the carton board, and at this time, the entire process of paper picking and pre-opening and forming of the carton is completed.
