The embodiment comprises a front frame 1 and a rear frame 2 connected to each other, the front frame 1 is connected to a conveying platform 3, a movable front suction cup group 4 and a rear suction cup group 5 are installed on the rear frame 2, two groups of front and rear photoelectric sensors 6 are arranged at the front end of the conveying platform 3, a group of left and right photoelectric sensors 7 is arranged at one side of the front end of the conveying platform 3, the front suction cup group 4 is connected to a left and right positioning telescopic motor 8, the two ends of the rear suction cup group 5 are respectively connected to the front and rear positioning telescopic motor 9, the front and rear photoelectric sensors 6 are correspondingly connected to the front and rear positioning telescopic motor 9, and the left and right photoelectric sensors 7 are connected to the left and right positioning telescopic motor 8. The front suction cup group 4 and the rear suction cup group 5 are respectively installed on the front and rear tracks 10 of the rear frame 2, and the upper front suction cup group frame 11 and the lower front suction cup group frame 12 are connected in sequence between the front suction cup group 4 and the front and rear tracks 10. The lower front suction cup group frame 12 can move along the front and rear tracks 10. The upper front suction cup group frame 11 is placed on the left and right tracks 13 at the top of the lower front suction cup group frame 12. One end of the left and right positioning telescopic motor 8 is connected to the upper front suction cup group frame 11, and the other end of the left and right positioning telescopic motor 8 is fixed to the lower front suction cup group frame 12. An upper rear suction cup assembly frame 14 and a lower rear suction cup assembly frame 15 are sequentially connected between the rear suction cup assembly 5 and the front-to-back track 10. The lower rear suction cup assembly frame 15 can move along the front-to-back track 10. The front-to-back positioning telescopic motor 9 is installed on the lower rear suction cup assembly frame 15, one of the front-to-back positioning telescopic motors 9 is hinged on the lower rear suction cup assembly frame 15, and the other front-to-back positioning telescopic motor 9 is fixed on the lower rear suction cup assembly frame 15. A slide rail 16 is fixed on the top of the front-to-back positioning telescopic motor 9, and a support block 17 is connected to the front end of the front-to-back positioning telescopic motor 9. The support block 17 is connected to a slider 18, and the slider 18 can move along the slide rail 16. The bottom of the upper rear suction cup assembly 14 is connected to a rotating shaft 18 on both sides, and the rotating shaft 18 is inserted into the bearing of the support block 17.

[0022] By adopting the paperboard positioning and adjusting device for paper feeding in carton processing of the present invention, the paperboard to be fed in is placed on the plane formed by the conveying platform 3, the front suction cup group 4 and the rear suction cup group 5, the negative pressure pipeline connected to the rear suction cup group 5 is connected to give suction force to the suction cup of the rear suction cup group 5, firmly sucking the paperboard, and at the same time starting the rear power telescopic motor connected to the lower rear suction cup group frame 15, so that the rear suction cup group 5 drives the paperboard forward. In the forward process, when the front end of the paperboard is about to reach the position of the front and rear photoelectric sensors 6, the two front and rear photoelectric sensors 6 respectively give corresponding front and rear positioning telescopic motors 9 pulse signals, and the front and rear positioning telescopic motor 9 at one end that reaches the position of the front and rear photoelectric sensors 6 does not move. At this moment, the front and rear positioning telescopic motor 9 at one end that has not reached the position of the front and rear photoelectric sensors 6 quickly extends forward, pushing the upper rear suction cup group frame 14 to move forward to this end The paperboard reaches the position of the front and rear photoelectric sensors 6 and stops, so that the front and rear ends of the paperboard are positioned, that is, the inclined paperboard is completely horizontal. Since the cardboard has a very small tilt angle, and the forward speed of the entire rear suction cup assembly 5 is much smaller than the twisting speed of the upper rear suction cup assembly frame 14, at the moment of twisting, the forward distance of the other end is negligible. Since one of the front-to-back positioning telescopic motors 9 is hinged to the lower rear suction cup assembly frame 15, and the other is fixed to the lower rear suction cup assembly frame 15, and the lower end of the upper rear suction cup assembly frame 14 is connected to the support block 17 through the rotating shaft 19, the upper rear suction cup assembly frame 14 can rotate relative to the two front-to-back positioning telescopic motors 9. The front-to-back positioning telescopic motor 9 pushes the slider 18 to move, and the slider 18 moves on the slide rail 16, and can also serve as a support for the upper rear suction cup assembly frame 14. After the front and rear positioning is completed, the suction force of the rear suction cup group 5 is cut off, and the suction force is applied to the suction cup of the front suction cup group 4 at the same time. The front power telescopic motor connected to the lower front suction cup group frame 12 drives the cardboard forward, and a pulse signal is given to the left and right photoelectric sensor 7. The left and right positioning telescopic motor 8 drives the upper front suction cup group frame 11 to move along the left and right track 13. When the end of the cardboard reaches the position of the left and right photoelectric sensor 7, it stops, and the left and right positioning of the cardboard is completed. In this way, the comprehensive positioning of the cardboard is completed and it can be sent to the next process. The front and rear track 10 is relatively long, and the front and rear position of the rear suction cup group 5 can be adjusted. The left and right photoelectric sensors 7 are installed at both ends of the groove of the bracket. The bracket can move left and right on the front frame 1 to adapt to cardboards of different sizes.
