Butt jointing and correcting device for paper conveying

The utility model discloses a butt jointing and correcting device for paper conveying. The device comprises a correcting mechanism, an offset detection mechanism, a butt jointing mechanism and a controller. The correcting mechanism comprises a correcting rotating frame arranged on a rack, a horizontal push-pull air cylinder for driving the correcting rotating frame to horizontally rotate relative to the rack is arranged on the part, below the correcting rotating frame, of the rack, and a front correcting roller and a rear correcting roller are fixed to the front end and the rear end, in the paper moving direction, of the correcting rotating frame. The butt jointing mechanism comprises a platform arranged on the upper surface of the correcting rotating frame and used for spreading paper in the butt jointing process of paper, a front beam and a rear beam, wherein the front beam and the rear beam can used for fixing the paper in the butt jointing process relative to the platform in a lifting mode. Due to the fact that the paper correcting mechanism and the paper butt jointing mechanism are combined, the butt jointing and correcting device for paper conveying achieves correcting of the paper and also butt jointing of the paper, the structure is reasonable, the length of a production line is not increased, and it can be ensured that the paper is effectively corrected in time in the butt jointing process.
