Description

Technical Field

[0001] The utility model relates to the technical field of deviation correction and guidance, in particular to a deviation correction and guidance machine suitable for a printing press. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places where the text and image are on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. Printing presses are prone to deviation during paper feeding. After searching, a Chinese patent with publication number CN216583196U discloses a correction and guiding device for book and periodical printing, which includes a machine base, a conveyor belt and a driving mechanism for moving the conveyor belt are arranged on the machine base, a guide mechanism is arranged on one side of the conveyor belt, and the guide mechanism includes a support plate, a sliding frame and a clamping assembly. The two sides of the support plate are respectively connected to the side walls of the machine base, the sliding frame is arranged on the support plate, and the clamping assembly The first driving member is connected to the side wall of the sliding frame, and a driving assembly for driving the sliding frame to move is also provided on the support plate. When in use, when the paper is transmitted, the operator starts the driving motor, the rotating roller and the pressure roller rotate, and the paper is transmitted from the conveyor belt to between the rotating roller and the pressure roller, and finally transmitted to the printing area. When the paper deviates during the transmission process, the operator starts the first driving member, and the first driving member drives the sliding block to move, and the sliding frame moves. At this time, the wedge block slides in the wedge groove, and the pulley rolls along the length direction of the moving groove. After the position of the paper is corrected, the first driving member is closed, and the sliding frame stops moving, thereby adjusting the position of the paper. However, this correction method has a large friction force on the paper, which is easy to cause wear to the middle printing part of the paper. Utility Model Content

[0025] Specifically, it also includes two movable plates 9 arranged on the front and rear sides of the frame 1, the guide wheel 7 and the correcting wheel 8 on the same side are rotatably connected to the movable plate 9 through the mounting frame 10, the mounting frame 10 is rotatably connected to the movable plate 9, the guide wheel 7 and the correcting wheel 8 are respectively rotatably connected to the mounting frames 10 on their respective sides, the correcting motor 11 is fixedly installed on the top of the movable plate 9 and can drive the mounting frame 10 connected to the correcting wheel 8 to rotate, the rotation angle sensor 12 is fixedly installed on the movable plate 9 and the mounting frame 10 connected to the guide wheel 7 is fixedly connected to the movable plate 9, the correcting wheel 8 and the two guide wheels 7 as well as the correcting motor 11 and the rotation angle sensor 12 can be supported by the movable plate 9 and the three mounting frames 10, and the guide wheel 7 or the correcting wheel 8 can be supported by the mounting frame 10.

[0026] Specifically, it also includes a position adjustment mechanism for driving the movable plate 9 to slide up and down and forward and backward. The position adjustment mechanism includes a lifting drive cylinder 14 fixedly mounted on the frame 1. The top output shaft of the lifting drive cylinder 14 is fixedly mounted with a lifting frame 15 that cooperates with the up and down guide sliding of the frame 1. The movable plate 9 cooperates with the lifting frame 15 to slide horizontally forward and backward. The lifting frame 15 is fixedly mounted with a horizontal driving cylinder 16 that drives the movable plate 9 to slide forward and backward on the lifting frame 15. Through the position adjustment mechanism, it is convenient to adjust the movable plate 9, the correcting wheel 8 and the two guide wheels 7 up and down and forward and backward as a whole.

[0027] Specifically, it also includes a conveying drive mechanism, which includes a conveying motor 13 that drives a drive roller 2 at the end to rotate. The conveying motor 13 is fixedly installed on the frame 1. Through the conveying drive mechanism, the center conveyor belt 3 and the four side conveyor belts 4 can be driven to rotate, so that the paper can be transported. The conveying motor 13 is started to drive a drive roller 2 at the end to rotate.
