DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] As shown in Figures 1-6 A self-adhesive label overprint automatic deviation correcting device includes: a U-shaped conveying frame 1 with an open top end, a supporting frame 2 is fixedly connected to the top end surface of the two longitudinal members of the conveying frame 1, and an identification module 201 with a CCD lens structure is further fixedly connected to the bottom end surface of the transverse member of the supporting frame 2.

[0027] Two support mechanisms 3 are fixedly connected to the front and rear sides of the conveyor frame 1. Correction push rods 301 are fixedly connected to the inner side of the two support mechanisms 3. A connecting plate 3011 is fixedly connected to the inner output end of the two correction push rods 301. Two connecting frames 3012 are fixedly connected in a straight array on the side of the connecting plate 3011 away from the correction push rods 301. Correction rollers 3013 are rotatably connected to the inner side of the connecting frame 3012. A screening push rod 2012 is fixedly connected inside the conveyor frame 1. A push plate assembly 2013 is fixedly connected to the front end face of the screening push rod 2012. The push plate assembly 2013 is flush with the waste rack 2011. The screening push rod 2012 and the push plate assembly 2013 together form a pushing and feeding structure for paper bags that are placed too crookedly.

[0028] The connecting frame 3012 and the straightening roller 3013 together form the straightening structure for the paper bag. Two support legs 101 are fixedly connected in a straight line array on the bottom surface of the conveyor frame 1.

[0029] The inner side of the conveyor frame 1 is rotatably connected to a conveyor roller 1012. There are two conveyor rollers 1012 in total. The two conveyor rollers 1012 are rotatably connected to the inner side of the conveyor frame 1 in a linear array. A conveyor belt 1013 is installed on the outer side of the two conveyor rollers 1012. A servo motor 1011 is installed on the left side of the front end face of the conveyor frame 1.

[0030] The rear output shaft of the servo motor 1011 is connected to the conveying roller 1012 located on the left side. The servo motor 1011 and the conveying roller 1012 together form a conveying structure for paper bags. The front end of the conveying frame 1 is provided with a notch, and a waste rack 2011 is fixedly connected inside the notch. The waste rack 2011 is inclined.

[0031] When the equipment is started, the servo motor 1011 installed on the left side of the front end of the conveyor frame 1 starts to work. Its rear output shaft drives the conveyor roller 1012 located on the left side to rotate. Since the conveyor belt 1013 is installed on the outside of the two conveyor rollers 1012, and the conveyor rollers 1012 are connected to the inside of the conveyor frame 1 in a linear array, as the left conveyor roller 1012 rotates, the conveyor belt 1013 starts to run, thereby driving the right conveyor roller 1012 to rotate synchronously, thus realizing the conveying of paper bags placed on the conveyor belt 1013. This constitutes the conveying structure for paper bags.

[0032] The recognition module 201 of the CCD lens structure fixedly connected to the bottom end surface of the transverse member of the support frame 2 starts to play a role in the conveying process, and the recognition module 201 monitors the position of the paper bag in real time, and can accurately judge whether the paper bag is inclined or deviated in position by using optical imaging and image recognition technology;

[0033] When the recognition module 201 detects that the paper bag deviates in position, a signal is sent, at this time, the deviation correction push rod 301 installed in the inside of the support mechanism 3 opposite to the front and rear sides of the conveying frame 1 is started after receiving the signal, the inside output end of the deviation correction push rod 301 pushes the connecting plate 3011, the connecting plate 3011 drives the two connecting frames 3012 fixedly connected in a straight line array on the side away from the deviation correction push rod 301 to move, since the deviation correction roller 3013 is rotatably connected to the inside of the connecting frame 3012, the movement of the connecting frame 3012 makes the deviation correction roller 3013 contact the paper bag and apply an external force to the paper bag, so as to adjust the paper bag to the correct position, and the deviation correction structure composed of the connecting frame 3012 and the deviation correction roller 3013 completes the deviation correction operation on the paper bag;

[0034] If the paper bag is placed too obliquely, even after correction, it cannot meet the overprint requirements, at this time, the screening push rod 2012 fixedly connected in the conveying frame 1 is started, the push plate assembly 2013 fixedly connected to the front end surface of the screening push rod 2012 is pushed to the waste frame 2011 by the screening push rod 2012, the waste frame 2011 is fixedly connected in the notch opened in the front end of the conveying frame 1 and is arranged obliquely, so as to facilitate the paper bag to slide and collect, and the push down structure composed of the screening push rod 2012 and the push plate assembly 2013 completes the processing of the unqualified paper bag.
