After binding, it needs to be cooled to solidify the glue so that the publication pages are firmly bound. After that, they are cut to have neat corners. Generally, due to the large number of printed materials, the binding effect of the binding line is only inspected by random sampling. During the inspection, the inspector needs to hold the printed materials and check the binding conditions of the binding line one by one, which makes the inspection efficiency slow.

[0030] Preferably, a first limiting rod is fixedly connected to the top of the detection plate 46 , and the first limiting rod movably passes through the bottom of the movable plate 44 .

[0031] Preferably, the conveying component 2 includes a motor 21, a conveying roller 22, and a conveyor belt 23. The motor 21 is fixedly mounted on the back of the machine body 1, the conveying roller 22 is fixedly connected to the output end of the motor 21, the conveyor belt 23 is sleeved on the conveying roller 22, and the placement frame 3 is fixedly connected to the conveyor belt 23.

[0035] Working principle: Place the publication in the placement frame 3 so that the binding of the publication is at the top, fix the publication by the second spring and the clamp, rotate the screw sleeve 42, the screw sleeve 42 drives the moving plate 44 to rise and fall through the connecting rod 43, so that the probe 47 is at the same height as the top of the publication, and start the motor 21 to drive the conveyor belt 23 to convey the publication. When the placement frame 3 moves, the rack 49 on the placement frame 3 will mesh with the rotating gear 411, thereby driving the rotating gear 411 to rotate, and the rotation of the rotating gear 411 will drive the rotating drum 410 to rotate, thereby driving the sliding rod 412 to rotate, and the rotation of the sliding rod 412 will drive the rotating rod 413 to rotate through the gear set, thereby driving the cleaning brush 414 to clean the top of the publication. At the same time, when the publication moves, the probe 47 will move on the top of the publication, so as to detect the flatness of the top of the publication. When the probe 47 detects the publication, it drives the detection plate 46 to move up and down under the action of the first spring 45. When the publication is When the flatness exceeds the index, the displacement of the detection plate 46 will exceed the specified value, and the signal will be transmitted to the inkjet printer 48 through the capacitive displacement sensor. The inkjet printer 48 is started to mark the publications that do not meet the standards. When the publication is transmitted to the bottom of the elastic sheet 417, the push block 416 is driven down by starting the first electric push rod 415, thereby driving the elastic sheet 417 to drop.

When the adhesion strength of the publication is low, cracks will occur. By starting the second electric push rod 51, the mounting plate 52 is driven to move, so that the friction block 55 contacts the side of the publication, and the pressure value between the friction block 55 and the publication is sensed by the pressure sensor 53. When the publication continues to move, the publication is subjected to a force opposite to the transmission direction of the publication when passing through the friction block 55, thereby further detecting the adhesion strength of the publication. When the adhesion strength of the publication is low, cracks will occur.
