As shown in fig. 1, in one embodiment of a rewinding inspection machine according to the present utility model, an inspection module for inspecting quality of printed matter and a cutting and rewinding module for cutting and separating the printed matter and then rewinding the printed matter are disposed on a frame 1 of the rewinding inspection machine.

As shown in fig. 2, the inspection module includes a discharging roller 2, a first feeding roller 3, a deviation correcting mechanism 4 and an inspection mechanism 5 which are sequentially arranged. And is provided with a specimen control console 9 connected to the specimen module component.

The first feeding roller 3 is a driving roller and is used for conveying coiled materials from the discharging roller 2 to the deviation correcting mechanism 4.

The deviation correcting mechanism 4 is preferably a photoelectric deviation correcting (FIFE), and detects the position of the coiled material through a photoelectric sensor to control the transverse deviation of the coiled material, so that the coiled material is ensured to be in the detection position of the quality control mechanism 5. The deviation rectifying mechanism 4 is not limited to the FIFE, and other types of deviation rectifying mechanisms may be employed.

The inspection mechanism 5 is preferably an automatic photo-electric inspection mechanism including a detection lamp for lighting, a CCD high-speed camera for capturing images of printed matter, a processor for processing the images for quality detection, and an alarm device. The detection lamp is used for polishing the detection product, so that various use environments can be met. The CCD camera formed by the CCD device (charge coupled device, CCD) can change light into electric charge, store and transfer the electric charge, and can take out the stored electric charge to change the voltage, has the characteristics of small volume, light weight, no influence of magnetic field and shock and impact resistance, is more suitable for industrial scenes than the common CMOS camera, and is an ideal image generation camera for a safety and detection system. The processor compares the image data acquired by the high-speed camera with the printing standard image, and when detecting that the coiled material printing image has defects. The processor controls the alarm device to prompt the staff.

The inspection product control console 9 is used for controlling the start and stop and the operation mode of the inspection product module, and can control the continuous operation or the inching operation of the inspection product module, thereby facilitating the test and adjustment. The sample control console 9 is provided with an adjusting knob for setting the unreeling tension of the coiled material, and the unreeling tension is adjusted by controlling the rotating speed of the first feeding roller 3.

Firstly, placing coiled materials of a to-be-rewound inspected product on a discharging roller 2, and feeding the coiled materials into a deviation correcting mechanism 4 by bypassing a first feeding roller 3 to carry out position adjustment; the coiled material passes through the lower part of the inspection mechanism 5 for detection after the position deviation correction adjustment.

And is provided with a cutting and rewinding console 10 connected to each component of the cutting and rewinding module described above.

The second feed roller 6 is a drive roller having a speed matching the first feed roller 3 and feeds the web to the cutter roller 7.

The cutting roller 7 is provided with a plurality of cutting knives 71, which can cut and separate different printed matters on the same coiled material and can be used for cutting edges.

The rewinding rollers 8 are provided with a plurality of coiled materials which are cut into a plurality of strips through the cutting rollers 7, and each strip of printed matter is wound through the plurality of different rewinding rollers 8 respectively without mutual influence. One or more of the rewinding rollers 8 may act as reject rollers. When the inspector finds that the product is defective, the defective coil can be fixed to the reject coil and taken up by the reject coil. And the coiled material is re-connected to the rewinding roller 8 until the flaw parts are completely removed, so that the normal winding of other coiled materials is not affected.

The cutting and rewinding control console 10 is used for controlling the start and stop and the operation mode of the cutting and rewinding module, can control the continuous operation or the inching operation of the cutting and rewinding module, and is also provided with an adjusting knob which can independently control the operation speed of the cutting and rewinding module, thereby being convenient for independent test and adjustment.
