[0025] Working principle: A label printer is a device used to print various types of labels, such as address labels, express labels, and barcode labels, and label printers are usually suitable for retail, logistics, and medical industries. In order to ensure the quality of label printing, it is necessary to use visual inspection equipment to inspect the printed labels. When the existing visual inspection structure inspects the label, the distance between the inspection device and the label is fixed. As the label is rolled up, the distance between the inspection device and the label changes, making it impossible for the inspection device to focus accurately, resulting in inaccurate inspection results. In order to solve this problem, a detection mechanism and an adjustment mechanism are set up, and one end of the label is passed through the bottom end of the rubber roller 11 and the auxiliary rollers 17 on both sides, and one end of the label is wrapped and fixed on the collection roller 21. The servo motor 19 is controlled to drive the hollow shaft 20 at the output end. The rotation of the rotating disk 10 drives the collecting roller 21 to rotate, so that the collecting roller 21 collects the labels into a roll, and at the same time drives the labels to move inside the rubber roller 11 and the auxiliary roller 17. At this time, the driving motor 18 can be controlled to drive the output end screw 14 to rotate, thereby pushing the slider 15 to slide up and down inside the slide groove 13, so that with the cooperation of the fixed plate 16, the auxiliary roller 17 is driven to rise and fall to a suitable height, thereby flattening the labels for easy inspection or collection. In the collection process, the turntable 10 can be rotated to drive the threaded rod 9 to rotate, so that with the cooperation of the threaded groove 8, the lifting platform 7 is driven to extend and retract to a suitable length inside the sleeve 5, thereby changing the distance between the detection device body 6 and the label, making the detection result of the detection device body 6 more accurate, and solving the problem of inaccurate detection results caused by blurred imaging of the existing detection structure.
