Abstract

The invention relates to the technical field of self-adhesive label paper detection devices, in particular to a visual detection device for self-adhesive label paper production, which comprises a workbench, a winding part and an unwinding part, and is characterized in that the workbench is provided with a first visual detection module and a second visual detection module; a plurality of guide rollers used for adjusting the direction of label paper are arranged on the workbench, a positioning locking piece is arranged in the middle of the workbench, a continuous detection unit is arranged on the portion, close to the first visual detection module, of the workbench, and a vacancy patching unit is arranged on the portion, close to the second visual detection module, of the workbench. According to the visual detection device for self-adhesive label paper production, aiming at the vacancy problem existing on a label paper roll, the device is provided with the positioning locking piece, the continuous detection unit and the vacancy supplementing and pasting unit which are matched for use, the label paper is allowed to be rapidly supplemented and pasted in the detection process, shutdown operation is not needed, the pain point of'shutdown supplementing 'of traditional equipment is solved, and the production efficiency is improved. And the detection efficiency is obviously improved.
