At present, with the development of computer science, machine vision technology plays an increasingly important role in the printing and packaging industry as a new quality control method. The off-line printing defect detection system adopts machine vision as a core technology, carries out defect detection on the printed packaging product on a single product inspection machine, can effectively detect the packaging product with printing defects, and has important significance for guiding the first few production processes of the printed product.

In the production process of general medicine packages, daily chemicals and social packaging products, printing processes such as gloss oil, film covering and the like are used for improving the image-text effect on the surface of a printed matter, so that the surface of the printed matter is more attractive, and the printed image-text fading and paper moisture can be prevented, but the printing processes are often characterized in that: 1. the product has more static electricity on the surface and is easy to adsorb dust and paper hair; 2. the surface of the paper of the product is easy to scratch and is not wear-resistant. Powder lubrication can be used when the sheet-fed printing press runs, so that dust on the surface of a printed matter generally comes from an offset printing workshop; in addition, the large-sheet product can be subjected to a die cutting process after being printed, a large amount of paper fluff can be produced after the product is subjected to die cutting, one part of the paper fluff can be adhered to the edge of the small-sheet product, and the other part of the product floats in the air and is adsorbed to the surface of the printed product by the product with static electricity.

Therefore, before printed product paper enters a quality inspection process, dust and paper dust are inevitably generated, and when the printed product paper with the paper dust and the paper dust passes through a high-speed product inspection machine, the product inspection machine is inevitably subjected to false detection, unnecessary waste removal is caused, and the detection efficiency is influenced. The paper writing paper powder can float to the surfaces of the light source and the lens, so that the service life of optical components is influenced; how to effectively remove dust and collect paper powder and paper wool becomes a technical problem which must be overcome at present in the printing and detecting industry. The problem is solved, and the product competitiveness of the product inspection machine can be greatly improved.

The existing methods for solving the problem generally adopt the following two methods: 1. dedusting by adopting a brush; 2. dedusting by adopting an electrostatic ion wind device; however, the brush can scratch the product, and the brush needs to be cleaned and replaced regularly, is easy to fall, and has poor usability, so the brush has poor dust removal effect and cannot adapt to products with films and water-based gloss oil; moreover, the static ion wind power is too small, and the blown dust can fall everywhere and be stained on the light source and the lens, so that the detection effect and the service life of the lens are influenced; and the paper feeding device is not provided with a dust collecting device, and cannot be suitable for the type of reverse side paper feeding detection.
