Problems solved by technology

[0003] At present, the quality inspection of pre-printed corrugated boxes is mainly completed by "carton pickers". If manual inspection is used for product inspection, more labor is required and the labor cost is higher. At the same time, the quality of manual inspection is easily affected by human factors (such as emotional fluctuations, etc.) ) impact, resulting in some unexpected quality problems

Embodiment 1

[0021] A high-precision flexographic intelligent detection method for wide-width color flexographic pre-printed corrugated boxes, comprising the following steps:

[0022] 1) Pre-printing of wide-format color flexographic web: select flexible resin plate, water-based ink and water-based varnish, and transfer the water-based ink and water-based varnish to the flexible resin plate evenly through a 200LPI ceramic anilox roller, and then pass The flexible resin plate transfers the graphics and texts to the substrate at a speed of 300m / min, and dries at a high temperature to make the ink layer dry and adhere firmly. Among them, the thickness of the flexible resin plate is 3.94mm, and the Shore hardness is 60; water-based The viscosity of the ink is 40 seconds, the coloring rate is 90%, the fineness is 35, and the pH value is 9.5; the water-based varnish is resistant to high temperature of 200°C;

[0023] 2) Corrugated cardboard line lamination process: the printed reel, pre-selected...

Embodiment 2

[0029] This embodiment is basically the same as Embodiment 1, the difference is:

[0030] 1) Pre-printing of wide-format color flexographic web: select flexible resin plate, water-based ink and water-based varnish, and transfer the water-based ink and water-based varnish to the flexible resin plate evenly through a 1500LPI ceramic anilox roller, and then pass The flexible resin plate transfers the graphics and texts to the substrate at a speed of 500m / min, and dries at a high temperature to make the ink layer dry and firmly attached. Among them, the thickness of the flexible resin plate is 1.14mm, and the Shore hardness is 80; water-based The viscosity of the ink is 30 seconds, the coloring rate is 100%, the fineness is 26, and the pH value is 7.5; the water-based varnish is resistant to high temperature of 16°C;

[0031] 2) Corrugated cardboard line lamination process: printed rolls, pre-selected corrugated base paper and container board paper, through the corrugated cardboar...

Embodiment 3

[0033] This embodiment is basically the same as Embodiment 1, the difference is:

[0034] Wide-format color flexographic web preprinting: select flexible resin plates, water-based inks and water-based varnishes, transfer the water-based inks and water-based varnishes to the flexible resin plates evenly through the 800LPI ceramic anilox roller, and then pass the flexible resin The plate transfers the graphics and text to the substrate at a speed of 400m / min, and dries the ink layer at a high temperature to make the ink layer dry and firmly attached. Among them, the thickness of the flexible resin plate is 2.42mm, and the Shore hardness is 70; the water-based ink The viscosity is 35 seconds, the coloring rate is 95%, the fineness is 30, and the pH value is 8.5; the water-based varnish can withstand high temperature of 180°C;

[0035] Corrugated cardboard line lamination process: the printed reel, pre-selected corrugated base paper and container board paper, through the corrugate...

Abstract

The invention discloses an intelligent high-precision flexographic printing detection method for a wide-width colored flexible preprinting corrugated carton. The method comprises the following steps: wide-width colored flexible web preprinting, corrugated board line overlapping, intelligent high-precision flexographic printing detection, paperboard throw-cutting and the scraps removing to finish detection of the wide-width colored flexible preprinting corrugated carton. Automatic adaption to printing production and quality detection is guaranteed, high-speed and high-precision quality detection is met by adopting a method based on a digital image processing technology, and online detection is realized under high-resolution and mass data conditions.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a high-precision flexographic intelligent detection method for wide-width color flexographic pre-printed corrugated boxes. Background technique [0002] In recent years, the level of pre-press and printing automation of packaging and printing enterprises has been continuously improved, and a large amount of labor has been liberated. However, they still rely heavily on labor in the quality inspection process. With the improvement of packaging quality and delivery cycle requirements in the terminal market, coupled with the accelerated increase in domestic labor costs year by year, the quality inspection system has begun to be favored by packaging and printing companies. Visual inspection technology is a new technology with the most development potential in the field of precision testing technology. It comprehensively uses electronics, photoelectric detection, image processing and c...
