Tinplate printing quality detection system

Abstract

The invention discloses a tinplate printing quality detection system which comprises a machine body shell, a working cavity is formed in the machine body shell, a water storage cavity with an upward opening is formed in the bottom wall of the working cavity, a filter screen is installed in the water storage cavity, a cleaning assembly capable of cleaning tinplate is arranged in the water storage cavity, and a hot water tank is arranged on the left side of the water storage cavity. A hot water cavity with an upward opening is formed in the hot water tank; a heating plate is mounted on the bottom wall of the hot water cavity; a dehumidifier can remove water vapor in the working cavity, so that the humidity in the working cavity is kept within a proper range; the detection module can shoot patterns on the tinplate, and then the color of the shot patterns is compared with a color library, so that whether the patterns printed on the steamed tinplate meet the standard or not is judged, and meanwhile, whether the tinplate has the phenomena of through printing, misting and black spots or not can be detected.

Description

technical field [0001] The invention relates to the technical field of tinplate quality detection, in particular to a tinplate printing quality detection system. Background technique [0002] Tinplate, also known as tin-plated iron, is a common name for electroplated tin-plated steel sheets. It refers to cold-rolled low-carbon thin steel sheets or steel strips coated with commercial pure tin on both sides. Use an iron printing machine to print text and icons on the surface of tinplate cans. After printing, you need to use testing equipment to detect the text and icons on the surface of tinplate cans, so as to avoid missing prints, flying ink and black spots. [0003] In the existing technology, the detection modules of the detection equipment are all installed inside the machine, which is difficult to clean, and it is easy to accumulate dust after a long time, making the lens of the visual detector blurred and affecting the detection results. The printed pattern is tested, ...

Problems solved by technology

[0003] In the existing technology, the detection modules of the detection equipment are all installed inside the machine, which is difficult to clean, and it is easy to accumulate dust after a long time, making the lens of the visual detector blurred and affecting the detection results. The printed pattern is tested, but the packaging cans made of tinplate must be sterilized by high-temperature cooking after packaging the food, so it is also necessary to test whether the printed pattern of tinplate will change color after high-temperature cooking
