Problems solved by technology

[0002] At present, inspectors generally check the quality of metal packaging sheets by visual inspection. The manual inspection process is cumbersome and the accuracy is low, and it is still difficult to find the micropores in metal packaging such as cans. These extremely small pinholes can make food packaging Oxygen, water vapor, etc. gradually increase in the food, causing food to be contaminated by bacteria, causing food to deteriorate and taste, and then causing food poisoning to consumers, endangering human health, and causing economic or reputation losses to food manufacturers

Abstract

The invention relates to a photomultiplier pinhole detector, which mainly comprises a frame and a power source, wherein the frame is provided with a shading light anti-scuff bracket, the upper side of which is provided with a light box; the light box is internally provided with an ultraviolet tube; a detecting zone is arranged between the shading light anti-scuff bracket and the light box; the lower side of the shading light anti-scuff bracket is a main box body which is fixed on the frame; the main box body is internally provided with a camera bellows, the upper part of which is provided with a light inlet opening; an organic glass dust-free cover board is arranged on the light inlet opening; and the inner wall of the camera bellows is provided with a reflecting layer and the camera bellows is internally provided with a photomultiplier which is provided with a positive pole output. The photomultiplier pinhole detector obtained by the invention fast and intelligently detects pinholes on a production line by adopting a photoelectricity combination means, has very high detecting precision and detecting efficiency, and can effectively overcome subjectivity quality affirmation of detecting professionals which is carried out by experiments.

Description

technical field [0001] The invention relates to a detector, in particular to a photomultiplier tube pinhole detector used for detecting tiny microholes on metal packaging sheets. Background technique [0002] At present, inspectors generally check the quality of metal packaging sheets by visual inspection. The manual inspection process is cumbersome and the accuracy is low, and it is still difficult to find the micropores in metal packaging such as cans. These extremely small pinholes can make food packaging Oxygen, water vapor, etc. in the food gradually increase, causing food to be contaminated by bacteria, causing food to deteriorate and taste, and then causing food poisoning to consumers, endangering human health, and causing economic or reputation losses to food manufacturers. How to detect these cans with extremely tiny pinholes from the source, that is, the cutting stage of metal packaging materials, is a difficult problem that has not been solved in the field of meta...
