[0003] However, coated paper faces many quality problems in the production process. Among them, pinhole and uneven coating defects are particularly prominent. The existence of pinhole defects greatly reduces the leakproof performance of coated paper, and when packaging liquid or moisture-sensitive goods, leakage is likely to occur, which not only affects the quality and shelf life of the product, but also causes economic losses. Uneven coating will lead to inconsistent protective performance of coated paper, and some areas will not achieve the expected moisture-proof and oil-proof effect, which will also affect its performance in actual application.

[0004] The conventional detection method mainly relies on manual visual inspection or water immersion test, which has the problems of low efficiency, poor precision, easy secondary pollution, etc. There are some detection devices based on optical or electrical principles on the market, but these devices generally have the shortcomings of complex structure, high cost, difficult maintenance, etc., which are difficult to meet the actual needs of small and medium-sized enterprises.

[0010] Further, the negative pressure pump is fixedly connected to the inner bottom wall of the frame body, and the end of the connecting pipe away from the air outlet valve is fixedly connected to the air suction end of the negative pressure pump.

[0011] Further, the left side of the detection cylinder is fixedly connected with an air inlet valve, the air inlet end of the air inlet valve is fixedly connected with a gas conveying hose, and the other end of the gas conveying hose is fixedly connected with an air cylinder.
