The simulated hot sealing tester (cigarette box water mist tester) is a quality inspection equipment designed specifically for the tobacco packaging industry. Its core function is to simulate the high temperature and high pressure environment of the heat sealing film on the cigarette packaging line, and detect in advance whether there will be defects such as "water mist like whitening or fogging" on the surface of the cigarette label (cigarette box), thereby avoiding quality problems in mass production.
1、 Core advantages
(1)Full parameter fine control, covering a wide range of materials to support multi-dimensional flexible settings such as pressure of 3.5~9kg, temperature of 70~150 ℃, and testing time of 2~10s, easily meeting the experimental needs of the vast majority of thermoplastic materials.
(2)Ultimate consistency, eliminating manual errors using fully automatic loop control technology, completely eliminating data fluctuations caused by manual operations, ensuring that each set of test data has high repeatability and scientific research value.
（3）Intelligent interaction, touch future equipped with a 7-inch high-definition touch screen, with intuitive and concise operation logic. Support TCP/USB diversified communication, enabling seamless integration between data acquisition and transmission.
（4）Multiple safety escorts, people-oriented built-in automatic zeroing, anti leakage, overload protection, and one key emergency braking device. While pursuing extreme efficiency, we also safeguard the safety of operators and equipment in all aspects.
2、 Typical application scenarios
（1）Cigarette label printing factory: As a mandatory inspection item before leaving the factory, it verifies the stability of new batches of paper or new printing processes (such as UV varnish and laminating materials) to ensure that product quality meets requirements.
（2）Cigarette factory quality control: Conduct random inspections on the cigarette labels provided by suppliers to prevent packaging machine shutdown or substandard appearance of finished products due to water mist defects.
（3）Packaging material research and development: testing the temperature and moisture resistance of different film covering materials (such as BOPP film) or varnish formulations, providing data support for material selection or formulation improvement.
3、 Main functions and functions
（1）Simulated production line environment (accelerated testing)
Principle: Constant temperature heating and pressure are applied to the cigarette label cardboard through upper and lower heating plates, accurately reproducing the temperature (80-120 ℃) and pressure conditions of the heat sealing film in contact with the cigarette label during high-speed operation of the cigarette wrapping machine.
Value: Transfer potential problems on the production line (such as surface whitening caused by hot pressing) to the laboratory environment for rapid verification, shortening the problem discovery cycle.
（2）Qualitative/quantitative detection of "water mist" defects
Qualitative judgment: The operator visually observes the surface of the heated cigarette label (especially the film covered area or UV light oil area) to identify whether there are visual defects such as whitening, misty patches, or decreased glossiness.
Quantitative assistance (some high-end equipment): Integrated optical sensors (such as haze meters) can objectively quantify the degree of water mist by detecting changes in transmittance or haze values, reducing subjective errors in manual observation.
（3）Process optimization and quality interception
Application scenario: Mainly used for incoming material inspection in cigarette label printing factories and cigarette factories.
Function: Based on the test results, guide the printing process in reverse (such as adjusting the UV ink curing degree, optimizing the varnish formula), prevent large-scale waste caused by material moisture absorption and poor temperature resistance, and ensure that there are no water mist defects when packaging cigarette labels on the machine.
