Patent Name: Rapid Detection Method for Sealing Performance of Closed Flexible Packaging Bags Patent Applicant Nanjing Institute of Industry and Technology Principal Applicant Address 210016, inventor Li Haiping, No. 532-2, Zhongshan East Road, Nanjing, Jiangsu Province, China; Patent Application No. 200510041136.8 Application Date 2005.07. 22 Approval Date Approval Notice No. 1719218 Audit Notice Date 2006.01.11 Instruction CD-ROM D0602-1 Main Classification Code G01M3/26(2006.01) I Classification Number G01M3/26(2006.01)I;G01M3/36(2006.01)I Application No. Priority Abstract This invention discloses a rapid detection method for the sealing performance of a closed flexible packaging bag. Firstly, a closed flexible packaging bag sample and a closed flexible packaging bag to be tested are placed in a container and the container cover is closed; then the container is closed. Inflate the bag to the rated pressure and constant pressure for a period of time; Finally, quickly open the container sealing cover, observe the difference between the volume of the tested flexible packaging bag and the closed intact flexible packaging bag, and obtain the sealed performance of the tested flexible packaging bag. The invention can synchronously pressurize and depressurize externally the sealed intact flexible packaging bag samples and the multiple closed closed flexible packaging bags to obtain the sealed degree of each tested flexible packaging bag. Compared with the prior art, the operation method of the invention is simple, the detection speed is fast, and the detection result is accurate. It is especially suitable for quickly detecting the sealing performance of multiple flexible bags at the same time, which has great practical value. Sovereignty item 1, a rapid detection method for the sealing performance of a closed flexible bag, characterized in that it comprises the following steps: A) placing the closed intact flexible packaging bag sample together with the closed flexible packaging bag to be tested into a container and capping and sealing; ) Inflate into a closed container and pressurize it until the rated pressure of the package to be tested is constant and constant pressure; C) Open the container sealing lid quickly, observe the difference in volume of the tested flexible packaging bag and closed intact flexible packaging bag, and obtain the flexible package to be tested. Bag sealing performance.
Sliding Turnstile Gate features:
1. With fault self-checking and logic judgment functions, sliding barrier gate is convenient for users to maintain and function debugging.
2. Mechanical and infrared dual anti-pinch function, when the arm is blocked in the process of resetting, RFID sliding turnstile gate will automatically stop or rebound, and send out an alarm signal at the same time.
3. Multi-mode alarm function, including illegal intrusion, anti-intrusion, trailing, passing overtime alarm, etc.
4. Anti-shock function, when the AB sliding Boarding Gate opening signal is not received, the stop arm is automatically locked or alarmed.
5. Reverse intrusion closes the alarm function. When someone intrudes from the reverse direction after swiping the card in the forward direction, the flap will be quickly closed and an alarm will be issued.
6. Flexible traffic indication function, high-brightness indicator light and retractable barrier gate humanized prompt function, make the channel more distinctive.
