The locking and opening torque value of the bottle cap of the packaging bag in the box is one of the technical parameters for the off-line or on-line control of the production unit. Whether the torque value is suitable or not has a great influence on the central transportation and final cost of packaged goods. It is characterized by convenience, friendly human-computer interaction, double measurement form of locking force and opening force, active adherence to the peak value, multiple units of results showing and statistical analysis, high measurement accuracy and good stability, which is an indispensable experimental equipment in the production process.
The cursor usually chooses the dark color which has a big contrast with the background color, and it is better to use black. Usually, red and yellow cannot be used as the cursor color, nor can the color code with the same color as the photoelectric eye be used as the cursor color. If the light of the photo electric eye is green light, the light green color cannot be used as the cursor color of the electric eye, because the green light electric eye can not recognize the green color. If the background color is a deeper color (such as black, dark blue, deep purple, etc.), the time mark should be planned as a light colored cursor with hollow out and white.
The sealing function refers to the sealing reliability of the bag in the box. After the test, the integrity of the whole commodity packaging can be ensured, and the problems such as leakage, pollution and degeneration caused by the poor sealing function of the commodity can be prevented. There are many ways to test the sealing function, the most commonly used method is to use the sealing experiment instrument. The vacuum packaging is mainly to investigate the recovery status of the sample after the experiment. Of course, the above method is based on the principle of visual inspection, which is a qualitative test method. If you want to quantitatively check the sealing and leakage function of packaging, you can choose the sealing function test equipment of positive pressure principle, leakage and sealing strength tester.
