Overview
The MIT paper Folding tester is a new type of instrument developed according to the national standard GB/T 2679.5-1995. It has the functions of parameter testing, conversion, adjustment, display, memory, printing and data processing, and can directly obtain the statistical results of various data. The instrument has a compact structure, small size, light weight, full function, horizontal table placement, convenient operation and stable performance. It is suitable for the determination of various Cardboard folding resistance.
Features
1. In line with the national standard GB/T 2679.5 - 1 9 9 5; 2. With parameter testing, conversion, adjustment, display, memory, printing functions; 3. With data processing function, can directly obtain statistical results; 4. Compact structure, small size, light weight; 5. Lying table placement, easy to operate; 6. Stable performance; 7. Optical mechatronics structure; 8. Smooth and reliable transmission; 9. Automatic counting and stop function; 10. Automatic homing function; 11. Can count the experimental data of multiple samples in the same group and print.
Principle
The MIT paper Folding tester is an opto-mechatronics structure. The mechanical part drives the crank and slider mechanism to realize the translation of the rack through the motor, and then drives the folding chuck to rotate back and forth 135 ° through the rack and pinion drive, which is stable and reliable. The tension mechanism deforms the tension spring by pressing the tension rod, forming a spring force to exert force on the tested pattern. The electrical part detects the count of the number of double folds through the photoelectric circuit, and automatically stops the motor after the test is completed. At the same time, the folding chuck is automatically returned, and parameter setting, measurement display, action control and data statistical printing can also be carried out.
Applications
Determination of folding resistance of various Cardboard
Standards
GB/T2679.5-1995
Steps
1. Set parameters; 2. Place the test sample; 3. Start the instrument for testing; 4. The instrument automatically counts and stops; 5. View and print statistical data.
Notice
• Power supply voltage is AC220V, 50HZ; • Select the appropriate spring tension according to the test pattern; • Check the distance setting of the folding opening; • Maintain the mechanical transmission part regularly; • Avoid use in humid or vibrating environments.
