What are the components of the button belt fatigue testing machine?

The button belt fatigue testing machine is used to test the button belt (velcro tape) repeatedly doing peeling and fitting actions, so that after a certain number of times, the test piece is rolled with the weight of the roller itself to make it fit evenly, and then another Purchase a tensile testing machine to measure its adhesion and adhesion strength.

Applicable standards:

DIN-3415, GB/T 3903.20, GB/T 3903.21, GB/T 23315, ISO 22777, ISO 22776, SATRA PM123

 

Test principle:

Fix the hook surface and rough surface (also called loop surface) of the button belt on two rollers with diameters of 162.5 mm and 160 mm, respectively. The hook surfaces of the two rollers are in contact with the button tape on the rough surface, and a certain load is added according to its width. The lower roller is the power wheel, which drives the load roller to rotate repeatedly, so that the button tape fixed on the roller is continuously attached and peeled off. To achieve the purpose of fatigue.

2. Roller width: 70mm;

3. Rolling speed: 60rpm/min;

4. Reversal time: 30S reversal;

5. Test load: 5kg;

6. Fixture slot: width 4mm, length 55±2mm;

7. Horsepower: AC1/8HP dual frequency motor;

8. Counter: LCD display, 0-999,999.

 

Technical features:

1. The number of automatic shutdowns can be set;

2. High-precision, durable stepping motor;

3. The weights can be changed quickly;

4. Stainless steel roller;

5. The number directly displays the value, with high accuracy, rapid display, good stability and convenient reading.

 

Instrument composition:

The whole machine is mainly composed of the following parts:

1. Counterweight: used with the driven wheel, the pressure is 5kg.

2. Driving wheel: The diameter is 160mm, which is driven by the motor to rotate, the speed is 60rpm, and it reverses every 30s. The ring surface is fixed on the driving wheel.

3. Driven wheel: diameter of 162.5mm, driven by the drive wheel to rotate. The hook surface is fixed on the driven wheel.

4. Counter: set and display the number of laps.

5. Buttons: including emergency stop buttons, start and pause buttons.
