What are the components of Touch and Close Fasteners Fatigue Tester

The Touch and Close Fasteners Fatigue Tester is used to test the hook and loop tape (velcro tape) repeatedly doing peeling and bonding actions. 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 Use a separately purchased 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 hook and loop fastener 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 hook and loop fastener tape on the wool 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 hook and loop fasteners fixed on the roller are continuously attached and peeled off. , In order to achieve the purpose of fatigue.

1. Roller diameter: upper wheel φ162.5mm, bottom wheel φ160mm;

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, it 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: the diameter is 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.
