Author:QINSUN Released in:2023-03 Click:84

Main purpose:

Shanghai Qianshi Shoelace and Shoe Eye Abrasion Tester Price is suitable for the friction test between shoelaces and shoelaces, used for testing the abrasion resistance of shoelaces woven with different materials such as cotton, hemp and chemical fibers.

Applicable standards:

EN ISO 22774, DIN-4843, QB/T-2226, SATRA, TM 93/154, BS 5131, GB/T 3903.36-2008

Test Principle:

Shanghai Qianshi Shoelace And Shoe Eye Wear Resistant Testing Machine PriceTake two shoelaces, hook the middle part to form the right one, for the left side use the right clamp ( moving clamp) of the machine to clamp the two ends of the right belt. After clamping, the two ends are naturally separated by 25mm. Using a sample gauge, the right strap is connected to the left strap at 52.2°, and the distance between the hook point and the grab point is 120mm. Use follow ups the left clamp (fixed clamp) to clamp one end of the left belt, place the other end in the pulley groove and hang the weight underneath. The natural distance between the clamping point and the wheel groove is 35 + 5 mm. During the test, the movable clamp moves in a straight line at a constant speed. , so that the middle parts of the two shoelaces rub against each other, and record the number of rubs when the test reaches the specified number of rubs or when the shoelaces break.

Technical parameters:

1. Distance between moving clamp and fixed clamp: 310mm (max)

2. Moving clamp stroke: 35 mm

3. Moving clip speed: 60 ± 6 cycles/min

4. Test clip: 4 sets

5. Test Sample Gauge: Angle Angle52.2°, Distance Space120mm

6. Test code: 250±3g, 4 pieces

7. Counter: LCD liquid crystal display, 0~999, 999

8. Test Power: DC Servo Servo 180W

9. Instrument power supply: 1∮, AC110V, 10A/220V, 5A

Sampling Requirements:

1. Take 4 or the above (2 sets or more) shoelace sample test.

2. The shoelace samples parked in the lab environment for more than 16 hours.

Test steps:

1. Take 4 or more shoelace samples to test;

2. The shoelace samples are parked in the lab environment for 16 hours. ;

3. Hook the middle of the two shoelace monsters;

4. Clamp the right shoelace monster:

Loosen the movable clamp Place the two ends of a shoelace in the two grooves of the lower splint of the movable holder, and turn the butterfly knob slightly to tighten;< /p>

The sample meter is placed in the test On the stage, the lower end of the sample the meter sits against the lower end of the movable holder and the upper end is placed in the right shoelace so that the right shoelace left shoelace hooks under oneangle of 52.5°;

Unscrew the clampFix the screw on the shoelace, place the bottom clip on the sample gauge and align it, then insert the two sides of the right shoelace into the groove of the bottom clip, put the top clip on the shoelace and align it with the sample gauge, fix it with The screws are firmly locked.

Tighten both ends of the right shoelace and secure the butterfly knot.

5. Clamp the left shoelace sample:

Place one end of the left shoelace in the roll and tie it to the hook of the 250g weight;

Place the other end of the left shoelace into the groove of the fastener, pull the shoelace so that the tied weight is at the bottom of the roller and lock the butterfly knob.

6. Take away the sample meter;

7. Start the power switch, set the number of tests;

8. Start the test button, start the test;

9. After the number of tests is reached, remove the sample, observe the degree of friction of the sample, and judge according to the standard requirements. If the number of tests is not reached, it is broken and the number of times it breaks must be recorded.
