The use of roller box method to detect down the anti-drilling properties of down products, suitable for testing all kinds of down products, is a professional test equipment.

 Brief Introduction:

The use of roller box method to detect down the anti-drilling properties of down products, suitable for testing all kinds of down products, is a professional test equipment.
Structural features:
1, the instrument by a positive, reverse rotation of the rotating box, electrical control part of the composition;
2, the rotary box for the plexiglass material inside the smooth square cube;
3, the instrument has a smart preset number of revolutions, full number of self-stop and other functions.
Standards compliant:
GB / T 12705
The main parameters:
1. Rotary box body size: 450 × 450 × 450mm
2. Rotary box speed: 45r / min, positive and negative
3. Rotation setting: 1 ~ 9999 times, LED display
4. Rubber ball: 10 / box; Hardness: 45 ± 10; Weight: 140 ± 5g; Material: Butyl rubber
5. Power: AC 220V ± 10%, 50Hz, 200W
6. Dimensions: 850 × 650 × 800mm
7. Weight: 60kg
 Main features:
1. Computer processor control, equipment operation to terminate the automatic shutdown alarm;
2. Counter: LED liquid crystal display can be set, and with a calibration system to ensure the stability of equipment operation;
3. Transparent polyacrylonitrile safety cover, easy to implement the observation of the operator;
4. The whole machine is 316 stainless steel, strong and generous.
Test principle:
1, the first sample made of bags, built a certain quality of the down, put the test instrument of the rotating box, while in the rotating box is also loaded with hard rubber ball;
2, the rotating box to a certain speed of rotation, the rubber ball from a certain height fall, the impact of the sample, to simulate the down products in the course of taking a variety of extrusion, rubbing, collision and so on;
3, by counting the number of drill holes drilled from the inside of the sample to assess the fabric's anti-drilling performance.
