DRK3011B Comprehensive testing machine for rolling thickness measurement of children’s mattress

Instrument use：

It is used for the durability test of children’s mattress surface rolling and the test of the height of the cushion surface.

Standard：

Customer settings

Features：

1. Imported force sensor, accurate measurement.

2. The instrument adopts high-quality AC servo motor and force sensor.

3. Color touch screen display and control, Chinese and English interface, menu operation mode.

4. The core control components use STMicroelectronics’ 32-bit single-chip microcomputer to form a multi-function motherboard.

5. Shutdown mode: the machine will shut down when the number of tests is reached, if the test piece is damaged or the deformation is too large, it will automatically shut down and give an alarm.

6. The equipment has a fault self-diagnosis system.

7. Mattress height test coordinates can be set arbitrarily, and the number of points can be set arbitrarily.

Technical parameter：

1. Children’s mattress test roller: round roller with hard, smooth surface and no scratches, and a safety cover; oval roller length: 600±2mm; oval roller diameter: 160±1mm; oval roller weight: 400 ±2N;

2. Loading frequency: (10～20) rev/min;

3. The friction coefficient is between 0.2～0.5;

4. The rotational moment of inertia of the drum should be 0.5±0.05kg ㎡;

5. Test times: 0～99,999 times can be set arbitrarily;

6. The accuracy of the force measurement device is not less than 1%, the accuracy of the size device is not less than 1mm, and the position deviation of the loading block is ±5mm;

7. Height measurement: 1) Precision: ±0.5mm; 2) Height measurement pad: measurement surface It is a flat and smooth rigid cylinder;

8. Measuring pad diameter: 100mm, chamfer R10; 4) Pad applying speed: 100±10mm/min;

9. Vertical downward force: Apply 4N force, at this time, the distance between the bottom surface of the circular cushion and the flat plate is the height of the cushion surface of the mattress;

10. Measuring height: the initial cushion surface height of the mattress, after 100 times, after 9900 durability tests, measure the cushion surface height respectively;

11. Mattress height test points: ≤50 points;

12. Power supply: AC220V, 50Hz;

13. Dimensions: 2800mm×2800mm×2200mm (L×W×H);

14. Weight: about 320Kg;
