First, the product name: mattress roll durability tester
Second, model number: KHJ-023
Three main purposes: simulation of human sleep constantly rolling machines designed to meet the mattress manufacturers and various types of standards.
Fourth, functional requirements: equipment necessary to fully meet the criteria BSEN1957: 2000, ASTM F1566 test conditions related provisions, methods and functions. Meet the new Chinese national standard. Truly a machine!
V, the device works: This equipment is to achieve endurance strength test of the spring mattress rolling equipment, equipment is divided into three single, a rolling back and forth for the test bed, a measure for the deflection, the other plus side of a pressure test device. Load / deflection curve of a recording device vertical load 1000N (load-deflection curve in the 210N, 275N and 340N when the slope, so the computer automatically calculate the hardness value of Hy), and record the graph, the straight edge loading durable device 1000N ( 5000) and record the displacement of deformation after the completion of testing mattresses, mattress placed
Slab dropped out mattress.
Sixth, technical indicators
1, the center of the bed Durability:
1.1 Wheel: round wheel at the same time increase with the safety cover
1.2 oval wheel length: 1000 ± 2mm
Wheel diameter 1.3 Oval: 300 ± 1mm
1.4 oval wheel weight: 1400 ± 7N
1.5 scrolling speed: 16 r / min (stepless speed regulation)
1.6 Durability Test mattress used in Taiwan AIM rolling cylinder + Mitsubishi Electric servo motor system
1.7 The center bed is to use the scroll wheel testing machine fixed to the bed mattress moving rolling test. The freedom to do around the scroll wheel and left and right swing freely.
1.8 mattress through a dedicated fixture after installation of fixed and screw through the servo motor to move back and forth before and after the test, the test is completed automatically return to the origin location.
Hexagonal wheel
Length: 915 ± 75 mm
Roller diameter: 430 ± 25mm
Weight: 109 ± 4.5kg
Rolling speed: 20 rev / min
2, the load deflection
2.1 Deflection of the load cell capacity: 2000N
2.2 The load cell accuracy: ≤ ± 0.5%
2.3 Load Cell Resolution: 1 / 10000
2.4 Loading and unloading speed (90 ± 5) mm / min
Automatic measurement of the slope of 2.5 C1, the slope of C2, C3, and from 0 to 450N slope of the load deflection curve following regional standards for the area A and other parameters measured. Not be counted!
3, side pressure durability
3.1 Deflection of the load cell capacity: 2000N
3.2 Load Cell Accuracy: ≤ ± 0.5%
3.3 Load Cell Resolution: 1 / 10000
4, increase machine speed :0 - 200MM / Min can be set
5. Acquisition System: National Instruments 24-bit high-speed acquisition
6. Data storage: automatically save all the test data, any time convenient to call
7. Test Report: automatic generation of test reports, test data and may require the production curve
