Mattress Roller Height, Firmness and Edge Durability Combined Testing Machine

TST-C1031  Mattress combined tesing machine for roller durability,height ,firmness and edge pressure durability-mattress tester
 

1-Usage

The machine is suitable to evaluation the soft/hardness of mattress and surfacing durability test.

2-Principle

This instrument use cylindrical or hexagonal load roller to apply repeated load on parts of the test of the horizontal mattress ,to test the bearing capacity of  mattress on the long-term repeated loading;and adopt 355mm diameter disc to pressure three point on the mattress to determine the hardness of mattress(total 10 levels, 1-5 level is  hardness, 6-10 is software)

3-According Standard

 BS EN 1957 and ASTM F1566-99 Part 7.

4-Main parameter

1-Roller: hexagonal load roller apply 1400±7N on the mattress,

2-Height measuring load pad: level and smooth and rigid cylinder,high strength POM plastic material 

3-Software/hardness load pad surface is smooth,diameter 355mm of rigid cylinder is made of high strength POM plastic 

4-The running speed of 90±1 mm/min when height and hardmess measuring device in loading and unloading

5-Height and hardness measuring device can automatic measure the total load,height effort is ±0.5mm,load effort is ±1N

Control device technical specification

1- elegant appearance, all hidden wiring, greatly improving the security against the risk of leakage and any power system.

2-  gantry mechanical structure, the use of high-precision servo motor,increase the use life and accuracy of test data.

3-  Low-noise high-precision ball screw and linear guide as transmission parts, improving the overall mechanical strength and stiffness, effectively reduce operating noise,roller load the used of sliding bearings to free load, loading force closer to the standard requirements

4-   Edge load module  through the servo motor to drive load pad free movement up and down,using the load block+linear sliding bearing free load,inear bearings rolling friction (friction coefficient: 0.002), ensure the accuracy of loading force to meet with standard requirements.

5-    Height,length and width is adjustable to fit different sie of mattress specimen

6-    Adopt TST intelligent software,operation control is easy,test program will be auto-completed,and display the specimen harndess value(H),hardness level(HS),and record the operation state.
