TN4278 Mattress Durability Comprehensive Tester
This tester is designed according to the latest national standard.It is suitable for a set of durability testing for spring soft
mattress,and relevant measurement of it.It uses a certain weight of roller to do rolling test on the center of mattress,
simulating the effects to the mattress when people sleep and roll on it.
The tester does loading durability test to the edge of mattress using specified loading cushion and force value.It can also
simulate a people sits on the edge of the mattress,and the effect caused by the bottom loading on the mattress.
After a certain number loading,compare the height of cushion surface,surrounding edge and hardness changes,as well as
damage to before and after the test.Assess the quality of the mattress quality.
Test items: include the following tests and measurement projects:
1.Durability test for the cushion surface.
2.Durability test for the edge of cushion.
3.Height measurement of the mattress.
4.Measurement of the Hardness value.
1.The design is novel, highly integrated, advanced control.
2.The tester can complete the test and measurement alone instead of needing three machines before.It makes its
operation more reliable and test data more accurate by using advanced control system and optimized structure.
3.The frame of the tester is made of high strength industrial aluminum.It is generous and beautiful and has science and
technology sense because Sheet metal parts of it is made by advanced electrostatic spray painting process.
4.Built-in sample,Provide more safety testing process, prevent the machine from injuring .
5.Switches are distributed in many places which can make sure that we can turn off them in case of any emergency.
Durability test for the cushion surface:
1.Adopt independent control system.PLC control separately.Cooperate with Color touch screen.It is convenient and visual to
operate.The testing process and the running status is clear to us, test times can be set freely.
2.Special lift device is convenient to lift up the heavy roller and easy to move it to the test area of the mattress.Then put down
the roller and make its own weight fully load to the surface of the mattress.
3.Roller can move up and down in the testing process, to adapt to concave and convex surface of the mattress.
4.When doing durability test of edge, roller can be moved to the parking area behind the instrument.
5.Durability test for cushion surface is driven by servo motor,it is quiet,steady and reliable to operate.
6.Adopt advanced photoelectric sense technology. The beginning position of the center line of the cushion surface return to
the home position automatically.Both stroke end auto-induction,parking area position sense.
Durability test for the edge of cushion/ Measuring equipment:
1.Adopt independent control system, using dedicated high-precision and high intelligent ARAM controller
and special test software.It can run under WINDOWS system on PC, full operated by software, The interface of software
is easy to operate.
2.Special test software on PC, WINDOWS operating page, a high degree of compatibility.
3.Test program has already been set on the software on PC according to the test requirement.One key to test. It is
convenient for operator to learn and save the training time.
4.The curve window of test software display the values of force and shift in real time,multi-coordinate model.
5.Measured results can be output into editable test report, high compatibility and editable with WORD format.
6.High precision force sensor, loading force value accurately.
7.Servo motor and ball screw pair drive, stable and reliable operation, high control precision, and loading speed can be set.
8.Using high resolution encoder sensing displacement, displacement precision is high.
9.Edge loading cushion and measuring loading cushion are used interconvertible generic connection head.Sharing a set of
driving device, save space and cost.
10.Adjustable rack.The pressure plate can be adjusted the position along the direction of X and Y.It can measure each point
of the mattress.It is different from the tradition way to separate .The test can be finished without moving the sample.
11.Save a lot of testing time, greatly reduces the working intensity, operators can achieve single operation, save the company
12.Force sensor avoid overloading damage to the core components.
1.Rolling test stroke:The mattress mid-line left and right are both 500 mm.
2.Rolling test speed:16±2 cycle per minute
3.Roller:1400N,The middle diameter:300mm,Both ends diameter:250mm,length:1000mm
4.Counter:0- 999999 can be set.
5.The control way of rolling:Touch screen + PLC control
6.Loading cushion on the edge:buttocks shape,380mm*495mm
7.Loading parts on the edge:The midpoint on the long edge of the mattress.200 mm from edge.
8.Loading force on the edge:1000 N
9.Loading time on the edge:3 s
10.Position of measurement:Mattress center,Left and right are both 250mm,the midpoint on the long edge of the mattress
200 mm inward.
11.Loading plate of measurement:Diameter 355mm,Radius of curvature of the end R800mm
12.Capacity of force sensor:2kN
13.Loading speed of measurement:90±5mm/min
15.Drive motor:Servo motor
