LT-JJ29-B Computerized National Standard Mattress Rolling, edge Pressing and Height Measurement Testing Machine (Rolling + edge pressing + height measurement)

Short Description:

This Computerized National Standard Mattress Rolling, Edge Pressing, and Height Measurement Testing Machine performs three critical assessments on mattresses. It simulates long-term rolling during sleep with a rolling load module, applies compressive forces to test edge durability, and automatically measures mattress height. Designed to evaluate product lifespan and quality for innerspring, foam, and fiber mattresses, it operates in full compliance with national mechanical testing standards.

Product parameters
1	Control mode:	Computer control
2	Pavement durability test device	(1) Mechanical device capable of driving the roller to move relatively horizontally on the surface of the mattress: the rotational moment of inertia of the roller is (0.5±0.05) kg /m ², the loading frequency should be (16±2) times /min, the static load is (1400±7) N, and the test times are greater than 30,000 times. (2) Roller: Elliptical, with an external dimension tolerance of ±2mm. The surface should be hard, smooth, free of scratches and other surface defects. The length is (1000±2)mm, and the friction coefficient is between (0.2 and 0.5). Roller chamfer: R30. The maximum diameter of the roller: 300±1mm. (3) Motor: Panasonic servo motor from Japan; 4) Test stroke: 250mm on each side of the centerline of the mattress; (5) The accuracy of the force measurement device shall not be less than 1%, the accuracy of the dimensional device shall not be less than 1mm, and the position deviation of the loading block shall be ±5mm.
3	Edge durability test device	(1) Loading pad size: 38049575mm. Its surface is hard and smooth. It is connected to the test equipment and can rotate around the horizontal axis on the vertical plane (2) Vertical downward loading force: 1000N (3) Total number of tests: 5,000 times (4) Load holding time: (3±1) seconds
4	Height measurement device	(1)Height measurement accuracy: ±0.5mm; (2) Height measurement pad: The measurement surface is a flat and smooth rigid cylinder. (3) Measuring pad diameter: 100mm, chamfer R10; (4) Force application speed of the spacer block: 100±20mm/min; (5) Vertical downward force: Apply a force of 4N. At this time, the distance between the lower surface of the circular pad and the flat plate is the height of the mattress surface. Measure the height: After conducting 100 durability tests and 29,900 durability tests on the initial mattress surface, measure the height of the mattress surface respectively. Height measurement system: By setting the force value through software and applying force vertically downward at a fixed speed, it is directly connected to the PLC touch screen.
