Simmons mattress rolling device at constant linear speed

The invention provides a Simmons mattress rolling device at a constant linear speed. The Simmons mattress rolling device comprises a winding disc, a lower driving roller, an upper driving roller, an upper driven roller, a lower driven roller, a Simmons mattress, a first roller, a spindle, a second roller, a second lever, a first lever, a tension spring, a rotating shaft and a range sensor, whereinthe Simmons mattress is preliminarily compressed by the upper driven roller and the lower driven roller, and the Simmons mattress is compressed for the second time by the upper driving roller and thelower driving roller. The Simmons mattress rolling device at the constant linear speed is further provided with a winding disc radius detection mechanism, so that the real-time radius of the windingdisc is obtained, and the rotating speed of the winding disc is adjusted by a controller according to the real-time radius of the winding disc, so that the Simmons mattress is wound at the constant linear speed by the winding d
