Abstract

This invention discloses a fluid discharge system and the squeezer thereof. The squeezer includes a pair of rolling shafts, a driving device, and a mounting bracket, wherein the pair of rolling shafts is rotatably mounted on the mounting bracket. Each rolling shaft has a mounting part at each of both ends and a squeezing segment located between the mounting parts. A pair of rolling shafts can operatively clamp an object to be clamped between the squeezing segments and can rotate oppositely through a driving device to apply a squeezing force to the object clamped. The squeezing segment includes a supporting shaft and an elastic body provided around the supporting shaft. The squeezer also has a protective device for protecting the elastic body at the end of the squeezing segment. The discharge system provided by this invention is a zero-residue discharge system needing not to hanging the liner bag, and has a simple structure, a good manufacturing process, simple operation, and cost savings.
