FLUID DISCHARGE SYSTEM AND SQUEEZING PUSHER THEREOF

摘要

A fluid discharge system and a squeezing pusher thereof. The squeezing pusher (1) comprises a pair of rolling shafts (10), a drive apparatus (20), and a mounting bracket (30), the pair of rolling shafts (10) being rotatably mounted on the mounting bracket (30), each rolling shaft (10) having a mounting part (11) positioned at both ends and a squeezing section (12) positioned between the mounting parts (11), the pair of rolling shafts (10) being capable of operably clamping a clamped object between the squeezing sections (12) and rotating in opposite directions by means of the drive apparatus (20) in order to apply a squeezing pushing force to the clamped object; the squeezing pusher (1) further comprises a pressure detection apparatus (200) and a control apparatus, the control apparatus being electrically connected to the drive apparatus (20) and the pressure detection apparatus (200), and being arranged such that the pressure detection apparatus (200) transmits a first signal to the control apparatus when the pressure on the squeezing pusher (1) exceeds a predetermined value in order to control the action of the drive apparatus (200). The present fluid discharge system and the squeezing pusher thereof have little liquid discharge residue and convenient operation, and reduce the probability of accidental damage to a lining bag.
