Claims6
A double-roller hose pressing apparatus for a peristaltic pump, —comprising two flexible-rolling rollers respectively disposed at two sides of a working hose in the peristaltic pump, wherein the two rollers are configured for pressing a working hose, and the two rollers are arranged in relative positions to clamp the working hose during operation,
- wherein the two rollers configured for pressing the working hose are both movable hose-pressing roller assemblies, and the two movable hose-pressing roller assemblies clamp the working hose by synchronized swinging motion towards each other,
- wherein each of the movable hose-pressing roller assemblies comprises a roller component, an eccentric crankshaft, a synchronizing gear, a driven spiral gear and a driving spiral gear;
- each roller component is arranged at one end of its respective eccentric crankshaft each driven spiral gear and synchronizing gear are arranged on their respective eccentric crankshaft each eccentric crankshaft swings by coordination between its driving spiral gear and driven spiral gear;
- and the roller components of the two movable hose-pressing roller assemblies rotate synchronously by the synchronizing gears.
