AI Technical Summary

Technical Problem

In the existing soft capsule packaging machines, when the plunger of the syringe pump is adjusted, the amount of filling injected by each individual plunger cannot be independently adjusted, resulting in large variation in the weight of the capsule and affecting the quality of the finished product.

Method used

A plunger with an axially deployed structure is designed, including a tip, a sealing body, a fixed mechanical butt ring, a plunger stopper shell, an axially adjustable mechanical butt ring, a mechanical pin and a adjuster nut. By adjusting the axial position of the second mechanical butt ring, the independent stroke of each individual plunger is achieved.

Benefits of technology

By independently adjusting the stroke of each individual plunger, it can effectively compensate for the mechanical variables in the physiological system variation, reduce the variability of the filler weight in the soft capsule, and improve the quality of the finished product.

Abstract

The present invention describes a plunger, which is configured to be used in a syringe pump of a machine for encapsulating soft capsules, for adjusting the amount of filler to be injected into the soft capsules, the plunger having an axially expanded structure and comprising: a tip (31) and a sealing body (32) connected to the tip, which is suitable for penetrating into the syringe pump (P), a first fixedly positioned mechanical docking ring (33) connected to the sealing body, a plunger stopper housing (34) connected to the fixedly positioned mechanical docking ring, an axially adjustable second mechanical docking ring (35), a mechanical pin (37) protruding from the stopper housing, and an adjuster nut (36) suitable for being screwed on the mechanical pin (37) for adjusting the axial position of the second ring (35) relative to the first ring, so as to adjust the axial position of the plunger in the syringe pump (P).
