AI Technical Summary

Technical Problem

Traditional sterilization cups rely on multiple tightening screws for point-by-point adjustment, which is time-consuming and prone to sealing failure or needle collision due to uneven force.

Method used

The design employs a guide block and adjusting rod structure, which enables the sterilization cup to be raised and lowered through the linear movement of the guide block. Combined with the design of dovetail grooves and indexing pins, it achieves stable compression and rapid positioning of the sealing ring, and uses a quick-connect fitting structure.

Benefits of technology

The operation process of the sterilization cup has been simplified, and uniform force sealing has been achieved to prevent the sealing ring from coming out, thus improving the installation efficiency and reliability of the sterilization cup.

Abstract

The utility model relates to a blow -fill -seal equipment technical field discloses a sterilization cup subassembly of blow -fill -seal equipment, sterilization cup main part has the accommodation cavity, and the needle is inserted into the accommodation cavity and goes down, and the adjusting mechanism includes adjusting lever, guide seat, guide block and adjusting lever fixed block and installs the sterilization cup mounting seat on the surface of sterilization cup main part. The sterilization cup subassembly of blow -fill -seal equipment moves through the setting adjusting lever and pushes the guide block, indirectly makes the up-and-down movement of sterilization cup main part, when the upward movement, the contact surface of compactor and extruder mould is compacted, forms the sealed environment, compares the operation of multiple jackscrews of current multiple jackscrews, is different from the multiple jackscrew scheme of conventional, adjusts the jackscrew one by one to realize the lifting of sterilization cup, here only needs to adjust an adjusting lever, can use the linear motion of guide block to realize the lifting of sterilization cup, and the operation is simple, and the stress is even.
