Abstract

The invention relates to a softness screen material sealing intensity tester, which is composed of a PLC, an input / output device connected with the PLC and a testing main machine body; the testing main machine body comprises a stander, a main fixture and an auxiliary fixture which are arranged on the stander and the displacement of the main fixture and the auxiliary fixture is controlled by the PLC; the main fixture comprises of an upper fixture and a lower fixture; the upper fixture and the lower fixture are two gad tongs which can clamp a test specimen; the mouths of the gad gongs are in the same plane which is parallel to the centre of a screw rod; the upper fixture is connected with a sensor; the lower fixture is also provided with a displacement pickup. The auxiliary fixture is a setof gad tongs which can be regulated in multiaspect. The device is designed and manufactured according to the testing requirements related to the sealing intensity of softness protective screen materials in EN868-1 the medical appliance packing material needing sterilizing and the system. The tester has simple detecting operation, good accuracy and high efficiency.

Description

technical field [0001] The invention relates to the technical field of material sealing strength detection, in particular to a soft barrier material sealing strength tester. Background technique [0002] The main materials for sterilization packaging of medical devices are Paper-Poly Pouch, PolyPouch, Medical-Grade Paper with excellent air permeability, and Form-Filled Film. Blister box (Tray) and the most characteristic material for medical device packaging. [0003] Medical device sterilization packaging also belongs to the category of flexible packaging with paper-plastic materials as the main body, and its important difference is that medical device products have very high requirements for packaging materials, in addition to meeting the basic packaging for conventional protection and isolation from the external environment In addition to performance, more emphasis is placed on the continuous stability of material performance, as well as the compatibility with sterilizat...
