Measurement apparatus for measuring a relationship between a degree of cure and a specific volume of a packaging material
First Claim
1. An apparatus for measuring a relationship between a degree of cure and a specific volume of a packaging material, the apparatus comprising:
- an upper load module provided at a top of the apparatus and including an upper servo motor, an upper ball screw and a force plate, with the upper servo motor configured for driving the upper ball screw into rotation via a belt, such that the force plate coupled to the upper ball screw moves downward to be positioned in place;
a lower load module provided at a bottom of the apparatus and including a lower servo motor, a lower ball screw and a load joint group having a push rod, with the lower ball screw configured for being driven by operations of the lower servo motor, such that the load joint group coupled to the lower ball screw creates a corresponding displacement;
an upper film cavity module coupled to the force plate of the upper load module; and
a lower film cavity module provided on the lower load module for partially and slidably receiving the push rod of the load joint group, with the push rod configured for moving up with the displacement of the load joint group, wherein the lower film cavity module includes a cavity and a heating pipe configured for heating and maintaining a subject to be measured in the cavity at a constant temperature,wherein the upper load module is configured for moving down through the force plate and the push rod is configured for moving up in the lower film cavity module, such that a constant pressure is applied to the subject to be measured in the cavity, and a change in volume per unit time of the subject to be measured is measured by an optical measuring unit provided on the lower load module near the cavity.

Abstract
An apparatus for measuring a degree of cure and a specific volume of a packaging material is provided, including: an upper load module configured for driving the rotation of an upper ball screw via an upper servo motor such that a force plate coupled to the upper ball screw moves downward and is thus positioned; a lower load module having a lower ball screw operating and moving via a lower servo motor such that a load joint group connected to the lower ball screw generates a corresponding displacement; an upper film cavity module connected to the upper load module; and a lower film cavity module disposed on the lower load module. The displacement of the load joint group enables a push rod to move upward. A heating pipe keeps constant the temperature of a subject to be measured in a cavity of the lower film cavity module.
