Machine for testing cushioning material for packaging

摘要

The invention relates to a machine for testing cushioning material for packaging, which improves the test method and performs a more precise characterization of cushioning for packaging. The machine is formed by: a load arm (1); a lift motor (2) on the upper part thereof; several guides that connect (i) a rigid platform (6) for positioning the sample to be tested, replaceable by a load cell (6′), and (ii) an impact platform comprising sensors (7) for monitoring the position thereof and measuring acceleration during impact; a spindle (4) for moving the load arm; and, on the lower part thereof, a seismic mass (5) for reducing the transmission of the impact.

主权项

1. Machine for testing cushioning material for packaging wherein said machine configured to be displaced by a spindle, comprising:
a lifting motor at an upper part of a machine; a plurality of guides extended between said lifting motor and a support platform located on a seismic mass; a lightweight impact platform and a heavyweight impact platform each slideably movable on said plurality of guides; a loading arm mechanically connected to a spindle extended between said lifting motor and said support platform and adapted to load said lightweight impact platform and said heavyweight impact platform; a release mechanism adapted to actuate said loading arm for releasing said lightweight impact platform while said heavyweight impact platform remains loaded on said loading arm and to move said loading arm for releasing said heavyweight impact platform when said lightweight impact platform is not in place; a plurality of sensors for monitoring a position of said lightweight impact platform and said heavyweight impact platform and for measuring an acceleration of said lightweight impact platform and said heavyweight impact platform during impact; wherein each of said plurality of sensors is attached to at least one of said lightweight impact platform and said heavyweight impact platform; and wherein said seismic mass is configured for reducing a transmission of the impact.
