The problem existing in the gripper part of the
boxing machine is analyzed to put forward a design of
bidirectional-regulation gripper mechanism, to carry out the
design of pneumatic and mechanical part and to specifically
illustrate the structure composition, operating principle and
packing technology of the mechanism. The result shows that
the bidirectional-regulation gripper mechanism can properly
adjust the space and pack conveniently for round bottles,
unusual bottles, lump material or small-bag packing material
and such kind of orderly and regular packaging container. It
has a better packing effect, a higher space utilization rate, a
safer transportation than one-way regulation gripper
mechanism. It has a high engineering
