Title Contact and convert film winder
Abstract
Through analysing the contact and conversion film winder,
s functions
and characteristics and sclaning large amounts of data,the contact and
convert film winder,
s overall structural design were formulated. Firstly,the
AC frequency reduction machine can make the roller speed adjustable.
Secondly,electro-hydraulic proportional hydraulic system can make the
pressure between the winding roller and the drive roller constant and films
turn convert. Thirdly,both at ends of the drive roller, the aligning ball
bearings was installed to eliminate the housing bore concentricity error,
installation error ,flexural deformation, and other factors effects which
affect the parallel of drive roller and the winding roller.
Forthly,cylinder locking the shaft bearing outer ring to exchange the film
roll-changing easyly. Fifly, the location of the major components wered
made out by the mapping method,whcih provided the design basis and
foundation for institutional size calculation and 3D design work. Finally,
using Solidworks 3D modeling to draw two-dimensional drawings.
