Description
Technical field
The utility model belongs to the technical field of film take-up more particularly to a kind of changing for film surface winding device
Roll up mechanism.
Background technology
The angle that power resources are batched from film distinguishes, and film take-up form can be divided into three kinds:During the first is
The heart is wound, and as its name suggests, the power of film roll rotation is directly from the Scroll positioned at film roll center, and Scroll is then by motor
Directly drive；It is for second surface winding, as its name suggests, the power of film roll rotation arises directly to be contacted with film roll surface
Mantle friction roller, mantle friction roll-in implement mantle friction rubbing on film roll surface and to film roll, and mantle friction roller is straight by motor
Tape splicing is dynamic；The third is surface and center winding, and as its name suggests, the rotation of film roll has both two kinds of power（Surface power is in
Power aroused in interest）.
In the wrapup procedure of surface, Scroll, which can be moved forward and backward, movably to be installed on Scroll sliding support, when Scroll moves
It moves when actually can carry out batching the position of work, the location of Scroll is known as take-up position.When in take-up position
After the film that Scroll batches reaches setting length, it is necessary to change new Scroll, this process is known as change of lap.New Scroll
Before being not moved to take-up position, it is necessary to be previously positioned on spare space, the Scroll for being placed on spare space is referred to as spare
Scroll.When change of lap starts, spare Scroll is moved to take-up position from spare space.
The coil replacing mechanism of conventional films surface winding device has the disadvantage that：When change of lap starts, spare Scroll just
When being moved to take-up position, just contact surface friction roller and film, the initial velocity of spare Scroll rotation is zero, and thin at this time
The operation of film does not stop but, front do not have to the drag of film it is tranquil, thus initial velocity be zero Scroll just be just expert at
Into film contacts when, film will be formed be similar to pin, the effect stopped of stopping, cause the pulling force that film is subject to become larger suddenly,
If film thickness than relatively thin, is easy for causing film by the uneven problem in tear fracture, deformation, fold, end face.
