Description
Technical field
The invention belongs to the biaxial tension fields of film, are related to a kind of vertical machine drawing for polyester film biaxial tension and horizontal drawing
Long distance delivery device between machine.
Background technique
The principle of biaxially oriented polyester film: be by polyester fondant by extruder heating squeeze out be melt into slab after,
More than glass transition temperature, pass through vertical machine drawing (MDO) and transverse stretching machine within the scope of fusing point proper temperature below (under elastomeric state)
(TDO), under external force, the successively stretching with laterally progress certain multiple along longitudinal direction, to make the strand of polyester fondant
Or crystal plane is orientated and ordered arrangement on the direction for be parallel to thin film planar, and thermal finalization is then carried out under tension
The macromolecular structure of orientation is settled out, ideal polyester film most is made through cooling and subsequent processing afterwards.
In process of production, MDO is exported between TDO entrance there are certain transmission range, is entered when MDO is exported to TDO
When mouth distance is more than 3 meters, it is considered that sheet material is too long in the transmission range that MDO is exported between TDO entrance；Too long distance meeting
It directly results in sheet material and shakes the problems such as excessive, contained side amount fluctuation becomes larger and oblique pull occurs up and down, the quality of subsequent product is caused to become
Difference.
When MDO exports tension fluctuation, the processing method of the prior art is the whole tension values of middle control, and reverting to it can
It controls in range.This processing method must find simultaneously to handle in time in a short time, otherwise can generate to product thickness uncontrollable
The influence of system.When contained side amount is unstable, edge shake is excessive, be easy to happen it is de- clip broken film, such as TDO can occur for de- folder for a long time
There is the danger of a large amount of useless films and striker in inside, influences normally to produce.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of vertical machine drawing of biaxial tension
Long distance delivery device between transverse stretching machine is drawn when MDO is exported to the transmission range between TDO entrance greater than 3 meters vertical
Double S guide rollers are installed, control sheet material enters double S guide rollers, and the sheet material transmitted in double S guide rollers is between machine and transverse stretching machine
Relatively stable state, can effectively reduce the outlet MDO tension fluctuation, and in the outlet MDO, tension is very steady, effectively increases piece
The stability that material transports over long distances, relative to the sheet material transmission state before transformation, the present invention is exported between TDO entrance in MDO
The sheet material of transmission is shaken up and down, contained side amount fluctuates and there is a situation where oblique pulls to greatly improve.
Long distance delivery device between the vertical machine drawing of biaxial tension and transverse stretching machine, in the vertical machine drawing of long range and transverse stretching machine
Between double S guide rollers conveyings are set, double S guide rollers are symmetrical two groups of S guide rollers, are separately positioned on vertical machine drawing side and horizontal
