Description
Technical field
The present invention relates to thin film technique fields more particularly to one kind can improve the winding corrugated method of thin film bottoming.
Background technique
The major function of winder is the later period will to be facilitated to cut by the wide-range film after biaxial tension in steel shaft
It uses.Winding is continual winding mode, as shown in Figure 1.Since speed is very fast, by the guidance of roll 1 and guide roller 2,
Winder winds film, wherein the steel shaft 4,7 of winder be mounted on winding capstan head 9 on and with winding capstan head 9 rotation with
It realizes and alternately replaces, guarantee that main line uninterruptedly produces.When change of lap, the steel shaft 7 for being wound with film leaves pressure roller 3 and by auxiliary last item
6 compress, and with the rotation of winding capstan head 9, empty steel shaft 4 enters winding position, since the presence of electrostatic rod 8 makes band on film
Head are attached in steel shaft 4 by high-pressure electrostatic at once after having electrostatic, lateral cutter to cut off film continues winding production.
Film is after being adsorbed onto steel shaft 4, the problem of moment may be because of the transformation and cutter angle of tension, the pressure roller in figure
Fold is squeezed out between 3 and 4 roller of steel shaft, film is caused to occur numerous quality problems in Downstream processing, such as: inner ring
Lateral ripple glaze, tension is unstable or bottoming flatness is bad, will lead to big axis inner ring out-of-flatness, forms lateral ripple glaze,
Monolithic film surface out-of-flatness, will lead to client and is not available, and reduce the utilization rate of film.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of improvement winders to wind the corrugated method of thin film bottoming,
It can solve the buckling problems that film occurs when change of lap very well, improve the winding performance of winder.
In order to solve the above technical problems, the technical scheme is that
A kind of improvement winder winding corrugated method of thin film bottoming, the tension of film when setting winder is normally wound
Value is F1, and the pressure value between pressure roller and the spool of stretch wrap film is F2；It first will be under the pressure between pressure roller and spool when change of lap
Adjusting in 50%~70% and reel change maintains the pressure between pressure roller and spool constant；After change of lap, it is gradually increased pressure roller
Pressure between spool is up to the pressure recovery between pressure roller and core roller to F2.
Above-mentioned improvement winder winds the corrugated method of thin film bottoming, after change of lap, the pressure between pressure roller and spool
Force value is gradually raised with the 5%~15% of F2 for gradient.
Above-mentioned improvement winder winds the corrugated method of thin film bottoming, when change of lap first by the tension up-regulation 30% of film~
50%, and maintain the tension of film constant in reel change；It is F1 by the tension adjustment of film after change of lap.
Above-mentioned improvement winder winds the corrugated method of thin film bottoming, adds electrostatic adsorption bar, the electrostatic adsorption bar
The place for being located at pressure roller downstream on film direction of transfer and closing on film is set, and the voltage of the electrostatic adsorption bar is 40KV
~45KV.
Above-mentioned improvement winder winds the corrugated method of thin film bottoming, and the voltage of the electrostatic adsorption bar is 40KV.
Above-mentioned improvement winder winds the corrugated method of thin film bottoming, and the thickness of film is less than or equal to 50um.
The present invention is to improve winder to wind performance, in conjunction with the adjustment of change of lap tension, pressure and Electrostatic Absorption voltage, into
And optimize bottoming flat conditions in reel change, when effective solution change of lap in empty reel spool the problem of film bottoming corrugation.This
Invention effect is good, easy to operate；It ensure that the planarization of winding bottoming, reduce bottoming loss, reduce production cost, improve enterprise
The economic benefit of industry.
Detailed description of the invention
Fig. 1 is the system schematic of winder.
Specific embodiment
The present invention sets the tension value of film when winder is normally wound as F1, between pressure roller and the spool of stretch wrap film
Pressure value is F2；The pressure between pressure roller and spool is first lowered into 50%~70%, i.e. pressure between pressure roller and spool when change of lap
Power is reduced to 0.3~0.5 times of F2；And maintain the pressure between pressure roller and spool constant in reel change；After change of lap, by
Pressure between cumulative large pressuring roller and spool is up to the pressure recovery between pressure roller and core roller to F2.
The method for reducing pressure between pressure roller and spool when passing through change of lap is verified well in practice, and effect compares
Obviously, but due in reel change tension it is inadequate, film there is also the oblique of local single once in a while and crease.In order to more preferable
Realization change of lap when film bottoming effect, the tension of film first can be raised 30%~50% when change of lap starts, i.e. film
Tension is 1.3~1.5 times of F1；And maintain the tension constant in reel change, after change of lap, it is by the tension adjustment of film
F1 almost seldom sees oblique single after this and creases,
In the prior art, winder further includes being located at pressure roller downstream on film direction of transfer and closing on the quiet of film setting
The voltage value of Electro Sorb stick, electrostatic adsorption bar is usually set to 45KV~50KV, in order to enable film can be in change of lap by it
Tension is evened up, and the voltage of the electrostatic adsorption bar is 40KV~45KV, it is preferred that the voltage of the electrostatic adsorption bar is 40KV.
It is less than or equal to the film of 50um for thickness, the using effect of the above method is more preferable.
