It is also easy to produce wrinkle；Tension force deficiency, brings that the air capacity of film layer is excessive into, the density of parent roll film is small, and film is easily on tube core
Axial slip and serious dislocation are produced, so that cause that volume can not be unloaded.As parent roll diameter increases, if the rotating speed of wind-up roll
Still it is constant, then with the increase of winding linear velocity, necessarily cause being incremented by (because of what is sent out from draw-gear for winding tension
Film speed is constant), the interior loose outer tight of wound membrane is so not only resulted in, outer membrane crumples internal layer membrane, Er Qiefen
Also rewinding difficulty can be increased when cutting, influence to cut quality, therefore in order to avoid above-mentioned influence, the tube core of every kind of specification are carried
Film length be provided with limiting value, especially in lithium battery isolation membrane field, general a roll is at 1000 meters or so.But with lithium electricity
The wide range of industrial applications of pond barrier film, in the market is badly in need of the winding length of lifting film, in favor of industrial operation, for reality
This existing purpose, at present by increasing by one layer of resilient membrane on the surface of wind-up roll, to buffer influence caused by internal stress,
But it is this by way of increasing cushion in die surfaces, it also can only under equal conditions make film take-up length by 1000 meters
1500 meters or so are promoted to, improves limited extent, still can not meet commercial Application requirement, therefore a kind of energy of market in urgent need is bright
The technology of aobvious lifting film take-up length.
The content of the invention
In view of the above-mentioned problems existing in the prior art and the market demand, it is an object of the invention to provide one kind can be obviously improved film
The method for winding length.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of method for lifting film take-up length, methods described are during film take-up, are sent into the material as separate layer
Material, makes the material wound in film interlayer.
As a kind of embodiment, during film take-up, the storeroom as separate layer is every feeding winder.
As another embodiment, during film take-up, the material as separate layer is continuously introduced into winder.
Preferably, the material as separate layer is immalleable.
As further preferred scheme, the material as separate layer uses immalleable paper.
As further preferred scheme, for winding the die surfaces of film while being provided with cushion.
Compared to prior art, advantageous effects of the invention are：
On the one hand the present invention can offset the stress release of outer film in separate layer, obtain by setting separate layer in film interlayer
The film roll of surfacing, on the other hand, each separate layer can also play a supporting role simultaneously, equivalent to artificially adding
The external diameter of tube core is wound, so that collapsible film limiting length is improved, therefore passes through the layer of set separate layer
Number, can wind the film length of any requirement, can meet the various demands of commercial Application, have conspicuousness progress；In addition,
Because the separate layer set by the present invention is simply folded in film interlayer, when unreeling film, separate layer meeting self falling, no
Any influence can be produced on subsequent applications, therefore there is obvious practicality and industrial application value.
Brief description of the drawings

Fig. 2 is a kind of method schematic diagram for winding film provided by the invention；
Fig. 3 is the method schematic diagram of another winding film provided by the invention；
Fig. 4 is tube core structure schematic diagram of the present invention.
Label is schematically as follows in figure：1- films；2- tube cores；3- separate layers；4- cushions.
Embodiment
Technical scheme is described in further detail below in conjunction with drawings and examples.
As shown in Figure 1：It is wound on the outer surface of tube core 2, due to tube core 2 by film 1 when prior art winds film
Outside diameter d 1 fix, therefore when the film length of winding reaches the limiting value that tube core 2 is carried, the interior of wound membrane just occurs
Loose outer tight, outer membrane crumples internal layer membrane, and can also increase rewinding difficulty during cutting, the problems such as influenceing to cut quality,
So that collapsible film length is limited, it is impossible to over-limit condition.
Embodiment
With reference to shown in Fig. 2 and Fig. 3：In order to lift film take-up length, the present invention is by during film take-up, being sent into
As the material of separate layer 3, make the material wound in film interlayer, by setting separate layer 3 in film interlayer, on the one hand with
The stress release of outer film 1 in separate layer 3 is offset, obtains the film roll of surfacing, on the other hand, each separate layer 3
It can also play a supporting role simultaneously, equivalent to the external diameter of artificial increase winding tube core 2, so that the collapsible film limit is grown
Degree is improved.
A kind of embodiment, in the wrapup procedure of film 1, the storeroom as separate layer 3 is every feeding winder (such as Fig. 2
It is shown)；Another embodiment, in the wrapup procedure of film 1, the material as separate layer 3 is continuously introduced into winder (such as
Shown in Fig. 3).
Preferably, the material as separate layer 3 is immalleable, more preferably immalleable paper, with convenient retracted volume
With it is cost-effective.
As further preferred scheme, for winding the surface of tube core 2 of film 1 while being provided with cushion 4, to ensure to wind
