Abstract
The utility model discloses a kind of inflatable core for improving film planarization, its drip irrigation device includes core main body, inflatable layer in the core main body, described inflatable layer tight is in core main body, wrap up a layer thickness about 1~3mm plastic protective layers in the inflatable layer periphery, the utility model has the advantage of by the way that inflatable mechanism is combined with conventional core, the adjustable of core circumferential size within the specific limits can be realized, apply in film take-up, the inconsistent phenomenon of film surface tensioning degree that stress in thin films changes over time and cause can be tackled well, improve the planarization of film surface.
Description
Technical field
The utility model is related to a kind of film bobbin, more specifically, it relates to a kind of inflatable for improving film planarization
Core.
Background technology
Generally continuously wound using cylindric papery or plastics core during film take-up.Because film is in core
Continuous winding, and film material can exist in its preparation process the film after certain internal stress, therefore winding with when
Between passage, internal stress can slowly discharge, and finally be possible to cause film surface because internal stresses release is uneven and occurs
A series of out-of-flatness phenomenon.The film of out-of-flatness, is particularly applied to the barrier film among lithium ion battery, can be used for
Performance is produced and had a strong impact on, or even can trigger a series of security incidents, it is therefore desirable to avoided caused by this stress release not
Planarization.In order that the stress in thin films after winding is slowly uniformly discharged, it is necessary to a kind of specially designed core, its circumferencial direction
Size stress in thin films discharge during can have certain adjusting range, enable adaptation to stress in thin films release
During film surface planarization change, it is ensured that film surface it is smooth.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of gas for improving film planarization
Swollen core.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of inflatable volume for improving film planarization
Inflatable layer in core, including core main body, the core main body, the inflatable layer tight is in core main body, the inflatable layer
A layer thickness is wrapped up for 1~3mm plastic protective layers in periphery.
As preferred, the plastic protective layer is made up of thermoplastic of the shore hardness between 40~60.
As preferred, the thermoplastic is soft polyethylene, soft PVC, ethene-vinyl acetate copolymerization
Thing, TPUE, thermoplastic polyester elastomer, thermoplastic polyolefin elastomer, thermoplastic styrene elastomer
In one kind.
The utility model is compared compared with the prior art to be had：The present invention, can by the way that inflatable mechanism is combined with conventional core
To realize the adjustable of core circumferential size within the specific limits, apply in film take-up, film can be tackled well
The inconsistent phenomenon of film surface tensioning degree that internal stress is changed over time and caused, improves the planarization of film surface.
Brief description of the drawings
Fig. 1 is the structural representation for the inflatable core embodiment that the utility model improves film planarization.
In figure：1st, core main body；2nd, inflatable layer；3rd, plastic protective layer.
Embodiment
The embodiment for improving the inflatable core of film planarization to the utility model below in conjunction with the accompanying drawings is described further.
Inflatable layer 2 in a kind of inflatable core for improving film planarization, including core main body 1, core main body 1, inflatable layer 2
Tight wraps up a layer thickness about 1~3mm plastic protective layers 3 in core main body 1,2 periphery of inflatable layer.Contain inflatable structure
Core, core main body 1 is made up of the cylinder of papery material or plastic material, and inflatable layer 2 is close by tight fit and core main body 1
A layer thickness is wrapped up for 1~3mm plastic protective layers 3 in connection, 2 periphery of inflatable layer.The plastic protective layer 3 is 40 by shore hardness
Thermoplastic composition between~60.By the way that inflatable mechanism is combined with conventional core, it is possible to achieve core circumferential size exists
A range of adjustable, is applied in film take-up, stress in thin films can be tackled well and be changed over time and make
Into the inconsistent phenomenon of film surface tensioning degree, improve the planarization of film surface.
Plastic protective layer 3 is made up of thermoplastic of the shore hardness between 40~60.Thermoplastic is soft
Polyethylene, soft PVC, ethylene-vinyl acetate copolymer, TPUE, thermoplastic polyester elastomer,
One kind in thermoplastic polyolefin elastomer, thermoplastic styrene elastomer.These materials all have good elasticity and can
Effectively the film in core main body 1 is contacted, and these material smoothness are higher, abrasion will not be caused to film.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model, should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
