Description
Technical field
A kind of thin film processing techniques are the utility model is related to, more particularly to a kind of protective film blowing head.
Background technology
At present, existing plastic film blow moulding machine upper die head generally includes inner mould head and outer die, and plastic raw materials are in pressure
The lower gap extrusion by between inner mould head and outer die of effect is in annular membrane tube in uniform thickness, then appropriate compressed air is blown
Enter in membrane tube, make its radial direction inflation, cold wind is blowed to membrane tube positioned at exterior cooling system is allowed to cool to carry out subsequent job.
Cooling duct and the molding machine separation of this kind of mould head of blow-moulding machine, can frequently result in protective film molding thickness and differ,
And the phenomenon of fracture often occurs in forming process, the quality of production is poor.
Utility model content
The utility model is simple in structure mainly solving the technical problems that provide a kind of protective film blowing head, can
Easily realize the blow molding of protective film, and the whole forming process of protective film under the blowing of blow head along molding sleeve
Shaping downwards, improves obtained protection film quality.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of protective film is provided with blowing
Mold head, including：Outer die and inner mould head, offer cricoid formed pipe between the outer die and the inner mould head,
The inside of the outer die offers the distinguished and admirable road of annular, and the bottom in the distinguished and admirable road is provided with multiple air blowings evenly distributedly
Head, the inner mould head are externally connected to molding sleeve, and the mouthpiece of each blow head is directed at the molding sleeve surface, realizes institute
The pyrosol flowed out in formed pipe is stated to be cooled and shaped gradually downward along the molding sleeve surface.
In one preferred embodiment of the utility model, the molding sleeve is stainless steel.
In one preferred embodiment of the utility model, the upper end in the distinguished and admirable road is also associated with blast pipe, the inlet air
The extraneous wind turbine of pipe connection.
In one preferred embodiment of the utility model, to be detachably connected between the molding sleeve and the inner mould head,
It can be easy to the maintenance and replacement of molding sleeve.
The beneficial effects of the utility model are：A kind of protective film blowing head of the utility model, by using in external mold
Distinguished and admirable road is opened up in head, blow head is connected in the lower end in distinguished and admirable road, while jacket is mounted in the outer surface of inner mould head, can be made
High temperature feedstock is obtained when formed pipe flows out, can be progressively cooled to downwards along molding sleeve surface under the action of blow head
Type, can effectively prevent film breaks, greatly improve the quality of production.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model in a preferred embodiment；
The mark of each component is as follows in attached drawing：1st, outer die, 2, inner mould head, 3, formed pipe, 4, distinguished and admirable road, 5, blow
Head, 6, blast pipe, 7, molding sleeve.
Embodiment
The preferred embodiment to the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make the scope of protection of the utility model apparent clear and definite
Define.
Referring to Fig. 1, the utility model embodiment includes：
A kind of protective film blowing head, including：Outer die 1 and inner mould head 2, the outer die 1 and the inner mould head 2
Between offer cricoid formed pipe 3, the inside of the outer die 1 offers the distinguished and admirable road 4 of annular, the distinguished and admirable road 4
Bottom is provided with multiple blow heads 5 evenly distributedly, and the inner mould head 2 is externally connected to molding sleeve 7, each blow head
5 mouthpiece is directed at 7 surface of molding sleeve, realizes the pyrosol that is flowed out in the formed pipe 3 along the molding sleeve 7
Surface is cooled and shaped gradually downward.
Wherein, the molding sleeve 7 is stainless steel.
The upper end in the distinguished and admirable road 4 is also associated with blast pipe 6, and the blast pipe 6 connects extraneous wind turbine.
To be detachably connected between the molding sleeve 7 and the inner mould head 2, the maintenance and replacement of molding sleeve 7 can be easy to.
The utility model discloses a kind of protective film blowing head, its specific use principle is：High temperature feedstock is being pressed
Enter under the action of power in formed pipe 3 between outer die 1 and inner mould head 2, at the same time, start extraneous wind turbine, by into
The aweather supply cooling wind in runner 4 of air hose 6, is then gone out by blow head 5 by wind is cooled down, progressively downward with high temperature feedstock
Flowing, the cooling wind that blow head 5 sprays equably dispels high temperature feedstock to 7 surface of molding sleeve, so that straight on 7 surface of molding sleeve
Connect and be cooled into protective film.
The prior art is different from, a kind of protective film blowing head of the utility model, opens up by using in outer die 1
Distinguished and admirable road 4, blow head 5 is connected in the lower end in distinguished and admirable road, while is mounted to jacket 7 in the outer surface of inner mould head 2, enables to height
Warm raw material can be progressively cooled to downwards when formed pipe 3 flows out under the action of blow head 5 along 7 surface of molding sleeve
Type, can effectively prevent film breaks, greatly improve the quality of production.
, it is necessary to explanation, term " on ", " under ", "left", "right", " interior ", " outer " etc. in the description of the utility model
The orientation or position relationship of instruction be based on orientation shown in the drawings or position relationship, or the utility model product use when
The orientation or position relationship usually put, are for only for ease of description the utility model and simplify description, rather than instruction or dark
Show that the die head of meaning or element there must be specific orientation, with specific azimuth configuration and operation, thus it is it is not intended that right
The limitation of the utility model.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
