Description
Technical field
The present invention relates to film blowing device technical fields, and in particular to a kind of cooling device of film blowing device.
Background technology
In the production process of plastic packaging film, it is processed production frequently with inflation film manufacturing machine, by molten resin material by mould
The extrusion of head is squeezed out and is lifted upward, makes the hotting mask base of extrusion by cold by the uniform blowing cold air of vane in the process
But, the elastomeric state tubular film bubble for forming form relative securement, in the cooling procedure of film base, especially near extrusion
The more soft viscous state film base of one section of quality, needs the pressure, flow velocity and the uniformity that control rational air-flow, avoids vane defeated
The irregular air-flow gone out causes modal influence to the extrusion zone of film base；In addition, conventional single air duct vane is in blowout air-flow
After being cooled down to film base, for the film base close to viscous state section below frost line, it is difficult to be cooled down to it by air-flow, need to lead to
For toning high gas flow pressure with flow velocity to improve the mode that air-flow blows out height, the high-speed flow of big flow be easy to cause extrusion
Nearby the first viscous state film base for squeezing out just extrusion is pressurized excessive, brings film bubble form unstable or the bad shadow torn occurs in film bubble
It rings.
Invention content
The purpose of the present invention is to provide a kind of cooling devices of film blowing device, and air-flow is carried out to wind turbine by air feed pedestal
Pre- shunting supplies to each air duct and provides more constant multi-faceted air-flow to annular main air duct, through outlet air regulation ring one, two
It is lower viscous especially just to squeeze out stability to the uniform air flow provided in improvement film base for the air-flow velocity of grade annular passage
While the cooling stability of fluidised form film base, and the molding effect of the film base close to frost line part is made to be improved.
To achieve the above object, the present invention is implemented using following technological means：
A kind of cooling device of film blowing device, including air feed pedestal, vane, air duct, air feed pedestal centre are provided with court
Air feed entrance upward supplies annular flow through diversion mechanism to air feed pedestal inner cavity, and air duct uniform ring is set around air feed pedestal
Air feed pedestal inner cavity and annular main air duct are set and connect, annular main air duct shunts inwardly forms the level-one of outlet upward
Annular passage and two level annular passage, level-one, two level annular ducting outlet mutually collect, and level-one annular passage entrance is in ingate
Battle array circumference is set to outlet air regulation ring, and is interconnected between two level annular passage, and outlet air regulation ring only adjusts two level annular
The space size in air duct and the flow velocity for adjusting I and II annular passage simultaneously, outlet air regulation ring are provided with closing two level annular wind
The enclosed construction in road, annular main air duct is directly supplied to level-one annular passage under closed state.
Further, the diversion mechanism includes the taper platform conllinear with air feed entrance axial line, annular flow distribution plate, ring
The pointed end of shape baffle, the taper platform of air feed pedestal inner cavity roof is directed toward air feed entrance center, air feed pedestal bottom wall of inner cavity
Tap hole is uniformly arranged on annular flow distribution plate, annular shunting plate part encloses taper platform, the annular gear of air feed pedestal inner cavity roof
Plate part encloses annular flow distribution plate, and air feed tube inlet is located at air feed pedestal side wall upper limb and is directed toward ring baffle.

Such as Fig. 2-3, it is preferred that the upward bending of 2 innermost circle of vane bottom cover forms central ring wall 23, with die head running-on
It is enclosed between the internal ring wall 61 that the upward bending of 6 innermost circles is formed, forms level-one annular passage 81 and export, the internal ring wall 61 is high
Degree is less than central ring wall 23, and with this configuration, level-one annular passage 81 exports the air-flow presentation blown out from bottom to top and flows slightly inwards
Dynamic air-flow can inwardly be blown out to just squeezing out the lower viscous state film base of stability, avoid itself and internal ring wall 61, central ring wall
Occurs the phenomenon that adhesion between 23；
In addition, further, the upward bending of 5 innermost circle of outlet air regulation ring forms external annulus 52, with central ring wall 23
Between enclose, form two level annular passage 82 and export, 23 height of central ring wall is less than external annulus 52, by the setting,
Effectively tentatively cooling viscous state film base can be blown out inwardly, it is avoided to occur between central ring wall 23, external annulus 52
The phenomenon that adhesion；And the air-flow of fair speed is when flowing through external annulus 52, and it is inwardly directed by external annulus 52, in same air flow rate
Under, so that air-flow is obtained higher climb, the molding effect of the film base close to frost line part is made to be improved.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
Subject to.
