Description
Technical field
The present invention relates to plastic film production field, vane device is used in specifically blow molding.
Background technique
With the progress of mankind's science and technology, plastic film has substituted most of papery packaging, the demand of film as packaging
Measure huge, the molding of film when using this method, after plastic material melt in extruder, can be passed through using flat crowded upper blowing method
It crosses the runner formed between the handpiece body of blow molding machine head and mold core and the raw material of melting is extruded into thin-wall tube, then using pressure
Contracting air carries out inflation to thin-wall tube and forms film tube, and film tube is cooled down by vane device at the same time, has cooled down
Film tube, by the flat film for forming fitting of folder, will be carried out using collapser finally by traction roller on packaging film feeding to wind-up roll
Winding.
Vane device in existing production generally uses single air port vane device, but using the cooling of single air port vane device
Efficiency is lower, and the Chinese utility model patent that notification number is CN206884159U in the prior art has issued for a kind of degrade and blows
The double air port vanes of film machine, there are two air outlet, the cold airs and film of the blowout of two air outlets for the vane device tool in the patent
The contact area of pipe is bigger, so cooling efficiency is higher, while two air outlets are blowed film tube from different location and make
The cooling for obtaining film tube is more uniform.
Although technical solution in the patent solves the problems, such as that cooling efficiency is lower, but there is also following for the technical solution
Problem:
First, in actual production, it is often necessary to the film tube of different-diameter is produced according to different needs, and it is different straight
Requirement of the film tube of diameter to cold air blowout angle be not identical, and two air outlets are fixed in the technical solution, so
The angle of cold air blowout is fixed always, is unable to satisfy the need that film tube under different-diameter blows out cold air difference angle
It asks.
Second, air outlet position is chronically at opening-wide state, and dust is easy to enter the interior of vane device by air outlet
Portion, the dust that is accumulated in inside vane device of going down for a long time can be driven by cold air and blow to film tube, on the one hand, write finish so that
Dust is stained on film tube, on the other hand, the presence of dust will affect the uniformity of cold air blowout, in turn result in film tube
Inhomogeneous cooling is even, is unfavorable for the promotion of film quality.
Third, Chinese summer indoor and outdoor temperature is higher, and cold air required for film tube is cooling at this time is more, and
Winter indoor and outdoor temperature is relatively low, and cold air required for film tube is cooling at this time is less；Thus at a temperature of varying environment, film
Cold air air quantity required for pipe is cooling is different, but the cold air of the technical solution is after air outlet blowout, cold air one
Aspect sheds by heat release hole, on the one hand continues to blow on film tube and cools down, because heat dissipation pore size can not adjust, so that blowing
The air quantity accounting of cold air on to film tube is fixed, thus is unable to satisfy at a temperature of varying environment to blowing to film tube
Cold air air quantity demand.
Summary of the invention
The invention is intended to provide blow molding vane device, with solve in the prior art air outlet blowout cold air angle without
Method adjusts the problem of with vane inside dust accumulation.
In order to achieve the above object, base case of the invention is as follows: blow molding vane device, packet wind are tried to get to the heart of a matter seat and windward
Disk, windward disk cover are tried to get to the heart of a matter on seat in wind, and leeward lip is fixedly connected on windward disk, and wind is tried to get to the heart of a matter between seat, windward disk and leeward lip

Specific implementation process is as follows:
When blow moulding machine does not work, turntable 16 is rotated by push handle 21, so that adjusting the sliding of 13 downward spiral of ring, is made simultaneously
It obtains first through hole 14 not to be connected to the first upper air duct 8, the second through-hole 15 is not also connected to the second upper air duct 9, i.e., by adjusting ring
13 make the first upper air duct 8 and the second upper air duct 9 that can not blow out cold air, it is ensured that dust will not pass through 8 He of the first upper air duct
Second upper air duct 9 enters in annular main air duct 5, to reduce the entrance of dust in vane device.
In blow moulding machine work, if the angle of the cold air of the first upper air duct 8 blowout is suitble to the cooling of film tube 23 to need
It asks, then turntable 16 is rotated by push handle 21, so that first through hole 14 is directed at the first upper air duct 8, cold air stream is through annular main air duct
5, the first aperture 11, first through hole 14 are blown out eventually by the first upper air duct 8, and then realize the cooling effect to film tube 23.
Similarly, if the angle changing rate of the cold air of the second upper air duct 9 blowout is suitble to the cooling requirement of film tube 23, then lead to
It crosses push handle 21 and rotates turntable 16, so that the second through-hole 15 is directed at the second upper air duct 9, then cold air is blown out from the second upper air duct 9, into
And realize the cooling effect to film tube 23.
Meanwhile lower air duct 7 is in long-term opening-wide state, thus the wind in annular main air duct 5 can be blown by lower air duct 7
Out, upper air duct combination lower air duct 7 can be improved the cooling efficiency to film tube 23 while make the cooling of film tube 23 more equal
It is even.
By rotating turntable 16, the selection to the first upper air duct 8 or the second upper air duct 9 is realized, and then meet different-diameter
Demand of the film tube 23 for cold air air outlet angle.
The rotation that exogenous wind lip 18 and the intermediate wind lip 17 in of wind lip 19 are adjusted by push handle 21, to realize to cold sky
The purpose that air-blowing is adjusted to the air quantity of film tube 23, and then meet at a temperature of varying environment to the cold air wind for blowing to film tube 23
Amount demand.
