Description
Technical field
The present invention relates to injection molding art, particularly relate to a kind of blowing vane structure of plastic sheeting.
Background technology
Plastic film blowing machine mostly adopts upper blowing method to produce, and is provided with cooling vane at head upper, is equipped with annular passage in each cooling vane, is generally provided with multiple opening direction air outlet upward inside annular passage.In process of production, plastics melt flows out from head and forms film bubble, film bubble is pulled and constantly moves upward, the cooling vane being positioned at film bubble periphery then constantly blows out high velocity air upwards, high velocity air plays cooling and the effect such as stable to film bubble, and meanwhile, the high velocity air of cooling vane also can traction ambient air, formed so-called " underbalance effect ", thus contribute to the inflation of film bubble.
As everyone knows, the cooling effect of cooling vane all has a significant effect for the quality of production of film and speed of production, and the cooling velocity of cooling vane directly limit the speed of production of film.The current cooling device for film bubble mainly adopts air-cooler cold wind to be blown into the outer vane of die head of film blowing machine, and carry out external refrigeration to film bubble, its weak point is: air-out is uneven, and air-out blast is high, power consumption is large, and cooling effect is poor, uneven film thickness is even, and film clarity is poor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of blowing vane structure of plastic sheeting, makes air-out even, and the film thickness of blowout is even, thus improves cooling effect, reduces energy consumption, adds film clarity, improve product quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the blowing vane structure providing a kind of plastic sheeting, comprise: outer vane, wind bowl and interior vane, on the outer wall of described outer vane, uniform ring is around some blast pipes, exogenous wind chamber is formed, wind chamber in being formed between described wind bowl and described interior vane between described outer vane and described wind bowl; Wherein, described wind bowl evenly offers some outer air holes, the outer wall of described interior vane evenly offers some interior air holes, between described wind bowl and described interior vane, wind lip is installed.
In a preferred embodiment of the present invention, described outer air holes is outer little interior large bellmouth.
In a preferred embodiment of the present invention, described interior air holes is the little reverse taper hole of outer imperial palace.
In a preferred embodiment of the present invention, described wind lip presents thin lower thick structure, and top tilts upward.
In a preferred embodiment of the present invention, the quantity of described blast pipe is more than or equal to 6.
In a preferred embodiment of the present invention, the blowing vane structure of described plastic sheeting also comprises the exhaust duct be connected with described interior vane.
The invention has the beneficial effects as follows: by adopting inside and outside vane structure, and air holes inside and outside special construction is evenly offered on interior vane and wind bowl, make air-out even, the film thickness of blowout is even, thus improve cooling effect, reduce energy consumption, add film clarity, improve product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation in blowing vane structure one preferred embodiment of a kind of plastic sheeting of the present invention;
In accompanying drawing, each mark is as follows: 1, outer vane, and 2, wind bowl, 21, outer air holes, 3, interior vane, 31, interior air holes, 4, blast pipe, 5, exhaust duct, 6, exogenous wind chamber, 7, interior wind chamber, 8, wind lip.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of blowing vane structure of plastic sheeting, comprise: outer vane 1, wind bowl 2 and interior vane 3, on the outer wall of described outer vane 1, uniform ring is around some blast pipes 4, forms exogenous wind chamber 6 between described outer vane 1 and described wind bowl 2, wind chamber 7 in being formed between described wind bowl 2 and described interior vane 3; Wherein, described wind bowl 2 evenly offers some outer air holes 21, the outer wall of described interior vane 3 evenly offers some interior air holes 31, between described wind bowl 2 and described interior vane 3, wind lip 8 is installed.
Described outer air holes 21 is in outer little interior large bellmouth, and tapering is 1:3, and make uniform stream, stablize, air-out is even, and improves cooling effectiveness.
The reverse taper hole that described interior air holes 31 is little in outer imperial palace, tapering is 3:1, and make uniform stream, stablize, air-out is even, and improves cooling effectiveness.
Cooling air blows to film bubble by outer air holes 21 and interior air holes 31, improves cooling effectiveness, and enhances film clarity.
Described wind lip 8 presents thin lower thick structure, and top tilts upward, and gradient is 1:2, plays the effect reducing energy consumption.
The quantity of described blast pipe 4 is more than or equal to 6.
The blowing vane structure of described plastic sheeting also comprises the exhaust duct 5 be connected with described interior vane 3, for discharging the hot blast in film bubble, making film bubble internal temperature keep stable, improving cooling effect, and makes that film thickness is even, transparency good.
Present invention is disclosed a kind of blowing vane structure of plastic sheeting, by adopting inside and outside vane structure, and air holes inside and outside special construction is evenly offered on interior vane and wind bowl, make air-out even, the film thickness of blowout is even, thus improves cooling effect, reduces energy consumption, add film clarity, improve product quality.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and Figure of description content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
