Abstract
A cooling air ring for film blowing machines comprises an air ring body, which has a ring air duct. Inside the air duct is the first outlet opening up diagonally; below the first outlet is the second outlet opening down diagonally; between the first outlet and second outlet is the third outlet opening to the horizontal direction; the width of the third outlet is less than that of the second outlet and the first outlet; the size of the first outlet and second outlet is adjustable, wherein the high-speed airflow blown out of the second outlet forms the opposite movement of the bubble, due to the airflow's downward direction, resulting in the increase of relative velocity of airflow and the bubble, thus increasing the cooling rate of the bubble, improving the quality and quantity of the bubble, and blowing the bubble in advance, without affecting the stability of the bubble running.
Description
Technical field
The utility model belongs to the plastic membrane blowing apparatus technology, is specifically related to a kind of inflation film manufacturing machine cooling vane.
Background technology
Plastic film blowing machine mostly adopts upper blowing method production, and is provided with cooling vane at head upper, and each cooling vane is provided with annular passage, generally is provided with two opening directions air outlet up in the annular passage inboard.In process of production, plastics melt flows out and forms film from head and steeps, the film bubble is pulled constantly and moves upward, be positioned at the peripheral cooling vane of film bubble and then constantly blow out high velocity air upwards, to cooling and effect such as stable, simultaneously, the high velocity air of cooling vane also can the traction ambient air to the film puff for high velocity air, form so-called " underbalance effect ", thereby help the inflation of film bubble.
As everyone knows, the cooling effect of cooling vane all has a significant effect for the quality of production and the speed of production of film, and the cooling velocity of cooling vane has directly limited the speed of production of film.Therefore in the prior art, in order to improve the speed of production of film, must take to improve the mode of air velocity, improve the cooling effectiveness of film with hope, but wind speed is excessive, and meaning requires the blast of cooling vane inside high more, and blast get over Gao Zeyue be unfavorable for air-flow evenly, stable, and then make film bubble fluctuation of service easily, influenced the blowfilm shaping quality.
In addition, in the prior art, film bubble only just begins behind the certain distance above the cooling vane owing to " underbalance effect " and inflation having run to; Therefore, owing to must reach the inflation ratio of setting within a short period of time, the inflation process is more rapid, and the inflation quality also can be affected.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of inflation film manufacturing machine cooling vane is provided, and it can improve film bubble cooling velocity and don't influence film bubble operation stability.
Its purpose can realize by following scheme: this inflation film manufacturing machine cooling vane comprises the vane body, the vane body is provided with annular passage, the annular passage inboard is provided with opening first air outlet obliquely, and its main feature is, also is being provided with second air outlet of opening under oblique below first air outlet.
Be preferably, between first air outlet and second air outlet, also be provided with three air outlet of opening towards horizontal direction; The A/F of the 3rd air outlet is less than the A/F of second air outlet, first air outlet.
Be more preferably the adjustable size of first air outlet and second air outlet.
The utlity model has following advantage and effect:
1, the utility model is in the blown film process, plastics melt flows out and forms film from head and steeps, film bubble is pulled constantly and moves upward, and first air outlet of cooling vane constantly blows out high velocity air obliquely, and second air outlet of cooling vane constantly blows out the high velocity air under oblique.Wherein, effect, effect and the traditional structure of the high velocity air that blows out of first air outlet are basic identical; And the high velocity air that second air outlet blows out, because direction down, therefore form the opposite motion of direction with the film bubble, thereby having improved air-flow (compares with traditional structure with the speed of related movement of film bubble, relative velocity improves the twice that numerical values recited is the film bubble speed of service), therefore can improve cooling velocity, improve the quality and the output of film bubble the film bubble.On the other hand, though the speed of related movement of air-flow and film bubble improves, the air-flow self speed does not improve, and the blast of vane inside need not to improve, and therefore can not have influence on film bubble operation stability.
2, the oblique down high velocity air that blows out of second air outlet, can below cooling vane, form underbalance effect, below cooling vane, just begin tentatively to obtain inflation after making the film bubble leave head, compare with traditional structure, the film bubble will be shifted to an earlier date inflation, be equivalent to machine head port mould and amplify, and the film-cooled heat of film bubble is strengthened, help improving film bubble cooling effect, improve output.
3, the A/F of the 3rd air outlet is little, can blow out the horizontal direction air-flow of trace, its effect is: the high velocity air that first air outlet blows out upwards, the vane ambient air upwards can be carried, and the high velocity air that second air outlet blows out is downward, the vane ambient air can be carried downwards, therefore apparent in view in negative pressure near the neighboring area of vane; For this reason, the air-flow that the 3rd air outlet can blow out trace replenishes, and avoids too high near the neighboring area negative pressure degree of vane.

The specific embodiment
Fig. 1, Fig. 2, inflation film manufacturing machine cooling vane shown in Figure 3 are installed in above the head 2, and the distance of cooling vane and head can be regulated by lifting regulating mechanism 15.This cooling vane comprises vane body 1, and vane body 1 is provided with annular passage 14, is provided with shunting disk 16 in the middle of the annular passage 14, and the inboard is provided with opening first air outlet 11 obliquely, also is being provided with second air outlet 12 of opening under oblique below first air outlet; Between first air outlet and second air outlet, also be provided with three air outlet 13 of opening towards horizontal direction; Wherein, the big I of first air outlet 11 and second air outlet 12 is regulated by handle according to the technology of producing, and the A/F of the 3rd air outlet is less than the A/F of second air outlet, first air outlet.
Fig. 1, shown in Figure 2 when the foregoing description is installed, is raised to the inflation film manufacturing machine cooling vane apart from the head certain altitude, and the distance of vane and head can be regulated by lifting regulating mechanism 15, to adapt to different blow-up ratios.During the foregoing description work, plastics melt flows out and forms the film bubble 3 of the operation that constantly makes progress from head 2, first air outlet 11 of cooling vane constantly blows out high velocity air obliquely, second air outlet 12 of cooling vane constantly blows out the high velocity air under oblique, and the 3rd air outlet 13 can blow out the horizontal direction air-flow of trace.After the micro-air-flow that the 3rd air outlet blows out blows out, also can be carried and move upward by the high velocity air that first air outlet blows out.
