Abstract
A kind of film blowing machine head air ring cooling device, relates to inflation film manufacturing machine field；For the problem that existing film blowing machine head vane is excellent not on cooling effect, this utility model is based on below scheme: a kind of film blowing machine head air ring cooling device, including lower vane, fan housing and upper vane；Lower vane upper end is connected with bottom fan housing, is connected with fan housing upper end bottom upper vane, and fan housing is cylindrical tube shape；Described leeward hoop up-draught is blown into fan housing, and under windward hoop, blowing enters fan housing, arranges air outlet in the middle part of fan housing；Based on above structure, it is possible to optimizing the flow regime of cooling air, cooling effect is more preferably.
Description
Technical field
This utility model belongs to inflation film manufacturing machine field, is specifically related to a kind of film blowing machine head air ring cooling device.
Background technology
Inflation film manufacturing machine be by plastic pellet heating and melting again blow out thin film, mainly by extruder, head, die head, chiller,
Surely steep the compositions such as frame, collapser, carry-over pinch rolls, devices for taking-up.In using air-cooled inflation film manufacturing machine, chiller refers mainly to vane；
Squeezing in blow moulding flat, the air of traditional vane flows from the bottom to top, and its technique, apparatus structure are simple, but its cooling sky
Air-flow body is not in good state, and is not parastate with film；Meanwhile, unidirectional flowing is not likely to produce turbulent flow, and cooling effect is the most excellent
Different.
Utility model content
Technical problem to be solved in the utility model is: the cooling air fluid for existing inflation film manufacturing machine vane flows
It is not in good state, the problem that cooling effect is excellent not, this utility model provides a kind of Novel film blowing machine head air ring cooling device,
Can preferably solve problem above.
Technical solution adopted in the utility model is: a kind of film blowing machine head air ring cooling device, including lower vane, wind
Cover and upper vane；Lower vane upper end is connected with bottom fan housing, is connected with fan housing upper end bottom upper vane, and fan housing is cylindrical tube shape；
Described leeward hoop up-draught is blown into fan housing, and under windward hoop, blowing enters fan housing, arranges air outlet in the middle part of fan housing.
Further, it is symmetrical arranged at least 2 air outlets in the middle part of described fan housing.
The beneficial effects of the utility model are: increase fan housing and the volume being connected with the fan housing other end on existing vane
Outer vane, in film extrusion process, the vane at fan housing two ends is all dried in fan housing, and air is discharged from the air outlet of fan housing；
On the one hand, two strands of reverse cooling cross-ventilations, it is possible to produce complicated fluid kinestate, be conducive to breaking detention layer, profit
In heat radiation；Additionally under identical cooling air velocity, cooling air delivery of the present utility model is 2 times of traditional vane,
More heat can be taken away；Finally, the fan housing body of fan housing, it is possible to change the flow direction of cooling air, be allowed to and thin film table
Face PARALLEL FLOW, is beneficial to heat radiation.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of described a kind of film blowing machine head chiller；
Fig. 2 is the upper and lower vane top view of described a kind of film blowing machine head chiller；
Fig. 3 is Section A-A sectional view in Fig. 2；
In figure, vane under 1-, 2-fan housing, the upper vane of 3-, vane ring body under 11-, vane air inlet under 12-, vane under 13-
Air outlet, 21-cover body, 22-air outlet, 31-upper vane ring body, 32-upper vane air outlet, 33-upper vane air outlet.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
A kind of film blowing machine head chiller as shown in Figure 1, Figure 2, Figure 3 shows, including lower vane 1, fan housing 2 and upper vane 3；
Lower vane 1 includes lower vane ring body 11, lower vane air inlet 12 and lower vane air outlet 13, is provided with centered by lower vane ring body 11
The cylinder in air channel, is symmetrical arranged at least 3 lower vane air inlets 12, the lower vane air inlet number that embodiment shown in figure is arranged
Amount is 4.Upper vane 3 structure is similar with lower vane 1 structure, simply there are differences owing to being actually needed in specification.
Lower vane 1 upper end is connected bottom fan housing 2, is connected with fan housing 2 upper end bottom upper vane 3, and fan housing is cylindrical tube shape；
Described lower vane 1 upwards blowing enters fan housing 2, and the upper downward blowing of vane 3 enters fan housing 2, arranges air outlet 22 in the middle part of fan housing 2.
It is symmetrical arranged at least 2 air outlets in the middle part of described fan housing 2.
Existing vane increases fan housing 2 and the extra vane being connected with the fan housing other end, at film extrusion process
In, the vane at fan housing 2 two ends is all dried in fan housing, and air is discharged from the air outlet of fan housing 2；On the one hand, two strands reverse cold
But cross-ventilation, it is possible to produce complicated fluid kinestate, be conducive to breaking detention layer, is beneficial to heat radiation；Additionally identical
Under cooling air velocity, cooling air delivery of the present utility model is 2 times of traditional vane, it is possible to take away more heat；
Finally, the cover body 21 of fan housing 2, it is possible to change the flow direction of cooling air, be allowed to and film surface PARALLEL FLOW, is beneficial to dissipate
Heat.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.This reality
Being not restricted to the described embodiments with novel, simply illustrating described in above-described embodiment and description is of the present utility model former
Reason, on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these become
Change and improve and both fall within the range of claimed this utility model.This utility model claims scope by appended right
Claim and equivalent thereof define.
