Description
Technical field
The utility model relates to film blowing device field more particularly to a kind of cooling vanes of inflation film.
Background technique
Plastic film blowing machine mostly uses upper blowing method to be produced, and is equipped with cooling air ring, each cooling wind in head upper
It is equipped with annular passage in ring, the air outlet of multiple opening directions upward is typically provided on the inside of annular passage.In production process
In, plastics melt flows out from head and is formed film bubble, and film bubble is constantly moved upwards by traction, and is located at the cooling wind of film bubble periphery
Ring then constantly blows out upward high-speed flow, and high-speed flow plays the effects of cooling and stable film bubble, meanwhile, cooling air ring
High-speed flow can also air around traction, formed so-called " underbalance effect ", to facilitate the inflation of film bubble.
It is well known that the cooling effect of cooling air ring has a significant effect for the quality of production and speed of production of film,
The cooling velocity of cooling air ring directly limits the speed of production of film.In order to improve cooling velocity, currently used mode is
Increase intake, but after intake increase, cold wind, which forms film bubble, to be impacted, and outlet air wind pressure is high, and energy consumption is big, cooling effect
Difference, uneven film thickness is even, and film clarity is poor, and bubble stability is poor.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of cooling vanes of inflation film, in the stream for being passed through wind
In the case that speed is constant, film-cooled heat is increased, keeps the wind for blowing to film bubble softer, under the premise of guaranteeing cooling effect,
Keep film bubble more stable.
The utility model is achieved by the following technical solution, and provides a kind of cooling vane of inflation film, including circle
Cylinder, and it is fixed in the upper ring plate and lower ring plate of cylinder inner wall, the inward flange of the upper ring plate is connected with the inner cylinder extended downwardly,
The inner wall of inner cylinder has been connected through a screw thread lip, and the inward flange of the lip is equipped with the inclined-plane upwardly extended, and inclined-plane upper end is outside
Inclination is installed with the sieve pendulum aerofoil being circumferentially closed between the lower end and lower ring plate of inner cylinder；The diameter of bore of lower ring plate is less than
Upper ring plate diameter of bore, and the wind blocking cylinder upwardly extended is connected in the inner port edge of lower ring plate, cylinder, upper ring plate, lower ring plate,
Inner cylinder and sieve pendulum aerofoil form the wind chamber circumferentially penetrated through, offer the air inlet being connected to wind chamber on lower ring plate.
When in use, cooling wind is from air inlet into air-inlet chamber, then through shape between lip and lower ring plate for the vane of this programme
At air intake passage, flowed out, and be blown to film bubble outer surface and cooled down, passed through by the air outlet that is formed between lip and wind blocking cylinder
Air duct is formed between the inclined-plane and film bubble of setting, cooling wind is guided, extends the heat-exchange time of cooling wind and film bubble, is improved
Cooling efficiency；Aerofoil is put by setting sieve, so that it is more uniform by the cooling wind of sieve pendulum aerofoil, and put using sieve
Aerofoil is filtered the solid particle in air-flow, prevents film bubble from being scratched；By the way that wind blocking cylinder is arranged, avoid cooling wind to film bubble
Vertical impact is carried out, the stability of film bubble is improved, keeps bubble thickness more uniform consistent；Lip is connected by screw thread and inner cylinder
It connects, realizes the adjustment of lip position, be adjusted so as to the size to air intake passage, be passed through wind speed inconvenience in air inlet
In the case where, the wind speed of air outlet is adjusted, the cooling requirement of different-thickness film bubble is met.
As optimization, the horizontal distance between the lower edge and wind blocking cylinder on the inclined-plane is 75 ~ 150mm.This prioritization scheme
Horizontal distance setting between the lower edge and wind blocking cylinder on middle inclined-plane, at least increases 50% compared with the outlet of the vane of the prior art,
In the case where the flow velocity for being passed through wind is constant, keep the wind for blowing to film bubble softer, in the case that linear velocity improves 10%, thickness
The uniformity improves 70%, and breadth can be improved 20%, and film bubble is more stable.
As optimization, the length on the inclined-plane is 150 ~ 200mm.Chamfer length is set as 150 ~ 200mm by this prioritization scheme,
Enough guidance distances are provided to the guiding of cooling wind, reduce the diffusion of cooling wind, flow cooling wind along film bubble outer wall,
Improve inflation effect.
As optimization, the thickness of the lip is not less than inner cylinder and the 2/3 of lower ring plate spacing.This prioritization scheme lip thickness
Setting, the adjusting range of air intake passage sectional area is improved, to increase the use scope of this vane.
As optimization, the air inlet has been connected through a screw thread double pin ends.This prioritization scheme is by being arranged double public access
Head is facilitated and is attached with blower and pipeline, and easy to operate.
The utility model has the following beneficial effects: making to be blown to the cold of film bubble outer surface in the case where being passed through distinguished and admirable fast fixed
But wind is softer, uniform, and under the premise of guaranteeing cooling effect, the thickness uniformity of film bubble can be improved 70%, and breadth can be improved
20%, and film bubble is more stable, due to the main intake of relative reduction, also saves the energy consumption of blower.
