Abstract
The utility model relates to a duckbilled air nozzle for BOPET (polyester film) casting sheet edge blowing. The duckbilled air nozzle for BOPET casting sheet edge blowing comprises a nozzle body, wherein a through hole for feeding air is arranged inside the nozzle body; and the upper part of the nozzle body is of a shape of a cylinder, and an outer thread connected with a pipeline is arranged at the upper end part of the nozzle body. The duckbilled air nozzle is characterized in that the lower part of the nozzle body is flat (duckbilled), and the mouth of the nozzle body is a rectangular opening. The duckbilled air nozzle disclosed by the utility model is good in a blank pressing effect.
Description
Technical field
The utility model relates to a kind of BOPET of being used for casting sheet and blows the air nozzle on limit.
Background technology
Existingly a kind ofly be used to prevent that the casting sheet of sharp cooling roll limit portion fouling when BOPET produces from blowing the limit treatment facility; It comprises first air nozzle, second air nozzle, pipeline, air compressor; First air nozzle, second air nozzle are connected with the compressed air output of air compressor by pipeline respectively; First air nozzle, second air nozzle are positioned between the outlet and sharp cooling roll of die head (die head of BOPET production line); The mouth mouth (nozzle) of first air nozzle, second air nozzle is respectively over against the static silk that is used for die casting sheet limit, and first air nozzle is positioned at the right of casting sheet (BOPET casts sheet), and second air nozzle is positioned at the left side of casting sheet; The nozzle of flanging air nozzle is circular, the flanging weak effect.
Summary of the invention
The purpose of the utility model is to provide the effective Duckbill type BOPET casting sheet of a kind of flanging to blow the limit air nozzle.
To achieve these goals; The technical scheme that the utility model is taked is: Duckbill type BOPET casting sheet blows the limit air nozzle; It comprises sprayer body; For being used for the through hole of blowing air, the top of sprayer body is cylindrical shape in the sprayer body, and the upper end of sprayer body is provided with and is used for the external screw thread that links to each other with pipeline; It is characterized in that: the bottom of sprayer body is offset flat shape (Duckbill type), and the mouth mouth of sprayer body is a rectangle hole.
The beneficial effect of the utility model is: the mouth mouth of air nozzle adopts rectangle hole, and flanging is effective.
