Claim.
Compared with prior art, the method have the advantages that
1, the plenum chamber of the present invention passes through aerodynamic principle appropriate design, owing to plenum chamber adds centre
Dividing plate, inherently can make the blower fan air to blowing in two ends change wind direction and in this bulk container of plenum chamber
Make under cushioning effect air reach pressure equilibrium effect.
2, the multiple warm areas during the present invention is arranged on transverse stretching machine, the stretched film of each warm area be respectively arranged with up and down 4 quiet
Pressure case, is divided into left and right sides, i.e. the most each 2 plenum chambers in left side form one group, will by blower fan A and blower fan B
After the air of air heater heating sucks from plenum chamber two ends in the middle of plenum chamber to blowing, 4, right side
Plenum chamber by blower fan C and blower fan D will the air that heat through air heater suck after from plenum chamber two ends to
To blowing in the middle of plenum chamber, enter plenum chamber add hot gas be sufficiently mixed by plenum chamber, pressure uniform after,
From the air outlet of plenum chamber, all uniform hot-air of spouting velocity and pressure, forms uniform temperature field, pressure
The field of force, makes stretched film homogeneous deformation, improves thickness evenness and the microcosmic inherent quality of stretched film.Air
Heater is positioned at stretched film region below, can be sucked by the cold air of lower rapidly and heat, it is ensured that static pressure
In case, air themperature field is relatively uniform and stable, plays crucial work for improving stretched film Mass lost rupture of membranes rate
With.
