The first counter bore 6 and the second counter bore 8 are penetrated through by bolts, so that the inner die 2 and the outer die 1 are conveniently and coaxially fixed in the wind ring. The material is blown out from a discharge chute 4 between the inner die 2 and the outer die 1 through wind, so that the film blowing processing operation is completed. Wherein because be equipped with on the top of centre form 2 and prevent stifled groove 5, prevent stifled groove 5 and increase the export size of blown down tank 4 to when the material blew off from blown down tank 4, difficult adhesion blockked up blown down tank 4 on the cell wall, reduced the possibility that blown down tank 4 blockked up, thereby maintained film production, improved film production efficiency.
Example two:
the difference between the second embodiment and the first embodiment is the cross-sectional shape of the anti-blocking groove 5.
Referring to fig. 3, the section of the anti-blocking groove 5 is in a right trapezoid shape, and two right-angle sides of the section of the anti-blocking groove 5 are respectively located on the upper side of the inner mold 2 and the peripheral side of the inner mold 2. The section is the size that prevents that stifled groove 5 of right trapezoid set up has conveniently increased the export of blown down tank 4 to the blown down tank 4 is difficult for being plugged up to the material. Meanwhile, the anti-blocking groove 5 with the right trapezoid cross section reserves the shrinkage for the formed film, and the possibility of shrinkage and tearing of the film after leaving the discharge groove 4 is reduced.
Example three:
the third embodiment is different from the first and second embodiments in that the shape of the cross section of the anti-clogging groove 5 is different.
Referring to fig. 4, the anti-clogging groove 5 is provided in an arcuate shape in cross section. The size of the outlet of the discharge chute 4 is conveniently increased by the anti-blocking groove 5 with the arc-shaped cross section, so that the discharge chute 4 is not easily blocked by materials. Meanwhile, the anti-blocking groove 5 with the arched section reserves the shrinkage for the formed film, and the possibility of shrinkage and tearing of the film after leaving the discharge groove 4 is reduced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
