Abstract
The invention discloses a film blowing machine use ventilation plugboard, the plugboard is provided with a ventilation pipe, and the ventilation pipe is provided with at least one air outlet. The film blowing machine use ventilation plugboard is characterized in that: the film blowing machine use ventilation plugboard is simple in structure, through the installation of the ventilation pipe, an air interlayer can be formed between a film and the ventilation pipe at the folding and bending position of the film, film resistance of the plugboard can be reduced, friction can be reduced, cooling of the folding and bending position of the film can be increased, the appearance quality of the film can be greatly improved.
Description
Technical field
The present invention relates to plastic membrane blowing field, be specifically related to inflation film manufacturing machine ventilation plate.
Background technology
The large-scale plastic inflation film manufacturing machine of four tunics that is equipped with collapser and plate, due to its structural requirement, plate volume is large, and length is long, and plate increases greatly to drag of film, causes film surface temperature high, and fold is many, reduces film appearance quality.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of inflation film manufacturing machine ventilation plate is provided.
The technical scheme that the present invention adopted is for achieving the above object: inflation film manufacturing machine ventilation plate, ventilation duct is installed on plate, and on described ventilation duct, offer at least one air outlet.
Described ventilation duct is arranged on the both sides in plate front.
Described ventilation duct length is identical with plate side edge length.
Described air outlet external diameter is greater than internal diameter.
Feature of the present invention is: simple in structure, by ventilation duct is installed, in the folding corner of film, between film and ventilation duct, form air buffer, lower plate to drag of film, reduce frictional force, increase the cooling of film corner, greatly improved film appearance quality.
Brief description of the drawings
Fig. 1 is the conventional board plug structure figure of large-scale inflation film manufacturing machine;
Fig. 2 is structure chart of the present invention;
Fig. 3 is ventilation duct structure chart;
Fig. 4 is air outlet cross sectional representation.
Wherein: 1, plate 2, Upper adjusting device 3, lower regulating mechanism 4, ventilation duct 5, air outlet E, plate front.
Detailed description of the invention
As Figure 1-4, the present invention is inflation film manufacturing machine ventilation plate, Upper adjusting device and lower regulating mechanism are installed on plate 1, on the both sides of plate 1 positive E, ventilation duct 4 is installed, described ventilation duct 4 length are identical with plate 1 side edge length, on described ventilation duct, offer several equidistant air outlets 5 from top to bottom, the external diameter of described air outlet 5 is greater than internal diameter.
When work, inflation film manufacturing machine film is under collapser effect, the film-folding of drum is built up to two membranes, (plate 1 first inserts after the film of drum to become four-level membrane through the effect of plate 1 again, folding through collapser again), plate 1 inserts cylindrical thin-film and folds, the folding corner of film produces larger friction, film surface is produced and scratched, also produce a large amount of frictional heats, by ventilation duct 4 being installed in the both sides of the positive E of plate, in the folding corner of film, by air outlet 5, between film and ventilation duct 4, form air buffer, reduce frictional force, increase the cooling of film corner, greatly improve film appearance quality.
The above; it is only preferably detailed description of the invention of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
