Growing along with packaging industry, increasing to the use amount of film, require more and more faster to the speed of production of cast film machine, and the High Rotation Speed of casting roller must drive ambient air and then to rotate, casting roller surface is made to produce an airflow layer, this just makes to produce bubble between casting roller and non-form film, cause film out-of-flatness and inhomogeneous cooling even, the even thickness uniformity and the transparency affecting film of inhomogeneous cooling.
Utility model content
For the problem of above-mentioned cast film machine, the utility model provides a kind of double-layer vacuum pumping device removing chill roll airflow on surface layer, thus stationary flow extends the film come, and improves film quality.
Technical solutions of the utility model are as follows:
A kind of cast film machine casting roller vacuum extractor, comprise centrifugal blower, connecting hose and vacuum tank, described centrifugal blower comprises centrifugal blower first inlet scoop and centrifugal blower second inlet scoop, described vacuum tank comprises vacuum tank first chamber and vacuum tank second chamber, and described vacuum tank first chamber and vacuum tank second chamber are connected with centrifugal blower first inlet scoop and centrifugal blower second inlet scoop respectively by one group of connecting hose; Equally distributed inlet scoop can ensure the air pressure uniformity in vacuum tank second chamber and vacuum tank first chamber, vacuum tank first chamber not only can remove the airflow layer on casting roller surface, also can clean casting roller surface, vacuum tank second chamber Main Function removes the air between casting roller and cast film, cast film is made to be close to casting roller surface, thus reach the effect of locating and extending the film come with stationary flow, improve flatness and the cooling effect of film further.
Further, the upper and lower both sides of described vacuum tank first chamber are respectively arranged with chute, vacuum tank dividing plate is separately installed with in described chute, the upper end of described vacuum tank dividing plate is connected with the lower end of an adjusting screw(rod), the top of adjusting screw(rod) is connected to the bottom of vacuum tank, is arranged with a spring outside adjusting screw(rod).Described spring be for prevent casting roller due to descending operation improper and vacuum tank is damaged by pressure, described adjusting screw(rod) can gap between vacuum tank dividing plate and casting roller described in manual adjustments.
Further, at vacuum tank first chamber and vacuum tank second chamber both sides, vacuum tank side adjustable plate is also installed.
Further, described vacuum tank first cavity bottom is provided with an orifice plate, and described orifice plate is provided with multiple hole.
Further, the airflow regulating switch regulating vacuum tank second chamber air draught size is also had in described centrifugal blower second chamber.
The beneficial effects of the utility model: by designing the two-chamber of casting roller vacuum extractor, improve the flatness of film, decreasing casting films necking down, reducing the width of cutting slitter edge, thus reaching the effect of energy-conserving and environment-protective; Meanwhile, substantially increase the speed of production of cast film machine, improve production efficiency.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, be described further technical solutions of the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
See Fig. 1-Fig. 3, a kind of cast film machine casting roller vacuum extractor, comprise centrifugal blower 4, connecting hose 8 and vacuum tank 9, described centrifugal blower 4 comprises centrifugal blower first inlet scoop 5 and centrifugal blower second inlet scoop 6, described vacuum tank 9 comprises vacuum tank first chamber 15 and vacuum tank second chamber 16, and described vacuum tank first chamber 15 and vacuum tank second chamber 16 are connected with centrifugal blower first inlet scoop 5 and centrifugal blower second inlet scoop 6 respectively by one group of connecting hose; Equally distributed inlet scoop can ensure the air pressure uniformity in vacuum tank second chamber 16 and vacuum tank first chamber 15.
Particularly, casting roller vacuumizes case and is fixedly installed on casting head 2 by pair of right and left vacuum tank fixed connecting piece 3; Also be provided with vacuum tank side adjustable plate 10 at vacuum tank first chamber 15 and vacuum tank second chamber 16 both sides, vacuum tank fixed connecting piece 3 is positioned at above vacuum tank side adjustable plate 10; Described vacuum tank first chamber about 15 both sides are respectively arranged with chute 17, vacuum tank dividing plate 13 is separately installed with in described chute 17, the upper end of described vacuum tank dividing plate 13 is connected with the lower end of an adjusting screw(rod) 11, the top of adjusting screw(rod) 11 is connected to the bottom of vacuum tank 9, is arranged with a Compress Spring 12 outside described adjusting screw(rod) 11; Vacuum tank dividing plate 13 can carry out manual adjustments by adjusting screw(rod) 11 with the gap of casting roller 1, described Compress Spring 12 be for prevent casting roller due to descending operation improper and vacuum tank is damaged by pressure, described adjusting screw(rod) 11 can gap between vacuum tank dividing plate 13 and casting roller 1 described in manual adjustments.
Particularly, one piece of orifice plate 14 is installed bottom vacuum tank first chamber 15, orifice plate is provided with multiple hole, can air pressure further between uniform vacuum case first chamber 15 and casting roller 1, vacuum tank second chamber 16 and the casting roller air pressure between this goes back to gap by the labyrinth type song designed in vacuum tank second chamber and obtains further evenly.
Particularly, the airflow regulating switch 7 regulating vacuum tank second chamber air draught size is also had in described centrifugal blower second chamber 16.
Be described further prolonging roller vacuum extractor operation principle below, vacuum tank first chamber 15 and vacuum tank second chamber 16 are due to the effect of the vacuum tank dividing plate 13 that is provided with and vacuum tank side adjustable plate 10, when centrifugal blower works, vacuum tank 9 is made well to reach vacuum state, vacuum tank first chamber 15 not only can remove the airflow layer on casting roller 1 surface, casting roller 1 surface can be cleaned simultaneously, vacuum tank second chamber 16 Main Function removes the air between casting roller 1 and cast film, cast film is made to be close to casting roller 1 surface, thus reach the effect of locating and extending the film come with stationary flow, the flatness of further raising film and cooling effect, namely the cooling effect raising of film makes the transparency of film improve.The size of vacuum tank second chamber 16 air draught can be regulated by the airflow regulating switch 7 be arranged in centrifugal blower second chamber 6.Because surperficial for casting roller 1 most of air siphons away by vacuum tank first chamber 15, so the very little a part of suction of vacuum tank second chamber 16 need can remove the air between casting roller 1 and casting films, excessive suction can by the firm film modification extruded from casting head, so this kind of two-chamber vacuum extractor can remove the airflow layer on casting roller surface completely, film modification can not be caused because of excessive suction simultaneously.
The beneficial effects of the utility model: by designing the two-chamber of casting roller vacuum extractor, improve the flatness of film, decreasing casting films necking down, reducing the width of cutting slitter edge, thus reaching the effect of energy-conserving and environment-protective; Meanwhile, substantially increase the speed of production of cast film machine, improve production efficiency.
Be more than better embodiment of the present utility model, but embodiment is not for limiting the utility model.Not departing from the spirit and scope of the utility model, any equivalence change done or retouching, belong to the protection domain of the utility model equally.Therefore the content that protection domain of the present utility model should define with the claim of the application is standard.
