Description
Technical field
What the utility model related to a kind of film unreels expanding unit, and for the manufacture of thin-film unreeling and the overlay film of single-oriented presoaked cloth, particularly several micron is to the parallel expansion film covering device of the polyethylene film easy wide cut ultrathin membrane of tens microns.
Background technology
The production requirement of prepreg cloth is sprawled parallel for filament fiber, micron-sized for diameter fiber is required evenly to spread out, gluing, overlay film, the direction of all fibres is all that radial direction does not have broadwise, therefore claim without latitude cloth, superhigh molecular weight polyethylene fibers is without latitude cloth, carbon fiber prepregs and Aramid No-Woven Cloth etc. need to cover the very thin elastic membrane of one deck aborning, because required film is very thin, generally only has several micron to tens microns, pulling strengrth and modulus are all very low, the tensile force that can bear is very low, using traditional glue strip type crimp roll etc. to need film to bear comparatively hightension drives the rotation of adhesive tape crimp roll just can play spreading, and only have tension-thining will narrowing plastic deformation even occurs under tension of micron level thickness, product design is caused to be had a strong impact on, patent publication No. is CN2871589 in addition, CN201221020, CN2366430, CN1066791C, a Japanese Patent CN1066791C etc. is also had all to mention spreading roll or be worm felt roll, all make use of symmetrical helicitic texture, fabric open-width is realized by driven by motor active rotation, expanding effect, but mechanism is more complicated, require belt strap some tension, for ultrathin membrane, tension force is inapplicable too greatly, in addition because being limited on continuous prepreg cloth manufacturing line of space is also difficult to repacking, patent publication No. is that the relatively aforementioned several mode structure of CN201525938 is relatively simple, tensioned controller realizes tension force and controls, also be utilize thread roller to open up film as worm felt roll, film through 4 motor-driven worm felt rolls of unified driving and 1 overlay film roller with without latitude cloth compound, drive motor overcomes by film the tension force that tension control assembly gives and drives film volume to rotate, carry out along with unreeling, the more and more less gravity of diameter of film roll is also more and more less, causes tension fluctuation.
The principle of thread roller stent utilizes film to be recessed into inside screw thread, and after electric machine rotation worm felt roll, the film inside recessed screw thread is subject to lateral compression and abduction, requires that the screw thread side smoothness of roller is high, otherwise scratch even tear because pair of films is made in friction.
Separately have expander series of patents as:
CN201120042472, the multiple expander of power driven;
CN200830236751, spoke type;
CN200820038705, corrosion-resistant steel spoke type;
CN200530171811, glue strip type;
CN02220729, there is the expander of concavo-convex increase skin friction force on surface;
CN99228747, metal spoke;
Utilize spoke and eccentric center principle, by spoke around axis rotation time axial two ends stretch and drive fabric to launch, the fold of fabric is eliminated, this mode is effective and stable in the expansion of fabric, this wherein has two basic premises, and one is that fabric can bear comparatively hightension, and two is have larger friction coefficient between fabric and spoke, so can drive fabric open-width or expansion when spoke abduction, dispel fold.And for ultrathin membrane, these two prerequisites all cannot stable existence, because ultrathin membrane film thickness is limited, to can bear tension force lower, along with the prolongation of period of service, the friction coefficient of film and spoke can be more and more lower, expander even cannot be driven to rotate to the later stage, therefore the expander of spoke type also cannot realize stable and parallel expansion.
