Abstract
The utility model discloses a casting production line of a polypropylene thin membrane. The casting production line comprises an extrusion machine, a sudden cooling shaping device, a thickness measuring device, a corona device, a traction device, a trimming device and a winding device which are arranged along the conveying direction of the thin membrane in sequence. The casting production line is characterized by further comprising a hot roller and an oxygen supply device for supplying oxygen for the corona device, wherein the hot roller is arranged between the sudden cooling shaping device and the thickness measuring device and is capable of providing certain energy for the thin membrane, so that a secondary crystallization behavior of the thin membrane can rapidly occur on the production line but not after the thin membrane is wound and delivered, the possibility of crease during maturation after the product is delivered is avoided, meanwhile, the maturation period is shortened and the splitting operation can be performed in a short time; through the improvement, an original needed maturation period is greatly shortened from 24-48 h to 20h.
Description
Technical field
The utility model relates to a kind of polypropylene film curtain coating production line.
Background technology
Known, polypropylene film curtain coating production line, mainly comprise the extruder of arranging successively along film throughput direction, quenching shaping equipment, calibrator, corona unit, draw-gear, trimming device and wrap-up, because the characteristic of polypropylene film has secondary crystallization behavior, secondary crystallization behavior occurs after rolling is rolled off the production line, therefore, polypropylene film after rolling off the production line need to carry out slaking, this process had both easily caused product wrinkle, need again to extend cure cycle and could eliminate the internal stress that secondary crystallization produces, conventionally need 24-48 hour hardening time, this overlong time, easily affect due date.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of polypropylene film curtain coating production line that shortens hardening time, enhance productivity is provided.
The purpose of this utility model realizes by following technical solution:
A kind of polypropylene film curtain coating production line, comprise extruder, quenching shaping equipment, calibrator, corona unit, draw-gear, trimming device and the wrap-up arranged successively along film throughput direction, it is characterized in that: also comprise being arranged between quenching shaping equipment and calibrator hot-rolling and for the apparatus of oxygen supply to corona unit supply oxygen.
Further, described corona unit comprises and is formed with the housing of film import and export and is arranged at the discharge tube in housing, and apparatus of oxygen supply output is communicated with housing by pipeline and is used for to housing supply oxygen.
Further, described hot-rolling is for adopting conduction oil heat supply.
Further, between described trimming device and wrap-up, be provided with bowed roller
The utlity model has following beneficial effect:
Between quenching shaping equipment and calibrator, hot-rolling is set, this hot-rolling can provide certain energy to film, make film that secondary crystallization behavior occur fast, secondary crystallization is occurred on production line, instead of after rolling rolls off the production line, avoided the roll off the production line possibility of the wrinkle in post curing process of product, shortened the slaking cycle simultaneously, can cut at short notice operation, the utility model, by improving the slaking cycle that has greatly shortened original needs, can foreshorten to 20h by the curing time of original 24-48h; Apparatus of oxygen supply can be to corona unit oxygen supply in addition, thereby improves film free radical and corona in air product (ozone) is oxidized, cross-linking reaction, at film surface polarization group, and raising surface tension.Due to the raising of oxygen content, increase the concentration of chemical reaction, obtain the polar group of a greater number, make film surface produce higher surface tension, and can be because of the excessive film breakdown that causes of voltage.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Shown in Fig. 1, a kind of polypropylene film curtain coating production line, comprise extruder 1, quenching shaping equipment, secondary crystallization hot-rolling 4, calibrator 5, corona unit 6, apparatus of oxygen supply 7, draw-gear 8, trimming device 9, bowed roller 10 and the wrap-up 11 arranged successively along film throughput direction, quenching shaping equipment comprises chill roll 2 and chill roll 3.
Corona unit 6 comprises and is formed with the housing of film import and export and is arranged at the discharge tube in housing, and apparatus of oxygen supply 7 outputs are communicated with housing by pipeline, and for to housing supply oxygen, hot-rolling 4 adopts conduction oil heat supply, and temperature is controlled at 35-45 DEG C.
The above, it is only preferred embodiment of the present utility model, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
