Accompanying drawing explanation
Fig. 1 is the overall structure figure of the utility model production line.
Detailed description of the invention
By below to the description of embodiment; to more contribute to public understanding the utility model; but the restriction that the specific embodiment given by applicant can't be considered as technical solutions of the utility model, any definition to parts or technical characteristic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
As shown in Figure 1, the PVC cast film line of Planetary Screw Extruder is adopted to comprise a Planetary Screw Extruder, Planetary Screw Extruder inside is provided with fluxing zone, driving screw, planetary-screw and heating oil, the periphery of planetary-screw is provided with internal tooth casing, planetary-screw is respectively with driving screw, internal tooth casing with engage each other, Planetary Screw Extruder is connected with a screw melt pump, also comprises film devices for taking-up, sheet edge cutting device and film cooling draw-gear.
PVC material is the one of charge of plastics.PVC is the abbreviation of pvc material, is be primary raw material with Corvic, adds appropriate age resister, modifier etc., become corresponding PVC plastic goods through the technique such as mixing, calendering, vacuum forming, curtain coating.
Cast film is a kind of tensionless winkler foundation, the nondirectional flat crowded film produced by melt salivation quenching, has individual layer to salivate and multi-layer co-extruded salivation two kinds of modes.Its feature is that speed of production is fast compared with blown film, and output is high, and the transparency, glossiness, thickness evenness etc. of film are all very outstanding.Cast film has superior heat sealability and the excellent transparency, and be one of main packaging composite base material, for the production of Tropical cooking film, vacuum plated aluminum film etc., market prospects are extensive.
Embodiment 1:
Production line comprises following part and the course of work:
1) feeding device: the powdery that mixture is good or granulated plastic are transported to extruder pusher section entrance by the feeding device on hopper;
2) Planetary Screw Extruder: fluxing zone sent into by the plastics that hopper is sent here by the pusher section of Planetary Screw Extruder, fluxing zone is the core component of Planetary Screw Extruder, all be connected with heating oil in driving screw and internal tooth casing, its temperature can regulate according to the difference of plastics variety.The plastics entering fluxing zone pass through extruding, shearing, mixing and heat effect in the rotation of driving screw and planetary-screw, become molten condition when arriving planetary extruder discharge end.
3) screw melt pump: play voltage stabilizing and build pressure effect, provides stable extrusion pressure and stable flow to melt.
4) cast film head: the profiled part being plastic sheet, film, the plastics of melting become the shape of needs through head.Size.
5) film two-way stretch device: film carries out horizontal and vertical stretching, makes film reach expection thickness, film thickness evenly, transparency is higher, intensity is higher.
6) film cooling, draw-gear: film carried out cooling and shaping, guide to devices for taking-up.
7) sheet edge cutting device: cut away by film edge redundance, makes film edge neat.
8) film devices for taking-up: film is collected rolling.
Embodiment 2:(does not comprise biaxial orientation process), this production line comprises following part and the course of work:
Feeding device: the powdery that mixture is good or granulated plastic are transported to extruder pusher section entrance by the feeding device on hopper.
2) Planetary Screw Extruder: fluxing zone sent into by the plastics that hopper is sent here by the pusher section of Planetary Screw Extruder, fluxing zone is the core component of Planetary Screw Extruder, all be connected with heating oil in driving screw and internal tooth casing, its temperature can regulate according to the difference of plastics variety.The plastics entering fluxing zone pass through extruding, shearing, mixing and heat effect in the rotation of driving screw and planetary-screw, become molten condition when arriving planetary extruder discharge end.
