Description
Technical field
The present invention relates to a kind of infrared ray reheating blowing PVC heat shrink films making apparatus.
Background technology
The shrinkage factor of PVC heat shrink films, convergent force are moderate, and transparency is good, excellent in mechanical performance, and cost performance is high, is widely used in the packaging of the commodity such as daily chemical products, electronic apparatus, plastic cement hardware, glass ceramics.It not only has good protective effect to packing material, but also makes commodity profile more distinct attractive in appearance, lifts commodity packaging class, is current comparatively ideal film based packaging material.
PVC heat shrink films molding mode can be classified as two major classes, that is, be blow molded（Secondary inflation）Shaping and calendering（Curtain coating）Drawing and forming.Blow molding, process equipment is simple, reduced investment, and the film variety renovation produced flexibly, is more suitable for the processing of general shrink wrap material.Calendering（Curtain coating）Drawing and forming mode, processing is fine, and film product wide cut is big, thickness good evenness, but equipment is more, long flow path, and investment is big, and operating cost is high.
The content of the invention
The present invention provides the small infrared ray reheating blowing PVC heat shrink films making apparatus of a kind of compact conformation, small film thickness difference, uniform coloring, film good mechanical property, mixing shear property model to solve problem above.
The technical scheme is that：Infrared ray reheating blowing PVC heat shrink films making apparatus, described equipment includes hopper, extruder, blown-film die, first film bubble component, second film bubble component, 3rd carry-over pinch rolls, cooling device and crimping device, static mixer is provided between described extruder and blown-film die, described blown-film die output end connects the first film bubble component, the first described film bubble component is connected with the second film bubble component, the first described film bubble component includes the vane being sequentially connected, first film bubble, first collapser, first carry-over pinch rolls, the second described film bubble component includes the second carry-over pinch rolls, far infrared heater, baking oven, second film bubble, assisted heating device, upper cooling vane, lower cooling vane, foam-stabilizing device and the second collapser.
Described static mixer is arranged in extruder barrel, and static mixer one end is connected with extruder screw head combined type, and the static mixer other end is connected by flange with blown-film die linkage section.
Described static mixer diameter is identical with extruder barrel.
Described far infrared heater is arranged on baking oven top, and described assisted heating device is arranged on baking oven inwall, and described baking oven bottom sets upper cooling vane and lower cooling vane, and the second described film bubble both sides are provided with multiple foam-stabilizing devices.
Compact conformation of the present invention, film thickness difference are small, Film shrinkage controls accurate, film good mechanical property, mixing shear property model is small.
