Description
Technical field
The utility model relates to a kind of infrared ray secondary heating 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 five metals, glass ceramics.It not only has good protective effect to packing material, but also makes commodity profile the distinctest attractive in appearance, promotes commodity packaging class, is current comparatively ideal film based packaging material.
PVC heat shrink films molding mode can be classified as two big classes, i.e. blowing (secondary inflation) and is molded and rolls (curtain coating) drawing and forming.Blow molding, process equipment is simple, reduced investment, and the film variety renovation produced is flexible, 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 many, long flow path, and investment is big, and operating cost is high.
Utility model content
The utility model in order to solve problem above and provide that a kind of compact conformation, film thickness difference is little, uniform coloring, film good mechanical property, infrared ray secondary heating blowing PVC heat shrink films making apparatus that mixing shear property model is little.
The technical solution of the utility model is: infrared ray secondary heating blowing PVC heat shrink films making apparatus, described equipment includes hopper, extruder, blown-film die, first film bubble assembly, second film bubble assembly, 3rd carry-over pinch rolls, cooling device and crimping device, it is provided with static mixer between described extruder and blown-film die, described blown-film die output connects the first film bubble assembly, the first described film bubble assembly and the second film bubble assembly are connected, the first described film bubble assembly includes the vane being sequentially connected with, first film bubble, the first letter stencil, first carry-over pinch rolls, the second described film bubble assembly 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 with blown-film die linkage section by flange.
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 arranges cooling vane and lower cooling vane, and the second described film bubble both sides are provided with multiple foam-stabilizing device.
The utility model compact conformation, film thickness difference are little, Film shrinkage controls accurately, film good mechanical property, mixing shear property model are little.
