Description
Technical field
This utility model relates to a kind of Secondary water-bath heating PVC heat shrink films process equipment.
Background technology
The shrinkage factor of PVC heat shrink films, contractility 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 thin film based packaging material.
PVC heat shrink films molding mode can be classified as two big classes, i.e. blowing (secondary inflation) molding and calendering (curtain coating) drawing and forming.Blow molding, process equipment is simple, reduced investment, and the thin 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
This utility model is in order to solve the Secondary water-bath heating PVC heat shrink films process equipment that problem above provides a kind of compact conformation, thin film thickness difference is little, Film shrinkage controls accurately, thin film good mechanical property, mixing shear property model are little.
The technical solution of the utility model is: described equipment includes extruder, blown-film die, first film bubble assembly, second film bubble assembly, 3rd carry-over pinch rolls, winder, it is provided with static mixer between described extruder and blown-film die, described blown-film die outfan connects the first film bubble assembly, the first described film bubble assembly and the second film bubble assembly are connected, at the film roll that the second described film bubble assembly is connected on winder by the 3rd carry-over pinch rolls, the first described film bubble assembly includes cooling vane, first film bubble, the first letter stencil and the first carry-over pinch rolls, the second described film bubble assembly includes the second carry-over pinch rolls, heating water tank, sizing coolant jacket, second film bubble and the second collapser.
Described static mixer is arranged in extruder barrel, and static mixer one end is connected with extruder screw head combination 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.
Melt is divided into some stock material stream by static mixer by this utility model, make its flow passage formed along distortion element, stream does revolution flowing also relative to the spiral curve of distortion element simultaneously, and the upset of melt result in radially mixing, improves melt mixed homo-effect.Melt, in static mixer, is dependent on the energy of flow of self and carries out mixing, therefore shear action is relatively low, and metallic pigments powder will not cause further shear property model, promote melt mixed, homogenizing, it is to avoid the shear property model of metal powder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is extruder, and 2 is blown-film die, and 3 is cooling vane, 4 is the first film bubble, and 5 is the first letter stencil, and 6 is the first carry-over pinch rolls, 7 is the second carry-over pinch rolls, 8 is heating water tank, and 9 is sizing coolant jacket, and 10 is the second film bubble, 11 is the second collapser, 12 is the 3rd carry-over pinch rolls, and 13 is film roll, and 14 is winder.
