Description
Technical field
The utility model relates to a kind of Electromagnetic Heating coil apparatus, particularly a kind of Electromagnetic Heating coil apparatus manufacturing PVC heat shrinkable printed film.
Background technology
PVC heat shrinkable printed film is mainly used in bottled drink label, major product " Chef Kang " series of labels, " Wahaha " series of labels, " unification " series of labels, " unification ", " NongFuShanQuan ", " Coca-Cola " series of labels, this film has the advantages that transparency is high, appropriateness is bright and clean and sealing is strong.
As shown in Figure 1, in PVC heat shrinkable printed film manufacture process, employing equipment is divided into host machine part and subsidiary engine part, and wherein, host machine part comprises: the extruder 1 of included screw rod and mould; Mould comprises: drainage plate 2, current divider 3, core rod 4 and die sleeve 5 etc.; Subsidiary engine part comprises: front haulage rubber tire and herringbone clamping plate 6, heating water tank and traction 7, rear haulage and herringbone clamping plate 8, linearity control device 9, bellows 10 and screw feeding machine 11.
Front haulage is mainly used in drawing from extruding machine mold drum film out, flattens rear haulage and heating water tank transmission through front herringbone clamping plate; Heating water tank traction is mainly used in film heating, expansion, and in heating water tank, have shaping cover device, the film after making it add thermal enlargement is shaped through shaping cover.Rear towing device is used for film and flattens, and makes it to be filled with gases at high pressure and is expanded to rear herringbone clamping plate and flattens, complete a film-forming process.
The major function of heating collar is by PVC powder heating in extruding machine barrel.Then transfer to inner mould core by extruder to carry out shunting and expanding.Above-mentioned heating collar structure of the prior art as shown in Figure 2, comprises barrel 120, is wound with heating collar 110 at the perficial helical of barrel 120.There is following shortcoming in this structure: original resistance has heating to be heated inequality, and heat conduction is slow, and the life-span is short, energy consumption is high, and heat waste is large, the problem that ambient temperature is high, therefore, a kind of Electromagnetic Heating coil apparatus manufacturing PVC heat shrinkable printed film of special needs, to solve above-mentioned existing Problems existing.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of Electromagnetic Heating coil apparatus manufacturing PVC heat shrinkable printed film, for the deficiencies in the prior art, effectively increase heating efficiency, and homogeneous heating, significantly can reduce the heating-up time, improve product yield, improve the quality of product.
To achieve these goals, the technical solution of the utility model is as follows:
PVC heat shrinkable printed film Electromagnetic Heating coil apparatus, is characterized in that, be equidistantly arranged at intervals with some groups of electromagnetic heating coils on the surface of extruding machine barrel, be outside equipped with insulation shell at this section of electromagnetic heating coil.
In the utility model, the width of spacing distance and electromagnetic heating coil between described two adjacent groups electromagnetic heating coil self is consistent.
The heating collar device of manufacture PVC heat shrinkable printed film of the present utility model, compared with prior art, heating is more even, and the thermal efficiency is high, and corrosion resistance is better, and the yield rate of controlling diaphragm effectively, improves the quality of product, realize the purpose of this utility model.
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better embodiment of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is the structural representation manufacturing PVC heat shrinkable printed film equipment in prior art;
Fig. 2 is heating collar structural representation of the prior art;
Fig. 3 is schematic diagram of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 3, PVC heat shrinkable printed film Electromagnetic Heating coil apparatus, be equidistantly arranged at intervals with some groups of electromagnetic heating coils 210 on the surface of extruding machine barrel 200, be outside equipped with insulation shell 220 at this section of electromagnetic heating coil.
The width of the spacing distance between two adjacent groups electromagnetic heating coil and electromagnetic heating coil self is consistent.
The utility model is with PVC powder in electromagnetic heating coil 210 heated extruder barrel 200, and the PVC plastic melt after heating in barrel is transferred to inner mould core by extruder to carry out shunting and expanding.
The heating collar device of manufacture PVC heat shrinkable printed film of the present utility model, compared with prior art, heating is more even, and the thermal efficiency is high, and corrosion resistance is better, and the yield rate of controlling diaphragm effectively, improves the quality of product, realize the purpose of this utility model.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
