The device of the latter shaping, so head is crucial, excellent, the overall level of direct decision device of its performance.
Domestic handpiece structure can only accomplish that three layers of confession are squeezed at present, and five layers of precision is very low, available reluctantly, and due to stream
Road is grown, and ectonexine runner differs greatly, and outer layer makes material easily degrade, and causes to need the trouble of frequent disassembly, cleaning head, head
Cleaning it is very time-consuming, labor intensity is big, even if the degraded of wherein one layer of material, whole head also need whole disassembly, cleaning, and every
Laminar flow road pressure flow velocity can not adjust.Therefore each layer face tension force is influenceed, is easily peeling phenomenon.
Other every layer of temperature of head can not be controlled individually, such as：Nylon processing temperature needs 250 DEG C, and 150 DEG C of polyethylene is most
Every layer of temperature of charge difference is managed, differs 100 DEG C, therefore the temperature of whole handpiece body needs 250 DEG C, can only be by highest material solution temperature
Degree setting, it is totally unfavorable to low-temperature material.And because the limitation of structure, every layer of circumference deviation of head are larger.Particularly price
High resin, it is impossible to meet the requirement of very thin thickness.Also head is taken interior cold highly difficult, influences yield, influences transparency.
The shortcomings that being current head above and deficiency, processing efficiency and crudy are had a strong impact on, especially in food
Field, the outer packing processing request of food is more strict, and the head actually used at present is unable to reach at all.

Portion, the spacing protruding parts is in limited impression.
The quantity of the individual layer extrusion structure is 5-13 layers, and is sequentially connected in series setting.
This head is 200mm-350mm suitable for product initial diameter.
The beneficial effects of the utility model are：
1 the technical program be my company absorbed according to Italy and Germany technology and transform produce be more suitable for the country
Use head.It can produce multi-layer co-extruded, various functions film, can be applicable a variety of industries.This product can produce various uses
Multifunctional membrane, such as：Packaging for foodstuff, industrial packaging, Militaryl package etc..
2 this products are made up of 13 groups of separate parts, then the extruder composition of 13 different models may be selected completely
Head, each part is made up of three parts（Each one of bolster, conveyor screw one）, carried out according to certain angle during assembling
Installation, also reasonable clearance is processed by the model of material, feature, extruder pressure etc. during processing, being allowed to head can be preferably
Work.
3 the technical program can control the temperature of individual layer respectively, so as to improve equipment because every layer is separate feeds
Overall processing precision.
4 the technical program are overlaying structure, the quantity that can set single layer structure according to being actually needed, enhance equipment
Applicability.
The handpiece structure of 5 our company design, overcomes the heaviness of traditional Die Design, complicated, not easy processing, uses
The shortcomings of family is not easy to assemble, and cost is too high, this product is simple in construction, easily fabricated, fault rate is low, safe and reliable, energy-conserving and environment-protective,
It is easy to operation.
