The system is provided with eleven compound layers, the runner system with different exchange of the compound proportion can solve the problem that foreign countries are at the monopoly position for the multi-layer coextrusion high-resistance membrane production line at home, and saves a great amountof energy resources and production cost in domestic food package market.

Description

A kind of eleventh floor co-extrusion runner system

Technical field:

The utility model relates to the thin film fabrication techniques field, refers in particular to a kind of ten co-extrusion runner systems.

Background technology:

Traditional packaging material for food depends on the compound requirement of satisfying packaging for foodstuff of dry type of multiple film and barrier material always, but, dry type is compound because the rising of material cost, and exist recombination process waste of raw materials and compound tense to have problems such as dissolvent residual, can not satisfy the requirement of packaging for foodstuff.At present, multi-layer co-extruded high-isolation film substitutes the compound barrier material of dry type gradually, still, and the Chang Yong three layers of composite material film requirement that can not satisfy some special multilayers and polychrome to the five-layer co-squeezing flow passage system in the market.

The utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, the eleventh floor co-extrusion runner system that provides a kind of composite material film that satisfies some special multilayers and polychrome to require.

For achieving the above object, the technical scheme that the utility model provides is: a kind of eleventh floor co-extrusion runner system, this system is mainly by distributor, adapter, three runner die heads are formed, it is characterized in that: the runner switching valve is fixed in the main hole of dispenser top, nine laminar flow roads are set in the distributor altogether, the layer 6 runner is positioned at the center, other runner is the clothes hanger type for one group around layer 6 runner two twenty percents and arranges successively from inside to outside, wherein, layer 5 runner and layer 7 runner are first group, the 4th laminar flow road and the 8th runner are second group, and the 3rd runner and the 9th runner are the 3rd group, and second runner and the tenth laminar flow road are the 4th group; First flow and the 11 runner pass in the distributor and stretch in the three runner die heads, and the die head compression section that first flow and the 11 runner and above-mentioned five groups of runners converge in the three runner die heads is jointly converged; The adapter one side is connected with main distributor, and another side is connected with three runner die heads.

Between described second layer runner to the ten laminar flow roads are whenever two-layer current divider and distribution pin are set.

The die lip mouth of described three runner die heads also is provided with the automatic regulator of die lip aperture.

The utlity model has the compound number of plies of eleventh floor, the flow passage system of the conversion of different composite ratio can solve external monopoly position to domestic multi-layer co-extruded high-isolation film production line, is the saving of domestic food the packaging market a large amount of energy and production cost.

Description of drawings:

Fig. 1 is the utility model structural representation.

The specific embodiment:

Shown in accompanying drawing 1, present embodiment mainly is made up of distributor 100, adapter 200, three runner die heads 300, runner switching valve 400 usefulness screws are fixed in the main hole at distributor 100 tops, runner switching valve 400 can process the runner order that is fit to technological requirement, if need convert other runner orders to, need only change a runner switching valve and get final product.Nine laminar flow roads are set in the distributor 100 altogether, layer 6 runner 106 is positioned at the center, other runner is the clothes hanger type for one group around 106 liang of twenty percents of layer 6 runner and arranges successively from inside to outside, wherein, layer 5 runner 105 and layer 7 runner 107 are first group, the 4th laminar flow road 104 and the 8th runner 108 are second group, and the 3rd runner 103 and the 9th runner 109 are the 3rd group, and second runner 102 and the tenth laminar flow road 110 are the 4th group; First flow 101 and the 11 runner 111 pass in the distributor 100 and stretch in the three runner die heads 300, and first flow 101 and the 11 runner 111 converge with the die head compression section 301 that above-mentioned five groups of runners converge in the three runner die heads 300 jointly, during work, fluid converges at this place, and extrudes by the die lip mouth; Adapter 200 one side is connected with distributor 100 main bodys, and another side is connected with three runner die heads 300, the main effect of distributor 200 be the assurance distributor material by the streamline channel in the adapter 200 can smooth and easy arrival three runner die heads die cavity.The design of three runner die heads 300 is that the material according to the viscosity/shearing rate of material and various different characteristics carries out different manufacturing and designing, and also is provided with the automatic regulator 302 of die lip aperture at the die lip mouth of three runner die heads 300.Described second layer runner 102 to the tenth laminar flow roads 110 are every to be provided with current divider 112 and distribution pin 113 between two-layer, regulate the angle of catch in the current divider and can control ratio outer and internal layer, distribution pin 113 can be regulated flowing velocity and bed thickness outer and the internal layer melt.Have 8 adjustable current dividers in outside and 8 in the described main body and can regulate distribution pin, die head adapter one side is connected with main distributor, and another side is connected with three runner die heads, and it also is equipped with the self-checking device of die lip aperture.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
