Abstract
The utility model relates to a co-extrusion blow molding machine head of a double-spiral-plane 2n-type structure runner, which improves a chute-type runner of an original co-extrusion film blow molding machine head. The runner is in a 2n-type plane structure in the modes of one divided into two, two divided into four and four divided into eight. The cross section of the runner is in a U-shaped design; the runner has fewer turning points and no dead angles; the structure can lead material heating to be more sufficient; the U-shaped design effectively improves material flowing performance; and materials are evenly distributed and heated inside the machine head by the aid of the 2n-type structure after entering the runner through a feed inlet, so that extruded film products are uniform in density.
Description
Technical field
The utility model relates to a kind of coextrusion blow machine head runner, is a kind of double spiral plane co-extrusion superposing type flow channel that relates to.
Background technology
Along with the development and the progress of society, people's quality of life is constantly improved, and is also more and more higher to various plastic film performance demands.The head of existing coextrusion blow unit all is inclined flow passage formula coextrusion blow machine heads, inclined flow passage formula coextrusion blow machine head is because flex point and dead angle are more, be easy to generate thickener, directly caused the situation of being heated of material in the head inhomogeneous, influenced the mobile performance of material, make the uniformity of discharging poor, uneven distribution, consequences such as the physical property difference of product.
The utility model content
The utility model provides a kind of seven-layer co-extrusion inflation film manufacturing machine flow channel at the problems referred to above, and its purpose is that the inclined flow passage design that is primarily aimed at existing inflation film manufacturing machine is not enough, and a kind of head pressed density height is provided, and flex point is few, the flow passage structure design at no dead angle.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of coextrusion blow machine head is provided, this head, include core, runner dish, take over a business, internal orifice mould, collar extension mould and copper rod form, the runner in the flow channel dish is distributed in same plane.
According to double spiral plane 2 described in the utility model
nType structure runner coextrusion blow machine head one optimal technical scheme: described runner is a double helix, and the cross section is the U type.
According to double spiral plane 2 of the present invention
nType structure runner coextrusion blow machine head one optimal technical scheme: described runner be one-to-two, two minutes four, four minutes eight 2
nThe type flow passage structure.
Beneficial effect of the present invention is: coextrusion blow unit inclined flow passage formula head different from the past, but Composite Double helical flow path structure; The head flex point is few, does not have the dead angle; U type pipeline is dispersed throughout runner dish, 2
nThe type structure helps to cause the discharging good evenness, and fineness is good, and thin and thick is even; The pressed density height, product tensile strength of producing and elongation at break height; Soffening is good, and defect ware reduces significantly.
Description of drawings
Fig. 1 is runner dish inner flow passage pipe profile figure of the present invention.
The 1-charging aperture
The 2-discharging opening
The specific embodiment
The double spiral plane 2 of the present invention's design
nType structure runner is positioned on the inflation film manufacturing machine runner dish 2
nThe type structural design, U type runner section.
Utilize the course of work of the present invention: thermoplastic is heated to molten condition through the pulverizing of hopper by extruder, enters in the head, by charging aperture, through helical planes 2 of the present invention
nBehind the type structure runner, extrude, adjust the goods minimal thickness,, form film with the vane cooling by internal orifice mould and the collar extension mould that settle the head upper end with the form of compound fluid shape.
The above; only be the preferable specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
