Abstract
The utility model discloses a bubble prevents that type from extruding screw rod has solved during the bubble that exists in the melting resin among the present extrusion device can the screw on the screw rod carries next step, and then influences the problem of last resin later stage film forming quality. The utility model discloses an extrude the screw rod body, it includes the body of rod (1) and sets up screw element (2) on the body of rod (1) to extrude the screw rod body, a serial communication port, the quantity of extruding the screw rod body is more than two, and this extrudes screw rod body end -to -end connection more than two, extrude that the junction still is provided with separation piece (4) between the screw rod body for two, separation piece (4) are set up and are constituteed at the sand grip of connecting rod surface by the connecting rod. The utility model has the advantages of pressure variation is little, prevent that the bubble from together transporting.
Description
Technical field
This utility model is related to a kind of screw rod and in particular to bubble prevents type extrusion screw rod.
Background technology
At present, existing extrusion device includes transport pipeline, is arranged on the screw rod in transport pipeline, and gives transport pipeline
The heater of heating and thermal insulation.Screw rod of the prior art is all using the body of rod and the screw thread composition being arranged on the body of rod, and spiral shell
Spacing between stricture of vagina is consistent.Existing screw rod can only reach the function of extrusion, and because the spacing of screw thread is consistent, melting
Bubble present in resin is then transported in next step along the screw thread on screw rod, and then affects the matter of resin later stage film forming
Amount.
Utility model content
The interior bubble existing of molten resin that this utility model mainly solves in existing extrusion device can be on screw rod
Screw thread be transported in next step, and then affect the problem of last resin later stage quality of forming film, provide a kind of solve above-mentioned
The bubble of problem prevents type extrusion screw rod.
This utility model is achieved through the following technical solutions：
Bubble prevents type extrusion screw rod, and including extrusion screw rod body, described extrusion screw rod body includes the body of rod and is arranged on
Screw element on the body of rod；The quantity of described extrusion screw rod body is two or more, this plural extrusion screw rod body head and the tail
Connect；Between described two extrusion screw rod bodies, junction is additionally provided with barriers；Described barriers by connecting rod, the company of being arranged on
The raised line composition of extension bar outer surface.
Pass through the setting of this barriers in this utility model, be not only only capable of the product effectively preventing from conveying bubble in extrusion
Raw, it is to avoid the impact to quality during film forming for the bubble；And by the setting of this structure moreover it is possible to preferably carry out to non-molten resin
Exclusion, it is to avoid the impact to quality of forming film for the unmelted resin granules.
Described raised line is in 30～45 degree of angle settings with the axis of connecting rod.The quantity of described raised line is more than three,
Be evenly distributed in connection rod outer surface, and the distance between two neighboring raised line not less than two neighboring spiral on screw element it
Between distance 1/4.
Can guarantee that the pressure range in this screw rod in course of conveying is less by the setting of said structure, meet extrusion
The pressure stability of liquid, and then the quality of film forming is effectively ensured.
Preferably, described screw element has the groove along the setting of this hand of spiral, the width of described groove is along spiral shell
Stricture of vagina part reduces after being gradually increased.
The change by groove width for this utility model, can effectively intercept the larger non-molten resin of granule, and by squeezing
The heater going out on device matches, and by the non-molten resin heating and melting again of smaller particle, and then effectively prevents from passing through
In the resin of extrusion device extrusion, there are non-melt granules.
Further, the width of described groove is not more than the spacing in screw element between two spirals.
This utility model compared with prior art, has such advantages as and beneficial effect：
1st, pass through the setting of this barriers in this utility model, be not only only capable of effectively preventing from conveying bubble in extrusion
Produce, it is to avoid the impact to quality during film forming for the bubble；And by the setting of this structure moreover it is possible to preferably enter to non-molten resin
Row exclusion, it is to avoid the impact to quality of forming film for the unmelted resin granules；
2nd, this utility model passes through being preferably provided with of barriers structure, can guarantee that the pressure in this screw rod in course of conveying becomes
Change scope is less, meets the pressure stability of extrusion liquid, and then the quality of film forming is effectively ensured.
