Description
Technical field
This utility model relates to a kind of screw rod, is specifically related to film forming molten resin extrusion device.
Background technology
At present, existing extrusion device includes transport pipeline, the screw rod being arranged in transport pipeline, and gives the heater of transport pipeline heating and thermal insulation.Screw rod of the prior art is all to use the body of rod and the screw thread composition being arranged on the body of rod, and the spacing between screw thread is consistent.Existing screw rod can only reach the function of extrusion, and owing to the spacing of screw thread is consistent, present in molten resin, the bubble then screw thread on screw rod is transported in next step, and then affects the quality of resin later stage film forming.
Utility model content
The bubble that this utility model exists in mainly solving the molten resin in existing extrusion device can be transported in next step by the screw thread on screw rod, and then the problem affecting last resin later stage quality of forming film, it is provided that a kind of film forming molten resin extrusion device solving the problems referred to above.
This utility model is achieved through the following technical solutions:
Film forming molten resin extrusion device, including support body, the transfer passage being arranged on support body, the extrusion screw rod body being arranged in transfer passage, drive the driving motor of extrusion screw rod body, be arranged on the charger of transfer passage porch, and the heater being arranged on transfer passage；
Described extrusion screw rod body includes the body of rod and the screw element being arranged on the body of rod；The quantity of described extrusion screw rod body is two or more, and these plural extrusion screw rod body head and the tail connect；Between said two extrusion screw rod body, junction is additionally provided with barriers；Described barriers, by connecting rod, is arranged on the raised line composition of connecting rod outer surface.
By the setting of this barriers in this utility model, not only it is only capable of effectively preventing from carrying the generation of bubble in extrusion, it is to avoid bubble is on the impact of quality during film forming；And by the setting of this structure, moreover it is possible to preferably non-molten resin is got rid of, it is to avoid the unmelted resin granules impact on quality of forming film.
Described raised line is that 30～45 degree of angles are arranged with the axis of connecting rod.The quantity of described raised line is more than three, and the distance being evenly distributed between connecting rod outer surface, and adjacent two raised lines is not less than on screw element the 1/4 of the spacing of adjacent two spirals.
The pressure range that be can guarantee that in course of conveying in this screw rod by the setting of said structure is less, meets the pressure stability of extrusion liquid, and then the quality of film forming is effectively ensured.
Preferably, described screw element having the groove arranged along this hand of spiral, the width of described groove reduces after being gradually increased along screw element.
This utility model change by groove width, can effectively intercept the non-molten resin that granule is bigger, and matched by the heater on extrusion device, by the non-molten resin heating and melting again of smaller particle, and then effectively prevent that the resin extruded by extrusion device has 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:
1, by the setting of this barriers in this utility model, not only it is only capable of effectively preventing from carrying the generation of bubble in extrusion, it is to avoid bubble is on the impact of quality during film forming；And by the setting of this structure, moreover it is possible to preferably non-molten resin is got rid of, it is to avoid the unmelted resin granules impact on quality of forming film；
2, this utility model being preferably provided with by barriers structure, the pressure range that can guarantee that in course of conveying in this screw rod is less, meets the pressure stability of extrusion liquid, and then the quality of film forming is effectively ensured.
