Summary of the invention
The bubble existed in having present invention mainly solves 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 protecting film shaped device based on extrusion screw rod solving the problems referred to above.
The present invention is achieved through the following technical solutions:
Protecting film shaped device based on extrusion screw rod; including the extruder being sequentially arranged, control die head, roller, winder; described extruder includes the transfer passage with charge door; the extrusion screw rod body being arranged in transfer passage; drive the driving motor that extrusion screw rod body rotates, 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 the present invention, 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.
The present invention 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.
In order to be able to reach optimal cooling effect, being provided with cooling water circulating device in described roller, this cooling water circulating device is prior art, thus its structure repeats no more in the present invention.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, by the setting of this barriers in the present invention, 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, the present invention 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.
