The specific embodiment
Embodiment 1
Shown in Fig. 1,2,3, the utility model provides a kind of head of extruder, comprise major ingredient core rod 1, major ingredient die sleeve 2, auxiliary material core rod 3, sleeve 4, connecting plate 5, discharging core rod 6, major ingredient core rod 1 is enclosed within major ingredient die sleeve 2, major ingredient die sleeve 2 is fixed together with extruder main feed device, and the charging aperture of major ingredient core rod 1 coordinates docking with the feeding port of extruder main feed device; Between major ingredient core rod 1 outer surface and major ingredient die sleeve 2 inner surfaces, form a runner, this runner is for the conveying of auxiliary material; Auxiliary material core rod 3 one sides coordinate docking with the feeding port of extruder auxiliary material pay-off, one side and institute's major ingredient die sleeve 2 are bolted to connection, wherein major ingredient die sleeve 2 sides are provided with a charging aperture, be connected with auxiliary material core rod 3 discharging openings, feeding that can be smooth is to the runner of major ingredient core rod 1 outer surface and the 2 inner surfaces formation of major ingredient die sleeve; Sleeve 4 fixed covers, outside major ingredient die sleeve 2 and discharging core rod 6, play the fixedly effect of discharging core rod 6, connecting plate 5 for the docking of mould, the material of final molding is delivered on mould, discharging core rod 6 is through connecting plate 5, and is closely connected with connecting plate 5.The sectional area of discharging core rod 6 and runner is set to duck's egg circle, and making final material shape is that duck's egg is circular, conveniently on mould, makes afterwards three layers of finished product; The bore of major ingredient core rod 1 is greater than the bore of auxiliary material core rod 3.
The course of work of this example: when extruder main feed device and extruder major ingredient drawing mechanism start feeding, major ingredient is transported to interflow by major ingredient core rod 1 always and locates, auxiliary material is transported to interflow by auxiliary material core rod 3 and locates, forming inside is the finished-product material of the outside duck's egg circle for auxiliary material of major ingredient, by discharging core rod 6, be delivered on mould again, complete the processing of product.
The present embodiment provides a kind of head of extruder, and its Structural Tectonics is identical with embodiment 1 structure, and difference is that the bore of major ingredient core rod 1 is less than the bore of auxiliary material core rod 3.
The present embodiment provides a kind of head of extruder, and its Structural Tectonics is identical with embodiment 1 structure, and difference is that the bore of major ingredient core rod 1 and the caliber size of auxiliary material core rod 3 equate.
In sum, can adjust the caliber size of major ingredient core rod 1 and auxiliary material core rod 3, adjust the thickness of major ingredient layer and auxiliary material layer, when the bore of major ingredient core rod 1 is greater than the bore of auxiliary material core rod 3, from mould finished product major ingredient layer thickness out, be greater than auxiliary material layer thickness, form the thin product in thick middle both sides; When the bore of major ingredient core rod 1 is less than the bore of auxiliary material core rod 3, from mould finished product major ingredient layer thickness out, be less than auxiliary material layer thickness, form the thick product in intermediate thin both sides; When the bore of major ingredient core rod 1 the same with the bore of auxiliary material core rod 3 when large, the same with auxiliary material layer thickness from mould finished product major ingredient layer thickness out, form the products of three layers of the same thickness.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
