Abstract
The invention discloses a novel multi-layer plastic extrusion device which belongs to the technical field of plastic extrusion, and solves the problems that weld marks are generated in the conventional plastic extrusion forming and the product quality is low in the market. The device comprises an engine base, wherein a bracket is arranged on the engine base; a motor box is arranged on the bracket; a conical sleeve is connected to the front side of the motor box. The device is characterized in that the conical sleeve comprises three layers; the middle layer is a rotating conical sleeve; an inner fixing conical sleeve and an outer fixing conical sleeve are respectively arranged on the inner layer and the outer layer of the rotating conical sleeve; spiral material conveying channels are respectively formed between the inner surface of the rotating conical sleeve and the outer surface of the inner fixing conical sleeve as well as between the outer surface of the rotating conical sleeve and the inner surface of the outer fixing conical sleeve. Weld marks on a product produced by using the device are effectively eliminated, the product quality is improved, and in addition, the quality of the product is further improved as filtering nets are arranged in the feeding ports of the feeding channels, so that the working efficiency is indirectly improved.
Description
Technical field
The invention belongs to extrusion technology field, a kind of laminated plastics extrusion device relating to.
Background technology
As everyone knows, the common individual layer extrusion molding machine head of application is by outer sleeve in the market, screw rod, the formations such as current divider support, can only carry out the individual layer extrusion molding of plastics, carrying out laminated plastics moulding extrudes and needs multiple devices to work simultaneously, reason due to flow divider for nose supporting structure, can not eliminate the weld mark of goods, material, because of the phenomenon of the long degraded of heated time, has affected operating efficiency, the quality of energy resource consumption and product, the plastic product impurity of the production of existing extruder is too many in addition, can have influence on quality and the appearance of product.
Summary of the invention
For the deficiency existing in background technology, the object of the present invention is to provide and a kind ofly can carry out the extrusion molding apparatus of laminated plastics extrusion molding simultaneously.
For achieving the above object, the invention provides following technical scheme: a kind of novel multilayer extrusion shaped device, comprise support, on support, be provided with support, on support, be provided with motor housing, the front side of motor housing is connected with conical sleeve, described conical sleeve comprises three layers, intermediate layer is rotary conic sleeve, inside and outside two-layer fixedly the inner conical sleeve and fixedly male-tapered sleeve of being respectively arranged with at rotary conic sleeve, and the inner surface of rotary conic sleeve, outer surface respectively with the fixing outer surface of inner conical sleeve, fixedly between the inner surface of male-tapered sleeve, be formed with material helical feed runner.
The surfaces externally and internally of above-mentioned rotary conic sleeve is provided with spiral groove, with it coaxial fixedly inner conical sleeve outer surface and fixedly male-tapered sleeve interior surface be provided with corresponding longitudinal groove.
On conical sleeve, be provided with charging runner, and be provided with screen pack in the charging aperture position of charging runner.
In above-mentioned motor housing, be provided with motor, the work of driven by motor rotary conic sleeve.
The present invention's beneficial effect is compared to existing technology: the product that the present invention produces has been eliminated weld mark effectively, improved product quality, in the charging aperture position of charging runner, be provided with screen pack in addition, further improved the quality of product, indirectly improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present invention;
Fig. 2 is two of structural representation of the present invention.
Number in the figure implication: 1-is inner conical sleeve fixedly; 2-is male-tapered sleeve fixedly; 3-rotary conic sleeve; 4-support; 5-support; 6-motor housing; 7-conical sleeve; 8-charging aperture.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As Figure 1-Figure 2, a kind of novel multilayer extrusion shaped device, comprise support 5, on support 5, be provided with support 4, on support 4, be provided with motor housing 6, the front side of motor housing 6 is connected with conical sleeve 7, described conical sleeve 7 comprises three layers, intermediate layer is rotary conic sleeve 3, inside and outside two-layer fixedly the inner conical sleeve 1 and fixedly male-tapered sleeve 2 of being respectively arranged with at rotary conic sleeve 3, and the inner surface of rotary conic sleeve 3, outer surface respectively with the fixing outer surface of inner conical sleeve 1, fixedly between the inner surface of male-tapered sleeve 2, be formed with material helical feed runner.
The surfaces externally and internally of above-mentioned rotary conic sleeve 3 is provided with spiral groove, with it coaxial fixedly inner conical sleeve 1 outer surface and fixedly male-tapered sleeve 2 inner surfaces be provided with corresponding longitudinal groove.
On conical sleeve 7, be provided with charging runner, and be provided with screen pack in charging aperture 8 positions of charging runner.
In above-mentioned motor housing 6, be provided with motor, 3 work of driven by motor rotary conic sleeve.
In extrusion of the present invention, two kinds of different materials are respectively since the large end of conical sleeve 7 enters independently inside and outside conical sleeve (1; 2) and the geometry passages spiral that forms of rotary conic sleeve 3 be fed forward.Externally under heating and the effect of internal shear heat, plastifying fusion little by little.The material of plastifying fusion, is transported to the front end of tapered sleeve 7, is merged into as one deck material combining.Through head, by certain geometric cross section and size, extrude continuously, form the composite article that two kinds of different materials form.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and modification, these of above-mentioned hypothesis improve and modification also should be considered as protection scope of the present invention.
