Abstract

The utility model discloses a conical single-screw plastic mixing extrusion device, which comprises a screw barrel (1) and a screw (2), wherein the side wall of a rear end of the screw barrel (1) is provided with a feed port (3). The conical single-screw plastic mixing extrusion device is characterized in that a cavity of the screw barrel (1) is a conical cavity (4); the screw (2) is a conical screw which is matched with the conical cavity (4) of the screw barrel (1); and the internal diameter of the thread of the screw barrel (1) is the same as the size of the external diameter of the thread of the screw (2). Compared with the parallel double screws or conical double screws used at present, the conical single-screw plastic mixing extrusion device has the characteristics of simple structure, low production cost, easiness in machining and long service life, and can be widely applied to mixing extrusion machining of a multi-component plastic raw material of high volatility, large compression ratio and low melt index.

Description

The single screw rod plastic cement of a kind of taper mixing extrusion device
Technical field
The utility model relates to a kind of plastic cement mixing extrusion device, the specifically a kind of single screw rod plastic cement of taper mixing extrusion device that is applicable to high volatilization, big compression ratio, multi-component plastic material that melt index is lower.
Background technology
In the processing of plastic material, to the processing of height volatilization, big compression ratio, multi-component plastic material that melt index is lower difficulty relatively.At present utilize parallel double-screw or conical double screw extruder to process mostly, the weak point of its existence to extruding of this type of plastic material: the one, the used equipment investment of processing parallel double-screw or conical double-screw is big, energy consumption is big, the equipment attrition degree is high; The 2nd, the service life of parallel double-screw and conical double-screw is short, production cost is high.
Summary of the invention
The purpose of the utility model is the defective to prior art, provide a kind of simple in structure, production cost is low, the single screw rod plastic cement of the taper mixing extrusion device of processing and long service life easily.
The purpose of the utility model solves through following technical scheme:
The single screw rod plastic cement of a kind of taper mixing extrusion device comprises barrel and screw rod, and the rear end sidewall of barrel is provided with charge door, and the inner chamber that it is characterized in that said barrel is a conical cavity.
The conical screw of described screw rod for matching with the conical cavity of barrel.
The screw thread interior diameter of said barrel is identical with screw flight overall diameter size.
The utility model is compared prior art has following advantage:
The utility model is compared with the parallel double-screw or the conical double-screw of present use; Have simple in structure, production cost is low, the processing and the characteristics of long service life easily, processing is extruded in the mixing that can be widely used in high volatilization, big compression ratio, multi-component plastic material that melt index is lower.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Wherein: 1-barrel; 2-screw rod; 3-charge door; 4-conical cavity.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: the single screw rod plastic cement of a kind of taper mixing extrusion device; Comprise barrel 1 and screw rod 2; The rear end sidewall of barrel 1 is provided with charge door 3, and wherein the inner chamber of barrel 1 is a conical cavity 4, the conical screw of screw rod 2 for matching with the conical cavity 4 of barrel 1; Be that the diameter of screw rod 2 is dwindled gradually by rear end to front end and constitutes cone-shapedly, and the screw thread interior diameter of barrel 1 is identical with the outside diameter of thread size of screw rod 2.Barrel 1 all adopts extraordinary rigid material to process with screw rod 2.When using the single screw rod plastic cement of this taper mixing extrusion device; Insert plastic material in the conical cavity 4 of barrel 1 from charge door 3; Screw rod 2 rotates under the drive of motor; Plastic material is extruded after compacting between the outer surface of the inwall of barrel 1 and screw rod 2, mixing, devolatilization, plasticizing under the promotion of the thread groove on the screw rod 2.The utility model is compared with the parallel double-screw or the conical double-screw of present use; Have simple in structure, production cost is low, the processing and the characteristics of long service life easily, processing is extruded in the mixing that can be widely used in high volatilization, big compression ratio, multi-component plastic material that melt index is lower.
The technology that the utility model does not relate to all can realize through prior art.
