Abstract
The utility model discloses a conical single-worm plastic extrusion machine comprising a worm and a machine barrel, the outer circular face of the worm is a conical face, an inner hole of the machine barrel which engages with the worm is a conical hole, a charging worm and the diameter of the inner hole are bigger than a measuring worm and the diameter of the inner hole, an adjusting pad is arranged on the end of the feeding section of the worm and a thrust bearing box is arranged on the end of the feeding section of the machine barrel. Higher geometric compression ratio can be achieved, bigger torque can be born, the disassembly and cleaning of the conical worm is very convenient, the application is broader and the manufacturing efficiency is higher.
Description
The utility model relates to a kind of single-screw extruder, particularly a kind of improved taper single-screw extruder.
Existing single-screw extruder, because its screw rod cylindrical is a cylindrical surface, feeding section equates that with the metering section pitch diameter itself there is following several defective in its structure: be difficult to obtain bigger geometrical compression ratio 1.; 2. be difficult to bear than high pulling torque; 3. the gap length of screw rod and inner core can not be adjusted; 4. screw rod disassembly, cleaning inconvenience, thereby there is inconvenience in actual applications, as powder raw material, laminar raw material, the high raw material (as calcic-plastic composite material, Wood-plastic material) of filling are waited directly extrusion molding, to process need make earlier usually and expect extrusion molding two procedures again, production efficiency is lower.
The purpose of utility model just is to solve the shortcoming of above-mentioned prior art, provide a kind of and can obtain bigger geometrical compression ratio, can bear bigger moment of torsion, screw rod and machine barrel adjustable gaps are whole, be widely used, the production efficiency height, and simple in structure, the taper single-screw extruder of more convenient operation.
The technical solution of the utility model is achieved in that a kind of taper single-screw extruder, its screw rod cylindrical is a coned face, the machine barrel endoporus supporting with it is bellmouth, feeding section screw rod and diameter of bore are greater than metering section screw rod and diameter of bore, screw rod feeding section end is provided with one and adjusts pad, and machine barrel feeding section end is provided with thrust box.
This utility model project organization advantages of simple, easy to operate, applied range can be enhanced productivity greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structure chart of the present utility model;
As shown in the figure, this machine is made of conical screw 1, machine barrel 2, machine barrel attemperating unit 3, hopper 4, thrust box 5, reduction box 6, drive motors 7, frame 8, Electric Appliance Cabinet 9, adjustment pad 10, support 11 etc.
At first adjust thrust box 5 and the relative position of machine barrel 2 and the thickness of change adjustment pad 10 according to the material variety size, adjust the gap length of conical screw 1 and machine barrel 2, under the driving of drive motors 7, conical screw 1 begins rotation by the speed change transmission of reduction box 6 then.Plastic raw materials is pushed to heading gradually along with the rotation of conical screw 1 after entering machine barrel 2 by hopper 4.At feeding section, screw channel is full of by loose solids (or powder) shape material, and beginning is compacted gradually.After material enters the compression section, because screw channel shoals gradually and the resistance of head, in material, formed very high pressure, press material very closely knitly, simultaneously under the effect of the mixing of outer heat that machine barrel attemperating unit 3 is transmitted and conical screw 1,2 pairs of materials of machine barrel, interior frictional heat that shear action produced, the temperature of plastics raises gradually.After reaching flow temperature with contacted certain any the temperature of charge of machine barrel 2 walls, plastic raw materials begins fusion gradually.Along with being fed forward of material, the inventory of fusion increases gradually, and the inventory of fusion does not reduce gradually, greatly about the end of compression section, and all material fusions and change viscous state into.Pass through the homogenization of homogenizing zone again, last conical screw 1 with fused materials quantitatively, level pressure, clamp-on head constant temperature.A mouthful mould is a fashion-part in the head, and material just obtains the geometry and the size of a uniform section by it, passes through cooling and shaping and other operation again, just can obtain the goods of forming.
Claims (2)
1. taper single-screw extruder, form by reduction box (6), drive motors (7), frame (8), machine barrel attemperating unit (3), hopper (4), Electric Appliance Cabinet (9), it is characterized in that: the periphery of screw rod (1) is a coned face, the machine barrel supporting with it (2) endoporus is a bellmouth, holds feeding section screw rod and diameter of bore greater than discharge port end metering section screw rod and diameter of bore near hopper (4).
