Abstract
The utility model provides an extruder screw rod installation mechanism, including connector, feed cylinder, two input shafts, the connector is fixed and the intercommunication with the feed cylinder, and the connector is equipped with the intercommunication mouth with the junction of feed cylinder, the input shaft stretches into the connector, is connected with first integral key shaft on the input shaft, be equipped with two screw rods in the feed cylinder, be equipped with the second integral key shaft in the screw rod, the second integral key shaft aligns with first integral key shaft in stretching into the connector, first integral key shaft has the spline housing with the outside cover of second integral key shaft, this installation mechanism's screw rod and input shaft pass through to be connected between the integral key shaft, and on being fixed in the connecting axle through the pin, simplify mounting structure, installation stability simultaneously is high, and simultaneously, owing to rationally controlled the clearance between screw rod and the feed cylinder inner wall, what adopt is the twin -screw form in addition, glue the phenomenon of covering so avoided plastics and screw rod surface effectively, because the structure is handled for mirror finish in the screw rod surface, so the operation is more steady, output is high, the energy consumption is low simultaneously.
Description
Technical field
This utility model relates to extruder equipment part field, particularly relates to a kind of extruder screw installing mechanism.
Background technology
Screw extruder be dependent on screw rod rotate produce pressure and shearing force, can make material can sufficiently conducted plasticizing and Homogeneous phase mixing, by mouth die molding, one of plastic extruder kind falling within plastics machinery.Extruder is according to the angle of Head material flow path direction and pitch line, it is possible to head is divided into right-angle handpiece and bevelling machine is first-class.The shell of head is usually and is secured on fuselage with bolt, mould inside head contains core rod seat, is then fixed in the inlet wire port of head with nut, and the inside of core rod seat is also equipped with core rod, and the center of core rod and core rod seat is all porose, it is used for passing through heart yearn.Difference according to pressuring method kind so that expressing technique is segmented into continuously extrusion and interval extrusion two kinds.The former equipment used is screw-type extruder, and the equipment of the latter is plunger-type extruder.
In screw-type extruder, moment that usual screw rod is required in extrusion and rotating speed, traditional syllogic connected mode can make to install between screw rod and power shaft instability, and also there is the phenomenon that plastics cover with screw surface, it is common to exists and yields poorly, plastic pellet surface defect (trace, aperture, crafters, surface is crude), extruder is short for service life, causes the problems such as energy consumption is high that yield poorly.
Utility model content
For solving above-mentioned technical problem, the utility model proposes a kind of extruder screw installing mechanism, including connector, barrel, two power shafts, described connector is fixed with described barrel and connects, and the junction of described connector and described barrel is communicated with mouth；Described power shaft stretches into described connector, and described power shaft is connected to the first splined shaft；Being provided with two screw rods in described barrel, be provided with the second splined shaft in described screw rod, described second splined shaft stretches in described connector and aligns with described first splined shaft, is cased with spline housing outside described first splined shaft and described second splined shaft.
Preferably, being provided with stop collar in the connected entrance of described connector, running through in described stop collar has pin, and described pin is fixed on described stop collar inwall through described second splined shaft and spline housing.
Preferably, described barrel and described connector are fixed by screw.
Preferably, described connector is hollow cuboid.
Preferably, described connector top is provided with figure of eight through hole, two described power shaft described figure of eight through holes of traverse.
Preferably, the gap between described screw rod and described barrel is 0.1mm-0.14mm.
The extruder screw installing mechanism that the utility model proposes has following beneficial effect: 1, screw rod is connected by between splined shaft with power shaft, and it is fixed on connection axle by pin, simplify mounting structure, mounting stability is high simultaneously, 2, the gap between screw rod and material tube inner wall due to conservative control, what adopt is twin screw form in addition, so efficiently avoid the phenomenon that plastics cover with screw surface；Processing structure simultaneously because screw surface is mirror finish, therefore run more steady, yield is high, and energy consumption is low.
