Abstract
The invention discloses a universal tapered co-directional double-screw-rod extruder for plastic pipes and sheets. The universal tapered co-directional double-screw-rod extruder comprises a driving motor, a deceleration distribution box system, a feeding system, a transmission system, a tapered co-directional double-screw-rod system, an extruder barrel system and an exhaust system; and the tapered co-directional double-screw-rod system comprises a main tapered screw rod and an auxiliary tapered screw rod, the rotating directions of the main tapered screw rod and the auxiliary tapered screw rod are co-directional, and the main tapered screw rod and the auxiliary tapered screw rod are sequentially provided with feeding zones, plasticizing zones, reverse thread zones, secondary plasticizing zones, separation zones, exhaust zones and extrusion zones along the moving direction of materials. The tapered co-directional double-screw-rod extruder has the advantages that shearing heat is large, plastication is good, mixing is good, the filling ratio is high, product strength is good, the surface is bright, no discharge from an exhaust port occurs, transmission torque of the deceleration distribution box system is large, the bearing capacity is doubled, the service life is prolonged greatly, noise is small, and manufacturing is simple; according to the universal tapered co-directional double-screw-rod extruder for the plastic pipes and the sheets, and not only can the plastic sheets be extruded, but also the plastic pipes can be extruded.
Description
technical field [0001] The invention relates to the field of plastic extrusion, in particular to a conical co-rotating twin-screw extruder. Background technique [0002] At present, the equipment used in the manufacture of plastic pipes and plastic sheets mainly includes single-screw extruders, conical counter-rotating twin-screw extruders and conical co-rotating twin-screw extruders. The only advantage of single-screw extruder is low cost, but there are defects in extrusion force, plasticizing performance and energy consumption. The advantages of conical counter-rotating twin-screw extruders are large extrusion force, but poor plasticizing performance, low output, and high energy consumption. Conical co-rotating twin-screw extruder, because the conical screw rotates in the same direction, the plastic to be processed enters the barrel and is extruded in a figure-eight shape around the conical twin-screw in the barrel, which increases the plasticizing time and reduces The f...
