Abstract
The invention discloses a rotating cylinder of a single-screw extruder with a thread, and relates to a mechanical component. The cylinder comprises single screw (2), and a rotating cylinder (1) with the thread, wherein the thread is arranged at the inner side of the cylinder; and the rotating direction of the thread at the inner side of the cylinder is opposite to the rotating direction of the thread of the fitting single screw. A rotating bearing for the cylinder is fixed on a body of the extruder. The screw and the rotating cylinder with the thread can be combined to build pressure in an extrusion direction. The screw and the cylinder are rotated oppositely, so that the relative speed of a material is quickened, and the shearing capacity is enhanced. The pressure building capacity, the mixing capacity, the shearing capacity and the extruding capacity of the extruder can be largely improved.
Description
Technical field
The present invention relates to a kind of mechanical component, particularly relate to a kind of extruder cylinder of single screw extruder with screw thread rotation.
Background technology
In extruder, most important core technology is screw flight shape and screw rod and the coordinating of machine barrel, common extruder cylinder of single screw extruder is smooth and fixing, people are devoted to study the impact of screw thread form on extruder performance, and this is restricted the raising of single screw extrusion machine performance.
Summary of the invention
The object of the present invention is to provide a kind of extruder cylinder of single screw extruder with screw thread rotation, this machine barrel is rotatable and be threaded, and is conducive to increase extrude directional pressure, increases shearing force, the motion of generation whirlpool, extrusion performance and the scattered mixed performance of raising extruder.
The object of the invention is to be achieved through the following technical solutions:
An extruder cylinder of single screw extruder with screw thread rotation, described machine barrel comprises single screw rod, and the threaded rotation machine barrel of tool, and machine barrel inner side is threaded, and the thread rotary orientation of machine barrel inner side is contrary with single screw flight rotation direction that cooperatively interacts.
Described a kind of extruder cylinder of single screw extruder with screw thread rotation, described machine barrel is fixed on extruder fuselage with rolling bearing.
Advantage of the present invention and effect are:
Screw rod of the present invention and screwed rotation machine barrel are built pressure jointly extruding the direction first line of a couplet.Screw rod and machine barrel counter-rotate, and have increased the relative velocity of material, and shear ability is increased.Can increase substantially upbuild voltage capacity, mixing ability, shear ability and the plasticating capacity of extruder.
Brief description of the drawings
Fig. 1 is the constitutional diagram of machine barrel of the present invention and screw rod;
Fig. 2 is list screw rod figure of the present invention;
Fig. 3 is the threaded rotating machine sketch drawing of the present invention;
Fig. 4 is list screw rod of the present invention and the threaded rotation machine barrel of tool intermediate cross-section schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
The present invention includes single screw rod 2, the threaded rotation machine barrel 1 of tool.Screw rod 2 is contrary with the thread rotary orientation of machine barrel 1, and direction of rotation is conducive to increase and extrudes directional pressure, increases shearing force, produces whirlpool motion.Be conducive to extrusion performance and the scattered mixed performance of single screw extrusion machine.Rotation direction is oppositely contrary with the rotation of single screw rod, and speed coordinates arbitrarily, finds optimum performance.Machine barrel inner side is threaded.The thread rotary orientation of machine barrel inner side is contrary with the single screw flight rotation direction cooperatively interacting.
Embodiment 1:
The screw thread of machine barrel 1 contrary with the hand of spiral of screw rod 2 (right-hand screw and left-hand screw), their rotation direction is also contrary.Screw rod 1 can have different cooperation speed from machine barrel 2.Screw rod and screwed rotation machine barrel are built pressure jointly extruding the direction first line of a couplet like this, are conducive to improve the extrusion performance of extruder.Screw rod and 1 machine barrel 2 counter-rotate, and have increased the relative velocity of material, and shear ability is increased, and are conducive to the abundant mixing of material in machine barrel.Machine barrel 1 can be fixed on extruder fuselage with 2-3 rolling bearings.Machine barrel 1 has contrary screw thread with screw rod 2.Machine barrel 1 has contrary turning to screw rod 2.Machine barrel can coordinate arbitrarily with the rotating speed of screw rod, to find best of breed.
Threaded tool rotation machine barrel 1 is fixed on extruder fuselage with rolling bearing, can be with the rotating speed of driving-belt control machine barrel, machine barrel 1 cooperatively interacts with screw rod 2, and rightabout rotates, and machine barrel 1 and screw rod 2 have the screw thread of different rotation directions.The speed of machine barrel and the speed of screw rod are selected to find best of breed arbitrarily.In the time of System Operation, screw rod 2 and machine barrel 1 can produce the pressure of extruding direction, and pressure superposition improves upbuild voltage capacity.Screw rod 2 counter-rotates with machine barrel 1, has increased the relative velocity of material, and shear ability is increased, and improves the mixing ability of extruder.
Claims (2)
1. one kind has the extruder cylinder of single screw extruder of screw thread rotation, it is characterized in that, described machine barrel comprises single screw rod (2), and the threaded rotation machine barrel of tool (1), machine barrel inner side is threaded, and the thread rotary orientation of machine barrel inner side is contrary with single screw flight rotation direction that cooperatively interacts.
2. a kind of extruder cylinder of single screw extruder with screw thread rotation according to claim 1, is characterized in that, described machine barrel is fixed on extruder fuselage with rolling bearing.
