Description
Technical field
The utility model relates to a kind of plastic machinery equipment, particularly a kind of screw arbor assembly of extruder.
Background technology
The working mechanism of screw-type extruder relies on screw rod to rotate the pressure and shearing force that produce, and material can be made fully to carry out plastifying and Homogeneous phase mixing.Screw rod is the heart of extruder, is the critical component of extruder, and the performance quality of screw rod, determines the productivity ratio of an extruder, plasticizing quality etc.It is the most important parts of extruder, and it directly can have influence on range of application and the production efficiency of extruder.At present, double screw extruder uses screw screw rod and driving shaft to be fixed usually, and after extruder uses for a long time, screw easily loosens, and causes screw rod to produce displacement, the spacing of the blade of screw rod is changed, blade may be caused to collide with each other; In addition, the screw arbor assembly assembling of prior art is time-consuming, is not easy to demolition and maintenance.
Utility model content
The utility model, in order to solve the problem of prior art, provides one and is convenient to assembling and safeguards, and the screw arbor assembly of the extruder that blade can be avoided to collide with each other.
Concrete technical scheme is as follows: a kind of screw arbor assembly of extruder, comprise screw rod, driving shaft and jockey, jockey respectively with screw rod, driving shaft connects, described jockey comprises linkage section, keeper and adaptor ring, linkage section is connected with screw rod, linkage section has concave part, concave part inside is provided with screw, the mating part of screw and driving shaft connects, driving shaft has cannelure, cannelure is exposed to the concave part of linkage section, described keeper is arranged in cannelure, the first end of keeper is resisted against the side end of concave part, described adaptor ring has through hole, through hole to be set in outside mating part and collecting keeper, through hole one end has threaded portion, internal thread in threaded portion is threaded with concave part.
It is below attached technical scheme of the present utility model.
Preferably, described keeper comprises two buckles, and the cross section of buckle is semicircle, and buckle is arranged in the cannelure of driving shaft.
Preferably, the inside of described threaded portion has stopper, and the second end of keeper is resisted against stopper.
Preferably, described linkage section has segregation section, segregation section and groove part every the outer end of, segregation section and screw rod for be removably connected.
Technique effect of the present utility model: the screw arbor assembly of extruder of the present utility model can avoid screw rod to produce displacement after a long time use, prevents the collision between blade, thus improve life-span and production efficiency; In addition, it is convenient to assembly and disassembly, effectively improves assembling and maintenance efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 6, the screw arbor assembly of the extruder of the present embodiment comprises screw rod 1, driving shaft 2 and jockey 3, and jockey 3 is connected with screw rod 1, driving shaft 2 respectively, thus driving shaft 2 can be moved by drive screw 1.Described jockey 3 comprises linkage section 31, and keeper 32 and adaptor ring 33, linkage section 31 is connected with screw rod 1.Linkage section 31 has concave part 311, and concave part 311 inside is provided with screw 312, and screw 312 connects with the mating part 21 of driving shaft.Driving shaft 2 has cannelure 22, and cannelure 22 is exposed to the concave part 311 of linkage section.Described keeper 32 is arranged in cannelure 22, and the first end of keeper 32 is resisted against the side end of concave part 311.Described adaptor ring 33 has through hole 331, and through hole 331 is set in the outer and collecting keeper 32 in mating part 21, and through hole 331 one end has threaded portion 332, and the internal thread in threaded portion 332 is threaded with concave part.Technique scheme is when the screw rod of extruder and driving shaft rotate, and adaptor ring and linkage section can not produce loosening, and screw rod can not produce displacement, and the spacing of the blade 12 of two screw rods can not change, thus avoids producing collision between blade; In addition, technique scheme is convenient to assembly and disassembly, thus is conducive to improving assembling and maintenance efficiency.
As shown in Figures 1 to 6, further, described keeper 32 comprises two buckles 321, and the cross section of buckle 321 is semicircle, and buckle 321 is arranged in the cannelure 22 of driving shaft, thus is convenient to manufacture and the installation of buckle.The inside of described threaded portion 332 has stopper 333, and the second end of keeper 32 is resisted against stopper 333, thus the location enabling keeper firm.Described linkage section 31 has segregation section 312, and segregation section 312 and concave part 311 are separated, and segregation section 312 is detachable with the outer end 11 of screw rod.Extruder 100 comprises body 10, gear-box 20 and barrel 30, and screw arbor assembly 40 is arranged in barrel 30, and screw arbor assembly comprises two screw rods be arranged in parallel 1, and the extruder of the present embodiment is double screw extruder.The periphery of screw rod 1 is provided with blade 12, and the plastics being fallen into barrel 30 by feed opening 50 are promoted by the extruding of blade 12, are discharged by discharging opening.
The screw arbor assembly of the extruder of the present embodiment can avoid screw rod to produce displacement after a long time use, prevents the collision between blade, thus improves life-span and production efficiency; In addition, it is convenient to assembly and disassembly, effectively improves assembling and maintenance efficiency.
It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
