Abstract
The extruder screw supporting device includes one outer ring, one inner ring, connecting ribs set between the outer ring and the inner ring, and one ring bearing or bearing bush on the inner ring. The extruder screw supporting device can maintain the stability of the screw, make the circumferential gap between the screw and the inner machine sleeve homogeneous and avoid the wear caused by floating. The present invention can increase the service life of the screw and the inner machine sleeve, lower the production cost, and raise the production efficiency of the extruder and the extruded product quality.
Description
Technical field:
The present invention relates to a kind of bracing or strutting arrangement, especially relate to a kind of bracing or strutting arrangement of extruder screw.
Background technology:
Gap between the extruder barrel that extruder screw is mated need keep certain permissible value, when surpassing certain permissible value, must in time change, otherwise can have influence on output.Traditional extruder screw in use, screw rod is floating type, along with flowing of sizing material in the screw slot, screw rod fluctuates, very easily produce wearing and tearing with machine barrel, even heavy wear, so that reduce the service life of screw rod and barrel liner, replacement frequency strengthens, particularly the screw extruder of larger specification.
Summary of the invention:
The object of the present invention is to provide a kind of screw rod that can make to keep stable, even with the circumferencial direction gap that cooperates barrel liner, the bracing or strutting arrangement because of the extruder screw of the unsteady extruder screw that produces of extruder screw and the wear phenomenon between the machine barrel can not appear.
Purpose of the present invention is implemented by following technical scheme: a kind of bracing or strutting arrangement of extruder screw includes the cylindrical ring body, and interior torus is provided with dowel between described inside and outside torus, at described interior torus cover annular bearing or bearing shell is arranged.
The interior ring of described annular bearing or annular bearing shell matches with the outside of the support zone of described screw rod, and namely the support end of screw rod is positioned in the inner chamber of described annular bearing or annular bearing shell.
Match with the interior ring of described machine barrel in the outside of described outer toroid.
The invention has the advantages that: the bracing or strutting arrangement of extruder screw can make screw rod keep stable, even with the circumferencial direction gap that cooperates barrel liner, the unsteady extruder screw that produces of extruder screw and the wear phenomenon between the machine barrel have been changed, the use of this device is so that original wear phenomenon changes into support zone and the annular bearing of bracing or strutting arrangement of the present invention or the wearing and tearing between the annular bearing shell of extruder screw, only need periodic replacement bearing or bearing shell, greatly improved the service life of screw rod and machine barrel, reduced production cost, improve the production efficiency of extruder, improved the quality of output and extruded product.
Description of drawings:
Fig. 1 is the main cutaway view of looking of the present invention.
Fig. 2 is side view of the present invention.
Fig. 3 is the extruder screw of the present invention structural representation that matches with the extruder screw bracing or strutting arrangement.
Cylindrical ring body-1, interior torus-2, dowel-3, annular bearing-4, screw rod-5, machine barrel-6.
Embodiment:
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of bracing or strutting arrangement of extruder screw includes cylindrical ring body 1, and interior torus 2 is provided with dowel 3 between inside and outside torus 1 and 2, at interior torus 2 covers annular bearing 4 is arranged, and also can be annular bearing shell 4.Dowel 3 is at least two, also can be three, and four etc. a plurality of.The interior ring of annular bearing 4 or annular bearing shell 4 matches with the outside of the support zone of screw rod 5, and namely the support end of screw rod 5 is positioned in the inner chamber of annular bearing 4 or annular bearing shell 4.The outside of cylindrical ring body 1 cooperates with the interior ring of machine barrel 6.
Contrast the bracing or strutting arrangement that extruder screw of the present invention is installed and the related data content that the bracing or strutting arrangement of extruder screw of the present invention is not installed below in conjunction with embodiment.
Control group: the screw rod, the service life of machine barrel of XJD-250 pin cold feed extruder of the bracing or strutting arrangement of extruder screw of the present invention is not installed, and affected the parameter of extruder performance.
Experimental group: the screw rod, the service life of machine barrel of XJD-250 pin cold feed extruder of the bracing or strutting arrangement of extruder screw of the present invention has been installed, and affected the parameter of extruder performance.
The highest extruded velocity of annotating the 1:XJD-250 pin cold feed extruder is 26r/min.
The maximum production of annotating the 2:XJD-250 pin cold feed extruder is 3600 kg/hrs.
Annotate 3: the power consumption=power of unit sizing material/output.
Annotate 4: XJD-250 pin cold feed extruder power is constant in the table.
Sum up: by above-mentioned experimental data as can be known, the screw rod, the service life of machine barrel of XJD-250 pin cold feed extruder that the bracing or strutting arrangement of extruder screw of the present invention has been installed all rises appreciably, about 3 months replacing bearings or bearing shell once, the approximately annual cost of changing is 800 yuan greatly.
Show by data simultaneously, the XJD-250 pin cold feed extruder of the bracing or strutting arrangement of extruder screw has been installed, its extruded velocity improves 30% than the speed of the XJD-250 pin cold feed extruder of the bracing or strutting arrangement that extruder screw is not installed is the highest, because the extruded velocity of extruder has improved, its output also can increase by 30%, so that the power consumption of unit sizing material has descended 33.3%.
