Abstract
The utility model discloses a support device for an extruder screw comprising an external ring body, an inner ring body, a connecting bar arranged between the inner ring body and the outer ring body and a circular bearing or circular bushing sleeved on the inner ring body. The utility model is characterized in that the stability of an extruder screw can be kept by the support device and the clearance between inner sleeve on a combining barrel in circle direction is uniform, thus no wearing occurs because of floating. The utility model has the advantages of improved service life for the screw and the barrel, reduced production cost, improved extruder productivity, yield and product quantity.
Description
Technical field:
The utility model relates to a kind of bracing or strutting arrangement, especially relates 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, make reduce the service life of screw rod and barrel liner, the replacing frequency strengthens, particularly the screw extruder of big specification.
The utility model content:
The purpose of this utility model 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 unsteady extruder screw that produces of extruder screw and the wear phenomenon between the machine barrel can not appear.
The purpose of this utility model 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, be with annular bearing or bearing shell in described on the torus.
The interior ring of described annular bearing or annular bearing shell matches with the outside of the support zone of described screw rod, and promptly 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.
Advantage of the present utility model is: the bracing or strutting arrangement of extruder screw can make screw rod keep stable, even with the circumferencial direction gap that cooperates barrel liner, unsteady extruder screw that produces of extruder screw and the wear phenomenon between the machine barrel have been changed, the use of this device makes original wear phenomenon change into support zone and the annular bearing of the utility model bracing or strutting arrangement or the wearing and tearing between the annular bearing shell of extruder screw, only need periodic replacement bearing or bearing shell, improved the service life of screw rod and machine barrel greatly, reduced production cost, improve the production efficiency of extruder, improved the quality of output and extruded product.

Fig. 3 is the utility model extruder screw 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:
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, be with annular bearing 4 on interior torus 2, 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 promptly 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 bracing or strutting arrangement that the utility model extruder screw is installed and the related data content that the bracing or strutting arrangement of the utility model extruder screw 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 the utility model extruder screw is not installed, and influenced 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 the utility model extruder screw has been installed, and influenced 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 kilograms/hour.
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: as can be known by above-mentioned experimental data, the screw rod, the service life of machine barrel of XJD-250 pin cold feed extruder that the bracing or strutting arrangement of the utility model extruder screw 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%, and the power consumption of the unit's of making sizing material has descended 33.3%.
