Problems solved by technology

When the traditional extruder screw is in use, the screw is floating. With the flow of the rubber in the screw groove, the screw floats up and down, and the barrel is easily worn, or even severely worn, so that the use of the screw and the inner sleeve of the barrel Reduced lifespan and increased replacement frequency, especially for larger screw extruders

Embodiment approach

[0013] Such as figure 1 , figure 2 , image 3 As shown, a support device for an extruder screw includes an outer ring body 1, an inner ring body 2, a connecting rib 3 is provided between the inner and outer ring bodies 1 and 2, and the inner ring body 2 Ring bearing 4 is sleeved on, also can be ring bearing bush 4. There are at least two connecting ribs 3, and there may be three, four or more. The inner ring of the ring bearing 4 or the ring bearing bush 4 cooperates with the outside of the supporting part of the screw rod 5 , that is, the supporting end of the screw rod 5 is located in the inner cavity of the ring bearing 4 or the ring bearing bush 4 . The outer side of the outer ring body 1 cooperates with the inner ring of the machine barrel 6 .

[0014] The relevant data content of the support device installed with the extruder screw of the present invention and the support device without the extruder screw of the present invention will be compared below in conjunctio...

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: [0001] The invention relates to a support device, in particular to a support device for the extruder screw. Background technique: [0002] The gap between the extruder screw and the matched extruder barrel needs to maintain a certain allowable value. When it exceeds a certain allowable value, it must be replaced in time, otherwise the output will be affected. When the traditional extruder screw is in use, the screw is floating. With the flow of the rubber in the screw groove, the screw floats up and down, and the barrel is easily worn, or even severely worn, so that the use of the screw and the inner sleeve of the barrel The service life is reduced and the frequency of replacement is increased, especially for larger size screw extruders. Invention content: [0003] The purpose of the present invention is to provide a screw that can keep the screw stable, and the circumferential gap between the inner sleeve of the matching machine barrel is even, and there...
