Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a feed pipe supporting structure of a screw extruder. Background Art

[0002] A screw extruder is an automatic feeding device, which is divided into two types: cold feed screw extruder and hot feed screw extruder. Both are used to extrude rubber semi-finished products and finished products. The hot feed screw extruder must be fed with heat-refined rubber material, which is further plasticized through the effects of screw extrusion, shearing and stirring, and is continuously extruded in an n-shaped manner. The feed end of the existing screw extruder is directly connected to a screw extruder by a feed pipe. The material flow rate is too large, and when multiple screw extruders are used simultaneously, the feed pipe does not have any fixed support, which makes the material noisy during transportation and causes vibration of the feed pipe, thereby causing the connection between the feed pipe and the screw extruder to separate after a period of use, resulting in insufficient overall safety.
