Problems solved by technology

[0004] When the existing single-screw extruder extrudes the powder, the surface renewal of the powder is small, the powder stays in the single-screw extruder for a long time, and the powder is easy to adhere to the screw groove, so that the powder The mixing effect is poor, which is not conducive to the uniform dispersion of the components in the powder

Abstract

The application relates to a single-screw extruder comprising a machine body, and a driving device is arranged on the machine body; a machine barrel is fixedly arranged on the machine body, and a rotating barrel is coaxially arranged in the machine barrel; a screw rod is coaxially arranged in the rotating barrel, and first threads are fixedly arranged on the screw rod, and both the rotating barreland the screw rod are rotatably connected with the machine body; second threads are fixedly arranged on the inner wall of the rotating barrel, and the first threads and the second threads are the same in rotating direction and thread pitch, and are arranged in a staggered mode; and a feeding hopper is fixedly arranged on the machine cylinder, and communicates with the interior of the rotating barrel. The single-screw extruder has the effect of improving the mixing effect of the single-screw extruder.

Description

technical field [0001] The present application relates to the field of extruders, in particular to a single-screw extruder. Background technique [0002] Screw extruder is a kind of automatic feeding equipment. Commonly used screw extruders include single-screw extruder and twin-screw extruder. [0003] The extrusion process of the single-screw extruder mainly relies on the friction difference between the material and the inner wall of the barrel and the surface of the screw to push the material forward along the screw groove, and is mostly used for extrusion processing of pellets; while in the twin-screw extruder , especially the meshing twin-screw extruder, the material transmission is to some extent positive displacement transmission, which is often used in powder processing. [0004] When the existing single-screw extruder extrudes the powder, the surface renewal of the powder is small, the powder stays in the single-screw extruder for a long time, and the powder is eas...
