Description

Technical Field

[0001] The utility model relates to the technical field of extruders, and more specifically to an anti-blocking high-speed co-directional extruder. Background Art

[0002] High-speed co-rotating extruder is a kind of mechanical equipment commonly used in plastic processing. It is a special type of extruder, which is mainly used to form the molten plastic into the desired shape through extrusion and pressure. The working process of the extruder is usually to put the raw materials into the hopper first, and the plastic raw materials in the hopper are transported into the extruder barrel. At this time, the plastic raw materials will gradually heat, melt and mix. The molten plastic raw materials are pushed into the extrusion mold by the screw. The rotation and pressure control of the screw make the plastic extruded from the opening of the mold to form the desired cross-section and shape.

[0003] Since the surface of plastic granular raw materials has a certain adhesion, when a large amount of granular raw materials are put into the hopper and piled together, the friction between the particles will increase, which will increase the resistance of the material moving in the hopper, making it impossible for the material to flow freely, resulting in blockage, and ultimately leading to negative effects such as reduced production quality and extended production plans.

The rotation of the propulsion dragon will evenly feed the raw material into the heating extrusion device for extrusion operation. Utilizing the above structure, the effect of improving production quality and reducing work delays caused by blockage is achieved.

[0015] In the above scheme, the hot air blower is turned on to suck in and heat the external air, and then the heated air is transported to the annular air outlet pipe through a connecting pipe and ejected, so as to evenly heat the raw material particles inside the feed hopper.
