Description

Technical Field

[0001] The utility model relates to the technical field of extruder discharge adjustment, and more specifically, to a high-speed co-directional extruder discharge amount adjustment device. Background Art

[0002] PVC high-speed co-rotating extruder is a kind of equipment used to process PVC (polyvinyl chloride) raw materials. It is usually widely used in the production of PVC pipes, plates, films, profiles and other products. When the PVC high-speed co-rotating extruder is working, first, the resin powder, benzene, calcium powder and other raw materials need to be mixed in proportion and fed into the feed port of the co-rotating extruder. Inside the extruder, the PVC raw materials are heated to become an extrudable molten state, and then the screw is used for extrusion and stirring. The PVC pellets are extruded through the die head in the required shape and size. The extruded PVC finished particles are quickly cooled and solidified in the cooling area. Finally, they are collected and packaged by conveyor belts or other collection devices to obtain PVC cable materials.

[0003] However, usually, the discharge port of the existing extruder is relatively fixed and cannot be adjusted. If the extruder is used to produce pellets of different sizes, it may be necessary to replace the mold to adjust the discharge port. As a result, when the discharge port of the extruder needs to be adjusted according to product production requirements, the staff needs to use professional tools and spend a long time to remove and replace the outlet, resulting in long downtime and reduced overall production efficiency.

[0014] In the above scheme, by setting up a feeding component, the operator puts the production raw materials into the hopper, and then starts the motor to rotate the spiral plate connected to the output end of the motor. As the spiral plate rotates, the raw materials falling on the surface of the spiral plate flow into the interior of the extruder body through the connecting pipe. Through the above structure, the speed at which the raw materials flow into the interior of the extruder body can be controlled to avoid a large amount of raw materials falling directly into the interior of the extruder body, resulting in the inability to fully heat the raw materials, affecting the subsequent extrusion effect and production quality.
