The raw material is added into the hopper, and through the shear force and propulsion force generated by the screw rotation, the material is gradually plasticized and melted in the barrel to form a uniform melt. Then, the melt is pushed by the screw through the extrusion mold, the shape of the extrusion mold determines the cross-section shape and size of the pipe, the extruded pipe is cooled and shaped by the cooling and shaping device, and finally, it is hauled by the haul-off device for continuous output, which completes the continuous extrusion of the pipe production.
Working Principle:
The raw material is added into the hopper, and through the shear force and propulsion force generated by the screw rotation, the material is gradually plasticized and melted in the barrel to form a uniform melt. Then, the melt is pushed by the screw through the extrusion mold, the shape of the extrusion mold determines the cross-section shape and size of the pipe, the extruded pipe is cooled and shaped by the cooling and shaping device, and finally, it is hauled by the haul-off device for continuous output, which completes the continuous extrusion of the pipe production.
Features:
Compact size: Compared with the large pipe extruder, it occupies a small area, is more flexible and convenient to install and use, and is suitable for small production workshops or laboratories and other places with limited space.
Continuous production: it can realize continuous extrusion of pipes with high production efficiency, which can meet the production demand of a certain scale.
Easy to operate: the control system is relatively simple, the operator can master the operation method after simple training, easy to start.
Structure Composition：
Extrusion system: It is the core part, mainly composed of hopper, screw, barrel and so on. The screw part can be customized according to the material and demand.
Transmission system: provides power for the screw of the extrusion system, usually composed of motor, reducer, etc., to ensure that the screw rotates at a stable speed to ensure the continuity and stability of the extrusion process.
Heating and cooling system: used to heat and cool the barrel and mold. The heating method generally adopts electric heating, and the barrel is heated evenly through the heating ring, so that the material can be plasticized and melted under the appropriate temperature; the cooling system is mainly used to cool the extruded pipe, so that it can be shaped quickly, and the commonly used cooling methods include air cooling and water cooling.
Die system: determines the shape and size of the pipe, according to the material and the demand for finished products customized die.
Haul-off device: Used to haul off the extruded pipe so that the pipe can be continuously output at a stable speed to ensure the smooth running of the extrusion process.
Cutting device: The continuously extruded pipe is cut according to a certain length to facilitate subsequent packaging and use. There are various cutting methods of the cutting device, such as sawing, hot cutting, etc., and the suitable cutting method can be selected according to the material of the pipe and production requirements.
