Components of PE pipe production lineComponents of PE pipe production line
The pe pipe production line includes: feeding system, single screw extruder, special mold for PE pipe, sizing, cooling system, tractor, ticket collector, and control system. The extruder is one of the important core components of the pipe extrusion line, and the main machine used in pipe processing is a single screw extruder. In the planning of a single screw extruder, how to achieve high-speed extrusion of pipes at low processing temperatures is a key technology.
In the screw planning, the combination of BM structure and barrier structure is selected, and a special mixing section is added, which not only ensures the plasticizing effect of the tube blank, but also the material is in various areas on the entire screw, and the melt pressure is lower. , The pressure is evenly distributed, and the shearing effect is strictly controlled together to obtain the ideal material temperature.

In the barrel planning, a slotted barrel is selected, and a feeding bushing with a structure is specially planned. The inner hole is equipped with multiple inclined grooves to ensure high-speed feeding of PE. There is a special plan in the feeding section. Cooling equipment to complete the temperature control of the barrel feeding area and isolate it from the adjacent barrel high temperature area. Each section of the barrel has a temperature-controllable heating section, and forced air cooling is used. The output value of the extruder has an outstanding linear relationship (to facilitate simultaneous adjustment with the traction speed). In order to complete high-speed extrusion, the gearbox is selected with high torque and low noise. The gearbox and motor power are matched accordingly.
