Pb Pipe Extrusion Line

High speed PB extruder adopts notched barrel with water forced cooling transportation zone and shielded screw with special mixing structure for PB, ensuring extrusion stability and good quality of plasticization. Specially structured spiral accumulator type die head surmounts stress orientation of polymer chain during forming pipe and achieve a constant pressure pipe extrusion. High-speed low-temperature extrusion of raw materials to make PB an excellent physical and chemical properties of an exact copy to the pipe at the same time, the stability of the extrusion pressure is to achieve a strong guarantee for high-speed production; Vacuum calibrating mandrel adopts mult-sheet water immersion calibrating mandrel (invention, realized the cooling calibrating evenly and effectively for plastic pipe, ensuring high speed production of the pipe. High speed flat belt pulling machine with multi-group roll wheel adopts originally imported frequency inverter, making pulling of high speed steady and reliable, thoroughly subverting the vibration and slipping during high speed pulling in the traditional mode of rubber blocks pipe machine; Adopting the newest type and high speed cutting machine, it realizes instantaneous cutting during high speed processing of small calibrating mandrel with no-deformation and dustless of pipe section; The entire production line adopts the originally imported new control system of PLC programmable computer, guaranteed highly and steadily reliable controls of the whole production line
