Extruder normal production and operation, and sometimes encountered a sudden power failure or barrel into the metal block foreign body, so that the screw suddenly stop the rotation of the fault, this time the treatment is as follows.
① immediately turn off the motor, electric heating and feeding system switch, the control knob to open or return to zero.
② If the barrel is PVC raw material, should immediately cool the barrel; immediately remove the mold, exit the screw; remove the mold parts and screws, barrel on the sticky material, to be troubleshooting and then install the screw and forming mold; Re-for the barrel, forming mold heating temperature, to the temperature and then the temperature after 1h production.
③ If the barrel is polyethylene or polypropylene raw materials, encountered a sudden power failure, as long as the switch off, the speed control knob back to zero, waiting for calls. When driving the car to produce the order: the barrel and the mold began to heat up the temperature, to achieve the required temperature of the process heating temperature of more than 2h (the barrel temperature within the material, with the hand to pull the V pulley can be more easily rotated) And then start the lubricating oil pump, work 3min and then start the screw rotation work, ... ..., according to the original car production order.
