The plastic pipes extrudeddeparts from the machine head and enters traction machine through vacuumshaping cooling box, and are held by the traction machine to carry out the tractionof pipe products, and are sent to cutter, stationary length incision, filletand stacking.Center height of machine is according with the center height of calibration tank,and it is pressure equalization. According to the diameter of the pipe, the tractionshelf could be adjusted to appropriate position. It uses Cycloid pin wheelreducer, drive low traction shelf screw, then makes the low traction shelf turn,so that the traction shelf position is moved.
