1. Check whether the screws are loose and whether the rotation of each spindle is flexible.
2. Correctly install each motor and its wiring. The motor adopts three-phase 380V heating plate and adopts 220V current.
3. Make good grounding protection outside the machine.
4. Check whether the rotation of each spindle of the test machine is correct.
5. The heating plate is powered and preheated until the outer shell of the barrel melts the foam, and pay attention to the fact that the raw materials in the upper and lower barrels must be completely melted before each extruder is started, so as to rotate the large wheel flexibly. Due to the residual raw material melt in the machine head, it is recommended to use a blowtorch to strengthen the preheating of the upper and lower machine heads.
6. Flexibly control the length of the drawn rod into the water, depending on the temperature and water temperature, cool the drawn rod by about 1.1-1.7M in water, so that the drawn rod is not brittle and broken, and does not stick after cutting.
7. Observe the color and shape of Xinji foam machinery, and flexibly grasp the power supply and shutdown of each heating element.
8. If there are many impurities such as ash and soil in the raw material, 20-40 mesh and 1-3 layers of sieves can be added before the screen to ensure the color and purity of the particles.
