In order to keep the granulation system of the plastic granulator in good working condition, the newly installed or overhauled plastic granulator is necessary for the following inspection and test operation before it is officially put into production and application:

 

① Adjust the moving stroke of the granulating seat so that the nozzle can resist the sprue sleeve of the mold. It should be noted that the adjustment should be carried out under low pressure and after the mold is closed to ensure the safety of the mold.

 

② Check whether the nozzle used is suitable for the processed material. If it does not meet the type, it should be replaced and can be smoothly assembled to the front end of the barrel. Nozzle before installation should also pay attention to the passage is not smooth.

 

③ Adjust the metering stroke and anti-salivation stroke of the screw through the travel switch or displacement sensor, and pay attention to whether the travel switch or sensor is smart and reliable.

 

④ Adjust the pressure of granulation and the pressure of holding pressure. Switching from the pressure of granulation to the pressure of holding pressure is mainly adjusted by the time relay.

 

⑤ Adjust the pressure of the back pressure, the pressure of the nozzle control hydraulic cylinder and the pressure of the granulation seat cylinder. These test runs are carried out by adjusting the rocker of the hydraulic drive system relative to the valve.

 

⑥ Check whether the moving guide rail of the granulating seat is clean and greased.

 

⑦ Run the pre-plastic screw for 5 seconds to check whether there is any abnormal scraping sound and whether everything is normal when opening and closing the silo.
