Before starting the heating system of the waste plastic granulator pelletizer, each mature (temperature control table) of the electric control cabinet of the waste plastic granulator pelletizer should be carefully checked. Whether the set value of the temperature control table is consistent with the temperature requirements of the process (the temperature of the general chemical plastic barrel is set to 180~230℃, and cannot exceed 300℃). First, turn on the temperature of the die head of the granulation main machine and auxiliary machine. Generally, the temperature is heated for about 2 hours to about 150~160℃ before the 7 die temperature switches of the granulation main machine and the 3 die temperature switches of the auxiliary machine are turned on.

The single die head shall adjust the tone of the medium plate filter to about 35mm of the exposed sealing surface. After the heating system of the waste plastic granulator pelletizer is started, the die head shall not be pumped again. (The new granulator in the first heating process directly pumping the die head may cause die surface strain, must be turned on and there is glue from the template out, then the middle template down in place, continue the test machine. In the normal production process, this method can also extend the service life of plastic granulation machine die head).

The double die head should slightly deviate the middle plate from the working station by about 35mm. After starting the heating system, the die head should not be pumped again. (In the first heating process of the new machine, direct pumping of the die head may cause die surface strain. When the machine is started and the glue comes out from the template, the middle template shall be dropped into place and the test machine shall continue. In the normal production process, this method can also extend the service life of plastic granulation machine die head).

Check whether the current indicating value of each hub heater is normal, and the heating time should be sufficient. Generally, after meeting the process requirements, the temperature should be constant for about 5 minutes, and the manual turning is more light.

Start the main motor of the waste plastic granulator pelletizer (when configuring the speed regulating motor or installing the frequency converter, first adjust the speed regulating or frequency conversion knob to the low-speed 5HZ~15HZ, and then start the motor, the speed regulation process should be uniform and slow, the speed should gradually increase). Pay attention to the change of the motor current.

If auxiliary feeding system, cooling system and lubrication system are installed, start auxiliary feeding system, cooling system and lubrication system.

If there is no abnormality when the waste plastic granulator pelletizer rotates, it can start blanking, preferably with a little blanking, until there is material extrusion. Barrel feed is above the funnel, with spiral feed; The snakeskin bag is underneath the funnel, with a spiral. Barrel material should not be fed to the lower funnel, lest feeding too fast, may block the main screw. At this time, check whether the curing degree of the rubber material and the required temperature of the cartridge mouth is normal until the die head has a certain amount of rubber material extrusion, then the machine can be stopped, the filter screen, mobile screen plate. Small plastic granulators can only feed barrel material, snakeskin bag material because there is no screw feed to the main screw.
