The recycling waste plastic pellet machine industry is called a plastic granulator. When using a plastic granulator, turn on the power in turn, set the temperature and pay attention to whether the heating is normal, for how to effectively control the temperature of the main machine of the plastic machine.

Clean the hopper and other units, the inlet and outlet pipes, and check the oil level and lubrication status of the gear oil, engine oil, and high-temperature butter. The gear oil of the new machine should be replaced every six months at the latest, and the movable parts should be lubricated at least once a week. When the temperature is approaching the set temperature, prepare the materials and start the main motor in turn. The temperature of the pellet machine must reach the set temperature, and the feeding device can be turned on to pour the cleaning material or the raw material to clean the residue in the screw until the new material is extruded, then the extruding is suspended, and the filter plate and die are installed quickly in place. The die head can be closed. After closing the die head, turn on the main screw motor of the pelletizer. The operator will stay away from the die head at this time to prevent the hard material from blocking the die head and bursting and hurting people until the die head extrudes the filaments, and then close The pelletizing cover is connected to the cutting tool holder and locked.

After the above operations are in place, turn on all auxiliary machines in sequence: fan> vibrating screen> pelletizer> main engine operation.

When the pellets are discharged normally, the pelletizer is adjusted, and the particle size is adjusted by frequency conversion speed regulation. The screw must keep the pelletizer rotating before discharging. If it is a water-cooled spray pelletizer, the pelletizer hood must be filled with water first, and finally the host is turned on for formal production. Start the extrusion host and adjust the frequency conversion speed of the host and the pelletizer slowly and quickly according to the particle size requirements. Only when the two are coordinated, can the cut particles be better uniform and the output of particles can be maximized.

The order of stopping production is opposite to the order of starting production. First turn off the main engine drive, then turn off the auxiliary power supply, and finally clean the die head quickly to prevent the die head from cooling and clogging. For more information about the plastic pellet machine, please refer to the plastic recycled pellets Use, (special attention: the die outlet filter plate must be completely cleared after each shift operation is stopped before it can be installed again for production, otherwise the die head may explode due to clogging).

In production, the raw materials enter the auger grinder to be crushed and cleaned, and then discharged into the cleaning tank. Under the action of the fork, the scraps are moved forward and cleaned again. The feeder removes the material from the tank and enters it. The hopper smoothly falls on the screw from the hopper, is twisted by the screw, and is forced forward by the screw as the screw rotates. When the heating furnace is heated, it generates heat with the compression and stirring movement of the plastic itself under the action of external and internal forces. The temperature of the plastic increases rapidly to make the material melt into liquid form, uniformly extrude from the barrel, and then enter the negative machine for stirring and squeezing. Due to the resistance of the filter screen, the splitter plate and the machine head, the material is formed in the process With strong pressure, the bar material is pressed very tightly so that the plastic is uniformly discharged from the pores in the strip shape, then falls into the pool for cooling, and finally enters the pelletizer to cut the surface of the pellet.
