First, the purpose
Standardized equipment operation and plastic pelletizer maintenance, the purpose is to ensure the normal operation of equipment and extend the life, reduce maintenance costs and improve production efficiency.
Second, the scope of application
Applicable to the company’s production of TPR / EVA / PVC / Color Masterbatch / no halogen cable / rubber high-filled engineering materials and other production line equipment operating instructions.
Third, the special duties
The equipment designated by the use of units of special operators and maintenance personnel shall not be illegal operation, and must be skilled in the operation of equipment, to supervise the unrelated personnel shall not be close to and tamper with the damage to the equipment duties.
Fourth, the operating rules
⒈ turn on the power, set the temperature and pay attention to whether the normal heating.
⒉ clean the hopper and other units, out of the water pipe, check the gear oil, oil, high temperature butter oil level and lubrication state, the new machine gear oil replacement at least six months, the activities of the site at least once a week to add oil.
⒊ temperature is close to set the temperature, prepare the material and start the main motor in turn.
⒋ the temperature of the extruder must reach the set temperature, open the feeding device can be poured into the cleaning material or raw material cleaning screw residue, until the new material out, and then pause squeeze material, quickly installed in place the filter plate and mold head. Can close the die, close the die after the start of the granulator main screw motor, the operator at this time away from the die, to prevent the die hard material clogging bursts of injury, until the die out of the wire, and then close Cut the shroud and connect the cutting tool holder and lock it.
⒌ above the operation in place followed by the order to open all the fans>; vibrating screen>; granulator>; host operation.
⒍ normal grain adjustment when the pelletizer, frequency control to adjust the particle size. The screw must be kept in the material before the pelletizer rotation, if it is water spray spray type, cut the first mask to water, and finally open the host for the official production.
⒎ start the extrusion host and slow and fast according to the particle size needs to adjust the host and the pelletizer frequency control, only to achieve the coordination of the two in order to make the particles even better uniform and maximize the amount of particles.
⒏ stop the operation sequence and the boot operation of the reverse order, the first off the host drive, and then turn off the auxiliary power supply, and finally quickly clean up the die to prevent the die cooling blockage (special attention: The hole and the filter plate must be completely clear to install the production again, otherwise the die due to the risk of plugging the explosion).
