Extrusion machine operating procedures, specific points, thank you!
6, the speed from low to high, added to the normal speed, is strictly prohibited high-speed car, observe the instrument on the current value and temperature is normal, in case the current is too large, cause the heater to burn.7, when lifting the disk, we should pay attention to the limit of the rise and fall, not too high or too low, when there is an electrical limit, shall not exceed the limit.8 when feeding to the hopper, be careful not to enter the metal, and do not use a screwdriver or a metal bar to poke the plastic into the screw.9 check the dry test machine, should be equipped with rubber insulation plate, otherwise, no driving.10 before driving, should check whether the ground location is good, grounding resistance should be measured regularly, not higher than 4 Europe; equipment whether there is noise and other anomalies, if there is a problem, repair and reuse.
1, operators must be familiar with the procedures, the safety test qualified, wear good protective equipment, shall operate the equipment.2 when the power is on, check whether the thermal control of the electric appliance is sensitive and reliable, whether the thermocouple indicates the temperature is correct or not, and if there is a problem, please repair the personnel to exclude them.3 when driving, should check the main reducer, traction non polar transmission, the line is stepless gear box lubrication is normal, fan ventilation is good.4 before driving, pay attention to the heating temperature of each section, whether the actual temperature required by the process, the heat preservation time should be enough, and the initial heating time can not be less than 3 hours heat preservation.5, not in the plastic bad, scorched, aging, extrusion production, in case of accidents, and found the above problems, immediately try to rule out.
11 prohibit the use of hand to touch the dry test machine high-voltage appliances, electrical wiring or ground wire parts.No water on the 12 wire core.13, do not stop before the hand touch insulated wire core, wire connector and exposed parts; after high voltage breakdown, the wire core should first take discharge measures, and then repair.14 driving and parking should be directed by skilled workers to avoid misuse and risk.15, equipped with softening equipment, plastic machine, the operator can not arbitrarily move, adjust electrical and mechanical equipment; can not touch the wire, electric pulley, copper catheter parts.16 after the end of the drive, the power supply, water source and air source should be all closed, and the operation handle will be replaced in place, and the records of the shift shift will be kept in good order.
