Three-tier co-extrusion blown film machine maintenance
Dalian blown film machineManufacturer ask everyone summed up three layers co-extrusion blown film machine maintenance mode:
1, plastic blown film receive coil winding diameter gradually increases as usual this time please pay attention to the cooperate with traction speed and winding speed, can adjust in time.
2, usually plastic blow molding machine may be damaged during transit electrical components or thrum off some things, we should be strict inspection, but in order to ensure the personal safety, the line must be connected before starting the next step is to connect the power supply, then apply strict inspection parts whether plastic film blowing machine motor operates normally, and note if there is any leakage.
Plastic blow molding machine 3, during the installation, in checking a few times, should also pay attention to see the center line of the extruder head with traction roll axis vertical and level whether there is any deviation may not make it askew.
4 after host open again, plastic blown film machine, should pay attention to the host running situation and adjust from time to time, amend, electric meter, controller, observe if there is any abnormal or damaged, and in a timely manner to repair or replacement, to ensure the normal operation of plastic film blowing machine.
5, host, gear box, traction reducer to often come on, change gear oil (oil level to achieve scale line), the new general change in the use of 10 days after the new gear oil, to determine the rotational parts can normal operation, to prevent overheating and damage of the difficulty of working, you should also check the connection parts of tight situation, to prevent the occurrence of loose bolts.
6 plastic blow molding machine, preheating, heat cannot too long and too high, in order to avoid jams mouth;Conditions can use the automatic temperature control system, set up the tolerance automatic temperature stable, convenient and safe.
7, always clean up to replace the filter on the inside the nose, can prevent blockage, beware of plastic particles mixed with iron, sand, stone shaw in dirty things such as falling within the cylinder, thereby avoid screw with a nitrogen-treated barrel of some damage.
8, it is forbidden to carry empty machine case of regulated, in the cylinder, tee, die temperature, that do not meet the requirements can't start the host.
9, start the main motor, should be to accelerate slowly, when start the motor after reaching for speed stability;Close the main motor, should slow down after power off.
10, bubble tube in the compressed air should be kept in a balanced state, in the process of traction load, plastic blown film machine, blown film will be compressed air leak out, timely supplementary effect.
