The normal start-up steps of the plastic film blowing machine
1.Heat the eatruder body,die head,and control the temperature of each point within the index.
2.If the machine is turned on after a long-term stop,the heating temperature of each point needs to be kept constant for 10-30 minutes after reaching the target range.If the machine is turned on within half an hour of parking,no constant temperature is required.
3.Start the air compressor and stop when the cylinedr pressure is 6-8kg/cm.
4.According to the film folding diameter,thickness requirements and extruder production capacity for processing,estimate the pilling speed and stable bubble diameter.
5.After the temperature of each point meets the requirements,put on labor protection supplies,and tsart the tractor,blower,and extruder in order.
6.Check the film thickness and width of the plastic film blowing machine and adjust them to meet the requirements.
7.When the die outlet is uniform,you can slowly pull the tube blank while wearing gloves,and at the same time,close the end of the tube blank to blow a small amount of compressed air from the center hole of the mandrel.
