Wall panel extrusion equipment The extruder is a common plastic machinery and equipment. During the daily operation of the extruder, various failures occur in the extruder, which affect the normal production of plastic machinery. Out-of-machine failure analysis.
1. Reasons for production:
⑴Uneven feeding. ⑵ The main motor bearing is damaged or poorly lubricated. ⑶ A certain section of the heater fails and does not heat up. ⑷The screw adjusting pad is wrong, or the phase is wrong, and the components interfere.
2. Treatment method:
⑴Check the feeder and troubleshoot. ⑵ Overhaul the main motor and replace the bearings if necessary. (3) Check whether the heaters are working normally, and replace the heaters if necessary. ⑷Check the adjustment pad, pull out the screw to check if there is any interference in the screw.
The main motor of the plastic extruder cannot be started
1. Cause:
⑴ There is an error in the driving procedure. ⑵There is a problem with the main motor thread, and whether the fuse is burned. ⑶The interlocking device related to the main motor works
2. Treatment method:
⑴Check the procedure and restart the car in the correct driving sequence. ⑵ Check the main motor circuit. (3) Check whether the lubricating oil pump is started, and check the status of the interlocking device related to the main motor. The oil pump cannot be turned on, and the motor cannot be turned on. ⑷The induction power of the inverter has not been discharged, turn off the main power supply and wait for 5 minutes before starting. ⑸ Check whether the emergency button is reset.
The plastic extruder head is not smooth or blocked
1. Reasons:
⑴ A certain section of the heater does not work, and the plasticization of the material is poor. ⑵The operating temperature is set too low, or the molecular weight distribution of the plastic is wide and unstable. ⑶ There may be foreign objects that are not easy to melt.
2. Treatment method:
⑴Check the heater and replace it if necessary. ⑵Verify the set temperature of each section, negotiate with the technician if necessary, and increase the temperature set value. ⑶ Clean and check the extrusion system and head.
