Daily care and maintenance of the blow molding machine

The blow molding machine requires daily maintenance and maintenance. Regular cleaning of the extruder barrel, screw, die head assembly and molding die, regular lubrication of moving parts, careful maintenance of the machine, keeping the raw materials clean and the workplace clean will help Long-term normal operation of the blow molding machine. Daily maintenance and maintenance of the blow molding machine: (1) Whether the mold clamping device is normal and reliable. (2) Check whether the fixing of the heating ring (heating plate) is firm and whether the wiring is short-circuited. (3) Check the motor oil pump, piping and valves for oil leakage and water leakage. (4) Check the liquid level of the fuel tank. (5) Check the flow of cooling water and mold cooling medium. (6) Check whether there is any abnormal noise in the motor oil pump, piping, valve, etc. (7) Check the oil temperature. The temperature of the hydraulic oil is generally in the range of 35℃-50℃ after the machine starts to run for several hours. When the oil temperature exceeds 60℃, it must be shut down for cooling. (8) Check whether the system pressure is normal. (9) Check the extruder components, manifold components and die for glue leakage. (10) Check whether the guide rod of the closing cutter assembly is worn, whether the gap between the front cutter and the rear cutter is appropriate, and whether the cooling effect of the cutter is appropriate. (11) Check the pneumatic system for problems. (12) Check whether the lubrication of each moving element by the central lubrication system is sufficient. (13) Check whether the safety gate limit switch is in good condition and the trigger is normal. If it is not normal, it cannot be turned on. (14) Check whether the on-off valve of the main oil circuit and the feedback input of the spool are triggered normally. If not, the machine cannot be started.
