The machine of bottle blowing machine needs daily maintenance. Regular cleaning of the barrel, screw, die head components and forming mold of extruder, regular lubrication of moving parts, careful maintenance of machinery, clean raw materials and clean workplace are conducive to the long-term normal operation of the machine.

Daily maintenance of bottle blowing machine:

(1) Whether the clamping device is normal and reliable.

(2) Check whether the heating coil (heating plate) is fixed firmly and whether the wiring is short circuited.

(3) Check the motor oil pump, piping and valve for oil leakage.

(4) Check the tank level.

(5) Check the flow of cooling water and mold cooling medium.

(6) Check the motor oil pump, piping, valves and other places for abnormal noise.

(7) Check the oil temperature, the hydraulic oil temperature is generally in the range of 35 ℃ - 50 ℃ after the machine starts to run for several hours.

If 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, splitter plate components and die head for leakage.

(10) Check whether the guide rod of the closed cutter assembly is worn and whether the clearance between the front cutter and the rear cutter is appropriate,

Whether the cooling effect of cutter is appropriate.

(11) Check the pneumatic system for problems.

(12) Check whether the central lubrication system has sufficient lubrication for each moving element.

(13) Check whether the safety gear threshold switch is in good condition and the trigger is normal. If it is abnormal, it cannot be started.

(14) Check whether the on-off valve of the main oil circuit and the feedback input of the valve core are triggered normally. If not, it cannot be started.
