Daily PET blowing machine Maintenance and Maintenance Automatic Blow Molding Machine requires daily maintenance and maintenance. Regularly clean the barrel, screw, die assembly and molding die of the extruder, regularly lubricate the moving parts, and carefully maintain the machine.

2. Keeping the raw materials clean and the work place clean will help the 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 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 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 for abnormal noises in the motor oil pump, piping, and valves.

(7) Check the oil temperature. The temperature of the hydraulic oil is generally within the range of 35 ℃ -50 ℃ after the machine starts running for several hours. When the oil temperature exceeds 60 ℃, it will be cooled down.

(8) Check if the system pressure is normal.

(9) Check the extruder assembly, manifold assembly and die for leaks.

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

(11) Check if there is any problem with the pneumatic system.

(12) Check whether the lubrication system is adequately lubricated for each moving element.

(13) Check whether the door limit switch is intact and triggered normally.

(14) Check whether the main oil circuit on-off valve and valve core feedback input trigger normally.
