How To Maintain The Bottle Blowing Machine

1. Daily maintenance of bottle blowing machine

Check whether the mold clamping device is normal. The mold clamping device is the core component of the bottle blowing machine and needs to be checked frequently for normal operation.

Check whether the heating coil (heating plate) is firmly fixed and whether the wiring is short-circuited. The heating coil is the heating component of the bottle blowing machine and needs to be guaranteed to operate normally.

Check whether the motor oil pump, piping, and valve have oil and water leakage. The motor oil pump, piping, and valve are hydraulic components of the bottle blowing machine and need to be guaranteed to operate normally.

Check the oil tank level. The oil tank level needs to be kept within the normal range to ensure the normal operation of the hydraulic system of the bottle blowing machine.

Check the flow of cooling water and mold cooling medium. The cooling water and mold cooling medium need to ensure normal flow to ensure the normal operation of the cooling system of the bottle blowing machine.

Check whether there are abnormal sounds in the motor oil pump, piping, valves, etc. Abnormal sounds may be a signal of a problem with the bottle blowing machine and need to be handled in time.

Check the oil temperature. The temperature of the hydraulic oil is generally in the range of 35℃-50℃ after the machine starts running for several hours. When the oil temperature exceeds 60℃, the machine needs to be shut down for cooling. The oil temperature needs to be kept within the normal range to ensure the normal operation of the hydraulic system of the bottle blowing machine.

Check whether the system pressure is normal. The system pressure needs to be kept within the normal range to ensure the normal operation of the hydraulic system of the bottle blowing machine.

Check whether the extruder assembly, the manifold assembly and the die head have glue leakage. Glue leakage may affect the production efficiency and product quality of the bottle blowing machine.

Check whether the guide rod of the closed 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. The cutter assembly needs to ensure normal operation to ensure the production efficiency and product quality of the bottle blowing machine.

Check whether there is any problem with the pneumatic system. The pneumatic system needs to ensure normal operation to ensure the production efficiency and product quality of the bottle blowing machine.

Check whether the central lubrication system has sufficient lubrication for each moving component. The central lubrication system needs to ensure normal operation to ensure the production efficiency and product quality of the bottle blowing machine.

Check whether the stable door limit switch is intact and triggered normally. If it is not normal, the machine cannot be started. The stable gate limit switch needs to be guaranteed to operate normally to ensure the safety of the blow molding machine.

Check whether the main oil circuit on-off valve and valve core feedback input are triggered normally. If not, the machine cannot be turned on. The main oil circuit on-off valve and valve core feedback input need to be guaranteed to operate normally to ensure the normal operation of the hydraulic system of the blow molding machine.

2. Regular maintenance of the blow molding machine 

In addition to daily maintenance, regular deep maintenance is also required, including cleaning the inside of the machine, replacing worn parts, and checking the electrical system. The specific maintenance cycle can be determined based on the frequency of use of the machine and the manufacturer's recommendations.

3. Preventive maintenance of the blow molding machine

To prevent potential problems, preventive maintenance can be performed regularly, such as checking whether fasteners are loose, cleaning filters, and checking conveyor belts. This helps to extend the service life of the machine and improve production efficiency.

It should be noted that the above steps are for reference only, and the specific maintenance steps may vary depending on the machine model and manufacturer. Therefore, when performing maintenance, please always refer to the machine's operating manual and the manufacturer's recommendations. If you are not sure how to perform maintenance, it is recommended to contact a professional maintenance person or the manufacturer's technical support team.
