Maintenance and Troubleshooting of Bottle Blowing Machine

Bottle blowing machine maintenance and troubleshooting are critical to ensuring stable production efficiency and extending the service life of your equipment.Below are the common faults and corresponding maintenance methods for bottle blowing machines, helping you solve problems quickly and improve production efficiency. All operations are applicable to the bottle blowing machine products on our official website.

1.No Material Feeding at the Feeding Station

When there is no material feeding at the feeding station, please check the following situations step by step: First, confirm whether the hopper of the bottle blowing machine is empty. If the hopper is empty, add materials immediately to ensure the normal operation of the production line. If the hopper is not empty, check whether the control contactor of the elevator is energized. If it is in the energized state, quickly check whether the motor is energized and under load. This situation is mostly caused by preforms stuck on the lifting belt, and the simplest solution is to assist lifting manually to remove the stuck preforms.
If the control contactor of the elevator is not energized, please check whether the preform detection electric eye is aligned with the reflector plate. Misalignment will cause the machine to fail to detect preforms, thus stopping feeding. Adjust the position of the electric eye and reflector plate to ensure they are on the same straight line.

2.Frequent Jamming at the Feeding Disk

Jamming at the feeding disk is a common and troublesome fault in the operation of bottle blowing machines. According to practical experience, this problem occurs less frequently when the preforms used are long in length and heavy in weight. If jamming occurs frequently, you can check whether the preforms are deformed or have burrs, and replace unqualified preforms in time to avoid affecting the feeding efficiency.

3.Blown Bottles Cannot Be Ejected from the Mold

When blown bottles cannot be taken out of the mold, first open the mold and test manual mold opening and closing. If the manual operation is normal, run the bottle blowing machine in idle mode to check whether the mechanical structure operates smoothly. If both tests are normal, check the exhaust time setting of the machine. If the exhaust setting is correct and the fault occurs every time blowing starts, it can be judged that the problem is with the exhaust valve.
Open the exhaust valve to inspect the spring and seals. If the spring is loose or the seals are worn, replace them in time. It should be noted that this fault is often accompanied by loud exhaust noise or incomplete exhaust sound. If the mold fails to open occasionally during normal production, check whether there are broken screws in the mold locking pins, and verify whether the mold locking force is too high. Adjust it to the standard value according to the equipment manual.

4.Frequent Clamping Damage to Bottles

If the produced bottles are always clamped and damaged, the main reason is usually the misalignment of the manipulator position. Please stop the machine and check the position of the manipulator, adjust it to the standard position according to the equipment parameters, and ensure that the manipulator clamps the bottles stably and gently to avoid clamping damage.

5.Collision Between Two Manipulators

Collision between two manipulators of the bottle blowing machine is mostly caused by manipulator misalignment. When this situation occurs, stop the machine immediately to avoid further damage to the equipment. Then reset the manipulators manually according to the operation manual, and check whether the positioning of the manipulators is accurate after reset to ensure that the two manipulators operate independently without interference.
Regular maintenance and timely troubleshooting of bottle blowing machines can effectively reduce fault occurrence and improve production efficiency. For more details about bottle blowing machine maintenance and product information, please visit our official website.
