Precautions and Operation

1. Preparation before production (1) Check if parts and components are damaged, screws are loose, wires and cables are damaged or lost. If there is any damage, replace or repair them in time. (2) Check if there is any debris in the hopper of extruder and clean it up, then close the discharge gate. (3) Check if the moving parts are firm, especially where the impact force is strong, and check if the belt transmission part is normal. (4) Check the high and low pressure air source, power supply and water supply. (5) Check the emergency stop switch, safety door switch and protection device. (6) Check if any pneumatic component leaks gas. (7) Please operate according to the operation manual. 2. Production in the normal course When the machine is working, a person should be assigned to supervise it and handle any issues. As this 30L oil bottle blow moulding machine enjoys high degree of automation, the workload during normal production is quite low. Users just need to add raw materials at regular intervals, and collect finished products and burrs at designated position of this 5L oil bottle blow moulding machine.


For optimal performance and extended service life, please regularly inspect and maintain this oil bottle blowing machine. 1. During the normal production, please lubricate the machine according to the lubrication schedule. If stop using the machine for more than a month, apply rust-proof oil to each guide pillar, and cover the pillar with sheet to prevent dust and other corrosive substances. Regularly clean and oil the pillars. 2. According to statistics, more than 85% of failure of hydraulic system is caused by pollution of hydraulic oil, so it is of great importance to keep the hydraulic oil clean and extend the service life of the hydraulic system. The hydraulic system of this oil bottle blowing machine allows maximum oil pollution of NAS 1638 11. No corrosive substance is allowed to be mixed in the hydraulic oil, and the oil shall be filtered by filter with the filtration precision of 2020μ. 3. Daily routine check Check the temperature of the hydraulic oil, and adjust the cold water supply when necessary to keep the oil temperature between 30 and 50 degrees. 4. Weekly routine check (1) Lubricate each part. (2) Whether the stroke switch of installation screw is off. (3) Whether there is oil spill in the oil pipes and joints, and tighten them if necessary. (4) Whether the machine is leaking oil or gas. 5. Monthly routine check (1) Whether the joints of each circuit are loose. (2) Whether the hydraulic oil is clean and sufficient. Clean the air cleaner. (3) Whether the filter is blocked. (4) Lubricate the lubricating parts. (5) Whether the exhaust fan works, clean the dust on the dust net and replace the net in time to avoid influencing heat dissipation of electric box. (6) Whether the water can flow smoothly, and whether there is any scale deposit. (7) Check the extrusion belt. 6. Annual routine inspection (1) Replace the pressure oil to extend the service life of oil valve, oil pump and sealing rings. (2) Clean thermocouple contact points. (3) Check all wire connection points in the electric box to see whether the rubber shell of each wire is hardened to prevent leakage. (4) Check all indicator lights. (5) Clean the motor. Dust on the motor housing may lead to difficulty in heat dissipation. (6) Clean up the scale deposits. (7) Clean the tank of hydraulic system. (8) Check the pneumatic system.

Failure Analysis and Troubleshooting

Accidental failure is inevitable in the continuous operation of the 30L oil bottle blow moulding machine. Here are some of the common troubleshooting methods:

Mechanical Transmission


Analysis and Solution

Motor workload increase 1. Damage of gearbox bearing. 2. Severe friction between screw and barrel. 3. The plasticization temperature of raw materials is not enough.
Noisy gearbox 1. Bearing failure. 2. Insufficient or dirty lubricating oil. 3. The wear or crack of gear box.

Pneumatic Liquid Control

Direction valve doesn’t work 1. Dirty hydraulic oil or air; distortion of the valve core. 2. Blocking of return air or oil circuit. 3. Damage of direction valve coil or wiring off. 4. Valve core stuck or sealing leakage.
Unstable clamping force 1. Damage of clamping cylinder or oil cylinder seal (need to be replaced). 2. Wrong position or leakage of stop valve or reversing valve.
Oil temperature is too high 1. The oil tank is short of oil. 2. Not enough cooling water or serious fouling chiller. 3. Damage of overflow valve.
Insufficient air pressure and oil pressure 1. The wear of compressor or oil pump leads to the leakage. 2. Short of oil for the oil tank and entering of air for the oil pump (need to add hydraulic oil). 3. Blocking of filter and oil filter (need to be cleaned).

Electrical Control

The temperature of heating parts don’t rise, and the current meter doesn’t work 1. The power is not connected. 2. The connection of electric heating circuit is loose. 3. The electric heater is damaged by short circuit. 4. The current meter is damaged.
Extruder motor and oil pump motor don’t work or fail 1. Check if there is circuit failure or phase failure. 2. Check if the rotation direction of motor is right. 3. The pressure exceeds load or motor overload.
Swing frame doesn’t work 1. The blow pin must be raised to the upper limit and contact the limiting rod with the induction switch. 2. The die board must be in place.
The temperature of cutting knives can’t be controlled 1. Rotate the hand wheel of voltage regulator, then you can change the temperature of cutting knives. 2. Check the output voltage of transformer and it should be changed with the voltage regulator.
Machine can’t work normally 1. Check if the position of each limit switch is appropriate. 2. Check if the wring section is loose. 3. Damage of electric components.
