Small blown film machine factory laboratory blowing machine inspection and maintenance

Inspection maintenance

Check the traction speed control film thickness.

3 to observe and adjust the film thickness uniformity, folding size standard.

The inspection of the air storage cylinder pressure is not too high, but due to standby pressure.

The check and control the ratio of raw materials mixed evenly.

The inspection of raw materials has no impurities, especially should check with the iron magnet.

But check the gear box and the air compressor cylinder lubricating oil lubrication.

The regular inspection of the operating temperature of the motor and mechanical transmission.

Laboratory blowing machine maintenance - targeted maintenance items

1. feeding machine system: clean the filter in time, check whether the negative pressure feeding system leaks or not.

2. extruder system:

Observe the pressure instrument and main motor current, clean the screen changer in time

Check the gear box, screw, main motor, whether the noise and overheating

Check frequency of converter, current, temperature rise, clean motor, converter dust on time.

Correction of thermocouple measurement and actual temperature error.

Adjust the placement of extruder, adjust groove wheel to ensure the placement angle and level of extruder.

3. die system:

Start the heating and take two heating methods to avoid the temperature overshoot.

Before using the copper scraper, clean the deposit, paraffin, clean the membrane and reduce the influence of the precipitate on the film bubble.

After stopping the machine, cover the felt timely and avoid the damage of the mould. (blowing machine adopts this method)

Check the temperature, the current and the temperature of the heating plug at the temperature zone and the film port regularly.

Adjust the head level and match the center point with the traction.

The mould screws use torque wrench, torque according to the rules of operation of the high temperature part of the screw, using molybdenum disulfide grease.

The prohibition of welding, cutting die.

4., wind ring maintenance: timely cleaning of the wind ring debris and dust

5. traction device maintenance: herringbone folding, pollution-free, clamping, traction (cooling) roller suitable pressure, no condensation water, flattening roll operation flexible.

6. corona processor maintenance:

Clean the high voltage transformer, discharge roller, discharge rack, electric control box regularly, adjust the discharge gap;

Check the humidity of the equipment before starting, avoid the short circuit of the discharge rack, and check the running temperature of the discharge roller bearing,

Change the silicon tube in time.

7. electrical maintenance

Guarantee the stability and reliability of the power supply, and meet the requirements of the performance parameters,

Maintain suitable temperature and humidity, maintain good grounding, and pay attention to eliminate static electricity.

Clean the radiator dust regularly.

Prohibit the maintenance of core components with parts.
