The production process of PE blown film machine mainly includes steps such as raw material mixing, extrusion blown film, cooling and forming, winding and packaging. Operators need to regularly maintain and clean the equipment to ensure the smooth progress of the production process. In addition, operators also need to master certain production techniques to ensure the quality and production efficiency of the film.

The PE blown film machine is mainly composed of feeding system, extrusion system, die head system, cooling system, traction system, winding system and other parts. The feeding system sends the raw material particles into the screw, melts them at high temperature, and then extrudes the melted polyethylene into a film through the extrusion system. The die head system is a key component of the entire blown film machine, and different die head designs can produce film products of different thicknesses and widths. The cooling system can quickly cool and solidify the hot film, ensuring product quality. The traction system evenly stretches the film through traction rollers to ensure uniform thickness of the film. The winding system winds the finished product onto the core, facilitating subsequent processing and use.

How to choose a PE blown film machine? How to maintain and upkeep?

1、 Selection of PE blown film machine

The selection of PE blown film machine is related to production efficiency and product quality, and can generally be considered from the following aspects:

1. Production scale: Choosing the appropriate production capacity and specifications of PE blown film machine according to the production scale can ensure production efficiency and product quality.

2. Equipment quality: Choosing PE blown film machines from well-known brands and reputable manufacturers can ensure equipment quality and after-sales service.

3. Convenience of operation: Whether the operation of the PE blown film machine is simple and easy to learn, whether there is a humanized design that can improve operational efficiency and reduce operational difficulty.

4. Energy consumption level: Choosing an energy-saving PE blown film machine can reduce energy consumption and production costs.

5. After sales service: Choosing a manufacturer with a comprehensive after-sales service system can promptly solve equipment failures and maintenance issues, ensuring the normal operation of the equipment.

2、 Maintenance and upkeep of PE blown film machine

PE blown film machine is a mechanical equipment, and daily maintenance is crucial for extending equipment life and ensuring production efficiency. Here are some common maintenance methods for PE blown film machines:

1. Regular cleaning: Regularly clean the surface and internal components of the PE blown film machine to maintain cleanliness and hygiene, and prevent dust, dirt, and other substances from entering the equipment and affecting production.

2. Lubrication and maintenance: Regularly lubricate and maintain the transmission system, bearings, gears, and other components of the PE blown film machine to ensure normal operation and reduce wear and tear.

3. Inspection and maintenance: Regularly check whether the various components and connecting parts of the PE blown film machine are loose or worn, and promptly repair or replace them to avoid affecting production due to faults.

4. Work environment: Keep the working environment of the PE blown film machine clean and tidy, avoid dust, debris and other substances from entering the equipment, which may affect production quality and equipment life.

5. Training operators: Provide professional training and skill development to operators, improve their operational skills, and reduce the possibility of equipment misoperation and malfunction.

When choosing the driving method for a PE blown film machine, it is necessary to consider both production needs and budget comprehensively. The traditional belt drive method is suitable for general production needs and is relatively affordable; The variable speed drive mode of the frequency converter is suitable for situations where production speed is required and requires appropriate investment; The servo motor drive method is suitable for situations that require high production accuracy and stability, and requires higher investment. Careful consideration should be given when making a choice, and appropriate choices should be made based on actual needs.

The PE blown film machine is mainly composed of extruder, die head, cooling roller, winding part and other components. The extruder is used to heat and melt PE particles, and then extrude them through a screw. The die is used to extrude and blow the melted polyethylene into a thin film. The cooling roller is used to cool the thin film, and the winding part is used to roll up the blown thin film.
