PE blown film machine, as an important production equipment, has a wide range of application prospects in modern industrial production. It not only meets the market demand for PE film products, but also provides strong support for the production of plastic products. The main advantages of PE blown film machine include high production efficiency, low production cost, simple operation, and easy maintenance. By adjusting components such as extrusion heads and coolers, films of different thicknesses and widths can be produced to meet the needs of different industries.

The film produced by PE blown film machine is widely used in the packaging industry. For example, in the field of food packaging, the produced PE film can be used to make food packaging bags, such as various snack bags, frozen food bags, etc. Due to its excellent flexibility, barrier properties, and corrosion resistance, PE film can effectively protect the quality and safety of food. In daily necessities packaging, packaging bags for products such as shampoo and shower gel are also made of thin films produced by PE blown film machines.

What skills do beginners need to master when operating a PE blown film machine?

Familiarity with equipment structure and working principle: Novices should have a basic understanding of the structure and working principle of the PE blown film machine before operating it. Only by deeply understanding the working principle of the equipment can one better master the operating skills.

Adjusting screw speed and temperature: The speed and temperature of the screw are key parameters that affect film production. Novices need to adjust the screw speed and temperature reasonably according to production requirements and different film varieties to ensure the stability of the production process.

Controlling the temperature and speed of the cooling roller: The cooling roller plays a crucial role in the formation and quality of the film. Novices need to adjust the temperature and speed of the cooling roller according to the thickness and quality requirements of the film to ensure the uniformity and transparency of the film.

Pay attention to the processing and extrusion of the material liquid: When operating the PE blown film machine, pay attention to the processing and extrusion process of the material liquid. Novices need to master the processing methods and extrusion techniques of the liquid to ensure the uniformity and stability of the extrusion outlet.

Regular cleaning and maintenance of equipment: PE blown film machine is a type of equipment that requires regular cleaning and maintenance. Novices need to regularly clean the impurities inside and outside the equipment when operating it, replace worn parts in a timely manner, and ensure the normal operation of the equipment.

Pay attention to safe operation: When operating the PE blown film machine, beginners need to pay attention to safe operation. Strictly follow the operating procedures, use protective equipment correctly, and avoid accidents.

Continuously learning and improving skills: Novices operating PE blown film machines need to constantly learn and improve their skills. Only through practice and accumulated experience can we better master operational skills, improve production efficiency and product quality.

In the operation of the PE blown film machine, it is necessary to first heat and melt the PE raw material through the extruder, and then blow out the film through the die. The film will be cooled by a film cooling system, then processed by a stretching system and coiled into a roll by a coiling system. The entire production process requires operators to monitor and adjust to ensure product quality.

When shutting down, first stop adding plastic particles to the hopper. Then gradually reduce the speed of the extruder screw and turn off the heating system. After the plastic inside the extruder barrel is basically emptied, close the inflation air valve, traction device, and cooling device. Turn off the power to the entire device and clean it, removing any remaining plastic film from the mold head, traction device, and winding device.
