1.1 What Is a Film Blowing Machine?

A Film Blowing Machine is an automated piece of equipment that controls the film production process through a pre – set program. Compared to the film – blowing process without automated control, the programmable operation of the Film Blowing Machine can save materials and time while ensuring the consistency and quality of the film. These machines can be programmed as needed to meet different production requirements. Film Blowing Machines are suitable for a variety of fields, such as food packaging, industrial packaging, agricultural film, and other occasions where automated film production is required. The machine automatically completes these tasks, so operators do not need to remember complex operating procedures, nor do they need to manually adjust the machine at specific times each day.

2.2 How Does a Film Blowing Machine Work?

A Film Blowing Machine completes the production of film through the following steps:

Material Feeding: The machine is equipped with a feeding system that delivers raw materials (such as polyethylene granules) into the machine, usually through a hopper.

Extrusion: The raw materials are heated and melted in the extruder to form a uniform melt. The extruder pushes the melt towards the die head through the rotation of the screw.

Blown Film Formation: After being extruded from the die head, the melt forms a film tube. Air is blown into the film tube through a blowing device, causing it to expand into the desired film shape.

Cooling and Setting: The expanded film is cooled and set through a cooling device, usually using air ring or water ring cooling technology to ensure that the film maintains a stable size and performance during the cooling process.

Drawing and Winding: The cooled film is drawn by a drawing device and then wound into rolls by a winding device. The speed and tension control of the drawing device are crucial to the quality of the film.

Inspection and Quality Control: Film Blowing Machines are usually equipped with an inspection system to check for defects or irregularities in the film, ensuring that only high – quality film passes through the production line.

Slitting and Packaging: According to customer needs, the film can be slit into different widths and lengths. The slit film can then be automatically packaged and stacked for storage or transportation, usually using robotic arms or conveyor belts.

Safety Measures and Machine Maintenance: Film Blowing Machines are equipped with safety features to protect operators and prevent accidents. Regular maintenance of the machine is necessary to keep it in optimal working condition.

Through the above steps, the Film Blowing Machine achieves full – process automation from material feeding, extrusion, blown film formation, cooling and setting, drawing and winding, inspection to packaging. Combined with precision engineering and automation mechanisms, it ensures efficient and consistent film production.
