II. Detailed Explanation of Driving Methods of PE Film Blowing Machines​

What are the differences in the driving methods of PE film blowing machines? Be cautious when choosing?​

(1) Traditional Belt Drive Method​

Firstly, there is the traditional belt drive method, which is a common way to drive the entire machine through an electric motor that drives the belt. This method is simple and reliable, with low maintenance costs, but limited by a single driving method, it cannot achieve precise speed control and is also susceptible to external environmental influences.​

(2) Frequency Converter Speed Regulation Drive Method​

Next is the variable speed drive method using a frequency converter. By installing a frequency converter, the motor speed can be adjusted, thereby achieving precise control of the film production speed. This method can reduce energy consumption and improve production efficiency, but installation and maintenance costs are relatively high.​

(3) Servo Motor Drive Method​

The latter is the servo motor drive method, which is advanced and can achieve high-precision speed control and positioning control using servo motors. The servo motor drive method has obvious advantages in energy conservation, efficiency, and stability, but the corresponding cost is also relatively high.​

III. Automation Advantages of PE Film Blowing Machines​

The PE film blowing machine adopts an automated control system, which is simple and convenient to operate, has high production efficiency, and saves labor costs. By adjusting the speed of the extruder and die, the thickness of the film can be controlled within a certain range to ensure stable product quality. The PE film blowing machine can produce PE films of different specifications and uses according to needs, and has strong adaptability.​

IV. Analysis of the Production Process of PE Film Blowing Machines​

The PE blow film machine melts and extrudes the PE resin through an extruder, and processes it into a thin film of the required thickness and width through a die head. Then, the film is stretched by a stretching mechanism to give it a certain tensile strength and transparency. Next, the film is cooled by a cooling roller to rapidly solidify. Finally, the thin film is rolled into rolls through a coiling machine, making it convenient for subsequent processing and use.​
