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

PE blow molding machine is a powerful, efficient, and cost-effective plastic processing equipment, which is of great significance to the plastic film processing industry. With the continuous progress of technology, the performance and technology of PE blow molding machines will continue to improve, bringing better development prospects for the field of plastic film production.

The PE film blowing machine has the characteristics of high automation, high production efficiency, and uniform film thickness, which can meet various specifications and requirements for PE film production. At the same time, the PE film blowing machine adopts advanced control systems and energy-saving technologies, which can reduce energy consumption, reduce production costs, and meet modern environmental protection requirements.

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

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.

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.

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.

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.

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.
