1. Introduction
In the field of plastic processing, double-layer film blowing machine is a widely used equipment, which is mainly used to produce plastic films with special functions. This machine can blow two different plastic materials into a layer of film at the same time, thus forming a film product with composite properties. This article will discuss the technical principle, structural composition and application field of double-layer film blowing machine in detail.
2. Technical principle
The working principle of double-layer film blowing machine is to heat and melt two different plastic raw materials separately, and convey them to a co-extrusion die through two independent screw extruders. Inside the die, the two molten plastic materials are evenly mixed together under specific pressure and temperature conditions, and blown into film through an annular die. Since the distribution of the two plastic materials in the film can be precisely controlled, film products with different performance characteristics can be manufactured.
3. Structural composition
The double-layer film blowing machine is mainly composed of the following parts:
1. Screw extruder: responsible for heating and melting the plastic raw materials and conveying them to the die.
2. Die head: Mix the molten plastic material evenly and form a film shape.
3. Blowing device: Blow the film from the die head into a film of the required thickness and width.
4. Cooling system: Used to quickly cool the newly formed film to achieve the required physical properties.
5. Winding device: Wind the cooled film into a roll for easy storage and transportation.
4. Application field
The application range of double-layer film blowing machine is very wide, including but not limited to the following fields:
1. Packaging industry: Double-layer film can provide better barrier, heat resistance and moisture resistance, suitable for packaging of food, medicine and other products.
2. Agriculture: Double-layer film can be used as agricultural covering film to improve the yield and quality of crops.
3. Construction industry: Double-layer film can be used as building waterproof material to improve the durability and safety of buildings.
4. Electronics industry: Double-layer film can be used as insulating material for electronic products to improve the reliability and stability of products.
5. Conclusion
As a high-efficiency production equipment, double-layer film blowing machine plays an important role in the plastic processing industry. By rationally selecting and adjusting the types and proportions of plastic raw materials, high-performance film products that meet various needs can be manufactured. With the advancement of technology and changes in market demand, it is believed that double-layer film blow molding machines will have broader development prospects in the future3
