Description

Technical Field

[0002] Polypropylene, abbreviated as PP, is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and is resistant to a variety of organic solvents and acid-base corrosion. It has a wide range of applications in the industrial field and is one of the common polymer materials. The physical stability, mechanical strength, and airtightness of the film are good, the transparency and gloss are high, and it is tough and wear-resistant. The main disadvantage of polypropylene film is its poor heat-sealing property, so it is generally used as the outer film of composite films. For example, after being compounded with polyethylene film, its moisture-proof property, transparency, strength, stiffness, and printability are all ideal, and it is suitable for packaging dry food.

[0003] After retrieval, the Chinese patent application number CN202221592859.2 discloses a cutting device for polypropylene film production, including a lower fixed plate, an upper fixed plate, and a cutting knife. The top of the lower fixed plate is connected with a lower roller through an elastic support, and the bottom of the upper fixed plate is connected with an upper roller through an elastic support. When the lower roller and the upper roller are in contact in the natural state, there is a gap between the upper and lower cutting knives. An installation box is also fixedly connected to the upper fixed plate, and a power structure for driving the lower roller and the upper roller to rotate actively is arranged in the installation box.

[0004] During the slitting process of the above device for polypropylene film, it is not convenient to adjust the distance between the slitting blades, resulting in a small application range of the device. Therefore, the utility model provides a slitting device for producing anti-fog polypropylene film. Content of the Utility Model
