Description

Technical Field

[0002] Silicone asphalt blanket is a polymer composite material widely used in fields such as building waterproofing, industrial sealing, and high-temperature protection. It is based on asphalt and is compounded by adding components such as silicone modifiers and reinforcing fibers. It has excellent weather resistance, high temperature resistance, and aging resistance. During the production process of silicone asphalt blanket, the continuously formed wide material usually needs to be cut into finished products or semi-finished products of specific sizes and shapes according to actual needs. This process places high demands on the precision, efficiency, and adaptability of the shearing equipment.

[0004] However, when using the device to cut the asphalt blanket, the cutting blade will generate high temperature through friction when it contacts the asphalt blanket, which will cause molten asphalt to form on the cutting surface, resulting in an uneven cut during the secondary cutting. In addition, harmful gases will be generated during the high-temperature cutting of the asphalt blanket, and it is necessary to suppress the generation of harmful gases by blowing air. In addition, due to the characteristics of the asphalt blanket, the position of the asphalt blanket will be offset due to changes in tension on both sides of the processing section during cutting, and the asphalt blanket needs to be limited.
