Description

Technical Field

[0001] The utility model relates to the technical field of composite felt processing, and specifically relates to an antistatic web laying device for polyphenylene sulfide (PTFE) composite felt. Background Art

[0002] Polyphenylene sulfide PTFE composite felt is a kind of felt made of polyphenylene sulfide and polytetrafluoroethylene. This kind of felt has excellent chemical corrosion resistance, flame retardancy and dimensional stability, and at the same time has the flexibility, high wear resistance and tear resistance of PTFE. Polyphenylene sulfide PTFE composite felt is a material with excellent performance and is widely used in many fields.

[0003] When polyphenylene sulfide (PPS) PTFE composite felt is laid and rolled, static electricity will be generated. Especially when processing polymer materials, static electricity will be generated due to the friction and separation between materials. Static electricity can easily cause dust to be adsorbed on the fiber surface, which will affect the surface quality of the product. For example, it may cause stripes, spots or affect the gloss and adhesion of the coating. Excessive static electricity will cause the material to adhere to the equipment, affecting production efficiency. At the same time, cleaning the adhered material will also increase costs and production time. The uneven accumulation and distribution of static electricity will lead to quality problems in the products produced, such as inconsistencies in parameters such as thickness and gloss. Therefore, we propose an anti-static laying device for polyphenylene sulfide PTFE composite felt to ensure the smooth progress of the production process. Utility Model Content

[0017] Before the polyphenylene sulfide PTFE composite felt is rolled, the polyphenylene sulfide PTFE composite felt is laid on the base cloth according to the production requirements to ensure that it is flat and wrinkle-free. Then water is poured into the water tank 3 and absorbed by the sponge block 4 in the water tank 3. At the same time, the other side of the sponge block 4 is attached to the rubber roller 6. The rubber roller 6 is driven to rotate by the rotating shaft 5 to keep the surface moist.

The moist rubber roller 6 can reduce the pressure between the roller surface and the polyphenylene sulfide PTFE composite felt. Friction coefficient, reduce the generation of static electricity, use rubber roller 6 to press the polyphenylene sulfide PTFE composite felt, which has good friction performance and conductive performance.
