PTFE (polytetrafluoroethylene) film is a high-performance polymer material film made from PTFE resin through a special process. It has a perfluorinated linear structure, excellent temperature resistance (-190 ℃~260 ℃), chemical inertness (resistant to strong acids, alkalis, and organic solvents), extremely low friction coefficient, excellent electrical insulation, non adhesiveness, and hydrophobicity. Part of the PTFE membrane is stretched to form a microporous structure, which combines breathability, waterproofing, and filtration functions. Mainly used in fields such as electronic and electrical insulation, chemical anti-corrosion liners, medical implant materials, building waterproof breathable membranes, industrial non stick coatings, etc
The present invention is a central winding device for PTFE proton exchange materials, suitable for winding sheets and films such as LCP.FEP.TPU. CPE.CPP. PET. PPS. It involves food packaging. Industrial building materials. Electronic communication. New energy. In the field of new materials.
The coiling equipment adopts a new type of turret type dual station central mechanism. Equipped with AB axis automatic switching. Automatic cutting of materials. Automatic flipping and material replacement. Assist in traction and stretching. Center+friction+clearance comprehensive function.
The structure of the coiling device is as follows:
1. Auxiliary traction parts; There are 2 active silicone sticks available. Driven by servo motor. S-shaped guiding material. Non pressed state. Plays an auxiliary traction role. Eliminate surface tension and wrinkles of materials.
2. Surface friction areas. There is one passive silicone roller installed. During work, it extends from the cylinder. Control the linear track slider to make contact with the material in the X direction. Follow the size of the material roll diameter. Automatically move position. Always maintain contact friction. Eliminate surface wrinkles and slippage during winding of materials. The cylinder pressure can be flexibly and freely adjusted through an electromagnetic proportional valve. Control the contact gap. Meet the winding requirements of different materials.
3. cutting locations. Adopting a hidden flip up structure. When cutting, the knife holder flips upwards from the bottom. After cutting the material, it automatically falls down and hides in the base position. Not obstructing operation and maintenance space. Eliminating safety hazards and maintaining compact locations. Equipped with rodless cylinders. Flip frame. Easy to disassemble and maintain.
4. winding positions - equipped with AB dual stations. Bidirectional flipping frame. Hidden independent drive structure. Replaced for conductive copper ring wiring and short-circuit faults. Drive on the same axis. AB does not interfere with each other.
5. tension monitoring locations. Use universal joints and pressure bridge pressure sensors. Replaced the floating tension of the swing arm. Under equal roles and functions. Saved installation space.
6. The entire coiling equipment uses carbon fiber guide rollers. Reduce surface friction while. Reducing the weight of the guide roller itself. Increased mechanical strength.
7. Operation process; S0 material - S1 auxiliary traction device S-shaped guide - S2 tension part - S3 friction part - S4 cutting part - S5 winding part.
