Jwell
Jwell PET decorative film production line is designed to manufacture high-quality PET films used in various decorative applications, such as interior design, packaging, and labels. These films are valued for their clarity, strength, and versatility. Here is an introduction to the main components and the production process of Jwell PET decorative film production line:
1. Raw Material Handling and Feeding System:
- Hopper: Feeds raw PET pellets into the extrusion system.
- Dosing Units: Precisely measure and mix raw materials, including any additives or colorants.
2. Extruder:
- Single-Screw or Twin-Screw Extruder: Melts and homogenizes the PET material.
- Barrel and Screw: Designed for optimal mixing and melting of the material.
- Heating Elements: Maintain precise temperature control to ensure consistent material flow.
3. Screen Changer and Melt Pump:
- Screen Changer: Filters out impurities from the molten PET.
- Melt Pump: Ensures a consistent and controlled flow of the molten plastic to the die.
4. Sheet Mould:
- T-Die: Shapes the molten PET into a flat sheet with the desired width and thickness.
- Adjustable Lip: Allows fine-tuning of the sheet thickness.
5. Calendering Unit:
- Three-Roll Calender: Comprises a series of heated and polished rollers that smooth and shape the sheet, controlling its thickness and surface finish.
- Gap Adjustment Mechanism: Ensures precise control of sheet thickness.
6. Cooling System:
- Cooling Rollers: Gradually cool the sheet to solidify it while maintaining its dimensional stability.
- Water Baths or Air Cooling Units: Further reduce the sheet's temperature as needed.
7. Embossing Unit (optional):
- Embossing Rollers: Impart decorative patterns or textures onto the PET film.
8. Corona Treatment Unit:
- Corona Treater: Increases the surface energy of the film, enhancing its adhesion properties for printing or coating.
9. Edge Trimming and Slitting Unit:
- Edge Trimmers: Remove the edges of the sheet to ensure uniform width.
- Slitting Blades: Cut the sheet into desired widths if multiple smaller sheets are needed.
10. Haul-Off Unit:
- Pull Rollers: Draw the sheet through the extrusion line at a controlled speed, ensuring uniform thickness and preventing stretching.
11. Winding Unit:
- Roll Winder: Collects the finished film onto rolls for easy handling, storage, and transport.
- Tension Control: Ensures even and tight winding of the film.
12. Control System:
- PLC (Programmable Logic Controllers) and HMI (Human-Machine Interface): Monitor and control various parameters of the extrusion process, such as temperature, pressure, speed, and thickness, ensuring consistent product quality.
13. Quality Control and Inspection Station:
- Sensors and Imaging Systems: Inspect the film for uniformity, defects, and other quality parameters.
1. Feeding and Melting: Raw PET pellets are fed into the extruder, where they are melted and homogenized by the rotating screw and heating elements.
2. Filtering and Pumping: The molten PET is filtered to remove impurities and then pumped to the die at a consistent flow rate.
3. Sheet Formation: The molten PET is extruded through the T-die, forming a continuous flat sheet.
4. Calendering: The hot sheet passes through a series of calender rollers, which smooth and shape it to the desired thickness and surface finish.
5. Cooling: The sheet is gradually cooled using cooling rollers and possibly additional cooling units to solidify and stabilize its dimensions.
6. Embossing: If decorative patterns or textures are required, the sheet passes through embossing rollers.
7. Corona Treatment: The sheet undergoes corona treatment to increase its surface energy, improving adhesion for printing or coating.
8. Trimming and Slitting: The edges of the sheet are trimmed to ensure uniform width, and the sheet is slit into the required widths if necessary.
9. Haul-Off: The sheet is drawn through the production line by pull rollers, ensuring consistent speed and tension.
10. Winding: The finished film is wound onto rolls for storage and transportation, with tension control to ensure even winding.
11. Quality Control: Throughout the process, various parameters are monitored and controlled to ensure the film meets quality standards.
This production line is designed for high efficiency and precision, producing PET decorative films with excellent clarity, mechanical properties, and surface quality. These films are widely used in applications requiring attractive, durable, and versatile decorative materials.
