Product Description
Automatic Opp Cast Film Line Machine is an automated production line equipment for producing OPP (biaxially oriented polypropylene) cast film. The equipment processes polypropylene raw materials into high-transparency and high-flatness films through extrusion, casting, cooling, pulling, winding and other processes, and is widely used in packaging, printing, electronics and other fields.
Cast Film Extrusion Line Features
High-precision control: equipped with PLC (programmable logic controller) and human-machine interface (HMI), which can monitor and adjust production parameters (such as temperature, speed, tension, etc.) in real time to ensure uniform film thickness (error within ±1μm).
High-efficiency extrusion: using high-efficiency screw extruder, the output can reach 200-500kg/h (depending on the model), and the energy consumption is reduced by 15%-20% compared with traditional equipment.
Intelligent detection: built-in online thickness gauge and defect detection system, which can feedback film quality data in real time, automatically adjust process parameters, and reduce the scrap rate to less than 1%.
Automatic winding: equipped with automatic roll changing device, the roll changing time is ≤3 minutes, and the production continuity is improved by 30%.
Cast Film Line Application Fields
Packaging industry: Transparent packaging film for food, medicine, and daily necessities, such as snack packaging and the inner layer of aluminum-plastic composite film for medicines.
Printing industry: As a printing substrate, it is used for labels, advertising posters, self-adhesive stickers, etc.
Electronic industry: Production of high-precision films such as capacitor insulation films and battery separators.
Agricultural field: Used for greenhouse covering films, silage packaging films, etc.
Maintenance points of Cast Film Machine
Daily cleaning:
After daily shutdown, wipe the surface of the equipment and the die head with a soft cloth to avoid hardening of residual raw materials.
Regularly clean the stains on the surface of the cooling roller and traction roller to prevent scratches on the film.
Regular inspection:
Check the wear of the screw and barrel every week, and replace the wearing parts if necessary.
Check the connection of the electrical system (such as sensors and inverters) every month to ensure stable signal transmission.
Lubrication and maintenance:
Add special lubricating oil to the transmission parts (such as gears and chains) every week to reduce wear.
Replace the hydraulic oil every quarter to avoid oil aging affecting equipment performance.
Die maintenance:
After every 50 tons of film is produced, the die is disassembled for deep cleaning to prevent carbonization of raw materials from blocking the flow channel.
When the machine is shut down for a long time, the die needs to be coated with anti-rust oil and sealed for storage.
Environmental control:
The production workshop maintains a constant temperature (20-25℃) and constant humidity (50%-60%RH) to prevent the film from shrinking or wrinkling due to changes in temperature and humidity.
Baijia Machinery Advantages
1. Dual-station unwinding structure enables rapid rewinding.
2. Use servo motor to drive the roller to ensure speed synchronization and appropriate longitudinal stretch ratio.
3. The longitudinal stretching part adopts a horizontal structure,Higher stability.
4. The longitudinal stretching part adopts automatic perforated film, which is easy to operate.
5. Use an oil circulation temperature control machine to accurately control the temperature of the rollers in the stretching section.
6. Use automatic tension control to ensure stable winding and appropriate tightness.
7. It adopts friction rewinding, automatic rewinding, film breaking, loading and unloading.
8. Cut multiple rolls online to reduce the post-cutting process.
9. The machine adopts PLC automatic control and is equipped with a human-computer interaction interface.
