Today, with the increasingly fierce competition in the packaging material market, PE Embossed Film Machine has become the preferred material in the fields of food, daily chemicals, industrial packaging, etc. due to its excellent mechanical properties, beautiful embossed effects and wide applicability. The cast PE embossed film production line has become a core weapon for enterprises to improve production efficiency, reduce costs and seize the market with its efficient, stable and flexible technical characteristics.
1. Technical advantages: dual breakthroughs in cooling system and drive design
Efficient cooling system: breaking through the bottleneck of high-speed operation
Large diameter cooling roller + two-way loop design:
The production line uses a large diameter cooling roller (diameter ≥800mm) with a special two-way loop cooling system to ensure that the cooling water circulates evenly in the roller, and the surface temperature difference is ≤±1℃. This design solves the problem of film surface deformation and embossing blur caused by local overheating of traditional cooling rollers, so that the production speed can reach 120-150m/min, which is more than 50% higher than traditional equipment.
Diversified cooling method combination:
Vacuum pre-cooling: vacuum adsorption (vacuum degree ≥-0.08MPa) is used to quickly reduce the film surface temperature in the front section of embossing to reduce the risk of thermal deformation.
Air knife precision control: high-pressure airflow (wind pressure 0.3-0.5MPa) is used to accurately adjust the cooling speed of the film surface to ensure the consistency of embossing depth (±0.01mm).
Soft bellows supplementary cooling: for the edge area of the film surface, low-temperature soft bellows (water temperature ≤15℃) are used to strengthen cooling, and the scrap rate is reduced to less than 1%.
Low noise and high torque drive: the core guarantee of stable operation
The production line adopts a permanent magnet synchronous motor (energy efficiency level IE4) and a high-precision gearbox combination, which increases the drive torque by 30% and reduces the noise to ≤75dB, ensuring that the equipment can remain stable under high-speed operation.
Dynamic load balancing technology: by real-time monitoring of motor current and roller speed, the drive parameters are automatically adjusted to avoid unstable film surface tension caused by load fluctuations, and the product qualification rate is increased to more than 99%.
2. Efficiency improvement: Automation and intelligence drive production capacity leap
Full process automation: reduce manual intervention
Automatic roll change and flying joint system:
The production line is equipped with a fully automatic flying joint roll change device, which shortens the roll change time from the traditional 5 minutes to 30 seconds, reducing downtime losses.
Intelligent slitting control:
Using laser thickness gauge and AI algorithm, the slitting parameters (such as knife distance and tension) are adjusted in real time, the slitting accuracy reaches ±0.1mm, and the scrap rate is reduced to less than 2%.
Closed-loop control system: Real-time optimization of production parameters
Temperature-tension-pressure three-loop control:
Through high-precision sensors (temperature ±0.5℃, tension ±0.5N, pressure ±1%), real-time feedback data to the PLC system, automatically adjust the cooling water flow, roller speed ratio and embossing roller pressure to ensure the stability of embossing depth and film thickness uniformity.
Energy consumption optimization algorithm:
Dynamically adjust the motor power according to the production stage (such as automatic frequency reduction of 50% when shutting down), and reduce unit energy consumption by 15%-20%.
