1. Usage: The EPC can detect the edge position of the film and automatically adjust the system to ensure that the film stays in the correct position throughout the production process. This helps ensure uniform width of the film, improving product quality.
2. Reducing Waste: By ensuring that the film stays in the correct position during production, the EPC helps reduce unnecessary film waste. This contributes to increased production efficiency and lower production costs.
1. Usage: used to recycle and reuse the waste edges generated during the film production process.
2. Resource Utilization and Cost Reduction: The recycling system collects, processes, and reutilizes the discarded film edges. By recycling this waste material, manufacturers can minimize waste generation, enhance resource efficiency, and reduce production costs, as recycling trim helps in minimizing material wastage.
The crushed waste material can be refilled into the screw in time to avoid affecting the output and computer calculation
The film width controller adjusts the film width by air replenishment and air release. The specific process is as follows:
Air replenishment: When the film width is insufficient, the control system will increase the air pressure of the extruder head by air replenishment, thereby pushing the edge of the film to expand outward to reach the required width.
Air release: On the contrary, when the film width is too large, the control system will release some gas, reduce the air pressure of the extruder head, and cause the edge of the film to shrink and return to the ideal width.
This dynamic adjustment mechanism can respond to changes in film width in real time, ensuring that the production of the film meets the set specifications, thereby improving product quality and production efficiency.
The dryer reheats and dries the polyethylene granules before they are fed into the screw to remove excess moisture and improve the quality of the blown film.
