high-speed manual screen changer is a component used in film blowing machines to quickly and efficiently remove impurities and achieve uninterrupted production of plastic films. It is designed to handle the demands of high-speed film production and can be manually operated without pausing the machine.
The screen changer is placed in the extrusion line between the extruder and the die head. It incorporates a filtration system that consists of one or more screens with different mesh sizes. These screens help to remove contaminants, such as gels, paper, and other foreign particles from the molten plastic.
In a high-speed manual screen changer, the operation is performed without stopping the production process. When the screens become clogged with contaminants, the operator manually rotates a lever or turns a handle to switch to a clean screen pack, while allowing the contaminated one to be cleaned or replaced.
This type of screen changer allows for quick and efficient screen changes, minimizing downtime and maximizing productivity. However, it requires manual intervention from an operator and may require supervision to ensure smooth operation.
