Method and Device for Recycling and Granulating PP Composite Medical Drip Soft Bags

A device for recycling and granulating PP composite medical drip soft bags, comprising:

• a hopper, receiving a fragment mixture of a recycled PP composite medical drip soft bag;
• a heating and kneading unit, connected to the hopper, receiving the fragment mixture from the hopper and heating and kneading the fragment mixture to a predetermined temperature and then advancing;
• a first die, connected to the heating and kneading unit to filter and extrude the fragment mixture after heating and kneading;
• a cooling unit, connected to the first die to cool and advance the extruded fragment mixture;
• a second die, connected to the cooling unit for shaping and granulating the cooled fragment mixture to form a plurality of particle materials;
• a water channel, connected to the second die to transport and clean the particle materials;
• a dehydrator, connected to the water channel to dehydrate and transport the cleaned particle materials;
• a vibration screening unit, connected to the dehydrator and vibrating to screen the particle materials according to different sizes;
• and
• a plurality of storage barrels, arranged adjacent to the vibration screening unit to collect the particle materials with respective sizes.
