[0002] The SMS nonwoven fabric production line integrates meltblown, hydroentangling, and other processes, enabling it to produce various nonwoven fabric products with different properties to meet the needs of diverse applications. The SSMS production line boasts high production efficiency and flexibility, and is widely used in hygiene products, medical supplies, and industrial filter media.

[0003] The first step in production is to add raw material particles such as polypropylene, which is usually done using a vacuum powder feeder. The specific feeding process is as follows:

[0004] Raw material particles (such as polypropylene) are stored in a silo and then conveyed from the silo to a vacuum powder feeder via a screw conveyor. The vacuum powder feeder uses negative pressure to quickly suck in the raw material particles and precisely controls the feeding amount. The feeder continuously and evenly injects the raw material particles into the melt flow to ensure a stable supply of raw materials.

[0005] This vacuum feeding method can achieve precise metering and rapid delivery of raw materials, ensuring a continuous supply and uniform proportion of raw materials throughout the production process. However, in actual application, a large amount of dust may be generated during the absorption and delivery of particles, which will affect the normal operation of the equipment and the stability of the feeding.
