An elastic inner drawstring ring is fitted at the discharge spout. The spout expands when material is discharged; after discharging stops, the elastic structure retracts automatically to tighten the outlet, effectively preventing negative-pressure air backflow in workshops from carrying dust into the bag and contaminating materials.
The fully sealed structure works with dust removal assembly lines to greatly improve workshop environmental dust indicators. Structural dimensions and elastic tension can be customized and adjusted according to production line working conditions.
