A down suction device and processing method for down processing

ActiveCN118929557BImprove weight measurement accuracyGuaranteed vacuuming effectUpholstery manufactureDispersed particle filtrationTextile technologyElectric machine
This invention belongs to the field of textile technology, specifically a down-collecting device and processing method for down processing. It includes a down-filling hopper, an adjusting unit at one end of which contains a down-washing unit, and a pressure-relief unit within the down-washing unit. The invention uses an electric telescopic rod to move a filter plate inside the down-filling hopper away from the three-phase motor until the down inside the hopper is compressed to a designated area on one end of the electronic scale. Simultaneously, a crank connecting rod rotates, and a pressure-relief plate, under the control of a panel, rotates at a certain angle within the filter plate. This allows for real-time control of the alignment between the filter holes in the pressure-relief plate and the mesh of the filter plate. During this process, a pressure-relief valve extracts gas from inside the down-filling hopper to the outside, ensuring a vacuum in the down-retention area, eliminating the influence of air buoyancy, reducing airflow interference, effectively avoiding static electricity, improving the accuracy of the electronic scale's weight measurement, and ultimately improving product quality control precision.
