The invention discloses a discharging adjusting mechanism for textile machinery equipment. The discharging adjusting mechanism comprises a discharging base plate; a discharging roller frame, a heightbalancing roller frame, a dust removal filter sleeve and a tensioning main frame are sequentially arranged on the upper surface of the discharging base plate from left to right; an upper discharging roller and a lower discharging roller are symmetrically arranged on the discharging roller frame; the middle of the upper discharging roller and the middle of the lower discharging roller are connectedto the discharging roller frame through rotating shafts; textile yarn on the upper discharging roller is wound around a height balancing roller on the height balancing roller frame for one circle; adust collecting groove base is arranged between the dust removal filter sleeve and the height balancing roller frame; an adjusting supporting plate is connected to the tensioning main frame through anadjusting groove; tensioning rolling wheels are symmetrically arranged on the left side and the right side of the tensioning main frame and the lower part of the tensioning main frame; an adjusting rolling wheel is arranged on the upper part of the adjusting supporting plate through an upper rotating shaft; and the adjusting supporting plate is connected to a top side plate of the tensioning mainframe through a limiting base plate. The discharging adjusting mechanism has the advantages that dust removal treatment can be carried out on the textile yarn, and the tension degree of the textile yarn can be adjusted.
