The invention discloses a hot air delivering device for nonwoven fabric production equipment. The hot air delivering device comprises a device body, mounting blocks are arranged on both opposite innerwalls of the device body, slide grooves are formed in both opposite sides of two mounting plates and are internally provided with slide blocks, grooves are formed in both sides of each slide block, movable rods are rotatably connected to both inner walls of the two grooves, inserting rods are arranged on the side walls of the movable rods, inserting grooves corresponding to the inserting rods positionally are formed in the inner walls of the slide grooves, device cavities are formed in the side walls of the mounting blocks, worm wheels are rotatably connected to the inner walls of the devicecavities, worms are arranged on the side walls of the mounting blocks, penetrate through the side walls of the mounting plates and extend into the device cavities, one end of each worm is rotatably connected to the inner wall of the corresponding device cavity, a rotary wheel is fixedly connected to the end, away from the inner wall of each device cavity, of the corresponding worm, and a circularcavity is formed in the inner wall of each inserting groove. The hot air delivering device for the nonwoven production equipment is reasonable in structural design and easy to operate, and pollution of dust and bacteria in air to nonwoven fabric is lowered.
