the joint of the side blowing device and the drafting device adopts an integrated integral structure;
further, the porous plate structure be adjustable structure, the porous plate bilateral symmetry sets up the multiunit bolt hole of highly different, the purpose is used for the screw that leads to because of factors such as site operation error highly inconsistent, can adjust both sides and adjust.
Preferably, 3 groups of bolt holes are symmetrically arranged on two sides of the porous plate, when the height of the porous plate needs to be adjusted, the screws on the two sides of the porous plate are loosened and screwed, then the porous plate is moved upwards to the required height, and the screws are screwed down on the porous plate until the positions of the bolt holes on the two sides of the porous plate correspond to the positions of the bolt holes of the frame, so that the height is adjusted;
after the height is adjusted, because the porous plate moves upwards for a section of displacement, a gap is generated between the lower edge of the porous plate and the drafting device, and the purpose is to realize large air exhaust; the moving displacement height of the porous plate is smaller than that of the drafting nozzle of the drafting device, namely, the drafting nozzle is higher than the gap size, and the stability of tows cannot be influenced.
4 drafting devices are arranged;
furthermore, the aperture ratio of the porous plate is determined through a plurality of tests, so that external air is not influenced on tows, and air can be discharged from the front, the back, the left and the right of the drafting device.
The principle of the utility model is that: the porous plate structure is designed, and the air exhaust is front, back, left and right, so that the stability of the air around the inlet of the drafting device is ensured;
the utility model has the advantages that: the lower rear part of the original side blowing device is closed, and the structure is improved into a porous plate structure with adjustable height; the defect that air can only be discharged through the left and right sides and the front side of the drafting device, and air flow cannot be uniformly discharged due to the closed rear side, so that tow is disordered is overcome; the stability of the air around the inlet of the drafting device is ensured, and the stability of the spinning tows is improved, so that the lapping effect is ensured.
