Preferably, the periphery of the carding bar is densely covered with fur.
Compared with the prior art, the utility model has the advantages and positive effects that:
(1) Through set up negative pressure suction device at the conveying curtain, adsorb the fibre web both sides limit on the conveyer belt, the conveyer belt is along with conveying curtain synchronous forward, takes the fibre web off, can not cause the turn-ups because of the air current, causes cloth cover wrinkling, inhomogeneous, influences the quality of non-woven fabrics finished product.
(2) The suction ports are arranged along the conveying direction of the conveying belt, so that suction force is continuously provided for the fiber net, the adsorption effect is improved, and the fiber net is turned over.
(3) The roller is arranged above the suction port, and the conveyer belt is put on the roller under the influence of gravity, so that friction is reduced.
(4) The servo motor drives the carding rod to rotate, the fiber web deploy with folds is provided, the spiral carding rod has more and irregular action points on the fiber web, and better carding effect is achieved. The periphery of the carding rod is densely covered with fur, and the efficiency of scraping the fiber web folds is higher.
