The invention relates to a longitudinal adhesive tape arranging mechanism matched with a screw compressor. The longitudinal adhesive tape arranging mechanism comprises an adhesive tape fixing device and a pressing device. The pressing device comprises a pressing wheel, rocker arms and a rocker arm fixing cross rod. The outer side of each side vertical plate is fixedly connected with a rocker arm connecting shaft. One end of each rocker arm is connected to the corresponding rocker arm connecting shaft in a sleeving manner, and the other end of each rocker arm is fixedly connected with a pressing wheel shaft provided with the pressing wheel. A spring used for pressing the pressing wheel and a material forming cylindrical face is arranged between each rocker arm and the corresponding side vertical plate. By means of the longitudinal adhesive tape arranging mechanism matched with the screw compressor, the inner diameter of the middle portion in the pressing wheel is large, the direct contact area of the shaft and the pressing wheel is reduced, the rotating resistance of the pressing wheel around the shaft is reduced, and sliding is flexible; and the rocker arms are fixedly connected with spring fixing pins, the side vertical plates of a support are also fixedly connected with spring fixing pins, tensile springs are installed on the two fixing pins, and the rocker arms and the pressing wheel can be pressed on the material forming cylindrical face.
