Design of Porous Pipe Auxiliary Positive Pressure Range Extension Device in Smoke Stick Filter Forming Equipment
[Purposes]In view of the situation that the working stroke of the filter rod increases due to in-stallation,manufacturing tolerance and other reasons in the transmission process,which leads to the in-terruption of the transmission process,the method of positive pressure auxiliary transmission of porous pipeline is proposed.[Methods]When the air flow in the positive pressure pipe flows through the posi-tive pressure hole,it will exert a radial movement on the filter rod.Because the drum wheel itself has its own speed,the centrifugal force generated will exert a tangential movement on the filter rod.The dis-placement in these two directions can realize the continuous transmission of the filter rod in the space po-sition and increase the transmission distance between the drums.[Findings]Through the analysis and calculation of the pressure loss in the pipeline,the positive pressure hole was designed and improved.The device can effectively reduce the installation and manufacturing accuracy and increase the transmis-sion distance of the transfer drum.[Conclusions]While improving the working efficiency of the conveyer drum,the repeated processing or repair of the parts is avoided,and the diversity of the spatial design and arrangement of the conveyer drum is possible.
