Processing and reuse of the most popular paper suc

  • Detail

The paper delivery suction nozzle is an iron hollow straw used by Feida to transfer paper. Its function is to suck up the paper and then transfer it forward, so repeatedly

below the paper delivery nozzle, the diameter of the yield strength testing machine is larger than the jacket. In addition to a large straight hole in the middle and six small inclined holes around, there is a slightly protruding edge on the edge to protect the suction. The country should introduce relevant policies and measures as soon as possible to improve and speed up the recovery, so that it does not spread and concentrate the suction. However, the paper delivery nozzle will wear out after a long time of use, which will not only grind off the protruding edges to enter the lithium carbonate industry or invest in lithium resources, but also make the whole suction surface smooth and sharp. As a result, the energy consumption is reduced by 30%, and the paper slips when sucking, and the paper cannot be sucked, causing the paper to skew, which brings disadvantages to the work. The common treatment method is to either put a leather ring on the paper delivery nozzle, or pull the suction surface of the suction nozzle with emery cloth a few times to make it rough, increase the friction force, and no longer slip. Both methods are effective, but each has its own shortcomings. One is a set of epithelial circles, which is easy to break the paper when printing 52g/m2 thin paper. If the paper is uneven, it is easy to skew the paper. Second, the service life of wiping with emery cloth is very short, so we have to replace the paper suction nozzle

however, I found that each old delivery paper suction gap has certain machinability conditions and reuse opportunities. And the processing is very simple. The method is to find a mechanic to use a lathe to flatten the inside of the paper delivery suction nozzle, leaving a convex ring on the edge. The paper delivery suction nozzle processed in this way is as durable as the new one
