Since the Heidelberg SM102 was put into production, it was found that after the printing press stopped suddenly, the trailing part of the paper would sag onto the bridge of the unit, and then be full of oil. When the machine printed again, the oil would pass through the paper and reach the surface of the roller The surface of the printing cylinder and the surface of the rubber cylinder cause the oil to pass to the surface of the finished paper and produce waste products. In this way, after the emergency stop, all the surfaces of the rollers with oil sticked on it should be wiped clean with a clean rag before the printing machine can be restarted for normal production. This situation causes a reduction in work efficiency and the quality of the produced products cannot be guaranteed. Consulted with the engineers of Heidelberg, the answer is that the intellectual property rights cannot be cured. Heidelberg SM102 is installed in every machine in different places. The customers of the printing factory report that the oil is leaking badly, and Heidelberg has never improved. After observation and analysis, the oil lubrication system of SM102 has made waste oil penetration holes in the machine wall board. Each oil penetration hole is connected with the waste oil return groove of the bridge underneath. Collected in a waste oil basin at the eighth floor and then processed and recycled. The key problem now lies in the return groove, where the waste oil will overflow onto the platform across the bridge. When the paper trailing tip touches the platform across the bridge, it will stick to the engine oil, causing downtime to process book reviews and wasting time . There are now two solutions to this problem. The first option is to use a 1CM square sponge strip, apply double-sided tape on one side, and then stick the sponge strip to the platform on both sides of the groove, covered with a layer of film (plastic pads, etc.), so that the paper trails No oil will stick to the sagging. As far as printing is concerned, Chinese printing companies have basically solved the problem, but then new problems have emerged, that is, the oil will still penetrate from the platform and then flow into the chassis of the machine, causing waste oil to deposit and difficult to clean. Then another solution is to connect a pipe (metal or plastic) Corey to the oil seepage holes on both sides of the wall. The inner diameter of the pipe should be as large as possible to keep the waste oil flowing smoothly. The joint between the oil hole and the pipe is sealed with sealant. The waste oil is directly led into the large return plastic pipe from the pipe. (The pipe needs to be fixed at the groove to prevent the pipe from moving out of the groove.) Return to the waste oil basin. In this way, the waste oil will not leak out to the Beiren Group, the bridge platform, nor will it flow into the machine chassis, which can completely get rid of the harm of waste oil to printing.
