The noise muffler makes the bearing cage have the characteristics of low noise, high strength and high production efficiency. The effective application of welding technology can not only ensure the bearing performance, but also automatically separate the changes in current and voltage, thus improving the product quality. The giant grooved cast iron roll is a new type of roll developed by our company in 2002, and has passed the provincial appraisal. The utility model has the advantages of uniform aperture hardness, wear resistance, long service life, smooth surface of rolled products, accurate size, etc., which can improve the quality of rolled pieces by 2-3 times. However, graphite floats on the roller surface after spheroidizing treatment, which can not meet the requirements of modern high efficiency and high quality. This paper analyzes, digests and develops a set of winding system of high-speed plastic flat film drawing machine suitable for woven bag machinery. The production of muffler can make the winding speed of drawing machine reach 400m / min, and the winding speed of wire drawing machine can reach normal production.
