The bearing iron roller is the necessary textile equipment for the spinning mill. It is combined with the upper apron and the apron frame; the lower apron of the middle roller forms a jaw; the cotton tampon is gripped; One of the components. It is the forced part in the transmission. Its quality can be directly produced when the quality of the yarn is good or bad. However, its processing quality is not the same as that of the top roller. The end of the process. And it; the leather roller only serves as a protection operation; the quality of the production depends entirely on the spinning mill. Usually we only need to strengthen the incoming inspection; the quality is not a problem. The quality of its protection mainly includes: regular cleaning, refueling, Radial, axial elimination view; reverse drilling and other operational requirements. And the iron roller surface rust and bonding problems are difficult to handle in each factory; often ignored or do not do. Because of the derusting of the craft Too annoying; it is even harder to avoid rusting. Here is a brief analysis of how to deal with this problem in our factory.
First, the rust is caused by the iron roller rusting in the touch of water or chemicals, air and other material conditions; talent is generated. And it protects the rotation between the roller and the special parts; often encounters a large change in temperature and humidity Because there is no air conditioning between the production and the special parts of our factory; even if there is air conditioning, it is difficult to control normally. Plus the iron roller is cleaned; because the cleaning liquid is also acidic; (because the new circle is treated by acid in the rubber factory) After the factory; and the roller is usually used directly on the new circle without neutralization; so the new circle is acidic.) Once the humidity is high, the iron roll is formed in large quantities; Long iron roll life is shortened; it also affects the quality of yarn.
Second, the rapid descaling method because the bearing iron roller is easy to rotate; the hand is difficult to grasp firmly; it is difficult to remove the rust with the iron sand leather craft; the power is low. We use the hydraulic roller rounding machine (A812 leather roller rounding machine also Can be the top of the roller; cover two sheets of 0# iron sand. The sand skin is fixed with three points of inner, outer, left and right sides of the adhesive plaster. The direction of the sand is fixed in the opposite direction to the rotation of the drum; Approximately 80 Ã— 10 a total of 6; can be fixed a sand. During operation; the starter motor is the upper press roller lift can be carried out. The method is: use a right hand to grab an iron roller; the other iron roller touches the lower roller and The angle is 45Â°-65Â°. The hand can effect two forces; one is positive pressure N; one is tensile force F; the effect of making these two forces is different from the rotation direction of the roller and the iron roller; and the conflicting force effect occurs On the sand skin, you can quickly remove the rust. Usually, each sand skin can be rusted by about 200 sets per hour; the hands are faster; and everyone can operate. This method has high power; low cost; no need to add equipment And personnel; it is worth a try. Third, how to avoid the iron roller rust, the condition between the roller and the special parts is necessary to constant temperature Wet. Second, it is necessary to separate the appearance of the iron roller from the air, water and corrosive products; then it is necessary to apply a thin film on the outer surface of the iron roller to complete the knot. We rely on this principle; Roll coating; the ratio is 1:2; the roller coating method is completed once; and the temperature can be rotated for 24 hours to get on the train. However, it is necessary to remove the rust before the coating of the old iron roller by using the above method; Appearance; after 24 hours of constant temperature, the coating can be applied once by roller coating.
The quality of the iron roll after passing the coating is slightly reduced; this is what we expected. The reason is that the iron roll is coated; the film is formed by the film; it can be antistatic; that is, the accumulation of hair is reduced; It can also add conflicting force to the apron; it can reduce the apron slip and the iron roller to be beaten. This way the sliver is evenly manipulated and drafted; the quality of the yarn is also improved.
Fourth, the conclusion of the bearing iron roller derusting method is simple and high power; just contact the large flat car to complete the end; human and material input is also small. If the sanding iron roller is treated with paint once; not only can extend the life of the iron roller Number; can also improve the quality of production to a certain effect. This is a two-pronged approach.
