Bearing iron roller cleaning and rust
Iron roller bearing is necessary for the yarn spinning mill thickness textile equipment. It and epithelial match into assembly, apron, with roller apron in the jaw, to grip sliver, is one of the drafting device. It is passive in the drive. Its direct effect on yarn quality can be good or bad. But its processing quality is different from that of roller. Because between the roller of the roller production maintenance is complete. And it only between roller is responsible for the maintenance, manufacturing quality depends entirely on spinning machine factory. Generally we only strengthen the purchase acceptance, quality is no problem. For its maintenance quality mainly include: regular cleaning, refueling, radial, axial indelible check, rotary and beating examination work requirements. For the iron roller surface rust and dung GeChang were difficult, often neglect to do or not do less. For manual cleaning is so annoying, but more difficult to prevent rust. The following is our factory made a simple introduction on how to solve this problem.
A, the reason of rust Rusty iron roller to be in contact with water or chemicals, such as air condition, can be created. While it between the roller and designed a maintenance between rotates, often to meet large variation of the temperature and humidity. Between the roller because of our factory production and designed a without air conditioning, even if it has difficulty in normal control as well as air conditioning. Plus iron roller refueling when cleaning, because of the cleaning solution is acidic, (because of the new circle is the rubber factory factory after acid treatment, and generally the new circle between roller is not through neutralization processing and directly on the use of, so the new delineating acidic.) Once encountered when humidity is big, will cause large quantities of iron roller rust, shorten the life time in a long iron roller, but also influence the yarn quality.
Second, the quick cleaning By easy bearing iron roller rotation, hand hold, with iron ore skin remove rust is more difficult, and low efficiency. We use hydraulic roller pressure circular machine (A812 roller pressure circular machine can also be) under the first root of roller, coating 2 0 # iron ore. Burning on the adhesive plaster inside and outside the left, middle and right three fixed can. Burning on the fixed direction with the cylinder rotate in opposite directions, adhesive plaster specifications about 80 x 10, a total of 6, can be fixed a burning on. During operation, motor starting on the roller drive up.
Method is: with the right hand holding a head of iron roller, on the other side under the iron roller contact roller and 45 °, 65 ° Angle. Hand works two forces, a positive pressure for N, one for the pulling force F, made these two forces and roller and iron roller rotation direction is different, the effects of the friction force and on burning on quick descaling. General operating each burning on one hand around 200 sets per hour can derusting, hands quickly, but everyone can operate. This method is of high efficiency, low cost, do not need to increase equipment and personnel, it is worth a try. Three, how to prevent the iron rollers rust One is between the roller and designed a conditional must be constant temperature and humidity.
Second, must take iron roller surface separate from air, water and corrosion product, then in iron roller surface coated with a thin layer of protective film. According to this reason, we use local materials, which USES roller coating, ratio of 1:2, a complete with roller coating method, and the constant rotation can be get by using 24 hours a day. But the old iron roller before coating must use the above method in removing impurity, derusting and metal cleaner clean surface, constant temperature after 24 hours to dry, can be coated paint a roller coating method. After coating of iron roller yarn quality fell slightly more, this is what we want. The reason I think is iron roller after coating, it produces the protective film, can antistatic, which reduced cost of MAO's accumulation, but also increase the friction of aprons, can reduce the apron slide and iron roller and beating. This article combs the get the uniform control and drafting, yarn quality is improved. Four, conclusion bearing iron roller cleaning method is simple and high efficiency, need only in combination with size flat wagon, manpower input is lesser also. If the sanding iron roller coating processing time, not only can prolong the life of the iron roller, also can improve the quality of product to a role. This is the way to every second to.
