Bearing iron roller is spinning factory must be textile equipment of yarn degree. It and epithelial circle, aprons frame made up with a combination, the next aprons with Laura form a clamp mouth, a mouth to hold the function, is one of the components of drafting.
 
In the transmission in the it is passive one. It when the stand or fall of yarn quality can be up direct action. But its processing quality is different from PiGun. Because of the PiGun making maintenance have PiGun fulfilling. But it, PiGun only responsible for maintenance work between, manufacturing quality depends entirely on the spinning factory.
 
Generally we want to strengthen purchase acceptance, the quality is not a problem. For its maintenance quality mainly has: regular cleaning, come on, radial, axial indelible check, rotary's work requires a check, etc. And for iron roller surface rust and NianJieWu problems are difficult to deal with GeChang, often by oversight don't do or less. For manual derusting is so annoying, to prevent rust is more difficult. Here is our factory of how to solve this problem, a simple introduction.
 
A, the cause of rust
 
Iron roller in contact with water or rust chemicals, such as air condition, can be created. And it PiGun in between and designed a rotating between maintenance, often to meet the temperature and humidity changes greatly. Because of our factory PiGun production and designed a room without air conditioning, the afraid have air conditioning and difficult normal control. Plus iron roller refueling when cleaning, for cleaning solution is acidic, (for new circle is rubber factory after acid treatment factory, and PiGun after the general new circle of between is not pass through and processing, so the car use directly new delineated become acidic.) Once encountered humidity is big, iron roller caused mass rust, a long time, the iron roller shorten life, but also affect yarn quality.
 
Second, the fast derusting method
 
For iron roller bearings to rotate, easily hold hands, skin with iron ore manual derusting more difficult, and low efficiency. We use PiGun hydraulic pressure circular machine (A812 PiGun pressure circular machine also can) first roots roller, coated two zhang 0 # iron ore skin. ShaPi using a plaster on it inside and outside of the left, right, three fixed can. ShaPi fixed with roller rotation direction in opposite directions, a plaster on it specification is about 80 x 10 of article 6, can be fixed a ShaPi. When operating, starting motor is up on pressure roller can be carried out on. The method is: use the right hand holding a head of iron roller, the other a head of iron roller contact roller and under 45 ° to 65 ° Angle. Hand can effect two force, a positive pressure for N, one for pulling force F, made it two of forces and roller and iron roller rotation direction is different, and produces friction function of the ShaPi can fast derusting. Common single hand operation ShaPi each hour 200 sets can be placed around, both hands is faster, and everyone can operate. This method is of high efficiency, low cost, do not need to increase equipment and personnel, is worth a try.

Three, how to prevent iron roller rust
 
One is the only thing PiGun room and have between conditions must be constant temperature and humidity. 2 it is must take iron roller surface with air, water, and corrosive apart, that is about to roll in iron coated with a thin film to achieve. We according to this truth, use local materials, which is the PiGun coating, the matching for 2-1, with roller coating method once completed, and constant temperature spin 24 hours can get on the car use. But the old iron roll in besmear before using the above method must be placed impurity, and metallic detergent.this clean surface, constant temperature 24 hours after dry, can besmear of using the roll with a coating.
 
After the iron roller coating yarn quality fell slightly more, this is really what we hope. The reason I think is iron roll after the coating, it generated protective film, can antistatic, which reduced flower in the accumulation of MAO, and also can increase friction of apron, can reduce the skin smooth and iron roll a circle at play. This article comb got even control and drawing, yarn quality is improved.
 
Four, endnotes
 
Bearing iron roller derusting method is easy and high efficiency, need to finish with size lockstitcher, manpower material resources into lesser also. If the sand iron roller coating of light with processing time, not only can prolong the life of iron roller, for improving product quality to some effect. This is the method of every two is.
