The bearing iron roll is spins the factory thick spun yarn to have the textile equipment.It and on the leather ring, the leather ring frame matches the assembly, forms a mouth of the tongs with the Roller dermis circle, plays to the cotton sliver grasps holds the role, is one of drafts parts.In the transmission it is by the moving parts.When its quality becomes the gauze quality to be possible to get up the direct action.But its processing quality is different with the top roller.Because the top roller manufacture maintenance all has between the top roller to complete.But it, between the top roller only is responsible for the maintenance, the manufacture quality is decided completely in spins the equipment plant.We the enhancement inventory approval, the quality is not a problem so long as generally.Mainly has regarding its maintenance quality: The regular clean, refuels axial, the radial direction, obliterates the inspection, rotates hits work requirements and so on the inspection.But rusts to the iron roll surface with the caking question various factories all felt difficult to process, often is neglected does not do or little does.Because eliminates the rust too to be really bothersome manually, must prevent rusts is more difficult.How does below solve this problem on my factory to make a simple introduction.
First, rusty reason
The iron roll rusts must in physical conditions and so on contact water or chemical, air, can produce.But it and maintains revolving specially when the top roller between, frequently must meet the humiture the sweeping change.Because my factory top roller manufacture and does not have the air conditioning specially, that feared has the air conditioning also difficulty normal control.When in addition the iron roll refuels the clean, because the cleaning liquid also is acidic, because (the new circle is the rubber factory leaves the plant after the acid treatment, but between the top roller does not pass through to the new circle neutral processing to board directly generally the use, therefore selects newly assumes the acidity.When) meets the humidity in a big way, creates the iron roll mass to rust, a time long iron roll loss of life, but also must affect the gauze quality.
Second, eliminates the rust law fast
Because the bearing iron roll easy to revolve, the hand difficulty grips, eliminates the rust with the hard sand skin to be difficult manually, the efficiency lowers.We use the hydraulic pressure type skin to roll the circle machine (the A812 skin rolls circle machine also to be possible) the first under drum, the gable two 0# iron sand skin.The sand skin uses the adhesive plaster inside and outside each left, middle and right three points fixed then.The sand skin fixed direction is opposite with the drum hand of rotation, the adhesive plaster specification for 80×10 altogether 6, may fix a sand skin approximately.When operation, the starting motor namely on drag roll raises may carry on.The method is: Grips an iron roll with the right hand, under another iron roll contact the drum combines to make or become 45°-65° the angle.The hand may affect two strength, one for pressure N, one is pulling force F, makes these two strength the function and the drum and the iron roll hand of rotation is different, but produces the friction action of force then fast eliminates the rust on the sand skin.General one-handed operation each sand skin each hour may except rust about 200 sets, both hands are quicker, moreover everybody may operate.This method efficiency is high, the cost is low, does not have to increase the equipment and the personnel, is worth trial one.
Third, how prevented the iron roll rusts
One is between the top roller and has the condition to have specially the constant temperature constant humidity.Two, must the iron roll surface with the air, the water and the corrosion separates, that must spread thin protective film in the iron roll surface to realize.We according to this truth, uses makes use of local materials, namely with the top roller coating, the allocated proportion is 1:2, with rolls spreads law one time to complete, and the constant temperature revolves for 24 hours then to board the use.But the old iron roll must use the above method in front of spreading except the rust except mixed, and with metal cleansing agent clean surface, after constant temperature 24 hours dry, then uses rolls spreads the law to spread coating one time.
After the process coating iron roll becomes the gauze quality many to have the drop slightly, this really is we hoped.Its reason I want to be the iron roll after the coating, it produces protective film, then anti-static electricity, namely reduced cotton waste agglomeration, also may to the rubber or plastic rings increase friction force, then reduce the leather ring to remain slippery with the iron roll hits.Like this combed the strip to be under the even control and the drafts, became the gauze quality also to enhance.
Fourth, conclusion
The bearing iron roll easily eliminates the rust law both and the efficiency to be high, only must unify the big and small flatcar to complete, the manpower physical resource investment is also small.If processes the polishing iron roll with the coating one time, not only can lengthen the iron roll the life, but also can to the product quality enhancement to certain function.This is a method which two results in at one fell swoop.
