Description
Technical field
The present invention relates to a kind of combing element that is used for spinning machine, particularly be used for the metallic card clothing of fiber combing.
Background technology
Metallic card clothing is the important combing element that is widely used on the spinning machineries such as carding machine, combing machine, it is coated on the roller or the combing plate surface of combing elements such as carding machine licker-in, cylinder, doffer, cover plate, combing plate or combing machine circle comb, to played effects such as extracting, shredding, removal of impurities, transfer and cohesion by carded fiber.
At present, the basic structure of metallic card clothing is that the card clothing sawtooth is set on the card clothing base portion, the thickness of its card clothing sawtooth is general all less than card clothing base portion thickness, thereby form the tooth root step surface in the base position at sawtooth tooth root position, this tooth root step surface is a long and narrow clinoplain or a horizontal plane, and extends along the card clothing length direction.Simultaneously also because sawtooth thickness and base portion thickness exist thickness difference, so after metallic card clothing is coated to roller or combing plate surface, form a backlash between the adjacent metal card clothing.
Because the tooth root step surface of sawtooth root is the plane, metallic card clothing is when carrying out the fiber combing, the formed air-flow of high-speed motion is always along this plane relatively, to the metallic card clothing after coating then is tangentially to flow along this face, thereby the dedusting impurities removal of fiber and the transfer of fiber between dial can only rely on rotor to rotate formed centrifugal force, and the fixing combing medium between the combing element backlash then more is difficult to shift.So on the one hand, wounded when the card clothing sawtooth, when particularly the card clothing sawtooth became crude, easier to be wounded on sawtooth, trifle in the world, staple fibre also can fill backlash, directly influenced the assorted effect of combing and expel stagnation then; On the other hand, because fiber quality extremely gently and again is subjected to the effect of air drag, it is not smooth to be easy to transfer to occur by the fiber of combing, especially fixedly combing element, the carding roller drum speed is lower or reduction, when backlash fills the combing medium, the fibre migration ability descends significantly, fiber can not shift between dial repeatedly, directly influences carding effect and product quality.
Summary of the invention
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved by this invention is that the fiber-combing metal cardcolthing that a kind of impurities removal is effective, the fibre migration rate is high is provided.
In order to solve the problems of the technologies described above, fiber-combing metal cardcolthing of the present invention is made up of card clothing base portion and the card clothing sawtooth that is positioned on the card clothing base portion; The card clothing sawtooth of equal thickness and card clothing base portion do not form the tooth root step surface on the card clothing base portion of card clothing sawtooth root; Described tooth root step surface is a wavy surface.
After adopting said structure, because being positioned at the tooth root step surface of card clothing sawtooth root is wavy surface, the formed backlash of the metallic card clothing bottom that is coated on carding roller cylindrical shell or the combing plate also is the wavy surface with heaving of the sea shape, card clothing is with roller body rotation or opposed roller cylindrical shell high-speed motion the time, air-flow in the backlash no longer is the air-flow of single direction, and produced air-flow with normal component and tangential component, and its normal component is can alternately go up down conversion direction, and this has just formed the vibration and the fluctuation of air-flow.The vibration of this air-flow and fluctuation on the one hand have desirable sawtooth cleaning action, make trifle in the world, broken seed and the easier discharge of staple fibre, and are difficult for being deposited between the backlash of metallic card clothing, thereby improve the carding effect of metallic card clothing well.On the other hand, this vibration and fluctuation have effectively improved the ability that absorbs and discharge fiber, promote the transfer of fiber, both made the card clothing sawtooth be difficult for forming wounded, promote the repeatedly transfer of fiber between dial again, improved free carding efficacy, strengthened the fiber carding effect.
Further embodiment of the present invention is, described tooth root step surface is the wavy surface that is obliquely installed, and this wavy surface extends along the card clothing length direction.Being obliquely installed of this wavy surface, and the version of extending along its length formed up big and down small completely backlash, fiber more is difficult for filling backlash, impurities removal clean the teeth and the fibre migration effect better.
