The disclosed rotor spinning carding roller card clothing can reduce the damage to raw material fibers during rotor spinning combing.
The card clothing improves the fiber carding transfer effect and reduces card clothing fatigue through different tooth shape designs of the front working face of the card clothing teeth. However, there are still problems such as poor carding effect, and large damage to fibers and card clothing for fiber raw materials such as bundle fibers, hard blocks, and offcuts with high nep content.
Disclosure of Invention
The invention aims to solve the problems in the prior art, provides a carding wire with finishing teeth, solves the problem of difficult carding caused by high contents of bundled fibers, hard lumps and neps of fiber raw materials, and protects the carding wire teeth to the maximum extent.
In order to achieve the above purpose, the invention adopts the following technical scheme:
The carding clothing with the finishing teeth comprises a base part and tooth parts arranged above the base part, wherein the tooth parts comprise carding teeth, and the back of each carding tooth is provided with one finishing tooth;
the front of each finishing tooth is in transitional connection with the back of the carding tooth where the finishing tooth is positioned, and the back of each finishing tooth is in transitional connection with the front of one carding tooth at the back of the carding tooth where the finishing tooth is positioned;
The distance between the tooth tip A of each finishing tooth and the lower surface of the base is h1, the distance between the tooth tip B of each carding tooth and the lower surface of the base is h7, and h1 is equal to h7;
the working angle of each finishing tooth (the angle between the tangent line of the tooth front at the tooth tip and the perpendicular line of the lower surface of the base) is alpha 3, and the working angle of each carding tooth is alpha 4, wherein alpha 3 is smaller than alpha 4.
In order to cope with the damage of the bundle blocks, dead knots and foreign matters in the leftover fibers to the needle teeth, and simultaneously improve the carding effect of the leftover fibers containing excessive neps, short piles and impurities, the special-designed finishing teeth are additionally arranged at the back of the needle teeth of the conventional card clothing, the bundle fibers, hard blocks, neps and the like are primarily opened and directionally finished through the finishing teeth, and then the fibers after the pre-opened finishing are further carded through the carding teeth, so that the carding degree is increased, the short piles are reduced by soft carding, the transfer of the neps, the short piles and the foreign matters is enhanced, the good carding effect is realized, and the aim of reducing the damage of the needle teeth is fulfilled.
The finishing teeth are attached to the tooth back surfaces of the carding teeth, and are designed mainly aiming at the characteristics of serious fiber entanglement, more fiber bundles, fiber fatigue and high short velvet, and the finishing teeth have the functions of pre-loosening cotton bundles and neps, enhancing directional carding and increasing the capability of removing impurities and transferring short velvet before carding the teeth.
The distance between the tooth tips B of the finishing teeth and the carding teeth and the lower surface of the base adopts a contour design, so that the finishing teeth and the carding teeth can obtain the same carding gauge of the cover plate, hard lumps, neps, short piles and sundries in the leftover fiber layer are promoted to be more easily held by the cover plate in a tight gauge state, thereby realizing the efficient transfer of falling sundries, and meanwhile, the contour design can promote the finishing teeth to fully participate in the opening, impurity removal, pre-carding and pre-finishing processes of the fiber layer, the carding strength of the carding teeth is reduced, thereby realizing flexible carding and preventing the fatigued fibers of the leftovers from further damaging.
The working angle of the finishing teeth is smaller than that of the carding teeth, and the working angle of the finishing teeth is smaller, so that the fiber cannot be damaged due to weaker holding stress of the finishing teeth, the smaller working angle is beneficial to throwing and removing impurities and transferring the fiber on the raw fiber materials of the finishing teeth, the enlarged working angle of the carding teeth is beneficial to improving the holding effect on the fiber, carding is enhanced, and a combined carding mode formed by the finishing teeth and the carding teeth can realize good carding effect on the raw fiber materials with high impurity content and high content, hard lumps, high neps and the like, and meanwhile, the damage to the fiber and card clothing in the carding process is reduced.
The carding clothing with the finishing teeth has the advantages that the included angles between the tangent line of the front face of each finishing tooth at each position and the lower surface of the base part are gradually increased along the direction from the tooth tip to the tooth root, the movement and transfer capacity of fibers to the tooth tip can be improved, the fibers are prevented from sinking into tooth gaps, the anti-winding capacity of the needle teeth is improved, meanwhile, the distance from the tooth tip to the tooth bottom of the finishing area is smaller, the needle gap fiber holding amount is less, the needle face load is light, and the needle tooth damage is reduced.
The carding wire with the finishing teeth has the h1 of 1.8-2.0 mm.

The arrangement teeth adopt a larger tooth rake design, and are beneficial to throwing and removing impurities and transferring fibers while grabbing and loosening fibers such as offal and the like, so as to achieve the aim of arranging raw materials with high impurity content, bundle fibers, hard lumps and nep content. If the fiber layer is carded and transferred between the cylinder and the cover plate, dead knots of leftover fibers and fiber bundle blocks are easier to slide to the cover plate along a tangential working surface under the condition that the finishing teeth are stressed and blocked, so that the needle teeth are prevented from being broken due to overlarge tearing force of the card clothing; and for most useful but disordered fibers, the effective finishing and pre-carding of the finishing teeth gradually enter an ordered state, the carding load of the carding teeth is reduced, and conditions are created for further carding of the carding teeth. The arrangement teeth adopt a larger tooth tip angle design, so that damage to needle teeth caused by leftover fiber bundles, dead knots, impurities and foreign matters can be reduced.

According to the carding wire with the arrangement teeth, the distance h2 between the tooth tip A of each arrangement tooth and the L1 is 0.12-0.18 mm along the direction parallel to the perpendicular line of the lower surface of the base, and the distance h6 between the tooth tip A of each arrangement tooth and the L2 is 0.35-0.45 mm.
