Detailed Description

The present invention will be described in further detail with reference to the following examples and the accompanying drawings so that those skilled in the art can practice the invention with reference to the description.

In the description of the present invention, the terms "inside", "between", "surface", "inner cavity", and the like indicate orientations or positional relationships based on those shown in the drawings, only for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 5, the present invention provides a flat clothing for different fiber flexible carding, including a plurality of clothing strips 1, the plurality of clothing strips 1 are arranged on a flat 3, the clothing strips 1 include a clothing fixing groove 11 and a clothing 12 fixed in the clothing fixing groove 11, the clothing 12 includes a rubber pad base material 121 accommodated in the clothing fixing groove 11 and a plurality of crochet hooks 122 inserted in the rubber pad base material 121, the clothing strips 1 further include: the first electric heating ceramic piece 13 capable of adjusting and controlling the temperature is arranged between the card clothing fixing groove 11 and the card clothing 12, the bottom of the crochet hook 122 is connected with the first electric heating ceramic piece 13, and the crochet hook 122 is in a sine wave shape structure;

the temperature of the first electric heating ceramic piece 13 is adjusted, the first electric heating ceramic pieces 13 with different temperatures provide different heats for the card clothing 12, the first electric heating ceramic piece 13 is connected with the heat conduction card wire processing module to realize multifunctional integrated design, including self-temperature control, directional heat release, alarm display, protection and the like, so that the aims of temperature control automation, energy consumption minimization, convenient and safe operation are achieved, the temperature of the first electric heating ceramic pieces 13 is adjusted and combed according to the characteristics of different fibers, the combing efficiency is effectively improved, the combing quality is improved, and the fiber damage is reduced;

the first electric heating ceramic plate 13 heats the bottom of the crochet hook 122, the crochet hook 122 has obvious heat transfer effect, the heat transfer from the bottom of the crochet hook 122 to the top of the crochet hook 122 is realized by heat conduction, the bottom heat transfer efficiency is highest, the top heat transfer efficiency is lowest, and the hierarchical temperature-changing crochet hook 122 from the bottom to the top is formed. When the fibers contact the heated crochet hook 122 in the carding process, the glass transition temperature can be instantly reached, so that the rigidity of the fibers is greatly reduced, the flexibility of the fibers is increased, the carding is more facilitated, and the fiber damage and the machine part abrasion caused by forced carding of the fibers by mechanical force are reduced. When fibers with different lengths enter the carding machine, the fibers sequentially contact different parts of the crochet hook 122 according to the fiber lengths, and due to the fact that the temperatures of the different parts are in a gradient mode, targeted softening treatment on the fibers with different lengths in the same batch can be achieved, the longer the fiber length is, the more easily the fibers are subjected to mechanical damage in the carding process, and the longer the fibers are, the more easily the longer the fibers contact the position, close to the bottom, of the heating crochet hook 122, with higher temperature control, the more effective softening treatment can be achieved; the closer the shorter fibers are to the top of the crochet hook 122, the lower the softening degree is, and certain fiber rigidity is effectively maintained, so that fiber deposition and noil are reduced. Meanwhile, the fiber can be effectively graded, softened and carded by heat for different kinds of blended chemical fibers, and the fiber can be carded by heat in multiple stages according to the glass transition temperature and the fiber main body length of different kinds of chemical fibers.

The crochet hook 122 is in a sine wave-shaped structure, so that the range of uncontrollable fibers in a drafting zone is reduced, the quantity of disordered fibers is greatly reduced, and the multi-direction coordination co-construction holding force is realized. The sinusoidal surface structure enhances the transverse control of the fibers, the sinusoidal wave peak accurately partitions the fibers with different lengths, targeted heat carding can be carried out due to different temperature control of each heat transfer area, and the sinusoidal surface increases the heat treatment contact area of the fibers. Meanwhile, the fibers are subjected to the pressure action of the sinusoidal curved surface, and the fibers orderly slide along the sinusoidal wave trough structure, so that effective control in the carding process is realized; the sine wave crest structure is embedded into the fiber to form secondary carding and zoning effects on the fiber bundle. Aiming at the blending of different fibers, the crochet hook 122 with the string structure can control the movement of floating fibers more perfectly, and can be divided into different chemical fibers for heat treatment softening, thereby effectively improving the straightening parallelism of the fibers, optimizing the fiber carding and reducing the fiber damage. The fiber control capability can be increased in the drafting process, the fiber motion fluctuation is reduced, the fiber speed change becomes stable, the speed change points are concentrated, the shift deviation is reduced, the additional unevenness in the drafting process is reduced, and the resultant yarn evenness is improved.
