Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and more specifically, to a wool opening and impurity removal device. Background Technology
[0002] Existing cashmere opening and carding equipment includes a feeder, feed roller assembly, licker-in roller, cylinder, doffer, and cutter connected sequentially from front to back. The cylinder typically has 2-3 sets of identical work roller assemblies spaced circumferentially. Each work roller assembly includes a stripping roller and a working roller connected together; the work rollers are generally metal needle-cloth rollers. During the carding process, the three sets of work rollers apply the same degree of carding force (i.e., the same hardness) to the wool. The damage to the fibers increases as the rollers move further back in the process, with the third set of work rollers causing the most severe fiber damage, leading to a decline in wool quality.
[0003] In addition, the invention patent with announcement number CN105350117A discloses a coarse and fine fiber combined opening and coarsening machine. In this machine, the weeding knife is equipped with a weeding box for collecting the weeds knocked off by the weeding knife. The weeding knife is roughly L-shaped with a large opening. The knocked-off weeds fall into the weeding box. With the slight wind generated by the rotation of the roller, the weeds are easily blown out from the opening of the weeding box and re-rolled into the wool fibers.
[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figure 1 As shown, a preferred embodiment of the present invention provides a wool opening and impurity removal device, which includes a wool feeder 1, a feed roller assembly 2, a licker-in roller 3, a cylinder 4, a doffer 5, and a cutter 6 connected in sequence from front to back.
[0027] The wool feeding machine is an automatic wool feeding machine, and its specific structure is based on existing technology and will not be described in detail here. The feeding roller assembly 2 includes four feeding rollers 7 arranged in a square. Wool fibers are fed in through the feeding roller assembly 2 and transferred to the cylinder 4 through the licker-in roller 3.
[0028] The cylinder has a first working roller assembly, a weed and weed removal device, a second working roller assembly, and a third working roller assembly arranged sequentially from front to back around its four circumferences.
[0029] The first working roller assembly includes a first stripping roller 8 and a first working roller 9 connected from front to back. The first working roller 9 includes a first roller cylinder, and a plurality of metal comb needles are evenly and obliquely distributed on the surface of the first roller cylinder, such as... Figure 2 As shown, the metal comb needles include a cylindrical body with a conical top. The metal comb needles are relatively coarse and sparsely arranged on the surface of the first roller. The first working roller assembly is mainly used for preliminary hard combing of wool fibers.
[0030] The weeding and weeding device includes a weed cutter 10, a weed collection box 11, and a weed cleaning mechanism. The weed cutter 10 is arranged along the cylinder 4 axis. The weed collection box 11 includes a U-shaped trough with an end plate at one end and an opening at the other end. The weed collection box 11 is located in front of the weed cutter 10, arranged along the cylinder 4 axis, with the trough opening facing the weed cutter. The weed cleaning mechanism is located inside the weed collection box 11. Specifically, the weed cleaning mechanism includes a drive pulley, a driven pulley, a circular conveyor belt, and scrapers. The drive pulley is located near the end plate of the weed collection box and is driven by an external drive device. The driven pulley is located near the port of the weed collection box. The circular conveyor belt is located between the drive pulley and the driven pulley. There are at least two scrapers spaced apart on the surface of the circular conveyor belt. As the scrapers follow the circular conveyor belt, they can promptly clean the weeds and debris in the weed collection box 11 from the port to the outside of the machine.
[0031] The main body of the grass and debris collection box 11, namely the U-shaped trough, adopts a U-shaped design, which can effectively prevent grass and debris falling into the grass and debris collection box 11 from being blown out from the opening of the grass and debris collection box and re-rolled into the wool fibers.
[0032] The second working roller assembly includes a second stripping roller 12 and a second working roller 13 connected from front to back, such as Figure 3 As shown, the second working roller 13 includes a second roller and a serrated strip. The serrated strip is spirally arranged on the surface of the second roller, and the tips of the teeth on the serrated strip are inclined upwards. The second working roller assembly is mainly used for further opening and combing of wool fibers.
[0033] The third working roller assembly includes a third stripping roller 14 and a third working roller 15 connected from front to back. The third working roller includes a third roller cylinder, the surface of which is covered with elastic needle cloth. The elastic needle cloth includes a base cloth, on which a plurality of steel needles are evenly distributed, and the tips of the steel needles have an inclined surface. Figure 3 As shown, the steel needles are finer and more flexible, with an outer diameter smaller than that of the metal comb needles. The steel needles are arranged more densely on the surface of the third roller, with a higher density than that of the metal comb needles. The third working roller assembly is mainly used for the flexible combing of wool fibers.
[0034] The wool fibers are combed gradually from hard to soft and from coarse to fine through the three working rollers on cylinder 4, thereby reducing damage to the wool fibers.
[0035] Furthermore, on the cylinder 4 circumferentially upward, a first wind deflector roller 16 is provided on the front side of the first working roller assembly, and a second wind deflector roller 17 is provided on the rear side of the third working roller assembly.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
