Technical Field

The present disclosure relates to the field of textile machinery. In particular, the present disclosure relates to a fiber material opening apparatus used in a scutching process (blow room) of a spinning mill and a method thereof.

Background

The background description includes information that may be useful for understanding the present invention. It is not an admission that any of the information provided herein is prior art or prior art to any publication that is related to, or that is explicitly or implicitly referenced by, the presently claimed invention.

Machines used in the opening scutching process of spinning mills are well known in the art. When bales of man-made or artificial fibre material arrive at the spinning mill, various operations are performed on these fibre materials in the open-picking process to make these materials suitable for spinning. Typically, operations performed in the open-picking process include: opening bales by extracting clumps of densely packed fibers, further opening clumps of fiber material into smaller clumps or bunches (tufts), mixing or blending different types or grades of materials, trash removal of fiber materials, dust removal and uniform feeding of materials to a carding machine.

The opening and scutching equipment consists of a series of different machines to perform the above-mentioned operations. Typically, each machine includes a different size licker-in or various types of mechanical cotton-picking beaters. Natural or artificial fibre material received in a highly compacted form, i.e. a bale, is gradually opened into smaller and smaller lumps through several stages. During this process, foreign matter loosened from the material is separated from the fibers. As the size of the clumps/clusters becomes smaller at each subsequent stage, the required processing intensity requires different machine configurations for the different stages.

However, as in conventional machines, handling the fibrous material with mechanical components such as lickerins or scutchers can result in a large number of high quality long fibers breaking, resulting in a loss of material quality. In addition, the conventional process has other disadvantages. For example, a large number of unopened or partially opened lumps pass together with the opened material, so that a large number of foreign bodies remain in the end product. Since foreign materials hidden inside the fiber bundle cannot be eliminated, it is necessary to remove these foreign materials as waste together with the fiber bundle, resulting in a loss of good-quality-length fibers. If a greater number of beater points are to be used to open all of the fibre tows, the increased processing can result in increased fibre breakage and waste. Therefore, three to four tapping points are generally considered as boundaries of the most typical setting.

Accordingly, there is a need for an improved method and apparatus for opening fibrous material in an opening picking process that replaces the conventional methods and apparatus using licker-in or scutcher.

Detailed Description

The following are specific embodiments of the present disclosure depicted in the accompanying drawings. The details of the embodiments are set forth in order to provide a clear conveyance of the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the disclosure as defined by the appended claims.

Each of the appended claims defines a separate invention, which for infringement purposes is recognized as including equivalents to the various elements or limitations specified in the claims. Depending on the context, in some cases, all references below to the "invention" may refer to certain specific embodiments only. In other instances, it will be recognized that references to "the invention" will refer to subject matter recited in one or more, but not necessarily all, of the claims.

Various terms are used herein. To the extent a term used in a claim is not defined, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

Embodiments described herein relate to opening tufts or clumps of fibrous material, such as cotton or other man-made fibrous material, in an opening process at a spinning mill. In spinning mills, the fibrous material is received in a highly compressed state in the form of bales (bales). When material is removed from a bale, such as by using a bale opener, the material may appear in the form of lumps and clusters and is therefore unsuitable for use in spinning operations. Furthermore, the material may also contain foreign bodies, such as seeds, leaves, dust, etc., which need to be separated before feeding the fibre material to the spinning machine.

Thus, the mass/mat of material is subjected to a series of operations to loosen the mass/mat so that the foreign bodies are separated, thereby preparing the fibrous material for spinning.

Fig. 1 illustrates a schematic diagram showing a typical arrangement for loosening lumps/clusters of fibrous material and separating foreign matter therefrom. As shown, conventional machines and methods for bulking clumps/tufts of fibrous material are based on a lickerin roll, such as roll 102, which bulks the fibrous material by pulling/beating the spiked tufts 104 fed to the roll 102. As shown, as the tufts 104 become loose, the foreign matter 106 is separated and falls off. The loose fibrous material 108 is transported away by suction using compressed air 110.

Conventional machines and methods such as that shown in fig. 1 can result in a large number of high quality long fibers breaking, resulting in a loss of material quality. In addition, a large amount of unopened or partially opened mass passes through with the opened material, thus leaving a large amount of foreign matter in the final product. Since foreign matter hidden inside the fiber bundle cannot be eliminated, these unopened pieces/clumps need to be removed as waste, resulting in a loss of good-length fibers.

Embodiments of the present disclosure provide an apparatus and method for opening fibrous material that overcomes the disadvantages of conventional methods using licker-in and/or mechanical scutcher. In one aspect, the disclosed method and apparatus for implementing the proposed method uses bursts of pressurized gaseous fluid instead of licker-in and/or mechanical grab beater bars, which results in reduced fiber damage or breakage, reduced waste of premium fiber, and more efficient foreign matter removal.

With reference to fig. 2A and 2B, fig. 2A and 2B illustrate an exemplary schematic representation of the proposed apparatus for opening lumps and clusters of fibrous material by means of a side view and a top view, respectively, the disclosed apparatus 200 comprising: at least one chamber 202, the at least one chamber 202 having an opening 204 for feeding fibrous material; and at least one nozzle 206, the at least one nozzle 206 positioned adjacent to the opening 204 such that a controlled jet of pressurized gaseous fluid from the at least one nozzle 206 is directed toward the mass 210 of fibrous material. The controlled jet of pressurized gaseous fluid impacting the mass 210 opens the mass 210, thereby producing smaller and more opened fiber clusters.

In one aspect, the loose tufts may be transported to the next stage by suction or any other means.

(not shown here)

In one embodiment, the gaseous fluid used may be air, which is readily available and inexpensive to compress. In particular, equipment for compressing air is readily available and is often part of an opening and picking facility such as for cotton bale opening machines. Thus, the source of pressurized gaseous fluid may be an external source, such as a compressed air source of an opening facility, or may be built into the apparatus 200. In an alternative embodiment, the source of pressurized gaseous fluid may be a combination of an external source and an internal source.

In one embodiment, the pressurized gaseous fluid may be a mixture of air and gas.

In one aspect, the fiber material opened by the proposed apparatus 200 may be any one or combination of natural and man-made fibers.

In one aspect, the controlled jet of pressurized gaseous fluid may burst for a short duration, and the short duration burst may be achieved by a control mechanism 208 disposed in the passage for the gaseous fluid, as shown.

In one aspect, the at least one nozzle may include a plurality of nozzles 206 arranged in one or more rows of nozzles, and may be configured to direct more than one jet from a single or multiple directions toward the clumps/clumps 210 of fibers, either simultaneously or in a sequential manner.

In one embodiment, the nozzle 206 may be fixed or movable to direct the jet of air in a horizontal plane or a vertical plane or both to direct the jet in a single or multiple directions simultaneously or in a sequential manner.

In one aspect, the air jets may interact with the clumps/clumps of fibrous material by directly impacting and penetrating the clumps of fibrous material, thereby spreading the fibrous material into a larger space to open the clumps, or may interact by pulling fibers from the clumps due to the pulling action of compressed air flowing through the clumps. In either case, the explosive action of the air jets results in better opening and distribution of the fibrous material with reduced damage or breakage of the fibers. In another aspect, the separation of the fibrous material causes any foreign matter captured by the fibers to be loosened, resulting in cleaning of the fibrous material.

As can be seen, the proposed apparatus is characterized in that there is no mechanical beating of the mass of fibrous material to open the mass, thus minimizing the breakage of the fibers.

In one aspect, the at least one chamber 202 may be shaped to allow for the dispersion of the opened fibrous material into a larger volume. As shown in fig. 2B, the chamber 202 may have a diverging shape to provide more room for loose fibrous material.

One aspect of the present disclosure relates to a method for opening clumps and clumps of fibrous material received from a bale opener. As shown in fig. 3, at step 302, the proposed method 300 involves feeding a mass of fibrous material, such as the mass of fibrous material 210 shown in fig. 2A and 2B, through an opening, such as opening 204 (shown in fig. 2A). Step 304 of method 300 may direct a controlled jet of pressurized gaseous fluid from at least one nozzle, such as nozzle 206 shown in fig. 2A and 2B, toward the mass of fibrous material 210 fed through opening 204. In one aspect, the controlled jet of pressurized gaseous fluid upon impacting the mass 210 may cause the mass 210 to open.

In one aspect, the proposed method further comprises a step 306 of controlling the jet of pressurized gaseous fluid to produce a burst of short duration. The short duration bursts may be generated by a control mechanism, such as the control mechanism 208 shown in fig. 1A and 1B, which is disposed in the passage of the gaseous fluid as shown.

In one embodiment, there may be multiple nozzles 206 arranged in one or more rows of nozzles, and may be configured to direct more than one jet from a single or multiple directions to the clumps/clumps of fibers 210 simultaneously or in a sequential manner.

In one embodiment, the method may comprise the steps of: the nozzle 206 is moved to direct jets of pressurized gaseous fluid in a horizontal plane or a vertical plane or both to direct the jets in a single or multiple directions simultaneously or in a sequential manner.

Accordingly, the present disclosure provides an apparatus and method for opening a tuft/mass of fibrous material using a compressed gaseous fluid to eliminate licker-in and/or mechanical grasper beater, thereby overcoming the disadvantages of conventional methods and machines. The proposed method and the apparatus for implementing the proposed method reduce waste of quality fibers, prevent breakage of fibers, and remove foreign substances more effectively.

While the foregoing is directed to various embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the appended claims. The invention is not limited to the embodiments, versions or examples described, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to those having ordinary skill in the art.
