Description

Technical Field

[0001] This invention relates to the field of yarn textile technology, specifically to a composite yarn, its preparation method, and composite yarn production equipment. Background Technology

[0002] Blending is a technique that uses different types of fibers to weave yarn. Through blending, the advantages of different fibers can be combined to compensate for their shortcomings. A document with publication number CN117306047A discloses a composite yarn and its preparation method, as well as composite yarn production equipment. The composite yarn provided includes a core layer woven from a first fiber, an intermediate layer woven from a second fiber, and a sheath layer woven from a third fiber. The first, second, and third fibers are different. The intermediate layer covers the outside of the core layer, and the sheath layer covers the outside of the intermediate layer. This composite yarn can effectively combine the advantages of different fibers, and provides corresponding production equipment.

[0003] The composite yarns described above and in existing technologies lack moisture-proof and waterproof functions on their outermost layer, making them difficult to store and use.

[0004] Furthermore, in the existing technology for raw material processing in the production of composite yarns, cotton raw materials are generally transported by a cotton grabber. The existing cotton grabber conveying device usually uses a leveling rod to flatten the cotton in the annular hopper to facilitate the cotton suction. On the one hand, the leveling effect on the cotton is minimal, and on the other hand, the flattening process also has a downward squeezing effect on the cotton pile, causing the cotton to adhere and accumulate at the bottom of the annular hopper, which affects the suction operation of the cotton grabber trolley. In the existing technology, this is usually disrupted by workers, which is cumbersome. Therefore, there is a need to provide a suitable processing auxiliary mechanism to meet the needs of cotton grabbing.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-14 A composite yarn includes a fiber core layer 100, a fiber intermediate layer 200, a moisture-proof fiber layer 300, and a fiber protective outer layer 400; wherein the fiber intermediate layer 200 is disposed outside the fiber core layer 100, the moisture-proof fiber layer 300 is disposed outside the fiber intermediate layer 200, and the fiber protective outer layer 400 is disposed outside the moisture-proof fiber layer 300; the composite yarn provided by the present invention has corresponding moisture-proof properties, which facilitates its production, storage, and use.

[0022] One of the methods for preparing a composite yarn includes Raw material processing: The raw materials are transported to the spinning process by a cotton grabbing machine to process the fibers into yarns with linear density and strength; at the same time, electrospinning technology is used to directly spin functional fibers onto the yarns. Composite yarn: The fiber core layer 100, fiber intermediate layer 200, moisture-proof fiber layer 300 and fiber protective outer layer 400 are combined together by reverse twisting, covering, plying and other methods to form composite yarn; other functional fibers or yarns can also be added during the composite process to further improve the performance of the yarn. These methods can produce composite yarns with excellent properties such as elasticity, breathability and antibacterial ability to meet the higher requirements of textile products.

[0023] One of the composite yarn production devices includes: a support base 1, a rotating annular hopper 2, a cotton-grabbing cart 3, a cotton conveying pipe 4, an L-shaped support plate 5, a lifting control rod 7, and a cotton-scraping assembly. The rotating annular hopper 2 is mounted on the support base 1 and connected to the cotton-grabbing cart 3. The cotton conveying pipe 4 is mounted on the top of the cotton-grabbing cart 3. A fixed connecting plate 6 is fixed to the bottom of the L-shaped support plate 5 and is screwed to the side wall of the support base 1. A lifting control rod 7 is mounted on the top of the L-shaped support plate 5. A connecting plate 71 is fixed to the bottom of the lifting control rod 7 and is connected to the cotton-scraping assembly. The lifting control rod 7 controls the lifting and lowering of the cotton-scraping assembly. When the cotton-scraping assembly reaches the bottom of the rotating annular hopper 2, it scrapes away the material accumulated and adhering to the bottom of the rotating annular hopper 2, facilitating the cotton-grabbing cart 3's cotton-scraping operation.

[0024] Example 2: Based on Example 1, please refer to... Figures 5-14The cotton scraping assembly here includes a scraper plate 801, an air supply hose 802, a scraping auxiliary ramp 803, a receiving cavity 804, a partition plate 805, a mounting slot 806, a sealing plate 807, a mounting through hole 808, a fastening screw 809, a first air outlet assembly, an auxiliary control assembly, and a second air outlet assembly. The air supply hose 802 is symmetrically connected to the scraper plate 801, and the scraping auxiliary ramps 803 are symmetrically arranged on both sides of the scraper plate 801. A receiving cavity 804 is provided at the bottom end of the scraper plate 801, and the opening of the receiving cavity 804 is... A mounting slot 806 is provided, and a sealing plate 807 is provided in the mounting slot 806. The sealing plate 807 has symmetrical mounting through holes 808, and a placement groove is provided at one end of the mounting through hole 808. The sealing plate 807 is fixed by fastening screws 809. The top of the scraper plate 801 is provided with a threaded groove, and the scraper plate 801 is fixedly connected to the connecting plate 71 by screws. Here, a partition plate 805 is fixedly provided in the receiving cavity 804, and the partition plate 805 divides the receiving cavity 804 into two movable cavities.

[0025] Before pouring cotton into the rotating annular hopper 2, the scraper plate 801 is pushed down by the lifting control lever 7 so that the bottom end of the scraper plate 801 contacts the inner bottom of the rotating annular hopper 2. Then, cotton is put in, and the cotton grabber 3 sucks the cotton and sends it to the next processing step through the cotton conveying pipe 4. During processing, the scraper plate 801 can scrape off the cotton that has accumulated or adhered to the bottom of the rotating annular hopper 2. Furthermore, a scraping auxiliary ramp 803 is set on the side wall of the scraper plate 801. The purpose of this is twofold: firstly, to install the first air outlet component, which works in conjunction with the scraper plate 801 to prevent the scraped cotton from accumulating; secondly, the scraping auxiliary ramp 803 also guides the scraped cotton to avoid obstruction; and thirdly, the dry gas sprayed by the first air outlet component can provide a drying effect on the material.

[0026] Here, a first air outlet component is equidistantly arranged on the cotton scraping auxiliary slope 803. The first air outlet component includes a threaded cavity groove 901, an air jet groove 902, a connecting cap 903, and an auxiliary air outlet nozzle 904. The threaded cavity groove 901 is arranged on the cotton scraping auxiliary slope 803, and the air jet groove 902 is provided in the threaded cavity groove 901. The air jet groove 902 is connected to the receiving cavity 804. The threaded cavity groove 901 is threadedly connected to the connecting cap 903. The diameter of the pipe opening of the connecting cap 903 is equal to the diameter of the air jet groove 902. The auxiliary air outlet nozzles 904 are equidistantly arranged on the side of the connecting cap 903 and are inclined. The purpose of the auxiliary air outlet nozzles 904 on the side of the connecting cap 903 is to minimize the impact of cotton fibers on the auxiliary air outlet nozzles 904. The first air outlet component, while providing a drying function, also blows out accumulated cotton, reducing its accumulation and adhesion. Furthermore, the connecting cap 903 is threadedly connected to the threaded cavity 901. The connecting cap 903 is designed for easy locking and unlocking. An auxiliary air outlet nozzle 904 is provided on the side of the connecting cap 903. When loosening or tightening the connecting cap 903, the auxiliary air outlet nozzle 904 also acts as a rotating auxiliary screw, making it easier to loosen and tighten the connecting cap 903, thereby improving the ease of disassembly and assembly of the connecting cap 903. That is, when it is necessary to replace or disassemble the connecting cap 903 for cleaning, simply rotate the connecting cap 903 until it is separated from the threaded cavity 901, and then tighten the new connecting cap 903 to the threaded cavity 901.

[0027] An auxiliary control assembly is provided in the receiving cavity 804. The auxiliary control assembly includes a movable strip 1001, a rectangular ventilation cavity 1002, a flow-guiding groove 1003, a connecting pad 1004, a support spring 1005, an auxiliary baffle 1006, and a vent 1007. A support spring 1005 is fixedly installed at the top of the movable strip 1001, and a connecting pad 1004 is fixedly installed at the other end of the support spring 1005. A rectangular ventilation cavity 1002 is provided through the movable strip 1001, and flow-guiding grooves 1003 are provided at equal intervals on both sides of the movable strip 1001. The flow-guiding grooves 1003 are inclined and their positions correspond to those of the jet hole groove 902. An auxiliary baffle 1006 is provided at equal intervals at the bottom opening of the rectangular ventilation cavity 1002, and a vent 1007 is provided in the auxiliary baffle 1006.

[0028] Here, a second air vent assembly is equidistantly arranged in the sealing plate 807. The second air vent assembly includes a movable top post 1101, an auxiliary spring 1102, an auxiliary fixing plate 1103, an air vent channel 1104, and auxiliary balls 1105. The movable top post 1101 is movably inserted into the sealing plate 807, and the top of the movable top post 1101 is fixedly provided with the auxiliary fixing plate 1103. The movable top post 1101 is provided with an air vent channel 1104, which extends into the auxiliary fixing plate 1103. The auxiliary fixing plate 1103 is fixedly provided with the auxiliary spring 1102 at the end connected to the movable top post 1101, and the other end of the auxiliary spring 1102 is fixedly provided on the sealing plate 807. Here, the air vent channel 1104 is positioned corresponding to the vent hole 1007. The bottom end face of the movable top post 1101 is equidistantly fitted with auxiliary balls 1105.

[0029] In this scheme, an auxiliary control component and a second air outlet component are used in conjunction with the first air outlet component. Specifically, when the scraper plate 801 reaches the bottom of the rotating annular hopper 2, the movable top column 1101 is first compressed. The other end of the movable top column 1101 then compresses the auxiliary baffle 1006 at the bottom of the rectangular ventilation cavity 1002, thereby compressing the movable strip 1001. This causes the flow-guiding groove 1003 on the side of the movable strip 1001 to align with the air jet groove 902 in the scraper auxiliary ramp 803. At this point, the movable top column... 1101 retracts into the receiving cavity 804. The dry gas input from the gas supply hose 802 enters the receiving cavity 804, then enters the rectangular ventilation cavity 1002 in the movable strip 1001, and then enters the jet hole groove 902 from the flow connecting groove 1003, and finally is ejected from the auxiliary air outlet nozzle 904 on the side of the connecting pipe cap 903. The function of setting the auxiliary ball bearing 1105 at the bottom of the movable top column 1101 is to minimize the frictional damage to the movable top column 1101 when it is under pressure.

[0030] When the scraper plate 801 needs to be raised, the lifting control lever 7 raises the scraper plate 801. At this time, the pressure on the movable top column 1101 is released, and the movable top column 1101 resets. At the same time, the movable strip 1001 resets under the action of the support spring 1005, thereby causing the flow channel 1003 and the jet hole channel 902 to be misaligned. The movable strip 1001 misaligns with the jet hole channel 902. At this time, drying gas can continue to be input into the scraper plate 801 through the air supply hose 802. The gas enters the receiving cavity 804, then reaches the rectangular ventilation cavity 1002, and finally is ejected from the air outlet channel 1104 in the movable top column 1101 through the ventilation hole 1007 on the auxiliary baffle 1006. This also has a drying effect on the material in the rotating annular hopper 2. When the scraper plate 801 rises, the supply of drying gas can also be stopped, which has better working flexibility.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
