Description

Technical Field

[0001] This utility model relates to the technical field of textile spinning equipment accessories, and in particular to a jet vortex spinning twister for viscose-nylon blended core-spun yarn. Background Technology

[0002] Viscose-nylon blended core-spun yarn uses nylon filament as the core and viscose staple fiber as the sheath, combining the high strength of nylon with the skin-friendly properties of viscose. It is widely used in the field of high-end fabrics. Air-jet vortex spinning, with its high-speed yarn forming advantage of 800-1200m / min, has become the mainstream production process for this type of yarn. The twister, as the core component of air-jet twisting, is designed for the efficient twisting of short fiber bundles. Its core structure consists of a vortex nozzle, a spiral air channel, a yarn guide channel, and a negative pressure generating interface. During operation, a high-pressure airflow forms a high-speed rotating vortex field in the nozzle. When the fiber bundle is fed into the yarn guide channel, the vortex will drive the fiber ends to rotate, realizing fiber cohesion and twisting.

[0003] However, the existing equipment has the following shortcomings: When the existing jet vortex spinning twister is working, the high-pressure airflow forms a high-speed vortex field through the spiral air channel, which blows away the fiber bundle sent into the yarn guide channel and drives it to rotate and twist. However, the strong diffusion force of the vortex air will cause some fine fibers (such as short fibers and lint) in the fiber bundle to detach from the main body. These fine materials fall into the equipment through the gap between the twister and the yarn guide channel and the air channel gap of the vortex nozzle. Due to the complex internal structure of the equipment, which includes precision components such as air channels and drive components, the fallen fine materials will scatter around in the cavity and eventually accumulate in the gaps between components, the corners of the air channels and the transmission connections. Cleaning requires disassembling the equipment shell and some core components, which is cumbersome and easily damages the precision structure. It is impossible to quickly and thoroughly remove the scattered accumulated materials.

[0004] Therefore, we propose an air-jet vortex spinning twister for viscose-nylon blended core-spun yarn to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment struggles to collect scattered materials, resulting in the materials dispersing inside the equipment and being difficult to clean quickly. This invention proposes a viscose-nylon blended core-spun yarn air-jet vortex spinning twister.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vortex spinning twister for viscose-nylon blended core-spun yarn, comprising a main body, a mounting cover, an air inlet pipe, a feed end, an air outlet pipe, and a collecting device. The mounting cover is installed on the upper end of the main body, the air inlet pipe is fixedly connected to the side of the mounting cover, the feed end is installed on the surface of the main body, the air outlet pipe is installed on the lower side of the main body, and the collecting device is installed on the lower end of the main body. The collecting device includes a connecting ring and a collecting box. The inside of the collecting box is provided with multiple protrusions to easily entangle and collect fine materials. The connecting ring is fixedly connected to the side of the collecting box, the collecting box is installed on the lower end of the main body, a positioning rod is fixedly connected to the lower end of the main body, the connecting ring is sleeved and connected to the surface of the positioning rod, a rubber pad is fixedly connected to the upper end of the connecting ring, a first connecting block is fixedly connected to the lower end of the main body, and a second connecting block is fixedly connected to the lower surface of the connecting ring.

[0007] Furthermore, the surface of the first connecting block is provided with positioning holes, and the surface of the second connecting block is provided with pull holes. By setting positioning holes, the locking block can be limited, reducing the difficulty of positioning the locking block during use.

[0008] Furthermore, a locking block is slidably connected inside the pull hole, with one end of the locking block inserted into the positioning hole. The locking block is provided to facilitate limiting the position of the connecting ring.

[0009] Furthermore, a first spring is fixedly connected to the end of the locking block away from the positioning hole, and the end of the first spring away from the locking block is fixedly connected to the inside of the pull hole. A rubber ring is fixedly connected to the lower surface of the collection box. The rubber ring is provided to facilitate the limiting of the collection box.

[0010] Furthermore, an auxiliary component is fixedly installed inside the air outlet pipe. The auxiliary component includes a filter cover and a moving ring. The moving ring is fixedly connected to the surface of the filter cover. An installation groove is opened on the surface of the air outlet pipe. The filter cover is installed inside the air outlet pipe. A limit hole is opened on the surface of the moving ring. By setting the filter cover, the material can be limited, reducing the possibility of material being easily discharged through the air outlet pipe during equipment use.

[0011] Furthermore, an elastic plate is fixedly connected to the surface of the air outlet pipe. The elastic plate is inserted into the limiting hole to facilitate the limiting of the moving ring.

[0012] Furthermore, a limiting block is fixedly connected to the surface of the elastic plate, and the limiting block is attached to the surface of the moving ring.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a collection device, scattered materials inside the equipment are effectively collected, achieving the function of quickly collecting and cleaning materials. This reduces the problem of existing equipment where the vortex air inside the equipment blows and scatters the materials that enter the equipment, causing them to rotate and stick together. During the blowing, smaller materials are easily dropped into the equipment and move around, making it difficult to quickly clean up the scattered materials. This collection device enables the rapid collection of scattered materials, making it convenient for users to clean up quickly and improving the practicality of the equipment.

[0014] In this invention, by setting an auxiliary component, the filter cover is effectively limited, which prevents material from overflowing. This reduces the situation where, during the use of existing equipment, scattered materials can easily be discharged through the air outlet and enter the discharge equipment, causing blockages and making it difficult for the discharge equipment to operate normally. This auxiliary component achieves material limitation and improves the service life of the equipment. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a vortex spinning twister for viscose-nylon blended core-spun yarn, including a main body 1, a mounting cover 2, an air inlet pipe 3, a feed end 4, an air outlet pipe 5, and a collection device 6. The mounting cover 2 is installed on the upper end of the main body 1, the air inlet pipe 3 is fixedly connected to the side of the mounting cover 2, the feed end 4 is installed on the surface of the main body 1, and the air outlet pipe 5 is installed on the lower side of the main body 1.

[0020] The main body 1 is integrally milled from aerospace-grade aluminum alloy, with an anodized inner wall and a surface roughness Ra≤0.2μm. This reduces frictional damage between the fibers and the inner wall, prevents viscose fibers from sticking together due to moisture absorption, and ensures smooth twisting. The main body 1 is the core twisting cavity. The mounting cover 2 is bolted to the upper end of the main body 1. A spiral air guide groove is provided inside the cover, which converts the high-pressure airflow from the air inlet pipe 3 into a stable vortex, providing continuous power for fiber twisting. The sealing structure prevents insufficient twisting force due to airflow leakage. The tube 3 is made of stainless steel and has an airflow regulator at the end to stabilize the input air pressure at 0.6-0.8MPa, avoiding uneven twisting caused by air pressure fluctuations. It is suitable for the twisting requirements of viscose-nylon blended fibers. The feed end 4 has a conical guide structure with a polished inner wall and fiber bundling teeth, which can initially separate the viscose and nylon fibers and guide them into the twisting chamber in an orderly manner, preventing the fibers from tangling and clogging. The exhaust pipe 5 is seamlessly welded to the main body 1 and has a guide plate inside to guide the vortex gas to be discharged smoothly, avoiding the turbulent airflow that could cause loose fibers to be drawn into the exhaust channel.

[0021] The following section will describe the specific setup and function of its collection device 6 and auxiliary components 7.

[0022] In this implementation scheme: The collecting device 6 is installed at the lower end of the main body 1 and is the key mechanism for the centralized collection of loose fibers during the twisting process. It overcomes the defect of existing equipment where loose fibers scatter inside the equipment. Through the detachable collecting box 62 and the elastic locking structure, it achieves rapid cleaning of loose fibers and convenient replacement of the collecting box 62. The collecting device 6 includes a connecting ring 61 and a collecting box 62. The inside of the collecting box 62 is provided with multiple protrusions. The protrusions are barbed elastic structures made of silicone material, which can efficiently wrap and hook fine loose fibers without damaging the fibers and preventing secondary scattering of loose fibers. At the same time, the gaps between the protrusions facilitate the complete peeling of loose fibers during subsequent cleaning, making it easy to remove fine fibers. Small materials are collected by winding. The connecting ring 61 is fixedly connected to the side of the collection box 62. The collection box 62 is installed at the lower end of the main body 1. The lower end of the main body 1 is fixedly connected to the positioning rod 64. The connecting ring 61 is sleeved and connected to the surface of the positioning rod 64. The upper end of the connecting ring 61 is fixedly connected to the rubber pad 63. The rubber pad 63 is made of high-temperature resistant silicone rubber and can be compressed up to 2mm. It can fill the gap between the connecting ring 61 and the main body 1 to achieve sealing and dust prevention. At the same time, it can buffer the vibration of the equipment during operation and avoid abnormal noise from the collection box 62. The lower end of the main body 1 is fixedly connected to the first connecting block 65, and the lower surface of the connecting ring 61 is fixedly connected to the second connecting block 66.

[0023] Specifically, the surface of the first connecting block 65 is provided with a positioning hole 610, and the surface of the second connecting block 66 is provided with a pull hole 67.

[0024] In this embodiment, by setting the positioning hole 610, the card block 68 can be limited, reducing the difficulty of positioning the card block 68 when the device is in use.

[0025] Specifically, a locking block 68 is slidably connected inside the pull hole 67. One end of the locking block 68 is inserted into the positioning hole 610. The locking block 68 is set to limit the movement of the connecting ring 61.

[0026] Specifically, a first spring 69 is fixedly connected to the end of the locking block 68 away from the positioning hole 610. The first spring 69 is a compression spring with an elastic coefficient that has been precisely calculated. It can provide sufficient locking force to ensure the stability of the collection box 62 without making the locking block 68 too difficult to disassemble, making it suitable for frequent operation by workshop workers. The end of the first spring 69 away from the locking block 68 is fixedly connected to the inside of the pull hole 67. A rubber ring 611 is fixedly connected to the lower surface of the collection box 62. The rubber ring 611 is set to facilitate the limiting of the collection box 62.

[0027] In this implementation scheme: An auxiliary component 7 is fixedly installed inside the exhaust pipe 5. This is the core structure to prevent loose fibers from overflowing with the exhaust. The filter cover 71 with elastic locking achieves precise filtration of the exhaust channel, blocking loose fibers without affecting the airflow. This solves the problem of subsequent pipe blockage caused by loose fibers in the exhaust of existing equipment. The auxiliary component 7 includes a filter cover 71 and a moving ring 72. The moving ring 72 is fixedly connected to the surface of the filter cover 71. The filter cover 71 is made of polypropylene, which is corrosion-resistant and lightweight, and easy to install and disassemble. The outer diameter of the moving ring 72 is precisely matched with the mounting groove 73 to ensure that the filter cover 71 is centered and without deviation after installation. The surface of the exhaust pipe 5 has a mounting groove 73, and the filter cover 71 is installed inside the exhaust pipe 5. The surface of the moving ring 72 has a limiting hole 76.

[0028] In this embodiment, by setting the filter cover 71, the material can be limited, reducing the possibility that the material will easily be discharged through the air outlet pipe 5 when the equipment is in use.

[0029] Specifically, an elastic plate 74 is fixedly connected to the surface of the air outlet pipe 5. The elastic plate 74 is made of spring steel and has good elastic deformation capability. It can achieve a tight engagement with the limiting hole 76 through its own elasticity, without the need for additional locking components, thus simplifying the structure. The elastic plate 74 is inserted into the inside of the limiting hole 76. The elastic plate 74 is set to facilitate the limiting of the moving ring 72.

[0030] Specifically, a limiting block 75 is fixedly connected to the surface of the elastic plate 74. The limiting block 75 has an arc-shaped structure and fits against the outer circular surface of the moving ring 72, which can further restrict the axial movement of the moving ring 72 and prevent the elastic plate 74 from loosening due to airflow impact. The limiting block 75 is fitted and connected to the surface of the moving ring 72.

[0031] Working principle: During operation, the user installs the equipment in the air-jet vortex spinning machine. After the core yarn is connected to the equipment through the guide inside the main body 1, the material enters the equipment through the feed end 4. Air is then injected through the air inlet pipe 3, and the gas enters the equipment through the threaded channel inside the mounting cover 2 to rotate and bond the yarn. The gas is discharged through the air outlet pipe 5. After prolonged use, when it is necessary to clean the loose material inside the equipment, the user moves the locking block 68, which compresses the first spring 69 to generate elasticity. The locking block 68 then moves and disengages from the positioning hole 610 inside the first connecting block 65, and the connecting ring 61 loses its elasticity. The binding and pulling of the connecting ring 61 through the surface of the positioning rod 64 allows the collection box 62 to be detached from the lower end of the main body 1 for replacement. By setting up the collection device 6, the scattered materials inside the equipment are effectively collected, which plays a role in quickly collecting and cleaning materials. This reduces the problem that when the existing equipment is in use, the vortex air inside the equipment blows the materials that enter the equipment and makes them rotate and stick together. When the materials are blown apart, the smaller materials are easy to fall into the equipment and move around. When cleaning, it is difficult to quickly clean up the scattered materials. This collection device 6 realizes the rapid collection of scattered materials, which makes it convenient for users to clean up quickly and improves the practicality of the equipment.

[0032] By setting auxiliary component 7, when the equipment is discharging air, the user installs the filter cover 71 inside the air outlet pipe 5. When the moving ring 72 moves inside the mounting groove 73, it abuts the limiting block 75, which moves the elastic plate 74. When the moving ring 72 is fully engaged with the mounting groove 73, the limiting block 75 and the surface of the moving ring 72 are mechanically locked. By setting auxiliary component 7, the filter cover 71 is effectively limited, which prevents material from overflowing. This reduces the situation where scattered materials can easily be discharged through the air outlet pipe 5 and enter the discharge equipment, causing blockages and making it difficult for the discharge equipment to operate normally. This auxiliary component 7 achieves material limitation and improves the service life of the equipment.

[0033] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
