Description

Technical Field

[0001] The present invention relates to the technical field of vortex spinning machines, and particularly to an air intake adjustable vortex tube for a vortex spinning machine. Background Art

[0002] As a key equipment in the modern textile industry, the vortex spinning machine occupies an important position in the field of yarn production with its significant advantages such as high efficiency, high output, and low energy consumption. During the vortex spinning process, the air flow environment plays a decisive role in the quality and production efficiency of the yarn. As the core component for controlling the air flow, the performance of the air intake structure directly affects the stability of the entire spinning process and the product quality. The air intake structure of early vortex spinning machines was relatively simple, usually in a fixed air intake mode, making it difficult to flexibly adjust the air intake volume and air flow distribution according to different yarn varieties and spinning process requirements. This results in the inability to create the most suitable spinning air flow environment during actual production. For example, when spinning yarns of different fiber materials and thickness specifications, the unified air intake mode is likely to cause quality problems such as uneven yarn twisting, insufficient strength, and excessive hairiness, seriously affecting the market competitiveness of the product. At the same time, there are also many inconveniences in the maintenance and repair of the traditional air intake structure. Its component connections are complex, lacking a design for quick disassembly and installation. Once internal components fail, maintenance personnel need to spend a lot of time and effort on disassembly, repair, and reassembly, resulting in a long equipment downtime, greatly affecting the production efficiency, and increasing the operating costs of the enterprise. To effectively solve the above problems and meet the growing demand for high-quality and high-efficiency spinning, the research and development of an air intake adjustable vortex tube for a vortex spinning machine provides an innovative solution to address the drawbacks of the traditional air intake structure and promote the upgrade of vortex spinning technology.

[0034] Instructions for use The yarn first enters the conduit 5 from the outside. The conduit 5 is connected to the through hole at the front end of the limit box 4, providing a channel for the yarn to enter the limit box 4. A clamping assembly is arranged inside the limit box 4. When the yarn enters the limit box 4, the micro-motor 6 starts, and the screw rod 24 at its output end rotates. Since the threaded hole on a driving block 20 cooperates with the screw rod 24, the driving block 20 slides in the chute at the front end of the fixed block 19. The sliders 21 at the rear ends of the four driving blocks 20 ensure its stable sliding. As the driving block 20 slides, the inclined surface rack one 22 at its front end meshes with the inclined surface rack two 27 at the rear end of the slide plate 26, driving the slide plate 26 to slide in the cavity guide groove around the inner circumference at the front end of the limit box 4. The guide rod one 28 connected to the front end of the slide plate 26 pushes the arc plate 29 to move. Through the relative movement of the four arc plates 29, the clamping and guiding of yarns of different sizes are realized, ensuring that the yarn can accurately and stably enter the subsequent process.

After the yarn enters the spinning connection pipe body 1 through the yarn guide needle 14, it will enter the inside of the spindle 9 and perform preliminary spinning operations under the action of the spindle 9. Motors 10 are installed on both sides at the upper end of the spinning connection pipe body 1. The motors 10 drive the telescopic rods 11 to move up and down. The connecting plate 12 connected to the upper end of the telescopic rod 11 drives the yarn guide needle 14 to move up and down. The lower end of the yarn guide needle 14 enters the upper end inside the spinning connection pipe body 1 through the sealing rubber ring 15. The auxiliary spring 13 is sleeved on the upper end of the yarn guide needle 14 and is connected to the lower end of the connecting plate 12 and the upper end of the sealing rubber ring 15 respectively. By controlling the telescopic length of the telescopic rod 11, the motor 10 can adjust the position of the yarn guide needle 14 inside the spinning connection pipe body 1. At the same time, the auxiliary spring 13 can play a role in buffering and fine-tuning the position of the yarn guide needle 14, ensuring the stability of yarn guiding. A number of air extraction holes are arranged in a row around the lower end surface of the spinning connection pipe body 1. The function of these air extraction holes is to extract the air inside the pipe during the spinning process. By extracting the air, a specific airflow environment can be formed inside the pipe, which is helpful for operations such as yarn twisting and shaping. At the same time, some impurities generated during the spinning process can also be discharged from the pipe through air extraction, ensuring the cleanliness of the spinning environment. Quick-release structures are arranged on both sides inside the two connection seats 2. The through grooves on the opposite surfaces of the inner sides of the connection seats 2 correspond to the positioning grooves opened on the base 7. The front end of the guide rod two 31 sleeved in the through groove is inserted into the positioning groove to position the base 7. The rear end of the guide rod two 31 extends into the clamping box 30, and a compression spring 33 is connected to its surface, with the other end connected to the inner wall of the clamping box 30. Inside the clamping box 30, a fixing plate 32 is installed at the upper end of the guide rod two 31. The inclined groove on the surface of the fixing plate 32 is sleeved on the outer end of the fixing pin 36. The fixing pin 36 is installed in the center of the pressing plate 35. The front end of the pressing plate 35 extends to the outside of the connection seat 2 through the pressing opening and the opening of the connection seat 2. When maintenance, repair or component replacement is required, press the pressing plate 35,The pressing plate 35 drives the fixing pin 36 to slide in the inclined slot of the fixing plate 32, causing the fixing plate 32 to move upward. The compression spring 33 is compressed, and the rear end of the second guide rod 31 is withdrawn from the positioning slot of the base 7, so that related components such as the base 7 can be quickly disassembled, facilitating maintenance and repair work. During installation, release the pressing plate 35, and the compression spring 33 rebounds, pushing the front end of the second guide rod 31 to insert into the positioning slot again to complete the quick installation of the components.
