Description

Technical Field

[0001] This utility model relates to the field of fiber retwisting machines, specifically to a fiber retwisting machine with a lifting and lowering yarn guide frame. Background Technology

[0002] A fiber retwisting machine is a piece of equipment specifically used in the textile industry. Its main function is to combine multiple strands of fiber or yarn through a multi-step twisting process to enhance their performance. This equipment retwistwists the basalt fibers after initial twisting in the opposite or same direction to form a denser and more uniform spiral structure, thereby improving the strength, abrasion resistance, luster and elasticity of the fibers.

[0003] Fiber retwirling machines are widely used in the production of high-strength industrial threads, such as basalt fiber sewing thread, fishing net thread, and reinforced composite materials. Basalt fiber has excellent high temperature resistance, corrosion resistance, and high strength properties. The use of fiber retwirling machines further enhances these properties, making it widely used in high-requirement fields such as aerospace, automobile manufacturing, and building reinforcement.

[0004] In the existing technology, the yarn guide frame of the fiber retwisting machine is usually a fixed structure, which has the defects of being unable to be raised or lowered and difficult to disassemble. This makes it impossible to adjust the height according to process requirements, affecting the control of yarn tension and twist. At the same time, due to the fixed structure of the design, the disassembly process of the yarn guide frame becomes difficult, increasing the difficulty of equipment maintenance and cleaning, and thus affecting production efficiency and yarn quality.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The anti-slip groove is a strip structure composed of several diamond-shaped grooves connected end to end, and the strip structure is evenly surrounded on the outer side of the yarn guide roller.

[0010] Furthermore, to enable automated lifting and lowering adjustment of the yarn guide frame, the adjustment assembly includes a motor mounted on the top of the retwisting machine body.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, a fiber retwisting machine with a yarn guide frame lifting mechanism is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the fiber retwisting machine with yarn guide frame lifting according to the embodiment of the present utility model includes a retwisting machine body 1, a control panel 2 is provided at the bottom of one side of the retwisting machine body 1, an adjustment component 3 is provided at the top of one side of the retwisting machine body 1, a yarn guide frame 4 is provided at the top of the adjustment component 3, a plurality of yarn guide rollers 5 are provided inside the yarn guide frame 4, and a connecting component 6 that cooperates with the yarn guide frame 4 is provided at both ends of the yarn guide rollers 5.

[0026] By utilizing the aforementioned technical solutions, this utility model, through the combined action of the main body 1 of the retwisting machine, the adjusting component 3, and the yarn guide frame 4, significantly improves the physical properties and quality of the yarn. It can tightly combine multiple fibers or yarns, enhancing the yarn's strength, abrasion resistance, elasticity, and luster, and improving its uniformity and stability. Simultaneously, in conjunction with the automated adjusting and lifting yarn guide frame 4, the height can be adjusted according to different yarn types and process requirements, thereby precisely controlling the yarn tension and twist to ensure product quality stability. The combined action of the adjusting component 3, the yarn guide frame 4, the yarn guide roller 5, and the connecting component 6 significantly improves the flexibility of fiber processing and the equipment's maintenance efficiency. The lifting function allows the yarn guide frame to adjust its height according to different yarn types and process requirements, thereby precisely controlling the yarn tension and twist to ensure product quality stability. Furthermore, the easy-to-disassemble design simplifies the cleaning, maintenance, and repair process, reduces downtime, and improves production efficiency. This not only extends the equipment's service life but also reduces maintenance costs, providing strong support for the continuity and efficiency of textile production.

[0027] In one embodiment, for the aforementioned yarn guide roller 5, anti-slip grooves 7 are uniformly provided on the outer side of the yarn guide roller 5, and spiral limiting blocks 8 are provided on the outer side of each anti-slip groove 7. The thread directions of the spiral limiting blocks 8 on the outer side of any two adjacent sets of yarn guide rollers 5 in the vertical direction are opposite. The anti-slip grooves 7 are strip-shaped structures composed of several diamond-shaped grooves connected end to end, and the several strip-shaped structures are uniformly surrounding the outer side of the yarn guide roller 5. This improves the stability and effectiveness of the yarn guide roller 5 during operation.

[0028] It should be explained that the guide roller 5 enhances the frictional resistance between the basalt fiber retwisted yarn and the surface of the guide roller 5 through the uniformly distributed anti-slip grooves 7 on its outer side, effectively preventing the yarn from slipping or deviating during high-speed operation and ensuring stable tension. At the same time, the spiral limiting blocks 8 on the outer sides of adjacent guide rollers 5 in the vertical direction adopt an opposite thread direction design, forming a complementary limiting effect when the yarn moves up and down, offsetting the yarn tilting or accumulation that may be caused by unilateral thread guidance, thereby achieving dynamic balance in the vertical direction, further improving the uniformity of yarn arrangement and the overall stability of the yarn guiding process. During the retwisting process, the yarn usually needs to be twisted multiple times, and the opposite thread design of adjacent guide rollers can balance the twisting stress of the yarn in the vertical direction, avoiding uneven yarn structure or internal stress concentration caused by torsional force in a single direction, thereby improving the overall stability of the retwisted yarn.

[0029] In addition, the main body 1 of the retwisting machine is a fiber retwisting machine. Its core components include a yarn feeding mechanism, a yarn guide frame 4, a twisting mechanism, and a winding mechanism. The yarn feeding mechanism is responsible for releasing multiple strands of yarn to ensure uniform tension. The yarn guide frame 4 adjusts the yarn path by raising and lowering through the adjustment component 3 to optimize tension and twist control. The twisting mechanism twists the yarn with the help of a spindle or rotor and a yarn guide roller 5 to form a spiral structure, which enhances the strength and elasticity of the yarn. The winding mechanism evenly winds the twisted yarn onto the bobbin for subsequent use. This is existing technology and will not be explained in detail here.

[0030] In one embodiment, the adjustment component 3 includes a motor 301 mounted on the top of the retwisting machine body 1. One end of the output shaft of the motor 301 is mounted on a lead screw 302 that cooperates with the retwisting machine body 1. A slider 303 is mounted on the outer side of the lead screw 302. A movable rod 304 that cooperates with the yarn guide frame 4 is mounted on the top of the slider 303. A movable frame 305 that cooperates with the retwisting machine body 1 is mounted on the outer side of the movable rod 304. A slider 306 that cooperates with the yarn guide frame 4 is mounted on the top of the movable frame 305. A limiting groove 307 that cooperates with the slider 303 is provided on the top of the retwisting machine body 1. A limiting rod 308 is provided through the yarn guide frame 4 on one side of the retwisting machine body 1. A limiting groove 309 that cooperates with the slider 306 is provided on the bottom of the yarn guide frame 4. Both the limiting groove 307 and the limiting groove 309 are concave in shape. Thus, the yarn guide frame 4 can be automatically adjusted in height.

[0031] The working principle of adjustment component 3 is as follows:

[0032] Controlling the motor 301 in the adjustment assembly 3 via the control panel 2 causes the output shaft of the motor 301 to rotate, which in turn causes the lead screw 302 to rotate. This rotation causes the slider 303 to move horizontally along the limiting groove 307. The movement of the slider 303 causes the movable rod 304 to rotate. Simultaneously, with the cooperation of the slider 306 and the limiting groove 309, the movable frame 305 rotates along the top of the retwisting machine body 1. The simultaneous rotation of the movable rod 304 and the movable frame 305 causes the yarn guide 4 to be vertically adjusted along the limiting rod 308.

[0033] In one embodiment, the connecting assembly 6 includes a limiting plate 601 on one side of the yarn guide frame 4, a gripping rod 602 on one side of the limiting plate 601, a support rod 603 on the other side of the limiting plate 601, a support seat 604 cooperating with the yarn guide roller 5 on one side of the support rod 603, and a spring 605 cooperating with the yarn guide frame 4 on the side of the support seat 604 away from the yarn guide roller 5; the outer side of the gripping rod 602 is provided with anti-slip texture 606; thereby facilitating the disassembly and assembly of the yarn guide roller 5.

[0034] The working principle of connection component 6 is as follows:

[0035] When it is necessary to disassemble the yarn guide roller 5, first grasp the handle 602 in the connecting assembly 6 and pull it away from the yarn guide roller 5. Under the pulling action of the handle 602, the support seat 604 will be disengaged from the yarn guide roller 5. At this time, the yarn guide roller 5 can be disassembled from the yarn guide frame 4.

[0036] When it is necessary to install the yarn guide roller 5, first grasp the lever 602 in the connecting assembly 6 and pull it away from the yarn guide roller 5. Under the pulling action of the lever 602, the two sets of support seats 604 on the same horizontal plane move away from each other and compress the spring 605. At this time, align the yarn guide roller 5 with the two sets of support seats 604. Then release the lever 602. Under the reset action of the spring 605, the two sets of support seats 604 contact the yarn guide roller 5, and the installation of the yarn guide roller 5 is completed.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical application, firstly, the motor 301 in the adjustment component 3 is controlled and started through the control panel 2. Under the rotation of the output shaft of the motor 301, the lead screw 302 is driven to rotate. Under the rotation of the lead screw 302, the slider 303 moves horizontally along the limiting groove 307. Under the movement of the slider 303, the movable rod 304 is driven to rotate. Under the rotation of the movable rod 304, and with the cooperation of the slider 306 and the limiting groove 309, the movable frame 305 is driven to rotate along the top of the retwisting machine body 1. Under the simultaneous rotation of the movable rod 304 and the movable frame 305, the yarn guide frame 4 is driven to be adjusted vertically along the limiting rod 308. Then, the retwisting machine body 1 is controlled and started through the control panel 2 to combine multiple fibers or yarns for retwisting through multiple steps. The yarn guide roller 5 is disassembled and assembled through the gripping rod 602 in the connecting component 6.

[0039] The working principle of the main body 1, adjusting component 3, yarn guide roller 5 and connecting component 6 of the retwisting machine is as described above.

[0040] In summary, by utilizing the above-mentioned technical solution of this utility model, the physical properties and quality of yarn are significantly improved through the combined action of the main body 1 of the retwisting machine, the adjusting component 3, and the yarn guide frame 4. It can tightly combine multiple fibers or yarns, enhancing the yarn's strength, abrasion resistance, elasticity, and luster, and improving the yarn's uniformity and stability. Simultaneously, with the cooperation of the automatically adjusting and lifting yarn guide frame 4, the height can be adjusted according to different yarn types and process requirements, thereby precisely controlling the yarn's tension and twist, ensuring product quality stability. Through the combined action of the adjusting component 3, the yarn guide frame 4, the yarn guide roller 5, and the connecting component 6, the flexibility of fiber processing and the maintenance efficiency of the equipment are significantly improved. The lifting function allows the yarn guide frame to adjust its height according to different yarn types and process requirements, thereby precisely controlling the yarn's tension and twist, ensuring product quality stability. Furthermore, the easy-to-disassemble design simplifies the cleaning, maintenance, and repair process of the equipment, reduces downtime, and improves production efficiency.
