Description

Technical Field

[0001] The invention relates to the technical field of textile yarn preparation, in particular to a method and equipment for preparing tension-resistant textile yarn. Background Art

[0002] Because tensile-resistant yarns are made of high-performance fiber materials and advanced textile technology, they are stronger than traditional yarns and can withstand greater tension. When preparing aviation parachutes or wing suits for flying, high-strength tensile-resistant yarns are needed to ensure the firmness and strength of the aviation parachutes or wing suits when used for flying.

[0003] For example, the "A production process and preparation device for embroidery textile yarn" with publication number: CN116121985A, includes the following steps: using a fancy twisting machine to make the core thread and the decorative thread as the weft thread, and the binding thread as the warp thread, weaving the weft thread and the warp thread into cloth, cutting off the weft thread of the cloth, leaving spare yarn, scouring and dyeing the yarn, fixing the color yarn, and softening the yarn. When the soft yarn processing in S5 is completed, the yarn is taken out from the scouring device, and then placed on the drying equipment to dry the dye on the yarn. When the dye on the yarn is mostly dried, the yarn is placed on the yarn drying device for yarn drying. When the yarn drying in S6 is completed, the yarn winding can be performed.

[0004] However, in the prior art, in the process of preparing textile yarn, it is necessary to wind and take up the yarn multiple times in order to carry out subsequent processing and quality inspection of the yarn. In this process, the appearance, uniformity and impurities of the yarn can also be observed. However, during the multiple winding processes, if the yarn encounters bending or friction, and lacks effective guiding function, it is easy to cause the yarn to become knotted. During the winding process, insufficient tension will also cause drift during the winding process, and then the finished product will wrinkle after winding. Summary of the invention

The coordinated work of the driving motor, the active rod, the rotating rod and the winding rod realizes the continuous and stable winding of the yarn. At the same time, the setting of the active wheel, the driven wheel and the synchronous belt improves the synchronization of winding and guiding, and further improves the winding efficiency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0038] Reference Figure 1-6 As shown: a preparation device for tension-resistant textile yarn, comprising a bottom plate 1 and a tensioning assembly 3 installed on one side of its top, the tensioning assembly 3 is used to tension the yarn, a guide mechanism 4 is installed in the center of the top of the bottom plate 1, and a winding mechanism 5 is installed on one side of the top of the bottom plate 1;

[0039] The winding mechanism 5 includes a rotating rod 51, both ends of the rotating rod 51 are fixedly connected to a fixed block 52, the outer surface of the fixed block 52 is symmetrically fixedly connected to a first fixed plate 521, the surface of the fixed block 52 is rotatably connected to a rotating sleeve 53, the outer surface of the rotating sleeve 53 is symmetrically fixedly connected to two second fixed plates 531, one end of one of the rotating sleeves 53 is rotatably connected to a fixed sleeve 58, the fixed sleeve 58 is fixedly connected to the outer wall of the rotating rod 51, the outer surface of the fixed sleeve 58 is rotatably connected to a driving block 55, one end of the driving block 55 starts with a limiting hole 551, the limiting hole A connecting rod 54 is slidably connected to the inner cavity 551, and one end of the connecting rod 54 is rotatably connected to two linkage rods 56. The opposite ends of the two linkage rods 56 are rotatably connected to rotating frames 561, one of the rotating frames 561 is fixedly connected to the second fixed plate 531, and the other rotating frame 561 is fixedly connected to the first fixed plate 521. A handle 552 is fixedly connected to the top of one end of the driving block 55, a first winding rod 57 is fixedly connected between the two second fixed plates 531, and a second winding rod 59 is fixedly connected between the two first fixed plates 521.

[0040] In this embodiment, during the delicate process of preparing the textile yarn, the rotation of the rotating rod 51 and the coordinated cooperation of the two first winding rods 57 and the two second winding rods 59 ensure that the yarn can be wound evenly and tightly.

[0041] When the winding work is completed, the driving block 55 is driven to rotate by the handle 552. In this process, the driving block 55 will rotate accurately with the fixing sleeve 58 as the center. As the driving block 55 rotates, it will apply an appropriate force to the connecting rod 54 inside the limiting hole 551. This force not only drives the movement of the connecting rod 54, but also ensures that the connecting rod 54 can slide smoothly inside the limiting hole 551.

[0042] The movement of the connecting rod 54 further triggers the coordinated movement of the two linkage rods 56. Driven by the connecting rod 54, the two linkage rods 56 will change the angle between them. With the movement of the linkage rod 56, the rotating frame 561 starts to work. It will apply a precise force to the second fixed plate 531, so that the rotating sleeve 53 can rotate smoothly on the surface of the fixed block 52. This step not only changes the position of the second fixed plate 531, but also ensures that the angle between it and the first fixed plate 521 can change.

[0043] Before winding the yarn, the second fixing plate 531 and the first fixing plate 521 are arranged vertically. This arrangement makes full use of the maximum perimeter of the square, ensuring that the yarn can maintain maximum stability and compactness during the winding process. However, after winding, in order to facilitate the removal of the yarn, the angle between the two fixing plates needs to be changed.

[0044] Through the coordinated action of the movable linkage rod 56 and the rotating frame 561, we successfully changed the position of the second fixed plate 531 and the angle between the second fixed plate 531 and the first fixed plate 521. This not only ensures the quality and stability of the yarn winding, but also enables the yarn to be quickly taken out and ensures that no knots will occur during the winding process. Embodiment 2

[0045] Figure 7 and Figure 8 As shown, the guide mechanism 4 includes a support plate 43, both sides of which are fixedly connected to a fixing seat 44, a driving rod 41 is installed above the support plate 43, both ends of the driving rod 41 are rotatably connected to the fixing seat 44, a spiral groove 42 begins to be formed on the surface of the driving rod 41, and a sliding sleeve 45 is slidably connected to the surface of the driving rod 41. A push block 48 is rotatably connected to the inner wall of the sliding sleeve 45, and the push block 48 is slidably connected to the spiral groove 42. Two limit rods 46 are symmetrically fixedly connected to the top of the sliding sleeve 45. A guide groove 431 begins to be formed at the top of the support plate 43, and a sliding block 471 is slidably connected inside the guide groove 431. A fixed rod 47 is fixedly connected to the top of the sliding block 471, and the top of the fixed rod 47 is fixedly connected to the bottom of the sliding sleeve 45.

[0046] In this embodiment, during the process of winding the yarn, when the driving rod 41 starts to rotate, the spiral groove 42 on its surface will apply a continuous and stable force to the push block 48. This force is transmitted to the sliding sleeve 45 through the push block 48, so that the sliding sleeve 45 starts to slide on the surface of the spiral groove 42. This sliding action of the sliding sleeve 45 further drives the two limiting rods 46 on both sides thereof, so that the yarn between the limiting rods 46 can move smoothly.

[0047] In this way, during the yarn winding process, the system can automatically adjust the position of the yarn to ensure that the yarn remains smooth during the winding process and avoid problems such as knotting and entanglement. This not only improves the winding efficiency, but also greatly reduces the risk of yarn damage.

[0048] Meanwhile, during the movement of the sliding sleeve 45, the fixed rod 47 at the bottom thereof drives the sliding block 471 to move together. The sliding block 471 moves precisely in a straight line under the restriction of the guide groove 431. This guide design not only improves the stability of the movement of the sliding sleeve 45, but also ensures the stability of the yarn during the movement.

[0049] When the sliding sleeve 45 moves to the end of the driving rod 41, the double direction design of the spiral groove 42 plays a key role. It continues to exert force on the push block 48, so that the push block 48 drives the sliding sleeve 45 to start reverse movement. This reverse movement allows the yarn to continue to remain smooth during the winding process and avoid any possible obstacles. Embodiment 3

[0050] according to Figure 2 , Figure 3 , Figure 7 and Fig. 9 As shown, the tensioning assembly 3 includes two mounting blocks 31, and three plug-in slots 35 are provided at the top of the mounting blocks 31. A second lifting rod 37 is slidably connected inside one of the plug-in slots 35, and a first lifting rod 32 is slidably connected inside the other two plug-in slots 35. A second tensioning roller 36 is rotatably connected between the two second lifting rods 37, and a first tensioning roller 33 is rotatably connected between the two first lifting rods 32. Three locking rods 34 are rotatably connected to one side of one of the mounting blocks 31, and one end of the locking rod 34 passes through the mounting block 31, and the second lifting rod 37 and the first lifting rod 32 are both in contact with one end of the locking rod 34. A support block 25 is fixedly connected to one side of the top of the bottom plate 1, and a driving motor 2 is installed on one side of the support block 25, and an active rod 21 is fixedly connected to the output end of the driving motor 2. A driving wheel 22 is fixedly connected to the outer surface of the active rod 21, and one end of the active rod 21 is fixedly connected to one end of the rotating rod 51. A synchronous belt 24 is sleeved on the surface of the driving wheel 22 , and a driven wheel 23 is sleeved on one end of the synchronous belt 24 . The shaft end of the driven wheel 23 is fixedly connected to one end of the driving rod 41 .

[0051] In this embodiment, during the winding process of the textile yarn, a combination of two first tensioning rollers 33 and one second tensioning roller 36 is used to ensure a moderate tension on the yarn.

[0052] The first lifting rod 32 and the second lifting rod 37 can slide up and down inside the insertion slot 35, and the positions of the two first tensioning rollers 33 and the one second tensioning roller 36 can be adjusted according to actual needs. By twisting the locking rod 34, the lifting rod can be fixed at the desired position, thereby ensuring the stability of the tensioning roller and the adjustability of the tensioning strength.

[0053] During the winding process, the driving motor 2 starts to drive the active rod 21 to start rotating. The rotation of the active rod 21 drives the rotating rod 51 to rotate together, which makes the first fixed plate 521 and the second fixed plate 531 rotate accordingly, and the first winding rod 57 and the second winding rod 59 start to perform the winding operation, and the tensioned yarn is tightly and orderly wound up.

[0054] During the rotation of the rotating rod 51, the driving wheel 22 on the outer surface of the active rod 21 will also rotate synchronously. The driving wheel 22 is connected to the driven wheel 23 through the synchronous belt 24 on the surface, thereby driving the driven wheel 23 to rotate together. Not only does it ensure the continuity and stability of the winding operation, but it also improves the synchronization of winding and guiding. The rotation of the driving rod 41 is also a key link in this process. It works in conjunction with other components to achieve efficient winding of the yarn. Embodiment 4

[0055] A method for preparing a tensile-resistant textile yarn comprises the following steps:

[0056] 1) Material selection: Select polylactic acid fiber and polyacrylate polymer as raw materials, the ratio of the two is controlled to be 2:3, and a wetting agent is added during the mixing process;

[0057] 2) Pretreatment: Pretreatment of the selected synthetic fibers, first removing impurities from the synthetic fibers, and then controlling the fiber line length and diameter to remain consistent;

[0058] 3) Preliminary treatment: opening and combing the mixed fibers, and then winding them up after treatment;

[0059] 4) Secondary processing: Spin the wound fibers, stretch and rotate them into yarn using a spinning machine, and then wind them up;

[0060] 5) Strengthening treatment: The yarn is strengthened by chemical or physical treatment. Before winding, the yarn can be heated and coated first, and finally stretched before winding;

[0061] 6) Finishing and packaging: The yarn after strengthening is finished, and then the quality is checked, loose fibers are trimmed and the density of the yarn is adjusted.

[0062] The use method and working principle of the device: During the winding process, the yarn is tensioned by using two first tensioning rollers 33 and one second tensioning roller 36, which can not only improve the quality of the yarn, but also ensure that the yarn will not be disturbed during the winding process. By adjusting the first lifting rod 32 and the second lifting rod 37 to slide up and down inside the plug-in slot 35, the positions of the two first tensioning rollers 33 and one second tensioning roller 36 can be changed. Subsequently, by twisting the locking rod 34, one end of which abuts against the first lifting rod 32 or the second lifting rod 37, the position of the tensioning roller is fixed to ensure stability during tensioning, and the tensioning strength can be adjusted as needed.

[0063] During the winding process, the driving motor 2 is started to drive the active rod 21 to rotate, and then drives the rotating rod 51 to rotate. Under the coordinated action of the two first winding rods 57 and the two second winding rods 59, the tensioned yarn is wound in an orderly manner. When the winding is completed, the driving block 55 is driven by the operating handle 552 to rotate around the fixed sleeve 58. In this process, the driving block 55 applies a force to the connecting rod 54 inside the limiting hole 551, so that it moves and slides inside the limiting hole 551. The movement of the connecting rod 54 further drives the two linkage rods 56 to change the angle, and at the same time, the rotating frame 561 applies a force to the second fixed plate 531, so that the rotating sleeve 53 rotates on the surface of the fixed block 52. Before winding the yarn, the second fixed plate 531 and the first fixed plate 521 are arranged vertically to make full use of the maximum perimeter of the square to improve the winding efficiency. After winding is completed, the position of the second fixing plate 531 and the angle between the second fixing plate 531 and the first fixing plate 521 can be changed by adjusting the linkage rod 56, so as to facilitate taking the wound yarn.

[0064] In addition, during the rotation of the rotating rod 51, the driving wheel 22 on the outer surface of the active rod 21 rotates synchronously, and drives the driven wheel 23 to rotate through the synchronous belt 24, thereby ensuring the continuity and stability of the winding operation. At the same time, the rotation of the driving rod 41 also improves the synchronization of winding and guiding. When the driving rod 41 rotates, the spiral groove 42 on its surface applies a continuous and stable force to the push block 48, pushing the sliding sleeve 45 to slide on the surface of the spiral groove 42. The sliding of the sliding sleeve 45 drives the yarn between the two limit rods 46 to move, thereby adjusting the position of the yarn and ensuring smoother yarn winding. During the movement of the sliding sleeve 45, the fixed rod 47 at the bottom end drives the sliding block 471 to move linearly under the restriction of the guide groove 431, which not only ensures the smooth movement of the sliding sleeve 45, but also enhances the stability of the yarn movement. When the sliding sleeve 45 moves to the end of the driving rod 41, the double direction design of the spiral groove 42 enables it to continue to exert force on the pushing block 48, pushing the sliding sleeve 45 to move in the opposite direction, thereby ensuring that the yarn remains smooth throughout the entire winding process.
