Description

Technical Field

[0001] The present invention relates to the technical field of textile materials and engineering, and particularly to a production device and method for an inorganic component-modified yarn. Background Art

[0002] Textile materials and engineering technology is a discipline that studies fibers, yarns, fabrics, and their manufacturing processes, covering the processing and application of natural fibers (such as cotton and wool), synthetic fibers (such as polyester and nylon), and high-performance fibers (such as carbon fiber and aramid). The core includes spinning, weaving, printing and dyeing, post-finishing, etc. The goal is to endow materials with special properties (such as waterproof, flame-retardant, conductive) through physical, chemical, or nanotechnology. The modern trend focuses on intelligent production (Industry 4.0), green processes (waterless dyeing), and composite materials (inorganic / organic hybrids), promoting the cross-border application of textiles in medical, military, aerospace, and other fields. In yarn production, a relatively key step is impregnation, which is a process of immersing yarns or fabrics in a dyeing solution / modifying solution containing inorganic components, and allowing the colorant or functional components (such as inorganic particles) to penetrate into the interior of the fibers through adsorption and diffusion.

[0003] However, in the prior art, according to the needs of different customers, the components of the modified inorganic solution required for the yarn are also different. And the beam member on some existing devices is welded. This design cannot quickly disassemble the beam member for cleaning, resulting in the old inorganic solution remaining on it, thus affecting the impregnation degree of the new inorganic solution, and reducing the quality of the modified yarn.

[0004] Therefore, in view of the above problems, a production device and method for an inorganic component-modified yarn are proposed. Summary of the Invention

[0005] In order to make up for the above deficiencies, the present invention provides a production device and method for an inorganic component-modified yarn, aiming to improve the problem in the prior art that the beam member cannot be quickly disassembled for cleaning, resulting in the residue of the old inorganic solution, thus affecting the impregnation degree of the new inorganic solution, and reducing the quality of the modified yarn.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An inorganic component modified yarn production device, including a machine body, a feeding component for carrying a yarn roller is fixedly connected to the front end of the machine body, a support is fixedly connected to the top end of the feeding component, a plurality of threaded rods are threadedly connected to the inner wall of the support, one end of the threaded rod is rotatably connected to a moving box, a pressing plate is rotatably connected to the top end of the moving box, rubber strips for clamping with a bottom box are fixedly connected to both sides of the pressing plate, a hook plate is rotatably connected to both sides of the inner wall of the moving box, a counterweight block is fixedly connected to the bottom end of the hook plate, a fixed rod is fixedly connected to one side of the pressing plate, a support rod is detachably connected to the inner wall of the moving box, two clamping grooves for clamping with the hook plate are formed in the outer part of the support rod, a sequin is fixedly connected to the top end of the support rod, the other end of the support rod is fixedly connected to the bottom box, and a slurry box is fixedly connected to the inside of the feeding component;

[0012] As a further description of the above technical solution:

[0013] A guiding ring is fixedly connected to the top end of the carrying platform, and a sponge box is fixedly connected to the front end of the guiding ring;

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] Inside the machine body, there is an electric heating drying room for drying the modified yarn after impregnation. At the front end of the machine body, there is a lead frame fixedly connected for guiding the dried yarn.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Refer to Figures 1 to 3, an embodiment provided by the present invention: a production device for inorganic component-modified yarn, including a machine body 1. Here, the machine body 1 is the main body of the modified yarn production device. A feeding component for carrying a yarn roller is fixedly connected to the front end of the machine body 1. Here, the feeding component is used to place the yarn roller that needs to be modified with an inorganic solution. The feeding component includes a carrying platform 2. The rear end of the carrying platform 2 is fixedly connected to the front end of the machine body 1. Here, the machine body provides stable support for the carrying platform 2. Two support blocks 3 are fixedly connected to the front end of the carrying platform 2. A feeding roller 4 is arranged inside the two support blocks 3. Here, the support blocks 3 provide stable support for the feeding roller 4. An elastic traction rope 5 is fixedly connected to the top end of the support block 3. The other end of the elastic traction rope 5 is fixedly connected to a clamping block 6 that is clamped with the support block 3. Here, the clamping block 6 can effectively prevent the feeding roller 4 from accidentally detaching from the two support blocks 3, and the elastic traction rope 5 ensures that the clamping block 6 will not be lost when not in use. At the same time, because it itself has elasticity, it will be tightened when the clamping block 6 is engaged with the support block 3 and will not be involved in the feeding roller 4.

[0039] Referring to Figure 1 , Figure 4 and Figure 5 , a support 7 is fixedly connected to the top end of the feeding component. The bottom end of the support 7 is fixedly connected to the top end of the carrying platform 2. Here, the carrying platform 2 provides stable support for the support 7. A plurality of threaded rods 8 are threadedly connected to the inner wall of the support 7. One end of the threaded rod 8 is rotatably connected to a moving box 9. Here, turning the threaded rod 8 can drive the moving box 9 to move left and right. The top end of the moving box 9 is rotatably connected to a pressing plate 10. Here, the moving box 9 provides a stable rotating space for the pressing plate 10. Rubber strips 11 that are clamped with the moving box 9 are fixedly connected to both sides of the pressing plate 10. When in the closed state (as shown in Figure 4 ), the rubber strip 11 will be engaged with the inner wall of the moving box 9. Hook plates 12 are rotatably connected to both sides of the inner wall of the moving box 9. A counterweight block 13 is fixedly connected to the bottom end of the hook plate 12. Here, the counterweight block 13 makes the hook plate 12 hang naturally under normal conditions. This is the non-locking state.

[0040] One side of the pressing plate 10 is fixedly connected with a fixed rod 14. The outer part of the fixed rod 14 is slidably connected to the inner wall of the bracket 7. The existence of the fixed rod 14 here ensures that the moving box 9 will not skew when driven by the threaded rod 8 and keeps linear motion. A support rod 15 is detachably connected to the inner wall of the moving box 9. Two clamping grooves 16 for clamping with the hook plate 12 are formed on the outer part of the support rod 15. At the locked state, the bottom end of the hook plate 12 will hook inside the clamping groove 16 (the clamping groove 16 here does not extend to the leftmost side of the support rod 15 all the time, leaving a little distance to prevent the accidental detachment of the support rod 15). The top end of the support rod 15 is fixedly connected with a bright piece 17. The bright piece 17 here mainly provides a prompt effect. When the bright piece 17 on the support rod 15 can be seen from the notch at the top of the pressing plate 10, it means that the support rod 15 is in a vertical state at this time and its locked state can be completed.

[0041] Refer to Figure 4 , Figure 6 and Figure 7 , the other end of the support rod 15 is fixedly connected with a bottom box 18. When the support rod 15 moves with the moving box 9, it can drive the bottom box 18 at its bottom end to move together. A plurality of sliding rods 19 are slidably connected to the inner wall of the bottom box 18. The bottom box 18 here provides a stable sliding space for the sliding rods 19. The top ends of every two sliding rods 19 are fixedly connected with a top plate 20. The top plate 20 here can ensure that the plurality of sliding rods 19 slide synchronously, effectively preventing the situation of jamming. The other ends of the plurality of sliding rods 19 are rotatably connected with a first pressing belt 21. The bottom end of the inner wall of the bottom box 18 is rotatably connected with a second pressing belt 22. The first pressing belt 21 and the second pressing belt 22 here can clamp the yarn and at the same time squeeze out a small amount of air inside it, improving the permeability of the inorganic solution, thereby improving the quality of the modified yarn. The outer part of the first pressing belt 21 is in contact with the outer part of the second pressing belt 22. Two springs 23 are fixedly connected to the bottom end of the top plate 20. The other ends of the springs 23 are fixedly connected to the top of the bottom box 18. The springs 23 here can ensure that there is a pulling force between the top plate 20 and the bottom box 18, so as to transmit this force to the first pressing belt 21 to complete its cooperation with the second pressing belt 22.

[0042] Refer to Figure 1 and Figure 8, inside the feeding component, there is a pulp box 24 fixedly connected. The inside of the pulp box 24 is used to place the inorganic solution for modifying the yarn. The bottom end of the pulp box 24 is fixedly connected inside the bearing platform 2. The top end of the bearing platform 2 is fixedly connected with a guiding ring 25. The guiding ring 25 here can guide the direction of the yarn after dyeing to ensure that the general position is correct. The front end of the guiding ring 25 is fixedly connected with a sponge box 26. The inside of the sponge box 26 here is used to place the sponge for absorbing the excess inorganic solution on the yarn to prevent waste. At the same time, after excessive absorption, because there are multiple holes opened on the outside of the sponge box 26 and they are arranged in a staggered manner, the flow rate can be maximally increased, and the excess inorganic solution is re-discharged back into the pulp box 24.

[0043] Inside the body 1, there is an electric heating drying chamber 27 for drying the modified yarn after dyeing. The modified yarn guided by the guiding ring 25 will be wound around the machine inside the electric heating drying chamber 27, and then rotate to dry the yarn on it. The front end of the body 1 is fixedly connected with a lead frame 28 for guiding the dried yarn. The dried yarn after drying will be re-exported along with the rotating machine inside the electric heating drying chamber 27, and then be transmitted along the lead frame 28 here. The top end of the body 1 is fixedly connected with a winding machine 29 for collecting the dried yarn. A winding rod can be placed on the winding machine 29 here to recycle the modified and dried modified yarn.

[0044] A production method of an inorganic component-containing modified yarn, applicable to the above-mentioned production equipment of an inorganic component-containing modified yarn, includes the following steps:

[0045] S1. Adjustment: First, rotate the threaded rod 8 so that the moving box 9, the support rod 15, and the bottom box 18 move left and right accordingly. Repeat the operation three times so that the three bottom boxes 18 all move to appropriate positions, generally in a staggered position, with a general shape of a triangle, so as to achieve the purpose of tightening the passing yarn, reduce the situation of yarn knotting, and at the same time expand the coverage rate of the inorganic solution;

[0046] S2. Threading: Lift the top plate 20 so that there is a distance for the yarn to pass through between the pressing belt 1 21 and the pressing belt 2 22. Then pass the yarn on the feeding roller 4 through multiple bottom boxes 18. At this time, the yarn will be dyed by the inorganic solution inside the pulp box 24. Then pass the yarn through the sponge box 26 so that the sponge inside it wipes the excess inorganic solution on the yarn clean. Then enter the inside of the electric heating drying chamber 27 along the guiding ring 25, wind it around the rotating machine inside, and then pass the yarn through the lead frame 28 again, and fix the yarn head on the discharging roller on the winding machine 29. At this time, the entire body 1 can be started to perform the inorganic solution modification operation of the yarn;

[0047] S3. Cleaning: When it is necessary to modify the yarn with a new inorganic solution, the pressing plate 10 can be lifted first. At this time, the rubber strip 11 will cancel the engagement with the inner wall of the moving box 9 (because the rubber strip 11 itself is elastic, it will be first squeezed and deformed, and then return to its original state after disengaging from the engagement with the moving box 9). At the same time, the bottom end of the pressing plate 10 will no longer restrict the hook plate 12. At this time, the hook plate 12 will be naturally vertical under the influence of the gravity of the counterweight 13, so as to disengage from the engagement with the card slot 16. At this time, the support rod 15 can be taken out and its bottom box 18 can be cleaned. In addition, a plurality of holes are provided on the surfaces of the bottom box 18, the extrusion belt 1 21 and the extrusion belt 2 22. The holes here can discharge the excess or even deposited inorganic solution to prevent waste. After cleaning, insert the support rod 15 into the inside of the moving box 9, and at the same time observe from the top end of the pressing plate 10. It can be seen that the sequin 17 means that the support rod 15 here is close to the vertical state. Then press the pressing plate 10 to make the rubber strip 11 engage with the moving box 9 again, and the hook plate 12 engage with the card slot 16 again.

[0048] Working principle: Before the equipment is started, the operator first places the yarn roller to be modified on the support block 3 of the feeding assembly, and fixes the feeding roller 4 through the block 6 connected by the elastic traction rope 5 to prevent it from falling off accidentally; then adjusts the threaded rod 8 on the bracket 7 to drive the moving box 9 to move horizontally, so that the three bottom boxes 18 are distributed in a triangular staggered manner to optimize the yarn tension and expand the coverage range of the inorganic solution; when threading, the operator lifts the top plate 20 to separate the extrusion belt 1 21 from the extrusion belt 2 22 to form a channel, and passes the yarn through the three bottom boxes 18 in sequence. At this time, the tension of the spring 23 makes the extrusion belt 1 21 and the extrusion belt 2 22 reset and apply uniform pressure to the yarn, squeezing out the air inside the yarn and enhancing the subsequent penetration effect of the inorganic solution; the yarn then immerses in the inorganic solution in the slurry box 24 to complete the modification, and then the sponge in the sponge box 26 adsorbs the excess solution (the excess liquid flows back to the slurry box 24 through the holes in the sponge box 26), and is guided by the guiding ring 25 to the electric heating drying room 27 for drying, and finally winds around the winding machine 29 through the threading frame 28 to complete the collection.

[0049] When it is necessary to replace the inorganic solution or clean, the operator pulls up the pressing plate 10, and the bottom end thereof disengages from the restriction of the hook plate 12. The counterweight 13 causes the hook plate 12 to droop naturally and disengage from the card slot 16 of the support rod 15. At this time, the support rod 15 and the bottom box 18 can be taken out for thorough cleaning. The sequins 17 of the support rod 15 provide a visual cue for the vertical state to ensure accurate positioning during reinstallation. After the pressing plate 10 is pressed down, it is clamped and fixed with the moving box 9 through the rubber strip 11. At the same time, the hook plate 12 is reinserted into the card slot 16 to lock the support rod 15. During the whole process, the linear motion of the moving box 9 is guided by the fixed rod 14 to ensure stability. The hole design on the surfaces of the extrusion belt one 21 and the extrusion belt two 22 avoids solution deposition. The elastic traction rope 5 of the feeding assembly, the closed-loop solution recovery system of the pulp box 24, and the high-efficiency drying of the electric heating drying room 27 work together to achieve the efficient modification of the whole process of the yarn from dyeing, extrusion, liquid removal to drying, and finally improve the modification uniformity and finished product quality of the yarn.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
