[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention colors by putting the dye into the coloring chamber, pulling the polytetrafluoroethylene sewing thread below the liquid level of the dye and then pulling it out, and then pulling it below the liquid level again. Compared with the usual method of spraying the dye on the polytetrafluoroethylene sewing thread with a nozzle for coloring, it can make the dye fully penetrate into the interior of the sewing thread better and ensure that the outer surface of the sewing thread is fully adhered with the dye.

[0018] 2. By setting the scraping mechanism in the present invention, since the sewing thread moves through the second round sleeve, when the sewing thread with clots and a relatively thick layer of adhered dye passes through the second round sleeve, it will be blocked by the scraping knife.

[0019] 3. By setting the pretreatment mechanism in the present invention, the brush in the first round sleeve will first remove the dust on the sewing thread to prevent the dust from hindering the adhesion of the dye to the sewing thread. At the same time, the rotating arm will drive the brush head to contact the sodium naphthalene solution on the placing plate, and make the sodium naphthalene solution react with the polytetrafluoroethylene sewing thread at the bottom of the first collar, so that active groups are formed on its surface, enhancing the binding force with the dye, and thus making the dye more fully adhered to the sewing thread.

[0020] 4. By providing a thread take-up mechanism, the sliding block moves along the lead screw, causing the sewing thread passing through the ring to move horizontally. Along with the rotating rod, the sewing thread is evenly wound around the rotating rod and separated by the spiral groove, preventing the sewing thread from sticking together.

[0021] 5. The heating device of the present invention heats the air and flows out through the intake round holes and the air outlet holes, thereby further drying the sewing thread and preventing the sewing thread from adhering to the rotating rod or the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0038] Example 1, use Figures 1 - 14 A polytetrafluoroethylene sewing thread coloring device according to an embodiment of the present invention will be described as follows.

[0039] As Figures 1 - 3As shown in the figure, a coloring device for polytetrafluoroethylene sewing thread of the present invention includes a bottom plate 1. A thread spool bracket 1 is fixedly connected to the top of the bottom plate 1. A winding shaft is rotatably connected to the top of the thread spool bracket 1. A coloring mechanism 4 is fixedly connected to the middle of the bottom plate 1. A thread take-up mechanism 7 is fixedly connected to one end of the bottom plate 1 away from the thread spool bracket 1. A drying mechanism 5 is fixedly connected to one end of the coloring mechanism 4 close to the thread take-up mechanism 7. A pretreatment mechanism 6 is fixedly connected to one end of the coloring mechanism 4 close to the winding shaft 3;

[0040] When the present invention works, first, the polytetrafluoroethylene sewing thread is placed on the winding shaft, the pretreatment mechanism 6, the coloring mechanism 4, the drying mechanism 5 and the thread take-up mechanism 7 at specific positions. Then, the thread take-up mechanism 7 will start to pull the sewing thread and make the pretreatment mechanism 6 clean and apply the polytetrafluoroethylene sewing thread. After that, the coloring mechanism 4 and the drying mechanism 5 will color and dry it. Finally, the thread take-up mechanism 7 will orderly wind the colored sewing thread.

[0041] As Figure 7 shown, the coloring mechanism 4 includes a coloring chamber 41. A top cover 42 is placed on the top of the coloring chamber 41. A rotating column 43 is rotatably connected to the bottom of the coloring chamber 41. Stirring plates 44 are uniformly arranged on the outer surface of the rotating column 43. Support columns 45 are uniformly arranged on the inner wall of the coloring chamber 41. A collar 46 is rotatably connected to the outer surface of the support column 45. A scraping mechanism 47 is fixedly connected to the outer surface of the support column 45 away from the pretreatment mechanism 6;

[0042] Place specific dyes in the coloring chamber 41. Due to the position limitation of the three support columns 45 and the collar 46, the support columns 45 on both sides are below the liquid level. The polytetrafluoroethylene sewing thread is pulled into the dye liquid level and then pulled out, and then pulled into the liquid level again for coloring. Compared with the usual method of spraying the dye on the polytetrafluoroethylene sewing thread with a nozzle for coloring, this method can better make the dye fully penetrate into the interior of the sewing thread and ensure that the outer surface of the sewing thread is fully adhered with the dye. At the same time, the servo motor 672 will drive the motor shaft 673 to rotate and further drive the rotating column 43 to rotate, thereby preventing the formation of clots in the dye and ensuring the flow of the dye, making the dye more evenly distributed in each part of the sewing thread, so as to avoid the situation of over-dark or over-light local dyeing.

[0043] As Figures 8 - 9As shown, the scraping mechanism 47 includes a third support rod 471. One end of the third support rod 471 away from the second support column 45 is fixedly connected with a second circular sleeve 472. The inner wall of the second circular sleeve 472 is slidably connected with a sliding circular plate 473. A pull rope 474 is fixedly connected to the outer surface of the sliding circular plate 473. A scraping knife 475 is fixedly connected to the inner wall of the sliding circular plate 473. The bottom of the second circular sleeve 472 is fixedly connected with a fixing ring 476. One end of the fixing ring 476 close to the sliding circular plate 473 is fixedly connected with a telescopic spring 477. The top of the telescopic spring 477 is fixedly connected with a blocking block 478. The top of the blocking block 478 is in contact with the bottom of the sliding circular plate 473.

[0044] After the sewing thread first enters below the liquid level of the dye, due to the different thicknesses of the dye adhered and the possible presence of relatively large clots in the dye, these clots will also adhere to the surface of the sewing thread. Since the sewing thread moves through the second circular sleeve 472, when the sewing thread with adhered clots and relatively thick adhered dye passes through the second circular sleeve 472, it will be blocked by the scraping knife 475. The telescopic spring 477 and the blocking block 478 at the bottom will block the downward movement of the sliding circular plate 473. When the sliding circular plate 473 is pulled out by stretching, the clots falling on the sliding circular plate 473 can be taken out, avoiding the excessive clots from hindering the movement of the sewing thread.

[0045] The bottom of the coloring bin 41 is fixedly connected with the top of the bottom plate 1. The bottom of the third support rod 471 is fixedly connected with the outer surface of the second support column 45 away from the pretreatment mechanism 6.

[0046] As Figures 4 - 5 shown, the pretreatment mechanism 6 includes a first support plate 61. A first support column 62 is fixedly connected to the top of the first support plate 61. A second support plate 64 is fixedly connected to the outer surface of the first support plate 61. A first rotating shaft 65 is rotatably connected to the top of the second support plate 64. A first ring 66 is fixedly connected to the top of the first rotating shaft 65. A coating mechanism 67 is arranged at the bottom of the coloring bin 41. One end of the second support plate 64 close to the first support plate 61 is fixedly connected with a first support rod 68. A first circular sleeve 69 is fixedly connected to the top of the first support rod 68. Brushes 610 are evenly arranged on the inner wall of the first circular sleeve 69.

[0047] The polytetrafluoroethylene sewing thread will pass through the first ring 66 and the first circular sleeve 69 and be sleeved on the first collar 63. Before the sewing thread is pulled into the dye, the brushes 610 in the first circular sleeve 69 will first remove the dust on the sewing thread, preventing the dust from hindering the dye from adhering to the sewing thread.

[0048] As Figure 6As shown, the coating mechanism 67 includes a support foot 671. At the top of the support foot 671, a first servo motor 672 is fixedly connected. At the output end of the first servo motor 672, a first motor rotating shaft 673 is fixedly connected. On the outer surface of the first motor rotating shaft 673, a first disc 674 is fixedly connected. The first motor rotating shaft 673 penetrates the outer surface of the coloring bin 41 and extends to the inner wall. A track 675 is sleeved on the outer surface of the first disc 674. A second rotating shaft 676 is rotatably connected to the top of the coloring bin 41. On the outer surface of the second rotating shaft 676, a second disc 677 is fixedly connected. The outer surface of the second disc 677 is sleeved with the track 675. At one end of the second rotating shaft 676 away from the second disc 677, a rotating arm 678 is fixedly connected. At one end of the rotating arm 678 away from the second rotating shaft 676, a brush head 679 is fixedly connected. A second support rod 6710 is fixedly connected to the outer surface of the coloring bin 41. At one end of the second support rod 6710 away from the coloring bin 41, a placement plate 6711 is fixedly connected. The placement plate 6711 is located below the rotating arm 678.

[0049] Polytetrafluoroethylene has an extremely low surface energy, which makes it difficult for dyes to adhere firmly to its surface. Even after soaking in the dye solution, problems such as poor coloring fastness and easy fading may occur.

[0050] The first motor rotating shaft 673 will also drive the second disc 677 to rotate. Through the transmission of the track 675 and the second disc, the second rotating shaft 676 will rotate, and the rotating arm 678 will drive the brush head 679 to contact the sodium naphthalene solution on the placement plate 6711, and the sodium naphthalene solution will react with the polytetrafluoroethylene sewing thread at the bottom of the first collar 63, forming active groups on its surface and enhancing the binding force with the dye, so that the dye adheres more fully to the sewing thread.

[0051] The bottom of the first support plate 61 is fixedly connected to the outer surface of the coloring bin 41. The bottom of the support foot 671 is fixedly connected to the top of the bottom plate 1. One end of the first motor rotating shaft 673 away from the first servo motor 672 is fixedly connected to one end of the rotating column 43.

[0052] The specific working process is as follows:

[0053] During operation, the polytetrafluoroethylene sewing thread passes through the first ring 66 and the first sleeve 69 and is sleeved on the first collar 63. Before the sewing thread is pulled into the dye, the brush 610 in the first sleeve 69 first removes the dust on the sewing thread. The motor shaft 673 also drives the second disc 677 to rotate, and through the transmission of the crawler 675 and the second turntable, the second shaft 676 rotates, and the rotating arm 678 drives the brush head 679 to contact the sodium naphthalene solution on the placement plate 6711. Then, the polytetrafluoroethylene sewing thread is pulled below the dye liquid level and then pulled out, and then pulled below the liquid level again for coloring. At the same time, the first servo motor 672 drives the motor shaft 673 to rotate and further drives the rotating column 43 to rotate, thereby preventing the precipitation of clots in the dye and ensuring the flow of the dye.

[0054] Example 2, using Figures 1 - 14 A polytetrafluoroethylene sewing thread coloring device according to an embodiment of the present invention will be described as follows.

[0055] As Figure 10 As shown, a polytetrafluoroethylene sewing thread coloring device of the present invention, on the basis of Example 1, the drying mechanism 5 includes a third support plate 51, and the third support plate 51 is symmetrically arranged at one end of the coloring chamber 41 away from the pretreatment mechanism 6. The opposite surfaces of the third support plate 51 are rotatably connected with third support columns 52. The top of the third support plate 51 is fixedly connected with a top rod 53. One end of the top rod 53 away from the third support plate 51 is fixedly connected with a drying chamber 54. An inlet 56 is arranged on the drying chamber 54, and a drying device 55 is fixedly connected to the outer surface of the drying chamber 54.

[0056] The bottom of the third support plate 51 is fixedly connected to the outer surface of the coloring chamber 41. The number of inlets 56 is two and their positions are one high and one low.

[0057] After the sewing thread passes through the drying chamber 54, the drying device 55 raises the temperature in the drying chamber 54, thereby drying the sewing thread.

[0058] As Figures 11 - 12 As shown, the wire winding mechanism 7 includes a second wire spool bracket 71. A heating device 72 is fixedly connected to the outer surface of the second wire spool bracket 71. A collecting plate 73 is fixedly connected to the bottom of the second wire spool bracket 71. One end of the second wire spool bracket 71 away from the heating device 72 is fixedly connected to a support bottom plate 74. A second servo motor 75 is fixedly connected to the top of the support bottom plate 74. The output end of the second servo motor 75 is fixedly connected to a motor shaft 76. A first gear 77 is fixedly connected to the outer surface of the motor shaft 76. One end of the motor shaft 76 is fixedly connected to a winding mechanism 78. A second gear 79 is rotatably connected to one side of the second wire spool bracket 71 close to the first gear 77.

[0059] As Figures 13 - 14As shown, the winding mechanism 78 includes a rotating rod 781. A spiral groove 782 is fixedly connected to the outer surface of the rotating rod 781. An air inlet round hole 783 is provided inside the rotating rod 781. Air outlet holes 784 are evenly arranged on the outer surface of the spiral groove 782. A lead screw 785 is fixedly connected to the outer surface of the second gear 79. A sliding block 786 is threadedly connected to the outer surface of the lead screw 785. A second ring 787 is fixedly connected to the top of the sliding block 786. A hanging plate 788 is fixedly connected to the bottom of the sliding block 786. An expansion link 789 is fixedly connected to the bottom of the hanging plate 788. A brush plate 7810 is fixedly connected to the top of the expansion link 789. Fixed ends 7811 are provided at both ends of the rotating rod 781.

[0060] One end of the polytetrafluoroethylene sewing thread is fixed to the fixed end 7811 of the rotating rod 781. Then, the second servo motor 75 drives the second motor rotating shaft 76 to rotate, thereby driving the rotating rod 781 to rotate, so as to realize the winding of the colored sewing thread. The second motor rotating shaft 76 drives the first gear 77 to rotate, thereby driving the second gear 79 and the lead screw 785 to rotate and finally making the sliding block 786 move along the lead screw 785, so that the sewing thread passing through the second ring 787 moves horizontally. Along with the rotation of the rotating rod 781, the sewing thread is evenly wound on the rotating rod 781 and separated by the spiral groove 782 to prevent the sewing thread from sticking. At the same time, the heating device 72 heats the air and the hot air flows out through the air inlet round hole 783 and the air outlet holes 784, so as to further dry the sewing thread and prevent the sewing thread from adhering to the rotating rod 781 or the spiral groove 782. Along with the movement of the sliding block 786 and the adjustment of the height of the expansion link 789, the brush plate 7810 brushes the sewing thread, further improving the surface after coloring and removing the dust falling on the sewing thread from the air.

[0061] The bottom of the second spool bracket 71 is fixedly connected to the top of the bottom plate 1. One end of the rotating rod 781 is fixedly connected to the outer surface of the first gear 77.

[0062] The specific working process is as follows:

[0063] During operation, after the sewing thread passes through the drying bin 54, the drying device 55 raises the temperature inside the drying bin 54, and then dries the sewing thread. After that, the second servo motor 75 drives the second motor shaft 76 to rotate, which in turn drives the rotating rod 781 to rotate, thereby realizing the winding of the colored sewing thread. The lead screw 785 rotates and finally makes the slider 786 move along the lead screw 785, so that the sewing thread passing through the second ring 787 moves horizontally. Along with the rotating rod 781, the sewing thread is evenly wound around the rotating rod 781 and separated by the spiral groove 782. At the same time, the heating device 72 heats the air and flows out through the intake round hole 783 and the air outlet hole 784, thereby realizing further drying of the sewing thread and preventing the sewing thread from adhering to the rotating rod 781 or the rotating rod 781.
