[0026] like Figures 1-8As shown, a heating plate 21, a stretching plate 30, a cooling plate 40, and two first support rods 12 are sequentially fixed on the base plate 11. The first support rods 12 are rotatably connected to a drive roller 13, which is electrically connected to a drive source. The heating plate 21 has a first opening 22, the stretching plate 30 has a first slot 31, and the cooling plate 40 has a third opening 41. The mixed fiber 14 passes through the first opening 22, the first slot 31, and the third opening 41 and is wound around the outer surface of the drive roller 13. A heating component is provided inside the heating plate 21, a stretching component is provided inside the stretching plate 30, and a cooling mechanism is provided inside the cooling plate 40. The cooling mechanism includes an adjustment component, and a transmission belt 19 is provided between the adjustment component and the stretching component. The transmission belt 19 is used to maintain the adjustment component and the stretching component at the same frequency.

[0027] It is worth noting that a network composite plate 51 is provided between the cooling plate 40 and the first support rod 12. A network composite air passage 52 is provided on the network composite plate 51. A network composite nozzle for changing the composite network of the mixed fiber 14 is provided in the network composite air passage 52. The network air pressure in the air passage of the network composite nozzle is controlled by the closing of a solenoid valve. The closing of the solenoid valve is controlled by the program of the programmable controller, so that the fiber has a certain open section without a network.

[0028] The heating assembly includes a heating ingot 24, and a heating chamber 23 is provided on the heating plate 21. The heating ingot 24 is detachably connected to the heating chamber 23. The heating chamber 23 is provided close to the heating plate 21. The first opening 22 and the third opening 41 are both circular openings. The axes of the first opening 22 and the third opening 41 coincide. The axis of the first opening 22 passes through the axis of the arc surface at one end of the first slot 31. The width of the first slot 31 is greater than the diameter of the mixed fiber 14.

[0029] The tensioning assembly includes a first sliding plate 34 and a first gear 37. A second opening 32 and a first sliding cavity 33 are formed within the tensioning plate 30. The second opening 32 passes through the tensioning plate 30 and connects to the first sliding cavity 33. A second slot 35 is formed on the first sliding plate 34, which is slidably connected to the first sliding cavity 33. A third slot 36 is formed at one end of the first sliding plate 34 near the pulley assembly. A first toothed belt 38 is fixedly connected within the third slot 36, and the first toothed belt 38 engages with a first tooth. A first transmission rod 16 is rotatably connected to a wheel 37 and a second opening 32. A first gear 37 is fixedly connected to the first transmission rod 16. A transmission belt 19 is sleeved on the first transmission rod 16. A drive motor 15 is rotatably connected to the first transmission rod 16. A second support rod 20 is fixedly connected to the side of the drive motor 15 near the tension plate 30. The second support rod 20 is fixedly connected to the tension plate 30. The second slot 35 and the first slot 31 are set at the same horizontal height. The first sliding plate 34 is adapted to the first slot 31.

[0030] It is worth noting that in order to enhance the stretching effect of the stretching assembly on the mixed yarn 14, a guide is usually fixed at one end of the first slot 31, and the corresponding 14 passes through the guide.

[0031] The cooling mechanism further includes a cooler 43 fixedly arranged in the second sliding cavity 42, and the cooler 43 is fixedly connected with a cooler nozzle 44. The adjusting assembly includes a second sliding plate 45 and a second gear 48. The second sliding plate 45 is provided with a fourth opening 46, and one end of the second sliding plate 45 is provided with a fourth slot 47. A second tooth belt 49 is fixedly arranged on one side wall of the fourth slot 47. The second gear 48 is engaged with the second tooth belt 49. The second gear 48 is fixedly connected with a second transmission rod 18. The second transmission rod 18 penetrates through the second sliding plate 45 and is fixedly connected with a pulley 17. A transmission belt 19 is sleeved on the outer circular surface of the pulley 17. The radius of the pulley 17 is greater than the radius of the first transmission rod 16. The radius of the fourth opening 46 is greater than the outlet of the cooler nozzle 44.

[0032] It is worth noting that in order to ensure that the stretching and elasticizing frequency of the second slot 35 on the mixed yarn 14 is the same as the limiting frequency of the cooler nozzle 44 by the fourth opening 46, the ratio of the outer circular surface length of the pulley 17 to the outer circular surface length of the first transmission rod 16 is equal to the ratio of the length of the first slot 31 to the diameter of the fourth opening 46, and the diameter of the first gear 37 is equal to the diameter of the second gear 48, thereby ensuring that the cooling efficiency corresponds to the thick and thin sections generated by the neck stretching.

[0033] When the present scheme is used for mixed yarn elasticizing, first, the mixed yarn 14 passes through the first opening 22, passes out of the third opening 41 after passing through the first slot 31, and is wound on the outer circular surface of the driving roller 13. The driving source drives the driving roller 13 to rotate, and the driving roller 13 winds the mixed yarn 14 to move in the direction of the driving roller 13. When the mixed yarn 14 passes through the first opening 22, the hot ingot 24 conducts heat to the mixed yarn 14 in the first opening 22 to heat the mixed yarn 14.

[0034] Then, when the driving source drives the driving roller 13 to rotate, the output shaft of the driving motor 15 drives the first transmission rod 16 to rotate relative to the second opening 32. The first transmission rod 16 drives the first gear 37 to rotate. Since the first gear 37 is engaged with the first tooth belt 38, the first gear 37 drives the first tooth belt 38 to drive the first sliding plate 34 to slide along the first sliding cavity 33. The second slot 35 slides relative to the first slot 31. The second slot 35 pushes the mixed yarn 14 away from one end of the first slot 31, so that the mixed yarn 14 is lengthened, thereby forming a neck stretch between the first opening 22 and the third opening 41.

[0035] When the output shaft of the driving motor 15 drives the first transmission rod 16 to rotate, the outer circular surface of the first transmission rod 16 drives the transmission belt 19 to rotate, the transmission belt 19 drives the pulley 17 to rotate, the pulley 17 drives the second gear 48 to rotate through the second transmission rod 18, since the second gear 48 is engaged with the second tooth belt 49, thus the second gear 48 drives the second sliding plate 45 to slide in the second sliding cavity 42, so that the fourth opening 46 slides relative to the cooler nozzle 44, changes the size of the outlet of the cooler nozzle 44, thus changes the cooling effect on the mixed fiber 14.

[0036] Finally, after the fine neck stretching forms the thick and thin section, the mixed fiber 14 enters the network composite air channel 52, the opening and closing of the network mixed fiber composite nozzle air pressure in the network composite air channel 52 is controlled by the switch of the electromagnetic valve, the switch of the electromagnetic valve is controlled by the program of the programmable controller, so that the fiber has a certain non-network opening section, so that a plurality of mixed fibers 14 are mixed into one, the mixed fiber 14 in the network composite air channel 52 is wound on the driving roller 13.

[0037] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application is defined by the appended claims and their equivalents.
