Detailed implementation manners

[0019] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown, a stretching device for highly elastic spinning includes an unwinding device, a processing box 3, and a winding device 21. The unwinding device includes an unwinding roller 2. The processing box 3 has a feed inlet 31 and a discharge outlet 32. Inside the processing box 3, a first guide roller 41, a spraying mechanism, a second guide roller 42, a tensioning mechanism, a heating and shaping mechanism, and a third guide roller 43 are sequentially installed from left to right. The winding device 21 is installed on the right side of the processing box 3 for winding.

[0021] Both sides of the processing box 3 have sliding holes 33. The tensioning mechanism includes hydraulic cylinders 51, first mounting plates 52, second mounting plates 53, driving motors 54, and tensioning rollers 55 installed on the front and rear sides of the processing box 3. First mounting plates 52 are fixed on the piston rods of the hydraulic cylinders 51. Second mounting plates 53 are installed on the first mounting plates 52. A driving motor 54 is installed on one side of the second mounting plate 53. The output shaft of the driving motor 54 passes through the sliding hole 33, and a tensioning roller 55 for stretching the spinning is drivingly connected to the output shaft.

[0022] A third mounting plate 61 is also installed in the processing box 3. The heat setting mechanism includes a lifting motor 62, a lifting frame 63, a first heating roller 64, a second heating roller 65 and a setting roller 66. The first heating roller 64 and the second heating roller 65 are sequentially installed in the processing box 3 from left to right. The first heating roller 64 is located on the right side of the tension roller 55. A lifting motor 62 is installed in the processing box 3. The lifting rod of the lifting motor 62 sequentially passes through the processing box 3 and the third mounting plate 61 and is connected to the lifting frame 63. A setting roller 66 is installed on the lifting frame 63. A second heating roller 65 is provided directly below the setting roller 66.

[0023] In the present utility model, the first heating roller 64 and the second heating roller 65 are prior arts.

[0024] With the above structure, the spinning is released from the unwinding roller 2. Then, after the spinning passes through the feed port 31 of the processing box 3, it is guided by the first guide roller 41 and the second guide roller 42 to the position of the tensioning mechanism. The guiding of the spinning by the first guide roller 41 and the second guide roller 42 is beneficial to better maintain the conveying direction of the spinning. The hydraulic cylinder 51 drives the second mounting plate 53 to move up or down, and at the same time, the driving motor 54 drives the tension roller 55 to enable the spinning to be stretched slightly, improving the elasticity of the spinning. Then, it is preheated by passing through the first heating roller 64 and then conveyed to the lower part of the setting roller 66 for setting treatment of the spinning. The setting roller 66 can be moved above the spinning by the lifting motor 62 to set the spinning. At the same time of setting, a second heating roller 65 capable of heating the spinning is also installed below the spinning, further strengthening the elasticity of the spinning and preventing the sliding of the spinning during stretching. After the spinning is set, it is conveyed out of the discharge port 32 by the third guide roller 43 and finally wound by the winding device 21.

[0025] The setting of this structure is beneficial to adjust the height of the tension roller 55 in real time by setting a tension roller 55 that can be flexibly adjusted up and down and preheating the spinning before setting the spinning, enabling the spinning to always perform high-quality tension stretching operations, with stronger practicability. Through preheating and continuous heating during setting, the preheating is sufficient, which is beneficial to further strengthen the elasticity of the spinning, prevent the sliding of the spinning during stretching, reduce the generation of fuzz and broken ends during stretching, and improve the stretching performance.

[0026] Specifically, as Figures 1 to 5 shown, the spraying mechanism includes a liquid storage tank 71, a spraying frame 72 and a plurality of spray heads 73. The liquid storage tank 71 is installed on the processing box 3. The liquid storage tank 71 is connected to the spraying frame 72. A plurality of spray heads 73 are arranged on the spraying frame 72, and the spray heads 73 are aligned with the position of the spinning directly below.

[0027] With the above structure, by providing a spraying mechanism before tension stretching spinning, the spray head 73 can perform liquid spraying treatment on the spun yarn, which is beneficial to having good cohesion, reducing the phenomenon of hairiness, preventing hairiness and breakage during stretching, and improving the stretching performance.

[0028] As Figures 1 to 5 shown, a water collecting tank 81 is further opened at the bottom of the processing tank 3, and a drain pipe 82 is opened on one side of the water collecting tank 81.

[0029] By providing the water collecting tank 81 and the drain pipe 82, it is beneficial to collect the water sprayed by the spraying mechanism and discharge it from the inside of the processing tank 3, which is beneficial to preventing the processing tank 3 from accumulating too much liquid, resulting in the inside of the processing tank 3 being unclean and making it cleaner and unobstructed.

[0030] As Figures 1 to 5 shown, the shaping roller 66 is located directly above the second heating roller 65, the shaping roller 66 abuts against the upper surface of the spun yarn, and the second heating roller 65 abuts against the lower surface of the spun yarn.

[0031] By continuously heating while performing shaping stretching, with sufficient preheating, it is beneficial to further enhance the elasticity of the spun yarn, prevent the sliding of the spun yarn during stretching, reduce hairiness and breakage during stretching, and improve the stretching performance.

[0032] As Figures 1 to 5 shown, a compression spring 631 is further provided inside the lifting frame 63. One end of the compression spring 631 is fixedly connected to the inside of the lifting frame 63, and the other end is connected to the connecting column 632. A transmission rod 661 is provided on the shaping roller 66, and the connecting column 632 is fixed on the transmission rod 661 of the shaping roller 66.

[0033] In the present utility model, the compression spring 631 is a prior art.

[0034] By providing the compression spring 631, the height of the shaping roller 66 can be slightly adjusted during shaping, so that the shaping roller 66 is adjusted to a suitable position to adapt to the shaping operations of spun yarns of different sizes, with stronger practicability, better shaping effect and higher precision.

[0035] As Figures 1 to 5 shown, the first guide roller 41 and the second guide roller 42 are at the same height.
