Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn multi-strand doubling and twisting mechanism. Background Art

[0002] When the yarn is processed, multiple yarns are twisted. The twisting is achieved through a twisting mechanism. When twisting, the silk thread passes through the guide and the unwinding device in turn, and is finally wound around the spindle. During use, sensor one and sensor two are used to monitor whether the silk thread is broken.

[0003] After searching, the Chinese utility model patent with announcement number CN210194076U discloses a multi-strand yarn twisting mechanism, which involves the field of textile machinery technology. The key points of its technical solution are: including a yarn rack, a support rod, a decoupling device, a broken wire detection device, a spindle, and a controller. The single yarn on the yarn rack bypasses the support rod and turns to the decoupling device. The decoupling device drives the single yarn to feed toward the spindle. After each single yarn is combined into one strand, the spindle twists the multiple strands of yarn into finished yarn. The broken wire detection device on the yarn rack is used to detect whether the single yarn is broken. After the detection device detects that the yarn is broken, it will emit an electrical signal to the outside. After the controller set on the yarn rack receives the electrical signal sent by the broken wire detection device, it will shut down the working decoupling device and the spindle. After the staff has handled the broken yarn, the twisting mechanism will be started, which solves the technical problem that the yarn is easy to lack strands after twisting.

[0004] In the above patent, the yarn drum is inserted into the fixed shaft, and the yarn drum and the fixed shaft are fixed by a spring sheet. The elastic force of the spring sheet is limited. During rotation, the yarn drum and the fixed shaft will rotate, resulting in reduced product quality. Therefore, the present application provides a multi-strand yarn twisting mechanism to meet the needs. Utility Model Content

[0030] The fixing assembly 9 includes a fixing shaft 901 rotatably connected to the fixing frame 2, an inner cavity 902 is provided inside the fixing shaft 901, a through hole 904 connected to the inner cavity 902 is provided on the surface of the fixing shaft 901, a rubber sheet 905 is fixed to the inner wall of the through hole 904, a round hole 903 connected to the inner cavity 902 is provided at one end of the fixing shaft 901 away from the fixing frame 2, a piston 906 is slidably connected to the inner wall of the inner cavity 902, a connecting rod 907 is fixed to the end of the piston 906 away from the fixing frame 2, an inner thread ring 910 is fixed to the inner wall of the inner cavity 902, and the inner thread ring 910 is fixed to the inner wall of the inner cavity 902. 10 is threadedly connected to the surface of the connecting rod 907, and a square hole 908 is opened at the end of the connecting rod 907 away from the piston 906, and a square rod 909 is movably inserted into the inner wall of the square hole 908. The square rod 909 passes through the round hole 903 and is fixed with a handle 912. The space formed by the side of the piston 906 away from the connecting rod 907 and the inner cavity 902 is filled with hydraulic oil. When the piston 906 moves toward the fixing frame 2, the pressure in the inner cavity 902 on the side of the piston 906 close to the fixing frame 2 increases, and the pressure expands the rubber sheet 905 on the inner wall of the yarn tube 8, thereby fixing the yarn tube 8.

[0031] like Figure 2 As shown, in this embodiment, an anti-skid groove is provided on the surface of the handle 912 to increase the friction between the fingers and the handle 912 and prevent the fingers and the handle 912 from sliding.

[0032] like Figure 3As shown, in this embodiment, a limiting ring 911 is provided on the surface of the connecting rod 907 . When in use, the limiting ring 911 fits against the side of the internal thread ring 910 to prevent the connecting rod 907 from moving too far toward the inner wall of the inner cavity 902 .

[0033] like Figure 3 As shown, in this embodiment, the circle of the limiting ring 911 coincides with the center of the connecting rod 907, making the rotation more stable.

The positioning rod 914 with the curved surface at the end is easier to insert into the positioning hole 913.

[0037] like Figure 3 As shown, in this embodiment, the positioning rod 914 is a magnetic rod, and the magnetic force between the positioning rod 914 and the fixed shaft 901 fixes the handle 912 to prevent the handle 912 from rotating during use.

[0038] Working principle: before use, insert the yarn tube 8 on the fixed shaft 901, hold the fixed shaft 901 to prevent the fixed shaft 901 from rotating, then hold the handle 912 with your hand, turn the handle 912, the handle 912 drives the square rod 909 to rotate, the square rod 909 drives the connecting rod 907 to rotate, the connecting rod 907 rotates on the inner wall of the internal thread ring 910, the connecting rod 907 will move in the direction of the fixed frame 2, so that the piston 906 is close to the fixed frame 2, and the space pressure of the inner cavity 902 increases, and the pressure increases. After adding, the rubber sheet 905 in the through hole 904 is expanded, and the rubber sheet 905 will fit the inner wall of the yarn tube 8 to fix the yarn tube 8. Then the handle 912 is moved in the direction of the fixed axis 901, and the positioning rod 914 on the handle 912 is inserted into the positioning hole 913 to fix the handle 912. After the handle 912 is fixed, the square rod 909 and the connecting rod 907 are fixed to prevent the connecting rod 907 from rotating during use, thereby improving the overall stability. After that, the silk thread can be twisted.
