[0015] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figs. 1-3 As shown, this utility model is a yarn limiting device.

[0017] The yarn limiting device described in this embodiment includes a yarn 1 and an electric cleaning device 3. The electric cleaning device 3 has a detection area 31 for detecting knots in the yarn 1. A limiting mechanism 2 is provided on the upper side of the detection area 31 for limiting the yarn 1. The limiting mechanism 2 includes a yarn-blocking rod seat 7 disposed above the electric cleaning device 3. The yarn-blocking rod seat 7 has a through channel perpendicular to the yarn 1. The channel has a two-section structure, with the protruding end being smaller than the non-protruding end. At the same time, the protruding end of the yarn-blocking rod 4 is smaller than the dimensions of the other sections. The yarn-blocking rod 4 is disposed in the through channel and is slidably connected to the yarn-blocking rod seat 7. One end of the yarn-blocking rod 4 is driven by a power mechanism to extend into the yarn channel and block the yarn 1. After detection, it is pulled back to its original position by a return mechanism. The yarn-blocking rod 4 is sealed to the yarn-blocking rod seat 7 by a sealing mechanism. The yarn-blocking rod 4 has a cylindrical structure and is loosely connected to the yarn-blocking rod seat 7 to ensure flexible sliding.

[0018] Furthermore, the power mechanism is a pipe connector 8 that connects to high-pressure air, and the pipe connector 8 is equipped with an O-ring that seals with the yarn-blocking rod seat 7.

[0019] Furthermore, the return mechanism is a spring 5, which is sleeved on the yarn-blocking rod seat 7 at the extended end. When the yarn-blocking rod 4 extends, it compresses the spring 5, and when the spring 5 returns, it pulls the yarn-blocking rod 4 back to its original position.

[0020] Furthermore, the sealing mechanism is a Y-shaped sealing ring 6.

[0021] Furthermore, the yarn-blocking rod 4 has a guide section 43 at one end and an arc-shaped protrusion 41 at the extended end. The guide section 43 has a tapered structure, and the end dimension of the tapered structure is smaller than the inner hole dimension of the yarn-blocking rod seat 4. The arc-shaped protrusion 41 will not damage the yarn 1.

[0022] Furthermore, a groove 42 is provided on one side of the guide section 43. The groove 42 is a cylindrical section with a smaller size than other sections, and the groove 42 is connected to the Y-shaped sealing ring 6.

[0023] When this yarn limiting device is in use, it is installed above the electronic speed cutter. After the yarn is caught in the splicer, high-pressure air pushes out the yarn-stopping rod through the air pipe connector. After the splicer completes the knotting action, the yarn catcher releases, and the yarn leaves the splicing chamber under tension. The presence of the yarn-stopping rod ensures that the yarn maintains a certain tension while remaining within the electronic speed cutter's detection area, preventing vibration or slippage. After the electronic speed cutter completes the yarn splice detection, the high-pressure air supply stops, and the yarn-stopping rod returns to its original position under the action of a spring. The electronic speed cutter and splicer retract simultaneously. Without the obstruction of the yarn-stopping rod, the yarn returns to the spinning channel and begins normal spinning.

[0024] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model. Any modifications and improvements made by those skilled in the art based on the design concept of the present utility model should be considered within the scope of protection of the present utility model.
