DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a wire guide device for preparing core-spun yarn comprises a base 1, a vertical rod 2 is arranged on the base 1, a slot 3 is arranged on the vertical rod 2, a wire guide wheel 4 is arranged in the slot 3, a limiting assembly is arranged on the slot 3, the limiting assembly comprises a first limiting part and a second limiting part, the first limiting part and the second limiting part are respectively arranged on both sides of the upper end of the slot 3, the first limiting part comprises a first vertical plate 5, a limiting frame 6 is arranged on the upper end of the first vertical plate 5, a side of the limiting frame 6 close to the second limiting part is provided with an inclined surface for guiding, a fixed anti-slipping block 7 is arranged at the bottom of the limiting frame 6, a side of the fixed anti-slipping block 7 close to the second limiting part is located in the same plane as the inclined surface of the limiting frame 6, and the second limiting part comprises a first vertical plate 5, a limiting frame 6 is arranged on the upper end of the first vertical plate 5 ... The second vertical plate 8 is included, and a horizontal plate 9 is provided at the upper end of the second vertical plate 8. A slope is provided on one side of the horizontal plate 9 close to the limit frame 6. There is a gap between the slope on the horizontal plate 9 and the slope on the limit frame 6 for the silk thread 10 to pass through. A movable anti-slip block 11 is provided at the lower part of the horizontal plate 9. One end of the movable anti-slip block 11 is rotatably connected to the horizontal plate 9. A groove is provided inside the horizontal plate 9, and also includes an elastic rope 12. One end of the elastic rope 12 is fixedly connected to the inner top of the groove, and the other end of the elastic rope 12 is fixedly connected to the movable anti-slip block 11. An inclined surface is provided at one end of the movable anti-slip block 11 close to the fixed anti-slip block 7, and the inclined surface on the movable anti-slip block 11 and the inclined surface on the fixed anti-slip block 7 abut against each other.

[0017] When the thread 10 is hung on the wire guide wheel 4, the thread 10 needs to pass through the first limiting part and the second limiting part. First, the base 1 is fixed to the corresponding frame body by bolt connection, and then the thread 10 is pulled to pass through the gap between the cross plate 9 and the limit frame 6. When the thread 10 contacts the movable anti-slip block 11, the pressure of pulling the thread 10 will cause the movable anti-slip block 11 to rotate to a certain extent, so that a certain gap between the movable anti-slip block 11 and the fixed anti-slip block 7 is formed, so that the thread 10 can pass through the gap between the movable anti-slip block 11 and the fixed anti-slip block 7 and be hung on the wire guide wheel 4. After the thread 10 passes through the movable anti-slip block 11, under the action of the elastic rope 12, the movable anti-slip block 11 will be controlled to reset. After the movable anti-slip block 11 is reset, the inclined surface on the movable anti-slip block 11 and the inclined surface on the fixed anti-slip block 7 abut against each other, and the thread 10 cannot escape from the gap between the cross plate 9 and the limit frame 6.

[0018] The intervals between the two ends of the fixed anti-slip block 7 and the movable anti-slip block 11 that are far away from each other and the wire guide wheel 4 are very small, so the wire 10 can be effectively confined between the fixed anti-slip block 7, the movable anti-slip block 11 and the wire guide wheel 4.

[0019] Furthermore, the lower surfaces of the fixed anti-slip block 7 and the movable anti-slip block 11 are both provided with a row of teeth 13. When the wire 10 jumps on the guide wheel 4 and contacts the row of teeth 13, the existence of the row of teeth 13 will limit the movement of the wire 10 to the two sides of the row of teeth 13, and increase the resistance of the wire 10 to the movement of the two sides of the row of teeth 13, thereby effectively preventing the wire 10 from slipping off the guide wheel 4. The tooth in the row of teeth 13 closest to the slot 3 extends downward by a distance greater than the distance of the remaining teeth in the row of teeth 13 extending downward, which can further reduce the shortest distance between the row of teeth 13 and the guide wheel 4, thereby increasing the difficulty of the wire 10 slipping off the guide wheel 4.

[0020] Furthermore, the upper end surface of the horizontal plate 9 is provided with an arc surface 14, which is inclined downward and toward the end of the horizontal plate 9 close to the limit frame 6. When the wire 10 moves along the arc surface 14, the arc surface 14 can be used to guide the wire 10 to the position of the gap between the horizontal plate 9 and the limit frame 6, thereby reducing the difficulty of hanging the wire 10 and improving the hanging efficiency of the wire 10.

[0021] Furthermore, the height of the upper end of the limit frame 6 is higher than the height of the upper end of the horizontal plate 9. When the silk thread 10 passes through the horizontal plate 9, the limit frame 6 can limit the movement of the silk thread 10 to prevent the silk thread 10 from directly crossing the limit frame 6, thereby facilitating the silk thread 10 to enter the gap between the horizontal plate 9 and the limit frame 6 more accurately and stably.

[0022] Furthermore, the rows of teeth 13 on the fixed anti-slip block 7 and the movable anti-slip block 11 are both made of nylon plastic, which reduces the friction between the wire 10 and avoids the wire 10 from breaking due to the large friction when the wire 10 contacts the rows of teeth 13.

[0023] When the device is in use, the silk thread 10 can quickly pass through the gap between the cross plate 9 and the limit frame 6, and control the rotation of the movable anti-slip block 11, so that the silk thread 10 is hooked on the wire guide wheel 4. After the silk thread 10 is hooked on the wire guide wheel 4, the movable anti-slip block 11 is reset through the elastic rope 12, and in cooperation with the fixed anti-slip block 7, it can prevent the silk thread 10 from entering the gap between the cross plate 9 and the limit frame 6. Therefore, when hanging the silk thread 10, there is no need to remove the limiting device or manually reset it, which will not cause a significant impact on the hanging efficiency of the silk thread 10 and has a good use effect.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
