[0002] The function of the godet on the spinning machine is to guide and transport the core yarn stably and provide a certain tension force; the rotation power of the godet comes from the traction force of the core yarn, and the friction between the core yarn and the godet drives the godet to rotate. By monitoring the rotation of the godet, the state of the core yarn can be judged, which is mainly used to judge whether the core yarn is broken; When double-core yarn is used to make wound double-core core-spun yarn, in order to reduce the redundancy of the structure, the originally independently set wire guide wheel structure is merged into the rear end area of ​​the guide wheel frame, avoiding the situation where the original wire guide wheel structure needs to be lifted by a roller when being cut, thereby reducing the redundancy of the structure; when the new double wire guide wheel is formed, the original unit detection cannot realize double-wheel detection during detection. Therefore, a double-core yarn double-wheel detection wire guide structure is needed to realize this detection function. Summary of the invention

[0020] The double guide wheel unit includes an inner guide wheel unit 31 and an outer guide wheel unit 32, and a cavity for accommodating a side surface of the inner guide wheel unit 31 is opened on the side surface of the outer guide wheel unit 32 adjacent to the inner guide wheel unit 31, and the outer side surface of the inner guide wheel unit 31 is embedded in the cavity to prevent yarn or flying catkins from entering the rotating position of the double guide wheel unit.

[0021] A transparent dust cover 11 is buckled on the inner side surface of the inner guide wheel unit 31 close to the side of the guide wheel frame 1, and the transparent dust cover 11 is installed on the connecting part 2 on the guide wheel frame 1; a dust cover or sealing device is arranged on the outer side surface of the outer guide wheel unit 32.

[0022] In the production of double-core yarn, the combination of guide wheel units with the serial number 12 in Table 2 is used; that is, a single guide wheel unit on the front side and a double guide wheel unit on the rear side are used on the guide wheel frame 1; the double-core yarn is guided on one side of the guide wheel frame 1; or the combination of guide wheels with the serial number 20 in Table 2 is used; that is, a single guide wheel unit on the front side and a double guide wheel unit on the rear side are used on the guide wheel frame 1, so as to guide the double-core yarn on both sides of the guide wheel frame 1; like Figure 3 As shown: the two core wires in the double core wire pass through the double wire guide wheel unit at the rear end of the guide wheel frame 1 respectively, and the friction force of the two core wires drives the double wire guide wheel unit to rotate; then pass through the single wire guide wheel unit at the front end of the guide wheel frame 1, and are twisted with the wrapping wire on the side, and the wire guide wheel stop detection box 4 detects the double wire guide wheel unit; if it is detected that any wire guide wheel unit on the double wire guide wheel unit stops rotating, the feeding of the core wire and the wrapping wire can be controlled to stop; In the original production process of double-core wire, a single wire guide wheel unit is set on the front and rear ends of the guide wheel frame, one of the core wires does not pass through the single wire guide wheel unit on the guide wheel frame, and the other core wire passes through the single wire guide wheel unit at the front and rear ends of the guide wheel frame respectively; in this way, it is difficult to detect the disconnection of the core wire of the single wire guide wheel unit that does not pass through the guide wheel frame.
