Background technology:
At present, the core spun yarn is used to produce elastic textile fabrics. The core spun yarn is made by covering the core spun yarn with cotton yarn. The core spun yarn is usually spun on a ring spinning frame. One of the components is called a guide wheel device, which guides the position of the core spun yarn. The guide wheel device is fixed on the frame of the ring spinning frame.
The traditional guide wheel device includes a fixed bracket and a guide wheel assembly arranged on both sides of the fixed bracket; the guide wheel component includes a bolt shaft and a guide wheel installed on the outer end of the bolt shaft, the other end of the bolt shaft is connected to the long nut of the fixed bracket and fixed with a hexagon nut. In the process of spinning, the position of the guide wheel needs to be adjusted because of the change of the position of the core. The traditional method is to use a tool (wrench) to loosen the hex nut, then adjust the position of the bolt shaft and the long nut, and then use a wrench to tighten the hex nut, so as to fix the position of the guide wire wheel.
The authorized publication number is cn206477080u, which discloses the guide wire wheel assembly, including the coupling and the guide wire wheel installed on the outer end of the coupling. The inner end of the coupling is provided with an external thread, and the inner end of the coupling is provided with a manual fixing nut. The manual fixing nut is made of metal materials, and the outer diameter of the manual fixing nut is more than 10 mm and not more than the outer diameter of the guide wire wheel, and the larger can be produced by screwing the fixing nut with fingers The manual fixing nut is close to the side wall of the long nut, so that the guide screw assembly can be tightly fixed on the long nut; the manual fixing nut can be loosened by fingers to make the manual fixing nut move away from the long nut on the coupling shaft, so as to adjust the relative distance between the guide screw and the long nut. As shown in Figure 7-9 of this document, the manual adjusting part is sleeved on the square section of the coupling, and the manual adjusting part and the coupling can rotate in the same axis. Since the coupling and the long nut are connected by thread, the distance between the guide wheel and the long nut can be adjusted by turning the manual adjusting part.
The manual adjusting part of the guide wheel assembly is located in the inner side of the guide wheel. Because the space inside the guide wheel is relatively narrow, and only the fingers can be screwed inside the guide wheel, there is certain inconvenience.
