[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-2 5-7 show a detection device for copper wire twisting, comprising a threading wheel 1 and a twisting wheel 4 and a discharging wheel 5 which are arranged in parallel with each other, a plurality of threading holes 3 are provided at the inner end of the threading wheel 1, copper single wires 2 are passed through the inner ends of the plurality of threading holes 3, the plurality of copper single wires 2 all pass through the twisting wheel 4, and the plurality of copper single wires 2 form a finished copper wire 6, and slide grooves 7 are provided on the upper and lower sides of the ends where the twisting wheel 4 and the discharging wheel 5 are close to each other, a detection disc 8 is slidably connected between the two corresponding slide grooves 7, and a pressure airbag 10 is fixedly connected to the inner wall of the detection disc 8.

[0028] Figure 1-25-7 show that a protective cover 14 is fixedly connected to one end of the stranding wheel 4 and the discharging wheel 5 which are close to each other, and the finished copper wire 6 cooperates with the two pressure airbags 10. Both pressure airbags 10 are externally connected to an air pressure detector, and both air pressure detectors are externally connected to a control terminal. A first contact sensor 9 is installed on the inner side of the slide slot 7 at the lower end, and the first contact sensor 9 is in contact with the detection disc 8, and the first contact sensor 9 is connected to the control terminal.

[0029] Figure 1-2 5-7 show that in this scheme, multiple copper single wires 2 are passed through the threading holes 3, and twisted in the stranding wheel 4, and the finished copper wire 6 is wound and transported through the winding equipment connected to the discharge wheel 5. During the discharge process of the finished copper wire 6, it is necessary to reasonably monitor the thickness range of the finished copper wire 6. Therefore, a protective cover 14 is arranged between the stranding wheel 4 and the discharge wheel 5 in the discharge area of ​​the finished copper wire 6. On the one hand, it is used for protection. On the other hand, a pair of detection discs 8 arranged in the protective cover 14 can be used to monitor the thickness range of the finished copper wire 6 when it is discharged, so as to ensure the qualified rate of the finished copper wire 6. Specifically, two detection discs 8 are respectively arranged on both sides of the finished copper wire 6, and the detection discs 8 are used to limit the position through the slide 7. When the finished copper wire 6 is within the normal and reasonable range of thickness, the finished copper wire 6 passes through the pressure airbag 10 in the detection disc 8, and the pressure gas will not be caused. The pressure bag 10 produces a large degree of air pressure change, and when the finished copper wire 6 is in an unreasonable range of too thick thickness, the finished copper wire 6 passes through the pressure bag 10 in the detection disc 8, which will cause the pressure bag 10 to produce a large degree of air pressure change, and the air pressure detector connected to the detection disc 8 receives the abnormal signal and reports it to the control terminal through the microprocessor to issue an abnormal alarm of too thick to the staff, and when the finished copper wire 6 is in an unreasonable range of too thin thickness, the finished copper wire 6 passes through the pressure bag 10 in the detection disc 8, which will cause a gap between the two detection discs 8 and the finished copper wire 6, causing the detection disc 8 to sag outside the slide 7, causing the detection disc 8 to contact with the first contact sensor 9, and also sending an abnormal alarm of too thin to the staff through the control terminal, and the air pressure detector and the microprocessor and the control terminal and the contact sensor are all prior art, which will not be repeated in this technical solution.

[0030] The second implementation method:

[0031] Figure 3-4A detection device for copper wire twisting is shown. When the copper single wire 2 passes through the threading hole 3, a flexible liner 12 can be set on the threading hole 3 and the side of the annular rear plate 11 close to the copper single wire 2 to reduce the friction between the two. At the same time, the annular rear plate 11 is hinged at the side end of the threading hole 3. When the copper single wire 2 passes through normally, the annular rear plate 11 does not contact the threading hole 3. When the copper single wire 2 is accidentally disconnected, the annular rear plate 11 can sag naturally, so that the annular rear plate 11 contacts the second contact sensor 13 outside the threading hole 3. After the second contact sensor 13 is subjected to the impact force, it also sends an abnormal signal to the control terminal, so that the staff can come to deal with it in time, thereby increasing the disconnection detection functionality of the copper single wire 2.

[0032] Figure 3-4 It is shown that the upper side of the rear end of the threading hole 3 is hingedly connected to an annular rear plate 11, and the lower side of one end of the threading hole 3 close to the annular rear plate 11 is fixedly connected to a second contact sensor 13, the second contact sensor 13 is in contact with the annular rear plate 11, and the ends of the threading hole 3 and the annular rear plate 11 that are in contact with the copper single wire 2 are fixedly connected with a flexible inner liner 12, and the second contact sensor 13 is connected to the control terminal.

[0033] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
