[0002] Litz wire is a multi-strand wire made of various single enameled wires that are bundled in accordance with the requirements of the stranding machine (also known as the wire bundling machine). Litz wire is produced in various specifications on the diameter of the conductor. The current wire stranding machine is a traditional wire stranding equipment, which does not have matching functions such as bare wire detection and broken wire detection, nor does it have the ability to warn and shut down due to defects caused by these factors. As a result, after the stranding is completed, some of the wire bundles will be mixed with bare wires (there is no paint film layer on the surface of the wire bundle) and broken wires (the wire bundle is disconnected in the middle and not connected together), causing poor functionality of the entire wire bundle.

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0022] As Figures 1 to 5 shown, in this embodiment, a wire breakage and bare wire detection device for a stranding machine includes a frame 1, a first detection roller shaft 2, a second detection roller shaft 3, a third detection roller shaft 4 and a support sheet metal 5. The first detection roller shaft 2 and the second detection roller shaft 3 are respectively located at the front end and the rear end of the frame 1. The ends of the first detection roller shaft 2 and the second detection roller shaft 3 are both connected with negative electrodes. The third detection roller shaft 4 is located between the first detection roller shaft 2 and the second detection roller shaft 3. The end of the third detection roller shaft 4 is connected with a positive electrode. The support sheet metal 5 is fixed in the middle of the frame 1. A plurality of photoelectric switches 6 are horizontally arranged on the support sheet metal 5. The photoelectric switches 6 are installed vertically downward. A plurality of limit grooves 7 are arranged on the third detection roller shaft 4. The limit grooves 7 surround the outside of the third detection roller shaft 4.

[0023] The single-strand enameled wire 24 enters the wire breakage and bare wire detection device of the stranding machine through the wire release of the wire release frame, and successively passes through the first detection roller shaft 2, the third detection roller shaft 4 and the second detection roller shaft 3. Since the first detection roller shaft 2 and the second detection roller shaft 3 are connected with negative electrodes, and the third detection roller shaft 4 is connected with a positive electrode (a carbon brush is arranged on the third detection roller shaft 4, DC 24V), when the paint film layer on the outer layer of the enameled wire 24 does not exist, the insulation performance will be lost, and the positive electrode and the negative electrode will be conducted under the exposed conductor of the enameled wire 24, and the host will pause working and requires manual intervention to start.

[0024] When the enameled wire 24 passes through the third detection roller shaft 4 between the first detection roller shaft 2 and the second detection roller shaft 3, there is an optoelectronic switch 6 above the third detection roller shaft 4. Each optoelectronic switch 6 is independently connected to the internal control box of the frame 1. When the enameled wire 24 continuously contacts the optoelectronic switch 6, the optoelectronic switch 6 is in a normally closed state. If the enameled wire 24 is broken or other obstacles are sensed by the optoelectronic switch 6, the optoelectronic switch 6 will enter a normally open state. At this time, the frame 1 cannot be started and requires manual intervention to start.

[0025] Through the above two detections, the bare wire and broken wire of the enameled wire 24 are detected respectively. The functions of the two detections with different performances are concentrated on the same device, enhancing the use value.

[0026] The support sheet metal 5 is an L-shaped bending structure. There are several wire holes 8 horizontally arranged on the vertical part of the support sheet metal 5. The signal wire of the optoelectronic switch 6 passes through the wire holes 8. There is an installation groove 9 on the horizontal part of the support sheet metal 5. The optoelectronic switch 6 is installed in the installation groove 9.

[0027] During the production process, the flat support sheet metal 5 is bent into an L shape and installed on the frame 1. The optoelectronic switch 6 is installed in the installation groove 9 of the support sheet metal 5 along the vertical direction, and the horizontal fixed position can be adjusted according to the passing position of the enameled wire 24. In order to prevent the signal wire of the optoelectronic switch 6 from being randomly wound, the signal wire passing through the wire holes 8 can be in good order.

[0028] The optoelectronic switch 6 is provided with an upper mounting pad 10 and a lower mounting pad 11. The upper mounting pad 10 is located on the upper surface of the installation groove 9, and the lower mounting pad 11 is located on the lower surface of the installation groove 9. The upper mounting pad 10 and the lower mounting pad 11 are both threadedly connected to the optoelectronic switch 6.

[0029] The optoelectronic switch 6 is locked in the appropriate position of the installation groove 9 through the upper mounting pad 10 and the lower mounting pad 11, and will not shift or tilt.

[0030] Both ends of the first detection roller shaft 2, both ends of the second detection roller shaft 3, and both ends of the third detection roller shaft 4 are connected with bearing seats 12, and the bearing seats 12 are fixed on the edge of the frame 1.

[0031] Specifically, a first driven wheel is provided at one end of the first detection roller 2, a second driven wheel is provided at one end of the second detection roller 3, a third driven wheel 13 is provided at one end of the third detection roller 4, a drive motor 14 is installed inside the frame 1, a driving end of the drive motor 14 is connected to a driving wheel 15, the driving wheel 15 is located on the outside of the frame 1, the driving wheel 15 is connected to the third driven wheel 13 by a chain 16, and the first driven wheel, the second driven wheel and the third driven wheel 13 are connected by a chain 16.

[0032] The first detection roller 2 , the second detection roller 3 and the third detection roller 4 are driven to rotate by the driving motor 14 , and the three axes operate synchronously, thereby ensuring the uniform speed conveyance of the enameled wire 24 .

[0033] A ventilation position 17 is disposed on one side of the frame 1 , and a control panel 18 is disposed on the other side of the frame 1 . A start button 19 and a speed regulating dial 20 are disposed on the control panel 18 .

[0034] The control panel 18 on one side is manually used to start and adjust the speed to meet the needs of working winding, and the heat generated by the internal components at the other side is taken out of the rack 1 through the ventilation position 17 to cool it down.

[0035] The frame 1 is provided with a locking hole 21 and a locking screw. An adjusting frame 22 is connected below the third detection roller 4. The adjusting frame 22 is provided with an adjusting hole 23 along the vertical direction. The locking screw passes through the adjusting hole 23 and is locked in the locking hole 21.

[0036] In order to maintain the tension of the enameled wire 24, the adjustment frame 22 can be adjusted up and down through the adjustment hole 23, and after being locked by the locking screw, the enameled wire 24 can be kept in a taut state.

[0037] All the single enameled wires 24 of all the bundles can be free of bare wires; the enameled wires 24 twisted out of each shaft can be produced according to the number of strands set by the process, without too many strands; for bundles with excellent insulation performance, the resistance of the twisted wires is close, and the performance of the enameled wires 24 is stable; for bundles with a number of strands that meet the process requirements, the electrical properties of the twisted wires are stable, and the performance of the enameled wires 24 is stable.

[0038] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present invention.
