[0002] Tensioners are widely used in the motor industry and coil winding processes. The winding tension has a great impact on the appearance and performance of the coil products, and directly affects the quality of the finished product. Therefore, the winding machine needs to be equipped with a tensioner, which is the core component of the coil product to generate adjustable tension during winding, so that the enameled wire has a suitable tension during winding. After searching, a winding machine servo tensioner (publication number: CN216863264U) is now disclosed. This patent can only adjust the tension of a single wire in winding production, and cannot adjust the tension in real time during use. For this reason, we proposed a dual-control tensioner. By setting a gravity sensor and a brake, the control panel adjusts and controls the tension and other parameters of the tensioners on both sides respectively, thereby realizing simultaneous winding with the same or different parameters.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-4The utility model provides a technical solution for a double-control tensioner: a double-control tensioner, comprising a frame 1, a tension adjustment component 2, a power wheel 3, an upper anti-jump device 4, a lower anti-jump device 5, a tension sensing wheel 6, a through slot 7, a control panel 8 and a fixing seat 9. Specifically, multiple groups of upper anti-jump devices 4 and lower anti-jump devices 5 can prevent wires from falling off, and each group of wires sequentially bypasses the lower anti-jump device 5, the power wheel 3, the upper anti-jump device 4, the mobile anti-jump device 23 on the tension adjustment component 2, the upper anti-jump device 4, the tension sensing wheel 6 and the upper anti-jump device 4. The device adopts a double-station tensioning structure, and two groups of wires are tensioned respectively by two groups of tension adjustment components 2 during the winding process;

[0039] Each set of power wheels 3 and frame 1 are installed with brakes 31 (equivalent to a damper). When the wire moves, the brakes 31 apply resistance to the power wheels 3 according to production requirements, so as to adjust the tension on the wire. Each set of tension sensing wheels 6 and frame 1 are installed with gravity sensors 61. When the wire moves, the tension sensing wheels 6 detect the tension on the wire through the gravity sensor 61, and transmit the detection data to the control panel. The dual-control tensioner is equivalent to two tensioners combined together, sharing a control system. The tension and other parameters of the tensioners on both sides can be adjusted and controlled through the control panel 8, so as to achieve simultaneous winding with the same or different parameters. The tension on the wire during winding is controlled by the brake 31, the gravity sensor 61 and the program set in the control circuit.

[0040] The tension adjustment assembly 2 includes a guide rail 21, a slide 22, a movable anti-jump device 23, a mounting plate 24, a fixing block 25, an adjusting nut 26, a screw 27, a locking bolt 28 and a spring 29. Specifically, when the wire passes around the lower part of the movable anti-jump device 23 and the wire passing through the movable anti-jump device 23 is tight, the wire drives the movable anti-jump device 23 and the slide 22 to move upward along the guide rail 21 and stretch the spring 29. When the wire passing through the movable anti-jump device 23 is loose, the spring 29 contracts and pulls the movable anti-jump device 23 and the slide 22 to move downward along the guide rail 21, thereby tensioning the wire; and loosening the locking bolt 28, rotating the adjusting nut 26 to move the screw 27 upward or downward, thereby adjusting the lower starting end position of the spring 29. After the adjustment is completed, tighten the locking bolt 28 to lock the adjusting nut 26. This structure can adjust and switch the tension according to needs.

[0041] In actual use, the dual-control tensioner passes two wires around the lower anti-jump device 5, the power wheel 3, the upper anti-jump device 4, the mobile anti-jump device 23 on the tension adjustment component 2, the upper anti-jump device 4, the tension sensing wheel 6 and the upper anti-jump device 4;

[0042] During the winding process, two groups of gravity sensors 61 are used to enable two groups of tension sensing wheels 6 to detect the tension on the wires on both sides respectively, and transmit the detection data to the control panel 8. The control panel 8 controls two groups of brakes 31 to apply resistance to the two groups of power wheels 3 respectively, thereby adjusting the tension on the wires on both sides, and then the control panel 8 adjusts and controls the tensioners on both sides respectively to adjust the tension size and other parameters, thereby achieving simultaneous winding with the same or different parameters.

[0043] When the wire passing through the movable anti-jump device 23 is tight, the wire drives the movable anti-jump device 23 and the slide 22 to move upward along the guide rail 21 and stretch the spring 29. When the wire passing through the movable anti-jump device 23 is loose, the spring 29 contracts and pulls the movable anti-jump device 23 and the slide 22 to move downward along the guide rail 21, thereby tensioning the wire so that the wire is always in a tensioned state.
