[0002] A stranding machine is a device used for stranding cables. Its structure primarily consists of a drive shaft, a wing tension control mechanism, a conductor reel, and a storage reel.

The former, which cannot be adjusted, results in poor conductor stranding quality, while the latter, which is more expensive and creates conditions that hinder the operation of electronic components. Therefore, improvements to existing wing tension control mechanisms are urgently needed. Utility Model Content

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0027] One aspect of the present application provides an adaptive wing tension control mechanism, such as Figure 1 and Figure 2 As shown, one preferred embodiment includes a wheel body 141 and a plurality of tension control assemblies 142. The wheel body 141 is fixedly mounted on a transmission shaft (not shown) of the stranding machine. The tension control assemblies 142 are mounted at equal intervals along the circumferential direction on the side of the wheel body 141. The tension control assemblies 142 can tension the wire 220 released from a wire storage drum (not shown) mounted on the transmission shaft.

[0028] In this embodiment, there are many specific structures of the tension control component 142 that can achieve tensioning of the wire 220. For ease of understanding, one of the structures will be described in detail below. Figure 2 and Figure 4 As shown, the tension control assembly 142 includes a support frame 1421, a guide wheel 1422, a tension wheel 1423, and an elastic assembly 143. The support frame 1421 is fixedly mounted on the wheel body 141, and the guide wheel 1422 is rotatably mounted on the top of the support frame 1421. The tension wheel 1423 is rotatably mounted on a sliding seat 1426, which slides in a horizontally disposed chute 1420 on the support frame 1421. The wire 220 released from the wire storage reel can pass through the guide wheel 1422 and the tension wheel 1423 in sequence and extend to the twisting position. The elastic assembly 143 cooperates with the sliding seat 1426. When the tension of the wire 220 changes, the elastic assembly 143 can adaptively drive the tension wheel 1423 to move to maintain the tension of the wire 220.

[0029] It should be understood that in order to ensure that the tension wheel 1423 can stably tension the wire 220 , the guide wheel 1422 needs to deviate from the tension wheel 1423 in the horizontal direction.

[0030] In this embodiment, there are many specific structures of the elastic component 143. For the sake of easy understanding, one of the structures will be described in detail below. Figures 2 to 4As shown, elastic assembly 143 includes a pull cord 1431, a slide bar 1432, a first elastic member 1433, and a second elastic member 1434. Slide bar 1432 is mounted to support frame 1421 for flush sliding movement along the direction of movement of tension wheel 1423. First elastic member 1433 is mounted to slide bar 1432, providing an elastic sliding connection between slide bar 1432 and support frame 1421. Second elastic member 1434 has one end hinged to support frame 1421 and the other end connected to slide bar 1432 via pull cord 1431. The extension direction of second elastic member 1434 forms an angle of 90° to 150° with the axial direction of slide bar 1432. The pull rope 1431 can pull the tension wheel 1423 after passing through the traction wheel 1424 set on the sliding seat 1426, so that the tension wheel 1423 slides along the slide groove 1420 under the traction of the pull rope 1431 to achieve tensioning of the wire 220. The traction wheel 1424 can facilitate the sliding traction of the pull rope 1431.

[0031] It should be noted that the specific structures of the first elastic member 1433 and the second elastic member 1434 can be various, with common ones including shrapnel and spring. In this embodiment, a spring is preferably used as an example for detailed description. The first elastic member 1433 can be sleeved on the slide bar 1432, one end of the second elastic member 1434 is hinged to the support frame 1421 via a connected hinge seat 1436, and the other end of the second elastic member 1434 is connected to the pull rope 1431 via a connecting block 1435. The second elastic member 1434 can be arranged above or below the tension wheel 1423. If the second elastic member 1434 is arranged above the tension wheel 1423, the slide bar 1432 will be flush with the bottom of the traction wheel 1424; if the second elastic member 1434 is arranged below the tension wheel 1423, the slide bar 1432 will be flush with the top of the traction wheel 1424. For ease of understanding, this embodiment will be described in the following content by taking the example of the second elastic member 1434 being disposed below the tension wheel 1423 .

[0032] It is understandable that the hinge point between the second elastic member 1434 and the support frame 1421 can be marked as A, and the connection point between the first elastic member 1433 and the rear end of the slide bar 1432 can be marked as B. Then, during the movement of the tension wheel 1423, the deformation degree of the entire elastic component 143 can be represented by the change in the length of the line between points A and B. When the tension of the wire 220 changes, for example, the tension decreases; Figure 4 As shown, assuming that traction wheel 1424 moves rightward by a distance X, the change in the length of the line connecting points A and B will be less than X. This allows elastic component 143 of this embodiment to have a greater tension adaptation range compared to a traditional single spring structure. Furthermore, to ensure a stable force applied to tension wheel 1423, elastic components 143 can be installed at both ends of the rotational mounting position of tension wheel 1423.

[0033] In this embodiment, Figure 3 As shown, to ensure stable driving of the tension wheel 1423, both ends of the tension wheel 1423 along the axial direction can be rotatably mounted on corresponding sliding seats 1426. The sliding seats 1426 can be slidably mounted on the support frame 1421 corresponding to the slide grooves 1420 symmetrically arranged at the axial ends of the tension wheel 1423. Accordingly, the number of elastic components 143 is also two, and the two elastic components 143 are symmetrically arranged at the axial ends of the tension wheel 1423 and cooperate with the corresponding traction wheel 1424.

[0034] In this embodiment, Figure 5 As shown, the support frame 1421 is fixedly mounted with a clamping block 1425 at the same height as the tension wheel 1423. When the tension wheel 1423 moves to the extreme position, it can collide with the clamping block 1425, thereby clamping the slack wire 220 between the tension wheel 1423 and the clamping block 1425, thereby facilitating the subsequent rewiring of the wire storage reel. At the same time, it can also provide clamping protection against sudden breakage of the wire 220, preventing the wire 220 from flying out and causing damage.

[0035] It should be noted that when the wire storage reel completes winding, there will be no contact between the wire 220 and the wire storage reel. At this time, the wire 220 will be in a relaxed state, and the tension wheel 1423 can be driven by the elastic component 143 to slide away from the guide wheel 1422, or in other words, towards the clamping block 1425, until the tension wheel 1423 and the clamping block 1425 are against each other. This process is relatively fast, so the end of the wire 220 that maintains the pay-off trend can be quickly clamped to facilitate rewiring when the wire storage reel is subsequently replaced. At the same time, when the wire 220 suddenly breaks, the pressure of the wire 220 on the tension wheel 1423 will suddenly disappear. At this time, the tension wheel 1423 can also quickly approach the clamping block 1425 and clamp the broken wire 220 under the elastic force of the elastic component 143.

Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
