Description

Technical Field

[0001] This utility model relates to the field of wire stranding machine technology, specifically to a wire stranding machine with a tension adjustment structure. Background Technology

[0002] A wire stranding machine is a key electrical engineering device that spirally strands multiple single-strand metal conductors together according to certain rules to form a conductor with specific specifications and performance. Its core working process is as follows: multiple reels on the pay-off stand release single wires, which are initially gathered by a spool. Then, the main shaft rotates, driving the bow or tube to rotate, causing each single wire to spiral around the center line at a uniform speed, achieving tight and uniform stranding. During this process, the system must precisely control the pay-off tension in a closed loop and stably control the stranding pitch to ensure a consistent, round, and tight stranded conductor structure. This effectively reduces eddy current losses and skin effect during subsequent use, improving the cable's flexibility, stability, and electrical performance. It is widely used in the manufacture of power cables, communication cables, and various flexible conductors.

[0003] For example, the patent with authorization announcement number CN222580846U discloses a wire stranding machine with a tension adjustment structure. The support plate supports the wire feeding plate, preventing it from falling off during processing. The wire feeding plate can be disassembled and installed simply by turning the handle, which speeds up the stranding efficiency. The guide wheel rotates in the direction of wire feeding, thereby reducing friction. The machine can work continuously without wire jamming, thus increasing work efficiency and adjusting wire tension to ensure uniformity and stability of the wire. However, there are still areas for improvement.

[0004] The aforementioned patent relies on the friction of the guide wheel and the guide wire as the traction force for the movement of the guide wire. The coefficient of friction on the outer side of the guide wheel remains basically unchanged, but the smoothness of the outer side of different types of guide wires is inconsistent, that is, the coefficient of friction of the guide wheel and the guide wire is different. If it is too large, it will increase the wear of the guide wire, and if it is too small, it may cause slippage. If you want to select the corresponding guide wheel according to the coefficient of friction on the outer side of the guide wire, you need to remove and replace the guide wheel, which is cumbersome and affects production efficiency. Utility Model Content

[0006] A wire stranding machine with a tension adjustment structure includes a mounting frame, on the inner side of which two drive shafts are rotatably mounted, and the two drive shafts rotate in opposite directions. Multiple friction rings are fixedly installed on the outside of the drive shaft, and the friction coefficients of the outer sides of the friction rings increase sequentially. An electric push rod telescopic end is fixedly installed on the outside of the mounting bracket.

[0012] Preferably, an adjusting motor is fixedly installed on the top of the fixed frame, and a bidirectional lead screw is rotatably installed on the inner side of the fixed frame.

[0024] First embodiment: like Figure 1 , Figure 2 As shown, this utility model discloses a wire stranding machine with a tension adjustment structure, including a mounting frame 7. Two drive shafts 10 are rotatably mounted inside the mounting frame 7, and the two drive shafts 10 rotate in opposite directions. Figure 1 As shown, the drive shaft 10 at the upper position rotates counterclockwise, and the drive shaft 10 at the lower position rotates clockwise, both of which drive the guide to move in the same direction. Specifically, such as Figure 5 As shown, multiple friction rings 11 are fixedly installed on the outer side of the drive shaft 10. The friction coefficient of the outer side of the friction rings 11 increases sequentially. The operator can select the appropriate friction ring 11 according to the friction coefficient of the wire sheath to reduce the friction loss of the wire caused by excessive friction or the slippage caused by insufficient friction.

[0025] Specifically, such as Figure 2 As shown, an electric push rod 13 telescopic end is fixedly installed on the outside of the mounting bracket 7. The electric push rod 13 drives the drive shaft 10 and the friction ring 11 to move, which makes it convenient for the staff to adjust the position of the friction ring 11 so that the required friction ring 11 can work with the wire.

[0026] In this embodiment, a suitable friction ring 11 is selected based on the friction coefficient of the conductor surface. The operator starts the electric push rod 13, and the telescopic end of the electric push rod 13 extends or retracts, driving the required friction ring 11 to move and fit against the conductor, so that the subsequent traction force on the conductor is within the set range, and the traction work of the conductor can be carried out relatively smoothly.

[0027] Specifically, such as Figure 2 As shown, a drive gear 9 and a driven gear 12 are fixedly installed on the outer sides of the two drive shafts 10 respectively. The drive gear 9 and the driven gear 12 are meshed and installed so that the two drive shafts 10 rotate synchronously and in opposite directions. The output end of a drive motor 8 is fixedly installed at the end of one drive shaft 10. The drive motor 8 is fixedly installed on the outer side of the mounting bracket 7.

[0028] Second embodiment: The difference from the above embodiments is that, as Figure 1 , Figure 2 As shown, support frames 15 are slidably installed through both ends of the mounting frame 7, so that the mounting frame 7 can move stably. The base 1 is fixedly installed at the bottom of the two support frames 15.

[0029] Specifically, such as Figure 1 As shown, a stranding machine body 14 is installed on the top of the base 1 for winding the wire.

[0030] Specifically, such as Figure 1 As shown, a fixing frame 2 is fixedly installed on the top of the base 1, and two guide wheels 5 are installed on the inner side of the fixing frame 2, with a guide wire wound on the outer side.

[0031] Specifically, such as Figure 1 As shown, the outer wire of the upper-positioned guide wheel 5 enters the stranding machine body 14 along the top of the upper-positioned drive shaft 10, and the outer wire of the lower-positioned guide wheel 5 enters the stranding machine body 14 along the bottom of the lower-positioned drive shaft 10.

[0032] In this embodiment, the drive motor 8 starts, as follows: Figure 1 As shown, the drive shaft 10 and the drive gear 9 at the lower position rotate clockwise, thereby moving the wire at the bottom towards the stranding machine body 14. The drive gear 9 drives the drive shaft 10 at the upper position to rotate counterclockwise through the driven gear 12, thereby moving the wire at the top towards the stranding machine body 14.

[0033] Third embodiment: The difference from the above embodiments is that, as Figure 3As shown, an adjusting motor 3 is fixedly installed on the top of the fixed frame 2, and a bidirectional lead screw 4 is rotatably installed on the inner side of the fixed frame 2. The top of the bidirectional lead screw 4 is fixedly connected to the output end of the adjusting motor 3, and the end of the guide wheel 5 is movably connected to the bidirectional lead screw 4. The bidirectional lead screw 4 is used to drive the two guide wheels 5 to move closer or further away from each other, thereby adjusting the cooperation angle between the two guide wheels 5 and the drive shaft 10.

[0034] In this embodiment, the tension of the conductor is adjusted by the operator starting the adjusting motor 3, which drives the bidirectional lead screw 4 to rotate, thereby causing the two conductor wheels 5 to move closer or further apart, so that the height difference between the conductor on the outside of the conductor wheel 5 and the drive shaft 10 changes, and the tension on the conductor also changes accordingly. The operator can adjust it according to the material of the conductor and production requirements to meet more working conditions.

[0035] Specifically, such as Figure 4 As shown, a limiting rod 6 is fixedly installed on the inner side of the fixing frame 2. The limiting rod 6 slides through the end of the guide wheel 5 and limits the movement trajectory of the guide wheel 5.

[0036] Specific workflow: Based on the coefficient of friction of the conductor surface, a suitable friction ring 11 is selected. The operator starts the electric push rod 13, which extends or retracts, causing the required friction ring 11 to move and fit against the conductor. This ensures that the traction force on the conductor is within the set range, allowing the conductor traction work to proceed smoothly.

[0037] Drive motor 8 starts, such as Figure 1 As shown, the drive shaft 10 and the drive gear 9 at the lower position rotate clockwise, thereby moving the wire at the bottom towards the stranding machine body 14. The drive gear 9 drives the drive shaft 10 at the upper position to rotate counterclockwise through the driven gear 12, thereby moving the wire at the top towards the stranding machine body 14.

[0038] To adjust the tension of the conductor, the operator starts the adjusting motor 3, which drives the bidirectional lead screw 4 to rotate, thereby causing the two conductor wheels 5 to move closer or further apart. This changes the height difference between the conductor on the outer side of the conductor wheel 5 and the drive shaft 10, and the tension on the conductor changes accordingly. The operator adjusts the tension according to the material of the conductor and production requirements to meet more working conditions.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
