[0001] This utility model relates to the field of wire feeding frame technology, specifically a wire feeding frame for constant tension winding. Background Technology

[0002] A winding machine is a device that can wind a wire into a specific workpiece. It is widely used. In the process of power construction, it is usually necessary to use a winding machine to wind or unwind cables. During the unwinding process, a corresponding unwinding frame is required.

[0003] Chinese patent application CN216889420U discloses a wire feeding frame for winding, including a tension adjustment mechanism, a transmission mechanism, a stepping frame, and a base. The transmission mechanism is located above the stepping frame and has multiple sets. The adjustment mechanism is located on one side of the stepping frame. Tension is adjusted by rotating a handle to drive an adjustment block, causing two clamping plates to clamp a brake disc. The brake disc is fixed to one end of the central shaft of the transmission mechanism, and a wire spool is detachably mounted on the other end of the shaft. The wire spool is fixedly connected to the shaft via a side plate. The shaft is movably connected to the stepping frame via a bearing seat. Multiple tension adjustment mechanisms are connected by a synchronous belt to achieve synchronous tension adjustment. The length of the columns in the stepping frame is adjustable, thereby adjusting the height of the stepping frame. The wire feeding frame is fixed to the ground via the base and ground anchor bolts. This utility model can control winding tension, and its overall structure is flexible and adjustable. It utilizes design concepts such as frictional resistance, three-point alignment, and sequential stepping to ensure the safety of the wire feeding frame and guarantee the winding quality of the coil.

[0004] However, the above-disclosed wire feeding frames have limited freedom of movement and cannot adjust the angle of the wire feeding frame according to actual needs, lacking a quick adjustment structure. Summary of the Invention

[0019] The technical solution of this utility model will now be clearly and completely described with reference to Figures 1 to 4. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides an improved constant tension winding pay-off frame, as shown in Figures 1-4. It includes a base 1, with a first swing frame 5 and a second swing frame 7 mounted on the top of the base 1. The first and second swing frames 5 and 7 have freely adjustable engagement rods 15 inside, and a top plate 17 is mounted on the top of the engagement rods 15. A vertical rod 18 is fixedly mounted on the top of the top plate 17, and a T-slot 19 is also provided on the top of the top plate 17. A take-up drum 20 is movably mounted on the top of the top plate 17, and a T-shaped seat 21 that mates with the T-slot 19 is provided at the bottom of the take-up drum 20. A spring 22 is connected to the inner wall of the take-up drum 20, and the take-up drum 20 is connected to the vertical rod 18 through the spring 22. Multiple lifting cylinders 2 are mounted on the bottom of the base 1, and a conical seat 3 is provided at the output end of each lifting cylinder 2.

[0021] The swing angles of the first swing frame 5 and the second swing frame 7 can be adjusted by swing motor 6 and swing motor 8. Simultaneously, the position and angle of the take-up drum 20 are rapidly adjusted under the action of the swing ball 12 and the engaging rod 15. When the take-up drum 20 unwinds the wire, the mainspring 22 tightens. When winding is required, the take-up drum 20 automatically winds the wire under the action of the mainspring 22. This design improves the freedom of movement and winding effect of the constant tension winding unwinding frame.

[0022] Referring to Figures 2-4, the top of the base 1 is provided with multiple sets of adjustment seats 4. The first swing frame 5 and the second swing frame 7 are movably installed on the top of the adjustment seats 4 and are perpendicular to each other. The first swing frame 5 has a swing cavity 9 inside, and the second swing frame 7 has a swing cavity 10 inside. The outer wall of the adjustment seat 4 is equipped with a swing motor 6 that drives the first swing frame 5 and a swing motor 8 that drives the second swing frame 7.

[0023] In this embodiment: when the first swing motor 6 drives the first swing frame 5 to swing to the left, the engagement rod 15 and the take-up drum 20 swing to the left accordingly. When the second swing motor 8 drives the second swing frame 7 to swing to the left, the engagement rod 15 and the take-up drum 20 swing to the left accordingly.

[0024] Referring to Figures 2-4, a moving slider 16 is provided at the bottom of the engaging rod 15, and a fixed slider 11 is provided at the top of the base 1. A swing ball 12 is movably arranged between the moving slider 16 and the fixed slider 11. A first slide 13 that cooperates with the fixed slider 11 is opened at the bottom of the swing ball 12, and a second slide 14 that cooperates with the moving slider 16 is opened at the top of the swing ball 12.

[0025] In this embodiment: During the winding operation, the swing ball 12 can drive the winding drum 20 to swing in tandem. When the engaging rod 15 and the winding drum 20 swing with the second swing frame 7, the moving slider 16 is stationary relative to the second slide rail 14, and the fixed slider 11 slides back and forth along the first slide rail 13. When the engaging rod 15 and the winding drum 20 swing with the first swing frame 5, the fixed slider 11 is stationary relative to the first slide rail 13, and the moving slider 16 slides back and forth along the second slide rail 14.

[0026] Referring to Figure 3, a sensor 23 is also installed at the bottom of the top plate 17.

[0027] In this embodiment: when the device is placed on an uneven ground, the sensor 23 and the lifting cylinder 2 work together to keep the base 1 in a horizontal state.
