Description

Technical Field

[0001] This utility model relates to the field of wire and cable processing technology, and in particular to a strand tension adjustment device for wire and cable processing. Background Technology

[0002] In the manufacturing process of wires and cables, stranding is the core process of spirally twisting multiple metal conductors or insulated cores into a cable core at a specific pitch. The accuracy and stability of tension control directly determine the electrical performance, mechanical strength, and appearance quality of the stranded cable. If the tension of a single wire is uneven or fluctuates too much, it will lead to a loose stranding structure, inconsistent pitch, and even cause problems such as scratches and breaks on the wire surface, seriously affecting the product qualification rate.

[0003] The current wire tension adjustment devices commonly used in the industry suffer from the following technical bottlenecks:

[0004] Response lag and coarse adjustment: Traditional mechanical counterweights or spring tension mechanisms rely on the principle of physical balance, requiring manual intervention for adjustment and failing to achieve dynamic real-time response. When faced with different wire diameters or speed changes, tension adjustment exhibits significant lag and limited adjustment accuracy, making it difficult to meet the process requirements of high-specification cables.

[0005] Lack of stepless fine-tuning capability: Mechanical structures using graded gears or limit pins can only achieve discrete gear adjustments, and cannot continuously fine-tune the tension according to process requirements. Especially when stranding ultra-fine diameter wires (e.g., <0.1mm) or high-precision signal cables, tension fluctuations can easily lead to pitch drift. Therefore, a stranded wire tension adjustment device for wire and cable processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to provide a strand tension adjustment device for wire and cable processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0008] To achieve the above objectives, one embodiment of the present invention provides a strand tension adjustment device for wire and cable processing, comprising a base, a frame, a geared motor, and guide wheels. The top of the base is fixedly connected to the frame, and the back of the frame is fixedly connected to the geared motor.

[0009] The front of the frame is movably connected to two guide wheels, and the output end of the reduction motor is linked to the guide wheels.

[0010] The top of the base is fixedly connected to several joints, and a rotating frame is movably connected above one of the joints;

[0011] An adjusting wheel is movably connected to the top of the inner side of the rotating frame, and an electric cylinder is movably connected above the other connector;

[0012] A contact is fixedly connected to one side of the rotating frame, and the contact is movably connected to the end of the electric cylinder output terminal.

[0013] A tension spring is fixedly connected between the contact point and the base.

[0014] Preferably, of any of the above solutions, the base is welded to the frame, and the geared motor is installed horizontally.

[0015] The above technical solution is adopted: This device is specially used for cable and wire processing. Multiple cables are twisted together after tension adjustment on this device.

[0016] The basic working principle of this device is as follows: When the geared motor is working, there is a sprocket at the end of the geared motor, which drives the chain to rotate, thereby driving a guide wheel to rotate. When this guide wheel rotates, it drives another guide wheel to rotate through the chain and sprocket, thereby conveying multiple cables. The multiple cables pass through the frame and then go around the bottom of the guide wheel. When the output end of the electric cylinder pushes out, the rotating frame rises and the cable tension decreases. When the output end of the electric cylinder retracts, the rotating frame descends and the cable tension increases. At this time, the tension spring is pressed down.

[0017] Precise tension control and faster electric cylinder response enable stepless tension adjustment. When the electric cylinder retracts, the tension increases, and the tension spring depresses, enhancing system reliability and providing backup tension (failure prevention mechanism) in case of electric actuator failure. This also makes the movement of the rotating frame smoother and more stable, with more stable tension adjustment. The load on the electric cylinder remains constant during extension and retraction, eliminating jerking and vibration. Actual measurements show reduced amplitude and smaller cable tension fluctuations.

[0018] Preferably, the linkage between the geared motor and the guide wheel is as follows: a sprocket is fixedly connected to the end of the guide wheel, a sprocket is fixedly connected to the output end of the geared motor, and the sprockets are linked together by a chain.

[0019] The above technical solution comprises: a basic frame, a base (horizontal mounting platform) with a welded frame on top, and a geared motor (horizontally fixed to the back of the frame, with a sprocket mounted at the output end).

[0020] Cable conveying unit: Two guide wheels, movably connected to the front of the frame. A sprocket is fixed to the end of each guide wheel, and the two sprockets are linked by a chain. The sprocket of the geared motor drives the first guide wheel via the chain, which in turn drives the second guide wheel, achieving synchronous conveying of multiple cables.

[0021] Tension adjustment unit with two connectors: fixed to the top of the base. Rotating frame: U-shaped structure, movably connected to the upper end of the first connector via a pin, initially parallel to the frame body. Adjusting wheel: movably connected to the inner top of the rotating frame, with guide grooves on its outer surface.

[0022] Electric cylinder: It is movably connected to the upper end of the second connector, and the output end is movably connected to the contact (the contact is welded to the side of the rotating frame).

[0023] Tension spring: Both ends are fixed to the contact point and the base respectively, providing continuous downward pressure.

[0024] Preferably, in any of the above solutions, the rotating frame is U-shaped and rotatable.

[0025] Preferably, in any of the above schemes, the outer surfaces of the adjusting wheel and the guide wheel are provided with a plurality of guide grooves, and the rotating frame is initially parallel to the frame body.

[0026] Preferably, in any of the above schemes, when the output end of the electric cylinder extends, the rotating frame rises; when the output end of the electric cylinder retracts, the rotating frame descends.

[0027] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0028] This wire and cable processing strand tension adjustment device features precise tension control, a faster electric cylinder response, and stepless tension adjustment. When the electric cylinder retracts, the tension increases, and the tension spring depresses, enhancing system reliability and providing backup tension (fail-proof mechanism) in case of electric actuator failure. It also ensures smoother and more stable movement of the rotating frame, making tension adjustment more stable. The device maintains a constant load on the electric cylinder during extension and retraction, eliminating jerking and vibration. Actual measurements show reduced amplitude and smaller cable tension fluctuations.

[0038] like Figure 1-4 As shown, this wire and cable processing strand tension adjustment device includes a base 1, a frame 2, a reduction motor 3, and a guide wheel 4. The frame 2 is fixedly connected to the top of the base 1, and the reduction motor 3 is fixedly connected to the back of the frame 2.

[0039] The front of the frame 2 is movably connected to two guide wheels 4, and the output end of the reduction motor 3 is linked to the guide wheels 4;

[0040] Several connectors 5 are fixedly connected to the top of the base 1, and a rotating frame 6 is movably connected above one connector 5;

[0041] An adjusting wheel 7 is movably connected to the top of the inner side of the rotating frame 6, and an electric cylinder 8 is movably connected above the other connector 5;

[0042] A contact 9 is fixedly connected to one side of the rotating frame 6, and the contact 9 is movably connected to the end of the output terminal of the electric cylinder 8.

[0043] A tension spring 10 is fixedly connected between contact 9 and base 1.

[0044] Example 1: The base 1 is welded to the frame 2, and the geared motor 3 is horizontally installed. The linkage between the geared motor 3 and the guide wheel 4 is as follows: a sprocket is fixedly connected to the end of the guide wheel 4, and a sprocket is fixedly connected to the output end of the geared motor 3; the sprockets are linked by a chain. The rotating frame 6 is U-shaped and rotatable. Several guide grooves are provided on the outer surfaces of the adjusting wheel 7 and the guide wheel 4. Initially, the rotating frame 6 is parallel to the frame 2. When the output end of the electric cylinder 8 extends, the rotating frame 6 rises; when the output end of the electric cylinder 8 retracts, the rotating frame 6 descends.

[0045] Example 2: This device is specifically designed for cable and wire processing. Multiple cables are twisted together after tension adjustment on this device.

[0046] Device components: basic frame, base 1: horizontal mounting platform, top welded frame 2. Gear motor 3: horizontally fixed to the back of frame 2, with a sprocket mounted at the output end.

[0047] Cable conveying unit: Two guide wheels 4 are movably connected to the front of the frame 2. A sprocket is fixed to the end of each guide wheel 4, and the two sprockets are linked by a chain. The sprocket of the geared motor 3 drives the first guide wheel 4 through the chain, which in turn links the second guide wheel 4, to achieve synchronous conveying of multiple cables.

[0048] Tension adjustment unit, two connectors 5: fixed to the top of base 1. Rotating frame 6: U-shaped structure, movably connected to the upper end of the first connector 5 via a pin, initially parallel to frame 2. Adjusting wheel 7: movably connected to the inner top of rotating frame 6, with guide grooves on its outer surface.

[0049] Electric cylinder 8: It is movably connected to the upper end of the second connector 5, and the output end is movably connected to the contact 9 (the contact 9 is welded to the side of the rotating frame 6).

[0050] Tension spring 10: Both ends are fixed to the contact point 9 and the base 1 respectively, providing continuous downward pressure.

[0051] The working principle of this utility model is as follows:

[0052] When the geared motor 3 is working, the end of the geared motor 3 has a sprocket, which drives the chain to rotate, thereby driving a guide wheel 4 to rotate. When this guide wheel 4 rotates, it drives another guide wheel 4 to rotate through the chain and sprocket, thereby conveying multiple cables. The multiple cables pass through the frame 2 and then go around the bottom of the guide wheel 4. When the output end of the electric cylinder 8 pushes out, the rotating frame 6 is raised and the cable tension is reduced. When the output end of the electric cylinder 8 is retracted, the rotating frame 6 is lowered and the cable tension is increased. At this time, the tension spring 10 is pressed down.

[0053] Cable path: Multiple cables pass through frame 2 → around the two guide wheels 4 → exit below the adjusting wheel 7 ( Figure 1 (Arrow direction).

[0054] Tension adjustment mechanism: Decrease tension: The output end of electric cylinder 8 pushes out → pushes contact 9 upward → rotating frame 6 rotates around connector 5 and lifts → adjusting wheel 7 rises → cable path wrap angle decreases → tension decreases. Increase tension: The output end of electric cylinder 8 retracts → tension spring 10 pulls down contact 9 → rotating frame 6 descends → adjusting wheel 7 presses down → cable path wrap angle increases → tension increases.

[0055] Linkage: Gear motor 3 → chain → guide wheel 4 sprocket → double guide wheels 4 rotate synchronously → cable is conveyed at a constant speed. Tension is controlled in real time by the stroke of electric cylinder 8.

[0056] Compared with the prior art, the present invention has the following advantages:

[0057] This wire and cable processing strand tension adjustment device features precise tension control, a faster response from electric cylinder 8, and stepless tension adjustment. When electric cylinder 8 retracts, the tension increases, and tension spring 10 depresses, enhancing system reliability and providing backup tension (failure prevention mechanism) in case of electric actuator failure. It also ensures smoother and more stable movement of the rotating frame 6, making tension adjustment more stable. The device maintains a constant load on electric cylinder 8 during extension and retraction, eliminating jerking and vibration. Actual measurements show reduced amplitude and smaller cable tension fluctuations.
