Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, and in particular to a winding tension adjustment mechanism for a continuous production line of tin-plated copper wire. Background Technology

[0002] Tinned copper wire, as an important raw material in the electronics industry, needs to be neatly wound into spools by winding equipment at the end of the production process. The quality of winding, such as whether the spool is flat and whether the wire is damaged, directly determines the final quality of the product and the convenience of subsequent processing.

[0003] Precise control of wire tension is crucial for ensuring winding quality during the winding process. Excessive tension will cause the soft tin-plated copper wire to be stretched excessively, altering its original physical properties and even damaging the tin plating layer. Insufficient tension, on the other hand, will result in loose winding, uneven coils, and problems such as tangled wires and wire compression, affecting subsequent unwinding.

[0004] To achieve tension control, existing take-up equipment typically employs tension adjustment mechanisms. However, on continuous production lines, the take-up speed is not constant, especially during start-up, stop, or speed switching phases, where the wire tension experiences instantaneous fluctuations. Many traditional tension adjustment mechanisms, such as those using simple friction damping or passive lever structures, have slow response times and insufficient adjustment precision, making it difficult to actively and quickly compensate for these dynamic changes. This adjustment lag results in tension remaining inconsistent throughout the take-up process, failing to maintain an optimal range and consequently affecting the density and consistency of the final product.

[0005] Therefore, this utility model proposes a take-up tension adjustment mechanism for a continuous tin-plated copper wire production line to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a take-up tension adjustment mechanism for a continuous production line of tin-plated copper wire, aiming to improve the problems of low wire tension adjustment accuracy and difficulty in adapting to dynamic changes in continuous production in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a take-up tension adjustment mechanism for a continuous tin-plated copper wire production line, comprising a guide wheel bracket, a first guide wheel, a second guide wheel, a control box, and a lifting mechanism; The lifting mechanism includes a motor fixed to the guide wheel bracket and a sliding guide rail that is slidably connected in the vertical direction within the guide wheel bracket. Furthermore, a rotating rod is fixedly connected to the output end of the motor, the first guide wheel is fixedly connected to the sliding guide rail via a connecting column, and a locking block is fixedly connected to the end of the rotating rod. The locking block is slidably engaged in a horizontal groove opened in the sliding guide rail to convert the rotation of the rotating rod into the vertical sliding of the sliding guide rail. Preferably, it further includes an adjustment mechanism for adjusting the width of the second guide wheel groove, the adjustment mechanism being fixed to the guide wheel bracket; Preferably, the adjusting mechanism includes a screw, a guide ring, and a fixing ring. The guide ring and the fixing ring are fitted onto the screw, and the fixing ring is threadedly connected to the screw. The guide ring can move along the axial direction of the screw to abut against and lock the fixing ring. Preferably, the adjusting mechanism further includes a limiting block, which is fixedly connected to the end of the screw away from the guide ring; Preferably, the lifting mechanism further includes a spring and a fixing plate, the fixing plate being fixed to the guide wheel bracket, and the two ends of the spring being elastically connected between the fixing plate and the sliding guide rail, respectively; Preferably, the lifting mechanism further includes a support plate, and the motor is fixed to the outer wall of the guide wheel bracket via the support plate; Preferably, the guide wheel bracket has a vertical sliding groove for the sliding guide rail to slide in. Preferably, the first guide wheel and the second guide wheel are staggered in the vertical direction on the guide wheel bracket.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problem of inaccurate and fluctuating wire tension control in the prior art by setting up a lifting mechanism driven by a motor and buffered by a spring to drive the first guide wheel to move up and down, thereby achieving dynamic and stable adjustment of wire tension and ensuring winding quality.

[0009] 2. This utility model, by setting an adjustment mechanism consisting of a screw and an adjustable ring on the second guide wheel, realizes the rapid adjustment of the guide wheel groove width, solves the problems of poor versatility of the existing take-up mechanism, inability to adapt to different wire diameters and materials, and complex production changeover debugging, and achieves the effect of enhancing the applicability of the equipment and improving production changeover efficiency.

[0010] 3. This utility model converts the rotational motion driven by the motor into linear lifting motion through the ingenious cooperation of the rotating rod, the locking block and the sliding guide rail. This solves the problems of complex transmission structure and low reliability in some existing mechanisms, and achieves the effect of compact structure, short transmission chain and stable and reliable operation.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-4 An embodiment of this utility model is provided: a take-up tension adjustment mechanism for a continuous production line of tin-plated copper wire, including a guide wheel bracket 2 as an installation base, a first guide wheel 3 and a second guide wheel 4 disposed on the guide wheel bracket 2, a control box 1 electrically connected to the mechanism, and a lifting mechanism 6 for actively adjusting the height of the first guide wheel 3 to control the wire tension. Specifically, the lifting mechanism 6 includes a motor 601, which is fixed to the outer wall of the guide wheel bracket 2 via a support plate 608. The output end of the motor 601 is fixedly connected to a rotating rod 602. The lifting mechanism 6 also includes a sliding guide rail 604. The sliding guide rail 604 is slidably connected in a vertical sliding groove in the guide wheel bracket 2. The first guide wheel 3 is firmly fixed to the outside of the sliding guide rail 604 via a connecting column 605, so that the first guide wheel 3 can rise and fall synchronously with the sliding guide rail 604. To drive the sliding guide rail 604 to move, a locking block 603 is fixedly connected to the end of the rotating rod 602. The locking block 603 slides in a specially opened horizontal groove in the sliding guide rail 604. This structural design cleverly converts the rotational motion generated by the motor 601 driving the rotating rod 602 into the vertical sliding of the entire sliding guide rail 604, thereby driving the first guide wheel 3 to rise and fall. In addition, in order to ensure the smoothness and buffering effect of the lifting process, the lifting mechanism 6 also includes a fixed plate 607 and a spring 606. The fixed plate 607 is fixed on the guide wheel bracket 2, and the two ends of the spring 606 are elastically connected between the fixed plate 607 and the movable sliding guide rail 604, respectively. The adjustment mechanism 5 includes a screw 503, a guide ring 501 and a fixing ring 502 fitted on the screw 503. The fixing ring 502 is threadedly connected to the screw 503, and its axial position on the screw 503 can be adjusted by rotating the fixing ring 502. The guide ring 501 can move along the axial direction of the screw 503. After the fixing ring 502 is adjusted to a predetermined position, it abuts against and locks the fixing ring 502 to complete the setting of the groove width of the second guide wheel 4. To ensure the reliability of the adjustment, the adjustment mechanism 5 also includes a limiting block 504, which is fixedly connected to the end of the screw 503 away from the guide ring 501. This structure can effectively prevent the fixing ring 502 from slipping off the screw 503 during the adjustment process, ensuring the safety and convenience of operation. The lifting mechanism 6 also includes a spring 606 and a fixing plate 607. The fixing plate 607 is fixed to the guide wheel bracket 2. The two ends of the spring 606 are elastically connected between the stationary fixing plate 607 and the vertically movable sliding guide rail 604, respectively. To ensure reliable fixing of the motor 601, refer to... Figure 3 and Figure 4 The lifting mechanism 6 also includes a support plate 608. The motor 601 is firmly fixed to the outer wall of the guide wheel bracket 2 through the support plate 608, thereby providing a stable power source for the entire lifting mechanism 6. The guide wheel bracket 2 has a specially designed vertical sliding groove for the sliding guide rail 604 to slide. The outer contour of the sliding guide rail 604 slides and cooperates with the inner wall of the vertical sliding groove, ensuring the high stability and precise vertical guidance of the sliding guide rail 604 during movement. The first guide wheel 3 and the second guide wheel 4 are staggered in the vertical direction on the guide wheel bracket 2. When the wire passes through these two guide wheels, it will form a specific wire path. When the first guide wheel 3 is driven up and down by the lifting mechanism 6, the length and angle of the wire path change accordingly, thereby achieving the purpose of adjusting the tension.

[0015] Working principle: When it is necessary to adjust the take-up tension, the control box 1 sends a command to drive the motor 601 to rotate. The motor 601 drives the fixedly connected rotating rod 602 to rotate synchronously. The locking block 603 at the end of the rotating rod 602 slides in the horizontal groove of the sliding guide rail 604. The sliding of the locking block 603 converts the rotational motion of the rotating rod 602 into the vertical lifting motion of the sliding guide rail 604 in the guide wheel bracket 2. Since the first guide wheel 3 is fixedly connected to the sliding guide rail 604 through the connecting column 605, the first guide wheel 3 also rises and falls synchronously. By changing the wire path, the active adjustment of the take-up tension is realized. In this process, the spring 606 connected between the fixed plate 607 and the sliding guide rail 604 can absorb the instantaneous impact, making the tension change more stable. When it is necessary to produce copper wires of different diameters, the groove width of the second guide wheel 4 is preset by adjusting the mechanism 5. During operation, firstly rotate the fixing ring 502 that is threadedly connected to the screw 503, so that the fixing ring 502 moves axially to a position that matches the current wire diameter. Then tighten the guide ring 501 to abut against and lock the fixing ring 502, thus completing the adjustment of the groove width and ensuring that wires of different diameters can be stably transmitted in the appropriate groove.
