Description

Technical Field

[0001] This utility model belongs to the field of copper wire processing technology, specifically an automatic wire feeding device for copper wire straightening. Background Technology

[0002] Copper wire is a type of metallic material with excellent electrical and thermal conductivity, as well as excellent plasticity, making it easy to process by hot and cold pressure. It can be made into copper materials such as wires, strips, and tapes. Some copper wires that have been bent after use need to be straightened using straightening equipment when recycled and reused. Existing automatic wire feeding devices for copper wire straightening often have fixed spacing between the straightening rollers, or the adjustment method is relatively complex. It is difficult to make quick and accurate adjustments according to the straightening requirements of copper wires of different specifications. Moreover, after adjustment, displacement can easily occur due to the force applied during the copper wire straightening process, causing changes in the spacing between the straightening rollers, affecting the straightening effect and wire feeding stability, and reducing production efficiency and product quality.

[0003] Therefore, an automatic wire feeding device for straightening copper wire is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an automatic wire feeding device for copper wire straightening, which solves the problems of inconvenient adjustment of the straightening wheel spacing and instability after adjustment in existing devices, thereby improving the quality and efficiency of copper wire straightening and feeding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic wire feeding device for straightening copper wire, including a fixed frame, a wire roller symmetrically and rotatably connected to one side of the fixed frame, and an adjustment mechanism provided on the surface of the fixed frame;

[0006] The adjustment mechanism includes a movable plate symmetrically slidably connected inside the fixed frame. Several sets of straightening wheels are symmetrically arranged on the surface of the movable plate, and the straightening wheels rotate on the surface of the movable plate. The fixed frame has a groove for vertical sliding of the straightening wheels and the movable plate. Racks are symmetrically fixedly connected to both sides of the straightening wheels, and gears are meshed on the surface of the racks. The gears rotate inside the fixed frame. A worm gear is coaxially fixedly connected to one side of the gear, and a worm is meshed between two sets of vertically arranged worm gears.

[0007] Preferably, the two sets of worm gears are connected to each other by a connecting shaft, and one end of the worm gear passes through the interior of the fixed frame and is connected to a rotating component disposed on the surface of the fixed frame.

[0008] Preferably, a micrometer is installed at the top of the fixing frame to monitor the displacement of the moving plate.

[0009] Preferably, a wire feeding mechanism is provided on one side of the surface of the fixing frame. The wire feeding mechanism includes a wire feeding wheel rotatably connected to the surface of the fixing frame. A motor is fixedly installed on the rear side of the fixing frame, and the output end of the motor is connected to the wire feeding wheel.

[0010] Preferably, a pressure wheel is provided on the upper side of the wire feeding wheel, a slider is slidably connected inside the fixing frame near the pressure wheel, the pressure wheel is rotatably connected to the surface of the slider, and a spring in a compressed state is fixedly connected to the top of the slider.

[0011] Preferably, a pull rod is provided at the top of the fixing frame, and the bottom end of the pull rod penetrates through the surface of the fixing frame and is connected to the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an adjustment mechanism, through gear and rack transmission and worm gear linkage structure, allows for quick and synchronous adjustment of the distance between the two straightening wheels by simply turning the handwheel or starting the motor. Compared with the traditional manual adjustment method, the operation is more convenient. Utilizing the reverse self-locking characteristic of worm gear transmission, no additional locking components are needed to achieve automatic locking after the straightening wheel distance is adjusted, effectively avoiding the problem of distance changes caused by the force applied during copper wire straightening.

[0014] 2. By setting up a wire feeding mechanism, the wire feeding wheel driven by the motor can transport copper wire. The preload of the spring can adapt to copper wires of different hardness and specifications, ensuring that the clamping wheel always presses the copper wire tightly on the wire feeding wheel with appropriate pressure during the wire feeding process, preventing the copper wire from slipping and ensuring the stability and integrity of the wire feeding.

[0020] 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.

[0021] like Figures 1 to 4 As shown, this utility model provides an automatic wire feeding device for straightening copper wire, including a fixed frame 1, a wire roller 2 symmetrically rotatably connected to one side of the fixed frame 1, and an adjustment mechanism 3 provided on the surface of the fixed frame 1;

[0022] The adjusting mechanism 3 includes a movable plate 32 symmetrically slidably connected inside the fixed frame 1. Several sets of straightening wheels 31 are symmetrically arranged on the surface of the movable plate 32, and the straightening wheels 31 rotate on the surface of the movable plate 32. The fixed frame 1 has a groove inside for vertical sliding of the straightening wheels 31 and the movable plate 32. Racks 33 are symmetrically fixedly connected to both sides of the straightening wheels 31, and gears 34 are meshed with the surfaces of the racks 33. The gears 34 rotate inside the fixed frame 1. A worm gear 35 is coaxially fixedly connected to one side of the gear 34, and two sets of vertically arranged worm gears... A worm gear 36 is meshed between the wheels 35. By rotating the worm gear 36, the worm wheel 35 meshes with it. Since the worm wheel 35 is coaxially fixed with the gear 34, the gear 34 rotates accordingly. In turn, through meshing with the rack 33, it drives the moving plate 32 to slide vertically in the groove of the fixed frame 1, thereby achieving precise adjustment of the spacing of the straightening wheels 31. After the spacing of the straightening wheels 31 is adjusted to the correct position, the spacing of the straightening wheels 31 can be automatically locked without additional operation by utilizing the reverse self-locking characteristic of the transmission between the worm wheel 35 and the worm gear 36, ensuring the stability of the spacing of the straightening wheels 31.

[0023] like Figures 1 to 4 As shown, the two sets of worm gears 36 are connected to each other by a connecting shaft, and one end of the worm gear 36 passes through the interior of the fixed frame 1 and is connected to a rotating component set on the surface of the fixed frame 1. The rotating component facilitates the driving of the worm gear 36 to rotate.

[0024] A micrometer 5 is installed at the top of the fixed frame 1 to monitor the displacement of the moving plate 32, and the spacing of the straightening wheels 31 is precisely controlled according to the displacement displayed by the micrometer 5.

[0025] like Figures 1 to 4As shown, a wire feeding mechanism 4 is provided on one side of the surface of the fixed frame 1. The wire feeding mechanism 4 includes a wire feeding wheel 41 rotatably connected to the surface of the fixed frame 1. A motor 43 is fixedly installed on the rear side of the fixed frame 1, and the output end of the motor 43 is connected to the wire feeding wheel 41. When the motor 43 starts, it drives the wire feeding wheel 41 to rotate through a coupling. When the wire feeding wheel 41 rotates, it uses the friction between itself and the copper wire to drive the copper wire forward.

[0026] A pressure wheel 42 is provided on the upper side of the wire feeding wheel 41. A slider 44 is slidably connected inside the fixing frame 1 near the pressure wheel 42, and the pressure wheel 42 is rotatably connected to the surface of the slider 44. A spring 45 in a compressed state is fixedly connected to the top of the slider 44. Under the preload of the spring 45, the pressure wheel 42 can adaptively adjust according to the size of the copper wire, pressing the copper wire onto the wire feeding wheel 41 to prevent the copper wire from slipping.

[0027] A pull rod 46 is provided at the top of the fixed frame 1, and the bottom end of the pull rod 46 passes through the surface of the fixed frame 1 and is connected to the slider 44. By pulling the pull rod 46, the position of the pressure wheel 42 can be adjusted, so that the copper wire can be placed on the surface of the wire feeding wheel 41.

[0028] Working principle and process: Before straightening the copper wire, the operator rotates the rotating part connected to the worm 36 according to the diameter and material of the copper wire to be straightened. The rotation of the worm 36 drives the worm wheel 35 that meshes with it. Since the worm wheel 35 is coaxially fixed with the gear 34, the gear 34 rotates accordingly. Then, through meshing with the rack 33, it drives the moving plate 32 to slide vertically in the groove of the fixed frame 1, so as to achieve precise adjustment of the spacing of the straightening wheels 31. During the adjustment process, the operator can observe the micrometer 5 at the top of the fixed frame 1 and accurately control the spacing of the straightening wheels 31 according to the displacement shown by the micrometer 5. After the adjustment is completed, the copper wire to be straightened is introduced from the guide roller 2 on one side of the fixed frame 1 and passes through the straightening channel composed of the straightening wheels 31 in sequence. When the copper wire passes through the straightening wheels 31, it is squeezed and stretched by the straightening wheels 31, gradually eliminating its own bending and completing the straightening process. The straightened copper wire enters the wire feeding mechanism 4. The motor 43 starts and drives the wire feeding wheel 41 to rotate through the coupling. When the wire feeding wheel 41 rotates, it uses the friction between itself and the copper wire to drive the copper wire forward. At the same time, the clamping wheel 42, under the preload of the spring 45, presses the copper wire onto the wire feeding wheel 41 to prevent the copper wire from slipping.
