Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire processing technology, and in particular to an automatic wire feeding device and a wire length cutting device. Background Technology
[0002] In high-speed wire rod production lines, after the rolled coils are bundled, to prevent the bundling line from shifting, it is usually necessary to use a wire rod with a diameter of [missing information]. Galvanized iron wire is used to circumferentially bind the bundling lines on the coil. Practice shows that the specified wire length for this binding operation is about 5.2m.
[0003] Currently, the wire used in production lines is mostly in 50kg rolls. In practice, these rolls need to be manually cut to the specified lengths. Operators primarily rely on wire cutters for this, but this manual cutting method has significant drawbacks: Firstly, the large weight of each roll and the large number of required cuts result in a massive workload, consuming significant manpower and severely impacting the overall efficiency of the production line. Secondly, it's difficult to precisely control the wire length during manual cutting, leading to inconsistent lengths that don't meet standardized production requirements. Oversized wire directly wastes materials and increases production costs, while undersized wire cannot meet bundling needs, potentially causing quality issues such as bundling line shifting, thus affecting the stability of subsequent production stages.
[0004] Therefore, there is an urgent need to propose an automatic wire feeding device and a wire length cutting device to solve the above problems. Utility Model Content

[0016] In some optional embodiments, the winding frame includes a rotary table and a plurality of winding skeletons. The rotary table is connected to the output end of the rotary drive assembly.

[0021] This utility model provides an automatic wire feeding device and a wire length cutting device, including a driven winding mechanism and an active winding mechanism. The driven winding mechanism includes a core frame rotatably connected to a base, on which the wire coil can be sleeved. The active winding mechanism includes a rotary drive assembly and a winding frame. The winding frame is rotatably connected to the base and spaced apart from the core frame. The rotary drive assembly is disposed on the base, and its output end is driven to the winding frame to drive the winding frame to rotate, so that the wire is wound onto the winding frame.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides an automatic wire feeding device, including a driven winding mechanism and an active winding mechanism 2. The driven winding mechanism includes a core frame 3, which is rotatably connected to a base 1, and the wire can be wound onto the core frame 3. The active winding mechanism 2 includes a rotary drive assembly 21 and a winding frame 22, which is rotatably connected to the base 1 and spaced apart from the core frame 3. The rotary drive assembly 21 is disposed on the base 1, and its output end is connected to the winding frame 22 for driving the winding frame 22 to rotate so that the wire is wound onto the winding frame 22.
[0033] During production, the finished wire is first wound onto the core frame 3; then the free end of the wire is pulled out and fixed at any position on the winding frame 22; then the rotation drive assembly 21 is started to drive the winding frame 22 to rotate, so that the wire is wound on the winding frame 22; finally, multiple turns of wire are cut at any position around the winding frame 22 to obtain multiple wires of a specified length.
[0034] The specified wire length is defined by the length of one loop of the wire wound on the winding frame 22. By simultaneously cutting all the wires on the winding frame 22 at any position around its circumference, multiple wires of the same length can be obtained, improving the consistency of the wire cutting length. This reduces material waste caused by wires exceeding the specified length and ensures that the wire length is sufficient to meet bundling requirements. In addition, by using an automatic wire feeding device, the wire loop can be automatically enlarged onto the winding frame 22, resulting in multiple wires of the specified length. This improves the automation level and overall efficiency of wire cutting and reduces manual workload.
[0035] In some alternative embodiments, the driven winding mechanism further includes a damping structure disposed between the base 1 and the core frame 3 to generate resistance opposite to the wire unwinding direction, preventing the core frame 3 from unwinding too much wire under inertia.
[0036] In some alternative embodiments, the damping structure includes a deceleration bolt threaded to the core frame 3. At least a portion of the deceleration bolt contacts the base 1, generating frictional resistance, thereby applying a certain resistance to the core frame 3. It has a simple structure, low cost, and strong practicality.
[0037] Optionally, the damping structure may include, but is not limited to, magnetic dampers or pneumatic dampers, which are not limited here.
[0038] In some optional embodiments, the driven winding mechanism further includes a driven bearing, the outer ring of which is fixedly connected to the base 1, and the inner ring of which is fixedly connected to the shaft of the core frame 3. By providing a driven bearing, the smoothness of the rotation of the core frame 3 can be improved, which helps to reduce wear and extend the service life of the driven winding mechanism.
[0039] As is easily understood, the active winding mechanism 2 also includes a control switch, which is electrically connected to the rotary drive assembly 21 and is used to control the start and stop of the rotary drive assembly 21 to drive the winding frame 22 to rotate or stop rotating.
[0040] In some optional embodiments, the rotary drive assembly 21 includes a drive motor and a reduction mechanism. A driven gear is fixedly connected to the shaft of the winding frame 22. The reduction mechanism is driven by the output end of the drive motor, and a driving gear is driven by the output end of the reduction mechanism. The driving gear meshes with the driven gear to drive the winding frame 22 to rotate. By providing a reduction mechanism, the rotational speed can be reduced and the output torque increased, thereby improving the load capacity of the rotary drive assembly 21.
[0041] Optionally, the reduction mechanism may include, but is not limited to, a gear reduction mechanism or a worm gear reduction mechanism, which are not limited herein.
[0042] In some optional embodiments, the rotary drive assembly 21 further includes a braking mechanism, which is brakely connected to the drive motor or reduction gear to stop the winding frame 22 from rotating. The braking mechanism can quickly brake the rotating load and prevent the winding frame 22 from continuing to rotate under inertia.
[0043] Optionally, the braking mechanism may include, but is not limited to, an electromagnetic brake or a spring brake, which is not limited here.
[0044] In some optional embodiments, the active winding mechanism 2 further includes an active bearing, the outer ring of which is fixedly connected to the base 1, and the inner ring of which is fixedly connected to the shaft of the winding frame 22. By providing an active bearing, the smoothness of the rotation of the winding frame 22 can be improved, which helps to reduce wear and extend the service life of the active winding mechanism 2.
[0045] In some optional embodiments, the winding frame 22 includes a rotary table 221 and multiple winding bobbins 222. The rotary table 221 is connected to the output end of the rotary drive assembly 21. The multiple winding bobbins 222 are evenly spaced on the rotary table 221 with the rotation center of the rotary table 221 as the center. Wire can be wound around the multiple winding bobbins 222 circumferentially. The multiple winding bobbins 222 form a cylindrical winding frame. Multiple turns of wire can be stacked around the cylindrical winding frame circumferentially, thereby increasing the number of wires cut in a single operation and improving the overall efficiency of wire cutting. The cylindrical winding frame can maximize the use of space, which is beneficial to improving the space utilization rate of the automatic wire feeding device.
[0046] Of course, in other embodiments, the winding frame 22 may also be square or elliptical, and this is not limited here.
[0047] In some optional embodiments, the winding frame 22 further includes support frames 223 corresponding to the winding skeletons 222. Multiple support frames 223 are evenly spaced and connected circumferentially to the rotary table 221, with each support frame 223 extending radially along the rotary table 221. The winding skeletons 222 are erected on their corresponding support frames 223. Connecting the winding skeletons 222 to the support frames 223 increases the winding circumference, meeting the wire cutting length requirements. Simultaneously, the spaced support frames 223 help reduce the weight of the winding frame 22, thereby reducing the manufacturing cost and load of the active winding mechanism 2.
[0048] In some optional embodiments, each winding skeleton 222 is adjustablely connected to the support skeleton 223 along the radial position of the rotary table 221. By adjusting the radial position of the multiple winding skeletons 222 along the rotary table 221, the circumference of the wire winding can be adjusted, thereby adjusting the length of the wire cutting, which is beneficial to improving the versatility and flexibility of the automatic wire feeding device.
[0049] In some alternative embodiments, each support frame 223 is provided with multiple mounting positions spaced apart along its length, and the winding frame 222 can be detachably connected to any mounting position to adjust the circumference of the wire winding.
[0050] In other embodiments, the winding skeleton 222 is slidably connected to the support skeleton 223 along its length direction. The active winding mechanism 2 also includes an adjustment drive component, the output end of which is connected to each winding skeleton 222 for driving the winding skeleton 222 to slide along the length direction of the support skeleton 223, so as to realize the automatic adjustment of the wire winding circumference.
[0051] In some optional embodiments, this embodiment also provides a wire length cutting device, including a cutting device and an automatic wire feeding device of any of the above embodiments. The cutting device is configured to cut multiple turns of wire wound on the winding frame 22 from the same position. By using an automatic wire feeding device, the automation level of wire cutting can be improved, the overall efficiency of wire cutting can be improved, and the amount of manual labor can be reduced; the consistency of wire cutting length can be improved, material waste can be reduced, and bundling requirements can be met.
[0052] Optionally, the cutting device may include, but is not limited to, wire cutters, hydraulic cutters, pneumatic cutters or laser cutters, and is not limited herein.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
