Description

Technical Field

[0001] This application belongs to the field of flux-cored wire layer winding technology, and specifically relates to a flux-cored wire layer winding machine. Background Technology

[0002] Flux-cored welding wire (also known as powder-cored welding wire or tubular welding wire) is a composite welding wire made of materials with good plasticity, such as low-carbon steel or low-alloy steel, consisting of a surface layer and an internal flux core. It is widely used in the welding field. In the preparation process of flux-cored welding wire, the layer winding operation is one of the key processes. Its function is to evenly wind the continuously produced welding wire onto a spool for storage, transportation, and subsequent use.

[0003] In the prior art, there are already layer winding devices that improve the layer winding effect through tension adjustment mechanisms (such as the "A Layer Winding Device for Flux-Cored Wire" disclosed in Chinese Patent CN220115919U). This device can dynamically adjust the tension of the flux-cored wire through the cooperation of a compression spring, a sliding plate, and a guide wheel, and drives the guide wheel to reciprocate by a servo motor-driven screw, thereby improving the uniformity of layer winding. However, in practical applications, such devices still suffer from low efficiency in spool loading and unloading: existing devices typically use a threaded chuck to fix the spool (such as the threaded connection between the convex placement post and the chuck in CN220115919U), which requires repeated rotation of the chuck during loading and unloading, making the operation cumbersome and affecting the efficiency of spool changing.

[0004] Therefore, in view of the shortcomings of existing flux-cored wire winding devices in terms of the efficiency of loading and unloading on the wire spool, there is an urgent need to develop a new type of flux-cored wire winding machine that is easy to operate and has reliable clamping. Utility Model Content

[0005] This application provides a flux-cored wire layer winding machine, which simplifies the bobbin fixing steps and improves the assembly and disassembly efficiency by setting a quick assembly and disassembly mechanism, thereby solving the problems of cumbersome operation and low efficiency in the assembly and disassembly process of existing flux-cored wire layer winding machines.

[0006] To achieve the above objectives, this application provides a flux-cored welding wire winding machine, including a base, a fixed seat fixedly disposed on the base, a first motor fixedly disposed at the top of the fixed seat, the first motor being used to drive a winding assembly, the winding assembly being mounted on the fixed seat; The winding assembly includes a winding roller, which is rotatably mounted on a fixed base and connected to the output end of a first motor. Four first rotating seats are evenly arranged circumferentially on the inner wall of the winding roller at the end furthest from the fixed base. Clamping and limiting rods are rotatably mounted on the four first rotating seats. A first connecting rod is rotatably mounted on the end of the clamping and limiting rod closest to the winding roller. A slide table is rotatably mounted on the end of the first connecting rod furthest from the first rotating seats. A limiting groove for the slide table to slide is formed on the inner wall of the winding roller. A second connecting rod is fixedly mounted on the slide table. A slide table is mounted on the end of the second connecting rod closest to the fixed base. Four connecting slots penetrating the inner wall are formed on the end of the winding roller closest to the fixed base. Clamping and limiting discs are slidably mounted on the winding roller through the four connecting slots. The clamping and limiting discs are also connected to the slide tables.

[0007] In one embodiment, a locking component is provided between the winding assembly and the fixed base. The winding assembly also includes a boss at the end of the winding roller near the fixed base. A first compression spring is provided between the boss and the clamping limit plate. The locking component is used to lock the clamping limit plate.

[0008] In one embodiment, the locking assembly includes a limiting ring and a second rotating seat, wherein the limiting ring is fixedly disposed on the side of the clamping limiting plate near the fixed seat; The second rotating seat is mounted on the fixed seat. A second connecting rod is rotatably mounted inside the second rotating seat. The end of the second connecting rod away from the fixed seat is engaged with a limiting ring, and the other end abuts against the pressure table. The pressure table is slidably mounted inside the fixed seat, and a pressing block is also mounted on the pressure table.

[0009] In one embodiment, an adjusting slide is provided in the fixed base, and the pressure table is slidably disposed in the adjusting slide. An adjusting spring is provided between the top of the adjusting slide and the pressure table; a torsion spring is provided on the connecting shaft between the second connecting rod 42 and the second rotating seat.

[0010] In one embodiment, a material guiding mechanism is also included. The material guiding mechanism includes a limiting slide, which is fixedly mounted on a base. A lead screw is rotatably mounted inside the limiting slide, and a vertical compartment is threaded onto the lead screw. The vertical compartment is slidably mounted inside the limiting slide.

[0011] In one embodiment, a pressure regulating component is provided at the end of the vertical compartment away from the limiting slide. The pressure regulating component includes a core groove that extends through the side of the vertical compartment. A slider is slidably disposed in the core groove, and a guide roller is rotatably disposed below the slider. A second compression spring is disposed between the upper part of the slider and the top of the vertical compartment.

[0012] In one embodiment, the material guiding mechanism further includes a second motor, which is fixedly mounted at the end of the limiting slide and connected to the lead screw.

[0013] In one embodiment, the limiting slide, the limiting slide chamber, and the core groove are all T-shaped grooves.

[0014] Compared with the prior art, the beneficial effects of this application are: 1. Efficient and convenient spool installation and removal: Through the linkage structure of the clamping limit rod, the first connecting rod, and the slide of the winding assembly, combined with the elastic reset of the first compression spring and the pressing and unlocking design of the locking assembly, the spool can be quickly installed and removed, significantly improving the spool changing efficiency of flux-cored welding wire layer winding operations.

[0015] 2. Stable and reliable clamping: The synergistic effect of the clamping limit rod and the clamping limit plate ensures that the bobbin is firmly fixed during the layer winding process, avoiding layer winding misalignment or falling off due to loosening, and ensuring the quality of layer winding.

[0016] 3. High uniformity of layer winding: The feeding mechanism drives the lead screw to rotate through the second motor, which drives the vertical bin to move back and forth along the limit slide, so that the flux-cored welding wire is evenly distributed on the take-up roller; at the same time, the slider of the pressure adjustment component dynamically adjusts the tension of the welding wire under the action of the second compression spring, keeping it taut and effectively avoiding loosening, uneven winding and other phenomena.

[0017] 4. Safe and flexible operation: The locking component's limit ring and the second link's locking design prevent the clamping limit plate from accidentally resetting when it is not unlocked, ensuring the safety of the disassembly process; the rotating design of the guide roller reduces frictional wear between the welding wire and the equipment, extending the equipment's service life.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] See Figures 1 to 6 As shown, the flux-cored wire winding machine provided in this application includes a base 1, a fixed seat 3 is fixedly installed on the base 1, a first motor 5 is fixedly installed at the top of the fixed seat 3, the first motor 5 is used to drive the winding assembly 2, and the winding assembly 2 is installed on the fixed seat 3.

[0023] During the flux-cored wire layer winding operation, the spool is first placed on the winding assembly 2. After the spool is placed, the winding assembly 2 engages and secures it. Once the spool is secured, the first motor 5 is started to drive the winding assembly 2 to rotate. During the rotation of the winding assembly 2, the spool rotates synchronously, and the flux-cored wire is layered during rotation. After the flux-cored wire layer winding is completed, the spool is moved to the end away from the fixing seat 3 to remove it.

[0024] The winding assembly 2 includes a winding roller 21, which is rotatably mounted on a fixed base 3 and connected to the output end of a first motor 5. Four first rotating seats 23 are evenly arranged around the circumference of the inner wall of the winding roller 21 at the end furthest from the fixed base 3. Clamping and limiting rods 27 are rotatably mounted on the four first rotating seats 23. A first connecting rod 26 is rotatably mounted at the end of the clamping and limiting rods 27 closest to the winding roller 21. A first connecting rod 26 is rotatably mounted at the end of the first connecting rod 26 furthest from the first rotating seats 23. A slide table 211 is provided, and a limiting groove 25 for sliding the slide table 211 is provided on the inner wall of the take-up roller 21. A second connecting rod 28 is fixedly provided on the slide table 211, and a slide seat 212 is provided at the end of the second connecting rod 28 near the fixed seat 3. Four connecting slots 24 penetrating the inner wall are provided at the end of the take-up roller 21 near the fixed seat 3. A clamping limiting plate 29 is slidably provided on the take-up roller 21 through the four connecting slots 24. The clamping limiting plate 29 is also connected to the slide seat 212.

[0025] After the spool completes the layering of the flux-cored welding wire, the first motor 5 is stopped, and the spool is pushed towards the side closer to the fixed base 3. During this pushing process, the spool pushes the clamping limiting plate 29 to slide along the connecting groove 24 towards the side closer to the fixed base 3. As the clamping limiting plate 29 slides, it drives the second connecting rod 28 to move via the slide block 212. During the movement of the second connecting rod 28, it drives the slide table 211 to move inward along the limiting slide groove 25. The movement of the slide table 211 causes the first connecting rod 26 to drive the clamping limiting rod 27 to rotate inward around the first rotating base 23 (i.e., each limiting rod 27 moves closer to each other). The inward rotation of the clamping limiting rod 27 gradually releases its clamp on the spool. When the clamping limiting plate 29 slides to the locking point and locks, the clamping limiting rod 27 completely releases its limit on the spool, at which point the spool can be freely removed. The entire device is easy to operate and effectively improves the efficiency and safety of flux-cored welding wire layering operations.

[0026] Optionally, a locking component 4 is provided between the winding assembly 2 and the fixed base 3. The winding assembly 2 also includes a boss 48 at the end of the winding roller 21 near the fixed base 3. A first compression spring 210 is provided between the boss 48 and the clamping limit plate 29. The locking component 4 is used to lock the clamping limit plate 29.

[0027] During the disassembly of the bobbin, the first compression spring 210 is gradually compressed and stores elastic potential energy by moving the clamping limit plate 29 inward. When the locking component 4 is pressed, the locking state of the clamping limit plate 29 is released, the first compression spring 210 releases energy, and pushes the clamping limit plate 29 to quickly reset, ensuring fast and accurate disassembly and installation of the bobbin, further optimizing the bobbin replacement operation process and improving the overall efficiency of the core winding operation.

[0028] In this embodiment, when the spool needs to be installed, the spool is first placed on the take-up roller 21 and in contact with the clamping limit plate 29. Then, the locking component 4 is manually pressed down. At this time, the locking component 29 will release the locking state of the clamping limit plate 29. After the locking state is released, the clamping limit plate 29 moves away from the fixed seat 3 under the elastic force of the first compression spring 210. The movement of the clamping limit plate 29 drives the slide 212 and the second connecting rod 28 to move outward synchronously, thereby pushing the slide table 211 to slide outward along the limit slide groove 25. Finally, the clamping limit rod 27 rotates outward around the first rotating seat 23. During the outward rotation of the clamping limit rod 27, the clamping limit plate gradually clamps the spool to ensure that the spool is firmly fixed on the take-up roller 21 and to prevent loosening during the winding process.

[0029] Optionally, the locking assembly 4 includes a limiting ring 41 and a second rotating base 43, wherein the limiting ring 41 is fixedly disposed on the side of the clamping limiting plate 29 near the fixed base 3; The second rotating seat 43 is mounted on the fixed seat 3. A second connecting rod 42 is rotatably mounted inside the second rotating seat 43. The end of the second connecting rod 42 away from the fixed seat 3 is engaged with the limiting ring 41, and the other end abuts against the pressure table 46. The pressure table 46 is slidably mounted inside the fixed seat 3. A pressing block 45 is also mounted on the pressure table 46.

[0030] In this embodiment, the first compression spring 210 is connected between the limiting ring 41 and the boss 48. When the spool with the flux-cored welding wire layer wound has been removed, the spool pushes the clamping limiting plate 29 to slide inward. During the inward sliding of the clamping limiting plate 29, the limiting ring 41 gradually approaches the second connecting rod 42. Finally, the limiting ring 41 contacts and engages with the second connecting rod 42, thereby locking the clamping limiting plate 29 and preventing it from sliding outward under the action of the first compression spring 210 before the lock is released.

[0031] Optionally, an adjusting slide is provided inside the fixed base 3, and the pressure table 46 is slidably disposed inside the adjusting slide. An adjusting spring 47 is provided between the top of the adjusting slide and the pressure table 46. A torsion spring is provided on the connecting shaft between the second connecting rod 42 and the second rotating base 43.

[0032] In this embodiment, when the spool needs to be installed onto the take-up roller 21, the pressing block 45 is manually pressed down. During the downward movement of the pressing block 45, the pressing table 46 is pushed downward within the adjusting slide chamber. As the pressing table 46 slides downward, it drives the second connecting rod 42 to rotate counterclockwise around the second rotating seat 43 (e.g., ...). Figure 5 As shown, while the second link 42 rotates, the end of it close to the clamping limit plate 29 is gradually raised upwards. During the raising process, the engagement with the limit ring 41 is gradually released, and finally the locking component 4 is unlocked, ensuring that the clamping limit plate 29 is smoothly reset under the action of the first compression spring 410, and the spool can be quickly installed.

[0033] After the adjusting spring 47 slides down the pressure plate 46, it automatically rebounds, restoring its initial tension. This ensures the stable reset of the second connecting rod 42 under the action of the torsion spring, adjusting the position of the second connecting rod 42 and providing a stable locking state for subsequent disassembly of the spool. Additionally, the torsion spring ensures that when the pressing block 45 is not pressed, the end of the second connecting rod 42 furthest from the fixed base 3 is essentially flush with the limiting ring 41, ensuring that the limiting ring 41 can engage with the hook of the second connecting rod 42 when it moves.

[0034] Optionally, it also includes a material guiding mechanism 6, which includes a limiting slide 61. The limiting slide 61 is fixedly mounted on the base 1. A lead screw 62 is rotatably mounted inside the limiting slide 61. A vertical compartment 64 is threaded onto the lead screw 62 and is slidably mounted inside the limiting slide 61.

[0035] In this embodiment, when the flux-cored welding wire is layered, the drive screw 62 rotates, which can drive the vertical chamber 64 to move back and forth along the limiting slide chamber 41. The movement of the vertical chamber 64 makes the flux-cored welding wire evenly distributed on the take-up roller 21 during the layering process, avoiding jamming caused by uneven winding.

[0036] Optionally, the material guiding mechanism 6 also includes a second motor 63, which is fixedly mounted at the end of the limiting slide 61 and connected to the lead screw 62.

[0037] In this embodiment, when the flux-cored welding wire is wound in layers, the lead screw 62 is driven to rotate by the second motor 63.

[0038] Optionally, a pressure regulating component is provided at the end of the vertical compartment 64 away from the limiting slide 61. The pressure regulating component includes a core groove 68, which is opened through the side of the vertical compartment 64. A slider 65 is slidably arranged in the core groove 68. A guide roller 67 is rotatably arranged below the slider 65. A second compression spring 66 is arranged between the upper part of the slider 65 and the top of the vertical compartment 64.

[0039] In this embodiment, as the flux-cored wire passes through the flux-cored groove 68, the slider 65 dynamically adjusts the tension of the flux-cored wire under the action of the second compression spring 66, ensuring that the flux-cored wire remains taut between the slider 65 and the guide roller 67 during the layer winding process, preventing loosening. The guide roller 67 rotates synchronously when in contact with the flux-cored wire, ensuring a smooth transition of the flux-cored wire, reducing frictional loss, and improving the layer winding quality.

[0040] Optionally, the limiting slide 25, the limiting slide 61, and the core groove 68 are all T-shaped grooves. The T-shaped groove can limit the sliding parts inside to prevent the sliding parts from shifting or getting stuck.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
