Description

Technical Field

[0001] This utility model relates to the technical field of welding wire feeding equipment, specifically to an adjustable automatic wire feeding device. Background Technology

[0002] In the field of welding, welding equipment uses a wire feeding device to continuously feed wire to the welding torch, thereby achieving automated welding. The wire feeding device typically consists of a base plate, a pressure roller, a feed roller, and a drive assembly. The drive assembly is mounted on the base plate and drives the pressure roller and feed roller. The automatic wire feeding device allows the welding wire to pass through the gap between the pressure roller and the feed roller, and the frictional force propels the wire forward, thus achieving stable wire feeding.

[0003] In existing technologies, the pressure roller wears out quickly due to constant friction with the welding wire and needs to be replaced promptly. Furthermore, the pressure roller is fixed to the bottom with bolts and nuts, requiring the entire wire feeding device to be disassembled, which is inconvenient. Detachable pressure rollers, due to their detachable design, cannot adjust the tension between themselves and the wire feeding roller, which negatively impacts the quality of wire feeding. In addition, the angle at which the welding wire enters the wire feeding device varies depending on the number of turns and the amount used, necessitating adjustments to the guide angle to match the wire feeding device. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the inconvenience of operation of the existing wire feeding device, thereby providing an adjustable automatic wire feeding device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An adjustable automatic yarn feeding device includes a yarn feeding frame, a main drive unit, a yarn feeding structure, and a yarn feeding reel. The main drive unit is installed inside the yarn feeding frame and drives the yarn feeding structure to move. The yarn feeding structure is installed on one side of the yarn feeding frame. The yarn feeding reel is rotatably mounted on one end of the top of the yarn feeding frame and is located on the same side as the yarn feeding structure. A yarn guide is also provided between the yarn feeding structure and the yarn feeding reel. The yarn feeding structure includes two horizontally parallel pressure rollers, two horizontally parallel yarn feeding rollers, a drive structure, a yarn feeding base plate, and a support. The component comprises a pressure roller, a feed roller, a drive structure, and a support member, all mounted on a feed base plate. The pressure roller and the feed roller are arranged vertically side by side, with the pressure roller positioned above the feed roller. The drive structure includes a main drive gear coaxially connected to the main drive member and two driven gears coaxially arranged with the two feed rollers respectively. Both driven gears mesh with the main drive gear and are positioned relative to the main drive gear. The support member is positioned at both ends corresponding to the gap between the pressure roller and the feed roller and is located between the two sets of pressure rollers and feed rollers.

[0007] By adopting the above technical solution, the welding wire is led out from the wire feeding reel and fed through the wire feeding structure. The main drive unit controls the wire feeding structure to realize the wire feeding movement. During the wire feeding process, the welding wire passes through two sets of pressure rollers and the wire feeding rollers. A support is set between the two sets of pressure rollers to prevent the wire from collapsing in the middle due to excessive stroke during the wire feeding process. The pressure rollers adopt a detachable structure, which can be replaced in a timely and convenient manner after wear without disassembling the entire wire feeding structure. The wire feeding rollers opposite to the pressure rollers can be adjusted within a small range, thereby controlling the distance between the wire feeding rollers and the pressure rollers and adjusting the tightness of the welding wire. After being led out from the wire feeding reel, the welding wire first passes through the wire guide, which can adapt to welding wires of different angles and smoothly guide the welding wire into the wire feeding structure, facilitating subsequent wire guiding operations.

[0008] Furthermore, the drive structure also includes a wire feeding shaft, on which the wire feeding wheel and the driven gear are both mounted. The wire feeding shaft has a locking nut and a locking bolt at both ends. The locking bolt passes through the wire feeding shaft and is threadedly connected to the locking nut. The driven gear has two positioning pins with parallel axes extending from the side near the wire feeding wheel. The wire feeding wheel has two through positioning holes corresponding to these two pins.

[0009] By adopting the above technical solution, the wire feeding wheel and the driven gear installed on the wire feeding shaft can rotate synchronously due to the positioning pin and the positioning hole; the setting of the locking bolt and locking nut limits the position of the wire feeding wheel and the driven gear on the wire feeding shaft, ensuring that the two are in close contact and avoiding back-and-forth displacement during rotation, which would affect the wire feeding effect.

[0010] Furthermore, an adjusting component is also installed on the wire feeding shaft. The adjusting component includes an adjusting seat, an adjusting shaft, and a control seat. The wire feeding shaft is rotatably mounted and passes through the adjusting seat. The adjusting seat is vertically slidably disposed within the wire feeding base plate. An adjusting groove is provided on the wire feeding base plate corresponding to the adjusting seat. The axis of the adjusting shaft is perpendicular to the axis of the wire feeding shaft and is disposed along the sliding direction of the adjusting seat. The adjusting shaft is also threadedly connected to the control seat. The control seat extends and is disposed on the side of the adjusting seat away from the main drive gear. Both ends of the adjusting shaft are rotatably mounted on the wire feeding base plate. An adjusting handle extends from the bottom end of the adjusting shaft.

[0011] By adopting the above technical solution, the rotating adjustment handle controls the rotation of the adjustment shaft, which drives the control seat to slide. The adjustment seat, which is integrated with the control seat, slides up and down in the adjustment groove, thereby realizing the up and down movement of the wire feeding shaft in the adjustment seat. During this process, the driven gear is always meshed with the main drive gear. Therefore, the range of the adjustment seat that can slide up and down is small, and the tension between the pressure wheel and the wire feeding wheel can only be adjusted within a small range.

[0012] Furthermore, the wire feeding base plate is also provided with two parallel wire pressing brackets. Each wire pressing bracket is rotatably connected to the wire feeding base plate, and a hinge shaft is provided at one end of the two wire pressing brackets that are close to each other. The wire pressing brackets are correspondingly arranged with the wire pressing wheel. The wire pressing wheel is rotatably installed in the wire pressing bracket. A mounting pin for fixing the wire pressing wheel is provided on the wire pressing bracket. The mounting pin passes through the wire pressing bracket and the wire pressing wheel and is engaged with the wire feeding base plate. A locking groove is provided around the side of the mounting pin near the wire feeding base plate. A locking ring is provided on the wire pressing bracket corresponding to the locking groove.

[0013] Furthermore, the two ends of the wire feeding base plate also extend with movable seats relative to the wire pressing brackets. A clamping handle is rotatably mounted on the movable seat. The clamping handle includes an operating handle, a movable handle, and a movable shaft. One end of the movable shaft is fixedly set with the operating handle, and the other end of the movable shaft is rotatably connected to the wire feeding base plate. The rotation axis of the movable shaft is set along the length direction of the wire feeding base plate. The movable handle is slidably set inside the operating handle and sleeved outside the movable shaft. A handle spring is also sleeved on the movable shaft. The handle spring is installed inside the movable handle, and both ends of the handle spring are respectively connected to the inner top wall of the operating handle and the inner bottom wall of the movable handle. The two ends of the wire pressing brackets that are far apart from each other extend with clamping seats corresponding to the clamping handles. The clamping seats have a forward-opening movable groove, and the top of the clamping seats has a V-shaped clamping groove that mates with the bottom of the movable handle.

[0014] By adopting the above technical solution, the pressure roller is installed in the pressure roller bracket and fixed by the installation pin. The pressure roller bracket with the pressure roller is then fixed to the wire feeding base plate by the clamping handle. When disassembly is required, the operating handle is rotated to disengage from the movable groove, and then the pressure roller bracket is rotated upward. Finally, the installation pin is removed to take out the pressure roller. The movable seat provides rotation for the movable shaft and provides limit support for the wire feeding bracket. The cooperation between the movable handle and the clamping groove locks the pressure roller after installation.

[0015] Furthermore, the wire feeding base plate extends with multiple mounting posts on the side near the wire feeding frame, and the wire feeding frame has arc-shaped mounting grooves corresponding to the mounting posts. The mounting posts are also fitted with coaxial mounting washers, which are placed between the wire feeding base plate and the wire feeding frame. The mounting posts are also threaded with mounting nuts, which are placed on the side of the wire feeding frame away from the wire feeding base plate. An outer cover is also snapped onto the outside of the wire feeding base plate.

[0016] By adopting the above technical solution, the mounting column and the mounting groove cooperate to fix the wire feeding base plate on the wire feeding machine frame. Due to the arc design of the mounting groove, the wire feeding base plate can be deflected at a certain angle on the wire feeding machine frame, thereby better adapting to the angle at which the wire feeding spool leads out the wire. The outer cover can protect the structure on the wire feeding base plate and block dust, preventing the welding wire from being covered with dust during the wire feeding process and affecting the subsequent welding quality. On the other hand, the outer cover can also be used to lock the clamping handle to ensure the stability of the wire pressing wheel installation.

[0017] Furthermore, the support component includes a support tube and a support base. The axis of the support tube is arranged along the length direction of the wire feeding base plate. A wire feeding hole is opened through the middle of the support tube. Relief grooves are provided at both ends of the support tube corresponding to the wire pressing wheel and the wire feeding wheel. The support tube is embedded in the support base, and the support base is fixed to the wire feeding base plate by screws.

[0018] By adopting the above technical solution, the welding wire also passes through the support component during the conveying process. On the one hand, it can reduce surface dust by rubbing against the wall of the support tube. On the other hand, it avoids long sections of suspension during the conveying process, which would cause the welding wire to loosen and affect the accuracy of subsequent wire feeding.

[0019] Furthermore, the wire guide includes two opposing arc-shaped wire guide blocks, which are rotatably connected to the wire feeder frame. A rotating block extends from the middle of the side of the two wire guide blocks that is far apart from each other and is rotatably connected to the wire feeder frame. A plurality of wire guide springs are also provided on the side of the two wire guide blocks that is far apart from each other. The wire guide springs are perpendicular to the side of the wire guide blocks. One end of the wire guide spring is fixed to the side of the wire guide block, and the other end is fixed to the wire feeder frame.

[0020] By adopting the above technical solution, the wire guide block and the wire guide spring can adapt to welding wires entering the wire feeding structure at different angles, and the reaction force of the wire guide spring can make the welding wires smoothly fed into the wire feeding structure.

[0021] In summary, the technical solution of this utility model has the following advantages:

[0022] 1. The adjustable automatic wire feeding device provided by this utility model, during the wire feeding process, the welding wire passes through two sets of wire pressing rollers and wire feeding rollers in succession. A support is set between the two sets of wire pressing rollers to prevent the middle part of the welding wire from collapsing due to excessive stroke during the wire feeding process.

[0023] 2. The adjustable automatic wire feeding device provided by this utility model has a detachable wire pressing wheel structure, which can be replaced in a timely and convenient manner after wear without disassembling the entire wire feeding structure. The wire feeding wheel opposite to the wire pressing wheel can be adjusted within a small range, thereby controlling the distance between the wire feeding wheel and the wire pressing wheel and realizing the adjustment of the tightness of the welding wire.

[0024] 3. The adjustable automatic wire feeding device provided by this utility model allows the welding wire to pass through the wire guide after being drawn out from the wire feeding spool. The wire guide can adapt to welding wires of different angles and smoothly introduce the welding wire into the wire feeding structure, which facilitates subsequent wire guiding operations.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0035] An adjustable automatic yarn feeding device, such as Figure 1 and Figure 2 As shown, the device includes a wire feeder frame 1, a main drive unit 2, a wire feeding structure 3, and a wire feeding reel 9. The main drive unit 2 is installed inside the wire feeder frame 1 and drives the wire feeding structure 3 to move. The wire feeding structure 3 is installed on the front side of the wire feeder frame 1. The wire feeding reel 9 is rotatably mounted on the top left end of the wire feeder frame 1, and both it and the wire feeding structure 3 are located on the front side. A wire guide 10 is also provided between the wire feeding structure 3 and the wire feeding reel 9. The welding wire is led out from the wire feeding reel 9 and fed through the wire feeding structure 3. The main drive unit 2 controls the wire feeding structure 3 to realize the wire feeding movement. During the wire feeding process, the welding wire passes through two sets of pressure rollers 4 and wire feeding rollers 5. A support 8 is provided between the two sets of pressure rollers 4 to prevent the middle of the welding wire from collapsing due to excessive stroke during the wire feeding process.

[0036] The wire feeding structure 3 includes two horizontally parallel pressing rollers 4, two horizontally parallel feeding rollers 5, a drive structure 6, a wire feeding base plate 7, and a support member 8. The pressing rollers 4, feeding rollers 5, drive structure 6, and support member 8 are all mounted on the wire feeding base plate 7. The pressing rollers 4 and feeding rollers 5 are arranged vertically side-by-side, with the pressing rollers 4 positioned above the feeding rollers 5. The drive structure 6 includes a main drive gear 61 coaxially connected to the main drive member 2 and two driven gears 62 coaxially arranged with the two feeding rollers 5 respectively. Both driven gears 62 mesh with the main drive gear 61 and are positioned opposite to it. The support member 8 is positioned at both ends corresponding to the gap between the pressing rollers 4 and feeding rollers 5 and is located between the two sets of pressing rollers 4 and feeding rollers 5. The pressing rollers 4 also have coaxial pressing gears, which mesh with the corresponding driven gears 62 below them for transmission. An outer cover 76 is also snapped onto the wire feeding base plate 7. The outer cover 76 can protect the structure on the wire feeding base plate 7 and block dust, so as to prevent the welding wire from being covered with dust during the wire feeding process and affecting the subsequent welding quality. On the other hand, the outer cover 76 can also be used to lock the clamping handle 74 to ensure the stability of the wire pressing wheel 4.

[0037] like Figure 1 and Figure 2 As shown, the wire guide 10 includes two arc-shaped wire guide blocks 101 arranged vertically opposite each other. The wire guide blocks 101 are rotatably connected to the wire feeder frame 1. Rotating blocks 1011 extend from the middle of the upper and lower sides of the two wire guide blocks 101 that are far apart from each other and are rotatably connected to the wire feeder frame 1. Two wire guide springs 1012 are also provided on the side of the two wire guide blocks 101 that are far apart from each other. The two wire guide springs 1012 are perpendicular to the side of the wire guide blocks 101. One end of the wire guide spring 1012 is fixed to the side of the wire guide block 101, and the other end is fixed to the wire feeder frame 1. The wire guide springs 1012 are arranged on the left and right sides of the rotating block 1011. The left wire guide spring 1012 is a tension spring, and the right wire guide spring 1012 is a pull spring. The wire guide blocks 101 and the wire guide springs 1012 can accommodate welding wires entering the wire feeder structure 3 at different angles, and the reaction force of the wire guide springs 1012 makes the welding wires smoothly fed into the wire feeder structure 3.

[0038] like Figure 3 and Figure 5 As shown, the drive structure 6 also includes a wire feeding shaft 63. The wire feeding wheel 5 and the driven gear 62 are both mounted on the wire feeding shaft 63. A locking nut 631 and a locking bolt 632 are respectively provided at both ends of the wire feeding shaft 63. The locking bolt 632 passes through the wire feeding shaft 63 and is threadedly connected to the locking nut 631. The locking bolt 632 and the locking nut 631 limit the positions of the wire feeding wheel 5 and the driven gear 62 on the wire feeding shaft 63, ensuring close contact between the two and preventing back-and-forth displacement during rotation, which would affect the wire feeding effect.

[0039] Two parallel positioning pins 621 extend from the drive gear 62 near the wire feeding wheel 5, and two through positioning holes 51 are correspondingly provided on the wire feeding wheel 5. The wire feeding wheel 5, mounted on the wire feeding shaft 63, and the drive gear 62 rotate synchronously due to the positioning pins 621 and the positioning holes 51.

[0040] like Figure 3 and Figure 5 As shown, an adjusting component 633 is also installed on the wire feeding shaft 63. The adjusting component 633 includes an adjusting seat 6331, an adjusting shaft 6332, and a control seat 6333. The wire feeding shaft 63 passes through the adjusting seat 6331 and is rotatably mounted at its end within the adjusting seat 6331. The adjusting seat 6331 is vertically slidably mounted within the wire feeding base plate 7. An adjusting groove 77 is provided on the wire feeding base plate 7 corresponding to the adjusting seat 6331. The axis of the adjusting shaft 6332 is perpendicular to the axis of the wire feeding shaft 63 and is set along the sliding direction of the adjusting seat 6331. The adjusting shaft 6332 is also threadedly connected to the control seat 6333. The control seat 6333 extends and is located on the side of the adjusting seat 6331 away from the main drive gear 61. Both ends of the adjusting shaft 6332 are also rotatably mounted on the wire feeding base plate 7. An adjusting handle 63321 extends from the bottom end of the adjusting shaft 6332. Rotating the adjusting handle 63321 controls the adjusting shaft 6332 to rotate, causing the control seat 6333 to slide. The adjusting seat 6331, which is integrated with the control seat 6333, slides up and down in the adjusting groove 77, thereby realizing the up and down movement of the wire feeding shaft 63 within the adjusting seat 6331. During this process, the driven gear 62 is always engaged with the main drive gear 61. Therefore, the range of up and down sliding of the adjusting seat 6331 is relatively small, and the tension between the pressure roller 4 and the wire feeding roller 5 can only be adjusted within a small range. To expand the adjustment range, the adjusting seat 6331 and the adjusting shaft 6332 can be slid along the line connecting the centers of the main drive gear 61 and the driven gear 62, thereby expanding the range of adjustment of the meshing backlash and further adjusting the tension.

[0041] like Figure 3 , Figure 4 and Figure 6As shown, two horizontally parallel wire pressing brackets 71 are also provided on the wire feeding base plate 7. The wire pressing brackets 71 are rotatably connected to the wire feeding base plate 7, and the ends of the two wire pressing brackets 71 that are close to each other are provided with hinge shafts, that is, the right side of the left wire pressing bracket 71 and the left side of the right wire pressing bracket 71 are provided with hinge shafts. The axis of the hinge shaft is parallel to the axis of the main drive gear 61. The wire pressing brackets 71 are correspondingly provided with the wire pressing wheel 4. The wire pressing wheel 4 is rotatably installed in the wire pressing bracket 71. The wire pressing bracket 71 is provided with a mounting pin 711 for fixing the wire pressing wheel 4. The mounting pin 711 passes through the wire pressing bracket 71 and the wire pressing wheel 4 and is engaged with the wire feeding base plate 7. The mounting pin 711 is provided with a locking groove 7111 on the side of the mounting pin 711 close to the wire feeding base plate 7. A locking ring 7112 is provided on the wire pressing bracket 71 corresponding to the locking groove 7111. The pressure roller 4 is installed in the pressure bracket 71 and fixed by the mounting pin 711. The pressure bracket 71 with the pressure roller 4 is then fixed to the wire feeding base plate 7 by the clamping handle 74. When disassembly is required, the operating handle 741 is rotated to disengage from the movable groove 721, and then the pressure bracket 71 is rotated upward. Finally, the mounting pin 711 is removed to take out the pressure roller 4.

[0042] like Figure 3 and Figure 6 As shown, the wire feeding base plate 7 also has movable seats 73 extending from both ends relative to the wire pressing bracket 71. A clamping handle 74 is rotatably mounted on the movable seat 73. The clamping handle 74 includes an operating handle 741, a movable handle 742, and a movable shaft 743. One end of the movable shaft 743 is fixedly set to the operating handle 741, and the other end of the movable shaft 743 is rotatably connected to the wire feeding base plate 7. The rotation axis of the movable shaft 743 is set along the length direction of the wire feeding base plate 7. The movable handle 742 is slidably set inside the operating handle 741 and sleeved outside the movable shaft 743. A handle spring 744 is also sleeved on the movable shaft 743. The handle spring 744 is installed inside the movable handle 742. The two ends of the handle spring 744 are respectively connected to the inner top wall of the operating handle 741 and the inner bottom wall of the movable handle 742. Two wire-feeding brackets 71, located at opposite ends, have clamping seats 72 extending from the clamping handle 74. Each clamping seat 72 has a forward-opening movable groove 721, and its top has a V-shaped clamping groove 722 that mates with the bottom of the movable handle 742. The movable seat 73 allows the movable shaft 743 to rotate and also provides limiting support for the wire-feeding bracket. The engagement of the movable handle 742 with the clamping groove 722 locks the wire-feeding roller 4 after installation.

[0043] like Figure 3 , Figure 4 and Figure 5As shown, the wire feeding base plate 7 extends from the side near the wire feeding frame 1 with multiple mounting posts 75. The wire feeding frame 1 has an arc-shaped mounting groove 11 corresponding to the mounting posts 75. A coaxial mounting washer 751 is also fitted on the mounting post 75. The mounting washer 751 is positioned between the wire feeding base plate 7 and the wire feeding frame 1. A mounting nut 752 is also threaded onto the mounting post 75. The mounting nut 752 is positioned on the side of the wire feeding frame 1 away from the wire feeding base plate 7. The mounting posts 75 and the mounting groove 11 cooperate to fix the wire feeding base plate 7 on the wire feeding frame 1. Due to the arc-shaped design of the mounting groove 11, the wire feeding base plate 7 can be deflected at a certain angle on the wire feeding frame 1, thereby better adapting to the angle at which the wire feeding spool 9 outputs the wire.

[0044] like Figure 3 and Figure 4 As shown, the support member 8 includes a support tube 81 and a support base 82. The axis of the support tube 81 is arranged along the length of the wire feeding base plate 7. A wire feeding hole 811 is opened through the middle of the support tube 81. Relief grooves are provided at both ends of the support tube 81 corresponding to the wire pressing wheel 4 and the wire feeding wheel 5. The support tube 81 is embedded in the support base 82, and the support base 82 is fixed to the wire feeding base plate 7 by screws. During the feeding process, the welding wire also passes through the support member 8. On the one hand, it can rub against the tube wall of the support tube 81 to reduce surface dust. On the other hand, it can prevent long sections of the wire from being suspended in the air during the feeding process, which would cause the welding wire to loosen and affect the accuracy of subsequent wire feeding.

[0045] The working principle and usage of this adjustable automatic wire feeding device are as follows: The wire pressure wheel 4 is installed in the wire pressure bracket 71 and fixed by the mounting pin 711. The wire pressure bracket 71 with the wire pressure wheel 4 is then fixed to the wire feeding base plate 7 by the clamping handle 74. The distance between the wire pressure wheel 4 and the wire feeding wheel 5 is finely adjusted according to the welding wire and welding requirements to control the wire feeding tightness. Finally, the welding wire is led out by the wire feeding tray 9 and fed through the wire feeding structure 3. The main drive component 2 controls the wire feeding structure 3 to realize the wire feeding movement. During the wire feeding process, the welding wire also passes through the support component 8.
