Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum alloy welding wire processing equipment, specifically relating to an aluminum alloy welding wire feeding device with dynamic tension balancing function. Background Technology

[0002] Aluminum alloy welding wire often requires processing during use, necessitating the feeding of a whole roll of wire for continuous processing. Existing patent CN222387583U discloses a shaping extrusion device for metal wire carrier tape, including a carrier tape with a semi-circular cross-section and an embedding groove at its top. The device includes a cooling water tank, an extrusion seat, and a winding mechanism. A guide roller is rotatably connected inside the cooling water tank. A semi-circular shaping groove is formed inside the extrusion seat, with a shaping protrusion fixed to its top. The winding mechanism includes a frame and a winding roller. Existing feeding devices often require the wire to be fed through the coordinated action of the winding roller, guide roller, first suspension roller, and second suspension roller. Tension is adjusted by the first and second suspension rollers during operation. However, due to the limited winding distance of the wire, the effect of adjusting tension using the traditionally moving first and second suspension rollers is poor, resulting in a loose wire during transport and low processing accuracy. Therefore, it is necessary to design an aluminum alloy welding wire feeding device with dynamic tension balancing function to overcome the above difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an aluminum alloy welding wire feeding device with dynamic tension balancing function. This invention feeds the wire by setting a feeding device on a moving platform, guides and straightens the wire by guiding the wire feeding assembly, and simultaneously tensions the wire by multiple guides on an adjustable tensioning assembly, resulting in good and reliable tensioning effect.

[0004] The objective of this invention is achieved through the following technical solution: an aluminum alloy welding wire feeding device with dynamic tension balancing function, comprising a moving platform, wherein a feeding device and a wire feeding guide assembly are provided on the moving platform, and an adjustable tensioning assembly is provided between the feeding device and the wire feeding guide assembly; the wire feeding guide assembly includes a mounting base, wherein a fixed lead wheel is rotatably connected to the mounting base; a sliding member that can move relative to the fixed lead wheel is also provided on the mounting base, wherein a movable lead wheel is provided on the sliding member; the adjustable tensioning assembly includes a main support, wherein a plurality of guide members are arranged in a ring around the main support; a rotating handle that is rotatably connected to the main support is provided inside the main support, and a connecting rod is provided between the rotating handle and the guide members; when the rotating handle is rotated, each guide member can synchronously extend and retract relative to the main support.

[0005] Preferably, the feeding device includes a feeding bracket, a feeding roller and a first motor; the bottom of the feeding device is provided with a feeding roller that is rotatably connected thereto, and the first motor is connected to the feeding roller. When the first motor is working, it drives the feeding roller to rotate relative to the feeding bracket.

[0006] Preferably, the feeding device is further provided with several guide rollers that are rotatably connected to it; each guide roller is arranged side by side vertically and is located close to the guide member.

[0007] The feeding device has aluminum alloy welding wire wound on its feeding roller. The aluminum alloy welding wire passes through the wire roller and is then wound onto the guide member located at the top. The aluminum alloy welding wire is wound around the guide member twice along the direction of the rotating main shaft and then passed through the wire feeding assembly. When the first motor is working, it drives the feeding roller to rotate, so that the feeding can be continuously fed. Then the wire feeding assembly can straighten the aluminum alloy welding wire and transport it to the next process. Since the aluminum alloy welding wire is tensioned by the adjustable tensioning assembly, the straightening effect of the aluminum alloy welding wire is better.

[0008] Preferably, the wire feeding assembly further includes a knob, a screw, a feed component, and a discharge component; the mounting base is provided with a sliding component slidably connected thereto, and the screw is rotatably connected to the mounting base; a knob is fixedly installed at the top end of the screw, and the screw is threadedly connected to the sliding component; the sliding component is provided with several movable wire guide wheels rotatably connected thereto, and the movable wire guide wheels are detachably installed on the sliding component; the mounting base is provided with several mounting discs rotatably connected thereto, and fixed wire guide wheels are detachably installed on the mounting discs; a second motor for driving the mounting discs to rotate is provided on the back of the mounting base.

[0010] Preferably, the mounting base has a feeding component and a discharging component at its left and right ends, respectively. The feeding component is positioned close to the adjustable tensioning component, and the discharging component is positioned opposite the feeding component. An intermediate guide wire is provided between the feeding component and the discharging component, and the feeding component, the discharging component, and the intermediate guide wire are all arranged on the same axis. The mounting base has a pair of guide protrusions, and the sliding component has a pair of limiting grooves. The guide protrusions are disposed within the limiting grooves, and the outer contour of the guide protrusions matches the outer contour of the limiting grooves.

[0011] When the aluminum alloy welding wire emerges from the guide of the adjustable tension assembly, it first passes through the feed component; then the aluminum alloy welding wire is threaded between the fixed lead wheel and the movable lead wheel, and finally exits from the discharge component; according to the wire diameter, the movable lead wheel adapted to the aluminum alloy welding wire is installed on the sliding component, and the fixed lead wheel adapted to the aluminum alloy welding wire is installed on the mounting plate; the fixed lead wheel and the mounting plate rotate synchronously, and the movable lead wheel can rotate relative to the sliding component; then, by turning the knob to drive the screw to rotate, the sliding component can engage and move relative to the mounting base; by turning the knob, the aluminum alloy welding wire is clamped between the fixed lead wheel and the movable lead wheel; then, the second motor works to drive the mounting plate to rotate, and the shaft of the mounting plate is equipped with gears, so all the mounting plates will rotate synchronously, thereby feeding the aluminum alloy welding wire from the mounting base to the next process; since the aluminum alloy welding wire is wound multiple times on the guide of the adjustable tension assembly, the aluminum alloy welding wire can always be kept taut. The speeds of the first and second motors are pre-set at the factory to ensure that the aluminum alloy welding wire on the feeding device does not scatter.

[0012] Preferably, the adjustable tensioning assembly further includes a connecting bushing and a sliding bushing; the connecting bushing is fixedly connected to the main support, and a rotating spindle is fixedly mounted on the rotating handle; the rotating spindle passes through the connecting bushing and is rotatably connected to the main support; a sliding bushing is provided between the connecting bushing and the rotating handle; the sliding bushing is mounted on the rotating spindle and is threadedly connected to the rotating spindle; a connecting rod is provided between the sliding bushing and the guide, and the guide can extend and retract radially relative to the connecting bushing; a locking assembly is provided between the rotating spindle and the main support.

[0013] Preferably, the connecting bushing is provided with a plurality of guide channels arranged in a ring around it, the guide channels being perpendicular to the connecting bushing; a guide member is slidably installed in the guide channel, the guide member including a guide shaft and a pair of blocking members; the blocking members are located at both ends of the guide shaft, one end of the connecting rod is hinged to the guide shaft, and the other end of the connecting rod is hinged to the sliding bushing; when the rotating handle is rotated, each of the guide members extends and retracts relative to the connecting bushing.

[0014] Preferably, the locking assembly includes a brake band, a pair of bolts, and a pair of elastic elements; the rotating spindle has an annular groove for mounting the brake band, and the brake band is wound around the annular groove; adapters are fixedly mounted at both ends of the brake band, and the bolts are inserted into the main support and threadedly connected to the adapters; a bolt is slidably mounted on the top of the main support, and the end of the bolt is threadedly connected to the adapter; a washer and an elastic element are mounted on the bolt, and the washer is fitted against the upper end face of the main support; the elastic element is disposed between the protrusion of the bolt and the washer; the elastic element is a compression spring.

[0015] Before the wire feeding assembly operates, the tension of the aluminum alloy welding wire is pre-adjusted using the adjustable tensioning assembly. By rotating the handle, the main shaft rotates relative to the main support, causing the sliding sleeve to engage and move relative to the main shaft. The movement of the sliding sleeve drives the connecting rod, which in turn causes the guide members to extend and retract relative to the guide channel. After the guide members move, the distance between each guide member and the main shaft changes synchronously, tensioning the aluminum alloy welding wire according to its diameter. Once tensioned, the main shaft is locked using a locking assembly to prevent rotation relative to the main support. Rotating the bolt compresses the elastic element, adjusting the friction between the brake band and the main shaft, thus locking the main shaft. Even after prolonged operation of the adjustable tensioning assembly, the main shaft may still tend to rotate, but the brake band prevents large-scale rotation, thus minimizing changes in the tension of the aluminum alloy welding wire.

[0016] Compared with the prior art, the present invention has the following advantages: 1. By rotating the handle, the extension and retraction of each guide relative to the main support can be controlled simultaneously. The aluminum alloy welding wire is supported by the guide, and the force on the aluminum alloy welding wire is more uniform, resulting in better tension. 2. The rotating spindle is locked by the locking component, preventing the rotating spindle from rotating during the feeding process, so that the aluminum alloy welding wire is always in a taut state, resulting in good tension. 3. The aluminum alloy welding wire is straightened and fed out by the wire feeding component. The distance between the movable lead wheel and the fixed lead wheel can be adjusted to adapt to the transportation of aluminum alloy welding wires of different diameters, resulting in better versatility.

The feeding component 37 is located near the adjustable tensioning component 4, and the discharging component 38 is located opposite the feeding component 37.

The guide protrusions 313 are located in the limiting grooves 314, and the outer contour of the guide protrusions 313 is adapted to the outer contour of the limiting grooves 314.

[0028] The adjustable tensioning assembly 4 also includes a connecting bushing 45 and a sliding bushing 46; the connecting bushing 45 is fixedly connected to the main support 41, and a rotating spindle 47 is fixedly mounted on the rotating handle 43; the rotating spindle 47 passes through the connecting bushing 45 and is rotatably connected to the main support 41; a sliding bushing 46 is provided between the connecting bushing 45 and the rotating handle 43; the sliding bushing 46 is mounted on the rotating spindle 47 and is threadedly connected to the rotating spindle 47; a connecting rod 44 is provided between the sliding bushing 46 and the guide 42, and the guide 42 can extend and retract radially relative to the connecting bushing 45; a locking assembly 5 is provided between the rotating spindle 47 and the main support 41. The connecting bushing 45 is provided with a plurality of guide channels 48 arranged in a ring around it, and the guide channels 48 are arranged perpendicularly to the connecting bushing 45. A guide member 42 is slidably installed in the guide channel 48. The guide member 42 includes a guide shaft 421 and a pair of blocking members 422. The blocking members 422 are arranged at both ends of the guide shaft 421. One end of the connecting rod 44 is hinged to the guide shaft 421, and the other end of the connecting rod 44 is hinged to the sliding bushing 46. When the rotating handle 43 is rotated, each guide member 42 extends and retracts relative to the connecting bushing 45. The locking assembly 5 includes a brake band 51, a pair of bolts 52, and a pair of elastic elements 53. The rotating spindle 47 has an annular groove 6 for mounting the brake band 51, which is wound within the groove. Two adapters 54 are fixedly mounted at the two ends of the brake band 51. The bolts 52 are inserted into the main support 41 and threadedly connected to the adapters 54. A bolt 52 is slidably mounted on the top of the main support 41, and its end is threadedly connected to the adapter 54. A washer 55 and an elastic element 53 are mounted on the bolt 52, with the washer 55 fitting snugly against the upper surface of the main support 41. The elastic element 53 is positioned between the protrusion of the bolt 52 and the washer 55; the elastic element 53 is a compression spring.

[0029] The specific operation process of this embodiment is as follows: the feeding roller 22 of the feeding device 2 is wound with aluminum alloy welding wire. The aluminum alloy welding wire passes through the wire roller 24 and is then wound onto the guide member 42 located at the top. The aluminum alloy welding wire is wound around the guide member 42 twice along the direction of the rotating main shaft 47 and then passed through the guide wire feeding assembly 3. When the first motor 23 is working, it drives the feeding roller 22 to rotate, so that the feeding can be continuous. Then the guide wire feeding assembly 3 can straighten the aluminum alloy welding wire and transport it to the next process. Since the aluminum alloy welding wire is tensioned by the adjustable tensioning assembly 4, the straightening effect of the aluminum alloy welding wire is better. Before the wire feeding assembly 3 operates, the tension of the aluminum alloy welding wire is pre-adjusted using the adjustable tensioning assembly 4. By rotating the rotating handle 43, the rotating spindle 47 rotates relative to the main support 41, and the sliding bushing 46 engages and moves relative to the rotating spindle 47. When the sliding bushing 46 moves, it drives the connecting rod 44 to move, and the connecting rod 44 drives the guide member 42 to extend and retract relative to the guide channel 48. After the guide member 42 moves, the distance between each guide member 42 and the rotating spindle 47 changes synchronously, thus tensioning the aluminum alloy welding wire according to the different wire diameters. When the aluminum alloy welding wire is tensioned, the rotating spindle 47 is locked by the locking assembly 5 to prevent the rotating spindle 47 from rotating relative to the main support 41. By rotating the bolt 52, the bolt 52 compresses the elastic member 53, and the friction between the brake band 51 and the rotating spindle 47 can be adjusted accordingly, thereby locking the rotating spindle 47 by the brake band 51. When the adjustable tensioning assembly 4 has been working for a long time, the rotating spindle 47 tends to rotate, but the brake band 51 holds the rotating spindle 47 in place, thus preventing the rotating spindle 47 from rotating in a large range. In this way, the tension of the aluminum alloy welding wire will not change significantly.

[0030] When the aluminum alloy welding wire passes through the guide 42 of the adjustable tension assembly, it first passes through the feed member 37; then the aluminum alloy welding wire is inserted between the fixed lead wire wheel 32 and the movable lead wire wheel 34, and finally passes through the discharge member 38; according to the wire diameter of the aluminum alloy welding wire, the movable lead wire wheel 34 adapted to the aluminum alloy welding wire is installed on the sliding member 33, and the fixed lead wire wheel 32 adapted to the aluminum alloy welding wire is installed on the mounting plate 39; the fixed lead wire wheel 32 rotates synchronously with the mounting plate 39, and the movable lead wire wheel 34 can rotate relative to the sliding member 33; then the screw 3 is driven by the knob 35. When the knob 35 is rotated, the sliding member 33 can engage and move relative to the mounting base 31. By rotating the knob 35, the aluminum alloy welding wire is clamped between the fixed lead wheel 32 and the movable lead wheel 34. Then, the second motor 310 drives the mounting plate 39 to rotate. The shaft of the mounting plate 39 is equipped with a gear 311, so all the mounting plates 39 will rotate synchronously, thereby feeding the aluminum alloy welding wire from the mounting base 31 to the next process. Since the aluminum alloy welding wire is wound multiple times on the guide member 42 of the adjustable tensioning component 4, the aluminum alloy welding wire can always be kept taut. Here, the speed of the first motor 23 and the second motor 310 has been set at the factory to ensure that the aluminum alloy welding wire on the feeding device 2 will not unravel.
