Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and more specifically to a wire feeding device for a welding machine. Background Art

[0002] Wire feeding involves feeding the welding wire into the welding area at a steady speed and position using a specialized wire feeder to ensure continuity and quality. During this process, the wire feeder precisely controls the wire's feed rate, speed, and direction, maintaining the proper distance and angle from the welding arc or heat source to achieve precise fill and connection of the weld. Wire feeding requires not only continuous and smooth wire delivery but also protection from breakage, tangling, or deviation from the intended path during welding, ensuring consistent and reliable welding quality.

[0003] In the prior art, welding machine wire feeders generally use traditional methods for replacing wire spools, which are often cumbersome and time-consuming. Specifically, after using the wire on the wire spool, the operator must manually remove multiple fixing components, such as screws and clips, to remove the wire spool from the connecting roller of the wire feeder. When installing a new wire spool on the connecting roller, multiple components must also be manually adjusted to ensure that the wire spool is securely attached to the equipment. This increases downtime during production and reduces overall production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] See also Figure 1-Figure 5 , a welding machine wire feeding device, comprising:

[0029] A mounting plate 1 is provided, wherein the outer surface of one side of the mounting plate 1 is rotatably connected to a connecting roller 2, a limit plate 7 is fixedly sleeved on the connecting roller 2, two fixing plates 8 are fixedly connected between the inner walls of the connecting roller 2, a bidirectional threaded rod 9 is rotatably connected between the two fixing plates 8, two transmission blocks 10 are threadedly connected to the bidirectional threaded rod 9, and two L-shaped clamping plates 11 are slidably passed through the inner wall of the connecting roller 2, and the outer surface of one side of the two L-shaped clamping plates 11 are rotatably connected to two transmission rods 12, and each two transmission rods 12 are rotatably connected to the corresponding transmission block 10; and

[0030] The feed frame 5 is fixedly connected to the outer surface of one side of the mounting plate 1 , and two groups of feed rollers 16 are rotatably connected between the inner walls on both sides of the feed frame 5 , and each group of feed rollers 16 is provided with three.

[0031] The wire reel 3 is a common tool for winding the welding wire. The wire reel 3 is slidably mounted on the connecting roller 2. The welding wire on the wire reel 3 passes between the upper and lower sets of feeding rollers 16. The direction of each set of feeding rollers 16 is the same, but the two sets of feeding rollers 16 have opposite directions. By controlling the rotation of the connecting roller 2, the wire reel 3 is driven to rotate slowly and the welding wire is slowly released. At the same time, the two sets of feeding rollers 16 drive the welding wire toward the processing position through friction to realize the feeding function of the welding wire. During the welding wire feeding operation, the wire reel 3 is located between the limit plate 7 and the two L-shaped clamping plates 11, so that the wire reel 3 will not be offset and is installed on the connecting roller 2. When the welding wire on the wire reel 3 is used up, the bidirectional screw is controlled to rotate. The rotation of the threaded rod 9 can drive the two transmission blocks 10 to move relatively away from each other, and the four transmission rods 12 drive the two L-shaped clamps 11 to move relatively close to each other, so that the two L-shaped clamps 11 are retracted into the interior of the connecting roller 2, so that the welding wire reel 3 can be easily removed from the connecting roller 2, and then the new welding wire reel 3 is put on the connecting roller 2 and fits with the limit plate 7, and then the two-way threaded rod 9 is controlled to rotate to drive the two transmission blocks 10 to move relatively close to each other, and the four transmission rods 12 drive the two L-shaped clamps 11 to move relatively away from each other, so that the two L-shaped clamps 11 are fit with the sides of the welding wire reel 3, completing the rapid replacement of the welding wire reel 3, greatly shortening the time required to replace the welding wire, reducing downtime, and greatly improving production efficiency.

[0032] Specifically, an outer surface of one side of the feed frame 5 is fixedly connected to a mounting frame 18, and two sets of transmission wheels 17 are rotatably connected between the mounting frame 18 and the feed frame 5, and each set of transmission wheels 17 is provided with two. Two feed motors 19 are fixedly installed on the outer surface of one side of the mounting frame 18, and the output end of each feed motor 19 is fixedly connected to the corresponding transmission wheel 17.

[0033] In this embodiment, each transmission wheel 17 is fixedly connected to the corresponding feed roller 16, and the upper and lower sets of transmission wheels 17 are connected by a transmission belt. By starting the two feed motors 19, the two sets of transmission wheels 17 can be driven to rotate in opposite directions, thereby driving the upper two feed rollers 16 and the lower two feed rollers 16 to rotate in opposite directions.

[0034] Specifically, a guide tube 4 is fixedly connected to the outer surface of one side of the mounting plate 1 .

[0035] In this embodiment, the guide tube 4 is used to guide the welding wire into between the upper and lower groups of feed rollers 16.

[0036] Specifically, a reduction motor 6 is fixedly mounted on the rear outer surface of the mounting plate 1 , and an output end of the reduction motor 6 is fixedly connected to the connecting roller 2 .

[0037] In this embodiment, the connecting roller 2 can be driven to rotate slowly by controlling the reduction motor 6 to start.

[0038] Specifically, a driving motor 13 is fixedly mounted on the inner wall of one side of the connecting roller 2 , and an output end of the driving motor 13 is fixedly connected to the bidirectional threaded rod 9 .

[0039] In this embodiment, the bidirectional threaded rod 9 can be driven to rotate by controlling the driving motor 13 to start.

[0040] Specifically, a cross bar 14 is fixedly connected between the two fixed plates 8, and the two transmission blocks 10 are slidably mounted on the cross bar 14. Two limit rods 15 are fixedly connected between the inner walls of the connecting rollers 2, and each L-shaped clamping plate 11 is slidably mounted on the two limit rods 15.

[0041] In this embodiment, the two limiting rods 15 keep the two L-shaped clamping plates 11 stable during the relative movement, and the cross bar 14 keeps the two transmission blocks 10 stable during the relative movement.

[0042] Working principle: By controlling the reduction motor 6 and the two feeding motors 19 to start, the reduction motor 6 drives the connecting roller 2 to rotate, drives the wire reel 3 to rotate slowly, and slowly releases the welding wire. The two feeding motors 19 drive the corresponding two transmission wheels 17 to rotate in the opposite direction, thereby driving the two upper feeding rollers 16 and the two lower feeding rollers 16 to rotate in the opposite direction. The two sets of feeding rollers 16 drive the welding wire toward the processing position through friction, thereby realizing the feeding function of the welding wire. When the welding wire on the wire reel 3 is used up, by controlling the drive motor 13 to start, the bidirectional threaded rod 9 is controlled and driven to rotate, which can drive the two transmission blocks 10 to move relatively away from each other, and drive the two L-shaped splints 11 to move relatively close to each other through the four transmission rods 12, so that the two L-shaped splints 11 are retracted into the inside of the connecting roller 2, so that it can be very light Loosely remove the wire reel 3 from the connecting roller 2, then put the new wire reel 3 on the connecting roller 2 and fit it with the limit plate 7, and then control the two-way threaded rod 9 to rotate in the opposite direction, drive the two transmission blocks 10 to move relatively close, and drive the two L-shaped clamps 11 to move relatively away from each other through the four transmission rods 12, so that the two L-shaped clamps 11 fit the sides of the wire reel 3, completing the rapid replacement of the wire reel 3, greatly shortening the time required for replacing the welding wire, reducing downtime, and greatly improving production efficiency. The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention no longer explains the control method and wiring layout in detail.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
