Description

Technical Field

[0001] This utility model relates to the field of buffer technology for wire feeders, specifically a wire feeder with buffer. Background Technology

[0002] A wire feeder is a welding auxiliary device controlled by a microcomputer, mainly used in welding processes such as argon arc welding, laser welding, and plasma welding. Its core function is to replace manual operation and automatically feed the welding wire into the welding gun, thereby improving welding efficiency and consistency.

[0003] Existing wire feeding equipment has several main problems during use. When the wire is subjected to fluctuations in external tension or instantaneous changes in feeding speed, the wire is prone to breakage due to excessive tension or slack and accumulation due to insufficient tension, which poses certain safety hazards and reduces the efficiency of wire feeding. Furthermore, existing wire feeding equipment lacks an adjustable buffer mechanism, making it unable to quickly adapt to the buffering requirements under different working conditions, thus reducing the applicability of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a buffered wire feeder with the advantages of a buffer driven wheel that can offset and absorb tension and is easy to adapt to buffering requirements under different working conditions, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a buffered wire feeder, comprising a housing, a motor fixedly mounted on the outer side of the housing, a drive wheel fixedly mounted on the power output shaft of the motor, a fixed rod fixedly mounted on the inner top of the housing, a buffer groove formed at the bottom of the fixed rod, a positioning rod fixedly mounted on the inner wall of the buffer groove, a buffer rod slidably connected to the inner wall of the buffer groove and the outer edge of the positioning rod, a positioning groove formed at the top of the buffer rod, a sliding groove formed on the inner wall of the buffer groove, a through groove formed through the inner wall of the sliding groove, a locking groove formed on the inner wall of the through groove, a movable plate slidably connected to the inner wall of the through groove, a buffer spring provided between the bottom of the movable plate and the top of the buffer rod, storage grooves formed on both sides of the movable plate, limit grooves formed on the upper and lower sides of the storage groove, a second spring fixedly mounted on the inner wall of the storage groove, a pressing plate fixedly mounted on the extension end of the second spring, limit blocks fixedly mounted on the upper and lower sides of the pressing plate, and a locking block and a pressing block fixedly mounted on the outer side of the pressing plate.

[0008] As a preferred technical solution of this utility model: the shape of the card block is adapted to the shape of the card slot, and the card block and the card slot are slidably connected.

[0009] As a preferred technical solution of this utility model: the movable plate is slidably connected to the outer edge of the positioning rod, the number of the slots is several, and the outer side of the housing is provided with an operation port.

[0010] As a preferred technical solution of this utility model: the buffer rod is L-shaped, and a buffer driven wheel is fixedly installed at the bottom of the buffer rod, and a remote control is externally mounted on the device, and the motor is electrically connected to the remote control.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This buffered wire feeder, through the combined use of buffer rods and buffer springs, allows the wire to be subjected to external tension fluctuations or instantaneous changes in the wire feeding speed. When the wire tension increases, it affects the buffer driven wheel. At this time, the buffer driven wheel, affected by the wire, drives both buffer rods to move upwards simultaneously, causing the buffer springs to deform and contract, thereby offsetting the tension and preventing the wire from breaking directly. The buffer springs can also absorb some tension fluctuations. When the tension returns to normal, the restriction on the buffer springs disappears, allowing the buffer springs to drive the buffer rods and buffer driven wheel to adjust downwards slightly to return to their original positions, maintaining a stable clamping force and preventing slippage.

[0012] 2. This buffered wire feeder, through the cooperation of the locking block and the locking slot, allows the pressing block to be pressed, causing the pressing plate to slide towards the inner wall of the receiving slot, and compressing the second spring to deform and contract, thus separating the locking block from the locking slot. At this time, the sliding plate can be manually pressed down, causing the sliding plate to compress the buffer spring to deform, reducing the movement gap of the buffer rod, thereby adjusting the buffering force of the buffer driven wheel, so as to quickly adapt to the buffering needs under different working conditions.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 A buffered wire feeder includes a housing 1. A motor 2 is fixedly mounted on the outer side of the housing 1. A drive wheel 4 is fixedly mounted on the power output shaft of the motor 2. A fixing rod 5 is fixedly mounted on the inner top of the housing 1. A buffer groove 8 is formed at the bottom of the fixing rod 5. A positioning rod 9 is fixedly mounted on the inner wall of the buffer groove 8. A buffer rod 6 is slidably connected to the inner wall of the buffer groove 8 and the outer edge of the positioning rod 9. A positioning groove 11 is formed at the top of the buffer rod 6. A sliding groove 12 is formed on the inner wall of the buffer groove 8. A through groove 13 extends through the inner wall of the sliding groove 12. The inner wall is provided with a slot 14, and a movable plate 15 is slidably connected to the inner wall of the through groove 13. A buffer spring 10 is provided between the bottom of the movable plate 15 and the top of the buffer rod 6. Storage slots 16 are provided on both sides of the movable plate 15. Limiting slots 17 are provided on the upper and lower sides of the storage slots 16. A second spring 18 is fixedly installed on the inner wall of the storage slots 16. A pressing plate 19 is fixedly installed on the extended end of the second spring 18. Limiting blocks 20 are fixedly installed on the upper and lower sides of the pressing plate 19. A locking block 21 and a pressing block 22 are fixedly installed on the outer side of the pressing plate 19.

[0017] In the above structure, the buffer rod 6 and the buffer spring 10 work together to prevent the yarn from being subjected to external tension fluctuations or sudden changes in the yarn feeding speed. When the yarn tension increases, it will affect the buffer driven wheel 7. At this time, the buffer driven wheel 7 is affected by the yarn, which drives the two buffer rods 6 to move upward at the same time, causing the buffer spring 10 to deform and contract, thereby offsetting the tension and preventing the yarn from breaking directly. The buffer spring 10 can also absorb some tension fluctuations. When the tension returns to normal, the restriction on the buffer spring 10 disappears, allowing the buffer spring 10 to drive the buffer rod 6 and the buffer driven wheel 7 to adjust downward slightly and return to their original positions, maintaining a stable clamping force and preventing slippage.

[0018] In a preferred embodiment: sliders 23 are fixedly installed on both sides of the buffer rod 6, the sliders 23 are slidably connected to the slide groove 12, and the positioning groove 11 is slidably connected to the positioning rod 9.

[0019] In the above structure, the sliding connection between the slider 23 and the slide groove 12, as well as the positioning groove 11 and the positioning rod 9, can limit the sliding of the buffer rod 6 and prevent the buffer rod 6 from being displaced.

[0020] In a preferred embodiment: the limiting block 20 and the limiting groove 17 are slidably connected, and the pressing plate 19 is slidably connected to the inner wall of the storage groove 16.

[0021] In the above structure, the sliding connection between the limiting block 20 and the limiting groove 17 allows the sliding of the pressing plate 19 to be limited during the pressing process by the pressing block 22.

[0022] In a preferred embodiment, the shape of the card block 21 is adapted to the shape of the card slot 14, and the card block 21 and the card slot 14 are slidably connected.

[0023] In the above structure, by using the cooperation of the locking block 21 and the locking slot 14, the pressing block 22 can be pressed to make the pressing block 22 drive the pressing plate 19 to slide towards the inner wall of the storage slot 16, and squeeze the spring 18 to deform and contract, so that the locking block 21 separates from the locking slot 14. At this time, the sliding moving plate 15 can be manually pressed down, so that the moving plate 15 squeezes the buffer spring 10 to deform, reducing the movement gap of the buffer rod 6, thereby adjusting the buffering force of the buffer driven wheel 7, so as to quickly adapt to the buffering needs under different working conditions.

[0024] In a preferred embodiment: the movable plate 15 is slidably connected to the outer edge of the positioning rod 9, the number of slots 14 is several, and the outer side of the housing 1 is provided with an operation port 3.

[0025] In the above structure, the moving plate 15 can be adjusted according to actual needs by setting several slots 14, thereby adapting to the buffering needs under different working conditions. Secondly, the operation port 3 makes it easy to press the pressing block 22 to adjust the position of the moving plate 15.

[0026] In a preferred embodiment: the buffer rod 6 is L-shaped, and a buffer driven wheel 7 is fixedly installed at the bottom of the buffer rod 6. The device is equipped with a remote control, and the motor 2 is electrically connected to the remote control.

[0027] In the above structure, the motor 2 can be controlled by an external remote control. By using the fixed installation between the buffer rod 6 and the buffer driven wheel 7, the buffer driven wheel 7 can be buffered by the buffer rod 6 after sensing the tension fluctuation of the yarn.

[0028] Working principle: When this device is needed, the buffer rods 6 and buffer springs 10 work together. When the yarn is subjected to external tension fluctuations or the yarn feeding speed changes instantaneously, the increased yarn tension will affect the buffer driven wheel 7. At this time, the buffer driven wheel 7, affected by the yarn, will drive both buffer rods 6 to move upwards simultaneously, causing the buffer spring 10 to deform and contract, thereby offsetting the tension and preventing the yarn from breaking directly. The buffer spring 10 can also absorb some tension fluctuations. When the tension returns to normal, the restriction on the buffer spring 10 disappears, allowing the buffer spring 10 to drive the buffer rods. 6 and the buffer driven wheel 7 are slightly adjusted downwards to return to their original positions, maintaining a stable clamping force and preventing slippage. Next, by using the cooperation of the locking block 21 and the locking groove 14, the pressing block 22 can be pressed to make the pressing plate 19 slide towards the inner wall of the storage groove 16, and squeeze the spring 18 to deform and contract, so that the locking block 21 and the locking groove 14 are separated. At this time, the sliding moving plate 15 can be manually pressed down to make the moving plate 15 squeeze the buffer spring 10 to deform, reduce the movement gap of the buffer rod 6, and thus adjust the buffering force of the buffer driven wheel 7, so as to quickly adapt to the buffering needs under different working conditions.
