Description

Technical Field

[0001] This utility model relates to the field of wire feeding technology, and more specifically to a gas-shielded welding wire feeding device. Background Technology

[0002] The wire feeding device is a core auxiliary equipment in gas shielded welding operations. Its wire feeding stability and wire cleanliness directly determine the welding quality. If the surface of the welding wire is covered with impurities such as oil and dust, it will cause defects such as porosity and slag inclusions during the welding process, reducing the mechanical properties of the weld. The impact of impurities is even more significant in high-precision welding scenarios such as pressure vessels and steel structures.

[0003] Research indicates that the commonly used solution is a fixed brush + passive cleaning wire feeding device. A fixed brush is placed along the wire feeding path, and the welding wire cleans itself by moving along the brush. The brush is fixed to a bracket with bolts. This solution is simple in structure, but has significant drawbacks: passive cleaning relies on the relative friction between the welding wire and the brush, resulting in insufficient cleaning power and difficulty in completely removing sticky impurities such as oil; after the brush wears out, multiple sets of bolts need to be tightened for replacement, which is cumbersome and can easily cause the wire feeding path to shift during replacement, affecting welding accuracy.

[0004] The shortcomings of the existing technology: In current wire feeders, the welding wire is usually placed directly in the factory or workshop after installation. Since there is a lot of dust in the factory or workshop, the surface of the welding wire will be contaminated with oil and dust, which will affect the normal use of the welding wire and needs to be improved.

[0005] Therefore, there is a need to provide a gas-shielded welding wire feeding device to solve the above-mentioned problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas-shielded welding wire feeding device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a gas-shielded welding wire feeding device, including a base, a bracket fixedly connected to the top of the base near the left side, a fixed seat fixedly connected to the top of the inner wall of the bracket near the middle, a winding roller fixedly connected to the top of the base near the right side, a gas-shielded welding wire body wound around the middle of the winding roller, a cleaning cloth movably sleeved on the outer wall of the left end of the gas-shielded welding wire body, and a mounting seat folded and movably sleeved on the outer wall of the right end of the cleaning cloth; The gas-shielded welding wire feeding device also includes: A rotating assembly is disposed between the bottom end of the fixed base and the outer wall of the mounting base, and is used to drive the mounting base and the cleaning cloth to rotate to clean the oil stains on the outer wall of the gas shielded welding wire body. The disassembly and assembly component is located on the outer right side of the cleaning cloth and at the mounting base, and is used to limit and fix the cleaning cloth and the mounting base and to quickly disassemble them. Preferably, the rotating component includes: Two support plates, the top of the two support plates are fixedly connected to the bottom of the fixed base, and the bottom of the two support plates are rotatably sleeved with limit rollers. The outer walls of the two limit rollers slide against toothed rings, and the inner walls of the toothed rings are fixedly sleeved with the outer walls of the mounting base. A driving mechanism is provided between the toothed ring and the fixed base, and is used to drive the toothed ring to rotate the mounting base.

[0008] Preferably, the driving mechanism includes two upright plates, the top ends of the two upright plates are fixedly connected to the bottom end of the fixed base, a drive motor is fixedly connected to the outer side of one of the upright plates, the transmission end of the drive motor passes through the upright plate and is fixedly connected to a gear, the two ends of the gear are rotatably sleeved between the two upright plates, and the outer wall of the gear is meshed with the outer wall of the toothed ring.

[0009] Preferably, the disassembly and assembly assembly includes a second limiting sleeve, the inner wall of which is movably sleeved on the outer wall of the cleaning cloth, a second collar fixedly connected to the front end of the second limiting sleeve, an annular adjusting rod movably sleeved on the inner wall of the second collar, a third collar movably sleeved on the bottom end of the annular adjusting rod, a first limiting sleeve fixedly connected to the outer wall of the third collar, and the inner wall of the first limiting sleeve movably sleeved on the bottom of the outer wall of the cleaning cloth.

[0010] Preferably, the middle part of the annular adjusting rod is movably sleeved at both ends of the second collar, the top ends of the two collars are fixedly connected to the first collar, the inner wall of the first collar is movably sleeved with the top of the annular adjusting rod, and the outer wall of the first collar is fixedly connected to the pressure plate.

[0011] Preferably, an H-shaped limiting plate is movably sleeved at the opposite end of the limiting sleeve two and the limiting sleeve one via a movable column.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model, by providing a fixed base and a rotating assembly, allows for the feeding of one end of the gas-shielded welding wire body through a cleaning cloth. Supported by two upright plates, the drive motor is activated, causing the gear to rotate, which in turn rotates the toothed ring meshing with it. This, in turn, rotates the mounting base in the middle of the toothed ring and the cleaning cloth, facilitating the rotational cleaning of oil stains on the outer wall of the gas-shielded welding wire body after passing through the cleaning cloth, ensuring efficient wire feeding.

[0013] 2. This utility model, by providing a disassembly and assembly component, allows for quick disassembly and replacement of the cleaning cloth. By rotating the pressure plate, the first collar rotates on the outer wall of the annular adjusting rod, which in turn rotates the two sleeve rods in the middle of the annular adjusting rod. Under the movable support of the H-shaped limiting plate, the second limiting sleeve block is pushed to separate from the outer wall of the cleaning cloth, releasing the pressure on the cleaning cloth from the second limiting sleeve block and the pair of limiting sleeve blocks. This facilitates the removal of the disassembly and assembly component from the outer wall of the cleaning cloth, and the removal of the cleaning cloth from the mounting base, enabling quick replacement of the cleaning cloth and further ensuring the cleaning efficiency when feeding the gas-shielded welding wire body.

[0019] 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 scope of protection of the present utility model.

[0020] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0021] Example 1 This utility model is a gas-shielded welding wire feeding device, including a base 2, a bracket 1 fixedly connected to the top of the base 2 near the left side, a fixing seat 7 fixedly connected to the top of the inner wall of the bracket 1 near the middle, a winding roller 3 fixedly connected to the top of the base 2 near the right side, a gas-shielded welding wire body 4 wound around the middle of the winding roller 3, a cleaning cloth 5 movably sleeved on the outer wall of the left end of the gas-shielded welding wire body 4, and a mounting seat 9 folded and movably sleeved on the outer wall of the right end of the cleaning cloth 5. The gas-shielded welding wire feeding device also includes: Rotating component 8 is disposed between the bottom end of fixed base 7 and the outer wall of mounting base 9, and is used to drive mounting base 9 and cleaning cloth 5 to rotate and clean oil stains on the outer wall of gas shielded welding wire body 4. The disassembly and assembly component 6 is located on the outer right side of the cleaning cloth 5 and the mounting base 9, and is used to limit and fix the cleaning cloth 5 and the mounting base 9 and to quickly disassemble them.

[0022] Rotating component 8 includes: Two support plates 802 are fixedly connected at their top ends to the bottom end of the fixed base 7. The bottom ends of the two support plates 802 are rotatably sleeved with limit rollers 806. The outer walls of the two limit rollers 806 slide against toothed rings 805. The inner wall of the toothed rings 805 is fixedly sleeved with the outer wall of the mounting base 9. The drive mechanism is located between the toothed ring 805 and the fixed seat 7, and is used to drive the toothed ring 805 to rotate the mounting seat 9.

[0023] The drive mechanism includes two upright plates 803. The top ends of the two upright plates 803 are fixedly connected to the bottom end of the fixed base 7. A drive motor 801 is fixedly connected to the outside of one upright plate 803. A gear 804 is fixedly connected through the drive end of the drive motor 801 through the upright plate 803. The two ends of the gear 804 are rotatably sleeved between the two upright plates 803. The outer wall of the gear 804 meshes with the outer wall of the toothed ring 805.

[0024] In this embodiment, as Figure 1-3 As shown, supported by two upright plates 803, the drive motor 801 is turned on, which drives the gear 804 to rotate, and in turn drives the toothed ring 805 that meshes with it to rotate. This drives the mounting seat 9 and cleaning cloth 5 in the middle of the toothed ring 805 to rotate, which is beneficial for rotating and cleaning the oil stains on the outer wall of the gas shielded welding wire body 4 that has passed through the cleaning cloth 5, ensuring wire feeding efficiency. Supported by two support plates 802, the limiting roller 806 rotates relative to the toothed ring 805 as it rotates, providing stable support for the rotation of the toothed ring 805.

[0025] Example 2 The difference from Embodiment 1 is that this embodiment discloses that the disassembly and assembly component 6 includes a second limiting sleeve 610, the inner wall of the second limiting sleeve 610 is movably sleeved on the outer wall of the cleaning cloth 5, the front end of the second limiting sleeve 610 is fixedly connected to a second collar 605, the inner wall of the second collar 605 is movably sleeved with an annular adjusting rod 607, the bottom end of the annular adjusting rod 607 is movably sleeved with a third collar 606, the outer wall of the third collar 606 is fixedly connected to a first limiting sleeve 608, and the inner wall of the first limiting sleeve 608 is movably sleeved with the bottom of the outer wall of the cleaning cloth 5.

[0026] The middle part of the annular adjusting rod 607 is movably sleeved at both ends of the second collar 605, and the top ends of the two collars 603 are fixedly connected to the first collar 602. The inner wall of the first collar 602 is movably sleeved with the top of the annular adjusting rod 607, and the outer wall of the first collar 602 is fixedly connected to the pressure plate 601.

[0027] An H-shaped limiting plate 609 is movably sleeved at the opposite end of the limiting sleeve 2 610 and the limiting sleeve 1 608 via a movable column.

[0028] In this embodiment, as Figure 1-2 and Figure 4 As shown, rotating the pressure plate 601 causes the first collar 602 to rotate on the outer wall of the annular adjusting rod 607, which in turn causes the two sleeve rods 603 to rotate in the middle of the annular adjusting rod 607. Under the movable support of the H-shaped limiting plate 609, the second limiting sleeve 610 is pushed to separate from the outer wall of the cleaning cloth 5, releasing the pressure of the second limiting sleeve 610 and the first limiting sleeve 608 on the cleaning cloth 5. This facilitates the removal of the disassembly component 6 from the outer wall of the cleaning cloth 5, and then the cleaning cloth 5 can be removed from the mounting base 9.

[0029] The working principle of this utility model is as follows: When one end of the gas-shielded welding wire body 4 is fed through the cleaning cloth 5, the drive motor 801 is turned on under the support of the two upright plates 803, driving the gear 804 to rotate, which in turn drives the toothed ring 805 to rotate. This causes the mounting seat 9 in the middle of the toothed ring 805 and the cleaning cloth 5 to rotate, thus rotating and cleaning the oil stains on the outer wall of the gas-shielded welding wire body 4 that have passed through the cleaning cloth 5, ensuring wire feeding efficiency. Under the support of the two support plates 802, the limiting roller 806 rotates relative to the toothed ring 805 as it rotates, thus controlling the rotation of the toothed ring 805. When quickly replacing the cleaning cloth 5, rotate the pressure plate 601 to rotate the first collar 602 on the outer wall of the annular adjusting rod 607. This, in turn, causes the two sleeve rods 603 to rotate in the middle of the annular adjusting rod 607. Under the movable support of the H-shaped limiting plate 609, the second limiting sleeve 610 is pushed to separate from the outer wall of the cleaning cloth 5, releasing the pressure of the second limiting sleeve 610 and the first limiting sleeve 608 on the cleaning cloth 5. The disassembly and assembly component 6 can then be removed from the outer wall of the cleaning cloth 5, and the cleaning cloth 5 can be taken out from the mounting base 9 for quick replacement.
