Description

Technical Field

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

[0002] Carbon dioxide shielded welding, also known as carbon dioxide gas shielded arc welding, is a welding method that uses carbon dioxide gas as a shielding gas to weld parts. Due to its low cost, easy production of carbon dioxide gas, good weld formation when using short-circuit transfer, and the ability to obtain high-quality welded joints without internal defects by using welding wire containing deoxidizer, this welding method has become one of the most important welding methods for ferrous metal materials.

[0003] When the welding wire feeding device moves to the welding station, its power cord is often dragged along with the equipment, scattered or crossed on the ground. Due to the messy wiring and lack of effective fixing, it not only affects the cleanliness of the work area, but is also easy for operators or passing workers to step on or trip over, posing a significant safety hazard. In view of this, we propose a gas-shielded welding wire feeding device. Utility Model Content

[0004] The purpose of this invention is to provide a gas shielded welding wire feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas shielded welding wire feeding device, comprising a machine body, a winding drum rotatably connected to the inner wall of the machine body, a wire feeding component fixedly connected to the inner bottom surface of the machine body, a take-up roller rotatably connected to the side wall of the machine body, a wire feeding assembly for controlling the length of the power cord provided on the side wall of the take-up roller, and a wire pressing assembly for pressing the power cord toward the ground provided on the side wall of the machine body.

[0006] Preferably, the wire feeding assembly includes a ratchet fixedly connected to the side wall of the take-up roller, a rotating rod inserted into the side wall of the machine body, a pawl fixedly connected to the side wall of the rotating rod, a spring sleeved on the side wall of the rotating rod, and a limit frame fixedly connected to the side wall of the machine body.

[0007] Preferably, the ratchet engages with the pawl, so that the take-up roller can only take up the power cord in the opposite direction. One end of the spring abuts against the inner wall of the machine body, and the other end of the spring abuts against the pawl. The spring pushes the pawl, causing the pawl to engage with the ratchet.

[0008] Preferably, a handle is fixedly connected to the outer wall of the pawl, and a grip is fixedly connected to the side wall of the take-up roller. Pressing down the handle causes the pawl to move toward the machine body, at which point the pawl and ratchet are disengaged, and the power cord is unloaded.

[0009] Preferably, the wire pressing assembly includes a wire pressing cylinder, a wire guide is fixedly connected to the top of the wire pressing cylinder, a horizontal plate is fixedly connected to the side wall of the wire pressing cylinder, and a stud is rotatably connected to the top of the horizontal plate.

[0010] Preferably, the stud is threaded to the machine body, the wire pressing drum is L-shaped, the wire pressing drum is sleeved with the power cord, and the power cord is wound around the side wall of the take-up roller. Rotating the stud causes the wire pressing drum to rise or fall. When the welding wire feeding device is moved, the wire pressing drum rises to avoid the cable dragging and rubbing on the ground. When the welding wire feeding device is moved to the welding position, the wire pressing drum falls to keep the power cord close to the ground, reducing the probability of personnel tripping over the power cord.

[0011] Preferably, the side wall of the machine body is provided with a buffer assembly, the buffer assembly including a rotating roller rotatably connected to the side wall of the machine body, the side wall of the rotating roller having a through hole, a coil spring being sleeved on the side wall of the rotating roller, one end of the coil spring being fixedly connected to the rotating roller, and the other end of the coil spring being fixedly connected to the machine body.

[0012] Compared with the prior art, this utility model provides a gas-shielded welding wire feeding device, which has the following features:

[0013] Beneficial effects:

[0014] 1. This gas-shielded welding wire feeding device, through the setting of wire feeding and wire pressing components, and the engagement of pawl and ratchet, locks the take-up roller, preventing the power cord from being released further, thereby maintaining a stable cable length, avoiding cable dragging or tangling, and improving the cleanliness of the working environment. When the equipment reaches the target welding position, it presses the power cord to the ground, making the cable close to the ground. After the cable is close to the ground, there is no height difference, and no obvious resistance is generated when walking across it. This eliminates protruding obstacles, reduces the risk of tripping, and improves the safety of the welding site.

[0015] 2. This gas-shielded welding wire feeding equipment, through the setting of rotating rollers and coil springs, the rotating rollers rotate instantaneously, and the coil springs undergo elastic deformation accordingly, absorbing and buffering the impact force generated by the cable tension, avoiding the tension from acting directly on the take-up roller or power line connection, playing a buffering role, preventing damage to the power line interface or take-up roller structure due to excessive instantaneous tension, and improving safety.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a gas shielded welding wire feeding device, including a body 1, a winding drum 2 rotatably connected to the inner wall of the body 1, a wire feeding component 3 fixedly connected to the inner bottom surface of the body 1, a take-up roller 4 rotatably connected to the side wall of the body 1, a wire feeding assembly 5 for controlling the length of the power cord 9 provided on the side wall of the take-up roller 4, and a wire pressing assembly 7 for pressing the power cord 9 toward the ground provided on the side wall of the body 1.

[0023] In one embodiment of this utility model, the wire feeding assembly 5 includes a ratchet 501 fixedly connected to the side wall of the take-up roller 4, a rotating rod 502 inserted into the side wall of the machine body 1, a pawl 503 fixedly connected to the side wall of the rotating rod 502, a spring 504 sleeved on the side wall of the rotating rod 502, and a limit frame 505 fixedly connected to the side wall of the machine body 1. The ratchet 501 and the pawl 503 mesh, so that the take-up roller 4 can only take up the power line 9 in the opposite direction. One end of spring 504 abuts against the inner wall of the machine body 1, and the other end of spring 504 abuts against pawl 503. Spring 504 pushes pawl 503, so that pawl 503 engages with ratchet 501. A handle 6 is fixedly connected to the outer wall of pawl 503, and a grip is fixedly connected to the side wall of take-up roller 4. Pressing down handle 6 causes pawl 503 to move towards the machine body 1. At this time, pawl 503 and ratchet 501 are disengaged, and the power cord 9 is unloaded.

[0024] The wire pressing assembly 7 includes a wire pressing cylinder 701. A wire guide 702 is fixedly connected to the top of the wire pressing cylinder 701. A horizontal plate 703 is fixedly connected to the side wall of the wire pressing cylinder 701. A stud 704 is rotatably connected to the top of the horizontal plate 703. The stud 704 is threadedly connected to the machine body 1. The wire pressing cylinder 701 is L-shaped. The wire pressing cylinder 701 is connected to the power cord 9. The power cord 9 is wound around the side wall of the take-up roller 4. Rotating the stud 704 causes the wire pressing cylinder 701 to rise or fall. When the welding wire feeding device is moved, the wire pressing cylinder 701 rises to avoid the cable dragging and rubbing on the ground. When the welding wire feeding device is moved to the position where welding is required, the wire pressing cylinder 701 falls so that the power cord 9 is close to the bottom surface.

[0025] When the welding wire feeding device needs to be moved, the operator presses the handle 6. At this time, the pawl 503 moves inward against the elastic force of the spring 504 and disengages from the ratchet 501. The take-up roller 4 can rotate freely, and the power cord 9 can be released, thus providing a sufficient length of cable for the movement of the device. After the device is moved to the target welding position, the handle 6 is released. The spring 504 pushes the pawl 503 to automatically reset and re-engage with the ratchet 501, locking the take-up roller 4. The power cord 9 cannot be released further, thus maintaining a stable cable length, avoiding cable dragging or tangling, and improving the cleanliness of the working environment.

[0026] When the welding wire feeding device needs to be moved, rotate the stud 704 to raise the pressure drum 701, preventing the cable from dragging and abrading on the ground. When the equipment reaches the target welding position, rotate the stud 704 to lower the pressure drum 701, pressing the power cord 9 to the ground so that the cable is laid close to the ground. When people walk, their feet are usually a few centimeters off the ground, and they are more likely to trip over protruding objects on the ground, especially when they are tired, distracted, or have obstructed vision. With the cable close to the ground, there is no height difference, and there is no obvious resistance when the feet slide over it. This eliminates protruding obstacles, reduces the risk of tripping, and improves the safety of the welding site.

[0027] In addition, a buffer assembly 8 is provided on the side wall of the machine body 1. The buffer assembly 8 includes a rotating roller 801 rotatably connected to the side wall of the machine body 1. A through hole 802 is opened on the side wall of the rotating roller 801. A coil spring 803 is sleeved on the side wall of the rotating roller 801. One end of the coil spring 803 is fixedly connected to the rotating roller 801, and the other end of the coil spring 803 is fixedly connected to the machine body 1. When the equipment is working normally, the power cord 9 is led out through the through hole 802 on the outside of the rotating roller 801. The coil spring 803 is in a natural state and does not generate additional torque on the rotating roller 801. If, during use, the operator is accidentally tripped by the power cord 9 or the cable is suddenly pulled, the power cord 9 will drive the rotating roller 801 to rotate instantaneously. At this time, the coil spring 803 will undergo elastic deformation, absorbing and buffering the impact force generated by the cable stretching. This prevents the tension from acting directly on the take-up roller 4 or the connection of the power cord 9, thus playing a buffering role and preventing damage to the power cord 9 interface or the take-up roller 4 structure due to excessive instantaneous tension, thereby improving safety.

[0028] In this invention, when the welding wire feeding device needs to be moved, the operator presses the handle 6. At this time, the pawl 503 overcomes the elastic force of the spring 504 and moves inward, disengaging from the ratchet 501. The take-up roller 4 can rotate freely, and the power cord 9 can be released, thus providing a sufficient length of cable for the movement of the device. When the handle 6 is released, the spring 504 pushes the pawl 503 to automatically reset and re-engage with the ratchet 501, locking the take-up roller 4. The power cord 9 cannot be released further, thus maintaining a stable cable length and preventing the cable from being dragged or tangled. When the device reaches the target welding position, the stud 704 is rotated to lower the pressure cylinder 701, pressing the power cord 9 towards the ground, so that the cable is laid close to the ground, reducing the probability of people tripping when passing by.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
