Description

Technical Field

[0001] This application relates to the field of welding material production technology, and in particular to a flux-cored welding wire feeder. Background Technology

[0002] After the flux-cored welding wire is joined and drawn, it is first wound onto an I-beam spool. Then, during the fine drawing of the flux-cored welding wire, a wire feeding machine releases the wire from the I-beam spool and feeds it into a reducing device for fine drawing. The semi-finished product after fine drawing is wound back onto the I-beam spool and then transported to the packaging line. A wire feeding machine releases the semi-finished flux-cored welding wire from the I-beam spool, performs surface treatment, and then uses a layer winding machine to wind it back onto the I-beam spool for the final time. Finally, vacuum packaging is used to vacuum-pack the wound flux-cored welding wire, resulting in a spool of finished flux-cored welding wire ready for sale or use. Therefore, the wire feeding equipment is frequently used in the production process, and the time spent on the wire spool loading and unloading process is crucial to the production efficiency of flux-cored welding wire.

[0003] Some existing wire feeding equipment uses a method of mounting the wire spool on a horizontal rotating rod. For example, the wire feeding device disclosed in Chinese patent application number 202220407706.X is such a device. According to the disclosed technical solution, workers need to perform multiple operations to fix the wire spool. This type of wire feeding equipment obviously has a cumbersome operation process in picking up and putting down the wire spool, which affects the overall production efficiency of flux-cored wire. Utility Model Content

[0004] This application provides a flux-cored welding wire feeder, which can improve the efficiency of feeding and unloading welding wire spools.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: A flux-cored welding wire feeding frame includes a main support frame, a load-bearing bearing seat is fixedly installed in the middle of the main support frame, a rotating main shaft is inserted into the upper part of the load-bearing bearing seat and the two are rotatably connected, and a material placement disc is sleeved on the lower outer side of the rotating main shaft. The material placement disc is provided with a cylindrical inner support mechanism on its upper side, and the cylindrical inner support mechanism is coaxially installed on the outside of the rotating main shaft. After the I-beam disc with flux-cored welding wire is fitted onto the outside of the inner support mechanism of the cylinder, the inner support mechanism of the cylinder can clamp the I-beam disc by changing its own size. A side support frame is fixedly installed on one side of the main support frame, and a welding wire guiding unit is provided on the side support frame.

[0006] Furthermore, the lower end of the rotating spindle passes through the load-bearing bearing seat and is connected to the power output shaft of the reducer. The power input shaft of the reducer is connected to the power output shaft of the drive motor. The housings of the reducer and the drive motor are both fixedly connected to the support frame.

[0007] Furthermore, the cylindrical inner support mechanism includes four arc-shaped inner support plates. The four arc-shaped inner support plates are hinged from top to bottom to each other with an active adjusting rod, a first driven adjusting rod, and a second driven adjusting rod of equal length. The first driven adjusting rod and the second driven adjusting rod are parallel to each other, and the active adjusting rod and the first adjusting rod are symmetrical to each other. A movable sleeve, a first fixed sleeve, and a second fixed sleeve are sequentially installed on the rotating main shaft from top to bottom. The first fixed sleeve and the second fixed sleeve are both fixedly connected to the rotating main shaft. The movable sleeve is movably connected to the rotating main shaft and can move freely along its axial direction on the rotating main shaft. The adjacent sides of the active adjusting rods on the four arc-shaped inner support plates are all hinged to the movable sleeve; the adjacent sides of the first driven adjusting rods on the four arc-shaped inner support plates are all hinged to the first fixed sleeve; and the adjacent sides of the second driven adjusting rods on the four arc-shaped inner support plates are all hinged to the second fixed sleeve.

[0008] Furthermore, the upper part of the rotating spindle is provided with an external thread on the outer side, and an adjusting sleeve is threadedly connected to the external threaded part of the rotating spindle. The movable sleeve is sleeved on the outer side of the adjusting sleeve and the two are rotatably connected.

[0009] Furthermore, the portion of the adjusting sleeve located on the upper side of the movable sleeve is provided with multiple insertion holes evenly distributed along its circumference.

[0010] Furthermore, the material placement disc is located between the second fixed sleeve and the load-bearing bearing seat; The material placement disc includes an outer ring frame and a lower support frame. The inner side of the outer ring frame is provided with multiple guide rods, which form a cross-shaped sliding groove within the outer ring frame. The lower ends of the four arc-shaped inner support plates are respectively inserted into the four support slots of the sliding groove. The center of the sliding groove is sleeved on the outside of the rotating main shaft and fixedly connected to the rotating main shaft through the lower support frame.

[0011] Furthermore, the welding wire guiding unit includes two parallel vertical rollers, which are rotatably sleeved on the outside of the vertical shaft. The upper and lower ends of the vertical shaft are respectively provided with a horizontal plate fixedly connected to the side support. The horizontal plate is provided with a first position adjustment groove. The upper and lower ends of the vertical shaft are detachably installed in the two first position adjustment grooves by nuts.

[0012] Furthermore, the welding wire guiding unit also includes two outward expansion brackets and two horizontal rollers. The two outward expansion brackets are fixedly installed on the side of the side stand away from the main support frame, and two parallel channel steels are fixedly connected between the two outward expansion brackets. Each of the two channel steels is provided with a second position adjustment groove on its adjacent side.

[0013] In summary, this application includes at least one of the following beneficial technical effects: Flux-cored welding wire is usually wound on an I-beam reel, which has a through-hole in the center. When using the wire feeding frame of this application, the worker only needs to place the I-beam reel with the welding wire wound on it onto the inner support mechanism of the cylinder. The inner support mechanism of the cylinder clamps the wire reel through the hole in the center of the I-beam reel by expanding outwards. When the wire reel needs to be removed, the inner support mechanism of the cylinder simply retracts inwards within the hole in the center of the I-beam reel, and the wire feeding operation can be quickly removed. The entire installation and disassembly process is simple and quick, and the inner support mechanism of the cylinder can accommodate various specifications of wire reels, which makes it more adaptable to different products in actual production.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0018] like Figures 1-3 As shown, this application discloses a flux-cored welding wire feeding frame, which includes a main support frame 1. A load-bearing bearing seat 2 is fixedly installed in the middle of the main support frame 1. A rotating main shaft 3 is inserted into the upper part of the load-bearing bearing seat 2 and the two are rotatably connected. A material placement disc 4 is sleeved on the outer side of the lower end of the rotating main shaft 3. A cylindrical inner support mechanism 5 is provided on the upper side of the material placement disc 4, and the cylindrical inner support mechanism 5 is coaxially installed on the outside of the rotating main shaft 3. After the I-beam disc with flux-cored welding wire is sleeved on the outside of the inner support mechanism 5 of the cylinder, the inner support mechanism 5 of the cylinder can clamp the I-beam disc by changing its own size. A side support frame 6 is fixedly installed on one side of the main support frame 1, and a welding wire guiding unit 7 is provided on the side support frame 6.

[0019] In the above embodiments, the support frame 1 of this application is welded from multiple square tubes of different lengths. The load-bearing bearing seat 2 and the rotating spindle 3 are rotatably connected and fixedly installed in the middle of the support frame 1. In this way, the rotating spindle 3 can achieve a low-resistance free rotation effect on the support frame 1 through the load-bearing bearing seat 2. The rotating spindle 3 is in a vertical state on the support frame 1. If the welding wire spool is directly sleeved on the rotating spindle 3, the lower end of the welding wire spool will contact the upper side of the support frame 1. This will cause frictional wear between the lower side of the welding wire spool and the support frame 1 during rotation. However, by setting a material placement disc 4 on the rotating spindle 3, the position of the welding wire spool after it is sleeved on the rotating spindle 3 can be limited, so that it will not contact the support frame 1 when rotating with the rotating spindle 3, thereby avoiding frictional wear.

[0020] The rotating spindle 3 of this application is further equipped with a cylindrical inner support mechanism 5 on its outer side. Workers can change the diameter of its cross-section by operating this mechanism. The flux-cored welding wire is usually wound on an I-beam reel, which has a through-hole in the center. When using the wire feeding frame of this application, the worker only needs to place the I-beam reel with the welding wire wound on the cylindrical inner support mechanism 5. The cylindrical inner support mechanism 5 clamps the wire reel through the hole in the center of the I-beam reel by expanding outwards. When the wire reel needs to be removed, the cylindrical inner support mechanism 5 only needs to be retracted inwards within the hole in the center of the I-beam reel to quickly remove the wire feeding operation. The entire installation and disassembly process is simple and quick, and the cylindrical inner support mechanism 5 can accommodate various specifications of welding wire reels, which makes it more adaptable to different products in actual production.

[0021] The main support frame 1 of this application is also provided with a side support frame 6 on one side. The welding wire guiding unit 7 on the side support frame 6 can guide the movement direction of the welding wire released from the welding wire spool so that the welding wire released from the welding wire spool can smoothly reach the next process.

[0022] Furthermore, such as Figure 2 and Figure 3 As shown, the lower end of the rotating main shaft 3 passes through the load-bearing bearing seat 2 and is connected to the power output shaft of the reducer 8. The power input shaft of the reducer 8 is connected to the power output shaft of the drive motor 9. The housings of the reducer 8 and the drive motor 9 are both fixedly connected to the support frame 1.

[0023] In the above embodiments, the welding wire reel mounted on the rotating spindle 3 needs to rotate together with the rotating spindle 3 to perform the wire feeding operation. If the rotating spindle 3 and the welding wire reel are driven manually, it will inevitably increase the labor intensity of the workers. Therefore, this application provides a drive motor 9 on the lower side of the support frame 1 to provide driving force for the rotation of the rotating spindle 3. The rotating spindle 3 not only has structural components such as the cylindrical inner support mechanism 5 and the material placement disc 4, but also has a welding wire reel mounted on it. These will increase the torque that the drive motor 9 has to bear when the rotating spindle 3 rotates. The reducer 8 added between the drive motor 9 and the rotating spindle 3 in this application is a mechanical device that reduces the output speed of the high-speed rotating motor while increasing the torque. When the motor is in use, even after the power is cut off, its output shaft may continue to rotate for a period of time due to inertia. This situation may cause the welding wire between the welding wire guide unit 7 and the rotating main shaft 3 to become messy due to the sudden increase. Therefore, in order to prevent the driven equipment from not stopping immediately or from accidentally rotating in the opposite direction, the reducer 8 of this application can be a worm gear reducer 8.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, the cylindrical inner support mechanism 5 includes four arc-shaped inner support plates 51. The four arc-shaped inner support plates 51 are hinged from top to bottom to each other on their close sides with an active adjusting rod 52, a first driven adjusting rod 53 and a second driven adjusting rod 54 of equal length. The first driven adjusting rod 53 and the second driven adjusting rod 54 are parallel to each other, and the active adjusting rod 52 and the first driven adjusting rod 53 are symmetrical to each other. A movable sleeve 55, a first fixed sleeve 56, and a second fixed sleeve 57 are installed sequentially from top to bottom on the rotating main shaft 3. The first fixed sleeve 56 and the second fixed sleeve 57 are both fixedly connected to the rotating main shaft 3. The movable sleeve 55 is movably connected to the rotating main shaft 3 and can move freely along its axial direction on the rotating main shaft 3. The active adjusting rods 52 on the four arc-shaped inner support plates 51 are all hinged to the movable sleeve 55 on their respective adjacent sides. The first driven adjusting rods 53 on the four arc-shaped inner support plates 51 are all hinged to the first fixed sleeve 56 on their respective adjacent sides. The second driven adjusting rods 54 on the four arc-shaped inner support plates 51 are all hinged to the second fixed sleeve 57 on their respective adjacent sides.

[0025] In the above embodiments, the arc-shaped inner support plate 51 of this application includes an arc-shaped plate and a square tube located on its concave side. The square tube located on the concave side of the arc-shaped plate facilitates the installation of a hinge support for hinged connection with the active adjusting rod 52, the first driven adjusting rod 53, and the second driven adjusting rod 54. The first driven adjusting rod 53 and the second driven adjusting rod 54 of this application can form a four-bar linkage structure between the rotating main shaft 3 and the arc-shaped inner support plate 51. The active adjusting rod 52 is symmetrical to the first driven adjusting rod 53 between the arc-shaped inner support plate 51 and the rotating main shaft 3. The adjacent ends of all the active adjusting rods 52 are connected to the movable sleeve 55. When the worker moves the movable sleeve 55 on the rotating main shaft 3, the first driven adjusting rod 53 and the second driven adjusting rod 54 will change synchronously, thereby changing the distance between the arc-shaped inner support plate 51 and the rotating main shaft 3. Since the positional changes of all the arc-shaped inner support plates 51 are synchronous, the diameter of the circle formed by the outer contour of the arc-shaped inner support plate 51 will also change in real time. Furthermore, after the welding wire spool is placed on the outside of the cylindrical inner support mechanism 5, the worker only needs to adjust the movable sleeve 55 to quickly achieve the effect of fixing welding wire spools of different specifications using the four arc-shaped inner support plates 51 in the cylindrical inner support mechanism 5.

[0026] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the outer side of the upper part of the rotating spindle 3 is provided with an external thread, and the external threaded part of the rotating spindle 3 is threadedly connected to the adjusting sleeve 10. The movable sleeve 55 is sleeved on the outer side of the adjusting sleeve 10 and the two are rotatably connected.

[0027] In the above embodiments, the adjusting sleeve 10 is sleeved on the outer side of the portion of the rotating spindle 3 with external threads. This allows the worker to change the real-time position of the adjusting sleeve 10 on the rotating spindle 3 by rotating it. Furthermore, as soon as rotation of the adjusting sleeve 10 stops, it immediately stops at its current position due to the limiting effect of the threaded connection. The movable sleeve 55, which is hinged to all the active adjusting rods 52, is sleeved on the outer side of the adjusting sleeve 10, and the two are rotatably connected. Thus, during the rotation of the adjusting sleeve 10, the movable sleeve 55, which is constrained by the first driven adjusting rod 53, the second driven adjusting rod 54, and the arc-shaped inner support plate 51, will not limit the rotation of the adjusting sleeve 10. The movable sleeve 55 and the adjusting sleeve 10 of this application are rotatably connected. When the adjusting sleeve 10 rotates on the rotating main shaft 3, the movable sleeve 55 does not need to rotate with the adjusting sleeve 10, but the movable sleeve 55 will move together with the adjusting sleeve 10 along the axial direction of the rotating main shaft 3. This allows the worker to adjust the range of the arc-shaped inner support plate 51 outside the rotating main shaft 3 by rotating the adjusting sleeve 10. Moreover, the adjustment process is linear, which can further improve the adaptability and fixing effect of the wire feeding frame of this application to different specifications of welding wire reels.

[0028] Furthermore, such as Figure 3 As shown, the portion of the adjusting sleeve 10 located on the upper side of the movable sleeve 55 is provided with multiple insertion holes 11 evenly distributed along its circumference.

[0029] In the above embodiments, the main shaft 3 needs to rotate continuously during the wire feeding process. If the outer side of the adjusting sleeve 10 is fixed with a certain handle (to save effort in rotating the adjusting sleeve 10, the length of the adjusting sleeve 10 is generally set to be relatively long), the adjusting sleeve 10 may cause injury to nearby workers. In this application, multiple insertion holes 11 are provided on the periphery of the adjusting sleeve 10 in the manner described above. When the adjusting sleeve 10 needs to be adjusted, the worker can insert an independent handle into the insertion hole 11 of the adjusting sleeve 10 to rotate the adjusting sleeve 10. After adjustment, the worker can pull the independent handle out of the insertion hole 11, and the adjusting sleeve 10 can return to its initial small diameter state. Because its coverage area is small, the risk of injury to nearby workers can be reduced when it rotates with the main shaft 3.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the material placement disc 4 is located between the second fixed sleeve 57 and the load-bearing bearing seat 2; the material placement disc 4 includes an outer ring frame 41 and a lower support frame 42. The inner side of the outer ring frame 41 is provided with multiple guide rods 43, which form a cross-shaped sliding groove 44 inside the outer ring frame 41. The lower ends of the four arc-shaped inner support plates 51 are respectively inserted into the four support slots of the sliding groove 44; the center of the sliding groove 44 is sleeved on the outside of the rotating main shaft 3 and fixedly connected to the rotating main shaft 3 through the lower support frame 42.

[0031] In the above embodiments, the cross-shaped slide groove 44 composed of guide rods 43 includes four interconnected support slots, which are perpendicular to each other. The lower ends of the four arc-shaped inner support plates 51 are respectively inserted into the four support slots of the slide groove 44. Thus, when the relative positions of the arc-shaped inner support plates 51 and the rotating main shaft 3 change, the slide groove 44 composed of multiple guide rods 43 can provide guidance for their expansion and contraction, making the change process of the arc-shaped inner support plates 51 smoother. The lower bracket 42 located on the lower side of the outer ring frame 41 is fixedly connected to a portion of the guide rods 43 forming the center of the slide groove 44, and the lower bracket 42 is fixedly connected to the rotating main shaft 3. Thus, the lower bracket 42, guide rods 43, and outer ring frame 41 can form a solid and stable support structure outside the rotating main shaft 3, which can hold the welding wire spool.

[0032] Furthermore, such as Figure 1 and Figure 2As shown, the welding wire guiding unit 7 includes two parallel vertical rollers 71. The vertical rollers 71 are rotatably sleeved on the outside of the vertical shaft 72. The upper and lower ends of the vertical shaft 72 are respectively provided with a horizontal plate 73 fixedly connected to the side support 6. The horizontal plate 73 is provided with a first position adjustment groove 74. The upper and lower ends of the vertical shaft 72 are detachably installed in the two first position adjustment grooves 74 by nuts.

[0033] In the above embodiments, each vertical roller 71 of this application is provided with a vertical shaft 72 rotatably connected to it. The two ends of the vertical shaft 72 are respectively installed on the horizontal plates 73 located on its upper and lower sides, so that the vertical roller 71 can rotate smoothly on the vertical shaft 72.

[0034] This application provides a first position adjustment groove 74 on the horizontal plate 73 at both ends of the vertical shaft 72. The upper and lower ends of the vertical shaft 72 can be provided with external threads. A nut is installed on the upper and lower parts of the external thread of the vertical shaft 72 on the corresponding side of the first position adjustment groove 74. When the two nuts are close to each other, the clamping force can be used to fix the position of the vertical shaft 72. When the two nuts are far apart, the worker can change its position along the length of the first position adjustment groove 74. In this way, when in use, the worker can adjust the distance between the two vertical rollers 71 to a suitable state according to the specific wire diameter of the welding wire on the welding wire spool. Because the vertical rollers 71 and the vertical shaft 72 are rotatably connected, when the welding wire passes between the two vertical rollers 71, even if the welding wire comes into contact with the vertical rollers 71, the vertical rollers 71 can resolve the possible frictional wear between the two through the rotation effect.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the welding wire guiding unit 7 also includes two outward expansion brackets 75 and two horizontal rollers 76. The two outward expansion brackets 75 are fixedly installed on the side of the side support 6 away from the main support frame 1, and two parallel channel steels 77 are fixedly connected between the two outward expansion brackets 75. A second position adjustment groove 78 is provided on the side of the two channel steels 77 that are close to each other. The horizontal roller 76 is rotatably sleeved on the outside of a horizontal shaft 79, both ends of which are connected to two second position adjustment grooves 78 by nuts; and the two horizontal rollers 76 are parallel to each other between the two channel steels 77.

[0036] In the above embodiments, the outward expansion bracket 75 located outside the side support 6 can provide a certain interval between the two horizontal rollers 76 and the two vertical rollers 71, so that when the welding wire is transferred from between the two vertical rollers 71 to between the two horizontal rollers 76, it can provide sufficient transition space for the change of the welding wire position. In this application, two horizontal rollers 76 are mounted between two outwardly expanding brackets 75 via two channel steels 77. A second position adjustment groove 78 is provided along the length of the vertical channel steel 77. A horizontal shaft 79 is inserted into the center of each horizontal roller 76 and rotatably connected to it. Both ends of the horizontal shaft 79 are respectively inserted into the two second position adjustment grooves 78. The two ends of the horizontal shaft 79 are fixed to their respective second position adjustment grooves 78 using the same method as the vertical shaft 72 and the first position adjustment groove 74 in the previous embodiment. Nuts are used to fix both ends of the horizontal shaft 79. Thus, when there is a need to adjust the distance between the two horizontal rollers 76, the worker can loosen the nuts and adjust the position of the horizontal shaft 79 in the second position adjustment groove 78 in the vertical direction. Once the distance between the two horizontal rollers 76 meets the required wire diameter for the welding wire, it can be re-fixed.

[0037] The two vertical rollers 71 of this application are in a vertical position. Their main function is to gather the welding wire in the horizontal direction to the middle before it reaches the next process (such as welding wire fine drawing equipment or welding wire surface treatment equipment), that is, to align the horizontal position of the welding wire with the welding wire entry end of the next process. The two horizontal rollers 76 can further guide the welding wire in the vertical direction after it is output from between the two vertical rollers 71, so that the height of the welding wire after it is output from between the two horizontal rollers 76 is close to that of the welding wire entry point of the next process. In this way, the welding wire released from the welding wire reel can enter the next process straight after passing through the welding wire guiding unit 7 of this application, which provides convenience for the next process of welding wire production.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
