Description

Technical Field

[0001] This utility model relates to the field of welding wire spool technology, specifically to a welding wire spool anti-wire jumping device and a welding wire spool. Background Technology

[0002] With the continuous improvement of industrial automation, welding technology has been widely used in many fields. During the welding process, welding wire, as a crucial consumable material, directly affects welding quality and production efficiency due to the stability and accuracy of its transmission and feeding. In actual welding processes, due to factors such as friction and tension of the welding wire, wire spools may experience phenomena such as wire skipping and tangling. This not only affects the welding effect but may also lead to equipment failure, production interruption, and in severe cases, even threaten worker safety.

[0003] Currently, many welding wire spools are not designed or used with the need to prevent wire slippage in mind. Most existing welding wire spool devices employ simple fixing methods, lacking effective control over the welding wire. During welding, when the wire is pulled out, uneven pressure or an unreasonable device structure can cause excessive tension, leading to wire slippage or breakage. This not only reduces welding quality but also increases the risk of material waste and equipment failure. Utility Model Content

[0004] This utility model proposes a wire skipping prevention device and a wire spool, solving the problem that most existing wire spool devices in related technologies adopt simple fixing methods and lack effective control over the welding wire. During the welding process, when the welding wire is pulled out, due to uneven pressure or unreasonable device structure, the welding wire may be subjected to excessive tension, resulting in wire skipping or breakage.

[0005] The technical solution of this utility model is as follows:

[0006] A wire spool anti-wire-slipping device, comprising:

[0007] Mounting plate, with L-shaped connecting brackets slidably mounted at both ends of the mounting plate, and mounting rings fixed at the bottom of each L-shaped connecting bracket, with movable rings rotatably mounted inside the mounting rings;

[0008] A pressure roller mechanism is installed below the mounting plate, and the pressure roller mechanism is connected to the mounting plate through a pressing mechanism.

[0009] A connecting mechanism is installed on the side wall of an L-shaped connecting frame and is fixedly connected to the mounting frame of the welding wire spool by bolts.

[0010] Preferably, the pressure roller mechanism includes a support, and a pressure roller is rotatably mounted between the bottom sidewalls of the support.

[0011] Preferably, the pressing mechanism includes two symmetrically arranged sleeves, each sleeve being fixed to the top wall of the mounting plate, and a sliding shaft being slidably installed inside the sleeve;

[0012] The bottom ends of the sliding shafts slide through the mounting plate and are fixedly connected to the top wall of the bracket. The top ends of the sliding shafts slide through the top wall of the sleeve. A connecting plate is fixed between the top ends of the two sliding shafts. A limit plate is fixed on the shaft of the sliding shaft inside the sleeve.

[0013] The limiting plate is slidably installed inside the sleeve, and a spring is fixed between the top wall of the limiting plate and the top wall of the inner cavity of the sleeve;

[0014] The spring is sleeved on the outside of the slide shaft.

[0015] Preferably, the connecting mechanism includes an L-shaped plate, and a movable plate is slidably sleeved on one end of the horizontal plate of the L-shaped plate;

[0016] A baffle is fixed at one end of the movable plate inside the L-shaped plate, and the other end of the movable plate is fixedly connected to the L-shaped connecting frame.

[0017] Preferably, a limiting groove is formed in the horizontal plate of the L-shaped plate, and the baffle is slidably installed in the limiting groove.

[0018] Preferably, the vertical sidewall of the L-shaped plate has a through mounting hole.

[0019] Preferably, both ends of the mounting plate are provided with sliding grooves, one end of the L-shaped connecting bracket is slidably installed in the corresponding sliding groove, the top wall of the L-shaped connecting bracket is fixed with a threaded post, and a nut is screwed onto the threaded post.

[0020] Preferably, the top wall of the mounting plate has a through-hole with a connecting groove, and the threaded column is slidably installed in the through-hole.

[0021] A welding wire spool includes a welding wire spool body and a welding wire spool anti-slip device installed on the welding wire spool body.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The pressure roller mechanism and pressing mechanism in this utility model can continuously apply stable pressure to the welding wire, ensuring that the welding wire remains stable during the extraction process and avoiding wire skipping. This design greatly improves the stability of the welding process and the welding quality, reduces welding defects caused by wire skipping, and thus improves production efficiency. At the same time, the L-shaped connecting frame is slidably installed at both ends of the mounting plate and fixed by the threaded post and nut. This setting method can facilitate the separation of the anti-wire skipping device from the welding wire spool body when replacing the welding wire spool body.

[0024] 2. The pressing roller mechanism in this utility model adopts a rotatable pressing roller design, which avoids excessive friction between the welding wire and the pressing roller and reduces the risk of surface wear of the welding wire. This not only ensures the welding quality, but also extends the service life of the anti-slipping device of the welding wire spool and reduces maintenance and replacement costs.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] like Figures 1-3 As shown, this embodiment proposes:

[0035] A wire spool anti-wire-slipping device, comprising:

[0036] Mounting plate 1, with L-shaped connecting brackets 2 slidably mounted at both ends of mounting plate 1, and mounting rings 3 fixed at the bottom of each L-shaped connecting bracket 2, with movable rings 4 rotatably mounted inside the mounting rings 3;

[0037] The pressure roller mechanism 5 is installed below the mounting plate 1 and is connected to the mounting plate 1 through the pressing mechanism 6.

[0038] The connecting mechanism 7 is installed on the side wall of the L-shaped connecting frame 2 on one side, and is fixedly connected to the mounting frame of the welding wire spool by bolts.

[0039] Both ends of the mounting plate 1 are provided with sliding grooves 8. One end of the L-shaped connecting bracket 2 is slidably installed in the corresponding sliding groove 8. The top wall of the L-shaped connecting bracket 2 is fixed with a threaded post 9, and a nut 10 is screwed onto the threaded post 9.

[0040] The top wall of the mounting plate 1 has a through-hole 11 with a connecting groove 8, and the threaded column 9 is slidably installed in the through-hole 11.

[0041] In this embodiment, the mounting plate 1 provides an installation platform for the overall device. The connecting plate 1 is installed on both sides of the welding wire spool body 12 via the L-shaped connecting frame 2 and the mounting ring 3 and movable ring 4 at its bottom. The movable ring 4 is sleeved on both sides of the welding wire spool body 12. At the same time, the L-shaped connecting frame 2 is fixed to the mounting frame of the welding wire spool via the connecting mechanism 7, so that the mounting plate 1 is always kept above the welding wire spool body 12. The pressing mechanism 6 enables the pressure roller mechanism 5 to always press on the top of the welding wire on the welding wire spool body 12, so that the welding wire will not jump during the extraction process. Meanwhile, the L-shaped connecting frame 2 is slidably installed on both ends of the mounting plate 1 and fixed by the threaded post 9 and nut 10. This arrangement makes it easy to separate the anti-slip device of the welding wire spool from the welding wire spool body 12 when replacing the welding wire spool body 12.

[0042] Example 2

[0043] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0044] The pressure roller mechanism 5 includes a bracket 51, and a pressure roller 52 is rotatably mounted between the bottom side walls of the bracket 51.

[0045] The pressing mechanism 6 includes two symmetrically arranged sleeves 61, both of which are fixed to the top wall of the mounting plate 1. A sliding shaft 62 is slidably installed inside the sleeve 61.

[0046] The bottom ends of the sliding shafts 62 slide through the mounting plate 1 and are fixedly connected to the top wall of the bracket 51. The top ends of the sliding shafts 62 slide through the top wall of the sleeve 61. A connecting plate 63 is fixed between the top ends of the two sliding shafts 62. A limit plate 64 is fixed on the shaft of the sliding shaft 62 located inside the sleeve 61.

[0047] The limiting plate 64 is slidably installed inside the sleeve 61, and a spring 65 is fixed between the top wall of the limiting plate 64 and the top wall of the inner cavity of the sleeve 61.

[0048] Spring 65 is sleeved on the outside of slide shaft 62.

[0049] In this embodiment, the pressing mechanism 6 ensures that the pressure roller mechanism 5 always presses against the top of the welding wire on the welding wire reel body 12, preventing wire skipping during extraction. When installing the welding wire reel body 12, the connecting plate 63 needs to be pulled upwards. The connecting plate 63 drives the bottom pressing roller 52 upwards via the sliding shaft 62, compressing the spring 65 until the welding wire reel body 12 can be smoothly fitted onto the movable rings 4 on both sides. After releasing the connecting plate 63, the pressing roller 52 will always be in contact with the surface of the outermost welding wire under the action of the spring 65, preventing wire skipping during extraction. At the same time, the rotating pressing roller 52 effectively prevents wear caused by friction between the welding wire and the pressing roller 52 during extraction.

[0050] The connecting mechanism 7 includes an L-shaped plate 71, and a movable plate 73 is slidably sleeved on one end of the horizontal plate of the L-shaped plate 71.

[0051] One end of the movable plate 73 located inside the L-shaped plate 71 is fixed with a baffle 74, and the other end of the movable plate 73 is fixedly connected to the L-shaped connecting frame 2.

[0052] A limiting groove 72 is provided in the horizontal plate of the L-shaped plate 71, and a baffle 74 is slidably installed in the limiting groove 72.

[0053] The vertical sidewall of the L-shaped plate 71 has a through mounting hole 75.

[0054] In this embodiment, the connecting mechanism 7 can adjust its length within a certain range, so that the L-shaped plate 71 on the connecting mechanism 7 can smoothly contact the mounting frame of the welding wire spool, and the anti-wire jumping device of the welding wire spool is fixed to the mounting frame of the welding wire spool by bolts and mounting holes 75.

[0055] A welding wire spool includes a welding wire spool body 12 and a welding wire spool anti-scraping device installed on the welding wire spool body 12.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
