[0060] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0061] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The control method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0062] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first", "second", and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0063] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure is flipped, then an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Thus, the exemplary term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0064] As Figures 1 to 7 shown, an embodiment of the present disclosure provides a wire feeding device for automatic welding of water wall boiler tubes, including: a mounting mechanism 1, an inner support mechanism 2, a wire spool 3, a wire feeding mechanism 5, and a wire guiding mechanism 6. Specifically, the inner support mechanism 2 includes: a driving motor 201, an inner support tube 202, a linkage rod 210, and a clamping assembly. The driving motor 201 is fixedly disposed on the mounting mechanism 1, the driving motor 201 is drivingly connected to the inner support tube 202, the linkage rod 210 is movably disposed through the inner support tube 202, the inner support tube 202 and the linkage rod 210 are respectively connected to the clamping assembly, the wire spool 3 is sleeved on the inner support tube 202, the clamping assembly is disposed inside the wire spool 3, the clamping assembly has an extended state and a contracted state. When the clamping assembly is in the extended state, the inner support mechanism 2 is clamped to the wire spool 3; when the clamping assembly is in the contracted state, the inner support mechanism 2 and the wire spool 3 can move relative to each other. The wire feeding mechanism 5 is disposed at one end of the wire spool 3, and the wire guiding mechanism 6 is disposed close to the wire feeding mechanism 5.

[0065] The wire feeding device for automatic welding of water wall boiler tubes according to the embodiments of the present disclosure includes a mounting mechanism 1, an inner support mechanism 2, a wire reel 3, a wire feeding mechanism 5, and a wire guiding mechanism 6. The inner support mechanism 2 is installed on the mounting mechanism 1, and the inner support mechanism 2 is drivingly connected to the wire reel 3. The wire feeding mechanism 5 and the wire guiding mechanism 6 are arranged in sequence along the transmission direction of the wire. The inner support mechanism 2 drives the wire reel 3 to rotate to convey the wire on the wire reel 3 to the feeding mechanism, and the wire feeding mechanism 5 conveys the wire to the wire guiding mechanism 6, thereby realizing the conveyance of the wire. Specifically, the driving motor 201 of the inner support structure is drivingly connected to the inner support tube 202. The inner support tube 202 is sleeved on the linkage rod 210, and the linkage rod 210 can move relative to the inner support rod along the extension direction of the inner support tube 202. The wire reel 3 is sleeved on the inner support tube 202. The clamping assembly is respectively connected to the inner support tube 202 and the linkage rod 210, and the clamping assembly is arranged inside the wire reel 3. When the clamping assembly is in the extended state, the clamping assembly abuts against the wire reel 3, that is, the linkage rod 210 and the inner support tube 202 are connected to the wire reel 3 through the clamping assembly, thereby realizing the connection between the inner support mechanism 2 and the wire reel 3; when the clamping assembly is in the contracted state, the clamping assembly can move relative to the wire reel 3, that is, the clamping assembly does not abut against the wire reel 3, that is, the linkage rod 210 and the inner support tube 202 are not connected to the wire reel 3, and the wire reel 3 can be separated from the inner support structure by moving the wire reel 3. By providing a detachable inner support mechanism 2 and wire reel 3, the quick disassembly of the inner support mechanism 2 and the wire reel 3 can be realized, the replacement time of the wire reel 3 can be shortened, thereby improving the replacement rate of the wire reel 3. At the same time, the downtime for replacing the wire reel 3 is reduced, and the efficiency of the overall welding operation is improved. In addition, in continuous welding tasks, improving the efficiency of switching the wire reel 3 can ensure the coherence of the welding process and avoid causing fluctuations in welding quality.

[0066] As Figure 5 shown, in some embodiments of the present disclosure, the clamping assembly includes: at least two elastic pieces 206 and at least two elastic rods 207. Specifically, the number of elastic pieces 206 is the same as the number of elastic rods 207, and the elastic pieces 206 and the elastic rods 207 are arranged in one-to-one correspondence. Among them, at least two elastic pieces 206 are arranged at equal intervals along the circumferential direction of the inner support tube 202, and at least two elastic rods 207 are arranged at equal intervals along the circumferential direction of the inner support tube 202. Specifically, the elastic piece 206 has a first end and a second end arranged oppositely. The first end of the elastic piece 206 is fixedly connected to the outer wall of the inner support tube 202, and the second end of the elastic piece 206 extends towards the direction of the wire reel 3. Both ends of the elastic rod 207 are respectively connected to the linkage rod 210 and the second end of the elastic piece 206, and the elastic rod 207 passes through the inner support tube 202 along the radial direction of the inner support tube 202.

[0067] When the clamping component is in the extended state, the second end of the elastic piece 206 abuts against the inner side of the wire spool 3; when the clamping component is in the contracted state, the second end of the elastic piece 206 can move relative to the wire spool 3. Process of the clamping component switching from the extended state to the contracted state: The second end of the elastic piece 206 abuts against the inner side of the wire spool 3, move the linkage rod 210 along the extending direction of the inner support tube 202 to make the linkage rod 210 move forward relative to the inner support tube 202. When the linkage rod 210 moves, the linkage rod 210 drives the first end of the elastic rod 207 to move forward, and the second end of the elastic rod 207 moves in the direction away from the wire spool 3, so that the second end of the elastic piece 206 connected to the second end of the elastic rod 207 is separated from the wire spool 3. At this time, the clamping component switches from the extended state to the contracted state, and this process is also the disassembly process of the inner support mechanism 2 and the wire spool 3. Process of the clamping component switching from the contracted state to the extended state: The second end of the elastic piece 206 does not abut against the inner side of the wire spool 3, move the linkage rod 210 along the extending direction of the inner support tube 202 to make the linkage rod 210 move backward relative to the inner support tube 202. When the linkage rod 210 moves, the linkage rod 210 drives the first end of the elastic rod 207 to move backward, and the second end of the elastic rod 207 moves in the direction towards the wire spool 3, so that the second end of the elastic piece 206 connected to the second end of the elastic rod 207 abuts against the wire spool 3. At this time, the clamping component switches from the contracted state to the extended state, and this process is also the installation process of the inner support mechanism 2 and the wire spool 3. In this embodiment, since the extending direction from the first end to the second end of the elastic piece 206 includes the radial extension from the inner support tube 202 to the wire spool 3 and the extension from the direction away from the driving motor 201 to the direction close to the driving motor 201, the forward movement of the linkage rod 210 refers to the movement in the direction towards the driving motor 201, and the backward movement of the linkage rod 210 refers to the movement in the direction away from the driving motor 201.

[0068] As Figure 4 and Figure 5 shown, in some embodiments of the present disclosure, the inner support mechanism 2 further includes: a fixing ring 205, a connecting seat 209 and at least two guiding rings 208. Among them, the fixing ring 205 is fixedly sleeved on the inner support tube 202, the first end of the elastic piece 206 is fixedly connected to the fixing ring 205, and the second end of the elastic piece 206 extends towards the wire spool 3. The connecting seat 209 is fixedly sleeved on the linkage rod 210, the first end of the elastic rod 207 far from the wire spool 3 is connected to the connecting seat 209, and the second end of the elastic rod 207 close to the wire spool 3 is connected to the second end of the elastic piece 206. The guiding ring 208 is radially penetrated through the inner support tube 202 along the inner support tube 202, and the elastic rod 207 is penetrated through the guiding ring 208 to guide the elastic rod 207 through the guiding ring 208.

[0069] Specifically, the number of guiding rings 208 is the same as the number of elastic rods 207, and the guiding rings 208 and the elastic rods 207 are arranged in one-to-one correspondence. In this embodiment, the number of elastic pieces 206, elastic rods 207 and guiding rings 208 is the same, and the number can be two. The two elastic pieces 206 are relatively arranged inside the wire reel 3, so as to enable the connection between the wire reel 3 and the linkage rod 210. The number of elastic pieces 206 can also be more than two. The more than two elastic pieces 206 are spaced and evenly distributed along the circumferential direction of the inner support rod, which can further improve the firmness of the connection between the wire reel 3 and the linkage rod 210. On the basis of ensuring the connection reliability between the wire reel 3 and the linkage rod 210, in order to simplify the manufacturing process of the device, in this embodiment, four elastic pieces 206, four elastic rods 207 and four guiding rings 208 are taken as the preferred scheme.

[0070] Furthermore, the elastic rod 207 is a thin steel wire. The thin steel wire has a certain elasticity and can produce a movable elastic deformation. At the same time, the thin steel wire has a certain rigidity and is not easily damaged.

[0071] As Figure 4 shown, in some embodiments of the present disclosure, the inner support mechanism 2 further includes: two positioning discs 203. The two positioning discs 203 are respectively arranged at both ends of the inner support tube 202. Both ends of the wire reel 3 are respectively in contact with the two positioning discs 203, and the two positioning discs 203 are used to limit the position of the wire reel 3. Specifically, the first positioning disc 203 is arranged at the end of the inner support tube 202 where the driving motor 201 is provided. One side of the first positioning disc 203 is in contact with the wire reel 3, and the other side of the first positioning disc 203 is in contact with one side of the short board of the L-shaped mounting bracket 101. The other side of the short board of the L-shaped mounting bracket 101 is fixedly connected to the driving connection. The second positioning disc 203 is arranged at the end of the inner support tube 202 far from the driving motor 201. One side of the second positioning disc 203 is in contact with the wire reel 3, and the other side of the second positioning disc 203 is in contact with the limiting mechanism 4. The two positioning discs 203 and the wire reel 3 are both arranged between the limiting mechanism 4 and the short board of the L-shaped mounting bracket 101, that is, the limiting mechanism 4 and the L-shaped mounting bracket 101 limit the two positioning discs 203 and the wire reel 3.

[0072] As Figure 4 shown, the inner support mechanism 2 further includes: a side cover plate 211. The side cover plate 211 is sleeved on the linkage rod 210 and the side cover plate 211 is arranged at the end of the inner support tube 202 far from the driving motor 201. The side cover plate 211 and the second positioning disc 203 are respectively located on opposite sides of the limiting mechanism 4, and the side cover plate 211 and the second positioning disc 203 are respectively in contact with the limiting mechanism 4, so as to limit the inner support tube 202 through the side cover plate 211.

[0073] As Figure 3 and Figure 4As shown, the inner support mechanism 2 further includes: a pressing handle 204, which is provided at the end of the linkage rod 210 away from the driving connection, so as to realize the relative movement of the linkage rod 210 and the inner support tube 202 by moving the pressing handle 204, thereby realizing the installation and disassembly of the wire reel 3 and the inner support mechanism 2.

[0074] In some embodiments of the present disclosure, the wire reel 3 includes: a cylinder body 301 and a limiting ring 302. The cylinder body 301 is sleeved on the inner support tube 202, and both ends of the cylinder body 301 are respectively in contact with the two positioning discs 203 to limit the cylinder body 301 through the two positioning discs 203. The limiting ring 302 is internally connected to the cylinder body 301, that is, the circumferential outer wall of the limiting ring 302 is connected to the circumferential inner wall of the cylinder body 301, and the disassembly of the wire reel 3 and the inner support mechanism 2 is realized through the cooperation of the limiting ring 302 and the clamping assembly. Specifically, when the clamping assembly is in the extended state, the second end of the elastic piece 206 of the clamping assembly abuts against the limiting ring 302; when the clamping assembly is in the contracted state, the second end of the elastic piece 206 of the clamping assembly can move relative to the limiting ring 302. During the process of installing the wire reel 3 on the inner support tube 202, the wire reel 3 is moved from the end of the inner support tube 202 away from the driving motor 201 towards the driving motor 201. The cylinder body 301 of the wire reel 3 contacts the second end of the elastic piece 206. As the wire reel 3 moves, the limiting ring 302 of the wire reel 3 abuts against the second end of the elastic piece 206, thereby realizing the connection between the wire reel 3 and the inner support mechanism 2.

[0075] In some embodiments of the present disclosure, the installation mechanism 1 includes: an installation frame 101, a fixed seat 102, and a fixing bolt 103. Specifically, the installation frame 101 is an L-shaped structure, the driving motor 201 is fixedly connected to the short board of the L-shaped structure, and the driving motor 201 and the first positioning disc 203 are respectively located on opposite sides of the short board of the L-shaped structure. The long board of the L-shaped structure is connected to the fixed seat 102, and the fixed seat 102 is provided with an installation groove. The fixing bolt 103 passes through the installation groove and is connected to other fixed settings through the fixing bolt 103.

[0076] Specifically, the number of the fixed seats 102 is the same as that of the fixing bolts 103, and the fixing bolts 103 are arranged in one-to-one correspondence with the fixed seats 102. At least one fixed seat 102 is provided. In this embodiment, the number of the fixed seats 102 is four, two of which are arranged on the upper side of the long board of the L-shaped structure, and the remaining two fixed seats 102 are arranged on the lower side of the long board of the L-shaped structure. The cooperation of the four fixed seats 102 and the four fixing bolts 103 ensures the installation firmness of the installation mechanism 1.
