Description

Technical Field

[0001] This invention relates to the technical field of stainless steel welding wire cleaning equipment, specifically a cleaning device for stainless steel welding wire production. Background Technology

[0002] Stainless steel welding wire, a key material for welding high-alloy steels and corrosion-resistant alloys, is widely used in manufacturing industries such as petrochemicals, nuclear power, and shipbuilding. The production process mainly includes wire rod pretreatment, multi-pass drawing, surface treatment, and winding packaging. Among these, the drawing process is crucial. Due to the high hardness and significant work hardening tendency of stainless steel, lubricants are needed during drawing to reduce friction and prevent wire breakage. However, a large amount of lubricant, metal powder, and oxide film remain on the surface of the welding wire after drawing. If not thoroughly removed, these residues will cause defects such as porosity, spatter, and cracks during welding, severely reducing weld quality and corrosion resistance. Therefore, the cleaning process becomes a core element in ensuring the performance of the welding wire.

[0003] However, most existing cleaning devices for stainless steel welding wire utilize unidirectional rotating wiping bodies. For example, a cylindrical wiping component is fitted around the circumference of the welding wire, and the inner wall of the cylindrical wiping component is equipped with bristles. The feeding of the stainless steel welding wire and the rotation of the cylindrical wiping component are used to treat the dirt on the outer circumference of the welding wire. Since the bristles cover the welding wire in a fixed and continuous spiral, when the bristles fall off after a long period of use or the bristle density is insufficient due to other reasons, axial stripe-like uncleaned areas will remain on the surface of the welding wire, resulting in dead corners and poor uniformity in cleaning the dirt on the outer circumference of the welding wire. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for the production of stainless steel welding wire, which greatly improves the uniformity of cleaning contaminants on the outer surface of the welding wire.

[0005] The technical solution of this invention is:

[0006] A cleaning device for stainless steel welding wire production includes a housing, which is cylindrical in shape. Support sleeves are embedded at the center of both end faces of the housing. The housing has an internal cavity and is a detachable, split structure, including a cover and a lower housing. The cover has a handle. Two planetary gear assemblies are spaced apart along the length of the housing. The two planetary gear assemblies are symmetrically arranged, and the gear rings of both assemblies are fixed to the inner wall of the housing. The sun gear of each planetary gear assembly serves as the output shaft. Multiple planetary gears on each assembly rotate on their own axis while revolving around the sun gear as an axis. The sun gears of the planetary gear assembly each have a channel along their central axis; a cleaning assembly is provided between the two planetary gear assemblies, the cleaning assembly including: multiple rotating rollers, each of which is connected at both ends to the gear shafts of two planetary gears at corresponding positions in the two planetary gear assemblies; each rotating roller is provided with a wiping body with a spiral structure extending along its axial direction, the welding wire passes through the channel of the two sun gears and is located between the multiple rotating rollers, and the outer side of the wiping body on each rotating roller is in close contact with the outer circumferential surface of the welding wire, the dirt on the outer circumferential surface of the welding wire is removed by the revolution and rotation of the planetary gears.

[0007] Through the combined motion of the sun gear and multiple planetary gears in the planetary gear assembly, the wiping body on the rotating roller connected between each pair of planetary gears works in conjunction with the feeding trajectory of the welding wire on the production line. This ensures that the wiping body can continuously and repeatedly treat the contaminants on the welding wire from various angles on the outer circumference of the welding wire. By combining the rotation and revolution of the planetary gears with the spiral structure of the wiping body, the movement trajectory of the wiping point relative to the welding wire becomes a complex spatial curve, achieving multi-angle and large-area cleaning coverage. This can cover the circumferential surface of the welding wire to a great extent, overcoming the dead angle problem of traditional unidirectional rotation or linear wiping, and greatly improving the uniformity of cleaning.

[0008] Furthermore, the spiral structure of the wiping body uses the outer edge of the spiral structure as the scraping edge. By designing the spiral angle to be opposite to the direction of the welding wire travel, the outer edge of the wiping body can more effectively cut into and scrape off stubborn dirt, such as oxide scale and hardened grease, attached to the surface of the welding wire.

[0009] Meanwhile, the spiral structure pushes the scraped-up dirt to the rear of the welding wire's travel direction, achieving directional removal of dirt and effectively preventing the scraped-up dirt from being carried forward by the welding wire and re-attached, greatly improving cleaning efficiency and reducing secondary pollution.

[0010] Furthermore, the wiping body includes: a clamping groove, which is formed on the outer side of the wiping body in contact with the outer peripheral surface of the welding wire along the spiral direction of the wiping body; a carrier, which is an airbag structure, embedded in the clamping groove, with one end of the carrier connected to an inflation connector; and a wiping part, which is disposed on the side of the carrier away from the bottom of the clamping groove, for wiping dirt from the outer peripheral surface of the welding wire.

[0011] The airbag structure's support body expands after inflation, allowing the raised strips on the wiping section to fit tightly and evenly against the welding wire surface. This not only facilitates adjustment of the wiping pressure but also better adapts to minor changes in the welding wire diameter or slight bending. Furthermore, the airbag structure's cushioning properties prevent the raised strips from damaging the softer welding wire surface through hard contact.

[0012] Furthermore, the wiping part includes: a fixing base connected to the wiping part; and multiple raised strips, all of which are strip-shaped structures with bristles, arranged on the fixing base along the spiral direction of the wiping body, with the multiple raised strips spaced apart along the width direction of the fixing base. The multiple spaced raised strips, as the outer edge of the spiral structure, can more concentratedly apply pressure to the outer circumference of the welding wire, deeply scraping away dirt adhering to the outer circumference of the welding wire. Simultaneously, the gaps between the multiple raised strips facilitate the discharge of the scraped dirt.

[0013] Furthermore, the spiral angle of the wiping body is opposite to the direction of the welding wire's transmission. The leading edge of the outer side of the spiral wiping body cuts into and removes dirt from the welding wire, pushing the removed dirt towards the side opposite to the direction of the welding wire's transmission, preventing the removed dirt from continuously contacting the welding wire and improving the wiping and cleaning effect on the welding wire.

[0014] Furthermore, the two planetary gear assemblies are a first planetary gear assembly and a second planetary gear assembly. The housing is divided into three chambers by the first and second planetary gear assemblies: a first chamber, a second chamber, and a third chamber. The first chamber contains a immersion solution used to soak and clean contaminants from the surface of the welding wire. The main purpose is to remove contaminants adhering to the surface of the welding wire during manufacturing, storage, or transportation, ensuring welding quality and process stability. The scrubbing assembly is located in the second chamber. Drainage pipes are provided at the bottom of the first, second, and third chambers, respectively. The three chambers are physically separated by the planetary gear assemblies, effectively preventing cross-contamination and pollution between the immersion solution, the scrubbed contaminants, and the drying gas. Each chamber is also equipped with an independent drain pipe for separately treating wastewater of different properties, such as oily wastewater and wastewater containing solid particles in the second chamber.

[0015] Furthermore, the sun gear of the first planetary gear assembly extends axially into the first cavity as an immersion section. Each meshing tooth on the immersion section has multiple grooves on its two meshing sides along its length direction, and multiple connecting slots are formed between every two adjacent meshing teeth on the circumferential surface of the immersion section. All of the multiple connecting slots are connected to the channel formed along the central axis of the immersion section.

[0016] Furthermore, the level of the immersion liquid is above the meshing teeth at the bottom of the immersion section, and a level sensor is installed in the first chamber at the height of the meshing teeth at the bottom of the immersion section. A supply pipe is connected to the first chamber. The supply pipe is equipped with a control valve, which is connected and communicates with the level sensor.

[0017] Furthermore, the connection between the connecting tank and the soaking section is provided with an inverted truncated cone structure. The inverted truncated cone structure allows the soaking liquid flowing out of the groove to flow more easily into the connecting tank and act on the outer circumferential surface of the welding wire in the channel.

[0018] Furthermore, the sun gear of the second planetary gear assembly extends into the third chamber and is connected to a drying component. The inner wall of the third chamber is provided with an arc-shaped slide rail. The drying component includes: a cylindrical outer shell, one end of which is concentrically arranged and connected to the gear shaft of the sun gear of the second planetary gear assembly; an annular slider is fitted on the circumferential surface of the cylindrical outer shell; the annular slider is slidably connected to the arc-shaped slide rail; and the shell wall of the cylindrical outer shell is provided with an installation chamber; and a spraying assembly, including: a generator, equipped with a power supply, both the power supply and the generator being located in the installation chamber as an air source; and multiple spray heads, all of which are high-pressure spray heads, located on the inner wall of the cylindrical outer shell, facing the outer circumferential surface of the welding wire, and all of the multiple spray heads being connected to the generator.

[0019] The drying unit is connected to the sun gear, allowing it to rotate synchronously with the sun gear. High-pressure jets on its inner wall spray hot or dry, clean air directly onto the welding wire surface, effectively dispersing and peeling away residual liquid films and fine water droplets. Furthermore, the jets rotate with the drying unit, performing a high-speed circular scan of the high-pressure airflow around the welding wire, achieving uninterrupted, powerful 360-degree cleaning of the wire surface, resulting in fast and thorough drying.

[0020] By embedding the generator within the mounting chamber of the cylindrical housing, the structure of the drying unit becomes more compact, reducing external pipeline connections and avoiding the influence of pipelines on the rotation of the drying unit.

[0021] Furthermore, the inner wall of the cylindrical outer shell forms a conical channel, and the radius of the conical channel gradually decreases away from the first chamber. Each spray head is arranged perpendicular to the conical channel. As the conical channel gradually narrows, the airflow velocity increases away from the inlet, reaching its maximum velocity near the outlet of the welding wire feed, resulting in the strongest impact force and ensuring the final drying effect. The spray head also emits airflow impact in an inclined manner in the opposite direction of the welding wire feed, causing the blown-away water droplets to fall in the opposite direction of the welding wire feed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention utilizes the combined motion of the sun gear and multiple planetary gears in a planetary gear assembly. This allows the wiping body on the rotating roller connected between each pair of planetary gears to coordinate with the feeding trajectory of the welding wire on the production line. This ensures that the wiping body can continuously and repeatedly treat contaminants on the welding wire from various angles on its outer circumference. The rotation and revolution of the planetary gears, combined with the spiral structure of the wiping body, create a complex spatial curve in the movement trajectory of the wiping point relative to the welding wire, achieving a wider cleaning coverage from multiple angles. This covers more cleaning points around the circumference of the welding wire, overcoming the dead-angle problem of traditional unidirectional rotation or linear wiping, and greatly improving cleaning uniformity. Furthermore, the spiral structure of the wiping body uses its outer edge as a scraping edge. The reverse design of the spiral angle and the direction of the welding wire's travel allows the outer edge of the wiping body to more effectively cut into and scrape off firmly attached contaminants, such as oxide scale and hardened grease, from the surface of the welding wire. Meanwhile, the spiral structure pushes the scraped-up dirt to the rear of the welding wire's travel direction, achieving directional removal of dirt and effectively preventing the scraped-up dirt from being carried forward by the welding wire and re-attached, greatly improving cleaning efficiency and reducing secondary pollution.

[0024] 2. Compared to existing methods that rely on multiple guide wheels to continuously change the wire's feed direction while considering wire tension, allowing the wire to pass through the immersion bath solution, this invention utilizes the rotation of the sun gear of the first planetary gear assembly. Grooves on the meshing teeth scoop up the immersion solution submerged at the bottom. The rotation of the sun gear of the first planetary gear assembly transports the scooped-up solution from the bottom to the top. The solution then automatically falls under gravity between the two meshing teeth and enters the channel through a connecting groove, acting on the circumference of the welding wire. The continuous rotation of the sun gear of the first planetary gear assembly ensures a continuous supply of immersion solution to the circumference of the welding wire. This results in a simpler structure and less impact on the welding wire. Attached Figure Description

[0039] Example

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, a cleaning device for stainless steel welding wire production includes a housing 1, two planetary gear assemblies, and a scrubbing assembly 6. The housing 1 has a cylindrical structure, with support sleeves 16 embedded at the center of both end faces. The housing 1 has an internal cavity and is a detachable, split structure. The housing 1 includes a cover 11 and a lower housing 12. The cover 11 has a handle 17. Two planetary gear assemblies are spaced apart along the length of the housing 1. The two planetary gear assemblies are symmetrically arranged, and the gear rings of both planetary gear assemblies are fixed to the inner wall of the housing 1. The sun gear of each planetary gear assembly serves as the output shaft. Multiple planetary gears on each planetary gear assembly rotate on their own axis while revolving around the sun gear on an annular slide on an annular plate. Figure 2 and Figure 4 As shown, the annular plates on the two planetary gear assemblies are a first annular plate 31 and a second annular plate 41, respectively. The first annular plate 31 has a first annular slide 311, and the second annular plate 41 has a second annular slide 411. The sun gears of both planetary gear assemblies have channels along their central axes. A scrubbing assembly 6 is provided between the two planetary gear assemblies, such as... Figure 2 , Figure 6 and Figure 8As shown, the wiping assembly 6 includes multiple rotating rollers 61, with each end of the rotating roller 61 connected to the gear shafts of two planetary gears at corresponding positions in the two planetary gear assemblies. Each rotating roller 61 is provided with a wiping body 62 with a spiral structure extending along its axial direction. The welding wire 2 passes through the channel of the two sun gears and is located between the multiple rotating rollers 61. The welding wire 2 is kept under tension by a wire feeding mechanism, which is a conventional device on existing production lines and will not be described in detail here. This ensures that the welding wire 2 is kept in the center of the channel and has a gap between it and the inner wall of the channel. The outer surface of the wiping body 62 on each rotating roller 61 is in close contact with the outer circumferential surface of the welding wire 2. The dirt on the outer circumferential surface of the welding wire 2 is removed by the revolution and rotation of the planetary gears.

[0041] Through the combined motion of the sun gear and multiple planetary gears in the planetary gear assembly, the wiping body 62 on the rotating roller 61 connected between each pair of planetary gears works in conjunction with the feeding trajectory of the welding wire 2 on the production line. This ensures that the wiping body 62 can continuously and repeatedly treat the dirt on the welding wire 2 from various angles on the outer circumference of the welding wire 2. Through the rotation and revolution of the planetary gears in conjunction with the spiral structure of the wiping body 62, the movement trajectory of the wiping point relative to the welding wire 2 is a complex spatial curve, achieving a larger angle of cleaning coverage. It can cover most of the circumference of the welding wire 2, overcoming the dead angle problem of traditional unidirectional rotation or straight-line wiping, and greatly improving the uniformity of cleaning.

[0042] Furthermore, the outer edge of the wiping body 62 serves as the scraping edge due to the spiral structure. By designing the spiral angle to be opposite to the direction of travel of the welding wire 2, the outer edge of the wiping body 62 can more effectively cut into and scrape off the stubborn dirt, such as oxide scale and hardened grease, attached to the surface of the welding wire 2.

[0043] At the same time, the spiral structure pushes the scraped dirt to the rear of the direction of the welding wire 2, realizing the directional removal of dirt. This effectively prevents the scraped dirt from being carried forward by the welding wire 2 and re-attached, greatly improving cleaning efficiency and reducing secondary pollution.

[0044] In some embodiments, such as Figure 9 As shown, the wiping body 62 includes: a clamping groove 622, a carrier 621, and a wiping part 623. The clamping groove 622 is formed along the spiral direction of the wiping body 62 on the outer side of the wiping body 62 that contacts the outer peripheral surface of the welding wire 2. The carrier 621 is an airbag structure, embedded in the clamping groove 622, and one end of the carrier 621 is connected to an air inlet connector 63. The wiping part 623 is disposed on the side of the carrier 621 away from the bottom of the clamping groove 622, and is used to wipe the dirt on the outer peripheral surface of the welding wire 2.

[0045] The carrier 621 of the airbag structure expands after inflation, allowing the wiping part 623 to fit tightly and evenly against the surface of the welding wire 2. This not only facilitates adjustment of the wiping pressure of the wiping part 623 but also makes it easier to adapt to minor changes in the diameter or slight bending of the welding wire 2. Furthermore, the cushioning properties of the airbag structure prevent the wiping part 623 from damaging the softer surface of the welding wire 2 through hard contact.

[0046] In some embodiments, such as Figure 9 As shown, the wiping part 623 includes: a fixed base and a plurality of protrusions 624, the fixed base and the wiping part 623 are connected; the plurality of protrusions 624 are arranged on the fixed base along the spiral direction of the wiping body 62, and the plurality of protrusions 624 are spaced apart along the width direction of the fixed base. The plurality of spaced protrusions 624 serve as the outer edge of the spiral structure, which can more concentratedly apply pressure to the outer peripheral surface of the welding wire 2, deeply scrape off the dirt attached to the outer peripheral surface of the welding wire 2, and at the same time use the gap between the plurality of protrusions 624 to discharge the scraped dirt.

[0047] In some embodiments, the helical angle of the wiping body 62 is opposite to the transmission direction of the welding wire 2. The leading edge of the outer side of the wiping body 62 with the helical structure cuts into and removes dirt from the welding wire 2, and pushes the removed dirt to the side opposite to the transmission direction of the welding wire 2, preventing the removed dirt from continuously contacting the welding wire 2, thereby improving the wiping and cleaning effect on the welding wire 2.

[0048] In some embodiments, such as Figure 2 As shown, the two planetary gear assemblies are: a first planetary gear assembly 3 and a second planetary gear assembly 4. The housing 1 is divided into three chambers by the first planetary gear assembly 3 and the second planetary gear assembly 4: a first chamber 13, a second chamber 14, and a third chamber 15. The first chamber 13 contains a immersion solution 134, which is used to soak and clean the surface of the welding wire 2. The main purpose is to remove contaminants that adhere to the surface of the welding wire 2 during manufacturing, storage, or transportation, ensuring welding quality and process stability. The cleaning assembly 6 is located in the second chamber 14. Drainage pipes are provided at the bottom of the first chamber 13, the second chamber 14, and the third chamber 15. The system comprises a first drain pipe 132, a second drain pipe 141, and a third drain pipe 151. Each of these three drain pipes is equipped with a solenoid valve, and all solenoid valves can be connected to a single controller for operation. The controller opens the solenoid valves on the drain pipes, allowing the liquid in the corresponding chamber to be discharged. The three chambers are physically separated by a first annular plate 31 and a second annular plate 41 of a planetary gear assembly, effectively preventing cross-contamination and pollution between the immersion liquid 134, the scrubbed dirt, and the drying gas. Each chamber also has an independent drain pipe for separately treating wastewater of different properties, such as oily wastewater and wastewater containing solid particles in the second chamber 14.

[0049] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 as well as Figure 7 As shown, the sun gear of the first planetary gear assembly 3 extends into the first chamber 13 along its axial direction, serving as the soaking section 5. One end of the soaking section 5 is rotatably connected to the support sleeve 16 at the left end. Each meshing tooth 51 on the soaking section 5 has multiple grooves 52 on its two meshing sides along its length direction, and multiple connecting grooves 53 are provided between every two adjacent meshing teeth 51 on the circumferential surface of the soaking section 5. The multiple connecting grooves 53 are all connected to the channel opened along the central axis of the soaking section 5.

[0050] The immersion liquid 134 submerged at the bottom is scooped up by the rotation of the sun gear of the first planetary gear assembly 3 through the groove 52 on the meshing teeth 51. The scooped immersion liquid 134 is transported from the bottom to the top by the rotation of the sun gear of the first planetary gear assembly 3. The immersion liquid 134 falls automatically between the two meshing teeth 51 by gravity and enters the channel through the connecting groove 53, acting on the circumferential surface of the welding wire 2. Through the continuous rotation of the sun gear of the first planetary gear assembly 3, the immersion liquid 134 is continuously applied to the circumferential surface of the welding wire 2. This not only allows the immersion liquid 134 to be evenly applied to the surface of the welding wire 2 and dissolves the surface dirt, but also has a simpler structure and less impact on the quality of the welding wire 2.

[0051] like Figure 2 As shown, the level of the immersion liquid 134 is above the meshing teeth 51 at the bottom of the immersion section 5. A level sensor 133 is installed in the first chamber 13 at the height of the meshing teeth 51 at the bottom of the immersion section 5, and a supply pipe 131 is connected to the first chamber 13. The supply pipe 131 is equipped with a control valve, which is connected to the level sensor 133 for communication, and replenishes the immersion liquid 134 in a timely manner so that the level of the immersion liquid 134 is always kept just above the meshing teeth 51 at the bottom of the immersion section 5.

[0052] In some embodiments, such as Figure 7 As shown, the connection between the connecting groove 53 and the soaking section 5 is provided with an inclined surface 531 of an inverted truncated cone structure. The inclined surface 531 of the inverted truncated cone structure allows the immersion liquid 134 flowing out of the groove 52 to flow more easily into the connecting groove 53 and act on the outer peripheral surface of the welding wire 2 in the channel.

[0053] like Figure 2 and Figure 10As shown, the sun gear of the second planetary gear assembly 4 extends into the third chamber 15 and is connected to a drying component 7. The inner wall of the third chamber 15 is provided with an arc-shaped slide rail 18. The drying component 7 includes a cylindrical outer shell and a spraying assembly. One end of the cylindrical outer shell is concentrically arranged and connected to the gear shaft of the sun gear of the second planetary gear assembly 4. An annular slider 72 is fitted on the circumferential surface of the cylindrical outer shell. The annular slider 72 is slidably connected to the arc-shaped slide rail 18. The shell wall of the cylindrical outer shell is provided with an installation chamber. The spraying assembly includes a generator and multiple spray heads 71. The generator is disposed in the installation chamber. The multiple spray heads 71 ​​are disposed on the inner wall of the cylindrical outer shell, facing the outer circumferential surface of the welding wire 2, and all of the multiple spray heads 71 ​​are connected to the generator.

[0054] The drying component 7 is connected via a sun gear extension, allowing it to rotate synchronously with the sun gear. Hot or dry, clean air is ejected through a high-pressure jet nozzle 71 on its inner wall, directly impacting the surface of the welding wire 2 and effectively dispersing and peeling away residual liquid films and fine water droplets. The jet nozzle 71 rotates with the drying component 7, performing a high-speed circular scan of the high-pressure airflow around the welding wire 2, achieving uninterrupted, powerful 360-degree sweeping of the wire 2 surface, resulting in fast and thorough drying. By embedding the generator within the mounting cavity of the cylindrical outer shell, the structure of the drying component 7 is made more compact, reducing external pipeline connections and avoiding the influence of pipelines on the rotation of the drying component 7.

[0055] like Figure 2 As shown, the inner wall of the cylindrical outer shell forms a conical channel, and the radius of the conical channel gradually decreases in the direction away from the first chamber 13. Each nozzle 71 is set perpendicular to the conical channel. As the conical channel gradually narrows, the airflow velocity increases as it moves away from the inlet, reaching its maximum velocity near the outlet of the welding wire 2 feed, resulting in the strongest impact force and ensuring the final drying effect. The nozzle 71 also emits airflow impact in an inclined manner in the opposite direction of the welding wire 2 feed, causing the blown-away water droplets to fall in the opposite direction of the welding wire 2 feed direction.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
