Description

Technical Field

[0001] This utility model relates to the field of flux-cored welding wire technology, and in particular to a surface cleaning device for flux-cored welding wire. Background Technology

[0002] During production, drawing, and storage, flux-cored welding wires are prone to accumulating contaminants such as oil, dust, oxides, and drawing lubricants. If these contaminants are not effectively removed, they can easily lead to welding defects such as unstable arc, increased spatter, porosity, and slag inclusions during subsequent welding, severely affecting weld quality and joint performance. Therefore, surface cleaning of flux-cored welding wires is a crucial step in ensuring welding quality.

[0003] Currently, common cleaning methods mainly include mechanical scrubbing with wire brushes and solvent cleaning. However, existing technologies mostly use single or simple combinations of cleaning methods, which have obvious drawbacks: for example, steel brush cleaning alone is insufficient to remove stubborn dirt from crevices, resulting in incomplete cleaning; simple solvent or ultrasonic cleaning lacks effective liquid film removal and drying measures, which can easily cause moisture or cleaning agent residue, leading to secondary pollution. Utility Model Content

[0004] This utility model provides a surface cleaning device for flux-cored welding wire, including a frame. Along the travel path of the flux-cored welding wire, the frame is sequentially equipped with a multi-stage brush assembly for preliminary wiping of the flux-cored welding wire, a composite cleaning unit assembly for solvent spraying and ultrasonic cavitation cleaning of the surface of the flux-cored welding wire, an elastic scraper assembly for scraping off residual liquid film and loose dirt on the surface, and a hot air drying assembly. A feeding roller and a winding roller are rotatably arranged at both ends of the frame.

[0005] Preferably, the multi-stage brush assembly includes a first steel brush and a second steel brush arranged side by side along the direction of travel of the flux-cored wire. The first steel brush and the second steel brush are rotatably mounted on a support plate. The first steel brush and the second steel brush are both driven by independent motors, and the rotation directions of the first steel brush and the second steel brush are opposite, forming a bidirectional friction cleaning of the surface of the flux-cored wire.

[0006] Preferably, the composite cleaning assembly includes a cleaning chamber fixed to the upper end of the frame, the cleaning chamber is filled with cleaning fluid, an ultrasonic generator is installed on the side wall of the cleaning chamber, and perforations for flux-cored welding wire to pass through are provided on both sides of the cleaning chamber.

[0007] Preferably, the cleaning chamber is equipped with a spray head, which is connected to a delivery pump via a cleaning fluid supply pipeline. The delivery pump draws cleaning fluid from the cleaning fluid tank, and the drain outlet at the lower end of the cleaning chamber is connected to the inlet of the sewage tank via a pipeline.

[0008] Preferably, a sealing sleeve is snapped into the perforation, and an elastic sealing ring is provided in the through hole in the middle of the sealing sleeve.

[0009] Preferably, the elastic scraper assembly includes a blade holder, the upper end of which is fixed inside an extended shell on one side of the cleaning chamber, and a V-shaped blade is movably disposed at the lower end of the blade holder. The V-shaped opening of the blade faces the flux-cored wire, and the cutting edges of its two wings lightly press against the surface of the flux-cored wire.

[0010] Preferably, hollow sleeves are fixedly provided on both sides of the tool holder, and a slide rod is slidably provided inside the hollow sleeve. One end of the slide rod passes through the lower side of the tool holder and both sides of the blade.

[0014] This utility model provides a flux-cored wire surface cleaning device, which, compared with the prior art, offers the following advantages:

[0015] 1. This utility model breaks through the limitations of traditional single cleaning methods by using a progressive cleaning process consisting of a multi-stage brush assembly, a composite cleaning assembly, an elastic scraper assembly, and a hot air drying assembly. First, the surface of the flux-cored welding wire is subjected to bidirectional friction by multi-stage counter-rotating steel brushes to achieve preliminary wiping and mechanical decontamination. Then, it enters the composite cleaning unit, where the cleaning fluid spraying and ultrasonic cavitation effect are combined in the cleaning chamber. The powerful penetrating force and micro-jet action of ultrasound are used to penetrate deep into the micropores on the surface of the welding wire and the gaps in the flux core, effectively removing stubborn oil stains, oxides, and residual lubricants, thereby improving the depth and uniformity of cleaning.

[0016] 2. After wet cleaning, the device is equipped with a V-shaped elastic scraper assembly to promptly scrape off the residual liquid film and loosened dirt on the surface of the welding wire, effectively preventing contaminants from re-attaching or forming residual stains after moisture evaporation. Subsequently, the device is swept by oblique hot air through a hot air drying assembly to quickly and thoroughly remove surface moisture, ensuring that the welding wire is dry and clean. This not only avoids secondary pollution but also forms a complete cleaning closed loop, improving the surface cleanliness and processing consistency of the flux-cored welding wire.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-8 This utility model provides a flux-cored welding wire surface cleaning device, including a frame 1, which serves as the supporting foundation for the entire equipment. A feeding roller 2 and a winding roller 27 are rotatably installed at both ends of the frame 1 to carry the flux-cored welding wire roll to be cleaned and to realize continuous automatic feeding and discharging.

[0030] refer to Figure 3 As shown, a support frame 3 is symmetrically arranged on the frame 1 near the feeding roller 2. A vertical adjustment groove 4 is opened at the upper end of the support frame 3. A slider 5 is slidably fitted in the adjustment groove 4. A tension roller 7 is fixedly connected between the two sliders 5 to adjust the running tension of the flux-cored welding wire.

[0031] The top of the adjusting groove 4 is threaded with a screw 6, and the lower end of the screw 6 is rotatably connected to the slider 5. By rotating the screw 6, the slider 5 can be driven to move up and down along the adjusting groove 4, thereby adjusting the height of the tension roller 7 and achieving precise control of the tension of the flux-cored welding wire.

[0032] A pressure roller 8 is also provided on the frame 1 near the support frame 3, which is used to initially press and guide the flux-cored wire into the subsequent cleaning unit. The height of the pressure roller 8 is adapted to the height of the perforation 131 of the cleaning chamber 13 to ensure that the flux-cored wire passes through smoothly.

[0033] Along the transmission path of the flux-cored welding wire on the frame 1, a multi-stage brush assembly, a composite cleaning unit assembly, an elastic scraper assembly, and a hot air drying assembly are sequentially arranged to form a complete progressive cleaning process.

[0034] like Figures 1 to 3 As shown, the multi-stage brush assembly includes a support plate 9, which is fixed on the frame 1. Steel brush 10 and steel brush 2 11 are mounted side by side and rotated on the support plate 9. They are arranged sequentially along the direction of travel of the flux-cored wire. Steel brush 10 and steel brush 2 11 are driven to rotate by independent drive motors in opposite directions, forming a bidirectional friction action on the surface of the flux-cored wire, realizing the initial wiping and mechanical removal of surface dust, slight oxide layer and attachments.

[0035] like Figure 4 and Figure 5 As shown, the composite cleaning unit assembly includes a cleaning chamber 13 fixed to the upper end of the frame 1. The cleaning chamber 13 is filled with cleaning fluid for wet cleaning of flux-cored wire. An ultrasonic generator 14 is installed on the outer side wall of the cleaning chamber 13. The high-frequency vibration generated by the generator is transmitted into the cleaning fluid through the chamber wall, forming a strong cavitation effect that can penetrate into the micropores and flux gaps on the surface of the flux-cored wire, effectively removing stubborn oil and residues.

[0036] like Figure 8As shown, the cleaning chamber 13 has symmetrical perforations 131 on both sides for the flux-cored welding wire to pass through and out. To prevent the cleaning fluid from leaking, a sealing sleeve 132 is snapped into the perforation 131. An elastic sealing ring is provided in the through hole in the middle of the sealing sleeve 132, which can both seal and allow the welding wire to pass through smoothly.

[0037] A spray head 16 is installed inside the cleaning chamber 13. The spray head 16 is connected to the delivery pump 17 through the cleaning fluid supply pipeline. The delivery pump 17 draws cleaning fluid from the cleaning fluid tank 18 and sprays it evenly onto the surface of the flux-cored welding wire through the spray head 16 to enhance the cleaning effect. A drain port is provided at the bottom of the cleaning chamber 13 and is connected to the inlet of the sewage tank 15 through a pipeline to facilitate the periodic discharge and replacement of the cleaning fluid.

[0038] like Figure 5 As shown, an extension shell 19 is connected to the discharge side of the cleaning chamber 13. An elastic scraper assembly is disposed inside the extension shell 19. The elastic scraper assembly includes a blade holder 20 fixed inside the extension shell 19. A V-shaped blade 21 is movably connected to the lower end of the blade holder 20. The V-shaped opening faces the flux-cored wire, and the cutting edges of its two wings lightly press against the surface of the wire to scrape off the residual liquid film and loosened dirt after cleaning, preventing contaminants from re-adhering during the drying process.

[0039] To ensure constant scraping pressure and adapt to welding wires of different diameters, such as Figure 6 and Figure 7 As shown, hollow sleeves 22 are provided on both sides of the tool holder 20. A slide rod 23 is slidably arranged inside the hollow sleeve 22. The lower end of the slide rod 23 is connected to both sides of the V-shaped blade 21. A spring 24 is provided inside the hollow sleeve 22. One end of the spring 24 is connected to the slide rod 23 to provide elastic preload, so that the blade 21 always maintains good contact with the surface of the welding wire.

[0040] A hot air drying assembly, including a hot air nozzle 25, is fixedly installed at the discharge end of the extension shell 19. The hot air nozzle 25 is connected to an external hot air generator 26 through a pipe. The air outlet direction of the hot air nozzle 25 forms an acute angle with the travel direction of the flux-cored welding wire, forming an oblique blowing airflow, which can efficiently and evenly dry the surface moisture of the welding wire, ensuring that the welding wire is dry and clean after cleaning.

[0041] To prevent impurities and liquid drips generated during the cleaning process from contaminating the environment or equipment, collection plates 12 are provided on the underside of both the support plate 9 and the extension shell 19. The collection plates 12 are used to collect solid impurities brushed down by the steel brush 10 and steel brush 21, as well as the dirty liquid scraped off by the V-shaped blade 21, so as to facilitate centralized cleaning and keep the equipment clean.

[0042] In summary, during operation, the flux-cored welding wire is drawn out from the feed roller 2, guided by the tension roller 7 and the pressure roller 8, and first passes through the multi-stage brush assembly. Under the reverse rotation friction of steel brush 10 and steel brush 21, it completes the initial wiping. Then it enters the cleaning chamber 13, where it undergoes deep cleaning under the combined action of cleaning liquid spraying and ultrasonic cavitation. After wet cleaning, the welding wire passes through the sealing sleeve 132 and leaves the cleaning chamber 13. Immediately, the surface liquid film and loose dirt are scraped off by the V-shaped blade 21. Then, it is quickly dried under the action of the inclined hot air blower 25, and finally, it is wound into a roll by the take-up roller 27.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
