Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically a coating device for flux. Background Technology

[0002] Flux is a chemical substance in the welding process that helps and promotes the welding process and prevents oxidation reactions. It helps the solder better wet the surface of the workpiece and form a strong solder joint.

[0003] During the production of welding wire, flux is applied to remove the oxide layer, lower the melting point, and improve lubricity. This is usually done by immersing the wire in flux. However, uneven application can occur. Applying too much flux can cause it to accumulate on the welding wire, resulting in dripping and significant waste. Applying too little flux can affect subsequent production processes. Utility Model Content

[0004] The technical problem to be solved by this invention is that existing fluxes generally do not achieve uniform coating when applied to welding wire.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The present invention proposes a flux coating device, including a device housing and an immersion tank installed inside. The device housing has a wire inlet hole and a wire outlet hole correspondingly provided on the lower side wall of one side wall and the upper side wall of the other side wall. A first guide roller is rotatably provided inside the device housing between the wire inlet hole and the immersion tank. A second guide roller is rotatably provided inside the device housing at the position of the wire outlet hole. The two second guide rollers are parallel to each other and located on the same horizontal plane. An immersion roller is provided inside the immersion tank. An immersion wheel is rotatably provided on the immersion roller. A limiting ring groove is provided on the immersion wheel, and an immersion ring is provided on the limiting ring groove.

[0006] Preferred technical solution 1: The outer shell of the device is further provided with an oil scraping assembly between the two sets of second guide rollers. The oil scraping assembly includes a support plate and a recovery bin installed under the support plate. The support plate is C-shaped. The bottom and top walls of the support plate are staggered with scrapers. The scrapers are provided with corresponding arc-shaped grooves. The support plate is also provided with a collection groove, which is connected to the recovery bin. The bottom of the recovery bin is provided with a discharge pipe, and the bottom of the discharge pipe extends into the immersion tank.

[0007] Preferred technical solution 2: A filter tube is provided on the outer wall of the device housing at the position corresponding to the wire inlet hole, and an air pump is provided on the outer wall of the device housing, and the air pump and the filter tube are connected by a flexible hose.

[0008] Preferred technical solution 3: The outer shell of the device is provided with two sets of guide frames on one side of the wire inlet hole, and outer guide wheels are rotatably provided on the opposite walls of the two sets of guide frames.

[0009] Preferred technical solution four: The impregnation ring is made of sponge material.

[0010] Preferred technical solution five: The front of the device housing is provided with an inspection door and an observation window is provided on the inspection door.

[0011] Preferred technical solution six: The front of the device housing is provided with an oil replenishment pipe and the oil replenishment pipe is connected to the internal immersion tank.

[0012] The flux coating device proposed in this utility model has the following beneficial effects achieved by adopting the above structure:

[0013] (1) The welding wire enters through the wire inlet hole, and is wetted with flux by the cooperation of the first guide roller and the immersion box. Then it is discharged through the second guide roller and the wire outlet hole. After the welding wire is wetted, it is conveyed vertically upward so that the flux can drip quickly into the immersion box under gravity. At the same time, the excess lubricant on the surface of the welding wire is scraped off and recycled by the scrapers set up in a cross shape.

[0014] (2) The filter tube and air pump are set up to clean the surface of the welding wire with high pressure gas before wetting, thereby reducing the contamination of the flux. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A flux coating device includes a device housing 1 and an immersion tank 2 installed inside. A wire inlet hole 3 and a wire outlet hole 4 are provided on the lower side wall of one side wall and the upper side wall of the other side wall, respectively. A first guide roller 5 is rotatably arranged between the wire inlet hole 3 and the immersion tank 2 inside the device housing 1. A second guide roller 6 is rotatably arranged opposite to the wire outlet hole 4 inside the device housing 1. The two second guide rollers 6 are parallel to each other and located on the same horizontal plane. An immersion roller 7 is provided inside the immersion tank 2. An immersion wheel 8 is rotatably arranged on the immersion roller. A limiting ring groove 9 is provided on the immersion wheel 8, and an immersion ring 10 is provided on the limiting ring groove 9. The immersion ring 10 is made of sponge material, which has a good wrapping and wetting effect on the welding wire. One set of second guide rollers 6 is located directly above the immersion roller 7. An inspection door 23 is provided at the front of the device housing 1, and an observation window 24 is provided on the inspection door 23. An oil replenishment pipe 25 is provided at the front of the device housing 1 and is connected to the immersion tank 2 inside.

[0026] Example 2

[0027] Based on Example 1, such as Figure 4As shown, an oil scraping assembly 11 is also provided on the outer shell 1 of the device between the two sets of second guide rollers 6. The oil scraping assembly 11 includes a support plate 12 and a recovery chamber 13 installed under the support plate 12. The support plate 12 is C-shaped. Scrapers 14 are alternately arranged on the bottom and top walls of the inner wall of the support plate 12. Arc grooves 15 are provided on the scrapers 14. A collection trough 16 is also provided on the support plate 12 and the collection trough 16 is connected to the recovery chamber 13. The collection trough 16 is located between two adjacent sets of scrapers 14. A discharge pipe 17 is provided at the bottom of the recovery chamber 13. The bottom of the discharge pipe 17 extends into the interior of the immersion tank 2.

[0028] like Figure 1 and Figure 5 As shown, a filter tube 18 is provided on the outer wall of the device housing 1 at a position corresponding to the inlet hole 3. An air pump 19 is provided on the outer wall of the device housing 1, and the air pump 19 is connected to the filter tube 18 through a flexible hose 20. The diameter of the inlet of the filter tube 18 is larger than the diameter of the outlet. Two sets of guide frames 21 are provided on one side of the device housing 1 near the inlet hole 3, and outer guide wheels 22 are rotatably mounted on the opposite walls of the two sets of guide frames 21.

[0029] In practical use, the outer guide roller 22 guides the welding wire entering the device from the outside, making it level with the wire inlet hole 3. One end of the welding wire passes through the filter tube 18 and enters the outer casing 1 of the device through the wire inlet hole 3. The welding wire is guided by the upper end of the first guide roller 5 and wetted in flux in cooperation with the wetting roller 8. The wetting roller 8 has a sponge-material wetting ring 10 inside, which has a good wrapping and wetting effect on the welding wire. Then the welding wire is transported upward at 90 degrees and then horizontally guided by two sets of second guide rollers 6 and scraped. The scraper 14, which is arranged vertically in the oil assembly 11, passes horizontally through the wire and is discharged from the wire outlet 4. After wetting, the vertically arranged travel path causes the excess flux to slide down by gravity and flow back into the wetting tank 2. The scraper 14, which is arranged vertically, further scrapes off the uneven flux on the surface of the welding wire and recovers it to the recovery bin 13. It then flows back into the wetting tank 2 through the discharge pipe 17. The filter pipe 18 and the air pump 19 work together to blow away the dust and impurities on the surface of the welding wire before it enters the outer shell 1 of the device.
