[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-4 A dual-fluid spray gun with a gas-liquid mixing ratio fine-tuning function includes an air pipe 1 and a liquid pipe 2, and a fine-tuning mechanism 3. The fine-tuning mechanism 3 includes a perforated frame 31 fixedly connected to the inner wall of the air pipe 1 and the liquid pipe 2. A perforated disk 32 is rotatably connected to the inner wall of the perforated frame 31. A first bevel gear 33 is fixedly connected to the bottom end of the perforated disk 32. A second bevel gear 34 is meshed with the bottom end of the first bevel gear 33. A long rod 35 is fixedly connected to one end of the second bevel gear 34. A magnetic block 37 is fixedly connected to the upper surface of the long rod 35. Magnetic rings 36 are fixedly connected to the surfaces of both the air pipe 1 and the liquid pipe 2. The magnetic block 37 and the magnetic ring 36 attract each other with opposite poles. Both the perforated frame 31 and the perforated disk 32 are made of silicone rubber.

[0031] The hollowed-out disk 32 has a first through hole distributed in a ring at its end, and the hollowed-out frame 31 has a second through hole distributed in a ring at its end. The first through hole and the second through hole are connected. The end of the magnetic block 37 contacts the inner surface of the magnetic ring 36. The lower end of the surface of the air pipe 1 is fixedly connected to the dual-fluid spray gun, and the lower end of the surface of the liquid pipe 2 is fixedly connected to the inner wall of the dual-fluid spray gun. The air pipe 1, the liquid pipe 2 and the dual-fluid spray gun are all stainless steel components. The air pipe 1 and the liquid pipe 2 are respectively connected to the corresponding pipe threads.

[0032] In this embodiment of the utility model, when coating metal products, the long rod 35 on the air pipe 1 is rotated. The rotation of the long rod 35 causes the magnetic block 37 to rotate on the inner surface of the magnetic ring 36. Because the opposite poles of the magnetic block 37 and the magnetic ring 36 attract each other, the resistance to the rotation of the long rod 35 increases, causing the long rod 35 to rotate slowly. The slow rotation of the long rod 35 causes the second bevel gear 34 to rotate slowly. Since the gear diameter of the second bevel gear 34 is smaller than the gear diameter of the first bevel gear 33, the specific gear diameter ratio can be selected according to actual needs. The rotation of the second bevel gear 34 causes the first bevel gear 33 to rotate slowly. The slow rotation of the first bevel gear 33 causes the hollow disk 32 to rotate slowly within the hollow frame 31, thereby fine-tuning the opening range of the first through hole and the second through hole, thus fine-tuning the unobstructed flow inside the air pipe 1.

[0033] First, manually turn on the compressor. The compressor compresses the outside gas and flows it into the gas pipe 1 through the corresponding pipe. The gas inside the gas pipe 1 flows into the dual-fluid spray gun through the open second and first through holes, allowing the gas to flow inside the dual-fluid spray gun. Then, manually turn on the liquid pump. The liquid pump draws the paint liquid and delivers it to the liquid pipe 2 through the corresponding pipe. The paint liquid flowing inside the liquid pipe 2 flows into the dual-fluid spray gun through the open second and first through holes, allowing the gas and liquid to meet in the mixing chamber inside the spray gun. The high-speed airflow impacts the liquid, breaking it into fine droplets. After forming a spray, it is sprayed out from the nozzle of the dual-fluid spray gun, thus uniformly coating the metal products.

[0034] After use, promptly clean the inside of the dual-fluid spray gun and the nozzle with a suitable solvent to remove any residual liquid and impurities, preventing clogging of the nozzle and corrosion of the spray gun components. During cleaning, ensure that all channels are cleaned. You can achieve a thorough cleaning by spraying the cleaning solvent multiple times.

[0035] In this embodiment of the utility model, the magnetic block 37 and the magnetic ring 36 cooperate with each other, thereby increasing the resistance to the rotation of the long rod 35. The second bevel gear 34 and the first bevel gear 33 cooperate with each other, so that the hollow disk 32 rotates slowly within the hollow frame 31. This allows for fine adjustment of the open range inside the air pipe 1 or the liquid pipe 2, thereby ensuring the uniformity of the spray from the dual-fluid spray gun and ensuring the spraying effect of the dual-fluid spray gun.

[0036] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of this utility model, mounting blocks 38 are fixedly connected to the surfaces of both the air tube 1 and the liquid tube 2. Anti-slip blocks 39 are slidably connected to the inner wall of the mounting blocks 38. The lower end of the anti-slip block 39 is engaged with the surface of the long rod 35. A spring 310 is fixedly connected to the end of the mounting blocks 38, and the other end of the spring 310 is fixedly connected to the end of the anti-slip block 39. A moving block 311 is fixedly connected to the surface of the anti-slip block 39. A ring-shaped soft pad 312, a rubber component, is fixedly connected to the surface of the long rod 35. The anti-slip block 39 is also a rubber component.

[0037] In this embodiment of the utility model, pulling the two moving blocks 311 away from each other causes the two anti-slip blocks 39 to move away from each other, thereby releasing the lock on the long rod 35.

[0038] In this embodiment of the utility model, the spring 310 pushes the anti-slider 39 to move and abut against the surface of the long rod 35, thereby locking the long rod 35 and ensuring that the hollow plate 32 is stably located inside the hollow frame 31. This ensures the stability of the fine adjustment of the open part inside the air pipe 1 or liquid pipe 2, and ensures the spraying effect of the dual-fluid spray gun.

[0039] In some embodiments, such as Figure 3 As shown, in a preferred embodiment of this utility model, sealing frames 316 are embedded in the surfaces of both the air tube 1 and the liquid tube 2. Tempered glass is fixedly connected to the inner wall of the sealing frame 316. The upper end of the inner wall of the hollow frame 31 is recessed into a funnel shape, and a protective sleeve 313 is fixedly connected to the bottom end of the hollow frame 31. The first bevel gear 33 and the second bevel gear 34 are both located inside the protective sleeve 313. Sealing bearings 314 are fixedly connected to the inner walls of the air tube 1, the liquid tube 2, and the protective sleeve 313. The surface of the long rod 35 is fixedly connected to the inner edge of the sealing bearing 314. A fixing frame 315 is fixedly connected to the surfaces of both the air tube 1 and the liquid tube 2. The surfaces of the magnetic block 37 and the magnetic ring 36 are both located inside the fixing frame 315. The sealing frame 316 is a silicone rubber component.

[0040] Sealed bearing 314 is a bearing with a sealing device, which is usually composed of a bearing body and a sealing device.

[0041] Bearing body: Like ordinary bearings, it consists of an inner ring, an outer ring, rolling elements such as balls and rollers, and a cage. The inner ring is usually mounted on the shaft, and the outer ring is mounted in the bearing housing. The rolling elements roll between the inner and outer rings, and the cage is used to separate the rolling elements, maintaining appropriate spacing and movement trajectory.

[0042] Sealing Device: This is the key part that distinguishes the 314 sealed bearing from ordinary bearings. Sealing devices are typically installed on both sides of the bearing and commonly include rubber seals and steel dust covers. These seals are fixed to the outer ring of the bearing by interference fit or other means and contact the inner ring or shaft surface, forming a relatively enclosed space. The function of the sealing device is to prevent dust, moisture, impurities, etc., from entering the bearing interior, while also preventing grease leakage, thereby ensuring the normal operation and service life of the bearing.

[0043] In this embodiment of the utility model, the sealing frame 316 and tempered glass allow observation of the interconnected area of ​​the first through hole on the hollow plate 32 and the second through hole on the hollow frame 31, facilitating fine-tuning of the internal interconnected range of the gas pipe 1 or liquid pipe 2. The sealing bearing 314 prevents the risk of gas or liquid leakage through the long rod 35. The protective sleeve 313 protects the first bevel gear 33 and the second bevel gear 34, ensuring their service life.

[0044] It should be noted that the air tube 1, liquid tube 2, magnetic ring 36, magnetic block 37 and sealed bearing 314 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
