[0023] like Figure 1As shown, this invention illustrates a precise mixing device for argon and carbon dioxide mixed gas in one embodiment. The device includes a workbench 1 with a mixing cabinet 6 at the top. Two argon tanks 5 and a carbon dioxide tank 8 are respectively located on either side of the mixing cabinet 6. The mixing cabinet 6 is connected to the argon tanks 5 and 8 via an output pipe 7. The workbench provides an installation platform for other components, ensuring the relative stability of each component's position. The mixing cabinet 6 is the core component of the device, typically containing multiple functional modules such as gas filtration, pressure reduction, pressure stabilization, flow control, and mixing. After the gas enters the mixing cabinet, it is filtered, pressure reduced, and stabilized at the gas inlet. A high-precision digital gas mass or volumetric flow meter controls and indicates the flow rate and pressure of various gases. Then, the PLC logic controls the start of the mixing process to achieve the desired mixing ratio. Rotating component 4, there are two sets of rotating components 4, which are respectively set at the bottom of argon tank 5 and carbon dioxide tank 8, to facilitate the rotation of the gas tanks for gas tank replacement. The fixing component 3 is provided in two sets. The two sets of fixing components 3 are respectively set on the upper end of the two sets of rotating components 4. The fixing component 3 is used to limit the argon tank 5 and carbon dioxide tank 8 to ensure the stability of the tanks during use, prevent shaking or tipping, and ensure the safety and stability of the gas transmission and mixing process. The lowering mechanism 2 consists of two sets, which are located on both sides of the workbench 1 to assist in the replacement of gas canisters. When the gas in the canister is used up, the lowering mechanism 2 can help remove the empty canister from the device, reducing the labor intensity of manual handling and improving the efficiency and safety of replacing gas canisters.

[0024] In some examples, such as Figure 2 As shown, the rotating assembly 4 includes a rotating plate 41. The top two sides of the worktable 1 are provided with mounting slots 13. A motor 42 is installed in the mounting slot 13. The output end of the motor 42 is fixedly connected to the bottom end of the rotating plate 41.

[0025] After the two sets of gas tanks are placed on the rotating plate 41 and fixed by the fixing component 3, when one set of gas tanks is used up and the other set of gas tanks needs to be replaced, the output pipe 7 is removed from the gas tank, the motor 42 drives the rotating plate 41 to slowly rotate the gas tank to 90 degrees, and the output pipe 7 is installed on the other set of gas tanks.

[0026] In some examples, such as Figure 2 and Figure 4 As shown, the bottom end of the rotating plate 41 is provided with an annular groove 12 on the top wall of the workbench 1, and an arc-shaped block 43 is symmetrically fixedly installed on the bottom wall of the rotating plate 41. The arc-shaped block 43 moves within the annular groove 12.

[0027] When the motor 42 drives the rotating plate 41 to rotate, the arc block 43 slides along the annular groove 12, restricting the displacement of the rotating plate 41.

[0028] In some examples, such as Figure 2 As shown, the bottom of both sides of the workbench 1 are provided with receiving grooves 10, and the front and rear side walls of the receiving grooves 10 are provided with moving grooves 11. The lowering mechanism 2 includes a support plate 21, which is slidably installed in the receiving grooves 10. Moving blocks 25 are fixedly installed on the front and rear sides of one end of the support plate 21. The moving blocks 25 are slidably connected in the moving grooves 11. An inclined plate 22 is provided at the top of the support plate 21, and several sets of rollers are provided on the surface of the inclined plate 22.

[0029] After the fixed component 3 releases the gas canister, the support plate 21 slides outward along the receiving groove 10. The operator gently pushes the gas canister, and the bottom of the gas canister rolls along the rollers on the inclined plate 22, smoothly moving from the rotating plate 41 to the inclined plate 22, and then sliding to the top of the support plate 21. The gas canister is then transferred to the ground outside the workbench 1 or to a transport vehicle. The new gas canister is pushed to the inclined plate 22, and the inclined plate 22 moves the gas canister closer to the rotating plate 41. The gas canister moves along the inclined plate 22 onto the rotating plate 41.

[0030] In some examples, such as Figure 2 As shown, the lower tank mechanism 2 also includes a support block 23, which is fixedly installed on both sides of the rotating plate 41. The two sides of the rotating plate 41 are provided with slots at the upper end of the support block 23. Rollers 24 are rotatably installed on the front and rear sides of one end of the inclined plate 22. The top of the support plate 21 is symmetrically provided with sliding grooves 9, and the two rollers 24 are slidably connected in the sliding grooves 9.

[0031] The movable block 25 slides along the movable groove 11, while the roller 24 at one end of the inclined plate 22 moves along the sliding groove 9, and the other end of the inclined plate 22 is embedded in the slot of the rotating plate 41. The support block 23 supports one end of the inclined plate 22.

[0032] In some examples, such as Figure 3 As shown, the fixing component 3 includes two mounting plates 31. The bottom ends of the two mounting plates 31 are fixedly installed on the top wall of the workbench 1 at the front and rear sides of the rotating plate 41. The surfaces of the two mounting plates 31 are provided with threaded grooves 14. The bottom ends of the two mounting plates 31 at the threaded grooves 14 are provided with through holes 15. Threaded rods 32 are threadedly connected in the two threaded grooves 14. Guide rods 34 are slidably connected in the two through holes 15. The threaded rods 32 move along the threaded grooves 14 of the mounting plates 31.

[0033] In some examples, such as Figure 3As shown, an arc-shaped plate 35 is provided at one end of the two threaded rods 32 that are close to each other. A fixing plate 37 is fixedly installed at the top of each of the two arc-shaped plates 35. Mounting holes 16 are opened on the outer surface of each of the two arc-shaped plates 35. Bearings 36 are fixedly installed in each of the two mounting holes 16. The inner ring surface of each of the two bearings 36 is fixedly connected to the outer surface of the two threaded rods 32 respectively.

[0034] When the knob 33 is turned, the threaded rod 32 moves along the threaded groove 14 of the mounting plate 31, causing the arc plate 35 to move closer to or further away from the gas tank. The clamping distance is adjustable. The inner wall of the arc plate 35 is provided with a rubber pad that is elastic to prevent the tank wall from being dented.

[0035] In some examples, such as Figure 3 As shown, a knob 33 is fixedly installed at the other end of each of the two threaded rods 32, and one end of each of the two guide rods 34 is fixedly connected to the outer surface of the arc plate 35. The other end of each of the two guide rods 34 passes through the through hole 15 and is fixedly installed with a fixing block 38.

[0036] After placing the gas cylinder on the rotating plate 41, rotate the front and rear knobs 33 respectively until the rubber pad of the arc plate 35 is in contact with the gas cylinder. The knobs 33 allow the operator to easily rotate the threaded rod 32. The guide rod restricts the movement direction of the arc plate to prevent the arc plate 35 from tilting when the threaded rod 32 is rotated. The fixing block 38 can prevent the guide rod from coming out of the through hole 15, thus improving operational safety.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
