[0030] The flow rate regulating mechanism 2 is arranged inside the conveying mechanism 1 and is used to regulate the flow rate of argon gas.

[0031] In order to conveniently adjust the flow rate of argon gas, Figure 2-3 and Figure 5 As shown, the flow regulating mechanism 2 includes a fixed plate 201, which is arranged at one end of the interior of the conveying mechanism 1. A mounting rod 203 is rotatably mounted on the inner wall of the fixed plate 201. A driven gear 204 is fixedly sleeved on the outer side of the end of the mounting rod 203 away from the fixed plate 201. A movable plate 205 is fixedly sleeved on the outer side of the end of the mounting rod 203 close to the fixed plate 201. Three through holes 206 are provided on the inner walls of the fixed plate 201 and the movable plate 205. A sealing gasket 210 is provided on the end of the fixed plate 201 away from the movable plate 205. The flow regulating mechanism 2 also includes a rotating shaft 207. The driving shaft 207 is arranged on the top inner wall of the conveying mechanism 1, and a servo motor 208 is arranged on the top of the rotating shaft 207. A driving gear 209 is fixedly sleeved on the outer side of the bottom of the rotating shaft 207. The driving gear 209 is meshed with the driven gear 204. The servo motor 208 works to rotate the rotating shaft 207. Through the meshing action between the driving gear 209 and the driven gear 204, the through hole 206 on the inner wall of the movable plate 205 can be aligned with the through hole 206 on the inner wall of the fixed plate 201, so that the argon gas inside the argon tank can be conveniently transported to the subsequent work section through the conveying mechanism 1.

[0032] In order to ensure that the delivery mechanism 1 can be stably connected to the outlet flange of the argon tank, Figure 2 and Figure 4 As shown, the conveying mechanism 1 includes a gas pipe 101, and a placement groove 102 is opened on the inner wall of one end of the gas pipe 101 close to the outlet flange of the argon gas tank. A sealing ring 103 is movably installed on the inner wall of the placement groove 102. A connecting bolt 104 is arranged between the inner wall of one end of the gas pipe 101 and the outlet flange of the argon gas tank and is fixedly connected by the connecting bolt 104. The sealing ring 103 can seal the connection position between the gas pipe 101 and the outlet flange of the argon gas tank to avoid leakage of argon gas at the connection position.

[0033] In order to ensure that the fixing plate 201 can be kept stable inside the gas pipe 101, Figure 2 As shown, an internal thread is provided on the inner wall of one end of the gas pipe 101 away from the outlet flange of the argon gas tank, and mounting grooves 105 are provided on the top and bottom of the inner wall of the end of the gas pipe 101 away from the outlet flange of the argon gas tank. A movable seat 202 is fixedly installed on the top and bottom of the fixed plate 201, and the outer wall of the movable seat 202 is movably connected to the inner wall of the adjacent mounting groove 105. The top and bottom outer walls of the sealing gasket 210 are movably connected to the inner walls of the two mounting grooves 105 respectively, and support rods 211 are fixedly installed on the top and bottom of the outer wall of one end of the sealing gasket 210. The two support rods 211 are respectively in contact with the outer walls of the two movable seats 202. The sealing gasket 210 can seal the connection position between the gas pipe 101 and the subsequent pipeline, and the movable seat 202 can be pressed by the support rod 211, so that the fixed plate 201 can remain stable inside the gas pipe 101.

[0034] In order to make the flow regulating mechanism 2 able to stably regulate the flow of argon gas, Figure 2 and Figure 5 As shown, the inner diameter of the gas pipe 101 is the same as the outer diameter of the fixed plate 201, the outer diameter of the fixed plate 201 is the same as the outer diameter of the movable plate 205, the three through holes 206 on the inner wall of the fixed plate 201 and the three through holes 206 on the inner wall of the movable plate 205 are arranged alternately, and the through holes 206 are arranged in a fan-shaped structure. By adjusting the gap between the through holes 206 on the inner wall of the fixed plate 201 and the through holes 206 on the inner wall of the movable plate 205, the flow rate of argon gas can be adjusted.

[0035] In order to provide power for the rotation of the movable plate 205, as Figure 2 As shown, the inner wall at the top of one end of the air supply pipe 101 close to the movable plate 205 is rotatably connected to the rotating shaft 207, and the top of the outer wall at one end of the air supply pipe 101 close to the movable plate 205 is fixedly connected to the servo motor 208. The servo motor 208 and the rotating shaft 207 are connected by an output shaft transmission. The air supply pipe 101 can install and fix the rotating shaft 207 and the servo motor 208. The operation of the servo motor 208 causes the rotating shaft 207 to rotate, and through the meshing action between the driving gear 209 and the driven gear 204, the movable plate 205 can be rotated.

[0036] The specific implementation method is as follows: when the argon gas is transported to the required section, the gas delivery pipe 101 is connected to the outlet flange of the argon tank, so that the sealing ring 103 can be placed in the placement groove 102, so that the sealing ring 103 can connect and seal the connection position between the outlet flange and the gas delivery pipe 101, and then the connecting bolt 104 penetrates the inner wall of one end of the gas delivery pipe 101 and connects to the outlet flange of the argon tank, so that the delivery mechanism 1 can be stably connected to the argon tank, and the movable plate 205 and the fixed plate 201 are placed at one end of the gas delivery pipe 101, so that the movable seat 202 can be moved along the two The inner wall of the mounting groove 105 moves inward, so that the driven gear 204 can mesh with the driving gear 209, and then the sealing gasket 210 is installed on the inner wall of the end of the gas pipe 101 away from the argon tank, so that the two support rods 211 can press the fixing plate 201, so that the fixing plate 201 can remain stable inside the gas pipe 101, and at the same time, the inner thread of the inner wall of one end of the gas pipe 101 is connected with the outer thread of the outer wall of the subsequent pipeline, and the sealing gasket 210 can be pressed by the subsequent pipeline, so that the sealing gasket 210 can seal the connection position between the gas pipe 101 and the subsequent pipeline;

[0037] After the conveying mechanism 1 and the flow regulating mechanism 2 are installed, the servo motor 208 is operated to rotate the rotating shaft 207, and then the driving gear 209 is rotated. Through the meshing action between the gear parts, the driven gear 204 is rotated, and then the mounting rod 203 is rotated, which can drive the movable plate 205 to rotate. The correspondence between the three through holes 206 on the inner wall of the movable plate 205 and the three through holes 206 on the inner wall of the fixed plate 201 can be adjusted, and then the flow rate of argon gas can be adjusted. The intake amount of argon gas can be conveniently adjusted according to demand. This embodiment specifically solves the problem that the device cannot be conveniently installed and disassembled, and the intake amount of argon gas cannot be conveniently adjusted in the prior art.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
