[0002] The advantage of vacuum beam welding machine is that it reduces the presence of oxygen by applying a vacuum environment during the welding process, thereby preventing the welding material from reacting or oxidizing with oxygen in the air. Therefore, vacuum beam welding machine is becoming more and more widely used.

[0003] Publication number CN 210814507 U discloses a smoke removal device for a vacuum beam welding machine, wherein a vacuum pump is provided on one side of the operating table, a welding studio is provided on the other side of the operating table, a placement table is provided at the middle position inside the welding studio, a radiation port is provided above the placement table, a smoke removal chamber is provided at one end of the welding studio, a high temperature resistant box is provided on one side of the smoke removal chamber, and the high temperature resistant box is fixedly connected to the smoke removal chamber, a motor is provided on one side of the high temperature resistant box, and one end of the motor extends to the interior of the high temperature resistant box, and an air suction fan is provided at one end of the motor.

[0004] Welding in a completely vacuum environment will not produce smoke. The so-called vacuum beam welding machine in the prior art only tends to be vacuum, but there will always be air. Therefore, smoke will still be produced during the welding process. Because of the presence of air, the above patent can use a fan to guide the flow of smoke. The above patent uses spraying water to treat the smoke, but the spraying water falls quickly and the spraying distance is short, so that the contact between the spraying water and the smoke is less, resulting in unsatisfactory treatment effect of the spraying water on the smoke.

[0033] During implementation, the vacuum pump 29 is turned on through the operating table 28, so that the vacuum pump 29 draws out the air in the welding studio 1, allowing the welding studio 1 to be in a vacuum state, and then the vacuum pump 29 is turned off, and the object to be operated is placed on the placement table 31, and then the vacuum beam welder is turned on through the operating table 28 to perform vacuum welding on the object in the welding studio 1. Since there is still residual air in the welding studio 1, smoke will be generated. The first fan 5 and the second fan 6 are turned on through the operating table 28 to guide the smoke into the first smoke duct 3 and the cylindrical tube 14 for treatment.

[0034] Specifically, the smoke exhaust mechanism includes a smoke exhaust pipe 11 arranged in the water pipe 8, a plurality of support rods 12 are fixed to the top of the smoke exhaust pipe 11, a conical plate 13 is fixed to the top of the plurality of support rods 12, the sprinkler mechanism includes a water collecting tray 10 fixed to the bottom of the water pipe 8, the smoke exhaust pipe 11 passes through the water collecting tray 10 and is fixed to the water collecting tray 10, a plurality of sprinkler holes are provided on the bottom and side walls of the water collecting tray 10, the water pipe 8 and the cylindrical tube 14 are rotatably connected by a bearing 9, and a water collecting bin 16 is fixed to the top of the water pipe 8.

[0036] Embodiment 2

[0037] A smoke removal device for a vacuum beam welding machine, based on the first embodiment, has a plurality of second connecting rods 27 fixed at equal intervals on the outside of a spray head 7, and the second connecting rods 27 are fixed to the inner wall of a cylindrical tube 14 on the side away from the spray head 7, a recovery box 23 is fixed to and connected to the bottom of the first smoke guide tube 3, a water pump 24 is provided on one side of the recovery box 23, and a second water pipe 26 is fixed to and connected to the recovery box 23, one end of the second water pipe 26 is fixed to and connected to the water inlet of the water pump 24, a water outlet of the water pump 24 is fixed to and connected to a first water pipe 25, the first water pipe 25 passes through the cylindrical tube 14 and is fixed to the cylindrical tube 14, and the first water pipe 25 extends to the end inside the cylindrical tube 14 and is fixed to and connected to the water inlet on the spray head 7.

[0038] Specifically, a motor 21 is fixedly installed on one side of the first smoke guide tube 3, a second rotating shaft 20 is fixed to the output end of the motor 21, and the second rotating shaft 20 passes through the first smoke guide tube 3 and rotates inside the first smoke guide tube 3, a second conical wheel 22 is fixed to the end of the second rotating shaft 20 extending into the first smoke guide tube 3, a first rotating rod 17 is provided at the bottom of the smoke exhaust pipe 11, and a plurality of first connecting rods 18 are fixed to the outer side of the top of the first rotating rod 17, an end of the first connecting rod 18 away from the first rotating rod 17 is fixed to the inner wall of the smoke exhaust pipe 11, and a first conical wheel 19 meshing with the second conical wheel 22 is fixed to the bottom of the first rotating rod 17.

[0039] During implementation, the motor 21 is started to drive the second rotating shaft 20 to rotate. When the second rotating shaft 20 rotates, the first conical wheel 19 is driven to rotate through the second conical wheel 22, and then the first rotating rod 17, the water collecting tray 10, the water guide pipe 8, and the water collecting bin 16 are driven to rotate.
