The welding movable slider 232 is mounted on the welding movable seat 231; the welding movable slider 232 is movably mounted on the welding movable rail 233, so that the welding movable seat 231 moves along the welding movable rail 233; the output end of the moving driver 6 is provided with a moving driving column 61, and the moving driving column 61 is connected with the welding column 21; the welding movable seat 231 is sleeved on the movable driving column 61.

The welding moving assembly 23 is used for adjusting the moving state of the welding post 21 so that the welding post 21 keeps balance in the welding process, and the welding post 21 can stably weld the ear strap on the mask cloth, so that the welding stability is improved. Specifically, the welding moving rail 233 is mounted on the table 05, and the welding movable seat 231 is movably mounted on the welding moving rail 233 through the welding moving slider 232; since the welding movable seat 231 is sleeved on the movable driving column 61, when the output end of the movable driver 6 drives the welding column 21 to move, the movable driving column 61 is supported by the welding movable seat 231, and the welding movable seat 231 is movable, so that the gravity center of the movable driving column 61 is concentrated on the welding movable seat 231, the movement stability is improved, the movement of the movable driving column 61 is guided by the welding movable rail 233 to move, and the welding column 21 is not easy to deviate.

More preferably, the welding moving assembly 23 includes: a welding frame 24 and a welding guide post 25;

The welding guide post 25 is fixed to the welding frame 24; the movable welding seat 231 is movably connected to the welding guide post 25, and moves along the extending direction of the welding guide post 25 when moving.

When the movable driver 6 is an air cylinder, the movable driver 6 is mounted on the welding frame 24, and the output end of the movable driver is connected with the welding column 21, so as to drive the welding column 21 to move linearly, so that the welding column 21 passes through the welding extending port 130, and the ear belt is welded on the mask cloth at the welding extending port 130; the welding frame 24 is mounted on the workbench; in this embodiment, the welding guide post 25 is mounted on the welding frame 24 and is connected to the welding movable seat 231, and the welding guide post 25 can ensure that the welding movable seat 231 moves linearly, so that the welding post 21 is always linearly moved in a telescopic manner.

The technical principle of the present invention is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in any way as limiting the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
