the welding movable slider 232 is mounted on the welding movable seat 231; the welding moving slider 232 is movably mounted on the welding moving rail 233, so that the welding moving seat 231 moves along the welding moving rail 233; the output end of the mobile driver 6 is provided with a mobile driving column 61, and the mobile 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 column 21, so that the welding column 21 keeps balance in the welding process, and the welding column 21 can weld the ear strap to the mask cloth stably, and the welding stability is improved. Specifically, the welding moving rail 233 is mounted on the work table 05, and the welding moving seat 231 is movably mounted on the welding moving rail 233 by the welding moving slider 232; and because 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 can move, so that the center of gravity of the movable driving column 61 is centralized on the welding movable seat 231, the moving stability is improved, the movement of the movable driving column 61 is guided by the welding moving track 233, and the welding column 21 is not easy to shift.

More preferably, the welding movement assembly 23 comprises: a welding frame 24 and a welding guide 25;

the welding guide column 25 is fixed to the welding frame 24; the welding movable 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 moving driver 6 is an air cylinder, the moving driver 6 is installed on the welding frame 24, and the output end of the moving driver is connected with the welding column 21 and used for driving the welding column 21 to move linearly, so that the welding column 21 passes through the welding extending port 130, and the ear band is welded on the mask cloth at the welding extending port 130; the welding frame 24 is arranged on the workbench; in the embodiment, the welding guide post 25 is installed on the welding frame 24 and 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 guide post 21 always moves linearly when extending and retracting.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
