A rotating table is rotatably arranged on the upper part of the workbench for rotating the mask. A pull wire assembly is fixedly arranged on the workbench for quantitatively pulling the ear band and cutting the ear band. A wire taking assembly is arranged on the upper part of the top plate, and the wire taking assembly is used to collect the cut ear band. An ear band coil is rotatably arranged on the connecting shaft. The ear band can be guided by the ear band sliding groove on the support plate to prevent the ear band from winding during pulling. The first rotating cylinder rotates to drive the screw rod to further push the sliding seat to slide. The first clamping cylinder clamps one end of the ear band to pull the ear band while the sliding seat slides. The number of rotations of the screw rod determines the length of the pulled ear band. Then, the ear band is cut by the cutting cylinder. However, the device needs to be placed on the rotating table by manual operation to perform welding.
