In actual work, the rolled ear belt is placed on the ear belt hanging rod 22, and the winding mode of the ear belt is as follows: the ear belt is firstly wound downwards on the conveying wheel 25, the pressing wheel 26 presses the ear belt on the conveying wheel 25, then the ear belt is wound downwards on the lifting wheel 27, then the ear belt is wound upwards on the guide wheel 212, and then the ear belt passes through the winding mechanism 3. The ear belt conveying motor 24 drives the conveying wheel 25 to rotate, and the rotary conveying wheel 25 conveys the ear belt to the winding mechanism 3. In the rotating process of the conveying wheel 25, the position sensor detects the position of the lifting wheel 27 in real time, when the position sensor detects that the lifting wheel 27 reaches the lower guide pillar mounting block 210, it shows that the conveying speed of the ear belt is too high, the position sensor feeds back a signal to the control cabinet, and the control cabinet controls the ear belt conveying motor 24 to slow down the rotating speed, so that the tension of the ear belt in the conveying process is ensured. When the position sensor detects that the lifting wheel 27 reaches the adjusting limit block 211, it indicates that the conveying speed of the ear belt is too low, the position sensor feeds back a signal to the control cabinet, and the control cabinet controls the ear belt conveying motor 24 to accelerate the rotating speed, so that the tension of the ear belt in the conveying process is ensured.

Meanwhile, the ear belt conveying mechanism 2 can ensure the tension of the ear belt by controlling the rotating speed of the ear belt conveying motor 24, thereby ensuring that the ear belt can be accurately welded on the mask body. Specifically, because the ear straps have certain elasticity, if the tension of the ear straps is too large in the conveying process, the ear straps welded on the mask body are too few, and the ears can be tightened by the ear straps. On the contrary, if the tension of the ear belt is too small in the conveying process, the ear belt welded on the mask body is too much, the mask body cannot be tightly attached to the face, and the protection effect is reduced.
