Description

Technical Field

[0001] The utility model relates to the technical field of mask processing, and particularly relates to a mask earband pressing device. Background Technique

[0002] A mask is a hygiene protection article, usually worn over the mouth and nose to filter the air entering the mouth and nose, and to block substances such as droplets, dust, and pollen in the air. Generally, a mask is hung on the human ear by earbands so that the mask body can fit snugly over the mouth and nose. Therefore, in the production process of masks, one of the steps is to bend the earbands into a semi-circular shape and then weld the two ends of the earbands to the mask body.

[0003] However, in the prior art, the manufacture of mask earbands is carried out by first manually cutting a small section, then manually bending the cut earbands into a semi-circular shape, and holding the two ends of the earbands to fix the earbands on the mask body, and finally using a welding device to weld the earbands. This method has a high labor cost, low production efficiency, high work intensity, and mechanical repetition. If not careful, quality problems such as wrong welding and missed welding may occur. Therefore, a mask earband pressing device is proposed. Summary of the Utility Model
