Description

Technical Field

[0001] This utility model relates to the technical field of mask welding equipment, specifically a spot welding device for non-woven masks used for ear loop welding. Background Technology

[0002] The ear loops of a mask need to be welded onto the mask using a welding machine. The accuracy of the welding directly affects the strength of the ear loops, and masks with poor strength are classified as unqualified products.

[0003] However, most existing mask ear loop welding devices are single-point welders, requiring four welding operations per mask, which is cumbersome and inefficient. If double-point welding is used, the welding points are fixed and cannot be adjusted, thus limiting its applicability to different mask specifications. Utility Model Content
