Description

Technical Field

[0001] The invention relates to the field of mask production equipment, and in particular to a welding machine which is convenient for welding the ear wires of masks. Background Art

[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, viruses, and droplets from entering and exiting the wearer's mouth and nose. Masks are mainly made of non-woven fabrics and gauze. Masks have a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in an environment polluted by dust.

[0003] In the mask production process, the welding process of the mask body and the ear wire is the main link that restricts the mask production speed. Specifically, in the existing mask production equipment, the mask body is sequentially transported to the ear strap welding station by the mask conveying device, and the ear wire is transported and cut by the ear wire conveying device. Then, the cut ear wire is transferred to the ear wire welding station by the wire clamping conveying device, and finally, the ear wire is welded to the mask body by the ear wire welding device. Among them, the wire clamping conveying device is responsible for the transfer of the ear wire to be welded, which is the key action in the ear wire welding process. The existing wire clamping conveying device usually adopts a reciprocating transport action, and the return stroke of the wire clamping conveying device is an empty stroke, which restricts the improvement of production efficiency.

When the welding head descends, the welding head heat presses the mask piece and the two ends of the inverted V-shaped ear wire unit on the base platform to heat seal the ear wire on the mask piece. During the operation, each inverted V-shaped ear wire unit corresponds to one side ear wire end of the mask, and has a certain stretching effect on the ear wire during the transmission process of the ear wire.

[0033] S3: Hot-press welding of ear wires: The user controls the earmuff to be welded to enter from the extension platform 20. At this time, the infrared sensing end 23 senses the signal of the earmuff to be welded and transmits the signal to the control center 2.
