Novel full-automatic welding machine for mask ear ropes

Abstract

The invention discloses a novel full-automatic welding machine for mask ear ropes. The novel full-automatic welding machine comprises a mask conveying device, two ear rope conveying devices and two ultrasonic welding devices; the two ear rope conveying devices are arranged above the mask conveying device in parallel at intervals, and each ultrasonic welding device corresponds to one ear rope conveying device and is arranged below the ear rope conveying device; the mask conveying device comprises a chain plate conveying line mechanism, a plurality of supporting plate mechanisms and an overturning mechanism; the plurality of supporting plate mechanisms are arranged on the chain plate conveying line mechanism at intervals and used for being sleeved with masks, and the overturning mechanism isfixedly installed on the chain plate conveying line mechanism and located between the two ear rope conveying devices; two flanging mechanisms are further fixedly installed on the chain plate conveying line mechanism, and each flanging mechanism is arranged close to one side of one ear rope conveying device. The novel full-automatic welding machine can achieve the procedures of automatic conveying, bending, shearing, welding, discharging and the like of ear ropes, and is high in automation degree, high in production efficiency, reasonable in overall design, compact in structure, small in size,low in cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of mask ear strap welding, in particular to a new type of fully automatic welding machine for mask ear straps. Background technique [0002] A mask is a kind of sanitary protection product, which is usually worn on the nose and mouth to filter the air entering the nose and mouth, thereby blocking the droplets, dust, pollen and other substances in the air. Masks are generally buckled on the ears of the human body by ear straps so that the mask fits the mouth and nose. Therefore, in the production process of the mask, the most important step is to bend the ear straps into an arc (semicircle shape), and then weld the two ends of the ear straps on the surface of the mask. [0003] However, the existing method of welding the ear straps basically adopts a manual method, that is, manually cut out a small section, then bend it into a semicircle, and finally use a welder to weld it on the mask. This production metho...

Problems solved by technology

[0003] However, the existing method of welding the ear straps basically adopts a manual method, that is, manually cut out a small section, then bend it into a semicircle, and finally use a welder to weld it on the mask. This production method is costly and expensive. The work intensity is high, and the production efficiency is low. At the same time, because it is a mechanical repetitive work, after the physical strength of the workers decreases, it is easy to make mistakes, resulting in the production quality cannot be guaranteed.
