Welding method and device for ear loops of non-woven tapered mask

Abstract

The invention provides a non-woven fabric conical mask ear belt welding method and operating manipulators, and relates to the technical field of mask welding. The operating manipulators for welding ofthe non-woven fabric conical mask ear belt comprises a conveying device, wherein long sliding grooves are formed in the outer surfaces of the front side and the rear side of the conveying device in the horizontal direction, four driving mechanisms are installed on the inner surface walls of the two sides of the long sliding grooves, sliding plates are fixed to one ends of the four driving mechanisms correspondingly, and the front sides of the sliding plates extend to the outer portions of the long sliding grooves. According to the non-woven fabric conical mask ear belt welding method and theoperating mechanical arm, in use, a mask can be conveyed between the two mechanical arms through the conveying device, after the conveying device is stopped, the position of the mask after conveying can be stopped, and meanwhile in use, through starting of a hydraulic cylinder, ultrasonic welding heads on the manipulators can be in contact with the mask for a long time, so that the mask and the ear belts can be better welded and fixed in use.

Description

technical field [0001] The invention relates to the technical field of mask welding, in particular to a welding method and device for non-woven tapered mask earbands. Background technique [0002] Welding is cladding or plating by brazing or welding. Welding is used in various fields. When processing masks, it is necessary to weld the masks and ear loops. Masks are a kind of sanitary products. Generally refers to the utensils worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper. It has a certain filtering effect. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. However, in the prior art, there are many ear wire welding methods in use. Since the conveying roller is continuously rotating, the welding time for the ultrasonic welding...

AI Technical Summary

Problems solved by technology

However, in the prior art, there are many ear wire welding methods in use. Since the conveying roller is continuously rotating, the welding time for the ultrasonic welding head to weld the ear wire to the mask sheet is relatively short, which will not only make the The part of the mask piece and the ear wire in the welding area cannot be completely melted, and the ultrasonic welding head cannot provide sufficient pressure for a long time, which will cause the ear wire to not be welded on the mask piece well. The ear wires are easy to fall off, which affects the quality of the mask. At the same time, after the existing masks are welded, the welded ear straps are transported through the conveying device. Since the conveying direction of the existing conveying device is fixed, in use, It is impossible to transport the welded masks in different directions. In use, it is not convenient to transport the welded masks
