Ear wire welding device for planar mask machine

Abstract

The invention discloses an ear wire welding device for a planar mask machine, comprising a frame, an ear wire loading apparatus and an ear wire welding apparatus. The ear wire loading apparatus comprises an ear wire conveying apparatus, an ear wire clamping and carrying apparatus and an ear wire shearing apparatus; the ear wire conveying apparatus comprises a clamping base, a first clamping mechanism and a clamping conveying mechanism; the ear wire clamping and conveying apparatus comprises a bracket, a second clamping mechanism, a vertical driving mechanism and a rotary driving mechanism; therotary driving mechanism is used for driving the second clamping mechanism in the same set to reversely rotate at the same time; the ear wire shearing apparatus is used for shearing an ear wire afterthe second clamping mechanism clamps the ear wire; and the ear wire welding apparatus comprises an ultrasonic welding head, a movable mold and a movable mold driving mechanism. The ear wire welding device of the invention is suitable for welding the ear wire of a mask body conveyed on a guide rail in the length direction of a mask; and the welded ear wire is positioned within the edge of a mask basal body to facilitate subsequent packaging.

Description

technical field [0001] The invention relates to a flat mask machine, in particular to an ear wire welding device for the flat mask machine. Background technique [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. The mask is mainly made of non-woven fabrics Made of gauze, the mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0003] Existing masks are generally produced automatically by mask production equipment. The mask production equipment manufactures a filter with a certain filtration performance through processes such as hot pressing, folding, ultrasonic welding, waste removal, and welding of ear loops and nose...

AI Technical Summary

Problems solved by technology

The mask welding system in the above-mentioned one-to-two automatic flat mask machine can only perform ear wire welding on the mask body conveyed along the width direction of the mask on the guide rail, but cannot weld the mask body conveyed along the length direction of the mask on the guide rail. achieve welding
