Earband spot welding equipment for mask production machine

Abstract

The application relates to a spot welding device for ear straps of a mask production machine, and relates to the field of mask processing, so as to solve the problem that the ear straps are only welded to the outer surface of the mask and are prone to fall off. , the operating table is provided with a mask opening mechanism and two sets of symmetrically arranged ear belt wire feeding mechanisms, push wire mechanisms, and welding mechanisms; the ear belt wire feeding mechanism includes a wire pay-off rod, a number of wire wheels, and a wire pressure groove. , a wire clip, a wire cutter and two wire clamping claws, the ear strap wire released from the pay-off rod is wound on the outside of the wire wheel, and the ear strap wire passes through the wire pressing groove, and the wire wire clip is vertically arranged on the pressing wire. One side of the wire groove is movably connected, the wire clip is used to pull the ear strap wire to extend, and the wire cutter is arranged between a wire clamping claw near the wire pressing groove and the wire pressing groove. The present application has the effect that the mask can be punched so that the ear strap wire can pass through the mask, so that the ear strap wire can be welded with both sides of the mask, and the welding is more stable and less likely to fall off.

Description

technical field [0001] The application relates to the field of mask processing, in particular to a spot welding device for ear straps of a mask production machine. Background technique [0002] When respiratory infectious diseases are prevalent or when working in a polluted environment such as dust, germs and dust in the air can enter the human lungs through breathing, causing serious damage to the body. Wearing a mask can play a certain filtering role. The mask is tightly fitted, so that germs, dust, etc. cannot easily leak in. There are two ear straps on the mask, and the mask is fixed on the head by putting the ear straps on the ears. [0003] When making mask welding earbands, the commonly used methods are single-point welding, double-point welding and semi-automatic welding. Single-point welding is to manually hold the mask and the earband, and complete the welding of the four points where the earband and the mask are in contact; double-point welding is to complete the...
