Ear strap spot welding equipment of mask production machine

Abstract

The invention relates to ear strap spot welding equipment of a mask production machine, relates to the field of mask machining, and aims to solve the problem that ear straps are only welded to the outer surfaces of masks and are prone to falling off. The ear strap spot welding equipment comprises an operation table and a mounting plate arranged on the operation table. The operation table is provided with a mask trepanning mechanism and two groups of symmetrically arranged ear strap wire feeding mechanisms, a wire pushing mechanism and a welding mechanism; each ear belt feeding mechanism comprises a pay-off rod, a plurality of wire guide wheels, a wire pressing groove, a wire pulling clamp, a wire shearing knife and two wire clamping claws, an ear strap wire released on the pay-off rod is wound outside the wire guide wheels and penetrates through the wire pressing groove, the wire pulling clamp is movably connected along the side vertically arranged on the wire pressing groove, and the wire pulling clamp is used for pulling the ear strap wire to extend; and the wire shearing knife is arranged between one thread clamping claw close to the thread pressing groove and the thread pressing groove. The ear strap spot welding equipment has the effects that the mask can be punched, the ear strap lines penetrate through the mask, and therefore the ear strap lines are welded to the two faces of the mask, welding is more stable, and falling is not likely to happen.

Description

technical field [0001] The present application relates to the field of mask processing, in particular to an earband spot welding device for a mask production machine. Background technique [0002] When respiratory infectious diseases are prevalent or when working in dusty and other polluted environments, germs and dust in the air can enter the lungs of the human body through breathing and cause serious damage to the body. Wearing a mask can play a certain filtering role. The mouth 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 ear loops, there are usually single-point welding, double-point welding and semi-automatic welding. Single-point welding is to manually hold the mask and ear straps, and complete the welding of the four points where the ear straps are in contact with the mask; double-point welding is to c...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when the existing ear straps are welded, the two ends of the ear straps are usually welded to the outer surface of the mask. The part falls off, which affects the use of the mask
