Intermittent ear line welding equipment for mask production

Abstract

The invention discloses intermittent ear line welding equipment for mask production. The intermittent ear line welding equipment comprises a mask conveying device, an ear line conveying device, an earline clamping and conveying device and an ear line welding device. The ear line clamping and conveying device comprises two clamping modules, a vertical driving mechanism and a rotary driving mechanism. The two clamping modules are sequentially arranged in the conveying direction of mask bodies. Each clamping module comprises at least two clamping mechanisms and a clamping driving mechanism. Therotary driving mechanism is used for driving the two clamping modules to rotate in the opposite directions and driving the clamping mechanisms in each clamping module to rotate from an ear line clamping station to an ear line welding station. When the first clamping mechanism reaches the ear line welding station, the next clamping mechanism is located at the ear line clamping station. The ear lineconveying mechanism is used for conveying ear lines to the ear line clamping station. By the intermittent ear line welding equipment, ear line carrying time can be greatly shortened, and the production efficiency is improved in multiples.

Description

technical field [0001] The invention relates to mask production equipment, in particular to intermittent ear wire welding equipment for mask production. 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 l...

AI Technical Summary

Problems solved by technology

Among them, the wire clamping and conveying device is responsible for the transfer of the ear wire to be welded, which is the key action in the ear wire welding process. The existing wire clamping and conveying device usually adopts reciprocating movement, and the return journey of the wire clamping and conveying device is an empty stroke. , restricting the improvement of production efficiency
