Mask fixing band welding device

Abstract

The invention relates to a mask fixing band welding device. The device comprises a mask conveying mechanism, a welding mechanism, a clamping mechanism located below the welding mechanism, a feeding mechanism, a shearing mechanism arranged close to the feeding mechanism and a bending butt joint mechanism, wherein the welding mechanism comprises a left welding assembly and a right welding assembly which are oppositely arranged; the bending butt joint mechanism comprises two sets of bending butt joint assemblies which are oppositely arranged; the two sets of bending butt joint assemblies, the left welding assembly and the right welding assembly are arranged in a square mode; and the bending butt joint mechanism comprises a pair of fixed supporting blocks, line clamping assemblies arranged atthe front ends of the fixed supporting blocks, translation air cylinders connected with the rear ends of the fixed supporting blocks and overturning assemblies connected with the line clamping assemblies. According to the invention, the overturning assemblies drive the line clamping assemblies to turn over in the direction close to a mask, the line clamping assemblies enable clamped fixing bands to be tightly attached to the two sides of the mask, and the left welding assembly and the right welding assembly weld the fixing bands to the two sides of the mask, so that full-automatic production is achieved, the production efficiency is greatly improved, and the welding positions of the fixing bands are accurate.

Description

technical field [0001] The invention relates to the technical field of mask production equipment, in particular to a mask fixing belt welding device. 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 human lungs through breathing and cause serious damage to the body. Wearing a mask can play a certain role in filtering. The mask should fit closely with the face so that germs and dust cannot easily leak in. The mask is equipped with a fixing belt. Most of the existing masks use the fixing belt to fix the mask on the ear. The fixing belt is easy to fall from the ear, affecting wearing performance. [0003] At present, there are head-mounted masks on the market, and two fixing straps are hung on the head, which is firm to wear. The manufacture of the head-mounted mask is to fold the mask body, cut out a small section of fixing belt manually, and weld...

AI Technical Summary

Problems solved by technology

This method has high labor costs, low production efficiency, high work intensity, mechanical repetition, and quality problems such as wrong welding and missing welding may occur if you are not careful.

Therefore, it cannot meet the actual production needs of enterprises, especially in the case of tight supply of existing masks, the efficiency of this production method cannot be applied to the urgent needs of the current market
