Mask fixing band welding method

Abstract

The invention relates to a mask fixing band welding method. The mask fixing band welding method comprises the steps that S1, fixing band clamping jaws clamp a fixing band extending out of a guide linehole seat and move in the direction far away from the guide line hole seat, and the two groups of fixing band clamping jaws pull out a section of fixing band; S2, after the fixing band is pulled outto reach a preset length, two groups of thread clamping components clamp the two ends of one fixing band, a shearing mechanism cuts off the fixing band, two groups of thread clamping components are arranged at the two ends of a mask model component correspondingly, and the two fixing bands are clamped synchronously; and S3, the fixing band clamping jaws release the fixing band, and upper thread clamping plates and lower thread clamping plates of the thread clamping components drive the fixing band to be turned over to the two sides close to the mask model component and clamp the fixing band tobe tightly attached to a mask. According to the mask fixing band welding method, automatic operation is achieved, the labor intensity of workers is relieved, the labor cost is reduced, and the characteristic of high work efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of mask production equipment, in particular to a welding method for a mask fixing belt. 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, an...

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
