Mask ear band high-speed pressure welding method

Abstract

The invention relates to the field of mask manufacturing, in particular to a mask ear band high-speed pressure welding method. The mask ear belt high-speed pressure welding method comprises the following steps: a plurality of wire pulling units are moved circularly; when the wire pulling units are located at different stations, wire winding, clamping, cutting off and pressure welding are completedrespectively, in the wire winding process, ear ropes are wound around the wire pulling units and bent into the shape meeting the standard mask ear belts, in the clamping process, the bent ear ropes are fixed, in the cutting-off process, the continuous ear ropes are cut off into ear belts, and in the pressure welding process, the ear belts are connected to a mask. After the scheme is adopted, through creative design, the pressure welding efficiency of the mask ear bands is greatly improved.

Description

technical field [0001] The invention relates to the field of mask production, in particular to a high-speed pressure welding method for ear loops of a mask. Background technique [0002] When a large-scale epidemic breaks out, in order to prevent cross-infection, both healthy and infected people should wear masks. However, due to the large population in China, the daily consumption of masks is huge, so the production efficiency of masks is very important. [0003] In the production of masks, two ear straps need to be pressure-welded on both sides of the mask. In the production of existing masks, the ear strap welding device is installed on the side of the mask conveyor belt. The pressure welding of the ear straps generally includes the following steps: The ear rope of the earband is pulled to the side of the conveyor belt, and is clamped left and right by two air claws, and then the ear rope is cut off by the cutter mechanism to form an earband that meets the standard size, ...

AI Technical Summary

Problems solved by technology

[0004] That is, after a mask is conveyed in place, the connection of the ear straps on one side needs at least four actions: clamping, cutting, bending, and pressure welding. °Carry out pressure welding on both sides, and if a fully automatic pressure welding device is used, the production efficiency is improved compared to semi-automatic, but the pressure welding devices on both sides need a higher synchronization rate, so it will produce a higher failure rate. After A period of production time requires professionals to debug the system, and even if fully automatic production is adopted, when the air grippers under the control of the controller are in motion, the response time required for each step will still not change, and the production of masks is still subject to ear straps welding efficiency
