Ear band welding device and mask manufacturing equipment

Abstract

The invention discloses an ear band welding device and mask manufacturing equipment. The ear band welding device comprises a first welding module, a second welding module and a cut-off assembly, wherein the first welding module comprises a first clamping assembly, a first driving assembly and a first welding assembly, the second welding module comprises a second clamping assembly and a second welding assembly. According to the ear band welding device, one ends of the two ear bands which are spaced from each other are clamped through the first clamping assembly, the two ear bands are pulled tomove to the positions above the adjacent short edges of the two adjacent continuous mask bodies, then the other ends of the two ear bands are clamped through the second clamping assembly, so that theear bands are fixed and conveyed in place, the ear bands are welded and fixed to the mask body through the welding assembly, a mask finished product can be obtained by subsequently cutting the mask body, two ear band welding devices do not need to be arranged on the downstream of a production line, the production line is simplified, the mask production efficiency is improved, and the mask weldingdevice is used for the technical field of mask production and manufacturing.

Description

technical field [0001] The invention relates to the technical field of mask production and manufacturing, in particular to an earband welding device and mask manufacturing equipment. Background technique [0002] The mask structure includes a mask body and two ear straps, each ear strap has two ends, and the two ends of the ear straps are fixed on the short sides of the mask body by welding. In related technologies, the mask machine is arranged in a "one-to-two" structure, that is, the mask body is formed by a mask body manufacturing device upstream, and then two mask ear strap welding devices are installed downstream to weld the ear straps on both sides of the mask. , A mask conveying line is also provided between the mask body manufacturing device and the two mask earband welding devices. This kind of "one drag two" mask machine has the following problems: [0003] 1. First form the mask body and then cut it, and weld the cut mask body to the ear straps, that is, the mol...

AI Technical Summary

Problems solved by technology

[0003] 1. First form the mask body and then cut it, and weld the cut mask body to the ear straps, that is, the molding of the mask body and the welding of the ear straps are two different processes, and the consistency of the mask manufactured by this process is poor , affecting the quality of the mask;

[0004] 2. It has a slender assembly line layout, which is complicated and inconvenient for assembly and long-distance transportation;

[0005] 3. The production process is complex and requires multiple cutting;

[0006] 4. When welding the ear loops, the welding head of the ear loops is unstable, resulting in weak welding or incomplete welding surfaces, which reduces the qualified rate of finished masks;

[0007] 5. The production line is lengthy, the mask production efficiency is not high, and it cannot meet the market demand
