Mask manufacturing process and mask

Abstract

The invention discloses a mask manufacturing process and a mask. The mask manufacturing process comprises the following steps: preparing a mask main body sheet and elastic fabric; extending the mask main body sheet in a transverse direction to form a plurality of continuous mask main body units; extending the elastic fabric in the transverse direction to form a plurality of continuous material belt units, and equipping each material belt unit with a left side hanging lug part and a right side hanging lug part; stacking the elastic fabric and the mask main body sheet up and down and conveying and compounding the elastic fabric and the mask main body sheet transversely, and arranging the material belt units and the mask main body unit correspondingly; then, welding and connecting the two ends of the material belt units with the two ends of the mask main body unit to form a plurality of mask single bodies. Therefore, the traditional ear belt welding mode is replaced by overlapping and welding the elastic fabric with the continuous material belt units; the manufacturing process is simple and ingenious; the mask production efficiency is greatly improved;mask production can be completedonly by depending on one mask production device; stable operation of the device is facilitated; and the batch production capacity is improved.

Description

technical field [0001] The invention relates to the technology in the field of masks, in particular to a mask manufacturing process and a mask. Background technique [0002] Flat masks have the advantages of simple structure, low production cost, convenient and light to wear, and are widely used in dust prevention, filtration, disinfection, etc. A flat mask is mainly composed of a mask body and ear straps. The mask body is generally divided into three layers: inner, middle, and outer. The inner layer is made of skin-friendly material, the middle layer is an isolation filter layer, and the outer layer is made of waterproof non-woven fabric or special antibacterial material. Layers, etc., the main body of the mask is mostly set in a rectangle, and a nose bridge strip is arranged in the center of the upper end of the main body of the mask to fix the main body of the mask on the bridge of the nose, making the wearing of the mask more firm and comfortable.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a combination of multiple devices is usually used to produce a flat mask. For example, the mask body is made by a mask body manufacturing machine, and then the elastic ear straps are welded by an ear strap welding machine; A lot of equipment is required, the total cost of the equipment is high, and the equipment takes up a lot of space in the workshop, which is not convenient for production management; especially, after the main body of the mask is made, it needs to be cut into individual mask main bodies, and then the main body of the mask is transferred to the ear. With a welding machine, the process of transferring the main body of the mask to the ear loop welding machine takes a lot of time, and welding the ear loops on the ear loop welding machine is also troublesome, resulting in a longer time required for welding the ear loops after the mask main body is completed In this way, the overall production efficiency of the flat mask is bound to be limited, and it cannot meet the actual production needs of the enterprise.
