Embodiment 1

[0034] This application provides a method for processing flat masks, see figure 1 , Figure 4 , Figure 5 as well as Image 6 shown, including steps:

[0035] S1. Composite the mask raw materials to make the main body of the mask; what needs to be said is, if Figure 4 As shown, the mask main body 2 production steps can be the same as the traditional mask main body 2 production steps, that is, the existing mask main body production equipment can be used for outer layer non-woven fabric 11, middle layer melt blown cloth 12, inner layer non-woven fabric 13 And mask raw materials such as bridge of the nose strip 14 are compounded to generate the required mask main body 2, those skilled in the art can make appropriate transformations on this basis, and specifically do not limit.

[0036] S2. Fold the elastic strip material used to prepare the elastic ear strap and have elastic deformation at least less than its own width direction along its own width direction; it should be no...

Embodiment 2

[0043] In addition to the method steps provided in the first embodiment above, the present application also includes the following method steps:

[0044] S21. Point pressing the folded position of the elastic strip. It should be noted that: due to the recovery deformation of the folded elastic strip, this easily affects the accuracy of the chopping process of the elastic strip 4 and also easily affects the subsequent transfer and compounding. For this reason, the present application adds a point pressing step between step S2 and step S3 to carry out point pressure on the folded position of the elastic strip 4 to ensure that the elastic strip 4 will not recover from deformation, and it is also convenient for subsequent use. Easy to pull and unfold. Such as Figure 7 as well as Figure 8 As shown, the folding position of the elastic strip can be point-pressed by point-pressing equipment such as the point-pressing roller 6, so that the overlapping positions of the elastic stri...

Abstract

The invention discloses a planar mask processing method. The processing method comprises the following steps: compounding mask raw materials into a mask body; folding an elastic band material which isused for preparing elastic ear hanging bands and has elastic deformation at least in the width direction of the elastic band material in the width direction of the elastic band material; chopping thefolded elastic strip along the length direction of the elastic strip according to a preset chopping width to prepare ear band main bodies; sequentially compounding the ear band bodies on the mask body in the length direction of the mask body, wherein the center lines of the ear band bodies in the length direction of the ear band bodies coincide with slitting lines of the mask body; and sequentially slitting the mask body along the slitting line of the mask body. The elastic band material is folded and chopped to form the ear band bodies, the ear band bodies are directly compounded on the mask body, and then slitting is carried out to directly process the mask with the ear bands, so that the transfer and secondary conveying processes are reduced, the production synchronization of the maskand the elastic ear hanging band is realized, the production efficiency is greatly improved, and the high-speed production of a planar mask is realized.

Description

technical field [0001] The technical field of mask processing of the present application relates in particular to a method for processing a flat mask. Background technique [0002] Planar mask is a kind of mask, which adopts a design similar to a planar structure. The existing planar mask structure includes a mask body and two ear-hanging ropes fixed on the mask body; the processing process is as follows: first process the mask body, then divide the mask body into individual mask bodies, and then pass through mechanisms such as cylinders to Flip over to a conveyor belt perpendicular to the main body forming machine. The conveyor belt conveys the product forward through intermittent motion. After the product is sent to the welding station of the hanging ear rope, the hanging ear rope is welded on the main body. However, such a processing process requires transfer and secondary transportation, which is inefficient and slow, and it is difficult to achieve high-speed production...
