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. like 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 strip a...

Abstract

The application discloses a method for processing a flat mask, comprising the steps of: compounding mask raw materials into a mask main body; folding an elastic strip that is used to prepare elastic ear straps and has elastic deformation at least in its own width direction along its own width direction ; The folded elastic strip is chopped along its own length according to the preset chopping width to make the main body of the ear straps; the main body of the ear straps is sequentially compounded on the main body of the mask along the length direction of the main body of the mask, wherein the main body of the ear straps The center line in the direction of its own length coincides with the tangent line of the main body of the mask; the main body of the mask is slit sequentially along the tangent line of the main body of the mask. Folding and chopping the elastic strip to form the main body of the ear straps, and then directly compounding the ear straps to the main body of the mask, and then cutting to directly process the mask with the ear straps, reducing the transfer and secondary conveying process, and realizing the mask Synchronized with the production of elastic ear straps, it greatly improves production efficiency and realizes high-speed production of flat masks.

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...
