[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer toFigures 1-3 , the present utility model provides a technical solution: a mask pressing device, including a pressing device main body 1, on which there is a box body 5. Inside the box body 5, there are a feeding chamber 9, a pressing chamber 6 and a cooling chamber 2. And there are partition boards 4 respectively between the feeding chamber 9, the pressing chamber 6 and the cooling chamber 2. The air outlets 18 face both sides respectively, and the air outlets 18 are close to one side of the mask. This structure can blow and smooth the non-woven fabric by making the air outlets 18 blow towards both sides, so as to prevent wrinkles from generating between the non-woven fabrics. Above the feeding chamber 9, there is a material roll rack 7 installed, and inside the feeding chamber 9, there are also connecting seats 10 corresponding to the material roll rack 7. The connecting seats 10 are inclined at different angles respectively, and the connecting seats 10 are respectively located above the sides of the pre-pressing pinch rollers 16. This structure can respectively guide the non-woven fabrics conveyed from different directions by the first guiding roller 8 and the second guiding roller 17 installed on the connecting seats 10 by making the connecting seats 10 inclined at different angles, ensuring that the non-woven fabrics are conveyed to the pre-pressing pinch rollers 16. Inside the connecting seats 10, the first guiding roller 8 and the second guiding roller 17 are respectively rotatably installed, and there are also air outlets 18 on the connecting seats 10. The first guiding roller 8 and the second guiding roller 17 have the same structure, and the air outlets 18 are arranged between the first guiding roller 8 and the second guiding roller 17. This structure can blow the non-woven fabric conveyed between the first guiding roller 8 and the second guiding roller 17 by the air outlets 18, and by arranging the air outlets 18 between the first guiding roller 8 and the second guiding roller 17, it is avoided that the air outlets 18 affect the guiding and conveying of the non-woven fabric by the first guiding roller 8 and the second guiding roller 17. Inside the pressing chamber 6, there are successively a wrinkle forming mechanism 15, an alignment pinch roller 14, a preheating box 13 and a pressing pinch roller 12. The air outlet 18 and the preheating box 13 are connected through a pipe fitting. This structure can allow heat flow to be introduced into both the air outlet 18 and the preheating box 13, and by preheating the fed non-woven fabric, it is ensured that each layer of non-woven fabric is relatively closely laminated. And the preheating box 13 performs heat flow heating treatment on the wrinkled mask, making the mask easy to press after preheating. Inside the cooling chamber 2, there is a cooling mechanism 3 and a discharging guiding pinch roller 11 installed. Inside the feeding chamber 9, there is also a pre-pressing pinch roller 16 rotatably installed, and the non-woven fabric between the pre-pressing pinch roller 16, the pressing pinch roller 12 and the preheating box 13 is horizontally conveyed. This structure can respectively convey the non-woven fabrics guided by the first guiding roller 8 and the second guiding roller 17 between the pre-pressing pinch rollers 16, and the pre-pressing pinch rollers 16 perform lamination treatment on the non-woven fabric.

[0018] Working principle: When using this mask pressing device, first, the coil material used for mask production is installed on the coil rack 7. After each layer of coil material enters the feeding chamber 9, it is respectively guided between the first guiding roller 8 and the second guiding roller 17 and introduced between the pre-pressing pinch rollers 16 to achieve multi-layer superposition of the mask. The air outlet 18 arranged on the connecting seat 10 between the first guiding roller 8 and the second guiding roller 17 blows air on the non-woven fabric. The air outlet 18 blows air to both sides to smooth the non-woven fabric. At the same time, the hot air blown out preheats the non-woven fabric to ensure that each layer of non-woven fabric is tightly attached to each other after being pre-pressed and clamped by the pre-pressing pinch rollers 16. Then, the non-woven fabric is transported into the pressing chamber 6, and the folding forming mechanism 15 performs the folding forming process of the mask, and through the existing structure for fixing the nose bridge strip, the nose bridge strip is buried into the mask. Then, the alignment pinch rollers 14 press the formed folds and ensure that the folded mask enters the preheating box 13 for preheating treatment. Then, the pressing pinch rollers 12 clamp the mask to achieve the pressing process of the mask. After that, the mask is transported into the cooling chamber 2. After the cooling mechanism 3 cools and forms the mask, the discharging guiding pinch rollers 11 move the mask out of the box body 5 for subsequent processing such as cutting. The partition plate 4 is used for separating the feeding chamber 9, the pressing chamber 6, and the cooling chamber 2, thus completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
