[0001] The present invention belongs to the field of mask manufacturing, and particularly relates to a folding device, a folding method and a product of a foldable flat mask. Background Art

[0002] Existing medical surgical masks or general medical masks are all flat masks. Such masks are composed of a surface layer, an intermediate layer, a bottom layer, mask straps and a nose clip strip. The layer in contact with the human face is the bottom layer. Since the existing flat masks, whether single-packaged or multi-packaged, are packaged in a flat-laying manner, there are defects that the packaging materials used have a large volume, and when the user takes them out, it is easy to contact the bottom layer, which is likely to cause contamination to the bottom layer. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the folding device, folding method and product of the foldable flat mask provided by the present invention can fold a traditional flat mask into a foldable flat mask, thereby protecting the bottom layer of the mask from being contaminated. When the user takes the mask, the user's hand will not contact the bottom layer of the mask, so the bottom layer of the mask will not be contaminated; when the user takes out and wears the mask, the user only needs to contact the surface layer of the mask body and will not contact the bottom layer of the mask.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions to achieve:

Specific embodiments

[0038] The preferred solution is as Figures 1 to 7 shown. A folding device for a foldable flat mask includes a frame 1. A feeding conveying device 2 is provided on the frame 1. The output end of the feeding conveying device 2 is provided with a supporting table 3. A mask folding opening 4 is provided on the supporting table 3. Above the mask folding opening 4 is provided a mask folding plate 5, and the mask folding plate 5 is driven by a folding driving device 7; below the mask folding opening 4 is provided a shaping conveying device 6 or a shaping channel.

[0039] The feeding conveying device 2 can be a belt conveyor, which is used to transport the flat masks 9 individually and at equal intervals to the supporting table 3. The flat masks 9 stay directly above the mask folding opening 4, and the mask folding plate 5 is used to fold the flat masks 9 into foldable flat masks 10. The so-called foldable flat mask 10 is to fold the flat mask 9 in half. The shaping conveying device 6 can adopt two parallel belt conveyors, which are used to transport the foldable flat masks 10 downward, and baffles are provided outside the belt conveyors.

[0040] As another solution, when the belt conveyor is not adopted, a shaping channel can be used. The so-called shaping channel is the channel through which the folded flat mask 10 runs. In this solution, the length of the mask folding plate 5 needs to be designed longer, and the folded flat mask 10 is directly pushed into the area of the discharging device 8 by the mask folding plate 5.

[0041] Preferably, the feeding and conveying device 2 is a belt conveyor, and the upper surface of the supporting table 3 is flush with or lower than the conveying surface of the belt conveyor; the mask folding opening 4 is a strip-shaped hole, and the mask folding plate 5 is a straight plate. The shaping conveying device 6 includes two symmetrically arranged belt conveyors. There is a mask conveying channel between the two belt conveyors, and the mask conveying channel is located below the mask folding opening 4; the two belt conveyors cooperate to convey the folded mask.

[0042] Further, a discharging device 8 is provided at the output end of the shaping conveying device 6 or the shaping channel.

[0043] Further, the discharging device 8 includes a horizontal pushing mechanism 81, a telescopic baffle mechanism 82 and a discharging chute 83; the telescopic baffle mechanism 82 includes a telescopic baffle rod 82.1 or a telescopic plate, and the telescopic baffle rod 82.1 or the telescopic plate is driven by a second driving device 82.2 to reciprocate, and the telescopic baffle rod 82.1 or the telescopic plate penetrates through the discharging chute 83; the horizontal pushing mechanism 81 cooperates with the telescopic baffle rod 82.1 or the telescopic plate.

[0044] The horizontal pushing mechanism 81 includes a first driving device 81.1, and the first driving device 81.1 is used to drive the push plate 81.2 to reciprocate, and the push plate 81.2 cooperates with the telescopic baffle rod 82.1 or the telescopic plate.

[0045] The folding driving device 7, the first driving device 81.1 and the second driving device 82.2 are cylinders, oil cylinders or electric push rods.

[0046] The horizontal pushing mechanism 81 is used to push the folded flat mask 10 into the discharging chute 83. When the number of folded flat masks 10 is small, the telescopic baffle mechanism 82 can be used for baffle.

[0047] In a preferred solution, the folding method of the folding device of the folded flat mask includes the following steps:

[0048] S1: Use the feeding and conveying device 2 to continuously transport the flat mask 9 to the supporting table 3, and each time one flat mask 9 is transported above the mask folding opening 4 on the supporting table 3;

[0049] S2: Use the folding driving device 7 to drive the mask folding plate 5 to move downward, and use the cooperation of the mask folding plate 5 and the mask folding opening 4 to fold the flat mask 9;

[0050] S3: The mask folding plate 5 continues to move downward, feeding the folded flat mask 10 into the shaping conveyor device 6 or the shaping channel;

[0051] S4: When using the shaping conveyor device 6, use the shaping conveyor device 6 to transport the folded flat mask 10 downward, and use the push plate 81.2 of the lateral pushing mechanism 81 to push the folded flat mask 10 into the discharge chute 83. At this time, the telescopic stop bar 82.1 or the telescopic plate is located in the discharge chute 83 and is used to block the folded flat mask 10;

[0052] When using the shaping channel, use the mask folding plate 5 to directly push the folded flat mask 10 into the working area of the lateral pushing mechanism 81; then use the push plate 81.2 of the lateral pushing mechanism 81 to push the folded flat mask 10 into the discharge chute 83. At this time, the telescopic stop bar 82.1 or the telescopic plate is located in the discharge chute 83 and is used to block the folded flat mask 10;

[0053] S5: When there are fewer folded flat masks 10 in the discharge chute 83, use the telescopic stop bar 82.1 or the telescopic plate to block the folded flat mask 10 to prevent the folded flat mask 10 from tipping over; when the number of folded flat masks 10 increases, retract the telescopic stop bar 82.1 or the telescopic plate outside the discharge chute 83.

[0054] Further, in step S1, the mask folding opening 4 is located at the middle position of the flat mask 9.

[0055] As Figures 8 - 11 shown, a folded flat mask includes a mask body 11 and ear loop wires 12 provided on both sides of the mask body 11. The mask body 11 is composed of a surface layer, an intermediate layer, a bottom layer, and a nose clip strip. The mask body 11 is a folded mask body, and the ear loop wires 12 are folded inside the mask body 11.

[0059] Embodiment 2

[0060] As Figure 10 shown, the mask body 11 is a 1 / 4 folded mask body formed by folding along the vertical central axis 13 of the mask body 11 first and then folding along the horizontal central axis 14, and its folding direction is that the bottom layer of the mask body 11 is located inside.

[0061] Example 3

[0062] As Figure 11 shown, the mask body 11 is a roll-shaped folded mask body formed by first folding along the vertical central axis 13 of the mask body 11 and then folding horizontally multiple times. The folding direction is that the bottom layer of the mask body 11 is located inside.

[0063] For the folded flat mask provided by the present invention, due to the folded manner, the volume of the required packaging bag is reduced during packaging. When the user takes it out and wears it, only the surface layer of the mask body 11 needs to be contacted, and the bottom layer of the mask will not be contacted. The problems of large volume of the packaging material used and easy contamination of the bottom layer of the mask can be solved; the ear strap 12 is folded inside the mask body 11, which is convenient for filling and packaging, and the ear strap 12 will not be pressed during sealing; when the present invention is opened and worn, the bridge of the nose is more three-dimensional, which is convenient for wearing and arranging.
