Through the upper and lower feeding transmission channels, it is effectively ensured that the mask raw materials enter the designated process of mask processing in an orderly manner for processing, thereby ensuring the orderliness of the equipment feeding.

[0034] The lower frame 9 is provided with a first mask processing mechanism 13, a second mask processing mechanism 30, a third mask processing mechanism 38, a fourth mask processing mechanism 55 and a discharging frame seat 58 in sequence from the feeding end to the discharging end. The discharging frame seat 58 includes a discharging conveying device, which is used to orderly send the formed masks to the collection box one by one. A synchronous belt power transmission device 59 is also provided at the bottom of the lower frame 9. The synchronous belt power transmission device 59 is provided to provide transmission power for each component in the overall equipment to ensure that the equipment is processed synchronously; at the same time, it is ensured that each formed mask is processed in sequence by the first mask processing station, the second mask processing station, the third mask processing station, the fourth mask processing station and other processing stations before being discharged from the discharging station, so as to ensure the high quality of the formed masks and the high production efficiency of the equipment.

[0035] The upper frame 8 is provided with an ear band transmission mechanism 10; the ear band transmission mechanism 10 is located above the second mask processing mechanism 30 and the third mask processing mechanism 38; the ear band transmission mechanism 10 is provided with an ear band folding plate 11, and transmission rollers 12 are provided on both sides of the ear band folding plate 11; the discharge end of the ear band transmission mechanism 10 is connected to the ear band feeding end of the third mask processing mechanism 38. In actual use, the ear band raw material is transmitted to the ear band folding plate 11 through the transmission roller 12, and the middle part of the ear band raw material is folded and formed by the folding and forming structure of the ear band folding plate 11, and then transmitted to the ear band feeding end of the third mask processing mechanism 38 through the transmission roller 12.

[0036] In this embodiment, the first mask processing mechanism 13 includes a nose bridge strip cutting mechanism 14 and a first mask forming mechanism 15; the nose bridge strip cutting mechanism 14 includes a nose bridge strip transmission device 16, a nose bridge strip cutting device 17 and a rotation positioning device 18. A positioning head 19 is provided on one side of the rotation positioning device 18.

The mask body raw material feeding device 20 is located at the feeding end of the lower frame 9, and is used to convey the mask body raw material into the first mask forming folding plate 21. The first mask welding mechanism 22 includes a first ultrasonic welding device 25 and a first pressing wheel 26; both sides of the first pressing wheel 26 are provided with a convex arc 27, and regular convex blocks are neatly arranged on the convex arc 27, which is used to press the side edge of the nose bridge and the bottom edge corresponding to the side edge of the nose bridge and form a specified edge sealing shape. Both sides of the first mask forming folding plate 21 are provided with shaping plates 28 for folding the side edges of the mask body, and the inner side of the shaping plate 28 located on the side edge of the nose bridge is also provided with a nose bridge strip conveying channel 29, and the discharge end of the nose bridge strip transmission device 16 is connected to the feed end of the nose bridge strip conveying channel 29.

When the positioning head 19 rotates away from the specific angle, the nose bridge strip cutting device 17 resets, which can ensure that the nose bridge strip cutting device 17 cuts the same specified length of the nose bridge strip after each operation. In actual processing requirements, the required length of the nose bridge strip can be cut by setting the rotation efficiency of the rotating positioning device 18. The nose bridge strip can be a shaped wire or other shaped material with a fixed shaping function, which can play the role of fixing the mask on the bridge of the nose.
