The fully automatic folding mask machine 1000 of the present invention integrates production and testing, which not only improves production efficiency and yield rate, but also effectively avoids waste of resources in the mask production process because it can deal with production problems in a timely manner.

[0044] See also Figures 2 to 4In some optional embodiments, the nose bridge strip installation device 10 includes a nose bridge strip feeding mechanism 11 disposed on one side of the frame 110, and a nose bridge strip pushing mechanism 12, a first guide mechanism 13, a pressing mechanism 14, and a pressing guide mechanism 15 disposed on the frame 110. Specifically, the nose bridge strip feeding mechanism 11 includes a nose bridge strip material rack 111 for winding and accommodating the nose bridge strip, and the nose bridge strip is transferred from the nose bridge strip material rack 111 to the nose bridge strip guide assembly 112, and the nose bridge strip is transferred to the nose bridge strip pushing mechanism 12 along a certain route through the nose bridge strip guide assembly 112. The nose bridge strip pushing mechanism 12 is provided with a feeding member 121 for guiding feeding, and the nose bridge strip is transferred from the feeding member 121 to the receiving member 122, and the receiving member 122 is connected to a cutting assembly 123, and the cutting assembly 123 includes a cutting member 1231 and a cutting cylinder 1232. When the nose bridge strip is fed to the first preset length, that is, the length of the nose bridge strip in the container 122 has reached the required length for the use of the KN95 mask, the cutting cylinder 1232 is actuated to enable the cutting piece 1231 to cut the nose bridge strip of the first preset length located in the container 122. In this embodiment, the cutting assembly 123 is located below the container 122. Then, the pushing assembly 124 located at one end of the container 122 is actuated to push the cut nose bridge strip. The pushing assembly 124 includes a pushing piece 1241 and a pushing cylinder 1242. The pushing cylinder 1242 is actuated to enable the pushing piece 1241 to push the nose bridge strip in the container 122 to cooperate with the cloth at the first guide mechanism 13, and to enable the nose bridge strip to be located between the multiple layers of cloth. A plurality of first guide rollers 101 for guiding are provided on the nose bridge strip mounting device 10, and the multiple layers of mask cloth on the feeding device 200 are transmitted to the first guide mechanism 13 through the plurality of first guide rollers 101. At the first guide mechanism 13, the bridge of the nose strip is pushed into the multi-layer mask fabric by the bridge of the nose strip pushing mechanism 12. Under the action of the conveying device 120 inside the frame 110, the fabric with the bridge of the nose strip is conveyed from the first guide mechanism 13 to the pressing mechanism 14, which presses the bridge of the nose strip between the fabrics and forms the mask body. The pressing mechanism 14 is a mechanism with ultrasonic welding, which forms the shape of the mask body on the multi-layer fabric by ultrasonic welding, and forms the bridge of the nose strip inside the mask body. The pressing guide mechanism 15 is used to shape the formed mask body and guide it to the next station.

[0045] See also Figure 5 and Figure 6In some optional embodiments, the ear wire welding device 20 includes a wire feeding mechanism 21, a wire taking mechanism 22, a wire cutting mechanism 23 and a wire welding mechanism 24. Specifically, the wire feeding mechanism 21 is located on the frame 110, and is used to guide and transmit the ear wire to the wire taking mechanism 22. The wire taking mechanism 22 includes a rotating wire taking component, which clamps the ear wire and drives the ear wire to rotate. The length of the ear wire is exactly the second preset length every time the wire taking component rotates. It can be understood that the second preset length is the length of the ear wire required to be worn by the KN95 mask. After the wire taking component rotates, the wire cutting mechanism 23 cuts the ear wire according to the second preset length. The wire taking mechanism 22 can be lifted and lowered to cooperate with the wire welding mechanism 24. The wire taking component cooperates with the mask body on the frame 110 after the cut ear wire, and the ear wire and the mask body are welded into shape by the wire welding mechanism 24.

[0046] See also Figure 7 In some optional embodiments, the ear wire tension test device 30 includes a material pressing mechanism 31 and a wire pulling mechanism 32. The material pressing mechanism 31 is used to press the mask body so that the wire pulling mechanism 32 can pull the ear wire. The wire pulling mechanism 32 is arranged on the frame 110 in a manner that can be lifted and slid. The ear wire tension test device 30 is located after the ear wire welding device 20. Since the ear wire welding device 20 of the previous process is not welded in place, the ear wire of the mask is easily separated from the mask body during use, so that it cannot be used. In the prior art, the ear wire tolerance is generally tested by manual pulling. Manual pulling not only has uneven force, but also has a large workload. By setting up the ear wire tension test device 30, the ear wire welding of the mask can be fully inspected, and the welding position of the previous process can be adjusted in time to improve production efficiency and yield rate. Specifically, after the mask body is welded, it is transmitted to the ear wire tension test device 30 by the conveying device 120. The pressing mechanism 31 on the ear wire tension testing device 30 presses the mask body, and simultaneously pulls the ear wires on the mask body through the wire pulling mechanisms 32 located on both sides to detect the ear wire's tolerance to tension. Among them, the wire pulling mechanism 32 includes a sliding assembly 322 and a wire pulling assembly 321 arranged on the frame 110, and the wire pulling assembly 321 can be arranged on the sliding assembly 322 to slide up and down through a cylinder or a motor.

Among them, the sponge strip feeding mechanism 41 includes a sponge strip material rack 411, a sponge strip guide assembly 412 and a sponge strip guide wheel 413.

The sponge strip roll is wound on the sponge strip material rack 411, and the sponge strip roll is guided and transported by the sponge strip guide assembly 412, and finally the sponge strip roll is guided to the sponge strip taking mechanism 42 by a sponge strip guide wheel 413. The sponge strip picking mechanism 42 is located below the mounting mechanism 43. Specifically, the sponge strip picking mechanism 42 includes a sponge strip picking part 421, a sponge strip placing part 422, and a sponge strip lifting assembly 423.

When the mask body on the frame is in place, the sponge strip placing part 422 drives the sponge strip to rise under the action of the sponge strip lifting assembly 423 and contacts the sponge strip taking part 421, so that the sponge strip taking part 421 can peel off the sponge strip on the roll, and the sponge strip is attached to the inner surface of the mask body under the cooperation of the sponge strip taking part 421 and the mounting roller 431. The mounting roller 431 is located in the frame 110, and the mounting roller 431 is provided with a second guide roller 432 for guiding at both ends. The mask body is guided to the mounting roller 431 through the second guide roller 432, and the other second guide roller 432 guides the mask body with the sponge strip attached to the next process.
