[0036] Example 1:

[0037] The existing conventional mask sizes are 14.5*9cm for children, 17.5*9.5cm for adults, and 19.5*9.5cm for extended lengths. In order to use the same equipment to produce masks of three sizes, the following are provided: Figure 1-5 The fully automatic interchangeable flat mask machine shown includes: a main body 1, a feeding mechanism 2, an ear strap welding mechanism 3, a conveying mechanism 4, a sterilization box 5, a sealing mechanism 6, a storage mechanism 7, a control system 8, and an electrical system 9.

At the lower part, the end of the rotating rod 34 has a clamping groove, in which a clamping claw 35 is installed; the main body 1 has a first sliding groove 37, on which a first slider 36 is installed, and an earband clamp 38 is installed on the first slider 36. A knife holder 312 is installed at one end of the first sliding groove 37 in the direction of the earband clamp 38, and a cutting knife 311 is installed on the knife holder 312. A wire feeding frame 310 is installed next to the knife holder 312, and an earband feeding mechanism 39 is installed next to the wire feeding frame 310. The spot welding mechanism 313 is installed on the first supporting frame 32. The earband welding mechanism 3 is used to weld the earband to the mask. The position of the clamping claw 35 can be adjusted in the clamping claw groove, and the length of the earband can be adjusted.

[0041] There are two ear band welding mechanisms 3, which are relatively installed on both sides of the first conveyor belt 41. The ear bands on both sides of the mask can be welded at the same time.

[0042] The sterilizing box 5 is above the second conveyor belt 42, and an ultraviolet sterilizing lamp 51 is arranged in the sterilizing box 5. The sterilizing box 5 is used for sterilizing the mask before sealing.

[0043] The sealing mechanism 6 includes a second support frame 61, a feed roller 62, a pressure roller 63, a plastic sealing platen 64, and a rolling blade 65. The feed roller 62 is mounted on the second support frame 61. Two pressure rollers 63 are installed at the entrance of the third conveyor belt 43 and are tangential to the third conveyor belt 43. The plastic sealing platen 64 is mounted on the second support frame 61 and above the third conveyor belt 43. The rolling blade 65 is installed at the exit of the third conveyor belt 43. The sealing mechanism 6 is used to plastic seal the masks. Each rotation of the rolling blade 65 is counted and fed back to the control system 8.

[0044] The storage mechanism 7 includes a second chute 71, a second slider 72, and a storage box 73. The second chute 71 is located below the exit of the third conveyor belt 43 and is perpendicular to the third conveyor belt 43. The second chute 71 contains several second sliders 72, each of which has a storage box 73 placed on it. The second chute 71 can accommodate multiple second sliders 72 and storage boxes 73. When one storage box 73 is full, the next storage box 73 is automatically used to store the items, improving storage efficiency.

[0045] The control system 8 is electrically connected to the electrical system 9 .

[0046] The electrical system 9 is electrically connected to the feeding mechanism 2 , the ear band welding mechanism 3 , the conveying mechanism 4 , the sterilization box 5 , the sealing mechanism 6 , and the storage mechanism 7 .

[0047] Working Principle: The position of the partition 45 and the baffle 24 on the first conveyor belt 41 are first set according to the type of mask to be processed to achieve the positioning of the mask. The unprocessed masks are placed in the loading rack 21. The masks will slide out from the loading rack 21 one by one. The masks have a certain degree of hardness and fall onto the first conveyor belt 41. They are limited by the partition 45 and baffle 24 to ensure that the position of the masks dropped is consistent each time.

[0048] The mask is transported to the bottom of the earband welding mechanism 3 via the first conveyor belt 41. The earband feeding mechanism 39 delivers the earband to the wire feeder 310. The first slider 36 slides in the first chute 37 toward the wire feeder 310. The earband clamp 38 on the first slider 36 clamps the earband on the wire feeder 310 and pulls the earband to the appropriate length. The two clamps 35 clamp the ends of the earband, and the cutting knife 311 cuts the earband. The vertical motion mechanism 33 drives the clamps 35 upward, and the rotating rod 34 rotates the clamps 35 above the mask, pressing the ends of the earband onto the mask. The spot welding mechanism 313 welds the earband to the mask.

[0049] When the mask reaches the exit of the first conveyor belt 41, the pressing plate 46 flattens the earbands onto the mask. The mask then falls onto the second conveyor belt 42. After being sterilized by ultraviolet light in the sterilization chamber 5, it moves to the entrance of the third conveyor belt 43. One laminating tape is fed from the feed roller 62 to the underside of the pressure roller 63, while the other laminating tape is passed along the third conveyor belt 43 to the underside of the pressure roller 63. Once on the third conveyor belt 43, the mask passes between the two laminating tapes. The laminating pressing plate 64 flattens the mask and seals it securely. The rolling cutter 65 then cuts the laminating tape.

[0050] The plastic-sealed masks fall into the storage box 73. When one storage box 73 is full, the second slider 72 slides and the next storage box 73 is automatically used for storage.
