Working principle: Place three rolls of non-woven fabric 100 on the discharge rack 1, the middle roll of non-woven fabric is filter cloth with a width of 10cm, and the non-woven fabrics on both sides are outsourcing fabrics with widths of 20CM and 10CM respectively. Layers of non-woven fabrics are stacked together, wherein the bottom layer is 20CM outsourcing non-woven fabric, the middle layer is 10CM filter non-woven fabric, and the top layer is 10CM outsourcing non-woven fabric, all aligned with the center line.

Start the equipment and start to work. After the three rolls of non-woven fabric 100 pass through the fabric welding device 2, they are ultrasonically welded, and the three layers of non-woven fabric 10 are tightly fused into one. At the same time, three welding lines 102 are formed on the surface area. After the cutter device 3, the redundant non-woven fabric edges at both edges are cut off, and the edges form two symmetrical continuous loop wave-shaped sides 104.

Then through the earband welding device 4, as shown in Figure 9, the earband line is long and continuous in the initial state, placed on the earband conveying mechanism 45, and the end of the earband line is clamped by the left rear side brake block 424D On the side wall of 425A, the ultrasonic indenter mold 423, the opening mechanism 421 and the closing mechanism 422 are all in the rising state, that is, they do not interfere with the rotation of the winding reel 425A. Under the action of the third motor 425B, the winding reel 425A reverses The clockwise rotation is 180 degrees, so that the left rear side brake block 424D in Fig. 9 turns to the position of the right front side brake block 424D in Fig. 10, and the other three brake blocks are also rotated accordingly, so that the ear strap line is at the position of the 424D brake block. Under traction, go around from the gate block 424D along the front side of the winding reel 425A to the gate block 424A, then from the gate block 424A to the gate block 424B, and then start the closing mechanism 422 to descend, when the closing frame 422A descends and touches the winding The two brake blocks 424A and 424B on the left side of the disk 425A close it, and the two brake blocks on the left side press the ear strap line tightly on the side wall of the winding disk 425A, and then the closing mechanism 422 rises back to the initial state. Then start the thread cutting device 44 to work, and cut the ear strap line in the middle of the left two brake blocks 424A and 424B to form a single-cut ear strap line 103 to be welded between the brake blocks 424D and 424A. After cutting, the thread cutting device 44 Return to the initial state, then start the first cylinder 420 to descend, and the lifting frame 426 descends together with the telescopic head of the first cylinder 420 under the action of gravity, and the winding reel 425A also descends along with it. When the winding reel 425A descends and touches the mask cloth , the two ultrasonic pressure head molds 423 are still suspended in the air, the telescopic head of the first cylinder 420 continues to descend, and simultaneously starts the gate opening mechanism 421 to press down, and after the gate opening frame 421A touches and presses the gate opening lever 424-1, as shown in Figure 10 , open the front left brake block 424A and the right two brake blocks 424D and 424C at the same time, the single ear belt line 103 is free from the constraints of the brake block, and then the gate opening mechanism 421 rises back to the initial position, and at this time it is connected to the first cylinder 420 The ultrasonic indenter mold 423 of the ultrasonic pressure head is pressed down on the mask cloth, and the two ends of the single ear strap line 103 are ultrasonically pressed on the mask cloth. After the welding is completed, the first cylinder 420 rises back to the initial state, and the left rear side brake block 424B keeps the gate closed all the time, so that the incoming wire end of the raw material of the ear strap line is tightly pressed against the side wall of the gate block 424B and the winding reel 425A, and then repeat the above steps to complete the welding of the ear strap wire of the next mask.

So far , the earband line 103 is ultrasonically welded to the side edges of the adjacent two protrusions, and then the mask non-woven fabric passes through the folding device 5, and the non-woven fabric is folded in half with the center line as the folding line. After folding in half, the mask non-woven fabric Placed on a vertical plane, and then passed through the forming welding device 6, the closed folded edge is ultrasonically welded into an arc-shaped welding line 101 (C-shaped), and then passes through the forming cutter device 7, and the mask body is along the outer edge of the arc-shaped welding line It is cut by a forming cutter, formed into a single finished mask, and then transported out of the assembly line through the discharge conveyor device 8. All the above power output devices are connected to the PLC controller. Under the control of the PLC preset program, the entire equipment realizes full automation Continuous production.
