The present invention carries out non-woven fabric and bridge of nose strip feeding through material discharging mechanism 110, and multi-layer non-woven fabric and bridge of nose bridge enter printing mechanism 130 through material discharging mechanism 110, to print on the surface of non-woven fabric, after printing, pass through fixed nose bridge The bar mechanism 140 welds the bridge of the nose bar between the multi-layer non-woven fabrics by means of ultrasonic welding, and then forms a pattern on the non-woven fabric through the pattern mechanism, and cuts off the waste at the edge of the pattern by the cutting mechanism, and passes through the waste collecting mechanism 180 Reclaim the corner waste that produces after cutting, and the final mask finished product is unloaded by the discharge mechanism 170. The production process of masks has a high degree of automation, high work efficiency, and the quality of the masks produced is good.

Working principle of the present invention is:

First, the discharge mechanism 110 discharges the material, and the five material strips are respectively output through the five discharge shafts 112, and then the five material strips are transported to the subsequent manufacturing mechanism through the five transmission units 114, and the nose bridge strips are output through the discharge roller 115 To the subsequent manufacturing mechanism, during this process, when the tension of a certain strip is small, the horizontal position of the discharge shaft 112 can be adjusted through the adjustment unit 113. The specific adjustment process is that the staff shakes the handle 113a, and the handle 113a drives the transmission rod 113b Rotate, the transmission rod 113b drives the transmission chain to move, and the transmission chain drives the installation platform 116 and the discharge shaft 112 positioned on the installation platform 116 to slide along the slide rail 111b, so that the material strip is stretched straight;

Then, the material strip enters the printing mechanism 130, and signs such as patterns and characters are printed on the non-woven fabric;

Then, after printing, the material strip and the nose bridge strip enter the fixed nose bridge strip mechanism 140, so that the nose bridge strip is welded between the non-woven fabrics;

Then, enter the first pattern mechanism 150a to form a pattern at one end of the non-woven fabric;

Then, enter the first cutting mechanism 160a to cut off the corner waste beside the pattern of the non-woven fabric. The specific cutting process is that the material strip moves to the fine-tuning unit 163, enters the gap between the adjustment fixing rod 163c and the arc plate 163d, The adjustment handle 113a drives the vertical rod 111a to slide up and down through the transmission assembly to change the height of the adjustment fixed rod 163c and the arc plate 163d, thereby changing the position of the material strip, ensuring that the position of the material strip enters the cutting unit 161 accurately, and the finely adjusted material The strip enters the cutting unit 161, and the waste material next to the decorative pattern of the strip is cut off by the cutting unit 161. During the cutting process, the front end of the strip enters the pulling unit 162. When the strip passes through the pulling wheel 162e and the pulling rubber wheel 162d When there is a gap between them, the power assembly 162g drives the pulling rubber wheel 162d installed between the two first sliders 162b and the pulling wheel 162e installed between the two second sliders 162c to move synchronously, and then drives The material strip moves so that the material strip is straightened to ensure that the tension is constant when the material strip is cut by the cutting unit 161, which is conducive to improving the cutting accuracy. The material strip after cutting by the cutting unit 161 enters the subsequent folding mechanism 190a on both sides. The corner waste that produces simultaneously is taken to the waste collection mechanism 180 .

Then, the scrap collection mechanism 180 recycles the corner scraps. The specific recycling process is that the scraps are transported to the scrap collection mechanism 180, enter the scrap puller 185, and enter the discharge unit 187 with the movement of the scrap puller 185 under the action of the power unit. Through the rotating shaft, it enters the driven wheel sleeved outside the driven shaft. During the rotation of the driven wheel, the guide ring guides the waste, so that the waste is discharged through the guide ring.

While collecting the waste, the non-woven fabric is calibrated by the fine-tuning unit 163 and then enters the two-side folding mechanism 190a to fold both sides of the non-woven fabric.

Then, the folded non-woven fabric enters the second pattern mechanism 150b after being pulled by the pulling unit 162, so as to form a pattern in the middle of the non-woven fabric.

Then, the non-woven fabric formed with a pattern in the middle is fine-tuned by the fine-tuning unit 163 and then enters the half-folding mechanism 190b to fold the two sides of the non-woven fabric in half to form a middle crease.

Then, the non-woven fabric with creases in the middle is pressed into a plane by the cloth pressing mechanism 190c, which is convenient for ensuring storage.

Then, the non-woven fabric folded in half passes through the reversing mechanism 190d, and the position of one end is exchanged with the other end, so that the other end of the non-woven fabric can be patterned.

Then, the third pattern mechanism 150c forms a pattern on the other end of the nonwoven fabric to obtain the finished mask.

Then, the second cutting mechanism 160b cuts off the waste material at the edge portion of the other end, and the second waste material collection mechanism 180b recycles the waste material.

Finally, the finished mask is discharged through the discharge mechanism 170.
