Auto-Production Line
for N95 Face Mask
One. Equipment
introduction:
This
production line realizes the fully automated production of N95 masks, which
mainly includes coil feeding, folding and pressing.
Closing,
nose bridge tendon feeding, mask forming, mask cutting, earband feeding and
welding, logo printing
Brushing,
blanking of finished products, etc., complete the entire production process
from the raw material of the coil to the finished mask.
The
produced masks are comfortable to wear, no pressure, suitable for human face
shape, filter effect up to N95 standard.
Two. Equipment
characteristics:
Using
first-line brand ultrasonic welding machine, welding quality is good, durable;
Modular,
user-friendly design and convenient maintenance;
When
the equipment is abnormal or the material is cut off, it will automatically
stop the alarm and intelligently prompt the abnormal handling operation.

Equipment
Overview:
1.1
This machine is mainly used for the automatic forming of flat masks: the whole
roll of fabric is driven by rollers after unwinding, and the fabric is
automatically folded and hemmed; the entire length of the bridge is pulled and
unrolled. Ultrasonic welding to the seal, then ultrasonic side sealing, cutting
and shaping with a cutter; conveying the mask to the two mask ear band welding
stations through an assembly line, and finally forming the mask by ultrasonic
welding; when the mask is made, The pipeline is transported to the flat belt
line for collection.
