The entire roll of fabric is unrolled and then combined by rollers.
The fabric is unfolded through mechanical folding and the nose
bridge is pulled and unrolled. It is cut to length and then
introduced into the edged fabric. It is ultrasonically welded to
the seal on both sides and then ultrasonically sealed , Cutting and
forming by a cutter; the mask body is divided into two ear band
spot welding machines by a one-to-two dispenser, and the ear bands
are ultrasonically welded; the number is set for stacking and
receiving.
Equipment environmental requirements:
1. The ambient temperature is required to be between 15 and 35 ° C.
2. The humidity requirement is 40% ～ 80%, no condensation,
3. Power supply grid requirements: AC220V, 50Hz;
4. Power supply grid fluctuation: ± 5%, the power grid ground wire
meets international requirements. Areas with a voltage amplitude of
more than 5% should be equipped with automatic voltage
stabilization and current stabilization devices;
5. There should be no strong electromagnetic signal interference
near the installation equipment, and avoid radio transmission
stations (or relay stations) around the installation site;
6. Foundation amplitude: less than 50um; vibration acceleration:
less than 0.05g; avoid a lot of machine tools such as punching in
the vicinity;
7. Equipment space requirements to ensure smoke-free and dust-free,
to avoid serious working environments such as metal polishing and
grinding;
8. Air pressure: 86 ～ 106kpa;
9. In some environments, antistatic flooring and shielding should
be installed;
