Product Details
Textile Fabric Test Equipment Industrial Metal Detectors Optical
Infrared Emitters Automatic
Introduction
Shoes head needle machine Optical Infrared emitters Needle Detector
Machine of thick material and thin material, display of the positions of
broken needles and scrap iron in an object being detected for
facilitating the finding of the broken needles of operators,
automatic return of object to be detected, automatic start-up, once
switch startingfir each working stage, a power utilization system
capable of stopping the machine five minutes after no-load
operation, power and money conservation, power utilization safety
protection, great popularity among customers.
Features:
Needle is extremely sensitive, good stability, the needle will
automatically detect the alarm and return matches in production
line
working principle
Upper and lower head of the magnetic coil by the access needle and
the machine's power to work together to form a magnetic needle,
when iron and other substances with different properties of iron
into the needle area, it will cause a change in the local magnetic
field, and thus fluctuations in the magnetic field caused by local
instantaneous current. Perceived abnormal current will be
transferred to the control board, and set a good sensitivity
compared with the needle before; when the current value of this
change reaches or exceeds value flu needle devices in use when the
set time, machine control board will make the alarm, stop, rewind
the belt so that a series of instructions; and finally complete it
some action.
