The SED-450-8KDB-A is driven by full servo motors, with PLC
control, stepless speed regulation, and a human-machine interface
for operation. It features low noise and simple, user-friendly
operation.
Powered by five sets of servo motors, each station—including
vertical sealing, horizontal sealing & easy-tear notch, secondary
horizontal sealing & batch number printing, dotted-line cutter, and
cutting knife—is equipped with an independent servo motor. The
one-time completion of multi-station processes enhances the
machine’s automation level and simplifies operation.
The alignment system adopts imported Banner (a U.S. brand)
components, ensuring accurate alignment with a deviation range of
0.5mm to 1mm.
Bag length can be adjusted freely: simply input the desired bag
length on the touchscreen, and all stations will automatically
adjust and align—no manual adjustment of mechanical parts is
required. The adjustment takes less than 1 minute, saving both
materials and time.
The batch number printing device is driven by an independent servo
motor, synchronized with the main machine. It delivers clear batch
numbers with accurate positioning and easy replacement.
The easy-tear notch blade is directly installed on the horizontal
sealing mold, ensuring absolutely accurate notch positioning
without the need for adjustment.
Omron intelligent temperature controllers are adopted for
temperature control, with a sealing temperature setting range
deviation of ±1°C. The heating tubes for vertical and horizontal
sealing use a single heating system divided into three sections;
section-by-section adjustment ensures more uniform temperature in
each section and better sealing effect, with a deviation range of
approximately ±1°C.
With servo motor transmission, cam positioning, and synchronization
with the horizontal sealing mold, the machine uses triangular
measuring cups for metering. The cup volume supports both
individual and overall adjustment, ensuring high metering accuracy,
low noise, and easy disassembly and cleaning—effectively solving
the problem of fine powder leakage in the feeding mechanism.
For film edge correction (left and right), a Taiwanese optical
sensor (groove-type) device is used. It is driven by an independent
motor to automatically control the left-right correction of the
rolled film, featuring convenient operation and high accuracy with
a deviation range of 0.5mm to 1mm.
PLC control, servo motor drive, photoelectric tracking, and an
automatic correction system ensure automatic alignment of
double-sided printed patterns on packaging bags. When adjusting the
bag length, only 2–3 bags are wasted for automatic alignment
correction.
The hopper’s top cover and the hopper itself can be sealed and
easily opened. The top cover is equipped with a feeding port (80mm
in diameter), which can be connected to the discharge port of a
vacuum feeder for automatic feeding (Note: Vacuum feeder model
QVC-1).
The conveyor belt is driven by an independent motor with adjustable
speed.
The equipment’s materials meet GMP requirements: all parts in
contact with materials are made of 316L stainless steel; other
outer cover parts are either made of 304 stainless steel or undergo
surface anti-corrosion treatment.
This equipment can be modified to match an automatic production
line, supporting processes including automatic feeding, bag making,
material adding, batch number printing, easy-tear notch creation,
punching & cutting, bag picking, arranging, single-bag weighing,
defective product rejection, bag stacking, bag counting, further
rejection, instruction manual folding, carton forming, carton
opening, bag cartoning, batch number printing on cartons, and
carton sealing.
It is suitable for packaging loose, non-sticky powdery and granular
materials in industries such as pharmaceuticals, food, pesticides,
and daily chemicals, including examples like small pills, white
sugar, salt, cereal, seeds, and Chinese medicine granules (e.g.,
cold granules).
