LHB-450 Fully Automatic Roll-fed Square Bottom Paper Bag Making Machine -Tianfuchenglai-25
LHB-450 Fully Automatic Roll-fed Square Bottom Paper Bag MachineLHB-450 Fully Automatic Roll-fed Square Bottom Paper Bag MachineLHB-450 Fully Automatic Roll-fed Square Bottom Paper Bag Making Machine
High Speed Square Bottom Kraft Paper Bag Machine
Features:
1. Touch screen is adopted for input control and machine status display,
so as to finish machine
correction easily.
2. Equipped with originally imported SIEMENS electrical system and servo motor drive, to make the
machine run steadily.
3. Germany SICK photoelectric detector is used to track
the material to be printed,
reduce the
adjusting time and improve
production efficiency
4. Separate single-station unwinding
rollstand with hydraulic
lifting device; Convex-type inflatable shaft
for loading material (or shaftless loading);
Magnetic powder brake for unwinding
and automatically
constant tension controller for unwinding tension
control; EPC web guide control
system for material
alignment; alarm function for reminding replacing
material and stopping-machine device for
detecting material broken.
5. The handle making component is an independent
machine, which is driven by servo motor and
synchronized with the main motor; handle length is adjustable according to bag size.
6. The cutting and gluing of paper handles
are controlled by servo
motors, as synchronous as the tub
cutting of the main machine; contact
rollers transfer pattern
is adopted in gluing
paper handles;
vacuum suction pattern is adopted
in transferring handles onto conveyer
belt; handles are
compressed onto the paper web with a series
of pneumatic rollers,
to ensure the pasting strength.
7. Adjustable forming mould structure (side sealing is above the forming mould);
automatic
glue-spraying device with automatic
disengaging function is used for side gluing.
8. Rotary serrated cutter (or flat-blade cutter) with elliptical
gears is used for cutting; the cutting length
can be corrected by SICK photoelectric detector; Multi-layers bottom forming
drum, center grippers,
second tuck clamps,
and drum grippers
are adjustable for ease of changeover; automatic
disengaging function
(bottom gluing is prevented for empty feeding
to avoid contamination to the
surface of the drum).
9. Paper bags are delivered by belt, and collected at side workbench, which is easy for operations;
automatic counting function.
10. Automatic lubricating oil supply system.
