A
strapping machine (packer) is a machine that wraps a product or package
with a strap, then tightens and fuses both ends by thermal effects or
using a material such as a buckle. The
function of the strapping machine (packing machine) is to make the
plastic belt adhere to the surface of the bundled package, to ensure
that the package is not scattered during transportation and storage, and
should be bundled neatly and beautifully.
1.
Retract the tension: a collet rises to clamp the plastic head, the belt
reversing belt is reversed, the excess plastic belt is returned to the
storage box, and the bundle is tightened. Subsequently, the robot grips the plastic strip and tightens the package to the tightness.
2. Cutting
tape bonding: the guiding plate is withdrawn from the middle of the two
layers of plastic tape, and at the same time, the electric ironing head
is synchronously inserted between the two layers of tape, and then the
second chuck is raised to clamp the other end of the plastic tape, the
cutter cuts the tape, and pushes the leader The
hot head is in contact with it, melted by heat (surface), and then the
electric ironing head is quickly withdrawn. The cutter continues to
rise. The two layers of plastic tape with the surface melted are pressed
against the bearing plate, and cooled and solidified. The two belts are
bonded (YKM-WY The machine does not have a hot head, and the friction is activated to complete the bonding).
3. Unpacking: The bearing plate is withdrawn from the bundled plastic band, and each collet is reset to complete the bundling.
4. Feeding
belt: The belt pulley rotates forward and the plastic belt is fed into
the track by the storage box, ready for the next bundle.
5. Uninstall. The
above is the process of single-bundling. When the machine is in the
interlocking state, after the feeding is completed, the retracting
tensioning program is directly entered, and the cycle is continuously
performed according to the above procedure.
The
packaged object is basically in the middle of the carton binding
machine. First, the right abutment body rises, the front end of the belt
is pressed, the belt is tightened and tied on the object, then the left
abutment body is raised, the appropriate position of the lower layer
tape is pressed, and the heating piece is extended into the two belts. In
the middle, the middle knives rise, cut the belt, and finally send the
next tying strap to the position to complete a work cycle.
Strapping
machine workflow: belt is sent to the position → received the strapping
signal → the brake is released, the main motor starts → the right top
knife rises, the right belt is placed on the skateboard → the “T” type
guide plate retreats → the proximity switch senses the retracting probe → The
main motor stops, the brake is closed → the strapping machine retracts
the motor to rotate, the belt is retracted for 0.35 seconds → the strap
is tightened and tied on the object → the main motor is started twice,
the brake is pulled → the large swing rod is pulled twice, and the strap
is tightened →The
left acrosome rises, the lower layer is pressed → the heating piece
extends into the middle of the two belts → the middle top knife rises,
the belt is cut → the middle top knife is lowered → the middle top knife
rises again, so that the two belts are firmly bonded → the middle top
knife is lowered, The
left and right top knives are simultaneously lowered → the heating
plate is reset → the skateboard is retracted → the “T” type guide plate
is reset → the proximity switch senses the belt feeding probe → the belt
feeding motor is started, the belt feeding belt is brought up → the
large pendulum rod is reset → the belt is in place, and the head is
topped to “ On
the T" type guide → proximity switch senses double probe → main motor
stops, brake pulls → the strapping machine completes a working cycle.
