Mechanical principle of the strapping machine
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 Cutting tape bonding: the guiding plate is withdrawn from the middle of the two layers of plastic tape, and at the same time, the electric ironing head is synchronously inserted between the two layers of tape,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the leader The hot head is in contact with it, melted by heat (surface), and then the electric ironing head is quickly withdrawn.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 Unpacking: The bearing plate is withdrawn from the bundled plastic band, and each collet is reset to complete the bundling.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.
