The front knife lower belt pressing head 313 is matched with the front knife upper belt pressing head 411 of the front knife to carry out belt pressing work; the middle knife lower grinding head 314 is matched with the middle knife upper grinding head 106 for bonding; the rear knife lower belt pressing head 315 is matched with the rear knife upper belt pressing head 504 of the rear knife to carry out belt pressing work.

For better understanding, the utility model discloses, following is to the theory of operation of the utility model make a complete description:

as shown in fig. 12 (in the drawing, the arrow indicates the crossing direction of the strap, and the tightening direction is the opposite direction of the arrow), when the strap is packed, the strap is fed out from the tightening part, and passes through the strap passing hole 410 of the front knife, the strap passing cavity between the middle knife upper grinding head 106 and the middle knife lower grinding head 314, and the strap passing cavity between the rear knife upper press head 504 and the rear knife lower press head 315, and then passes through the strap passing cavity between the front knife upper press head 411 and the front knife lower press head 313, and the strap passing cavity between the middle knife upper grinding head 106 and the middle knife lower grinding head 314, and stops after the strap is in place, and at this time, the strap passing cavity between the middle knife upper grinding head 106 and the middle knife lower grinding head 314 has two layers of overlapping straps.

After the strapping tape is in place, the strapping tape head needs to be pressed by the upper front-knife strapping head 411 and the lower front-knife strapping head 313 of the front-knife mechanism 4, so as to tightly press the strapping tape head. Specifically, the front knife cylinder 401 operates to drive the front knife pressing connecting rod 402 to move, so that the front knife pressing connecting rod 402 rotates around the front knife mounting hole 408, the front knife 403 connected to the front knife connecting hole 407 is pressed downwards, the front knife 403 moves downwards in the front knife slot, and the front knife upper pressing head 411 at the bottom end of the front knife 403 presses the strapping tape on the front knife lower pressing head 313 to perform the pressing operation.

After the front knife is pressed, the tightening power part is tightened, and after the strapping tape is tightened, the rear knife mechanism 5 is started to press the tail part of the strapping tape (after the upper strapping tape is cut by the cutter 105, the tail part of the strapping tape is formed). Specifically, the rear knife cylinder 501 drives the rear knife pressing connecting rod 502 to move, so that the rear knife 503 connected with the rear knife pressing connecting rod 502 moves downwards in the rear knife slot, the rear knife upper pressing head 504 at the bottom end of the rear knife 503 presses the strapping tape on the rear knife lower pressing head 315, the pressing operation is performed, and the tail of the strapping tape is pressed.

After the rear knife mechanism 5 presses the tail part of the strapping tape, the middle knife mechanism 1 carries out bonding and cutting-off work. Specifically, the middle knife cylinder 10 drives the knife rest 103 to move downward, and further drives the cutter 105 to cut off the overlapped upper strapping tape. Meanwhile, the motor 101 drives the eccentric cam 102 to rotate, the eccentric cam 102 rotates in the vibration hole 108 of the vibration rod 104, and then the vibration rod 104 is driven to reciprocate at a high speed by taking the rotation shaft as a center, so that the vibration rod swings and vibrates at a high speed, and the high-speed vibration is transmitted to the upper grinding head 106 at the bottom end of the vibration rod 104, so that a plurality of protrusions on the bottom surface of the upper grinding head 106 generate high heat through high-speed friction vibration, and then the upper and lower layers of overlapped strapping tapes are hot-melted and firmly adhered together in a penetrating manner. Cutting and bonding are carried out simultaneously and are finished at one time.

After the cutting and bonding work of the middle cutter mechanism 1 is finished, the cylinders of the front cutter mechanism 4, the middle cutter mechanism 1 and the rear cutter mechanism 5 return to enable the front cutter, the middle cutter and the rear cutter to return.

After the knives return to the original positions, the tape removing cylinder 302 drives the tape removing connecting rod 303 to move, so that the tape removing connecting rod 303 rotates by taking the hinge hole 309 as a center, and further the base 301 at the front end of the tape removing connecting rod 303 also rotates by taking the hinge hole 309 as a center, so that the base 301 inclines, and the strapping tape automatically falls off from the inclined base 301 under the action of self pretightening force to automatically remove the tape.

The embodiments of the present invention have been described in detail, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and the equivalents or substitutions are included in the scope of the present invention defined by the claims.
