Both the first contact rod 305 and the second contact rod 306 are located at the end near the auxiliary support 202, but the second contact rod 306 is located on the track unit 304a, while the first contact rod 305 is located on the corrugated cardboard box.

[0038] When binding, the frame 401 is pushed out. At this time, the drive motor controls the winding drum 409 to tighten the pull wire 408a. At this time, the locking rod 407 cannot be separated from the groove 404 at the end near the groove 404, while the end near the slot 406 is a free end and can be released from the slot 406.

[0039] As the frame 401 moves forward, the locking rod 407 rotates around the end of the locking rod 407 closest to the groove 404, obstructed by the first contact rod. The lower end of the locking rod 407 rotates, allowing the corrugated cardboard box to be inserted into the space formed by the locking rod 407, the frame 401, the first connecting rod 402, and the second connecting rod 403. Meanwhile, the winding drum 409 continues to rotate, pulling the locking rod 407 to rotate in the opposite direction, causing the lower end of the locking rod 407 to engage in the slot 406. As long as the winding drum 409 remains stationary, the corrugated cardboard box cannot detach from the aforementioned space.

[0040] Furthermore, the pull rope 502 includes several support blocks 502a that are connected end to end. The front end of the support block 502a is provided with an ear plate.

[0041] Operation process: During binding, the drive ring 303 is rotated, causing the pull rope 502 to move, which in turn moves the pull block 203c forward, pushing out the frame 401. At this time, the drive motor controls the winding drum 409 to tighten the pull rope 408a. At this time, the locking rod 407 cannot be separated from the groove 404 at the end near the groove 404, while the end near the slot 406 is a free end and can be disengaged from the slot 406. As the frame 401 moves forward, the locking rod 407... 07. With the first contact rod 305 obstructing the rotation, the locking rod 407 rotates around the end near the groove 404. At this time, the lower end of the locking rod 407 rotates, allowing the corrugated cardboard box to be inserted into the space formed by the locking rod 407, the frame 401, the first connecting rod 402, and the second connecting rod 403. Meanwhile, the winding drum 409 continues to rotate, pulling the locking rod 407 to rotate in the opposite direction, causing the lower end of the locking rod 407 to engage in the slot 406. At this point, only the winding drum... 409 remains stationary, preventing the corrugated carton from detaching from the aforementioned space. At this point, the strapping, propelled by the rear elastic piece 402b, pops out and wraps around the corrugated carton. Then, the locking rod 407 reverses its movement, causing the adhesive heating element to apply adhesive to the end of the strapping and seal it, completing the binding. To release the corrugated carton, first retract the first contact rod 305. Then, the drive motor reverses its rotation to rotate the winding drum 409, fully releasing the pull cord 408a. At this point, the locking rod 407... Once the corrugated box is near the groove 404, it can be disengaged. Push and pull the frame 401 forward again. At this time, the second contact rod 306 is in the retracted state. After the locking rod 407 moves past the position of the second contact rod 306, the second contact rod 306 rises, so that the second contact rod 306 obstructs the locking rod 407. At this time, the locking rod 407 rotates around the groove 406 as the rotation center, and then the corrugated box can be disengaged. Then the second contact rod 306 retracts, and the corrugated box falls onto the track unit 304a.
