[0023] Example 1:

[0024] A rope bundling and feeding mechanism of a plastic bag packaging machine includes a rope feeding bracket 2 connected to a packaging machine frame 1 for lifting and lowering, a rope feeding rod 3 being rotatably connected to the rope feeding bracket 2, the rope feeding bracket 2 passing through the rope inlet end of the rope feeding rod 3 and passing through the rope outlet end, a rope feeding plate 4 being provided on the rope outlet end of the rope feeding rod 3, one end of the rope feeding plate 4 being connected to the rope feeding rod 3, and a rope feeding hole 5 being provided on the rope feeding plate 4, a through slot 6 being provided on the rope feeding plate 4, one end of the through slot 6 corresponding to the rope outlet end of the rope feeding rod 3, a rope feeding wheel 7 for changing the feeding direction of the rope bundling, and a driving mechanism being provided between the rope feeding rod 3 and the rope feeding bracket 2, and between the rope feeding bracket 2 and the packaging machine frame 1.

[0025] like Figure 3 and Figure 4 As shown, in this example, preferably, the rope feeding rod 3 is a hollow rod, the tying rope passes through the inside of the rope feeding rod 3, and one end of the through slot 6 corresponds to the hollow rope outlet end on the rope feeding rod 3.

[0026] like Figures 1 to 4 As shown, the rope guide device 14 on one side of the packaging machine frame 1 first conveys the tying rope to the rope inlet end of the rope feeding rod 3, the tying rope passes through the inside of the rope feeding rod 3, and then passes through the rope outlet end, passes around several rope feeding wheels 7, and then changes direction and passes through the rope feeding hole 5, and then enters the strapping machine downward. The strapping process is as follows: the rope feeding bracket 2 rises. At this time, due to the setting of the rope feeding plate 4, the rope feeding hole 5 and the strapping machine below are no longer on the same vertical line. After the rope feeding bracket 2 rises, the tying rope will be in an inclined state. When the plastic bag is moved to the strapping plate 13 , one side of which contacts the inclined lower end of the tying rope, the rope feeding bracket 2 drops again, and the rope feeding rod 3 drives the rope feeding plate 4 to rotate downward at least 90 degrees. The end of the rope feeding plate 4 passes through the tying plate 13 to the bottom, and the inclined tying rope will quickly wrap around the plastic bag at one time. At the same time, the rope feeding hole 5 at the end of the rope feeding plate 4 is close to the tying machine. The tying machine can start tying after receiving the tying rope. The rope feeding bracket 2 rises again, and the rope feeding rod 3 rotates in the opposite direction synchronously, keeping the tying rope tilted again, waiting for the next tying.

[0027] Since the rotation of the rope feeding rod 3 is synchronized with the lifting of the rope feeding bracket 2, the time for conveying the tying rope to be wound around the plastic bag can be reduced, the waiting time for tying the plastic bag can be reduced, and the tying efficiency of the plastic bag can be improved.
