[0054] Example 8

[0055] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 It is understood that the belt feeding device of the present invention also includes a swing assembly 6 and a belt bending assembly 8. The swing assembly 6 is fixed on the upper panel of the frame 1, and the belt bending assembly 8 is located on the right side of the frame 1. The swing assembly 6 and the belt bending assembly 8 are connected and located between the buckle feeding assembly 7 and the main guide assembly. The swing assembly 6 includes a base 61, a cylinder II 62, and a rotating shaft 63. The base 61 is fixed on the upper panel of the frame 1, the cylinder II 62 is mounted on the base 61, and the rotating shaft 63 mates with the hole of the protrusion on the right side of the base 61. The belt bending assembly 8 includes a frame assembly 81, a rack assembly 82, a bending assembly 83, and a cylinder III 84.

[0060] like Figure 12 , Figure 13 As shown, the working principle of the tape feeding device of the present invention is as follows: Cylinder I 31 extends and pushes the tape feeding assembly 4 to swing through the connecting plate 20, so that the tape feeding wheel 42 and the driven wheel 51 come into contact. Then, cylinder II 62 extends and pushes the tape bending assembly 8 to swing in. After that, the operator inserts the steel tape into the buckle 77 along the gap between the main guide assembly and the buckle feeding assembly 7 and feeds it between the tape feeding wheel 42 and the driven wheel 51. At this time, the tape feeding motor 41 rotates to start feeding the tape. After feeding the tape for one revolution, the operator inserts the steel tape into the buckle 77 again and feeds it to the tape bending assembly 8. Then, cylinder III 84 works, driving the bending assembly 83 to work through the rack assembly 82, thereby realizing the bending of the head of the packing steel tape. Finally, cylinder I 31 resets, the connecting plate 20 drives the tape feeding assembly 4 to retract, cylinder II 62 resets, the tape bending assembly 8 swings out, and the operator pulls the bent steel tape out from the buckle feeding assembly 7 for the subsequent bundling process.
