[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 In this embodiment of the present invention, the double-knife assembly for the ribbon binding machine includes a ribbon binding machine body 1 and a first knife swing frame 3 movably disposed inside the ribbon binding machine body 1. A second knife swing frame 7 is disposed inside the first knife swing frame 3 and swings in a staggered manner. A support frame 6 is synchronously connected to one side of both the first knife swing frame 3 and the second knife swing frame 7. The support frames 6 are both vertically located inside the ribbon binding machine body 1. The first knife swing frame 3 and the second knife swing frame 7 are respectively provided with a first support connecting seat 13 and a second support connecting seat 14 that movably cooperate with the support frames 6. The first support connecting seat 13 is horizontally located on the left and right sides of the first knife swing frame 3, and the second support connecting seat 14 is horizontally located on the left and right sides of the second knife swing frame 7. Thus, when the first knife swing frame 3 and the second knife swing frame 7 swing up and down inside the ribbon binding machine body 1, they synchronously drive the support frames 6 to perform double-set up and down staggered lifting and lowering inside the ribbon binding machine body 1, thereby performing up and down staggered traction on the ribbon.

[0018] A knife-handling shaft 15 is provided between the first knife-handling frame 3 and the main body 1 of the webbing binding machine. The knife-handling shaft 15 passes through the first knife-handling frame 3 and the second knife-handling frame 7 and is mounted horizontally on the main body 1 of the webbing binding machine. The knife-handling shaft 15 and the first knife-handling frame 3 are coaxially driven, so that when the knife-handling shaft 15 rotates inside the main body 1 of the webbing binding machine, it drives the first knife-handling frame 3 to swing. At the same time, the first knife-handling frame 3 swings and moves up and down inside the main body 1 of the webbing binding machine along with the bracket frame 6 movably connected to it.

[0019] A knife-handling frame transmission shaft 4 is provided between the knife-handling shaft 15 and the main body 1 of the webbing binding machine, and the knife-handling frame transmission shaft 4 is coaxially connected to the knife-handling shaft 15. The knife-handling frame transmission shaft 4 is horizontally mounted inside the webbing binding machine main body 1. The webbing binding machine main body 1 is provided with a servo motor 8 that is in transmission cooperation with the knife-handling frame transmission shaft 4, and a transmission gear 9 is provided between the servo motor 8 and the knife-handling frame transmission shaft 4. The transmission gear 9 and the knife-handling frame transmission shaft 4 are coaxially driven, and the servo motor 8 and the transmission gear 9 are in driving cooperation. Thus, when the servo motor 8 drives the transmission gear 9 to rotate, it drives the knife-handling frame transmission shaft 4 to drive the knife-handling shaft 15 to rotate inside the webbing binding machine main body 1.

[0020] A support beam 2 is provided between the second blade swing frame 7 and the main body 1 of the webbing binding machine. The support beam 2 is located laterally inside the main body 1 of the webbing binding machine. The top of the support beam 2 is provided with a connecting rod transmission seat 10 for driving the second blade swing frame 7. The connecting rod transmission seat 10 is connected to the second blade swing frame 7 and drives the second blade swing frame 7 to swing up and down inside the first blade swing frame 3 with the blade shaft 15 as the swing center. When the second blade swing frame 7 swings, the bracket frame 6 connected to it moves up and down inside the main body 1 of the webbing binding machine.

[0021] A connecting rod 11 is provided between the connecting rod transmission seat 10 and the second gate knife swing frame 7. The connecting rod 11 is vertically located on the outer side of the connecting rod transmission seat 10. The connecting rod 11 is movably connected to the connecting rod transmission seat 10, and the other end of the connecting rod 11 is movably connected to the second gate knife swing frame 7. When the motor drives the connecting rod transmission seat 10 to run, the connecting rod transmission seat 10 drives the connecting rod 11 to move up and down on its side and causes the second gate knife swing frame 7 to swing up and down inside the first gate knife swing frame 3.

[0022] A frame guide 5 is provided between the bracket frame 6 and the main body 1 of the webbing binding machine. The frame guide 5 is located obliquely at the top of the main body 1 of the webbing binding machine, and the bracket frame 6 is vertically slidably disposed inside the frame guide 5. Thus, the frame guide 5 can guide the bracket frame 6 to move up and down inside the main body 1 of the webbing binding machine.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
