A belt 34 is wound between the first pulley 33 and the second pulley 35. The roller 310 can contact the side wall of the chute 2 so that when the roller 310 rotates, the trolley 3 can move along the chute 2. When the first motor 32 operates, the output end of the first motor 32 can drive the first pulley 33 to rotate. The first pulley 33 can drive the second pulley 35 to rotate. And the second pulley 35 is fixedly connected to the roller 310. Therefore, at this time, the roller 310 can rotate so that the trolley 3 can slide in the chute 2.

[0042] A fixing block 36 is fixedly connected to the outside of the first outer shell 31. A first pressing plate 37 is installed on the fixing block 36. The end of the cable tie 6 can be pressed between the first pressing plate 37 and the fixing block 36. Thus, when the trolley 3 slides along the chute 2, the cable tie 6 can be wound around the box to be bandaged for one week. A first rotating shaft 38 is fixedly connected to the first pressing plate 37. The first rotating shaft 38 is inserted into the fixing block 36 and the first rotating shaft 38 can rotate in the fixing block 36. A first torsion spring is sleeved outside the first rotating shaft 38. A handle 39 with one end upturned is fixedly connected to the first pressing plate 37. When the handle 39 is pressed, the first pressing plate 37 can be separated from the fixing block 36, so that the cable tie 6 is separated from the trolley 3.

[0043] Regarding the second outer shell 41: The pushing mechanism 4 includes a second outer shell 41. An upper clamping block 411 is fixedly connected to the second outer shell 41.

[0049] Both ends of the driving rotating shaft 56 are fixedly connected with third gears 59, the lower surface of the lower pressing plate 43 is provided with tooth patterns, and when the second housing 41 slides into the gantry frame 1, the lower surface of the lower pressing plate 43 can contact the third gears 59 to make the driving rotating shaft 56 rotate. The lower pressing plate 43 has a downward-sloping ramp so that when the lower pressing plate 43 contacts the third gears 59, the lower pressing plate 43 can drive the upper pressing plate 42 located above to tilt upward and clamp the cable tie 6 between the two upper pressing plates 42.

[0050] A spring 510 is sleeved outside the cutter 55, the lower end of the spring 510 is installed on a pressing block 511, and when the cutter 55 moves downward, the pressing block 511 can press on the cable tie 6. A knife groove is provided on the lower wall of the through hole 54, and when the cutter 55 moves downward, the lower end of the cutter 55 can enter the knife groove.

[0051] For the treatment of the knotting part:

[0052] The driving mechanism 4 further includes a third housing 47. A third motor 48 is fixedly connected inside the third housing 47. A second gear 49 is fixedly connected to the output end of the third motor 48. That is, when the third motor 48 operates, the second gear 49 can cooperate with the second rack 72, so that the third housing 47 pushes the second housing 41 to slide.

[0053] The track 7 includes a guide rail 71. A second rack 72 is arranged on the guide rail 71. The second gear 49 meshes with the second rack 72, so that when the second gear 49 rotates, the third housing 47 can move along the guide rail 71.

[0054] A second motor 45 is fixedly connected inside the second housing 41. A first gear 46 is fixedly connected to the output end of the second motor 45. A fourth gear 73 is fixedly connected to the guide rail 71 and can mesh with each other, so that the second housing 41 can rotate around the guide rail 71. The purpose of this structural design is to enable the second housing 41 to rotate. When both ends of the cable tie 6 are clamped by the second housing 41, the second housing 41 rotates, thereby tightening the cable tie 6.

[0055] An electric push rod 74 is arranged inside the guide rail 71, and a soldering iron 75 is arranged at the end of the electric push rod 74. When the electric push rod 74 extends, the soldering iron 75 can abut against the surface of the material. After the cable tie 6 is tightened, the soldering iron 75 can extend out. By setting an appropriate temperature, the soldering iron 75 can fuse the wound cable ties 6 together to prevent the cable ties 6 from separating. Then the second housing 41 can return to its original position.
