The linear guide rail 32 is vertically arranged and fixed on the moving bracket 23. The linear guide rail 32 has a slider that moves linearly. In this embodiment, the slider of the linear guide rail moves linearly in the vertical direction.

[0042] The electric cutting machine 34 is slidably connected and installed on the linear guide rail 32 through a connecting component, that is, the linear guide rail 32 drives the electric cutting machine 34 to move in the vertical direction, and the linear module 8 drives the electric cutting machine 34 to move in the horizontal direction.

[0043] Refer to Figures 7 to 9 , the connecting component includes: an L-shaped connecting plate 24, a moving connecting plate 30, a guiding bolt 27, an upper spring tray 25, a spring 29, a lower spring tray 26, and an electric cutting machine installation structure.

[0044] The moving connecting plate 30 is slidably connected to the linear guide rail 32 as follows: The moving connecting plate 30 is fixed on the slider of the linear guide rail 32 by bolts, and the linear guide rail drives the moving connecting plate 30 to move up and down.

[0045] The top of the moving connecting plate 30 is provided with a vertical hole. The L-shaped connecting plate 24 has a vertical plate surface and a horizontal plate surface.

[0050] The working principle and working process of the automatic rope cutting device in this embodiment are as follows:

[0051] Working principle: The stroke of the air cylinder 4 is determined by the height of the box to be rope-cut. The air cylinder 4 serves as the active guide of the entire device and drives the moving plate 7 to move upward or downward. The spring in the pressure lever mechanism serves as an auxiliary function, and the tightness of the spring 21 is adjusted by adjusting the positions of the upper adjusting ring 19 and the lower adjusting ring 20.

[0052] Working process: When the piston rod of the air cylinder 4 pushes downward, it drives the moving plate 7 to move downward, and the pressure lever mechanism moves downward until the circular pressing plate presses on the surface of the cardboard box. At this time, the rope on the cardboard box will become loose. Then, the linear module 8 is driven by the motor 37 to move in the horizontal direction, so that the electric cutting machine 34 cuts the intersection of the two binding ropes or straps on the cardboard box. Further, the electric cutting machine 34 can also be finely adjusted in the vertical direction through the linear guide rail 32.

[0053] The automatic rope cutting device in this embodiment has the following advantages: The device has a simple structure and is easy to operate, with a high degree of automation. And compared with the existing manual hand-held electric scissors or electric cutting machines, the production efficiency is greatly improved, and it only takes about 5 seconds to complete a rope cutting action.

[0054] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
