DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the technical solutions of the present application are specifically described below in combination with the drawings.

[0018] <EMBODIMENT>

[0019] See Figure 1 and Figure 2 This embodiment provides an automated rope cutting device, which includes a cylinder 1, an optical shaft connector 2, a linear bearing 3, a cylinder mounting plate 4, an optical shaft 5, a cylinder connector 6, a moving plate 7, a connecting plate 8, a scissor mounting plate 9, a rope guiding mechanism, pneumatic scissors 11, and a PLC controller.

[0020] The cylinder mounting plate 4 is a fixed component. It forms the frame of the entire device and remains stationary throughout operation. During the actual installation of the automated rope-cutting device, the cylinder mounting plate 4 can be fixed to an existing frame within the factory using conventional methods, depending on production needs. For example, a conveyor belt for transporting cartons to be cut can be installed below the frame; the mounting plate can be fixed to this frame to facilitate automatic rope cutting of the incoming cartons.

[0021] The cylinder 1 is vertically arranged, and the front end cover of the cylinder 1 is installed in the middle position on the upper surface of the cylinder mounting plate 4.

[0022] The movable plate 7 is located below the cylinder mounting plate 4 and is driven by the cylinder 1 to move upward or downward. The movable plate 7 is connected to the piston rod of the cylinder 1 via a cylinder connector 6. The cylinder connector 6 has a cylindrical structure with internal threads on its inner wall and a flange at its bottom. The cylinder connector 6 is fixed to the movable plate 7 by bolts to the flange. The lower end of the piston rod of the cylinder 1 is threaded into the internal threads of the cylinder connector 6.

[0023] There are two linear bearings 3, which are vertically arranged and symmetrically distributed and fixed on the left and right sides of the cylinder mounting plate 4 about the cylinder 1.

[0024] Two optical axes are respectively installed in two linear bearings 3, and the optical axes can move along the axial direction of the linear bearings 3. The lower end of the optical axis 5 is connected and fixed to the movable plate 7. The top end of the optical axis 5 is limited above the linear bearings 3, specifically as follows: the top end of the optical axis 5 is connected and limited above the linear bearings 3 by an optical axis connector 2. The optical axis connector 2 is in the shape of a curved strip, one end of which is fixed to the top end of one of the optical axes 5, and the other end of which is fixed to the top end of the other optical axis 5. The optical axis connector 2 not only prevents the optical axis from slipping out of the linear bearings 3, but also enhances the stability of the optical axis.

[0025] The connecting plate 8 is fixed below the movable plate 7. The automatic scissors are mounted below the connecting plate 8 via the scissor mounting plate 9, with the blade tip pointing downwards. In this embodiment, the automatic scissors are pneumatic scissors 11, which are connected to a PLC controller and controlled by the PLC controller.

[0026] The rope guiding mechanism guides the intersection of two ropes to the blade of the automatic scissors. The rope guiding mechanism includes two support rods 10 and two rope pressing blocks 12. The two support rods 10 are connected below the connecting plate 8, and a rope pressing block 12 is fixed to the lower end of each support rod 10. The rope pressing blocks 12 are wedge-shaped, and the two rope pressing blocks 12 are symmetrically arranged, forming an inverted "V"-shaped gap between them for rope guiding.

[0027] The working process of the automated rope-cutting device in this embodiment is as follows:

[0028] The up-and-down movement of cylinder 4 drives the moving plate 7 to move up and down. With the rope guiding mechanism pointing downwards, a 5-10mm error is allowed between the intersection of the two ropes and the position directly below the scissors. The rope pressing blocks guide the intersection of the two ropes into the inverted "V"-shaped gap formed between the two rope pressing blocks 12, thereby guiding the rope to the blade of the pneumatic scissors 11. The PLC controls the scissors to complete the rope cutting action.

[0029] The automated rope-cutting device in this embodiment has a simple structure, is easy to operate, has a high degree of automation, and improves production efficiency. It can complete one rope-cutting action in about 5 seconds.

[0030] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
