[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] An adjustable sling shredding mechanism includes a base 4, a fixed seat 7 is fixedly connected to one upper end of the base 4, a fixed plate 2 is fixedly connected to the upper side of the fixed seat 7, the fixed plate 2 is rotatably connected to the central shaft of the rotating disk 12, a drive assembly is connected to the end of the central shaft of the rotating disk 12, and a cutting assembly 3 is connected to the rotating disk 12. The base 4 is also connected to a tensioning assembly, which includes a fixing block 5, a connecting block 8, and an auxiliary roller 6. The fixing block 5 and the connecting block 8 are fixedly connected to the base 4. One end of the auxiliary roller 6 is rotatably connected to the fixing block 5, and the other end of the auxiliary roller 6 is rotatably connected to the connecting block 8.

[0015] In this embodiment, the sling passes around the auxiliary roller 6, which can rotate, thereby tensioning and guiding the sling.

[0016] In this embodiment, the fixed plate 2 is rotatably connected to the central axis of the rotating disk 12, enabling the rotating disk 12 to rotate around the central axis. The drive assembly is connected to the end of the central axis of the rotating disk 12, providing power for the rotation of the rotating disk 12. The cutting assembly 3 is connected to the rotating disk 12. When the rotating disk 12 rotates, it drives the cutting assembly 3 to rotate together, thereby realizing the cutting of the sling. The base 4 is also connected to a tensioning assembly for tensioning the sling, ensuring that the sling maintains a certain tension during the cutting process and improving the cutting quality.

[0017] The cutting assembly 3 includes a mounting plate 301, a second mounting hole 302 formed on the mounting plate 301, a mounting sleeve 303, a cutter 304, and a rotating rod limiting hole 305. One end of the mounting sleeve 303 is fixed to the mounting plate 301. The mounting plate 301 and the mounting sleeve 303 are provided with a rotating rod limiting hole 305, which is cross-shaped. A plurality of evenly arranged cutters 304 are fixed on the mounting sleeve 303. A plurality of evenly arranged second limiting holes are formed on the mounting plate 301. The mounting plate 301 is connected to the rotating plate 12.

[0018] In this embodiment, the mounting plate 301 is fixed on the rotating plate 12 and rotates together with the rotating plate 12. The second mounting hole 302 is used to connect the mounting plate 301 and the rotating plate 12. One end of the mounting sleeve 303 is fixed on the mounting plate 301. The cutter 304 is fixed on the mounting sleeve 303 and rotates together with the mounting sleeve 303. The rotating rod limiting hole 305 is cross-shaped and is used to limit the position of the rotating rod 13 to ensure accurate installation and positioning of the cutter 304. Several cutters 304 are evenly arranged on the mounting sleeve 303. When the rotating plate 12 rotates, the cutter 304 cuts the sling. The second limiting hole is used to further fix the relative position of the mounting plate 301 and the rotating plate 12.

[0019] The other end of the rotating disk 12 is a circular plate and has a set of evenly arranged first mounting holes 121. The number of the first mounting holes 121 and the second mounting holes 302 are equal and can correspond one-to-one. The rotating disk 12 and the mounting disk 301 can be locked together by bolts and nuts. The bolts can pass through the corresponding first mounting holes 121 and second mounting holes 302.

[0020] In this embodiment, the rotating disk 12 and the mounting disk 301 are fixedly connected by bolts passing through the first mounting hole 121 and the second mounting hole 302, and then locked with nuts. This connection method facilitates installation and disassembly, and makes it convenient to maintain and replace the cutting assembly 3.

[0021] The drive assembly includes a motor 9, a belt 10, a first pulley 1 and a second pulley 11. The first pulley 1 is fixedly connected to the end of the central shaft of the rotating disk 12. The first pulley 1 is connected to the second pulley 11 via the belt 10. The second pulley 11 is fixedly connected to the output shaft of the motor 9. The motor 9 is fixedly connected to the connecting block 8.

[0022] In this embodiment, the motor 9 serves as the driving source, and the output shaft rotates to drive the second rotating wheel 11 to rotate. The second rotating wheel 11 is connected to the first rotating wheel 1 via the belt 10. The first rotating wheel 1 is fixed at the end of the central shaft of the rotating disk 12, thereby driving the central shaft of the rotating disk 12 to rotate, causing the rotating disk 12 to rotate.

[0023] The spacing between the cutters 304 is the same.

[0024] In this embodiment, the spacing between the cutters 304 is the same, the spacing between each adjacent cutter 304 is the same, and the spacing between the cutters 304 can be changed according to the number of cutters 304, so as to cut suspenders of different widths.

[0025] The working process of this utility model is as follows: Select the appropriate mounting sleeve 303 with the appropriate blade spacing for the cutter 304 and install it on the rotating disk 12. Pass the sling to be cut through the auxiliary roller 6 of the tensioning assembly to create tension between the sling and the cutter 304. Connect one end of the raw material to be cut to the input end and the other end to the pull output end (this is existing technology in the field and will not be described in detail or shown in the figure). During the movement of the raw material, start the motor 9. The output shaft of the motor 9 drives the second rotating wheel 11 to rotate. Through the belt 10, the first rotating wheel 1 drives the rotating disk 12 to rotate, which in turn drives the cutting assembly 3 to rotate. The rotating cutter 304 cuts the sling. Check the wear of the cutter 304 regularly. When the cutter 304 is worn or damaged, remove the bolts and nuts, remove the mounting disk 301, and replace the cutter 304.

[0026] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
