[0027] Example 2: This example provides a shearing mechanism for producing plastic masterbatch. In addition to the technical solutions described in the above examples, it also has the following technical features: the driving component includes: Multiple first gear slots 10 are formed in the mounting plate 2 and connected to multiple sliding grooves 7. A first bevel gear 11 and a second bevel gear 12 are rotatably connected in the first gear slot 10, and the first bevel gear 11 and the second bevel gear 12 mesh with each other. One end of the first bevel gear 11 passes through the inner wall of the first gear slot 10 and extends into the sliding groove 7 and is fixed to one end of the threaded rod 9. Multiple first rotating grooves 13 are formed in the mounting plate 2 and are respectively connected to multiple first gear grooves 10. Multiple first gears 14 are rotatably connected in the multiple first rotating grooves 13, and one end of each of the multiple first gears 14 passes through the inner wall of the multiple first rotating grooves 13 and extends into the multiple first gear grooves 10, and is fixed to multiple second bevel teeth 12 respectively. The second rotating groove 15 is opened in the mounting plate 2 and is connected to a plurality of first rotating grooves 13. A second gear 16 that meshes with a plurality of first gears 14 is rotatably connected in the second rotating groove 15. The second gear groove 17 is formed on the inner wall of the second rotating groove 15 and is connected to the outside. The third bevel gear 18 and the fourth bevel gear 19 are rotatably connected in the second gear groove 17 and mesh with each other.

A rotating rod 20 is fixedly connected to the fourth bevel gear 19, and one end of the rotating rod 20 passes through the inner wall of the second gear groove 17 and extends to the outside and is rotatably connected to the mounting plate 2. A fixing component is located on the periphery of the rotating rod 20 and is used to fix the rotating rod 20.

[0028] In operation, the user manually rotates the lever 20, causing the fourth bevel gear 19 to rotate within the second gear groove 17. This causes the fourth bevel gear 19 to rotate within the second gear groove 17. When the third bevel gear 18 rotates, it drives the second gear 16 to rotate within the second rotation groove 15. The second gear 16 then drives multiple first gears 14 to rotate within multiple first rotation grooves 13. As the multiple first gears 14 rotate, they drive multiple second bevel gears 12 to rotate within multiple first gear grooves 10. These second bevel gears 12 then drive multiple first bevel gears 11 to rotate within multiple first gear grooves 10. When the multiple first bevel gears 11 rotate, one end of each first bevel gear 11 drives multiple threaded rods 9 to rotate within multiple sliding grooves 7, ensuring that the user can drive multiple threaded rods 9 to rotate simultaneously.

A threaded sleeve 22 is threadedly connected to the threaded groove 21.

[0030] In use, the user rotates the threaded sleeve 22 by hand, causing the threaded sleeve 22 to move towards the mounting plate 2 under the action of the threaded groove 21. This makes the threaded sleeve 22 tightly pressed against the mounting plate 2, fixing the rotating rod 20 inside the mounting plate 2 so that it cannot rotate and ensuring that the rotating rod 20 will not be affected by external factors.

[0031] Example 4: This example provides a shearing mechanism for producing plastic masterbatch. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the first bevel gear 11 is rotatably connected to the slide groove 7.

[0032] Specifically, it is ensured that when the first bevel gear 11 rotates, one end of the first bevel gear 11 can rotate normally within the slide groove 7.

[0033] Example 5: This example provides a shearing mechanism for producing plastic masterbatch. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the first gear 14 is rotatably connected to the first gear groove 10.

[0034] Specifically, it is ensured that when the first gear 14 rotates, one end of the first gear 14 can rotate normally within the first gear groove 10.

[0035] Example 6: This example provides a shearing mechanism for producing plastic masterbatch. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the third bevel gear 18 is rotatably connected to the second rotating groove 15.

[0036] Specifically, it is ensured that when the third bevel gear 18 rotates, one end of the third bevel gear 18 can rotate normally within the second rotating groove 15.

[0037] Example 7: This example provides a shearing mechanism for producing plastic masterbatch. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on the multiple threaded rods 9 have the same direction of rotation and the same thread pitch.

[0038] Specifically, when multiple threaded rods 9 rotate, multiple insert rods 8 will be acted upon by the threads of multiple threaded rods 9, and will move the same distance along multiple slides 7 respectively.

[0039] Working principle: In use, the user manually rotates the lever 20, causing the lever 20 to drive the fourth bevel gear 19 to rotate within the second gear slot 17. This causes the fourth bevel gear 19 to drive the third bevel gear 18 to rotate within the second gear slot 17. When the third bevel gear 18 rotates, it drives the second gear 16 to rotate within the second rotation slot 15. The second gear 16 then drives multiple first gears 14 to rotate within multiple first rotation slots 13. When the multiple first gears 14 rotate, they drive multiple second bevel gears 12 to rotate within multiple first gear slots 10. These second bevel gears 12 then drive multiple first bevel gears 11 to rotate within multiple first gear slots 10. When the multiple first bevel gears 11 rotate, their... One end will drive multiple threaded rods 9 to rotate in multiple slide grooves 7, ensuring that the user can drive multiple threaded rods 9 to rotate simultaneously, so that multiple insert rods 8 are acted on by the threads of multiple threaded rods 9 and move along multiple slide grooves 7 respectively, so that multiple insert rods 8 can move closer or further away from each other. When multiple insert rods 8 move closer to each other, one end of multiple insert rods 8 will enter multiple slide grooves 7 from multiple limiting grooves 5 respectively, releasing the fixation of multiple insert blocks 4. At this time, the user can replace multiple cutting blades 6. When multiple insert rods 8 move further away from each other, one end of multiple insert rods 8 will insert into multiple limiting grooves 5 from multiple slide grooves 7 respectively, fixing multiple insert blocks 4 in multiple slots 3 respectively, so that multiple cutting blades 6 can be fixed on one side of the mounting plate 2. When in use, the user rotates the threaded sleeve 22 by hand, so that the threaded sleeve 22 is subjected to the action of the threaded groove 21 and moves towards the mounting plate 2, so that the threaded sleeve 22 is tightly pressed on the mounting plate 2, fixing the rotating rod 20 in the mounting plate 2 and preventing it from rotating, thus ensuring that the rotating rod 20 will not be affected by external factors and will not rotate.
