Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a shearing mechanism for modified plastics, including a shearing table 1 and a shearing frame 2. The shearing frame 2 is located at the top of the shearing table 1 and is fixedly connected thereto. A hydraulic rod 3 is fixedly installed inside the shearing frame 2. An installation box 4 is slidably connected inside the shearing frame 2. The installation box 4 is fixedly connected to the output end of the hydraulic rod 3. Cross-shaped sliding grooves 6 are opened on both sides of the inner wall of the shearing frame 2. A cross-shaped slider 7 is slidably connected inside the cross-shaped sliding groove 6. The cross-shaped slider 7 is fixedly connected to the installation box 4. One side of one of the cross-shaped sliders 7 is fixedly connected to a first motor 5. A first bidirectional threaded rod 11 is rotatably connected inside the installation box 4. One side of the first bidirectional threaded rod 11 is fixedly connected to the output end of the first motor 5. Two first sliders 12 are threadedly connected to the outer side of the first bidirectional threaded rod 11. The bottoms of the two first sliders 12 are both fixedly connected to mounting blocks 13. A shearing blade 14 is clamped inside the mounting block 13. A placement opening 8 is opened on one side of the shearing frame 2. By driving the first bidirectional threaded rod 11 to operate through the first motor 5, while the first bidirectional threaded rod 11 is operating, the two first sliders 12 on its outer side approach or move away from each other, and thus the distance between the two mounting blocks 13 can be correspondingly adjusted, thereby adjusting the shearing length of the modified plastics, enabling it to adapt to different specifications of shearing requirements. And during the adjustment, through the cooperation of a first connecting plate 17, a second connecting plate 18 and a connecting groove 25, the I-shaped slider 23 can move accordingly, making the shearing groove 24 and the shearing blade 14 keep in a vertical state, ensuring that the shearing work can be completed at one time, and thus improving the work efficiency.

[0023] A T-shaped connecting block 15 is fixedly connected to the top of the shearing blade 14. A sliding groove matching the T-shaped connecting block 15 is opened inside the mounting block 13. The sliding groove is slidably connected to the T-shaped connecting block 15. A U-shaped connecting plate 16 is clamped on one side of the mounting block 13. The U-shaped connecting plate 16 is clamped with the T-shaped connecting block 15. Through the cooperation of the provided U-shaped connecting plate 16 and the T-shaped connecting block 15, the shearing blade 14 can be replaced. A first connecting plate 17 is fixedly installed inside the mounting block 13. A second connecting plate 18 is slidably connected inside the first connecting plate 17. A limiting block 19 is clamped on one side of the mounting block 13. Both the first connecting plate 17 and the second connecting plate 18 are clamped with the limiting block 19. Through the cooperation of the provided second connecting plate 18 and the limiting block 19, the first connecting plate 17 can be extended, driving the I-shaped slider 23 to move. An I-shaped sliding groove 22 is opened inside the shearing table 1. An I-shaped slider 23 is slidably connected inside the I-shaped sliding groove 22. A shearing groove 24 and a connecting groove 25 are opened on the top of the I-shaped slider 23. The connecting groove 25 cooperates with the second connecting plate 18, and the shearing groove 24 cooperates with the shearing blade 14. Through the cooperation of the provided connecting groove 25 and the second connecting plate 18, the I-shaped slider 23 can move along with the mounting block 13, and through the cooperation of the provided shearing groove 24 and the shearing blade 14, it is ensured that the shearing can be completed at one time.

[0024] One end of the shearing frame 2 is fixedly installed with a second motor 9. One side of the inner wall of the shearing frame 2 is rotatably connected with a second bidirectional threaded rod 20. The second bidirectional threaded rod 20 is fixedly connected to the output end of the second motor 9. Two second sliders 21 are threadedly connected to the outer side of the second bidirectional threaded rod 20. One end of each of the two second sliders 21 is fixedly connected with a limiting plate 10. By arranging the limiting plate 10, the modified plastic can be limited, thereby ensuring the shearing effect. The height of the I-shaped slider 23 is flush with the shearing table 1. By setting it in a flush state, the modified plastic can be smoothly placed under the shearing blade 14.

[0025] In summary, for the shearing mechanism of the modified plastic, during use, the length to be sheared is determined. Subsequently, the distance between the two shearing blades 14 is adjusted. When adjusting, the first motor 5 drives the first bidirectional threaded rod 11 to rotate. While the first bidirectional threaded rod 11 rotates, the two first sliders 12 on its outer side approach or move away from each other, thereby correspondingly adjusting the distance between the two mounting blocks 13, and thus adjusting the shearing length of the modified plastic to adapt to different shearing requirements of different specifications. And when adjusting, through the cooperation of the first connecting plate 17, the second connecting plate 18 and the connecting groove 25, the I-shaped slider 23 can move accordingly, so that the shearing groove 24 and the shearing blade 14 are kept in a vertical state, ensuring that the shearing work can be completed at one time, thereby improving the work efficiency. After the adjustment is completed, the second connecting plate 18 is retracted. Subsequently, the modified plastic to be sheared is placed above the shearing table 1 through the placing opening 8. And by driving the second bidirectional threaded rod 20 to rotate through the arranged second motor 9, the two second sliders 21 can approach or move away from each other, thereby driving the limiting plate 10 to move accordingly to limit and fix the modified plastic. Subsequently, the hydraulic rod 3 is started, and the hydraulic rod 3 drives the mounting box 4 to move downward and drives the shearing blade 14 to move downward to shear the modified plastic.
