Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Specifically, the workbench 1 supports and fixes the support frame 2. The upright plate 3, fixed inside the support frame 2, supports and fixes the first cylinder 4. The first cylinder 4 can push the push block 5 to slide. The push block 5 supports the first rotating shaft 6 and can drive the first rotating shaft 6 to slide synchronously. The rotating rod 7 supports and fixes the first rotating shaft 6 and can rotate through the sliding of the first rotating shaft 6. The other end of the rotating rod 7 also supports and fixes the second rotating shaft 8. The slider 9 supports the second rotating shaft 8 and can slide through the rotation of the second rotating shaft 8. The limiting strip 10 is fixed to the inner bottom wall of the support frame 2 and supports and limits the sliding of the slider 9 to prevent deviation during the sliding process. The slider 9 fixes the connecting plate 11 and can drive the connecting plate 11 to slide against the inner wall of the workbench 1. The connecting plate 11 fixes the anti-deviation plate 12, thereby driving the anti-deviation plates 12 on both sides to slide synchronously. This can limit the movement of SMC materials of different sizes and prevent deviation during the cutting process.

[0019] Reference Figure 1 and Figure 3 The material pulling assembly includes a support plate 13, a second cylinder 14 is fixedly connected inside the support plate 13, a push plate 15 is fixedly connected to the output end of the second cylinder 14, the outer wall of the push plate 15 is slidably connected to the inner wall of the worktable 1, a support platform 16 is fixedly connected to the upper surface of the push plate 15, the lower surface of the support platform 16 is slidably connected to the upper surface of the worktable 1, a limit plate 17 is slidably connected inside the support platform 16, and the lower surface of the limit plate 17 is fixedly connected to the upper surface of the worktable 1. Specifically, the support plate 13 is fixed to the lower surface of the worktable 1 to fix the second cylinder 14. Activating the second cylinder 14 can push the push plate 15 to slide against the inner wall of the worktable 1. The push plate 15 fixes the support platform 16, allowing the support platform 16 to slide. The support platform 16 supports the SMC material. When it slides, it will drive the SMC material to slide synchronously. The material pulling process facilitates subsequent cutting. The limiting plate 17 is fixed to the upper surface of the worktable 1 to support and limit the support platform 16, preventing deviation during the sliding process.

[0020] Reference Figure 1 and Figure 4A base 29 is fixedly connected to the lower surface of the workbench 1, and a fixed plate 18 is fixedly connected to the upper surface of the workbench 1. A limit groove 19 is formed inside the fixed plate 18. A motor 20 is fixedly connected to the outer wall of the fixed plate 18. A transmission rod 21 is fixedly installed at the output end of the motor 20. The outer wall of the transmission rod 21 is rotatably connected to the inside of the fixed plate 18. An eccentric wheel 22 is fixedly connected to the outer wall of the transmission rod 21. A connecting block 23 is fixedly connected to the bottom of the eccentric wheel 22. A connecting shaft 24 is fixedly connected inside the connecting block 23. A connecting seat 25 is rotatably connected to the outer wall of the connecting shaft 24. A connecting plate 26 is fixedly connected to the lower surface of the connecting seat 25. A limit block 27 is fixedly connected to the outer wall of the connecting plate 26. The outer wall of the limit block 27 is slidably connected to the inner wall of the limit groove 19. A cutting blade 28 is fixedly connected to the lower surface of the connecting plate 26. The cutting blade 28 is located directly above the support table 16. Specifically, the base 29, fixed to the upper surface of the worktable 1, provides stable support for the worktable 1. The fixing plate 18, also fixed to the upper surface of the worktable 1, supports and fixes the motor 20. When the motor 20 is started, its driving action causes the transmission rod 21 to rotate stably inside the fixing plate 18. The transmission rod 21 fixes the eccentric wheel 22 and drives it to rotate synchronously. Because the eccentric wheel 22 and transmission rod 21 are eccentrically designed, with the transmission rod 21 not centered on the eccentric wheel 22, the rotation of the transmission rod 21 causes the eccentric wheel 22 to swing. The eccentric wheel 22 then... The connecting block 23 serves to fix the connecting shaft 24, allowing the connecting block 23 and the connecting shaft 24 to shake synchronously and create a height difference. The connecting seat 25 supports the connecting shaft 24 and fixes the connecting plate 26. The connecting plate 26 fixes the limiting block 27, which is located on the inner wall of the limiting groove 19. Therefore, the limiting action of the limiting block 27 allows the connecting plate 26 to slide vertically up and down. The connecting plate 26 supports and fixes the cutting blade 28, thereby driving the cutting blade 28 to slide up and down continuously to cut the SMC material.

[0021] Working principle: When the equipment is needed, the distance between the anti-deviation plates 12 is adjusted according to the size of different SMC materials. The first cylinder 4 is activated to push the push block 5 to slide. When the push block 5 slides, it will push the rotating rod 7 to rotate through the first rotating shaft 6 inside. During the rotation of the rotating rod 7, it will pull the slider 9 to slide through the second rotating shaft 8. When the sliders 9 on both sides slide, they will drive the connecting plate 11 to slide on the inner wall of the worktable 1. At the same time, the connecting plate 11 will also drive the anti-deviation plates 12 to slide, thereby adjusting the distance between the anti-deviation plates 12. This achieves flexible adjustment of the spacing between the anti-deviation plates 12 to meet the cutting needs of SMC materials of different sizes, and limits their movement in the process to prevent deviation during the cutting process. When SMC material needs to be cut, the portion of SMC material to be cut is placed on the upper surface of the support platform 16. The motor 20 is started, driving the transmission rod 21 to rotate. When the transmission rod 21 rotates, it drives the eccentric wheel 22 to rotate. During the rotation of the eccentric wheel 22, the connecting block 23 and the connecting shaft 24 rotate. The connecting shaft 24 drives the connecting plate 26 to slide through the connecting seat 25. When the connecting plate 26 slides, it drives the limiting block 27 to slide against the inner wall of the limiting groove 19. When the connecting plate 26 slides, it simultaneously drives the cutting blade 28 to slide up and down, thereby completing the cutting of the SMC material and achieving automatic cutting in a short time. The equipment achieves precise cutting and continuous production, ensuring that the cut edges of SMC materials are neat and the dimensions are consistent. After cutting, the second cylinder 14 is activated to push the push plate 15 to slide. When the push plate 15 slides, it will drive the support table 16 to slide, thereby realizing the material pulling process of SMC materials. This equipment can not only flexibly adjust the spacing of the anti-deviation plates 12 to meet the cutting needs of SMC materials of different sizes, but also limit them in the process to prevent deviation during cutting. It can also complete automatic cutting in a short time, achieving precise cutting and continuous production, ensuring that the cut edges of SMC materials are neat and the dimensions are consistent.
