[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a high-efficiency rebar cutting device, comprising a support platform 1 and a fixed column 201. Motors 3 are installed on both the left and right sides of the top of the support platform 1. The output ends of multiple motors 3 are rotatably connected to connecting shafts 5. Gears 4 are fixedly connected to the outer wall of connecting shafts 5. The support platform 1, through the carefully arranged motors 3 on both sides of its top, the efficient and stable connecting shafts 5, and the precisely arranged gears 4, together constitutes an efficient and reliable mechanical system. A connecting shaft 9 is fixedly connected to the front end of the outer wall of gear 4. A connecting plate 11 is fixedly connected to the outer wall of connecting shaft 9. A connecting shaft 12 is fixedly connected to the other end of connecting plate 11. A connecting plate 6 is fixedly connected to the front side of the outer wall of connecting shaft 12. A fixed shaft 13 is fixedly connected to the other end of connecting plate 6. On the front side of the outer wall of the connecting shaft 12, after precision machining and strict quality inspection, there is a cleverly designed connecting plate 6. This connecting plate 6, like a bridge, spans between the connecting shaft 12 and other components, which not only stabilizes the overall structure, but also cleverly realizes the transmission and conversion of force. The left end of the fixed shaft 13 is fixedly connected to the rack 14, and the inner wall of the rack 14 is slidably connected to the slider 10. The other end of the rack 14 is fixedly connected to the fixing plate 8, and the right end of the fixing plate 8 is fixedly connected to the cutter 7. The delicate and precise sliding cooperation between the rack 14 and the slider 10, the rack 14 as the artery of force transmission, its inner wall is carefully polished and as smooth as a mirror. The top left side of the support platform 1 is fixedly connected to the fixing mechanism 2, which is used to fix the object.

[0033] Specifically, the support platform 1, as the supporting foundation of the entire robotic arm, is crucial to its stability. To ensure that there is no shaking during high-speed operation, the output end of the motor 3 is cleverly connected to the connecting shaft 5. Through a precision gear 4 transmission system, the rotational power of the motor 3 is converted into linear or curvilinear motion. Precision-machined gears 4 are fixed on the outer wall of the connecting shaft 5. These gears 4 are not only made of high-quality materials, but also have precise tooth profiles, ensuring smoothness and efficiency in the transmission process. When the motor 3 starts, the gear 4 begins to rotate, driving the connecting shaft 9 connected to it to rotate together. The other end of the connecting plate 11 is fixedly connected to the connecting shaft 12. As the connecting shaft 9 rotates, the connecting shaft 12 also begins to move along a specific trajectory. The slider 10, as the sliding companion of the rack 14, has its inner wall tightly fitted with the tooth groove of the rack 14. When the rack 14 is subjected to a pushing or pulling force from the fixed shaft 13, the slider 2 10 begins to slide on the rack 14. At the right end of the fixed strip 8, a sharp cutter 7 is fixed. The cutter 7 is made of high-strength alloy material and is treated with a special process to ensure that it is not easily worn and remains sharp during high-speed cutting.

[0034] Please see the appendix Figure 4 - Appendix Figure 5 The fixing mechanism 2 includes a fixing column 201, the bottom of which is fixedly connected to the top left side of the support platform 1. A sliding groove 206 is formed inside the fixing column 201. Metal sleeves 202 are fixedly connected to both the upper and lower ends of the inner wall of the fixing column 201. Springs 207 are fixedly connected inside the metal sleeves 202. These springs 207, like elastic spirits hidden in the mechanical heart, play an indispensable role. With their unique elastic restoring force, the springs 207 provide the necessary support for the entire system. The spring 207 has a buffering and shock absorption effect. The other end of the spring 207 is fixedly connected to a metal shaft 208. The other end of the metal shaft 208 is fixedly connected to a slider 203. The right end of the slider 203 is rotatably connected to a rotating shaft 204. The outer wall of the rotating shaft 204 is fixedly connected to a rotating cylinder 205. The top right side of the support platform 1 is fixedly connected to an operating box 20. The rotating shaft 204 is rotatably connected. This connection method not only ensures the efficient transmission of force, but also greatly enhances the stability and durability of the entire structure. The top right side of the support platform 1 is fixedly connected to a handle 19.

[0035] Specifically, inside the fixed column 201, there is a meticulously crafted sliding groove 206. This groove is not only the stage for the slider 203 to slide freely, but also the key to the flexible operation of the entire fixing mechanism 2. In order to ensure the smoothness and accuracy of the slider 203 during the sliding process, the designers cleverly installed metal sleeves 202 at the upper and lower ends of the inner wall of the fixed column 201. One end of the spring 207 is tightly attached to the metal sleeve 202, and the other end is tightly connected to the metal shaft 208, forming a unique buffer mechanism. When the slider 203 moves in the sliding groove 206, the spring 207 can effectively absorb and release energy, ensuring that every movement of the slider 203 is both stable and rapid. The right end of the slider 203 is cleverly connected to the rotating cylinder 205 through the rotating shaft 204. This design not only gives the slider 203 more freedom, but also allows the rotating cylinder 205 to rotate freely with the movement of the slider 203, thereby meeting the fixing requirements in different directions.

[0036] Please see the appendix Figure 1 - Appendix Figure 3 The other end of the connecting shaft 12 is fixedly connected to the connecting plate 16. The inner wall of the left end of the connecting plate 16 is fixedly connected to the rotating shaft 15. The outer wall of the fixing column 201 is fixedly connected to the handle 26. The other end of the connecting shaft 12, after precision machining and strict quality inspection, achieves a seamless connection with the connecting plate 16. This fixed connection is not only a physical tight fit, but also a crystallization of the deep integration of mechanical principles and materials science. The middle of the outer wall of the handle 26 is fixedly connected to the anti-slip sleeve 27. The four corners of the bottom of the support platform 1 are all fixedly connected to the support column 28. The other ends of the multiple support columns 28 are fixedly connected to the base. 24. A fixing plate 21 is fixedly connected to the top center of the support platform 1. Support columns 22 are fixedly connected to the top left and right sides of the fixing plate 21. A baffle 17 is fixedly connected to the top right side of the support platform 1. The other end of the support column 28 is firmly fixedly connected to the base 24 by high-strength bolts or welding. This connection method not only ensures the seamless connection between the support column and the base 24, but also greatly enhances the overall rigidity and load-bearing capacity of the structure. An outlet box 18 is fixedly connected to the inner wall of the support platform 1. A baffle 23 is fixedly connected to the top left side of the support platform 1. Protective sleeves 25 are fixedly connected to the four corners of the outer wall of the support platform 1.

[0037] Specifically, the design of the connecting plate 3 16 is ingenious. The rotating shaft 2 15 is cleverly embedded and fixed in the inner wall of its left end. This design ensures the stability and flexibility of the machine during operation. Secondly, the outer wall of the handle 2 26 is also carefully equipped with an anti-slip sleeve 27. This is not only for aesthetics, but also to prevent hand slippage during use and ensure the safety and stability of operation. Looking at the main structure of the support platform 1, the four corners of its bottom are all firmly connected to the support column 2 28. The other end of the multiple support columns 2 28 jointly supports the base 24. The wide design of the base 24 not only increases the stability of the machine, but also makes it more stable on the ground. In addition, the inner wall of the support platform 1 is also fixedly connected to an outlet box 18. This design cleverly solves the problem of material or product output, making the entire workflow smoother. On the top left side of the support platform 1, the baffle 2 23 is also fixedly connected. The model of the servo motor (3) is ZWMD012012, and the model of the operation box (20) is ZKC2410KA.

[0038] Working principle: The device feeds the reinforcing bar into the rotating drum 205 and then conveys it forward. The motor 3 drives the gear 4 to rotate. A connecting plate 21 is fixedly connected to the outer wall of the motor 3. The connecting plate 21 drives the connecting plate 16 to slide. A rack 14 is fixedly connected to the front end of the connecting plate 16. The rack 14 meshes with the gear 4. The rack 14 has a groove inside and a slider 20 is slidably connected to it, thereby moving and limiting the device. The device realizes the functions of automatic cutting and automatic control, which greatly improves the cutting efficiency and the level of production automation.

[0039] The device uses a rotating drum 205 to roll and fix a steel bar. Fixed columns 201 are fixed at both ends of the rotating drum 205. The inner wall of the fixed column 201 is provided with a sliding groove 206 that slides and engages with the slider 203. An elastic device metal shaft 208 is fixedly connected to the outer wall of the slider 203. This allows the rotating drum 205 to accommodate more materials while also using the elastic device to firmly fix the materials.
