Abstract
Description
Technical Field
[0001] This utility model relates to the field of expansion and contraction inner baffle plate technology, and in particular to an integrated feeding expansion and contraction inner baffle plate. Background Technology
[0002] The feeding expansion and contraction inner baffle plate is usually a device used in automated production lines or mechanical equipment to handle coiled materials such as metal strips. Its main function is to help stabilize and guide the material, ensuring that the material can smoothly enter the processing equipment, while avoiding problems such as material deviation, wrinkling or breakage.
[0003] The common feeding expansion and contraction inner baffle plate consists of four iron strips welded to the inner baffle retaining ring. Due to the small contact area at the weld, when the machine is running, especially during the feeding process (i.e., the rapid unfolding of the coil), the iron strips will be subjected to large tensile and shear forces. These forces may cause cracks in the weld, or even complete weld failure. Once the weld cracks, the iron strip may detach from the inner baffle retaining ring and be thrown out at high speed. This situation can not only cause equipment damage, but also pose a threat to on-site operators and even cause workplace injuries. Even if no serious flying incident occurs, the gradual wear of the weld points will lead to frequent inspections and maintenance, increasing equipment maintenance costs and potentially causing unplanned shutdowns of the production line, affecting production efficiency.
[0004] Therefore, to address the safety hazard posed by the aforementioned feeding expansion and contraction inner baffle plate, which is prone to weld breakage and flying of iron strips during material feeding, an integrated feeding expansion and contraction inner baffle plate can be designed. The four iron strip bodies are interconnected as a whole through grooves, slide bars, and limiting plates, and then welded to the expansion and contraction retaining ring. During the feeding process, when the iron strip body is subjected to external force, this force can be effectively distributed to the other three iron strip bodies, effectively preventing the iron strips from breaking welds and flying out during feeding, thus reducing safety hazards and solving the aforementioned problem. Utility Model Content
[0005] To overcome the common problem of expansion and contraction of the inner baffle plate during feeding, which easily leads to weld breakage and the iron strip flying out during feeding, posing a safety hazard.
[0006] The technical solution of this utility model is as follows: an integrated feeding expansion and contraction inner baffle plate, including a base plate; it also includes an expansion and contraction assembly, expansion and contraction retaining rings, iron strip bodies, sliding grooves, sliding bars, and limiting plates. A height adjustment assembly is provided at the upper end of the base plate, and a worktable is connected to the upper end of the height adjustment assembly. A support plate is welded to the upper surface of the worktable, and a bearing seat is installed at the upper end of the support plate. A rotating shaft is installed inside the bearing seat, and a feeding tray is fixedly connected to one end of the rotating shaft. An expansion and contraction assembly is installed on the surface of the feeding tray, and four expansion and contraction retaining rings are connected to the expansion and contraction assembly. An iron strip body is welded to the surface of each of the four expansion and contraction retaining rings. Four sliding grooves are opened on the surface of the iron strip body, and a sliding bar is slidably connected inside each of the four sliding grooves. The two ends of the sliding bar are slidably connected to two iron strip bodies respectively, and a limiting plate is welded to each end of the sliding bar.
[0007] Preferably, the four iron strip bodies are interconnected into a single unit via grooves, slide bars, and limiting plates, and then welded together onto the expansion and contraction retaining ring. During the feeding process, when the iron strip bodies are subjected to external forces, because they are interconnected as a whole via grooves, slide bars, and limiting plates, these forces can be effectively distributed to the other three iron strip bodies. This not only reduces the burden on individual welding points but also reduces the risk of weld breakage due to local stress concentration, greatly enhancing welding strength and effectively preventing weld breakage due to insufficient contact area during feeding. Because the iron strip bodies form a more robust integrated structure, even if a small crack or loosening occurs in a certain part, the entire structure can still remain intact, greatly reducing the possibility of the iron strips flying off due to weld breakage. This mechanism not only enhances the connection strength between various components but also improves the rigidity and stability of the entire structure, enabling the equipment to operate safely at higher speeds and under greater loads.
[0008] Preferably, the height adjustment assembly includes an electric push rod and a telescopic rod, with the electric push rod mounted on the upper end of the base plate and the output end of the electric push rod connected to a worktable.
[0009] Preferably, four telescopic rods are installed on the upper end of the base plate, and the upper ends of the four telescopic rods are connected to a worktable.
[0010] Preferably, a support block is welded to the upper surface of the worktable, and the other end of the rotating shaft is rotatably connected to the support block through a bearing.
[0011] Preferably, the expansion and contraction assembly includes a motor, a lead screw, a moving block, a connecting block, a first steering component, a connecting rod, and a second steering component. The motor is mounted on the surface of the loading tray, and the output end of the motor is connected to the lead screw. Two moving blocks are threadedly connected to the surface of the lead screw.
[0012] Preferably, four connecting blocks are welded to the surface of the movable block. A steering component one is installed at the end of the connecting block away from the movable block. The movable block is rotatably connected to one end of a connecting rod through the steering component one. A steering component two is installed at the other end of the connecting rod. An expansion and contraction retaining ring is welded to the surface of the two steering components two.
[0013] Preferably, a fixed frame is welded to the surface of the loading tray, the connecting block is slidably connected to the fixed frame, and four fixed plates are welded to the surface of the loading tray, each of the four fixed plates being rotatably connected to the two connecting rods.
[0014] The beneficial effects of this utility model are:
[0015] 1. The four iron strip bodies are connected to each other as a whole through grooves, slide bars and limiting plates, and then welded to the expansion and contraction retaining ring. When the iron strip body is subjected to external force during the feeding process, the force can be effectively distributed to the other three iron strip bodies, reducing the burden on individual welding points and reducing the risk of weld failure due to local stress concentration. Because the iron strip bodies form a more robust whole structure, even if a small crack or loosening occurs in a certain part, the entire structure can still remain intact, greatly reducing the possibility of the iron strip flying off due to weld failure. This mechanism not only enhances the connection strength between various components, but also improves the rigidity and stability of the entire structure, enabling the equipment to operate safely at higher speeds and under greater loads.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 This utility model provides an embodiment of an integrated feeding expansion and contraction inner baffle, including a base plate 1; it also includes an expansion and contraction assembly, expansion and contraction retaining rings 17, iron strip bodies 20, sliding grooves 21, sliding bars 22, and limiting plates 23. A height adjustment assembly is provided at the upper end of the base plate 1, and a worktable 4 is connected to the upper end of the height adjustment assembly. A support plate 5 is welded to the upper surface of the worktable 4, and a bearing seat 6 is installed at the upper end of the support plate 5. A rotating shaft 8 is installed inside the bearing seat 6, and a loading tray 9 is fixedly connected to one end of the rotating shaft 8. An expansion and contraction assembly is installed on the surface of the loading tray 9, and the expansion and contraction assembly is connected to four expansion and contraction retaining rings 17. An iron strip body 20 is welded to the surface of each of the four expansion and contraction retaining rings 17. Four sliding grooves 21 are formed on the surface of the iron strip body 20, and a sliding bar 22 is slidably connected inside each of the four sliding grooves 21. The two ends of the sliding bar 22 are slidably connected to two iron strip bodies 20 respectively, and a limiting plate 23 is welded to the two ends of the sliding bar 22 respectively. The iron strip body 20 is connected to each other by the slide groove 21, slide bar 22 and limiting plate 23 into a whole, and then welded to the expansion and contraction retaining ring 17. When the iron strip body 20 is subjected to external force during the feeding process, because they are connected to each other by the slide groove 21, slide bar 22 and limiting plate 23 into a whole, these forces can be effectively distributed to the other three iron strip bodies 20. This not only reduces the burden on individual welding points, but also reduces the risk of weld failure caused by local stress concentration, greatly enhances the welding strength, and effectively prevents the iron strip from failing due to insufficient contact surface during feeding. Because the iron strip bodies 20 form a more robust whole structure, even if a small crack or loosening occurs in a certain part, the whole structure can still remain intact, greatly reducing the possibility of the iron strip flying off due to weld failure. This mechanism not only enhances the connection strength between the various components, but also improves the rigidity and stability of the entire structure, enabling the equipment to operate safely at higher speeds and under greater loads.
[0024] Please see Figures 1-3In this embodiment, the height adjustment component includes an electric push rod 2 and telescopic rods 3. The electric push rod 2 is installed on the upper end of the base plate 1, and the output end of the electric push rod 2 is connected to the worktable 4. The electric push rod 2 is the key component for height adjustment. The height of the worktable 4 can be precisely controlled by the extension and retraction of the electric push rod 2, thereby adapting to different operating requirements. Four telescopic rods 3 are installed on the upper end of the base plate 1, and the upper ends of the four telescopic rods 3 are connected to the worktable 4. In order to further enhance the stability of movement and ensure the verticality of movement, these telescopic rods 3 can not only extend and retract synchronously with the movement of the electric push rod 2, but also provide additional support points to ensure that the worktable 4 can remain horizontal and stable at different heights. A support block 7 is welded to the upper surface of the worktable 4. The other end of the rotating shaft 8 is rotatably connected to the support block 7 through a bearing. The support block 7 provides a stable support point for the rotating shaft 8. The support block 7 is equipped with a bearing, which allows the rotating shaft 8 to rotate freely inside it, so that the loading tray 9 can rotate smoothly, which facilitates the unfolding process of the roll material.
[0025] Please see Figures 1-5In this embodiment, the expansion and contraction assembly includes a motor 10, a lead screw 11, a moving block 12, a connecting block 13, a first steering component 14, a connecting rod 15, and a second steering component 16. The motor 10 is mounted on the surface of the loading tray 9. The output end of the motor 10 is connected to the lead screw 11. Two moving blocks 12 are threadedly connected to the surface of the lead screw 11. The motor 10 drives the lead screw 11 to rotate, thereby causing the threaded moving blocks 12 to move linearly. The moving blocks 12 move along the axial direction of the lead screw 11, thereby driving the motor connected to the moving blocks 12 to move linearly. The structure moves, and four connecting blocks 13 are welded to the surface of the moving block 12. A steering component 14 is installed at the end of the connecting block 13 away from the moving block 12. The moving block 12 is rotatably connected to one end of the connecting rod 15 through the steering component 14. A steering component 2 16 is installed at the other end of the connecting rod 15. An expansion and contraction retaining ring 17 is welded to the surface of the two steering components 2 16. The connecting block 13 not only provides an installation position for the steering component 14, but also ensures a stable connection between it and the moving block 12. The steering component 14 and the steering component 2 16 allow connection. The connecting rod 15 changes its angle when the moving block 12 moves, thereby adjusting the position and diameter of the expansion and contraction retaining ring 17. The connecting rod 15 transmits force when the moving block 12 moves, allowing the expansion and contraction retaining ring 17 to expand or contract as needed. When the motor 10 drives the lead screw 11 to rotate, causing the moving block 12 to move, the angle of the connecting rod 15 changes, thus changing the diameter of the expansion and contraction retaining ring 17 to adapt to the feeding operation of the rolled material. A fixing frame 18 is welded to the surface of the loading tray 9, and the connecting block 13 is slidably connected to the fixing frame 18. Four fixing plates 19 are welded to the surface of the loading tray 9. The four fixing plates 19 are rotatably connected to the two connecting rods 15. The fixing frame 18 is welded to the surface of the loading tray 9, providing a frame structure that allows the connecting block 13 to slide inside it, increasing the stability of the device and ensuring the smoothness of the connecting block 13 during movement. The fixing plates 19 are welded to the surface of the loading tray 9. The fixing plates 19 are rotatably connected to the two connecting rods 15, allowing the connecting rods 15 to rotate freely when adjusting the diameter of the expansion and contraction retaining ring 17.
[0026] During operation, the four iron strip bodies 20 are interconnected as a whole through the slide groove 21, slide bar 22, and limiting plate 23, and then welded to the expansion and contraction retaining ring 17. When the iron strip body 20 is subjected to external force during the feeding process, this force can be effectively distributed to the other three iron strip bodies 20, reducing the burden on individual welding points and reducing the risk of weld failure due to local stress concentration. Because the iron strip bodies 20 form a more robust integral structure, even if a small crack or loosening occurs in a certain part, the entire structure can still remain intact, greatly reducing the possibility of the iron strips flying off due to weld failure. This mechanism not only enhances the connection between the various components, but also... The connection strength is enhanced, improving the rigidity and stability of the entire structure, enabling the equipment to operate safely at higher speeds and under greater loads. The electric push rod 2 is a key component for height adjustment; its extension and retraction allow for precise control of the worktable 4's height, adapting to different operational needs. The telescopic rods 3 further enhance movement stability and ensure verticality. These telescopic rods 3 not only extend and retract synchronously with the electric push rod 2 but also provide additional support points, ensuring the worktable 4 remains level and stable at different heights. The support block 7 provides a stable support point for the rotating shaft 8. Bearings are installed inside the support block 7, allowing the rotating shaft 8 to move freely within its internal structure. The rotation allows the loading tray 9 to rotate smoothly, facilitating the unwinding process of the roll material. The motor 10 drives the lead screw 11 to rotate, thereby causing the threadedly connected moving block 12 to move linearly. The moving block 12 moves along the axial direction of the lead screw 11, thus moving the mechanism connected to it. The connecting block 13 not only provides an installation position for the first steering component 14 but also ensures a stable connection between it and the moving block 12. The first steering component 14 and the second steering component 16 allow the connecting rod 15 to change its angle when the moving block 12 moves, thereby adjusting the position and diameter of the expansion and contraction retaining ring 17. The connecting rod 15 transmits force when the moving block 12 moves, causing the expansion and contraction retaining ring... 17 can be expanded or reduced as needed. When the motor 10 drives the lead screw 11 to rotate, causing the moving block 12 to move, the angle of the connecting rod 15 changes, thereby changing the diameter of the expansion and contraction retaining ring 17 to adapt to the roll material feeding operation. The fixing frame 18 is welded to the surface of the loading tray 9, providing a frame structure that allows the connecting block 13 to slide inside it, increasing the stability of the device and ensuring the smoothness of the connecting block 13 during movement. Four fixing plates 19 are welded to the surface of the loading tray 9. The fixing plates 19 form a rotatable connection with the two connecting rods 15, allowing the connecting rods 15 to rotate freely when adjusting the diameter of the expansion and contraction retaining ring 17.
[0027] Through the above steps, the four iron strip bodies 20 are connected to each other as a whole through the slide groove 21, slide bar 22 and limiting plate 23, and then welded to the expansion and contraction retaining ring 17. When the iron strip body 20 is subjected to external force during the feeding process, the force can be effectively distributed to the other three iron strip bodies 20, reducing the burden on individual welding points and reducing the risk of weld failure due to local stress concentration. Since the iron strip bodies 20 form a more robust whole structure, even if a small crack or loosening occurs in a certain part, the whole structure can still remain intact, greatly reducing the possibility of the iron strip flying off due to weld failure. This mechanism not only enhances the connection strength between various components, but also improves the rigidity and stability of the entire structure, enabling the equipment to operate safely at higher speeds and greater loads, thus solving the common problem of easy weld failure and iron strip flying off during feeding of the expansion and contraction inner baffle plate, which poses a safety hazard.
