Description

Technical Field

[0001] This invention relates to the technical field of automated feeding equipment for steel bar straightening, specifically an automated feeding machine for steel bar straightening. Background Technology

[0002] Steel bars are long strips of steel with multiple cross-sections, possessing high strength and ease of processing, and are widely used in industrial fields. Steel bars are long, rectangular metal materials made of steel, typically with circular, square, or hexagonal cross-sections. They are widely used in construction, machinery manufacturing, and the automotive industry, commonly used to make shafts, bolts, and structural components. Based on differences in material and manufacturing process, they can be classified into carbon steel bars, alloy steel bars, stainless steel bars, etc. They possess high strength, wear resistance, and good machinability.

[0003] Most existing conventional automatic lifting and feeding mechanisms rely solely on a single lifting plate to push and convey steel bars. During the lifting and conveying process, the upper steel bars can easily slip down into the feeding channel, leading to bar stacking and multiple bars entering the straightener simultaneously. This situation can easily cause scratches on the surface of the steel bars due to mutual collisions, and in severe cases, it can even cause the straightening rollers to jam, adversely affecting equipment operation. Furthermore, most equipment lacks a flexible, openable ring structure for temporary positioning of individual steel bars. After the steel bars are lifted into position, their placement is prone to deviation, making it difficult to accurately align them with the straightener's feeding port. This often requires manual adjustment and alignment by staff, increasing the frequency of on-site human intervention. Summary of the Invention

[0009] Furthermore, the guiding device includes a slide rod, the end of which is fixedly connected to the surface of the feeding ring sleeve. The inner wall of the feeding box is provided with a sliding groove, and a guide telescopic rod is fixedly connected to the inner wall of the sliding groove. An elongated plate is fixedly connected to the end of the slide rod away from the feeding ring sleeve. A movable rod is slidably connected to the inner wall of the elongated plate. A spring plate is fixedly connected to the end of the movable rod. A guide ring plate is fixedly connected to the end of the movable rod away from the spring plate.

A guide support plate is hinged to the end of the inclined plate away from the guide ring plate. A pulley is rotatably connected to the inner wall of the guide support plate.

[0010] Furthermore, the surface of the slide rod is slidably connected to the inner wall of the slide groove, the end of the guide telescopic rod away from the slide groove is fixedly connected to the surface of the slide rod, and the end of the spring plate away from the moving rod is fixedly connected to the surface of the elongated plate.

[0011] Furthermore, the feeding device includes a storage box, the surface of which is fixedly connected to the surface of the feeding box. A feeding port is provided on the inner wall of the feeding box. An elastic rod is fixedly connected to the inner wall of the storage box. A limit push plate is fixedly connected to the end of the elastic rod away from the storage box. A second motor is fixedly connected to the inner wall of the support frame. A lifting rail is fixedly connected to the inner wall of the storage box. A support block is fixedly connected to the surface of the storage box. A circular telescopic rod is fixedly connected to the bottom of the support block. A rack is fixedly connected to the end of the circular telescopic rod away from the support block. A multi-segment rod is fixedly connected to the surface of the rack. A rotating rod is fixedly connected to the output end of the second motor. A gear is fixedly connected to the surface of the rotating rod. A second threaded rod is fixedly connected to the end of the rotating rod away from the second motor. A force-applying rod is threadedly connected to the surface of the second threaded rod. A push plate is fixedly connected to the end of the force-applying rod. A tension rod is fixedly connected to the surface of the push plate. A lifting wheel is slidably connected to the inner wall of the lifting rail.

[0012] Furthermore, the inner wall of the feeding port is adapted to the surface of the blocking door, the bottom of the pusher plate is in contact with the bottom of the inner wall of the storage box, the end of the tension rod away from the pusher plate is fixedly connected to the inner wall of the storage box, the surface of the rack is meshed with the surface of the gear, and the end of the multi-segment rod away from the rack is fixedly connected to the surface of the lifting wheel.

[0013] The present invention has the following beneficial effects: This invention features an independent storage box for batch storage of steel bars. A second motor synchronously drives two sets of linkage mechanisms. On one hand, the steel bars are pushed to the feeding box via the second threaded rod and the pusher plate. On the other hand, the lifting wheel and the blocking door are linked by gears, racks, and multi-segment rods. The door opens automatically when pushing the material and closes automatically when retracting.

[0014] This invention features a precise matching between the blocking gate and the feeding port, accurately isolating the storage box and the feeding box. This prevents multiple steel bars from simultaneously entering the feeding box and causing stacking and jamming. The internal elastic rod and limiting push plate continuously hold the steel bars in place, preventing them from tilting or misaligning within the storage box. This ensures that only one steel bar is pushed at a time, achieving uninterrupted automatic material replenishment. This significantly reduces the frequency of manual feeding and is suitable for continuous straightening operations on production lines. The baffle, inclined plate, and elastic rod form a linked material distribution structure. The feeding plate lifts the steel bar and pushes open the baffle. The baffle then presses against the inclined plate and opens the feeding ring. After a single steel bar falls into the ring, the feeding plate descends, and the elastic rod drives the baffle to automatically reset. The baffle isolates any remaining steel bars behind it, strictly ensuring that only one steel bar is fed at a time. This eliminates the possibility of equipment jamming and steel bar collision and deformation caused by multiple steel bars entering the straightening station simultaneously.

[0015] The present invention features a curved pulley inside the guide ring plate and an inclined plate, guide support plate, and support pulley on the outside, forming a double-layer rolling support structure. During the pushing of the steel bar, full rolling friction is achieved, which greatly reduces the pushing resistance of the steel bar and avoids scratches on the surface of the steel bar. The guide support plate rises and falls synchronously with the opening and closing of the ring plate, lifting the steel bar from the bottom and restricting the vertical and horizontal deviation of the steel bar throughout the process, ensuring the straight conveying of the steel bar, improving the straightening accuracy of the subsequent straightening machine, and reducing the straightening scrap rate.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 11 As shown, the present invention is an automated feeding machine for straightening steel bars, including a base 1, a feeding box 2 fixedly connected to the top of the base 1, a straightening machine 3 set on the top of the base 1, a bracket 4 fixedly connected to the bottom of the base 1, a support frame 5 fixedly connected to the surface of the base 1, a feeding device 6 set above the base 1, a guiding device 7 set above the base 1, and a feeding device 8 set above the base 1. The feeding device 6 includes a motor 20. When the motor 20 is turned on, its output end drives the threaded rod 21 to rotate. When the threaded rod 21 rotates, it drives the feeding plate 22 to move inside the feeding box 2 through the thread. At this time, when the feeding plate 22 moves, it drives the steel bar that needs to be straightened inside the feeding box 2 to move together, so that the feeding plate 22 pushes the steel bar to contact the baffle 28. Then, if it continues to move upward, it will push the baffle 28 to rotate on the surface of the thin rod 27, thereby completing the feeding work. The surface of the motor 20 and the bracket 4 The inner wall of the feeding box 2 is fixedly connected, and the output end of the motor 20 is fixedly connected to a threaded rod 21. The surface of the threaded rod 21 is threadedly connected to a feeding plate 22. The inner wall of the feeding box 2 has a slot 23, and the inner wall of the slot 23 is fixedly connected to a telescopic rod 24. The telescopic rod 24 and the retractable rod 31 respectively make the position of the feeding plate 22 and the feeding ring 32 more stable when they move. When the one-way electric push rod 34 is opened, the output end drives the push plate 35 to move, thereby pushing the soft pad 36, which in turn pushes the feeding ring. The steel rod inside the feed box 32 moves towards the output end of the straightener 3. A compression spring 25 is fixedly connected to the inner wall of the feed box 2. A push plate 26 is fixedly connected to the end of the compression spring 25 away from the feed box 2. A thin rod 27 is fixedly connected to the inner wall of the feed box 2. A baffle 28 is rotatably connected to the surface of the thin rod 27. When the baffle 28 rotates upward, its surface contacts the surface of the inclined plate 37, thereby pushing the feed ring 32 to squeeze the spring rod 30 to perform separation work, allowing the steel rod to enter the interior of the feed ring 32. When the steel rod enters... When the steel bars are inserted into the feeding ring 32, the feeding plate 22 moves the remaining steel bars downwards, releasing the pressure on the baffle 28. The baffle 28 will reset through the elastic force of the elastic rod 29. At the same time, when the baffle 28 resets, it will release the pressure on the inclined plate 37, so that the feeding ring 32 will move closer to each other through the squeezing force of the spring rod 30, so that the straightener 3 can clamp and guide the steel bars inside. The inner wall of the feeding box 2 is fixedly connected to the elastic rod 29, and the inner wall of the feeding box 2 is fixedly connected to the spring rod 30.

[0022] A retractable rod 31 is fixedly connected to the inner wall of the feeding box 2. A feeding ring 32 is fixedly connected to the end of the retractable rod 31 away from the feeding box 2. A support frame 33 is fixedly connected to the upper surface of the feeding box 2. A one-way electric push rod 34 is fixedly connected to the inner wall of the support frame 33. A push plate 35 is fixedly connected to the output end of the one-way electric push rod 34. A soft pad 36 is fixedly connected to the end of the push plate 35. A sloping panel 37 is fixedly connected to the bottom of the feeding ring 32.

[0023] The surface of the feeding plate 22 is adapted to the inner wall of the slot 23, the end of the telescopic rod 24 away from the slot 23 is fixedly connected to the top of the feeding plate 22, and the end of the elastic rod 29 away from the feeding box 2 is fixedly connected to the surface of the baffle 28.

[0024] The end of the spring rod 30 away from the feeding box 2 is fixedly connected to the surface of the feeding ring 32. The surface of the inclined panel 37 is adapted to the surface of the baffle 28. There are two push plates 26. The feeding plate 22 is located in a position close to each other between the two push plates 26.

[0025] The guiding device 7 includes a slide rod 40. When the slide rod 40 moves, it pushes the elongated plate 43, causing the spring plate 45 to pull the moving rod 44, which in turn pulls the guide ring plate 46 to move together. This ensures that the clamping size of the guide ring plate 46 matches the clamping size of the feeding ring sleeve 32, allowing the machine to effectively guide and clamp steel bars of different sizes. The end of the slide rod 40 is fixedly connected to the surface of the feeding ring sleeve 32. The inner wall of the feeding box 2 has a groove 41, and a guide telescopic rod 42 is fixedly connected to the inner wall of the groove 41. The end of the slide rod 40 away from the feeding ring sleeve 32 is fixedly connected to an elongated plate 45. The inner wall of the elongated plate 43 is slidably connected to a moving rod 44. The end of the moving rod 44 is fixedly connected to a spring plate 45. The end of the moving rod 44 away from the spring plate 45 is fixedly connected to a guide ring plate 46. The inner wall of the guide ring plate 46 is rotatably connected to a curved pulley 47. When the curved pulley 47 and pulley 50 push the steel rod inside the guide ring plate 46 to move, the friction between them is reduced. The surface of the guide ring plate 46 is hinged to an inclined plate 48. The end of the inclined plate 48 away from the guide ring plate 46 is hinged to a guide support plate 49. The inner wall of the guide support plate 49 is rotatably connected to a pulley 50.

[0026] The surface of the slide rod 40 is slidably connected to the inner wall of the slide groove 41, the end of the guide telescopic rod 42 away from the slide groove 41 is fixedly connected to the surface of the slide rod 40, and the end of the spring plate 45 away from the moving rod 44 is fixedly connected to the surface of the elongated plate 43.

[0027] The feeding device 8 includes a storage box 60, the surface of which is fixedly connected to the surface of the feeding box 2. A feeding port 61 is provided on the inner wall of the feeding box 2. An elastic round rod 62 is fixedly connected to the inner wall of the storage box 60. A limit push plate 63 is fixedly connected to the end of the elastic round rod 62 away from the storage box 60. A second motor 64 is fixedly connected to the inner wall of the support frame 5. When the second motor 64 is turned on, its output end drives the rotating rod 75 to rotate, thereby causing the rotating rod 75 to drive the second threaded rod 66 to rotate together. When the second threaded rod 66 rotates, it drives the force application rod 67 to move through the thread. When the force bar 67 moves, it pushes the pusher plate 68 to move inside the storage box 60, thereby pushing the steel bars stored inside the storage box 60 to move into the loading box 2, thus completing the loading operation inside the loading box 2. A lifting rail 65 is fixedly connected to the inner wall of the storage box 60, and a support block 70 is fixedly connected to the surface of the storage box 60. A circular telescopic rod 71 is fixedly connected to the bottom of the support block 70, and a rack 72 is fixedly connected to the end of the circular telescopic rod 71 away from the support block 70. A multi-segment rod 73 is fixedly connected to the surface of the rack 72. A second motor 64... The output end is fixedly connected to a rotating rod 75. When the rotating rod 75 rotates, it drives the gear 76 to rotate as well, thereby driving the rack 72 to move through meshing. When the rack 72 moves, it pushes the lifting wheel 77 up and down inside the lifting rail 65 through the multi-segment rod 73. This causes the lifting wheel 77 to drive the blocking door 74 to move together. As the machine pushes the steel bar into the upper feeding box 2 by the pusher plate 68, the blocking door 74 moves upward and separates from the feeding port 61, allowing the steel bar to enter the upper feeding box 2 and wait for the next process. Conversely, when the feeding is completed, the pusher plate 68 moves upward and separates from the feeding port 61. 8 moves backward, and the blocking door 74 moves downward, so that the surface of the blocking door 74 contacts the feeding port 61 to block the steel bar. The surface of the rotating rod 75 is fixedly connected to the gear 76, and the end of the rotating rod 75 away from the second motor 64 is fixedly connected to the second threaded rod 66. The surface of the second threaded rod 66 is threadedly connected to the force-applying rod 67, and the end of the force-applying rod 67 is fixedly connected to the push plate 68. The surface of the push plate 68 is fixedly connected to the tension rod 69. The inner wall of the lifting rail 65 is slidably connected to the lifting wheel 77, and the end of the lifting wheel 77 is fixedly connected to the blocking door 74.

[0028] The inner wall of the feeding port 61 is adapted to the surface of the blocking door 74, the bottom of the pusher plate 68 is in contact with the bottom of the inner wall of the storage box 60, the end of the tension rod 69 away from the pusher plate 68 is fixedly connected to the inner wall of the storage box 60, the surface of the rack 72 is meshed with the surface of the gear 76, and the end of the multi-segment rod 73 away from the rack 72 is fixedly connected to the surface of the lifting wheel 77.

[0029] In operation, when the motor 20 is turned on, its output end drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the feeding plate 22 to move inside the feeding box 2 via the thread. This movement of the feeding plate 22 moves the steel bars inside the feeding box 2 that need straightening, causing the feeding plate 22 to push the steel bars into contact with the baffle 28. Continuing to move upwards pushes the baffle 28 to rotate on the surface of the thin rod 27, thus completing the feeding process. Simultaneously, the push plate 26 uses the spring force of the compression spring 25 to correct the position of the steel bars, preventing misalignment and blockage of the steel bars above the feeding plate 22, which would affect the machine's feeding operation. Also, when the steel bars push the baffle 28 to rotate, the upward rotating surface of the baffle 28 will contact the surface of the inclined plate 37. The surfaces make contact, pushing the feeding ring 32 to squeeze the spring rod 30, thus separating the steel bars and allowing them to enter the interior of the feeding ring 32. When the steel bars enter the interior of the feeding ring 32, the feeding plate 22 moves the remaining steel bars downwards, releasing the pressure on the baffle 28. The baffle 28 will then reset due to the elastic force of the elastic rod 29. At the same time, when the baffle 28 resets, it will release the pressure on the inclined plate 37, causing the feeding rings 32 to move closer together due to the squeezing force of the spring rod 30. This allows the straightener 3 to clamp and guide the steel bars inside. Simultaneously, the reset baffle 28 blocks the remaining steel bars above the feeding plate 22, preventing the machine from feeding multiple steel bars at once and causing blockages. This makes the straightening and feeding of steel bars more stable. Simultaneously, the telescopic rod 24 and the retractable rod 31 make the positions of the feeding plate 22 and the feeding ring 32 more stable when they move. When the one-way electric push rod 34 is opened, the output end drives the push plate 35 to move, thereby pushing the soft pad 36, which in turn pushes the steel bar inside the feeding ring 32 towards the output end of the straightener 3. This allows the machine to quickly complete the straightening work of the steel bar, improving the machine's working efficiency and stability. When the feeding ring 32 moves, it drives the slide rod 40 to move inside the slide groove 41. When the slide rod 40 moves, it pushes the elongated plate 43, causing the spring plate 45 to pull the moving rod 44 to move. This causes the moving rod 44 to pull the guide ring plate 46 to move together, making the clamping size of the guide ring plate 46 consistent with the clamping size of the feeding ring 32. The machine effectively guides and clamps steel bars of different sizes. When the guide ring plate 46 guides and clamps the steel bars, it pushes the moving rod 44 by squeezing, pulling the spring plate 45 outward. This prevents excessive squeezing of the steel bars by the guide ring plate 46, which could cause deformation or affect feeding. Simultaneously, when the guide ring plates 46 move closer or further apart, they squeeze or pull the inclined plate 48, causing the guide support plate 49 to move up and down. This further supports the steel bars inside the guide ring plate 46, making the steel bars more stable during straightening and preventing positional shifts that could affect the straightening effect. Additionally, the curved pulley 47 and pulley 50 reduce friction when the soft pad 36 pushes the steel bars inside the guide ring plate 46.To improve the stability of the machine's pushing of steel bars and increase the efficiency of steel bar feeding, when the second motor 64 is turned on, its output end drives the rotating rod 75 to rotate, which in turn drives the second threaded rod 66 to rotate. The rotation of the second threaded rod 66 drives the force-applying rod 67 to move via its threads. The force-applying rod 67 pushes the pusher plate 68 inside the storage box 60, thus pushing the steel bars stored inside the storage box 60 into the loading box 2, completing the feeding operation. The tension rod 69 makes the position of the pusher plate 68 more stable during movement. Simultaneously, the rotation of the rotating rod 75 drives the gear... The gear 76 rotates together, thereby driving the rack 72 to move through meshing. As the rack 72 moves, it pushes the lifting wheel 77 up and down inside the lifting rail 65 via the multi-segment rod 73. This causes the lifting wheel 77 to move the blocking gate 74 along with the lifting wheel 77. When the pusher plate 68 pushes the steel bar into the feeding box 2, the blocking gate 74 moves upward, separating from the feeding port 61, allowing the steel bar to enter the feeding box 2 and await the next process. Conversely, when feeding is complete, the pusher plate 68 moves backward, and the blocking gate 74 moves downward, bringing its surface into contact with the feeding port 61 to block the steel bar and improve the stability of the machine's feeding process.
