Description

Technical Field

[0001] This utility model relates to the technical field of rust removal devices, specifically a rust removal device for reinforcing bars. Background Technology

[0002] Steel bars are a material used in large quantities during construction. They are typically stored at construction sites and exposed to air. Even with rust prevention measures implemented before leaving the factory, corrosion is still inevitable during actual use. When using steel bars, it's necessary to remove rust from the corroded areas to prevent further rusting. Currently, rust removal is generally done manually by workers. This method cannot guarantee that all surfaces of the steel bars are rust-free, and it's physically demanding for workers, making it unsuitable for handling large batches of steel bars. Therefore, an automated rust removal device is needed to replace manual methods and remove rust from all surfaces of the steel bars.

[0003] Therefore, this application proposes a steel bar rust removal device. Utility Model Content

[0011] Furthermore, a load-bearing base is fixedly connected to the bottom of the frame.

[0012] Furthermore, the guiding and conveying mechanism includes:

[0013] Guide rollers are rotatably connected to the opposite ends of the frame in pairs via mounting pivots, and the two sets of guide rollers correspond to the opposite ends of the axial direction of the rust removal cylinder.

[0030] This utility model uses a guiding and conveying mechanism to transport the steel bars to be derusted into the derusting cylinder. Then, the derusting cylinder is driven to rotate by a rotation drive mechanism, so that the derusting brushes inside the derusting cylinder can remove rust from the surface of the steel bars. During the derusting process, the steel bars are continuously transported by the guiding and conveying mechanism, eliminating the need for workers to feed the materials.

[0040] 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.

[0041] Please see Figures 1-6 This utility model provides a technical solution: a steel bar rust removal device, including a load-bearing base 1, a frame 2 welded on the load-bearing base 1, a top plate 8 welded to the top of the frame 2, and two pivots horizontally rotatably connected to each of the two opposite ends of the frame 2. The two pivots on the same side are arranged sequentially from top to bottom, and each pivot is fitted with a guide roller 5. The guide roller 5 has an annular guide groove 10 around its periphery. The guide grooves 10 on two guide rollers in the same group form a material passage. Two adjacent guide rollers 5 form a group, thus the frame 2 is equipped with two groups of guide rollers 5. The inner walls of the opposite sides of the frame 2 are connected to slide rails by horizontal screws. Sliders are slidably installed on the slide rails. The two sliders are connected to the connecting seat 14 by screws. Two mounting sleeves 20 are welded on the connecting seat 14. Each of the two mounting sleeves 20 is equipped with a bearing. The two bearings are inserted into the rust removal cylinder 3, so that the rust removal cylinder 3 is rotatably connected to the two mounting sleeves 20. The inner wall of the rust removal cylinder 3 is provided with multiple rust removal bristles 19. The rust removal bristles 19 can be made of steel wire. The rust removal cylinder 3 is located between the two sets of guide rollers 5, and the material inlet is coaxial with the rust removal cylinder 3.

[0042] Each of the four pivots is fitted with a transmission gear 4, and two adjacent transmission gears 4 mesh externally. In addition, one guide roller 5 in each group is driven to rotate by an external drive motor. Thus, the two guide rollers 5 in the same group have the same rotation speed but opposite directions. When removing rust, the worker inserts one end of the steel bar to be removed into the feed port of one of the guide rollers 5. As the guide roller 5 rotates, it bites the steel bar, causing it to be bitten into the guide groove 10 of the guide roller 5, and then the steel bar is fed into the rust removal cylinder 3. Furthermore, the guide roller 5 can be made of rubber material, so that the friction between the surface of the guide roller 5 and the surface of the steel bar is large, which allows the steel bar to be transported into the rust removal cylinder 3 more smoothly.

[0043] A fixed gear 15 is sleeved on the rust removal cylinder 3, and the fixed gear 15 is located between two mounting sleeves 20. A motor base is welded on the top plate 8, and a motor 7 is mounted on the motor base. A drive gear 6 is sleeved on the output shaft of the motor 7. A clearance groove is opened on the top plate 8 to allow the drive gear 6 to pass freely. In addition, the drive gear 6 meshes with the fixed gear 15. When the motor 7 starts, the output shaft of the motor 7 rotates and drives the drive gear 6 to rotate, so that the drive gear 6 and the fixed gear 15 mesh and transmit power, thereby driving the rust removal cylinder 3 to rotate. During the rotation, the rust removal brush 19 can remove rust from the rusted parts on the surface of the steel bar. Since the rust removal cylinder 3 is rotating, the rust removal brush 19 can effectively remove rust from all surfaces of the steel bar.

[0044] A locking ring 9 is sleeved on one end of the rust removal cylinder 3 along its axial direction. Two lugs are symmetrically welded around the periphery of the locking ring 9 along its axial direction. Mounting posts 17 extending outward along the axial direction of the rust removal cylinder 3 are fixed on the lugs. Rollers 18 are rotatably connected to the mounting posts 17. A fixing ring 11 is connected to the frame 2. Multiple protrusions 16 are fixed on the end face of the fixing ring 11 facing the roller 18. A collar 12 is connected to the frame 2. The collar 12 is located on the outer side of the end of the rust removal cylinder 3 away from the locking ring 9. A spring 13 is provided between the collar 12 and the end face of a mounting sleeve 20. The two ends of the spring 13 in the direction of the spring force are respectively welded to the end faces of the collar 12 and the mounting sleeve 20.

[0045] When the rust-removing cylinder 3 rotates, it synchronously drives the locking ring 9 to rotate. When the locking ring 9 rotates, the mounting column 17 rotates around the axis of the rust-removing cylinder 3. Then, through the elastic support of the mounting sleeve 20 by the spring 13, the roller 18 can roll from the end face of the fixed ring 11 to the end face of the protrusion 16, and then from the end face of the protrusion 16 to the end face of the fixed ring 11 when the rust-removing cylinder 3 rotates. This allows the rust-removing cylinder 3 to move horizontally back and forth. Through the reciprocating horizontal movement of the rust-removing cylinder 3, the rust-removing brush 19 can remove rust from the surface of the steel bar in multiple directions, improving the accuracy and efficiency of rust removal.

[0046] The working principle of this utility model is as follows: Start the external drive motor, which drives two sets of guide rollers 5 to rotate. Each set of guide rollers 5 is driven by the meshing of the transmission gear 4, so that the two guide rollers 5 in each set rotate at the same speed but in opposite directions. Then, the worker inserts one end of the steel bar to be derusted into the feeding port of one set of guide rollers 5. As the guide rollers 5 rotate, they bite the steel bar, so that the steel bar is bitten into the guide groove 10 of the guide rollers 5, and then the steel bar is sent into the derusting cylinder 3.

[0047] When the motor 7 is started, its output shaft rotates, driving the drive gear 6 to rotate. This causes the drive gear 6 and the fixed gear 15 to mesh and drive the rust removal cylinder 3 to rotate. During rotation, the rust removal brush 19 removes rust from the rusted areas on the surface of the reinforcing bar. Since the rust removal cylinder 3 rotates, the rust removal brush 19 can effectively remove rust from all surfaces of the reinforcing bar. When the rust removal cylinder 3 rotates, it synchronously drives the locking ring 9 to rotate. When the locking ring 9 rotates, the mounting column 17 rotates around the axis of the rust removal cylinder 3. The elastic support of the mounting sleeve 20 by the spring 13 causes the roller 18 to roll from the end face of the fixed ring 11 to the end face of the protrusion 16, and then from the end face of the protrusion 16 back to the end face of the fixed ring 11. This causes the rust removal cylinder 3 to move horizontally back and forth. Through the reciprocating horizontal movement of the rust removal cylinder 3, the rust removal brush 19 can remove rust from the surface of the reinforcing bar in multiple directions, improving the accuracy and efficiency of rust removal.
