Description

Technical Field

[0001] This utility model relates to the field of removing binding ropes from bundled steel bars, specifically a wire-pulling mechanism for binding ropes used in bundled steel bars. Background Technology

[0002] In engineering fields such as construction, bridges, and rail transit, steel bars are typically transported and stored in bundles for easy handling and on-site construction. To prevent loosening, bundled steel bars are commonly secured with binding wire during production or stacking. This binding wire is generally made of low-carbon steel wire, which possesses a certain degree of flexibility and strength, enabling it to form a stable bond when the steel bars are stacked.

[0003] After the steel bars are produced, multiple steel bars are usually tied together with wire to facilitate transportation. When in use, the wire needs to be removed to make it easier to take out the steel bars. However, the removal of the wire usually requires manual operation. Operators use pliers or hand-held knives to cut the wire, which is time-consuming and laborious, and it is also inconvenient to pull out the wire.

[0004] Therefore, a wire-drawing mechanism for binding ropes for bundled steel bars is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire-pulling mechanism for bundling ropes of steel bars. This mechanism solves the problem that after steel bars are produced, multiple steel bars are usually bound together with wire for easy transportation. However, when in use, the wire needs to be removed to facilitate the removal of the steel bars. Removing the wire usually requires manual operation, with operators using pliers or hand-held knives to cut the wire, which is time-consuming, laborious, and inconvenient to pull out.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a conveyor belt, a crossbeam at the top of the conveyor belt, a lifting arm slidably connected to one side of the crossbeam, a lever arm fixedly connected to the bottom of the lifting arm, a steel bar bundle at the front of the lever arm, the steel bar bundle including binding wire, a slide at the bottom of the lever arm, and a wire-drawing mechanism at the bottom of the slide. The wire-drawing mechanism includes a base plate, a cylinder, a connecting plate, a wire-drawing knife, and a fixed shaft. The base plate is fixedly connected to the bottom of the slide, the cylinder is fixedly connected to one side of the base plate, the connecting plate is rotatably connected to one end of the piston rod of the cylinder via a shaft, the wire-drawing knife is hinged to one end of the connecting plate via a shaft, the fixed shaft is fixedly connected to the bottom of the slide, a visual monitoring module is provided at the bottom of the lever arm, and a bracket is provided on one side of the conveyor belt.

[0017] 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. Example

[0018] Please see Figure 1 - Figure 6 The wire-drawing mechanism for bundling steel bars in this embodiment includes a conveyor belt 1, a crossbeam 2 at the top of the conveyor belt 1, a lifting arm 3 slidably connected to one side of the crossbeam 2, a lever arm 4 fixedly connected to the bottom of the lifting arm 3, a bundle of steel bars including binding wire 5 arranged at the front of the lever arm 4, a slide 6 at the bottom of the lever arm 4, and a wire-drawing mechanism at the bottom of the slide 6. The wire-drawing mechanism includes a base plate 7, a cylinder 8, a connecting plate 9, a wire-drawing knife 10, and a fixed shaft 11. The base plate 7 is fixedly connected to the bottom of the slide 6, and the cylinder 8 is fixedly connected to one side of the base plate 7. The connecting plate 9 is rotatably connected to one end of the piston rod of the cylinder 8 via a shaft. The wire drawing knife 10 is hinged to one end of the connecting plate 9 via a shaft. The fixed shaft 11 is fixedly connected to the bottom of the slide 6. A vision monitoring module 17 is provided at the bottom of the lever arm 4. A bracket 18 is provided on one side of the conveyor belt 1. A moving component is provided at the connection between the lifting arm 3 and the crossbeam 2. The moving component ensures that the lifting arm 3 can move left and right on the crossbeam 2, which facilitates the vision monitoring module 17 to identify the position of the binding wire 5 on the steel bar bundle, thereby determining the position of the lever arm 4 and facilitating the cutting and removal of the binding wire 5.

[0019] The steel bar bundle is placed on top of the bracket 18. After the binding wire 5 on the steel bar bundle is cut by the shearing device, the motor 13 drives the slide 6 to move forward, so that the cut binding wire 5 is placed between the two wire-drawing blades 10. At this time, the cylinder 8 is activated, and the piston rod of the cylinder 8 pushes out, which, together with the connecting plate 9, drives the two wire-drawing blades 10 to close. When the wire-drawing blades 10 are closed, there is an arc-shaped groove at the cutting edge. The arc-shaped groove ensures that the binding wire 5 will not be cut. Afterward, the two wire-drawing blades 10 are still in the closed state, and the slide 6 retracts and stops above the conveyor belt 1. At this time, the wire-drawing blades 10 are released and reset, and the binding wire 5 falls onto the conveyor belt 1 and is transported and recovered, thus completing the effect of removing the binding wire 5.

[0020] Please see Figure 1 - Figure 6 There are two wire drawing cutters 10 and two connecting plates 9. The two connecting plates 9 are respectively set on the upper and lower sides of the piston rod of the cylinder 8. The two wire drawing cutters 10 are set together vertically. The two wire drawing cutters 10 are rotatably connected to the outside of the fixed shaft 11. The piston rod of the cylinder 8 is slidably connected to one side of the base plate 7.

[0021] Please see Figure 1 - Figure 6 A connecting mechanism is provided at the bottom of the slide 6 and the lever arm 4. The connecting mechanism includes a fixing block 12 and a guide rail 15. The fixing block 12 is fixedly connected to the inner top of the slide 6, and the guide rail 15 is fixedly connected to the bottom of the lever arm 4. A motor 13 is fixedly connected to the bottom of the slide 6. A gear 14 is fixedly connected to one end of the output shaft of the motor 13. A rack 16 is fixedly connected to the bottom of the lever arm 4. The gear 14 and the rack 16 are meshed together.

[0022] The motor 13 drives the gear 14 to rotate, which, in conjunction with the rack 16, causes the slide 6 to slide at the bottom of the lever arm 4. The fixed block 12 and the guide rail 15 ensure the temperature during sliding and prevent positional deviation.

[0023] Please see Figure 1 - Figure 6 The inner wall of the fixing block 12 fits against the outer wall of the guide rail 15. The fixing block 12 has a connecting groove inside. The fixing block 12 is slidably connected to the outer side of the guide rail 15 through the connecting groove. The end face of the guide rail 15 is T-shaped. There are two fixing blocks 12 and two guide rails 15.

[0024] The working principle of the above embodiments is as follows: The steel bar bundle is placed on top of the bracket 18. After the binding wire 5 on the steel bar bundle is cut by the shearing device, the motor 13 drives the slide 6 to move forward, so that the cut binding wire 5 is placed between the two wire-drawing blades 10. At this time, the cylinder 8 is started, and the piston rod of the cylinder 8 pushes out, which, together with the setting of the connecting plate 9, drives the two wire-drawing blades 10 to close. When the wire-drawing blades 10 are closed, there is an arc-shaped groove at the cutting edge. The arc-shaped groove ensures that the binding wire 5 will not be cut. Afterwards, the two wire-drawing blades 10 are still in the closed state, and the slide 6 retracts and stops above the conveyor belt 1. At this time, the wire-drawing blades 10 are released and reset, and the binding wire 5 falls onto the conveyor belt 1 and is transported and recycled, thus completing the effect of removing the binding wire 5. The motor 13 drives the gear 14 to rotate, which, in conjunction with the rack 16, causes the slide 6 to slide at the bottom of the lever arm 4. The fixed block 12 and the guide rail 15 ensure the temperature during sliding and prevent positional deviation.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
