Description

Technical Field

[0001] The utility model relates to the technical field of wire pay-off drums, and in particular to a wire pay-off drum for steel bars. Background Art

[0002] In the vast field of building and infrastructure construction, steel bars, as the core material for enhancing structural strength and bearing capacity, play an indispensable role. Steel bars are usually shipped in the form of coils to facilitate transportation and storage. However, in the actual construction process, the demand for straight steel bars is more common because straight steel bars are easy to cut, weld and tie, which can significantly improve construction efficiency and project quality. Therefore, it is necessary to process the coiled steel bars into straight steel bars. During the processing of straight steel bars, a pay-off reel is needed to pay out the coiled steel bars. The pay-off reel can pay out the coiled steel bars in an orderly and stable manner, providing convenience for subsequent steel bar straightening, cutting and other processes.

[0003] Existing devices have some disadvantages during use. For example, the steel bars are laid out passively during the laying process, that is, the steel bars drive the rotating disk and the fixed frame to rotate during the laying process. When the external force fails during the laying process, the rotating disk and the fixed frame will continue to rotate due to the rotational force driven by the steel bars, resulting in the steel bars being entangled and knotted. The steel bars may also break due to excessive torsion. The broken steel bars will not only lead to the failure of laying out, but also pose a safety threat to construction personnel and equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a steel bar pay-off drum, which solves the problem that when an external force fails during the steel bar pay-off process, the rotating disk and the fixed frame continue to rotate due to the rotational force driven by the steel bar.

During specific use, the steel bar to be paid out is placed on the fixed frame 15 to ensure that one end of the steel bar can smoothly pass through the material guide component 3 and enter the working area of ​​the straightening machine. The steel bar drives the fixed frame 15 and the rotating disk 14 to rotate through the pulling of the straightening machine. During the rotation process, the auxiliary component 2 can assist the rotating disk 14 to rotate. At this time, the steel bar is gradually paid out as the rotating disk 14 rotates. According to actual needs, the rotation speed of the rotating disk 14 is adjusted by the control component 4, thereby controlling the payout speed and ensuring a smooth payout process.

The lower end surface of the rotating disk 14 rolls on the roller 209, and the roller 209 provides stable support and guidance for the rotating disk 14 and the fixed frame 15. At the same time, the first bearing 202 and the second bearing 204 respectively reduce the friction between the connecting column 205 and the connecting shaft 13 and between the rotating disk 14 and the support disk 12, so that the rotation of the rotating disk 14 and the fixed frame 15 is smoother.

During specific use, the steel bars to be laid out are placed on the fixed frame 15 to ensure that one end of the steel bars can smoothly enter the material guide tube 303. When the steel bars begin to enter the material guide tube 303, the photoelectric sensor E3JK-DS30 monitors the passage of the steel bars.

[0031] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the control component 4 includes a first connecting block 401 and a second connecting block 402 respectively fixedly connected to the upper end surface of the support plate 12, the first connecting block 401 and the second connecting block 402 are symmetrically arranged, a third connecting block 403 is provided on one side of the second connecting block 402, and the bottom end of the third connecting block 403 is fixedly connected to the upper end surface of the support plate 12, the top of the first connecting block 401 is rotatably connected to the first connecting rod 404, the top of the second connecting block 402 is rotatably connected to the second connecting rod 405, and the top of the third connecting block 403 is rotatably connected to the third connecting rod 406. The control component 4 includes a first auxiliary connecting rod 407 rotatably connected to the second connecting rod 405 at one end away from the second connecting block 402. The first auxiliary connecting rod One end of the rod 407 away from the second connecting rod 405 is rotatably connected to the end of the third connecting rod 406 away from the third connecting block 403, and the end of the third connecting rod 406 away from the first auxiliary connecting rod 407 is rotatably connected to the second auxiliary connecting rod 408. The end of the second auxiliary connecting rod 408 away from the third connecting rod 406 is rotatably connected to the end of the first connecting rod 404 away from the first connecting block 401. The opposite inner walls of the first connecting rod 404 and the second connecting rod 405 are respectively fixedly connected with clamping blocks 409, and the opposite inner walls of the two clamping blocks 409 are respectively fixedly connected with brake pads 410, and the two brake pads 410 are used to control the connecting column 205 to stop rotating. The control component 4 also includes a The L-shaped mounting base 411 on one side of the connecting rod 408, and the lower end surface of the L-shaped mounting base 411 is fixedly connected to the upper end surface of the support plate 12, and the outer wall of the L-shaped mounting base 411 on the side away from the third connecting rod 406 is fixedly connected to the cylinder 412, and the end of the telescopic end of the cylinder 412 away from the cylinder 412 passes through the L-shaped mounting base 411 and is slidably connected to the L-shaped mounting base 411, and the end of the telescopic end of the cylinder 412 away from the cylinder 412 is rotatably connected to the end of the third connecting rod 406 away from the first auxiliary connecting rod 407. During specific use, when it is necessary to stop the rotation of the connecting column 205, the telescopic end is controlled by the cylinder 412 to start to extend, pushing the third connecting rod 406 to move in the direction away from the cylinder 412. As the third connecting rod 406 moves With the movement of the connecting rod 406, the first auxiliary connecting rod 407 and the second auxiliary connecting rod 408 begin to rotate around their rotation connection points respectively. The rotation of the first auxiliary connecting rod 407 drives the second connecting rod 405 to move toward the first connecting rod 404. At the same time, the rotation of the second auxiliary connecting rod 408 drives the first connecting rod 404 to move toward the second connecting rod 405. As the first connecting rod 404 and the second connecting rod 405 move toward each other, the clamping block 409 and the brake pad 410 thereon gradually approach the connecting column 205. When the brake pad 410 is in close contact with the outer surface of the connecting column 205, due to the high friction coefficient of the brake pad 410, the rotation of the connecting column 205 will be hindered and gradually stop.

[0032] Working principle: Place the wire to be laid out on the fixed frame 15 to ensure that one end of the steel bar can smoothly pass through the guide tube 303 and enter the working area of ​​the straightening machine. The photoelectric sensor E3JK-DS30 monitors the passage of the steel bar so as to adjust the wire laying speed in time. The steel bar starts to move under the pull of the straightening machine, and at the same time drives the fixed frame 15 and the rotating disk 14 to rotate. When the rotating disk 14 and the fixed frame 15 rotate, the second connecting hole 207 on the connecting column 205 forms a sliding connection with the connecting shaft 13, allowing the rotating disk 14 to have a certain fine-tuning space in the vertical direction. The lower end face of the rotating disk 14 rolls on the roller 209. The roller 209 provides stable support and guidance for the rotating disk 14 and the fixed frame 15. The first bearing 202 and the second bearing 204 respectively reduce the friction between the connecting column 205 and the connecting shaft 13 and between the rotating disk 14 and the support disk 12, making the rotation smoother. When it is necessary to stop paying out the line, the telescopic end is controlled by the cylinder 412 to start extending, pushing the third connecting rod 406 to move in the direction away from the cylinder 412. As the third connecting rod 406 moves, the first auxiliary connecting rod 407 and the second auxiliary connecting rod 408 respectively start to rotate around their rotation connection points. The rotation of the first auxiliary connecting rod 407 drives the second connecting rod 405 to move in the direction close to the first connecting rod 404. At the same time, the rotation of the second auxiliary connecting rod 408 drives the first connecting rod 404 to move in the direction close to the second connecting rod 405. As the first connecting rod 404 and the second connecting rod 405 move toward each other, the clamping block 409 and the brake pad 410 thereon gradually approach the connecting column 205. When the brake pad 410 is in close contact with the outer surface of the connecting column 205, due to the high friction coefficient of the brake pad 410, the rotation of the connecting column 205 will be hindered and gradually stop.
