Description
Technical Field
[0001] This utility model relates to the field of steel bar processing technology, specifically to an automatic coiling device for steel bar processing. Background Technology
[0002] As an important building material, steel bars refer to steel used in reinforced concrete and prestressed reinforced concrete. They are usually circular in cross-section and have a huge market demand.
[0003] After the steel bars are processed, they need to be coiled. Currently, the devices used for coiling steel bars are relatively complex in structure and have a single function. They cannot change the inner diameter of the steel bar coil according to the actual needs of the steel bars being processed, so they are not very practical. At the same time, after the steel bar coil is formed, many steel bars will be exposed to the inside, making the steel bar coil irregular and resulting in a messy overall structure. Unlike a ring, it occupies a large area and is not convenient for subsequent hoisting and transportation. Utility Model Content

This rewinding device has a simple structure, full functionality, and can limit the inner diameter value of the steel bar during the rewinding process, so that the inner diameter of the steel bar roll can be controlled according to actual needs. It is highly practical. By using multiple rotatable straightening rollers to straighten the position of the exposed part of the inner side of the steel bar roll, the steel bar roll is made more ring-shaped, making the overall shape of the steel bar roll more regular and beautiful. At the same time, it reduces the overall footprint of the steel bar roll, which is convenient for actual hoisting and transportation.

[0025] Please see Figure 1 An embodiment of this utility model is provided: an automatic coiling device for steel bar processing. The coiling device includes a coiling mechanism 1, a rotating mechanism 2, and a straightening mechanism 3. The rotating mechanism 2 is located above the coiling mechanism 1, and multiple sets of straightening mechanisms 3 are provided, all of which are located on the rotating mechanism 2.
[0026] Please see Figure 2 The winding mechanism 1 has a support platform 11 and a central column 12. The central column 12 is fixed to the upper end face of the support platform 11, and a winding motor 13 is fixed on the central column 12. The output end of the winding motor 13 is connected to a synchronous pulley group, which is located inside the central column 12. A winding reel 15 is provided on the central column 12. The winding reel 15 is a cavity structure with an opening at the top and a hollow interior. The winding of the steel bar is completed inside the cavity of the winding reel 15. The installation between the winding reel 15 and the synchronous pulley group is completed inside the central column 12. The rotating mechanism 2 includes a rotating motor 21, which is vertically arranged and fixed to the lower end face of the winding reel 15.
[0027] Please see Figure 3The take-up motor 13 is connected to the central support shaft 14 via a synchronous belt pulley set. The take-up reel 15 is fixed on the central support shaft 14. The central support shaft 14 is located in the cavity of the take-up reel 15 and is vertically arranged. The central support shaft 14 is vertically arranged inside the central column 12. The rotating mechanism 2 also includes a support shaft 22 and a drive gear 23. The output end of the rotating motor 21 is connected to the support shaft 22. The support shaft 22 is rotatably connected to the take-up reel 15. The drive gear 23 is fixed on the support shaft 22 and is arranged in the cavity of the take-up reel 15. A ring rack 24 meshes on the drive gear 23. A ring seat 25 is fixed on the inner side of the ring rack 24. Multiple sets of straightening mechanisms 3 are fixed on the ring seat 25 and are distributed in the circumferential direction of the ring seat 25.
[0028] Please see Figure 4 Each straightening mechanism 3 has a slide rail 31, a knob 32, and a lead screw 33. In specific implementation, multiple slide rails 31 are fixed to the upper end face of the annular seat 25, the knob 32 is installed on the slide rail 31, and the knob 32 is coaxially connected to the lead screw 33. A slider 34 is provided on the lead screw 33, and a positioning post 35 and a straightening roller 36 are fixed on the slider 34. The positioning post 35 and the straightening roller 36 are both vertically arranged. The winding motor 13 can drive multiple positioning posts 35 to rotate, thereby winding the steel bar into a coil. By rotating the knob 32, the lead screw 33 can be driven to rotate, thereby changing the position of the slider 34 and the positioning post 35 on it, thus limiting the inner diameter value of the steel bar. The inner diameter of the steel bar coil can be controlled according to actual needs, meeting the needs of the actual production process. The roller on the straightening roller 36 is set at the end away from the central support shaft 14, so that the straightening roller 36 can contact the steel bar coil, and the position of the steel bar coil is corrected by the rotation of multiple straightening rollers 36.
[0029] Please see Figures 5 to 6 The bottom surface of the winding reel 15 cavity is provided with an annular groove 151. Multiple pulleys 26 are fixed at the bottom of the annular seat 25.

The multiple pulleys 26 are all set in the annular groove 151, and the multiple pulleys 26 are all in contact with the bottom surface of the annular groove 151, so that the multiple pulleys 26 can roll smoothly in the annular groove 151.
[0030] Working principle: Please refer to the following again. Figures 1 to 6In this invention, one end of the reinforcing bar is fed into the cavity of the winding reel 15. The winding motor 13 is driven to run, and the synchronous pulley set drives the central support shaft 14 and the winding reel 15 to rotate. Under the action of multiple positioning posts 35, the reinforcing bar is wound into a coil. The final formed reinforcing bar coil is located outside the multiple positioning posts 35. At the same time, the reinforcing bar coil is also in contact with the cylinder of multiple straightening rollers 36. After that, the winding motor 13 stops running, and the rotary motor 21 is driven to run, driving the support shaft 22, the drive gear 23, the ring rack 24 and the ring seat 25 to rotate. The ring seat 25 drives the multiple straightening rollers 36 to rotate at a uniform and slow speed. By using the rotation of multiple straightening rollers 36 and the positioning of the cylinder on the multiple straightening rollers 36 with the inside of the reinforcing bar, the exposed part of the inside of the reinforcing bar coil can be squeezed back into the inside of the reinforcing bar coil, making the overall reinforcing bar coil more like a ring. This makes the overall shape of the reinforcing bar coil more regular and beautiful, and reduces the overall footprint of the reinforcing bar coil, making it easier to lift and transport.
