Abstract
Description
Technical Field
[0001] This application relates to the field of steel bar processing technology, and in particular to a steel bar feeding device. Background Technology
[0002] Small steel balls used in industry are generally made by hot processing of steel bars. The process can be roughly divided into five stages: feeding, heating, cutting, stamping, and cooling. Among them, the feeding stage involves continuously feeding steel bars into an electric heating box for heating to soften the steel bars, making them easier to cut and stamp in the future.
[0003] Traditionally, material feeding relies on workers using lifting equipment. Due to the long length and heavy weight of the steel bars, multiple fixations are required before lifting to ensure safety. The steel bars are then hoisted to the feeding mechanism, which finally transports them into the electric heating box. This method is cumbersome, slow, and prone to material shortages in the heating box, resulting in energy waste. Utility Model Content
[0004] To solve or partially solve the problems existing in the related technologies, this application provides a steel bar feeding device that can automatically feed materials without the need for worker assistance, and can avoid material interruption and ensure the continuity of feeding.
[0005] This application provides a steel bar feeding device, comprising:

[0007] A feeding mechanism, which is mounted on a conveyor frame, is used to convey steel bars to an electric heating box. The conveyor frame is located on the lower side of the inclined bar.
[0008] The feeding mechanism is used to transfer steel bars from the material rack to the feeding mechanism. The feeding mechanism includes a telescopic rod and a feeding rack. The telescopic rod is arranged vertically and the feeding rack is fixedly connected to the end of the telescopic rod. The feeding rack has a U-shaped structure and the bottom of the feeding rack is an inclined surface.

[0031] See Figure 1-3 A steel bar feeding device, comprising:
[0032] The material rack 1 is welded from square steel. An inclined rod 11 is installed at the top of the material rack 1, and steel bars 8 are placed on the inclined rod 11. A limiting block 13 is installed at the lower end of the inclined rod 11 to prevent the steel bars 8 from slipping off the inclined rod 11. Furthermore, the inclination angle of the inclined rod 11 is 3° to 5°. Within this angle range, it ensures that the steel bars 8 will naturally roll to the lower side when placed on the inclined rod 11, while minimizing the impact on the limiting block 13 when the steel bars 8 roll to the end. Furthermore, an alignment plate 12 is fixedly installed on the material rack 1. Since the steel bars 8 are bundled and packaged, they are prone to unevenness during transportation, which can affect the continuity of subsequent material loading. The alignment plate 12 ensures that each steel bar 8 is placed neatly on the material rack 1. Specifically, the bundled steel bars 8 are lifted and transported to the material rack 1 using lifting equipment, and the bundle of steel bars 8 is slowly lowered so that one end is aligned with the alignment plate 12. A worker uses a tool to push the other end of the bundle of steel bars 8 so that each steel bar 8 contacts the alignment plate 12, thus ensuring the neatness of the steel bars 8. After alignment, the binding straps of the steel bars 8 are untied, and the steel bars 8 roll naturally to the lower side of the inclined bar 11 under the action of gravity, and finally stop at the limit block 13. It should be noted that because the surface of the steel bars 8 is smooth, a single worker can push the steel bars 8 to slide along their axial direction.
[0033] A feeding mechanism 3 is mounted on the conveyor frame 2 and is used to transport the steel bars 8 to the electric heating box 7. The conveyor frame 2 is fixedly mounted on the lower side of the inclined rod 11 for easy loading. Multiple feeding mechanisms 3 are evenly arranged on the conveyor frame 2. Each feeding mechanism 3 includes a support 31, a rotating shaft 32, a conveying wheel 33, and a motor 36. The supports 31 are symmetrically fixed to the top of the conveyor frame 2, and a rotating shaft 32 is rotatably mounted between two supports 31. A conveying wheel 33 is fixedly connected to the middle position of the rotating shaft 32. The conveying wheel 33 has a V-groove to ensure the stability of the steel bars 8 placed on the conveying wheel 33. Adjacent rotating shafts 32 are connected by chain drive. The motor 36 can drive all rotating shafts 32 to rotate synchronously, thereby transporting the steel bars 8 to the electric heating box 7. For details on the transmission method, please refer to [link to specific details]. Figure 3A drive sprocket 35 is fixedly connected to the end of the rotating shaft 32. The drive sprockets 35 of adjacent rotating shafts 32 are connected by a chain 34. One of the rotating shafts 32 is chain-driven to the motor 36. When the motor 36 starts, it can drive all the rotating shafts 32 to rotate synchronously.
[0034] The feeding mechanism 4 is used to transfer steel bars 8 from the material rack 1 to the feeding mechanism 3. The feeding mechanism 4 includes a telescopic rod 42 and a feeding rack 43. The telescopic rod 42 is vertically mounted on the base frame 41, which is fixed to the ground. The feeding rack 43 is fixed to the end of the telescopic rod 42. The feeding rack 43 can be raised and lowered by the telescopic rod 42. The telescopic rod 42 can be an electric telescopic rod. See also Figure 4 , Figure 5 The feeding rack 43 has a U-shaped structure and the bottom of the feeding rack 43 is an inclined surface. The side closer to the material rack 1 is higher and the side closer to the feeding mechanism 3 is lower. A baffle 431 for blocking the steel bar 8 is provided on the lower side of the feeding rack 43. A stiffening plate 432 is provided on the side of the baffle 431. The stiffening plate 432 improves the impact resistance of the baffle 431. The inclination angle of the bottom inclined surface of the feeding rack 43 is 3° to 5°. Within this angle range, it can ensure that the steel bar 8 will roll naturally to the lower side when placed on the feeding rack 43, and minimize the impact on the baffle 431 when the steel bar 8 rolls to the end.
[0035] Its specific working process is as follows: See Figure 5 Under normal conditions, the telescopic rod 42 retracts to prevent the feeding rack 43 from contacting the steel bar 8, allowing the steel bar 8 on the feeding rack 1 to roll normally to the limit block 13; see also Figure 4 After the steel bar 8 at the feeding mechanism 3 is fed, the control telescopic rod 42 extends, driving the feeding frame 43 to rise. During the process of the feeding frame 43 rising, it will push up the steel bar 8 that is in contact with the limit block 13, causing it to rise as well. When the bottom height of the feeding frame 43 exceeds the limit block 13, the steel bar 8 will roll naturally to the side of the baffle 431 under the action of gravity and eventually contact the baffle 431. At this time, the telescopic rod 42 shortens, driving the steel bar 8 to fall down and placing the steel bar 8 smoothly on the conveyor wheel 33. The telescopic rod 42 continues to shorten, so that the steel bar 8 completely leaves the feeding frame 43, completing the feeding.
[0036] In some embodiments, a detection sensor 5 corresponding to the steel bar 8 is also installed at the discharge end of the feeding mechanism 3. The detection sensor 5 is a through-beam photoelectric sensor, and it is mounted at the discharge end of the feeding mechanism 3 via a bracket 6. Furthermore, the detection sensor 5 and the telescopic rod 42 can be connected to an external central control system to achieve automatic feeding control. The principle is as follows: when the steel bar 8 is not fully discharged, the beam of the detection sensor 5 is blocked by the steel bar 8, and the system determines that there is an object, waiting for feeding to complete; when the steel bar 8 is fully discharged, the beam of the detection sensor 5 is unobstructed, and the system determines that there is no object, proving that the steel bar 8 has been fed completely. At this time, the telescopic rod 42 is activated to execute the above feeding process. It should be noted that the structure and method of the control circuit are existing technologies and will not be described in detail here.
[0037] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
