In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a steel bar feeding device, including a bracket 1, an inner cavity of the bracket 1 is provided with a conveying roller 2, one end of the conveying roller 2 is movably connected to the inner wall of the bracket 1 through a bearing, and the conveying roller 2 is used to convey the steel bar. A guide assembly 3 is provided on the top of the bracket 1. The number of the guide assemblies 3 is two groups and they are respectively located at the front end and the rear end of the top of the bracket 1. The guide assembly 3 includes a support plate 301, a limit plate 302, a threaded rod 303 and a knob 304. The guide assembly 3 is used to guide the steel bar. A transmission assembly 4 is provided at the bottom of the bracket 1, and the transmission assembly 4 is used to provide power to the conveying roller 2.

[0023] like Figure 1-4 As shown, the knob 304 is turned, and the knob 304 drives the threaded rod 303 to rotate along the inner cavity of the support plate 301. The threaded rod 303 rotates and pushes the limit plate 302 to move toward the middle. A feeding guide groove is formed between the two limit plates 302, so that the conveying trajectory of the steel bar can be limited, thereby preventing the steel bar from being offset during the conveying process. The transmission component 4 drives the conveying roller 2 to rotate, so that the conveying roller 2 can convey the steel bar. The knob 304 can also use a stepping motor to reduce manual work.

[0024] Example 2

[0025] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the support plate 301 is fixedly connected to the bracket 1 , and the limiting plate 302 is located on the top of the conveying roller 2 and is movably connected to the conveying roller 2 .

[0027] One end of the threaded rod 303 penetrates the support plate 301 and is movably connected to the limit plate 302 through a bearing, and is threadedly connected to the inner cavity of the support plate 301 . The knob 304 is fixedly connected to the other end of the threaded rod 303 .

[0028] The transmission assembly 4 includes a protection plate 401 , a servo motor 402 , a single-row sprocket 403 and a double-row sprocket 404 . The protection plate 401 is fixedly connected to the bracket 1 .

[0029] The double-row sprocket 404 is installed in the inner cavity of the bracket 1 and is movably connected to the inner wall of the bracket 1 through a bearing. The servo motor 402 is fixed to the bottom of the bracket 1.

[0030] The output shaft of the servo motor 402 is connected to the single-row sprocket 403, and the single-row sprocket 403 is connected to the double-row sprocket 404 through a chain transmission. The other end of the conveying roller 2 is fixedly connected to the double-row sprocket 404. There are multiple groups of double-row sprockets 404, and every two double-row sprockets 404 are connected through a chain transmission.

[0031] like Figure 1-4 As shown, by turning the knob 304, the knob 304 drives the threaded rod 303 to rotate along the inner cavity of the support plate 301. While the threaded rod 303 rotates, it pushes the limit plate 302 to move toward the middle. A feeding guide groove is formed between the two limit plates 302, so that the conveying trajectory of the steel bar can be limited. Turning the knob 304 clockwise can make the limit plate 302 move toward the middle, and reversing the rotation makes the limit plate 302 move away from the steel bar. The output shaft of the servo motor 402 rotates to drive the single-row sprocket 403 to rotate. When the single-row sprocket 403 rotates, it drives the servo motor 402 to rotate through the chain. The servo motor 402 is provided with multiple groups, and the servo motors 402 are connected by chain transmission, so that multiple groups of servo motors 402 can rotate at the same time, and then the servo motor 402 can drive the conveying roller 2 to rotate. When the conveying roller 2 rotates, it can convey the steel bar, thereby completing the feeding operation of the steel bar.

[0032] When in use, firstly, the conveying trajectory of the steel bar is limited by the guide assembly 3, and the knob 304 is turned clockwise, and the knob 304 drives the threaded rod 303 to rotate along the inner cavity of the support plate 301. While the threaded rod 303 rotates, the limiting plate 302 is pushed to move toward the middle, and a feeding guide groove is formed between the two limiting plates 302, so as to limit the conveying trajectory of the steel bar, thereby preventing the steel bar from deviating during the conveying process. The output shaft of the servo motor 402 rotates to drive the single-row sprocket 403 to rotate. When the single-row sprocket 403 rotates, the servo motor 402 is driven to rotate by the chain. The servo motor 402 is provided with multiple groups, and the servo motors 402 are connected by chain transmission, so that the servo motor 402 can drive the conveying roller 2 to rotate. When the conveying roller 2 rotates, the steel bar can be conveyed, thereby completing the feeding operation of the steel bar, thereby preventing the steel bar from deviating during the conveying process, and effectively improving the feeding efficiency of the steel bar.
