[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] As Figures 1-6As shown in the figure, the present invention provides a technical solution: an industrial hardware bar supply device, which includes a bar body 1 and a conveying mechanism 2. The outer surface of the bar body 1 is slidably connected to the inner wall of the conveying mechanism 2. The conveying mechanism 2 includes a positioning ring 21. One side of the positioning ring 21 is fixedly connected with a plurality of brackets 22. One side of the brackets 22 is fixedly connected with an annular frame 23. The outer surface of the annular frame 23 is fixedly connected with four first support plates 24. The outer surface of the annular frame 23 is fixedly connected with four second support plates 25. A fixed pipe 26 is fixedly connected between one side of the first support plate 24 and the second support plate 25. A rotating plate 27 is rotatably arranged on one side of the fixed pipe 26. A roller 28 is rotatably connected between one side of the rotating plate 27. The outer surface of the annular frame 23 is fixedly connected with four fixing plates 212. A connecting plate 217 is rotatably arranged on one side of the fixing plate 212. A rotating rod 222 is rotatably connected between one side of the connecting plate 217. Two limiting wheels 221 are rotatably connected to the outer surface of the rotating rod 222.

[0020] In this embodiment, the bar body 1 can be positioned through the positioning ring 21 and the annular frame 23, so that the bar body 1 can be transported quickly and accurately through the conveying mechanism 2. At the same time, since the two rollers 28 are symmetric and the two rollers 28 clamp the bar body 1 together, the bar body 1 can be limited for the first time. Then, since the two groups of limiting wheels 221 are symmetric and the two groups of limiting wheels 221 clamp the bar body 1 for secondary limiting, the bar body 1 can be clamped well, preventing the bar body 1 from shifting during movement and enabling accurate fixed-point transmission. At the same time, since the limiting wheels 221 and the rollers 28 can rotate, the bar body 1 will not be worn to a large extent during transportation. After that, the limiting wheels 221 are driven to rotate by a motor 220. Due to the frictional force between the limiting wheels 221 and the bar body 1, the bar body 1 can be driven to be conveyed when the limiting wheels 221 rotate, thus achieving the conveying effect. Embodiment

[0021] As Figures 1-6 As shown in the figure, a rotating hole 29 is opened on one side of the rotating plate 27. The inner wall of the rotating hole 29 is rotatably connected with a shaft rod 210. One end of the shaft rod 210 is fixedly connected with one side of the first support plate 24; Through the above embodiment, the rotating plate 27 can be rotated through the shaft rod 210, and the rotating plate 27 is limited by the fixed pipe 26, enabling the rotating plate 27 to be more stable during rotation; One side of the rotating plate 27 is fixedly connected with a first torsion spring 211. One end of the first torsion spring 211 is fixedly connected with one side of the first support plate 24. The outer surface of the first torsion spring 211 is slidably connected with the outer surface of the shaft rod 210. The outer surface of the first torsion spring 211 is slidably connected with the inner wall of the fixed pipe 26; Through the above embodiment, the elastic potential energy given by the first torsion spring 211 can drive the rotating plate 27 to rotate toward the bar body 1, so that the roller 28 can be tightly attached to the outer surface of the bar body 1. At the same time, the diameter of the bar body 1 can be changed at will by the rotation of the rotating plate 27, so that different bar bodies 1 can be clamped and transported, and the first torsion spring 211 can also be protected by the shaft 210 to prevent the first torsion spring 211 from bending. A fixing hole 213 is formed on one side of one of the fixing plates 212, and a fixing shell 214 is fixedly connected to the inner wall of the fixing hole 213, and a rotating rod 216 is rotatably connected to the inner wall of the fixing shell 214, and one end of the rotating rod 216 is rotatably connected to one side of the connecting plate 217; a second torsion spring 215 is slidably connected to the outer surface of the rotating rod 216, and one end of the second torsion spring 215 is fixedly connected to the inner wall of the fixing shell 214, and the other end of the second torsion spring 215 is fixedly connected to one side of the connecting plate 217; Through the above embodiment, the fixing plate 212 is rotatably connected to the connecting plate 217, and the fixing shell 214 can be well fixed to the fixing hole 213. At the same time, the second torsion spring 215 can be protected by the rotating rod 216 to prevent the second torsion spring 215 from bending and being damaged. At the same time, the second torsion spring 215 can give the connecting plate 217 a rotational force toward the rod body 1, so that the connecting plate 217 can drive the limiting wheel 221 to be tightly attached to the rod body 1, so that no matter how the diameter of the rod body 1 changes, the rod body 1 can be clamped and transported; A base 219 is fixedly connected to one side of another fixing plate 212, a motor 220 is fixedly arranged on the top of the base 219, an axial moving rod 218 is fixedly connected to the output end of the motor 220, and one end of the axial moving rod 218 is rotatably connected to one side of the connecting plate 217; Through the above embodiment, the motor 220 can be supported and fixed by the base 219, and the shaft moving rod 218 rotates through a fixing plate 212 and a connecting plate 217 and is rotatably connected to another connecting plate 217; A first gear 223 is fixedly sleeved on the outer surface of the rotating rod 222, a second gear 224 is fixedly sleeved on the outer surface of the axial moving rod 218, a chain 225 is arranged on the outer surface of the first gear 223, and the first gear 223 and the second gear 224 are connected by the chain 225; Through the above embodiment, the first gear 223 and the second gear 224 are driven by the chain 225, and the motor 220 provides power, so as to drive the limiting wheel 221 to rotate, and then drive the rod body 1 to be transported; The roller 28 includes a support rod 281 and a protective wheel 284. A partition plate 282 is fixedly sleeved on the outer surface of the support rod 281. A connecting pipe 283 is fixedly sleeved on the outer surface of the partition plate 282. The inner wall of the protective wheel 284 is slidably connected to the outer surface of the connecting pipe 283. A plurality of limiting holes 285 are provided on the outer surface of the connecting pipe 283. Bolts 286 are provided on the inner walls of the limiting holes 285. The outer surface of the connecting pipe 283 is fixedly connected to the inner wall of the protective wheel 284 through the bolts 286. The limiting wheel 221 includes a wheel core 2211 and a protective sleeve 2213. A convex ring 2212 is fixedly connected to the outer surface of the wheel core 2211. A groove 2214 is formed in the inner wall of the protective sleeve 2213. The inner wall of the groove 2214 is engaged with the outer surface of the convex ring 2212. The outer surface of the wheel core 2211 is slidably connected to the inner wall of the protective sleeve 2213; Through the above embodiments, the protective wheel 284 can protect the bar body 1, preventing scratches on the bar body 1 due to relatively large extrusion strength or scratches on the protective wheel 284. Both the protective wheel 284 and the protective sleeve 2213 are made of rubber and have a certain degree of softness. The support rod 281 can act as a shaft, and the protective wheel 284 can be easily removed through the bolts 286. The design of the convex ring 2212 and the groove 2214 also facilitates the removal and installation of the protective sleeve 2213; Working principle: Such as Figures 1-6As shown in the figure, the bar body 1 is passed through the positioning ring 21 and the annular frame 23. Then, the first torsion spring 211 and the second torsion spring 215 are used to drive the rotating plate 27 and the connecting plate 217 respectively to clamp the bar body 1. The rotating plate 27 can be rotated by the shaft rod 210, and the rotating plate 27 is limited by the fixed tube 26, which can make the rotating plate 27 more stable during rotation. Due to the elastic potential energy given by the first torsion spring 211, the rotating plate 27 can be driven to rotate towards the bar body 1, so that the roller 28 can closely adhere to the outer surface of the bar body 1. At the same time, when the rotating plate 27 rotates, the diameter of the bar body 1 can be changed at will, so that different bar bodies 1 can be clamped and conveyed. Moreover, the shaft rod 210 can also protect the first torsion spring 211 to prevent the first torsion spring 211 from being bent. The fixing plate 212 and the connecting plate 217 are rotatably connected, and the fixing shell 214 can be well fixed with the fixing hole 213. At the same time, the second torsion spring 215 can be protected by the rotating rod 216 to prevent the second torsion spring 215 from being bent and damaged. At the same time, the second torsion spring 215 can give the connecting plate 217 a rotational force towards the bar body 1, so that the connecting plate 217 can drive the limiting wheel 221 to closely adhere to the bar body 1. Thus, no matter how the diameter of the bar body 1 changes, the bar body 1 can be clamped and conveyed. The bar body 1 is clamped by the rollers 28 and the limiting wheels 221 connected to the rotating plate 27 and the connecting plate 217. Then, the motor 220 drives the shaft moving rod 218 to rotate. The rotation of the shaft moving rod 218 drives the second gear 224 to rotate. The second gear 224 drives the first gear 223 to rotate through the chain 225. The rotation of the first gear 223 drives the rotating rod 222 to rotate. The rotation of the rotating rod 222 drives the limiting wheel 221 to rotate. The friction force between the limiting wheel 221 and the bar body 1. When the limiting wheel 221 rotates through this friction force, the limiting wheel 221 can drive the bar body 1 to move. And during the movement of the bar body 1, since the limiting wheel 221 and the roller 28 can rotate, the bar body 1 will not be worn to a large extent during transportation. After that, the motor 220 drives the limiting wheel 221 to rotate. Due to the friction force between the limiting wheel 221 and the bar body 1, when the limiting wheel 221 rotates, it can drive the bar body 1 to be conveyed, thus achieving the conveying effect.
