The laser cutting machine is used to cut a sheet metal material to form a sheet metal material. The bending machine is used to bend the sheet metal material. The conveying device 100 is installed between the laser cutting machine and the bending machine, and is used to convey the sheet metal material at the unloading position of the laser cutting machine to the bending machine.

[0031] When the sheet metal processing system in the above embodiment is used, the sheet metal material cut by the laser cutting machine can be unloaded onto the conveying device 100, and then transported to the loading position of the bending machine through the conveying device 100, thereby shortening the sheet metal processing process time, reducing the frequency of manual picking, realizing automatic loading of sheet metal materials, and reducing the sheet metal processing cost. In addition, the conveying device 100 is located between the laser cutting machine and the bending machine, which can realize the diversion and transportation of sheet metal materials of multiple specifications and different thicknesses, and can also be used in different places, and can even work in harsh environments such as high temperature or dust, thereby improving the practicality of the sheet metal processing system.

[0032] The laser cutting machine can be set as any laser cutting device used for cutting sheet metal in the prior art. The bending machine can be set as any bending device used for bending sheet metal in the prior art.

[0033] The conveying direction of the conveying device 100 may be a horizontal direction or an inclined direction.

[0034] As shown in FIG1 , further, the conveying device 100 includes an adjustment mechanism 110 and a conveying mechanism 120 for conveying sheet metal materials, the conveying mechanism 120 is installed on the adjustment mechanism 110, and the adjustment mechanism 110 is used to adjust the height and inclination angle of the conveying mechanism 120. In this way, the conveying mechanism 120 has a feed end and a discharge end, and the height positions of the feed end and the discharge end are adjustable, ensuring that the feed end can be applied to laser cutting machines with different discharge heights, and ensuring that the discharge end can be applied to bending machines with different feed heights, so that the flexibility of the conveying device 100 is increased, and the practicality of the sheet metal processing system is improved.

In this way, the height and tilt angle of the conveying mechanism 120 on the mounting frame 113 can be adjusted by adjusting the position of the channel steel leg 111 relative to the foot cup 112, thereby improving the convenience of adjusting the conveying device 100.

[0036] The channel steel leg 111 can be movably connected with the foot cup 112 in a vertical direction, or movably connected with the foot cup 112 in an arc direction. The channel steel leg 111 can be fixedly connected with the mounting frame 113, or rotatably connected with the mounting frame 113.

[0037] The mounting frame 113 can be formed by assembling and welding angle steels. Specifically in this embodiment, the mounting frame 113 is entirely formed by assembling and welding 128mm*80mm*8.0mm thickened high-quality angle steels.

In this way, the driving sprocket 122 can be accurately installed on the output shaft 1211 and locked with the output shaft 1211 as a whole, thereby improving the reliability of the conveying device 100.

[0049] The locking member may be a latch, a screw or other locking structures. The number of the locking members may be flexibly adjusted according to actual use requirements.

[0050] The limit key 1212 can be integrally formed with the output shaft 1211 and also fixed on the outer wall of the output shaft 1211 by embedding or the like. The limit groove 1223 penetrates the mounting cylinder 1221 along the axial direction of the driving sprocket 122 .

[0051] Specifically in this embodiment, the material of the active sprocket 122 is preferably 45# (surface treated to be black) high rigidity material to ensure the impact accuracy of its roller 124 during the mechanical transmission process. The roller 124 is thickened, thickened and encrypted, and its bearing capacity is good. The scheme in the above embodiment can ensure the rigid rotation of the reduction motor 121 while ensuring the normal operation of the roller 124 and the belt 125, solve the problem of wear of the roller 124, extend the transmission stability and service life of the roller 124, and improve the reliability of the conveying device 100.

In order to ensure that the output shaft 1211 and the driving sprocket 122 are concentrically positioned, the limit key 1212 must be in place and the top screw must be locked.

[0054] The mounting cylinder 1221 can be integrally formed with the outer tooth portion 1222. The outer tooth portion 1222 is located at one end of the mounting cylinder 1221.
