[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-4 As shown, in this embodiment, a feeding mechanism of a bending device includes a mounting frame 1, a rotating shaft 2 is rotatably connected inside the mounting frame 1 and near the bottom end, a shaped wheel 3 is fixedly connected to the outer surface of the rotating shaft 2, a material storage platform 25 is fixedly connected to the top of the mounting frame 1, a material pushing through hole 4 is opened through the top of the material storage platform 25, an adjusting frame 5 is fixedly connected to the bottom end of the material storage platform 25 and located at the position of the material pushing through hole 4, a pushing block 6 is slidably arranged inside the adjusting frame 5, a connecting rod 7 is rotatably connected to the pushing block 6, and the other end of the connecting rod 7 is connected to the material storage The bottom end of the platform 25 is rotatably connected, and one side of the connecting rod 7 is rotatably connected to a roller 8, and the outer surface of the roller 8 is tightly fitted with the outer surface of the special-shaped wheel 3. One end of the rotating shaft 2 passes through the inner side wall of the mounting frame 1 and is transmission-connected to a reduction motor 22, and the outer surface of the reduction motor 22 is fixedly connected to one side of the mounting frame 1. Among them, by setting the special-shaped wheel 3, the connecting rod 7 can be driven to swing back and forth through its shape. By setting the adjustment frame 5, it is used to limit the push block 6. By setting the roller 8, the connecting rod 7 can be driven to swing and the friction can be reduced.

[0022] like Figure 1-3 As shown, a driven wheel 10 is fixedly connected to the other end of the rotating shaft 2, and square through holes 12 are opened on both sides of the mounting frame 1. Two square through holes 12 are rotatably provided with two feeding rollers 13, and one end of one of the feeding rollers 13 is fixedly connected to a driving wheel 21, and a transmission belt 11 is transmission-connected to the outer surface of the driving wheel 21, and the inner surface of the transmission belt 11 is transmission-connected to the outer surface of the driven wheel 10. By setting the driven wheel 10, the driving wheel 21 can be driven to rotate. The diameter of the driven wheel 10 is larger than that of the driving wheel 21, so that the driving wheel 21 can rotate faster.

[0023] like Figure 1-3As shown, the top surfaces of both ends of one of the feed rollers 13 are fixedly connected with pressure springs 14, and two adjusting bolts 15 are threadedly connected to the top of the mounting frame 1. The bottom ends of the two adjusting bolts 15 are rotatably connected to the top ends of the two pressure springs 14 respectively. By setting the pressure springs 14, the friction between the feed roller 13 and the steel plate can be increased, thereby making it more convenient to drag the steel plate to move.

The outer surfaces of the two limiting blocks 23 are slidably connected to the inside of the two limiting grooves 24 respectively. By setting the limiting grooves 24 and the limiting blocks 23, the push block 6 can be limited to prevent it from falling off.

[0028] The utility model provides a feeding mechanism for a bending device, and the specific working principle is as follows:

[0029] The staff stacks the steel plates on the storage table 25, and then starts the reduction motor 22. The reduction motor 22 drives the rotating shaft 2 to rotate, so that the special-shaped wheel 3 rotates with the rotating shaft 2. Under the pulling force of the return spring 9, the roller 8 rolls along the surface of the special-shaped wheel 3 and drives the connecting rod 7 to swing, so that the push block 6 slides in the adjustment frame 5 driven by the connecting rod 7, and the bottom layer of steel plates stacked on the storage table 25 are pushed out. In the process of pushing out the steel plates, the rotating shaft 2 rotates to drive the driven wheel 10 to rotate, and the driven wheel 10 drives the driving wheel 21 to rotate through the transmission belt 11, so that the feeding roller 13 rotates, and the steel plates are quickly pushed to move with the cooperation of the two feeding rollers 13 to load the steel plates.
