[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Reference Figure 1 The utility model provides an automatic feeding device for a shearing machine, including a frame 1, on which a feeding mechanism 2, a roller group 3 and a feeding manipulator 4 are installed, the feeding manipulator 4 is installed above the roller group 3, a dividing mechanism 7 is installed above the feeding mechanism 2, a pressure plate roller 5 is installed on the frame 1 between the feeding mechanism 2 and the roller group 3, and a feeding mechanism 6 is arranged below the roller group 3.

[0019] Reference Figure 2 The material dividing mechanism 7 includes a material dividing slide bar 701, a material dividing motor (not shown) and a material dividing synchronous belt 708 installed on the frame 1. Two material dividing brackets 702 are symmetrically slidably installed on the material dividing slide bar 701. A pushing mechanism 8 is provided in the middle of the material dividing slide bar 701. The material dividing synchronous belt 708 is parallel to the material dividing slide bar 701, and its two sides are respectively connected to the two material dividing brackets 702. The material dividing motor drives the material dividing synchronous belt 708 to rotate, thereby driving the two material dividing brackets 702 to move closer to and away from each other.

[0020] The upper end of the material distribution bracket 702 is hinged with a material distribution cylinder 703, and the lower part is hinged with an L-shaped support arm 704 and an L-shaped material distribution plate 706. The middle part of the L-shaped support arm 704 is hinged with the material distribution bracket 702, one end of the L-shaped support arm 704 is hinged with the piston rod of the material distribution cylinder 703, and the other end is hinged with a connecting rod 705. The middle part of the L-shaped material distribution plate 706 is hinged with the material distribution bracket 702, and the upper part is hinged with the connecting rod 705.

[0021] During operation, the loading mechanism 2 lifts the stacked plates thereon, and the material dividing motor drives the two material dividing brackets 702 to approach each other through the material dividing synchronous belt 708. When the lower end of the L-shaped material dividing plate 706 contacts the gap between the two uppermost plates, the material dividing cylinder 703 pushes the L-shaped material dividing plate 706 to rotate through the L-shaped support arm 704 and the connecting rod 705 to lift the uppermost plate. At the same time, the two material dividing brackets 702 continue to approach to lift the plate and contact it with the pushing mechanism 8. The pushing mechanism 8 pushes the plate toward the pressure plate roller 5. After being leveled by the pressure plate roller 5, the plate moves to the roller shaft group 3.

[0022] Reference Figure 3 The feeding mechanism 6 includes a feeding slide bar 601, a feeding motor (not shown) and a feeding timing belt 602 arranged on the frame 1. Two symmetrical feeding support plates 603 are slidably installed on the feeding slide bar 601. The feeding timing belt 602 is parallel to the feeding slide bar 601, and its two sides are respectively connected to the feeding support plates 603. The feeding motor drives the feeding timing belt 602 to rotate, thereby driving the two feeding support plates 603 to approach and move away from each other.

The pushing motor 802 on the material dividing mechanism 7 is installed on the lower surface of the pushing support plate 801, and the pushing motor 802 on the feeding mechanism 6 is arranged on the upper surface of the pushing support plate 801.

[0025] During operation, after the plate enters the roller group 3, the feeding motor drives the two feeding support plates 603 to approach each other. Since the lower end of the Z-shaped pressure plate 608 is folded upward, the edge of the plate slides to the bottom of the Z-shaped pressure plate 608, and the plate is pressed against the roller group 3 by the spring 607, so that it is in good contact with the pushing wheel 803. After the pushing motor 802 is started, the plate slides into the shearing machine for processing. After the processing is completed, the feeding support plates 603 move to both sides and are grabbed and transported by the unloading robot 4. In actual applications, the unloading robot 4 is composed of a two-axis truss robot with a magnetic suction or vacuum gripper.
