[0002] During the canned milk powder production process, a large number of milk powder cans stacked on a milk powder can tray need to be picked up in sequence by a milk powder can grabbing robot and placed in an orderly manner to facilitate the subsequent production and processing of the milk powder. When there are no milk powder cans on the milk powder can tray, the production worker first needs to pause the milk powder can grabbing robot, then enter the milk powder can grabbing robot's operating area and manually move the empty milk powder can tray to the return conveyor line. The empty milk powder can tray can then be transported to the warehouse through the return conveyor line. However, when manually moving the milk powder can tray, the production worker will enter the milk powder can grabbing robot's operating area. If the milk powder can grabbing robot loses control, it will cause harm to the production worker, posing a major safety hazard. In addition, manual handling of the milk powder can tray is inefficient and labor-intensive for the production worker. Summary of the Invention

[0006] As a further definition of the present invention, the movable bracket includes a rectangular frame slidably connected to the upper beam and the lower beam through a pulley mechanism, two horizontal rods relatively fixed on both sides of the bottom end of the rectangular frame, and at least one connecting rod fixed between the two horizontal rods, and a reinforcing diagonal rod is fixed between each horizontal rod and the top of the rectangular frame.

[0007] As another limitation of the present invention, the mechanical claw mechanism includes a mounting plate, four mechanical claws rotatably connected to the four corner positions of the mounting plate, two first cylinders provided on the mounting plate, and two second cylinders provided on the mounting plate; the first piston rod in each first cylinder passes through the mounting plate and is fixedly connected to the movable bracket, and the front end of the cylinder barrel in each first cylinder is fixedly connected to the mounting plate; each second cylinder can drive the two mechanical claws close to it to rotate to achieve clamping of the milk powder can tray.

[0008] As a further limitation of the present invention, the mechanical claw mechanism also includes a plurality of guide rods fixed on the movable bracket, and each guide rod is slidably connected to the mounting plate.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] (1) The mechanical claw mechanism of the utility model can clamp the milk powder tin tray, the driving mechanism can drive the mobile bracket to move, and the movement of the mobile bracket can drive the mechanical claw mechanism to move.
