[0002] In the grain packaging industry, rice brick packaging machines are widely used because they can achieve vacuum compression packaging of rice, effectively extend the shelf life, and save storage and transportation space. However, there are still many deficiencies in the structural design of existing rice brick packaging machines. In the bag transfer link, some equipment uses simple robotic arms or conveyor belts for bag handling, lacking precise adsorption and positioning components. Bags are prone to shift and fall during the transfer process, resulting in the interruption of the packaging process. Moreover, the processing flow of existing packaging machines is relatively cumbersome, so improvement is needed. Summary of the Invention

A feeding pipe is fixedly connected to the upper side of the frame. The bottom end of the feeding pipe is fixedly connected to a blanking frame. A feeding assembly is arranged below the blanking frame. A working plate is fixedly connected to one side of the frame. A second cylinder is fixedly connected to the frame on one side of the working plate. The top end of the second cylinder is fixedly connected to a storage lifting plate. A waste placement plate is fixedly connected to the frame on one side of the storage lifting plate. A bag transfer mechanism is arranged on the frame near the working plate.

The bag transfer mechanism includes a flipping assembly arranged on one side of the working plate. An adsorption end is arranged on one side of the flipping assembly, and a supporting end is arranged on the other side of the flipping assembly.

[0005] As a preferred technical solution, the adsorption assembly includes a first cylinder arranged on one side of the bag transfer mechanism. The output end of the first cylinder is fixedly connected to a vacuum pump. The suction end of the vacuum pump is fixedly connected to a vacuum suction cup.
