[0002] In order to facilitate storage and transportation, a packaging machine is needed to pack the wheat seeds into packaging bags. At present, the process is roughly to first place a large number of wheat seeds in the hopper, and then intermittently discharge a certain amount of wheat seeds from the outlet of the hopper, and then use packaging bags to receive them at the outlet of the hopper.
[0003] The existing wheat seed packaging machine does not have a packaging bag clamping device, so it is necessary to manually hold the packaging bag and hold the bag mouth open until the packaging bag is filled with wheat seeds before releasing the packaging bag. The packaging bag also becomes heavier in the process of filling the wheat seeds, which requires a lot of manpower in the production process and increases the production cost.

In short, the utility model can automatically clamp the bag mouth of the packaging bag on the outside of the outlet of the discharge hopper, reduce manpower requirements, and reduce production costs.
[0005] However, the packaging bag clamping mechanism in the above-mentioned patent cannot be adjusted according to the size of the bag opening, and after the bag is full, it is necessary to stop unloading, remove the full packaging bag, and then install the empty packaging bag before it can be used again, resulting in low packaging efficiency.
