Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and relates to a control system of a double-bag type fresh grape packaging and grading device. Background Art

[0002] In the grape production cycle, packaging and grading of fresh grapes after picking is one of the important links in the grape production process, which plays an important role in improving the quality of grapes and the economic benefits of the grape industry. Fresh grapes are thin and juicy, and they will be damaged by wear, collision and threshing due to lack of effective protection during the harvesting, packaging and transportation. If not handled in time, the grapes will be infected by bacteria and spoil, causing a lot of economic losses. Packaging fresh grapes can maintain the quality of fresh grapes and extend the shelf life, and can also increase the added value and production value of fresh grapes. At present, the grading and packaging process of fresh grapes is mainly completed manually by experienced workers, which has low production efficiency and high labor consumption.

[0003] Most of the existing fruit and vegetable packaging machines are still in the experimental stage, and the full process automation of packaging machinery has not been realized. Therefore, it is of great significance to study the automatic packaging device for fresh grapes, which can not only reduce the labor input and cost, but also improve the mechanization degree in the field of grape production. Summary of the invention

After the transparent bag is taken out, the transparent bag is sucked by the vacuum suction cup and moved to the bottom of the material dropping device. The transparent bag opening cylinder on the opposite side of the transparent bag is also installed with a suction cup fixing plate A and a vacuum suction cup A. The vacuum suction cup is pressed against the bag opening of the transparent bag through the movement of the cylinder push plate, and then the cylinder push plate is retracted to complete the bag opening action; the transparent bag gripper can grab both sides of the transparent bag after the bag opening action is completed to withstand the impact force generated when the grapes are dropped.

[0025] In the improved solution, four buffer springs of the transparent bag storage box are respectively installed on the bag pushing plate, which can make the transparent bag close to the front plate of the bag storage box body, facilitating the subsequent bag taking action.
