Description

Technical Field

[0002] Plums, also known as Jiayingzi, mountain plums, etc., are the fruits of the plum tree of the Rosaceae family. They are produced in most parts of China. They are plump, round, delicate, and sweet in taste. They can be eaten fresh or made into preserved fruits. Currently, fresh plums are mainly sold on the market, but they all need to be preserved to help with long-distance transportation and sales, thus greatly expanding the sales range of plums. In the existing technology, plums are usually arranged on plates and packaged with plastic wrap, and then transported. During the process of arranging and packaging plums, the conveyor belt transports plums into the collection box. The plums are likely to accumulate in the same position, and they are squeezed against each other during packaging, resulting in breakage and waste. Excessive plums accumulating in one place will cause some plums to overflow from the packaging box and roll around everywhere, requiring manual dispersion of the plums in the collection box, with low work efficiency. After the plums are arranged on the plates, they need to be packaged with plastic wrap, and the plums need to be moved from the plate arranging device to the packaging device, reducing work efficiency. During the process of moving the collection box, plums may also fall from the collection and packaging box, reducing the applicability of the device. Summary of the Invention

The moving clamping plate 306 and the lifting clamping plate 307 are arranged at one end of the collecting and packaging box 301; The rotating and moving block 302 can drive the disc pushing plate 303 to move. The disc pushing plate 303 can push the plums in the collecting and packaging box 301; the guiding frame 203 can stop the feeding of plums. The collecting and packaging box 301 can move vertically upward. The rotating and moving block 302 can rotate and then move, so that the fixed clamping plate 304 and the rotating clamping plate 305 clamp the plastic film and move. The moving clamping plate 306 and the lifting clamping plate 307 can clamp the plastic film and can drive the plastic film to move; During use, place the plums on the feeding conveyor belt 201. The feeding conveyor belt 201 transports the plums. The plums pass through the screening baffle 202, separating the large-sized plums from the small-sized plums. The large-sized plums and the small-sized plums respectively enter the guiding frame 203. The guiding frame 203 guides the large-sized plums and the small-sized plums into different packaging assemblies 3 respectively, screening the plums, separating the plums with large size differences, and improving the packaging efficiency; The plums fall into the collecting and packaging box 301 through the guiding frame 203.
