Automatic plating and packaging device and packaging method for plum fresh-keeping transportation

Abstract

The present invention discloses an automatic tray packaging device and a packaging method for plums for fresh-keeping transportation, and relates to the technical field of fruit packaging. The present invention comprises a working box, a feeding assembly, and a packaging assembly. Plums fall into a collection and packaging box through a guide frame. A rotating movable block drives a tray push plate downward, causing the bottom end of the tray push plate to contact the bottom surface of the inner wall of the collection and packaging box. The rotating movable block drives the tray push plate to move, and the tray push plate pushes the plums toward one end of the collection and packaging box, so that the plums are dispersed in the collection and packaging box. The rotating movable block drives the tray push plate upward, causing the bottom end of the tray push plate to be higher than the top surface of the collection and packaging box. The rotating movable block drives the tray push plate to move back to its original position. This reciprocating process disperses the plums in the collection and packaging box, preventing the plums from piling up in one place and being squeezed and broken during packaging, resulting in waste and reduced packaging effect.

Description

Technical Field

[0001] The present invention belongs to the technical field of fruit packaging, and in particular relates to an automatic plating and packaging device and a packaging method for plums to be transported for fresh preservation. Background Art

[0002] Plums, also known as Jiayingzi and Shanlizi, are the fruit of the Prunus tree in the Rosaceae family. They are grown in most parts of my country. They are plump, round, translucent, and sweet, and can be eaten fresh or preserved. Currently, the market primarily sells fresh plums, but they need to be preserved to facilitate long-distance transportation and sales, greatly expanding the sales range of plums.

[0003] In the existing technology, plums are usually arranged on a plate and packed with plastic wrap for subsequent transportation. During the process of arranging and packing the plums, a conveyor belt transports the plums into a collection box. The plums are easily piled up in the same position, and are squeezed and broken when packed, resulting in waste. Too many plums piled up in one place will cause some plums to overflow from the packing box and roll around. Manual work is required to disperse the plums in the collection box, which is inefficient. After the plums are arranged on the plate, they need to be packed with plastic wrap, and the plums need to be moved from the arranging device to the packing device, which reduces work efficiency. In the process of moving the collection box, plums may also fall from the collection and packing box, reducing the applicability of the device. Summary of the Invention
