Description

Pallet packaging device with anti-freezing packaging function and anti-freezing packaging method thereof

The invention relates to a pallet, in particular to a pallet packaging device with anti-freezing packaging function and a frost-resistant packaging method thereof.

The rail transport is carried by the pallet as the transportation center. In winter, the temperature in the wilderness reaches almost 40 °C, especially in the desert, Central Asia, Siberia, etc., 40 °C Celsius damages the electronic chip of the liquid crystal display, affecting Liquid crystal display and reliability of various electronic products. Therefore, the anti-freeze packaging of winter railway pallet goods becomes an important solution.

In view of the above, the present invention provides a pallet packaging device having a freeze-proof packaging function, comprising: a pallet body comprising a body portion and a plurality of legs, the body portion having opposite first and second faces, and first The surface forms a plurality of accommodating grooves, and the plurality of legs are connected to the second surface; a plurality of anti-freeze packaging bags, a part of the plurality of anti-freezing packaging bags are located in the plurality of accommodating grooves; the carrying unit is located at the first side, and carries the goods on the carrying unit At the time, the plurality of anti-freeze packaging bags not disposed in the receiving groove cover the goods, wherein the surface of the untouched load bearing unit is covered by the plurality of anti-freezing packaging bags.

The invention also provides a freeze-resistant packaging method, comprising: providing a pallet main body, the pallet main body comprises a plurality of accommodating grooves, and a plurality of anti-freezing packaging bags are arranged in the plurality of accommodating grooves; placing the carrying unit on the main body of the pallet; fixing the goods On the carrying unit; the plurality of anti-freeze packaging bags cover the surface of the cargo without contacting the carrying unit; the fixed goods are integrated with the plurality of anti-freezing packaging bags.

During the day and night, the temperature difference will circulate. When the temperature drops, the anti-freeze bag will absorb the coldness, and the temperature inside will be delayed compared with the external temperature. When the environment is extremely cold, the temperature inside the anti-freeze bag has not dropped to the extremely cold temperature. When the temperature is too cold, the temperature will turn upwards, which will make the anti-freeze package. The bag is affected by the outside air temperature and the temperature rises with the steering. Therefore, the temperature of the goods on the pallet does not reach the extremely cold temperature and starts to reverse, which can effectively prevent the goods from being damaged in the extremely cold area due to the low temperature.
