Description

[Technical Field]

[0001] This invention relates to the field of food production equipment technology, and in particular to an automatic material frame transfer device and transfer method. [Background Technology]

[0002] In some food production processes, material crates are used to receive materials, and the crates filled with food are stored in a warehouse for subsequent packaging and sales. For example, in some tea production lines, after the tea leaves are packaged according to the required weight per brew, material crates are used to receive the tea bags, and the crates and tea bags are transported together to the warehouse for storage. Once all the tea bags in the crates have been removed, the empty crates are sent back to the production line to receive more tea, thus achieving the recycling of the material crates.

[0003] Currently, in actual production processes, material frames are typically handled manually. While auxiliary tools, such as handcarts, are used to reduce worker fatigue and improve efficiency, the need for manual handling throughout the entire production process makes it difficult to effectively reduce worker fatigue and improve production efficiency. In view of these problems, the inventors conducted in-depth research, leading to this invention. [Summary of the Invention]
