Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, and in particular to a detachable corner protector device. Background Technology
[0002] Corner protectors, also known as edge protectors, paper corner protectors, or corner cardboard, are made from yarn tube paper and kraft paper through a specific corner protector machine. This material has smooth and flat ends, no obvious burrs, and is perpendicular to each other, giving it good appearance and structural characteristics. Paper corner protectors can protect the easily damaged edges and corners of products, effectively reducing damage caused by collisions, friction, and other factors during transportation and storage. According to actual usage experience, the practicality of paper corner protectors is comparable to that of wooden crates, and they perform excellently in reducing shipping costs.
[0003] In the factory's production process, paper corner protectors are an important auxiliary material, which are usually stored in corner protector bins for easy access by operators. However, when the paper corner protectors in the bins run out, operators often have to climb to higher places to replenish them. This not only poses a safety hazard, but also has relatively low replenishment efficiency. To solve this problem, it is necessary to design a detachable corner protector bin that can efficiently and safely replenish paper corner protectors. Utility Model Content
