Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a three-dimensional storage rack for paper corner protectors. Background Technology

[0002] As a key piece of equipment in modern warehousing, automated storage racks can fully utilize vertical space and effectively increase storage capacity. In the storage of paper corner protectors, their rational structural design ensures orderly storage, preventing deformation and damage caused by haphazard stacking. This provides excellent protection for the paper corner protectors, helping to maintain their shape and performance, and ensuring they can function properly for reinforcement and protection in subsequent packaging applications.

[0003] However, existing three-dimensional storage racks for paper corner protectors have relatively insufficient storage adjustment and adaptability when stacking and storing paper corner protectors. When the stacking amount of paper corner protectors changes, the storage rack cannot adjust the clamping force and height in a timely and effective manner, causing the paper corner protectors to easily shake or slip during storage. The poor adaptability of clamping and adjusting the paper corner protectors seriously affects the stability and safety of paper corner protector storage. The internal space planning of this type of storage rack is unreasonable, the space is relatively small, and the stretching and retrieval capacity is limited. It cannot conveniently simulate the drawer-type storage and retrieval mode, which greatly reduces the convenience of storing and retrieving paper corner protectors and brings many inconveniences to actual use, making it difficult to meet the needs of efficient and convenient warehousing. Therefore, we propose a three-dimensional storage rack for paper corner protectors to solve the above problems. Utility Model Content
