Background

Various products are transported, stored, stacked, loaded and unloaded through a series of processes from production to use by customers, and all the processes can effectively act on the products in normal environment. In order to prevent the product from being damaged, it is required to reduce the external force and the external environment, and the manufacturing industry generally adds a cushion packaging material in the product packaging box. The cushioning package is a package with certain protection measures taken to relieve the impact and vibration on the contents and protect the contents from damage. Household appliances are obviously protected by the buffer packaging material, and particularly, the refrigerator products are transported in containers for the most part; in a warehouse and transportation, different scenes such as carrying, stacking, loading, unloading and the like exist, and how to make packaging protection of a refrigerator is very important.

In the refrigerator manufacturing industry, in order to protect a refrigerator, a series of packaging materials are required to protect the assembled refrigerator before packaging, and the general process flow is as follows: sleeving a PE protective film cover, sleeving a packaging box, putting 2 front side strips into the packaging box, putting 2 rear side strips into the packaging box, and covering an upper cover plate. The procedure before packaging the refrigerator is at least 5 procedures, and if a front protection plate needs to be added, a procedure is added; meanwhile, as the height of the refrigerator is generally high, the difficulty of manually placing the side bars is high, and the side bars are all required to be placed on a high platform.
