Description

Technical Field

[0001] The utility model relates to the field of piano packaging equipment, in particular to piano production line packaging equipment. Background Art

[0002] As a large and expensive musical instrument, the piano must be protected in sturdy packaging before it is processed and shipped out of the factory, and suitable foam blocks must be installed at the corners of the piano to fully protect the piano during transportation.

[0003] Because the piano itself is very large and heavy, it is inconvenient to carry and pack it manually. Therefore, piano packing now generally adopts the method of mechanical lifting and placing from top to bottom into the packaging box. However, while the piano is being placed in, staff are required to assist in propping up the cardboard at the opening of the packaging box on the ground to ensure that the piano can enter smoothly. With this operation method, the workload of the workers is still large and the packing efficiency is not high.

[0004] Therefore, in view of the fact that the hanging packaging method used for the above-mentioned pianos leaving the factory requires manual assistance to open the packaging boxes, the workers have a heavy workload and the packaging efficiency is low, a more efficient packaging equipment can be designed to replace manual labor by using a mechanism that automatically opens the packaging boxes, thereby eliminating a large amount of labor investment. Utility Model Content
