Description

Technical Field

[0001] This utility model belongs to the technical field of automated production equipment for packaging products, and in particular relates to a device and system for opening cartons. Background Technology

[0002] Cardboard boxes are widely used in daily logistics and packaging due to their lightweight, environmental friendliness, and cost-effectiveness. They are not only easy to carry and store, but also environmentally friendly, while reducing packaging costs for businesses. However, to save space and facilitate storage, these boxes are usually folded flat when not in use. When needed, they must be manually unfolded and folded into the appropriate shape, a process that is time-consuming, labor-intensive, and inefficient. The limitations of manual operation are particularly evident when facing large packaging demands, as the manual unpacking process consumes significant time and manpower, increasing operating costs and potentially reducing packaging efficiency. To address this issue and improve packaging efficiency while reducing labor costs, the application of automation technology becomes crucial. However, during automatic unpacking, the upright or inward-tilted top of the box after automatic opening and folding is detrimental to the subsequent automatic packing process. To further improve packaging line efficiency, a device is needed to open the box top outward and transport it to the appropriate position for convenient automatic packing, as well as an automated unpacking system that facilitates packing.
