Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a box-folding component of a box-sealing machine. Background Technology

[0002] Currently, in the tobacco industry, when a malfunction occurs on the overhead conveyor line for finished cigarettes, or at the end of the conveyor line where the sealing machine is connected, resulting in a shutdown of more than 30 minutes, the tobacco industry resorts to manually stacking the cigarette cartons into cartons at the packaging machine's exit point. This method ensures efficient production without shutting down the packaging machine. This process involves a significant amount of folding work on the inner and outer layers of the cartons.

[0003] First, manual assistance is required to fold the inner and outer panels of the opened carton in a specific order. Then, the cartons are stacked and placed into the carton. Next, the inner and outer panels of the front of the carton are folded in a similar order before sealing. This manual operation is inefficient and wastes significant manpower and resources. Since a cigarette factory's economic benefits depend on its production volume, production efficiency is crucial. Manual carton packing is technically low-skilled and time-consuming. There is a market demand for an automated carton-sealing machine with folding components to replace the manual folding process and improve production efficiency. Utility Model Content

The box head and the box tail are each provided with box flaps for covering the box body entrance and exit, namely the box head upper page, box head lower page, box head first side page, box head second side page, box tail upper page, box tail lower page, box tail first side page, and box tail second side page.

[0039] The main frame 10 is a sheet metal frame structure composed of several profiles, mainly serving a supporting function and providing an installation base for the various components of the equipment. In this embodiment, a carton rack 12 is provided inside the main frame 10. The carton rack 12 mainly includes several support rods disposed within the main frame 10, providing support for the placement and conveying of cartons. A packing station 11 is formed on the carton rack 12; the packing station 11 is used to place cartons to be folded, and a packing channel 61 is formed at one end of the packing station 11, which is used to load items into the cartons to be folded.

[0040] The box head folding device is located at one end of the packing station 11 and is located near the packing channel 61. It is used to fold the box head and each box leaf of the carton.
