Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, and in particular to a packaging carton bending device. Background Technology

[0002] Packaging carton bending equipment refers to equipment used to bend cardboard into the shape of a carton. This equipment is widely used in the carton manufacturing process, especially in situations where precise bending and shaping are required. This equipment can effectively solve the problem of soft cardboard that is easy to return to its original shape after bending, ensuring that the shape and size of the carton meet the requirements.

[0003] Traditional cardboard bending equipment is prone to cardboard displacement or springback during the bending process, resulting in bending angle deviation or unclear creases, which affects the structural stability and appearance consistency of the cardboard. In addition, uneven parts are likely to appear on the cardboard surface. Uneven cardboard surfaces will exacerbate the deviation of the bending line, forming a "scissor difference". Frequent manual adjustment of the cardboard position is required to compensate for the equipment defects, increasing the number of operation steps and time costs. Utility Model Content
