Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard processing equipment, in particular to an adjustable cardboard creasing device for producing corrugated cardboard. Background Art

[0002] In the production process of corrugated cardboard, creasing is a crucial link, which directly affects the forming effect and final performance of the cardboard. However, the traditional corrugated cardboard creasing equipment has some obvious limitations in design and use, especially in the adjustment of creasing depth.

[0003] Traditional creasing equipment usually uses a fixed-structure creasing mold, which means that the depth of the creasing is pre-set and cannot be adjusted. This design often cannot provide ideal creasing effects when facing cardboards of different materials and thicknesses. If the cardboard is thicker or the material is harder, the creasing may not be clear enough; conversely, if the cardboard is thinner or the material is softer, the creasing may be too deep, causing the cardboard to break or deform.

[0004] In addition, due to the diversity of market demand, different customers or different application scenarios have different requirements for the indentation depth of corrugated cardboard. Traditional indentation equipment cannot be adjusted in real time according to actual needs, which undoubtedly limits its adaptability and flexibility.

However, this method is not only cumbersome and inefficient, but also increases production costs and maintenance difficulties. At the same time, frequent mold replacement may also affect the stability and safety of the production line. Utility Model Content
