Description
Technical Field
[0001] The utility model belongs to the technical field of post-printing paper product processing, in particular to a double-groove creasing knife. Background Art
[0002] Currently, creasing is a common process in the printing and packaging industry, which forms a groove by applying pressure on paper or cardboard to facilitate folding or bending. Traditional creasing machines use a set of creasing knives with a fixed width to form the indentation. However, this method has some problems.
[0003] First, conventional creasing machines can only form indentations of fixed widths. This means that if the width of the indentation needs to be changed, the indentation knife needs to be replaced. This not only requires the purchase of additional indentation knives, but also requires time and labor to replace the knives. In addition, since a set of knives is required for each indentation width, multiple sets of knives need to be purchased and stored, which increases costs and storage space.
[0004] Secondly, if the thickness of the paper is different, different widths of indentation may be required. For example, thicker paper may require wider indentation to prevent the paper from breaking when folded. However, traditional indentation machines cannot adjust the width of the indentation, so they cannot adapt to different thicknesses of paper.
[0005] In addition, since multiple sets of tools need to be purchased and stored, if a set of tools is not used for a long time, it may be forgotten or lost. This not only wastes resources, but also may cause inconvenience when the tool is needed.
[0006] Through the above analysis, the problems and defects of the prior art are: the indentation width cannot be adjusted, multiple sets of tools need to be purchased and stored, and the tools may be lost. Utility Model Content
[0007] In view of the problems existing in the prior art, the utility model provides a double-groove indentation knife, which can indent two width sizes and effectively solves the problems existing in the prior art.
[0008] The utility model is implemented as follows: a double-groove creasing knife comprises a tool positioning groove, a creasing knife (with a knife tip), a creasing knife groove (wide knife groove, narrow knife groove), a handle fixing thread, a guide shaft, and a return spring;
[0009] The tool positioning grooves are provided on the upper and lower sides of the double-groove creasing knife and are used to fix and position the creasing knife;
[0010] The upper indentation knife (with a knife tip) is arranged below the upper indentation knife and is used to cut into the paper to form an indentation;
[0011] The lower indentation knife (with a wide knife groove and a narrow knife groove), the wide knife groove and the narrow knife groove are arranged above the lower indentation knife, corresponding to the tip of the upper indentation knife, and are used to form indentations of different widths;
