Description

Prevent that tubular packing carton shakes novel cross cutting base plate that lid destroys a warpage and drops

Technical Field

The utility model relates to a preparation technical field of carton, concretely relates to novel cross cutting bottom version.

Background

The die cutting processing technology is suitable for surface processing of various printed matters, particularly for finishing processing of the surfaces of various grades of cartons, trademarks, artworks and the like, and is also one of important means for realizing packaging design.

The existing die cutting plate generally comprises a knife template and a bottom die template, wherein the knife template comprises a base, and a steel knife, a steel wire and a semi-through knife are arranged on the base; the bottom template comprises crease lines corresponding to the steel wires. Wherein, the steel knife is used for cutting the shape of the paper box; the steel wire and the indentation groove line are matched and used for enabling the paperboard to deform along the steel wire to form a folding line; the semi-through knife is used for forming a semi-through tangent line which does not penetrate through the carton on the paperboard, and the semi-through tangent line is easier to bend the carton.

The specific process is as follows: when die cutting is carried out, the position of the bottom die plate is fixed, the paper board is arranged on the surface of the bottom die plate in an upward mode, the cutter die plate moves downwards, the steel knife on the cutter die plate cuts the paper board into a paper box shape, the steel wire on the cutter die plate and the indentation groove strips on the bottom die plate act together to form an easy folding line, and the cutter die plate cuts a semi-through cutter line on the front side of the paper board. Due to the limitation of the hardness of the used materials, the bottom die plate can deform after batch production, so that the indentation groove of the packaging box has insufficient stiffness and is not fully formed, and the final forming of the packaging box is influenced; errors exist in the plate mounting precision; the plate mounting efficiency is low; because a certain height difference exists at the cutting position of the indentation groove of the bottom template, the die cutting precision is influenced; particularly, the common tubular packing box is mostly used for the top cover part of the toothpaste packing box, so that the influence is great; in the normal technology, need to set up the square destruction mouth of being convenient for paste and opening on the rocking cover of its two sides, destroy four straight flanges of mouth through half wearing sword cross cutting, form half adhesion state, lid after the shaping with rock the lid and destroy the mouth and pass through glue bonding, when opening, after lifting the lid, under the glue effect, destroy the mouth and follow the lid action, half adhesion state is destroyed to break away from rocking the lid, need not to accomplish the action of uncapping with very big strength.

However, in the actual production process, because the notch position of one straight edge of the damaged opening is too close to the cover-shaking indentation groove in the existing die-cutting bottom plate, when die-cutting is carried out, the paperboard is pressed into the indentation groove by the steel wire at the position, the straight edge of the damaged opening is cut by the semi-through cutter adjacent to the paperboard, because the two are close, when the steel wire carries out indentation groove, the adjacent paperboard is pressed upwards to be tilted, and simultaneously the semi-through cutter carries out downward cutting on the tilted paperboard, the cutting stroke is larger than that of a normal cutting part, and the acting force of upward deformation of the paperboard is added, the two factors are superposed, so that the tangent line which is supposed to be semi-through is completely cut, the damaged opening of the final product is warped upwards or downwards, the damaged opening of the final product can be mutually entangled in the paperboard conveying process to influence paper feeding and alignment, and after the final pasting and forming, although the box cover and the cover-shaking cover are adhered together, but the straight edge of the damaged opening is separated from the rocking cover, so that the top cover of the packing box cannot be kept flat, and the product quality is influenced.
