Method for adjusting shape regularity of medicine packaging boxes

Abstract

The invention relates to a method for adjusting shape regularity of medicine packaging boxes. The method includes: under the premise that paper is not exploded during the die cutting and creasing process of the medicine packaging boxes, (1), narrowing creasing, to be more specific, selecting a pointed-end steel wire 0.71mm in thickness as a die cutting steel wire, and allowing the creasing width B to be equal to 1.5c+d-N, wherein c is the thickness of paper, d is the thickness of the die cutting steel wire, and N is 0.05-0.06m; (2), deepening the creasing, to be more specific, customizing the die cutting steel wire matched with a die cutting cutter wire, and allowing the height Xh of the die cutting steel wire to be equal to Dh-c+0.05, wherein Dh is the height of the die cutting cutter wire. By the method convenient for large-scale popularization and application, the shape regularity of the medicine packaging boxes can be increased, the shutdown rate of a high-speed mechanical medicine packaging line is effectively controlled within 1/10000, and production efficiency of clients is guaranteed and client orders are increased evidently while cost of medicine packaging box manufacturers is lowered effectively.

Description

technical field [0001] The invention relates to a method for adjusting the shape circumference of a medicine packaging box, which is mainly used for the post-press processing of the medicine packaging box. Background technique [0002] According to incomplete statistics from the State Food and Drug Administration, the national pharmaceutical industry's automatic drug filling production line (machine-loaded line) has increased by 31.2% compared with the same period last year, and the degree of automation has improved significantly. Pharmaceutical companies have changed their inspection standards for packaging boxes, focusing on printing colors. The requirements in terms of aspects have shifted to the functional requirements for drug packaging boxes, that is, the packaging boxes must be able to adapt to the premise of automatic drug filling production lines. [0003] At present, although the packaging boxes produced by general companies can meet the needs of most customers, on...

Problems solved by technology

[0005] In the die-cutting process, different paper types usually follow the formula B=1.5c+d (where B is the indentation width, c is the thickness of the paper, and d is the thickness of the die-cutting steel wire, which is used in the die-cutting process of pharmaceutical packaging boxes. The thickness of the die-cut steel wire is a fixed value of 0.71mm) to determine the indentation width, but in the actual operation process, the theoretical indentation width obtained according to the above formula is too wide, and the folding line is prone to deviation during the box-gluing process , causing the box shape to be irregular

[0006] The height of the die-cut steel wire is also according to the formula X h =D h -c (where X h is the height of die-cut steel wire, D h is the height of the die-cutting knife line, the height D of the die-cutting knife line used in the die-cutting process of the drug packaging box h is a fixed value of 23.8mm, c is the thickness of the paper), but in the actual operation process, the theoretical die-cutting steel wire height value obtained according to this formula is too small. Relatively speaking, the die-cutting knife line is too high, and the During the cutting process, the height of the die-cutting knife line and the die-cutting steel wire do not match, so that the indentation is too shallow, the indentation is not full, and the resilience increases when the box is folded, causing the box shape to be irregular.

[0007] At present, the commonly used die-cut steel wire is single-ended steel wire or double-ended steel wire, which is also prone to the problem of wide indentation and incomplete indentation.

[0008] In addition to the above, due to the current materials used to make the indentation strips, the indentation is not pressure-resistant, and will change slightly after a period of pressure, which will also cause the indentation to be not full and the box shape to be irregular.
