Preparation method of self-clinching-bottom paper box

Abstract

The invention relates to a paper box and particularly relates to a preparation method of a self-clinching-bottom paper box. The preparation method comprises the following steps of: 1) selecting a piece of laminate for later use; 2) sawing the selected laminate to be one plate which is 100mm longer and 100mm wider than the expanded sizes of a product to be produced, for later user, by using a grooving machine; 3) controlling included angles between line AB and line BC, and between line A'B' and line B'C' to be 41-49 degrees, on the middle part of the prepared laminate according to the technique requirement, controlling the included angles between line DC and line DE, and between line D'C' and line D'E' to be 76-85 degrees; D, setting both line DE and line D'E' to be equal to 6mm; 4) grooving; 5) arranging a knife line, an impression line and a tooth-mark line on corresponding positions in the sawn grooves according to the technique requirement; 6) bonding an elastic sponge strip on the place where is 1mm far away from the knife line and the tooth-mark line; 7) mounting a die-cutting plate; 8) mounting and manufacturing an impression base film; 9) arranging a blank die-cutting base steel plate on a die-cutting machine base, cleaning, pushing in the machine and locking; 10) inching the machine; 11) performing pad pressure treatment; 12) die-cutting the box blank; 13) hooking the bottom; 14) folding a main body; and 15) laminating.

Description

technical field [0001] The invention relates to a carton, in particular to a preparation method of a self-closing bottom carton. Background technique [0002] The preparation methods of self-locking bottom cartons at home and abroad are mainly: the size of the lock is relatively random; the angle of the lock is 90 degrees; The angle is 45 degrees; the defects of the carton prepared according to this preparation method are as follows: [0003] 1. Not easy to open; [0004] 2. The bottom of the box cannot be buckled; [0005] 3. The angle of the lock is 90 degrees, the lock cannot be locked, and the lock is easy to open after the goods are loaded, and the items fall out; [0006] 4. The angle between the crease line BC on the glued surface and the indentation line AB on the bottom edge of the surface connected by the crease line and the indentation from the crease line B'C' to the bottom edge of the surface connected by the crease line The included angle of the line A'B' i...

Problems solved by technology

[0005] 3. The angle of the lock is 90 degrees, the lock cannot be locked, and the lock is easy to open after the goods are loaded, and the items fall out;

[0006] 4. The angle between the crease line BC on the glued surface and the indentation line AB on the bottom edge of the surface connected by the crease line and the indentation from the crease line B'C' to the bottom edge of the surface connected by the crease line The included angle of the line A'B' is 45°; the forming effect is poor, and the box is easy to be pulled out of shape, and in serious cases, the box may even be torn, torn or broken along the tooth mark lines BC and B'C' on the glued surface. Tear off the angle ∠β and ∠β′ facing the tooth mark line on the adhesive surface
