Description

Carton making method and carton thereof

This creation belongs to the field of carton making technology, especially a carton making method and a carton thereof that can be positioned and cut to reduce the defect rate.

With the advancement of carton manufacturing technology and printing technology, as well as the awareness of environmental protection, in recent years, more and more applications of carton as packaging products, including: food, small items or various 3C electronic products, are not only widely used. And can be quickly customized to meet the needs of customers, so it can be said that it is a very popular packaging method.

The carton for packaging 3C electronic products pays more attention to the quality of the folded, especially the verticality between adjacent two sides and the sharpness at the adjacent corners to obtain a better appearance. To this end, manufacturers have developed a method for the manufacture of such a special packaging carton, which uses cardboard as a substrate, and first forms a groove in the shape of a well on the cardboard by means of a trench. Forming an outer contour of the paper box by punching, the outer contour comprising a bottom surface having a rectangular shape and four side walls extending from the bottom surface of the bottom surface, wherein the groove is located at each side wall and the a joint of the bottom surface, and each side wall is vertically folded along the groove to obtain a young material, and the inner surface of the cutting material is further adhered to the inner liner of the cut outer contour, and the outer surface is adhered The carton is made from a paper.

However, although such a manufacturing method can obtain better verticality and sharpness, in actual operation, since the thickness of the paper material is different and the ductility is also different, the cardboard sleeve after the gouging is often placed. When the cutting is performed in the cutting mold, the position at which the cutting is performed is shifted, resulting in the occurrence of defective products and wasting more material cost. Moreover, the inner liner paper must be manually aligned and pasted, which not only takes time and costs more labor costs, but also increases the manufacturing cost. Therefore, it is necessary to make a thorough improvement on the production process, and the quality can be better. Finished products, and effectively reduce manufacturing costs.

In view of the above, an object of the present invention is to provide a method for manufacturing a carton, which can improve manufacturing efficiency and reduce the defective rate of the finished product, and can reduce the manufacturing cost.

In order to achieve the above object, the method of the present invention for manufacturing a carton comprises: providing a substrate; first punching the substrate to form a plurality of pellets having a polygonal outer contour, and each of the cuttings A locating portion is formed at the intersection of the adjacent sides; a locating groove is formed on one side of the cullet to form a trough-shaped groove corresponding to the locating portion; and a lining paper is adhered to the stalk having the sigmoid groove One side; the second blanking of the material to determine the height of the outer contour of the carton and the surrounding side walls, and at the same time cutting the inner liner at the outer contour of the carton; along the well-shaped groove The trough folds the young material and causes the side walls to stand upright; and a sheet of paper is adhered to the surface of the young material to form the carton.

Wherein, the substrate is one of T-thickness, and the depth of the well-shaped groove is greater than or equal to 0.5T to increase the straight angle of the edge of the carton after folding.

Each of the positioning portions is connected by a horizontal line and a vertical line to form an L-shape, and the adjacent horizontal lines or each of the vertical lines are collinear.

In order to further enhance the aesthetics of the inner surface after the finished product is finished, a step of "corresponding to the positioning portion and grooving one side of the young material to form a well-shaped groove" is adhered to The cutting material has one side of the well-shaped groove, and the grooved portion on the inner surface of the inner surface is shielded by the inner liner paper.

Accordingly, according to the manufacturing process of the present invention, it can be applied to paper materials of various shapes or thicknesses, and a plurality of positioning portions are determined by the first punching, and then the positioning portions are used for positioning to perform the shaving to accurately The well-shaped groove is formed, and then the inner liner is pasted, and the second outer punching is performed to determine the desired outer contour and the height of the side walls, so that an accurate outer contour and a side wall height can be obtained. Finally, the folding and pasting of the paper is completed, and the proper positioning can make the trenching work smoothly, and the time and error of using the manual bonding can be greatly reduced, thereby improving the manufacturing efficiency and reducing the defective rate of the finished product. And can reduce the cost of manufacturing and other purposes.

A second object of the present invention is to provide a carton obtained by the method of manufacturing the carton, which can be passed through the positioning portions. The arrangement of the well-shaped groove is more accurate, thereby improving the quality of the finished product.

In order to achieve the above object, the carton of the present invention comprises: a substrate having a first side and a second side on each of the two sides, the substrate being a polygonal sheet-like structure along the substrate Each side has a side wall extending outwardly, and a groove is formed between the side wall and the substrate on the first surface, and a surface is coated on the second side of the substrate. The carton is formed by connecting the side walls.

Wherein, the substrate is one of T thick cardboard, and the depth of the groove is greater than or equal to 0.5T to increase the straight angle of the edge of the paper box after folding.

In one embodiment, the paper tray of the present invention further has a liner paper adhered to the first side of the substrate to cover the grooves. And the liner paper has a cross shape corresponding to the shape of the substrate and the side walls.

Wherein, the surface paper has a cross shape corresponding to the shape of the substrate and the side walls, and the peripheral edge of the paper sheet is provided with a plurality of connecting portions corresponding to the side walls.
