Abstract

The invention belongs to the technical field of packaging boxes, and particularly relates to a manufacturing process of a packaging box, which comprises the following steps: mounting paper on the front surface of the paperboard; die cutting the paperboard mounted with the facial tissue into a plurality of unit boards; slotting the reverse side of each unit plate, wherein the middle of each unit plate is a packing box bottom plate, and four sides of the packing box bottom plate are four side plates of the packing box; dispensing glue at the open slot, folding four side plates of the four sides of the bottom plate of the packing box to make the four side plates and the bottom plate of the packing box adhere to form a rectangular box without an upper cover; and coating edges on the upper edges of the four side plates. The invention has simple process and low production efficiency, and the manufactured packaging box has high surface flatness.

Description

Manufacturing process of a packaging box

technical field

The invention belongs to the technical field of packing boxes, and in particular relates to a manufacturing process of packing boxes.

Background technique

One of the most common box types in the packaging industry is the upper and lower cover (heaven and earth cover). The production and processing methods of the upper cover and the lower cover are basically the same. They are composed of two parts, the box blank and the facial tissue. Due to the traditional packaging Due to the influence of production and processing technology, the packaging box has the following problems and shortcomings:

1. The process is complicated and the processing cost is high

2. Large material waste and low utilization rate

3. Long production lead time

4. Low surface flatness

5. High labor cost

6. Low production efficiency

7. The verticality of adjacent surfaces is not good enough

8. There is a large gap between the upper and lower covers

9. The speed when the natural slide is turned on is not easy to control

10. The high proportion of manual participation in production leads to unstable quality.

Contents of the invention

The purpose of the present invention is to provide a manufacturing process of a packaging box.

The technical solution of the present invention is: a manufacturing process of a packaging box, comprising the following steps:

Step 1: Mount the paper on the front of the cardboard;

Step 2: Die-cut the cardboard mounted with face paper and divide it into several unit boards;

Step 3: Groove the reverse side of each unit board, the middle of each unit board is the bottom plate of the packing box, and the four sides of the bottom plate of the packing box are the four side plates of the packing box;

Step 4: Apply glue to the slot, fold up the four side panels on the four sides of the bottom plate of the box to bond them to the bottom plate of the box to form a rectangular box without a top cover;

Step 5: Paint edges on the upper edges of the four side panels.

The beneficial effects of the present invention are:

1. Simplified process and low processing cost; 2. Less material waste and higher utilization rate; 3. Shortened production delivery cycle; 4. Improved surface flatness; 5. Low labor cost; 6. High production efficiency; 7. Adjacent surfaces Good verticality; 8. The gap between the upper and lower covers is smaller; 9. The speed of natural sliding and opening is easy to control; 10. The proportion of manual production is small, and the production quality is stable.

Detailed ways

Describe in detail below in conjunction with the embodiment of the present invention:

Please refer to Figure 3, a manufacturing process of a packaging box, comprising the following steps:

Step 1: Mount the paper on the front of the cardboard;

Step 2: Die-cut the cardboard mounted with face paper and divide it into several unit boards;

Step 3: Groove the reverse side of each unit board, the middle of each unit board is the bottom plate of the packing box, and the four sides of the bottom plate of the packing box are the four side plates of the packing box;

Step 4: Apply glue to the slot, fold up the four side panels on the four sides of the bottom plate of the box to bond them to the bottom plate of the box to form a rectangular box without a top cover;

Step 5: Paint edges on the upper edges of the four side panels.

Please refer to Fig. 1, the manufacturing process of the first traditional packing box includes the following steps:

Step 1: Cut the target cardboard, die-cut the cardboard, and cut it into several unit boards;

Step 2: Grooving each unit board to form a box blank;

Step 3: Paste the folded box embryo with adhesive tape;

Step 4: Print the face paper, die-cut the face paper, and cut it into several unit face papers;

Step 5: Groove the opposite side of the face paper of each unit;

Step 6: Apply glue to the back of the unit face paper;

Step 7: The glued side of the unit face paper is glued to the folded box embryo, and the side of the unit face paper is folded upwards at 90 degrees and glued to the cardboard;

Step 8: Fold and glue the part of the side of the face paper that is higher than the side of the cardboard to the inside of the side panel of the cardboard.

Please refer to Fig. 2, the manufacturing process of the second traditional packing box includes the following steps:

Step 1: Cut the target cardboard, die-cut the cardboard, and cut it into several unit boards;

Step 2: Grooving each unit board to form a box blank;

Step 3: Paste the folded box embryo with adhesive tape;

Step 4: Print the face paper, die-cut the face paper, and cut it into several unit face papers;

Step 6: Apply glue to the back of the unit face paper;

Step 7: The glued side of the unit face paper is glued to the folded box embryo, and the side of the unit face paper is folded upwards at 90 degrees and glued to the cardboard;

Step 8: Fold and glue the part of the side of the face paper that is higher than the side of the cardboard to the inside of the side panel of the cardboard.

The first traditional packaging box production process requires separate die-cutting and slotting of the facial tissue and cardboard. The steps are cumbersome and time-consuming, and the production efficiency is low. The second traditional packaging box production process requires separate die-cutting of the facial tissue and cardboard. , omitting the grooved step of the face paper and directly sticking the un-grooved face paper to the grooved cardboard, the problem of low surface flatness is prone to occur.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the claims of the present invention shall fall within the scope of the claims of the present invention.
