Pasting process and operation precautions of carton cover of carton gluing machine

The booming market extends the application of carton to various fields. In addition to printing exquisite pictures, carton production also needs to process lining paper, die-cutting, forming and facing paper. The quality of each process has a direct impact on the quality of the final product. Therefore, each process is very important. At present, many cartons are pasted manually in China. This paper introduces the key points of the pasting process and operation precautions of carton cover of carton gluing machine.

Lining paper

1. Pasting process and operation precautions of carton cover of carton gluing machine about equipment and auxiliary materials.

The required equipment mainly includes glue passing machine and flattening machine. Latex is required as auxiliary material.

2. Pasting process and operation precautions of carton cover of carton gluing machine about key points of process.

a.Check the production sheet and check the quality of carton board. The standard moisture content of carton board is 12%.

b. Prepare adhesive. The mass ratio of each component is: white latex: water = 3:1.

c. On the platen in front of the glue passing machine, the paper pusher pushes it to the operators on both sides one by one according to the speed of the glue passing machine. The operator first receives the box board paper, then receives the glue coated inner paper, and aligns it with the two regular sides of the box board paper. When receiving paper, the two people should cooperate tacitly. A little negligence may cause the paper to crack or wrinkle.

d. Flatten. After colliding the box board paper mounted with lining paper, put it into the flattening machine. The pressure is set to 20MPa for 5 minutes.

e. After production, self check the quality, count the quantity, hang the production signboard, and transfer to the next process for production.

f. The inspection items include the cleanliness of the paper surface, such as glue overflow, adhesion and cleanliness.

3. Pasting process and operation precautions of carton cover of carton gluing machine about precautions.

a.Pay attention to the influence of adhesive ratio on the surface flatness of paper, and master the uniformity during gluing.

b. When mounting the lining paper, it must be flat and in place. Note that the lining paper cannot exceed the regular edge of the box board paper.

c. The prepared adhesive shall not be too thin to prevent wrinkling of the inner paper.

d. Wash hands frequently to ensure that the paper is clean.

Forming and laminating paper

Forming and mounting paper is the most demanding and cumbersome process in the box making process. Only in the production process, can the quality be guaranteed.This paper introduces the key points of the pasting process and operation precautions of carton cover of carton gluing machine.

1.Pasting process and operation precautions of carton cover of carton gluing machine about equipment, molds and auxiliary materials.

The required equipment includes glue passing machine and punching machine.The required dies include scraping ruler, auxiliary block, punching die, plastic container and brown brush.The required auxiliary materials include 168 glue, pair mounting glue, rubber band, absolute ethanol and cotton cloth.

2.Pasting process and operation precautions of carton cover of carton gluing machine about key points of process.

a.Check the production order and production sample, and check whether the materials are qualified.

b. First article inspection and confirmation before mass production.

c. Combined box body. Stack the die-cut box board paper on the table, and evenly brush the small edges on both sides. Lift up the four sides of the glue coated box board paper, press the large side against the small side, tighten it with two rubber bands, stagger 45 ° and stack it on the pallet. After passing the self inspection, hang the signboard, and move to the next process after air drying.

d. Mount the box body.

Apply glue evenly to the face paper of the box body, and accurately place the box type in the frame line on the back of the face paper. 

Put on the auxiliary block and bend the four sides downward at an angle of 90 °.

Take out the auxiliary block, fold the bleeding edge inward, and scrape the four sides of the box with a bamboo ruler to make it fully bonded. Turn the box upside down and scrape the four edges and corners with thumb nail. 

Then put on the auxiliary block, wipe the face paper from inside to outside with flannelette.

If there is glue stain, wipe it with flannelette dipped in a little ethanol. Exhaust the air to make it closely combined. 

When drilling, ensure that the hole position is appropriate.

e. If the self inspection quality is qualified, the heaven and earth cover shall be buckled, the quantity shall be counted, the signboard shall be hung, and it shall be handed over for inspection and packaging.

3.Pasting process and operation precautions of carton cover of carton gluing machine about precautions.

a.When assembling the box body, the four corners of the carton must be tight and seamless, and the four corners and the upper edge must be flush. If it is too close to the inside or outside, it will bring trouble to the mounting paper. It is strictly prohibited to move to the next process before the adhesive is dry.

b. When mounting paper, be sure to wipe it with flannelette to make it stick firmly, and make the surface smooth without bubbles and glue stains.

c. When scraping the edge with a scraping ruler, the four sides must be scraped in place to prevent the four corner interfaces from warping or wrinkles.

d. Keep your hands clean and the console clean to prevent dirty operations from fouling the lining paper in the box
