Gift packaging box manufacturers: detailed explanation of the common problems and solutions in the mounting pit process
Common problem one: mounting paper position
In order to avoid the deviation of the positioning of the paper, resulting in the phenomenon of incorrect horizontal mounting, when placing the face paper and corrugated paper, the position needs to be aligned left and right. If the upper and lower chain position of the machine is not adjusted; The paper stopper limit device does not hold the paper tightly by the paper edge, so that the paper pile moves from side to side; The paper in the
Gift Box is not neatly collected and placed, which will cause errors in the face paper and corrugated paper labeling. There are such cases that need to be noted: when the mounting color printing paper is relatively thin and curly, the speed of the machine can not be too fast.
Secondly, the machine, positioning structure adjustment or maintenance is improper, this reason will also cause the emergence of errors.
The paper feeding chain is loose, so that the upper and lower chain work is inconsistent, and the paper edge will collide with each other.
When the contact position of the opposite side of the paper is wrong or the gap is too large, it can not slow down the inertia of the high-speed movement of the cardboard.
The upper/lower roller is not cleaned in place, and a certain amount of glue accumulates, which blocks the synchronous rolling transport of facial paper or corrugated cardboard.
The gap between the upper and lower rollers of the machine and the poor paper feeding will also cause the board mounting error. The gift packaging box appears empty or skewed in the paper feed, because the cardboard handover time is not the same, the paper is not uniform, it is easy to bubble, degumming and mounting inaccurate.
Common problem 2: The surface of the "washboard" phenomenon after mounting
There are three ways to solve this problem:
1, the replacement of high quantitative tissue, but it will increase the cost so that the price of the gift box will increase a little.
2, improve the solid content of corn starch adhesive, reduce the amount of glue, less water absorption of color paper in the pitting process also improve this phenomenon.
3. Ensure that the straight thread of the face paper and the corrugated cardboard form a "ten" mounting direction.
Common problem 3: Cardboard warping after mounting pit
Gift Boxes improve this phenomenon, Deno is doing so.
1, improve the solid content of the pit glue and reduce the amount of glue. Because when the solid content is higher, the glue contains less water, and the amount of glue is reduced, so that the unit area of cardboard absorbs a large amount of water, can achieve the purpose of improving warping.
2, the direction of the paper grain is correct, that is, the straight thread of the face paper and the corrugated cardboard are "ten" mounted.
3. Stack correctly.
4, the direct way is to apply a certain amount of pressure on the seriously warped cardboard, so that the cardboard is improved.
Common problem four: packaging products appear delamination
When the proportion of effective bonding material in the glue is too low, the viscosity of the glue is too low, the quality of the adhesive is not good enough, and it is easy to make the packaging delamination. There are also too little glue, need to carefully check the quality of glue and glue.
