Flexible adaptation to the market | Basic principles and adjustment steps of the folder gluer machine

The folder gluer machine is a commonly used automatic packaging equipment, mainly used to fold, glue, and shape cardboard into boxes. This article allows you to understand how the folder-gluer machine works, how to correctly adjust the machine so that it can be used normally, and what solutions are available for problems that arise.

Basic principles of folder gluer machine

The basic principle of the folder gluer machine is to cut the corrugated cardboard into a set size through the machine's paper feeding system and folding system, and then use the sewing machine head to glue and glue the edges of the cardboard with the trademark printed on it to complete the forming of the carton. The gluing efficiency, bonding quality, registration accuracy, etc. of the folder gluer machine directly affect the efficiency and quality of subsequent processes (such as grooving, die-cutting, pasting, etc.), so for printing and packaging companies with high production efficiency requirements , it is very necessary to choose a folder-gluer with stable quality and complete functions.

Folder gluing machine adjustment steps

(01) Carefully check the work order and samples to determine the box glue used and prepare them;
(02) Adjust the width of the baffle of the box to be glued. The two sides should be parallel, and the semi-finished color box to be produced has just been put down. The distance between the side baffles on both sides of the color box is less than 1mm. Then adjust the limiting bolts to ensure that each product to be glued is smooth. The phenomenon of passing without fetters appears;
(03) Adjust the slope and height of the bracket in the box-to-be-glued area so that the product to be glued can move forward smoothly without snagging. After pressing, adjust the auxiliary guide rail and the flow wheel. Make the size suitable for the specifications of the color box to be pasted;
(04) Adjust the box-gluing support belt and box-gluing guide rail, then adjust the box-gluing host and wheel closing pressure, and the cross-matching of the belt.
(05) Adjust the glue tank and check whether the glue in the glue tank is sufficient. The amount of glue should submerge 80% of the rubber wheel. Then adjust the glue tank and glue position;
(06) Turn on the power switch, motor switch and vibration switch key. After adjusting the machine, press the "Run" or "Inch" key, and then press the "Feed" key to debug the machine, and check whether there is any abnormality in the performance of the machine. If there is any skew, it should be Correct immediately;
(07) After debugging is ok, test the machine for 5-10 sheets first, confirm the position and molding specifications, and then adjust the machine speed;
(08) When gluing boxes, pay attention to the paper feeding status of the boxes, and do not over-line, offline or misalignment, so as not to affect the appearance and molding effect of the color box;
(09) First confirm: Strictly follow the first sample signing method;
(10) After production is completed, clean the machine and keep it clean.

What problems will occur during the gluing process of the folder gluer machine and the corresponding solutions?

(01) The glue is not strong: You can check the amount of glue applied. If the amount of glue is too much or too thick, it will cause whitening. If the amount of glue is too little, the glue will not be strong, so you must rely on experience. Keep the quantity in mind.
(02) Scratches on the surface of the plastic box: Especially small boxes are often difficult to crease with belts. You can cover them with a layer of film first, but the sticky edges cannot be covered, otherwise it will be difficult to glue.
(03) The glue box is not glued in the correct direction: This requires adjusting the position of the plastic box and balancing the pressure of each part. This can be handled with the experience of the folder gluer machine captain.

In summary, this article will tell you the basic principles of the folder-gluer, the machine adjustment steps and the solutions to the corresponding problems. For companies that need to produce packaging in large quantities, it will be cost-effective to choose an efficient and stable folder-gluer. investment options.
