During the use of the corrugated box stitching machine, the carton equipment should be adjusted to avoid blindness. Adjust the positions of the main baffle, left and right baffles, and upper and lower nail heads according to the flap of the carton. Pay attention to the fact that the left and right baffles cannot be clamped too much. It should ensure that the cardboard can be inserted and pulled out smoothly.
After the mechanical adjustment is completed, set the touch screen computer, such as: the height of the carton = the height of the original carton -40mm, the number of nails in the carton, the nail distance of the carton, the setting of whether to strengthen nails, etc., the selection of single and double sheets, etc. After all the above tasks are set up, trial production of the box stitching machine can be carried out.
If the thickness of the cardboard is too thick, personnel should be arranged to properly thin the binding part， so that the tissue paper will not be crushed during binding. The nailing should be carried out in accordance with the requirements of the production notice, and the box nails should be nailed along the centerline of the overlapping part, and the deviation should not exceed 3mm.
The nail distance should be uniform, the first and tail nails are 20mm from the upper and lower lines, the single nails are not more than 55mm, and the double nails are not more than 75mm. The two pieces of box blanks should be aligned, and there should be no scissor cuts.
After the order is completed, the folded carton should be square.
1) Carton with a comprehensive size less than or equal to 1000mm: The difference between the two diagonals of the top surface should not be greater than 3mm, the comprehensive deviation of the inner diameter of a single corrugated box is within ±2mm, and a double corrugated box is within ±4mm;
2) Carton with a comprehensive size greater than 1000mm: The difference between the two diagonals of the top surface should not be more than 5mm, the comprehensive deviation of the inner diameter of a single-corrugated carton should not be more than 3mm, and a double-corrugated carton should not be more than 5mm.
The hole diameter of the box corner shall not be greater than 4mm, and there shall be no obvious wrap angle, and the seam or overlap of the outer flap shall not be greater than 2mm. The nail box shall not have the phenomenon of inverted head nails, and the two pieces of box blanks with inconsistent yin and yang surfaces, varieties, and specifications shall not be mistakenly stapled together. The ordered cartons will go into production after being inspected and qualified.
When the nail box starts, the cardboard is fed by the servo motor, and the nail car motor drives the nail head to complete the nail box. The drive shaft driven by the nail head motor and equipped with a clutch and brake drives the crank mechanism to realize the nail box action under the action of the clutch. When the first nail action is completed, the cardboard backplane picks up the cardboard, and the crank mechanism moves in a stepping manner. Drive the paper feed roller to rotate, stop when the predetermined nail pitch is reached, and immediately perform the second nailing action. The key to box stitching machine is the quality of the nail car and the nail head, and product quality failures often occur here.
