Paperback Filament Production Failure and Quality Control (2)

2. Slicing problems 1) Inconsistent up and down linking The slitting knives should be aligned with the slitting line so that the two books on the top and bottom are basically the same.

2) The parallel lines of the two pushing blocks in the process of skewing the left and right skewers are not perpendicular to the middle knife or the skew of the track is too narrow; the pressure on both sides of the present pressure plate is inconsistent or too light; the cutting is continued or the raw edges are serious; The blade is sharpened.

3. Three-sided cutting problem 1) After the cutting, the large and small blades on the finished book are blunt, making the size of the door knife inconsistent; the delivery trolley is not perpendicular to the work platform and the pressure of the paper press is light; the cutting height exceeds the design height. The pressure of the paper press is large, the pulling force is increased, and the paper is bent and deformed greatly; the side blade is too narrow or the upper edge of the back is knocked when sharpening, and the knife edge and the cutting surface should be at a certain angle.

2) There is a skewed book carrier on the right and left sides and the doorknife is not parallel to produce incisions; the gap between books is not properly conveyed through the books, and the over-tight conveying resistance is too large, and the looseness and looseness are too unstable; the side cutters have different sizes before and after measuring on the knife holder. , should replace the knife case or calibration knife holder; the brush is not in place and the book block is not flush, push the book is not stable.

3) The book should be broken to ensure that the glue layer is between 0.8 and 7.2mm, the plastic tray is level and the package is empty; the cover paper is poor or the paper is not in the correct direction; the bookbinding time is too short or not Tight; milling back is not smooth, making the rubber back loose, increasing the thickness of the book back. Slots are not smooth, fast, and the side glue is too thick; the jacking plate is not used properly, it is not pressed on the cutter head of the sky or the ground, and tearing occurs; the stapled book is slanted back; the blade is not fast and the corner angle is too small. Scoop up the glue on the blade and wax or talc; use a guillotine machine with a broaching knife.

4) The burr blade is generally about 0.5mm into the blade, and it should be frequently replaced by high-quality knife blades.

5) Swords are broken, broken or chipped.

6) When the size of the doorknife is large and small, it may cause looseness if the adjustment screw cannot be locked, and the roller is worn and worn; the roller of the trolley track is worn and improperly adjusted; the needle bearing of the trolley arm swing sleeve bearing is worn and damaged, causing The swing of the trolley is large and small.
