Release Time:2019-3-20 Click:93

(1) Determine the correct folding method of the paper on the machine. Please fold the folding sheet in the order of page number to open the folding sheet. In general, take one-half of the width of the paper (the upper and lower sides of the paper are aligned with the folding in the middle) Centerline of the paper table. Loosen the handle and adjust the paper gauge and the paper bar on the paper table to the edge of the paper.
(2) Determine the paper feeding direction according to the folding method. (usually the standard of the printing of the Shanghai printing factory as the folding paper)
(3) Finishing the paper for paper feeding makes it easy to fly smoothly. (Jitter paper eliminates the adsorption of paper due to static electricity, ink drying, etc., and the paper head prevents the paper from being damaged due to moisture, deformation, etc., and the finished paper is neatly stacked on the paper table. .)
(4) After finishing the paper (confirm that the selector switch is at the corresponding function position), press the paper table up start button, and the paper table rises to a certain height. Under the action of electric eye monitoring, it automatically changes to a slow speed and adjusts the working position of the feeder. The height detecting lever and the platen at the both ends are pressed against the edge of the stack to automatically adjust the working height of the paper separator when the paper hits the detecting lever.
(5) Loosen the star screw, push the paper positioning plate toward the outer side of the paper, close the paper edge and tighten the star screw, and adjust the number of paper bars required on the bridge. And the position to ensure the smoothness of the paper feeding process.
(6) Select the digit and orientation of the fence board according to the folding method of folding. Adjust the gauge of the fence panel to the corresponding position according to the required size of each fold of the finished product. If there is a deviation, the knob on the outside of the adjustment disc can be loosened to fine tune until it matches the sample size.
(7) Fold the folded paper to the paper, press the pressure roller support of the folding roller, that is, the pressure plate below the adjustment knob. Usually, the paper is placed into each pressure bearing in turn according to the thickness of each group of folding rollers. In the lower platen.
(8) Select the punching knife, the indentation knife according to the binding and folding method, and press the emergency stop button to shake the transmission handwheel. Use the hex wrench to loosen the tool wheel on the tool shaft and move it to the upper blade. Tighten the cutter wheel after the wheel is pressed. (If you need to pay attention to the blade when installing the blade: the number of blades; whether the blade is sharp and effective; the direction of the blade cannot be reversed)
(9) The working position of the electric eye and the working frequency of the electronic knife. According to the working detection range of the paper passing the working detection range of the electric eye and adjusting the frequency of the dial switch (or selecting the fast/medium/slow three gears), the folded paper can be smoothly brought under the electric control knife action. A folding link.
(10) Adjust the various machine and folding work parameters in the touch screen.
(11) Adjust the double-sheet detection mechanism so that one sheet of paper can pass smoothly and cannot pass through two sheets.
(12) Start the main machine to move normally, start the fan, fine-tune the Feida height and the mouthpiece, the air volume of the nozzle, the length of the paper brush or the iron piece. Try to check whether the machine is working abnormally and check the quality of the parts. After reaching the standard and taking the first signature to confirm that everything is normal, you can carry out large-scale folding production and arrange the folded products on the prepared card board.
