Exchange of experiences: Impact of adjustment skills folding machine
Newspaper rotary press, there are two principle ways in different cross-fold, one for the impact of folding, a folding for the splint. As the impact of folding has a simple structure and easy adjustment, newspaper rotary press was widely used. Although the impact of folding there are changes when the machine operating speed, the newspaper products on the crease position will change, especially when the large amount of newspaper printing ink roller embossing folder easily folding and other shortcomings, but Newspapers are not very high quality requirements, so long as the question is not very serious, impact Folding Machine These shortcomings will be completely overshadowed by its merits.
Impact the work of folding process is as follows:
printed tape after longitudinal fractures by the triangles, roll and pull the paper through the guide roller, by folding the pick roller pin hook;
tape cutting knife in the folding drum pads and cut through between the roller cutting knife, serrated knife to cut sheet cutting;
folding knife rollers on the planet into a pair of folding the paper clip to complete cross-fold between rollers;
folded folding paper folder from falling into the wing between the wheels roll, and then sent to conveyor belt.
To use a good Impact Folding Machine The key is to make fold roller adjustments, but this is difficult to grasp. Following the impact of the Japanese-style folding machine Gaussian example, to do an introduction.
1. Folding roller and the cutting roller to adjust the relative position
In the assembly, folding knife, a cutting drum pads should be on the cutting drum cutting serrated knife is right. Folding roller and the cutting drum by a pair of mutually meshing gears, cutting drum and the drive gear as the key link, folding roller and drive gear for the long-hole screw connection, to change the length of the screw connection hole locations, can achieve folding drum gear to adjust the relative position and purpose. The micro adjustment can change the pinhole and the cutting edge pick distance to achieve, but does not favor changing the actual production here.
2. Pick needle adjustment Pick needle telescopic movement by the drive side of the cam control, pick needle retractable travel decisions by the cam, but pick needles out of each folding roller surface height can be adjusted independently. To ensure the needle is fully retracted folding pick inside the drum to pick out folding roller pin should be less than the height of the surface of the retractable needle pick stroke. Needle out of a high degree of measurement challenges to the folding roller pin to pick out the largest amount of time to pick out folding needle roller surface height as a standard 6mm. Depending on the thickness of the actual production of folding quote request, you can fine-tune the high pick out the needle.
In the folding process, the pick needle is pre-stretching, with the folding roller rotation, pick a needle out of the bar into the tape, so pick a needle out of time does not require very accurate adjustment may not take into account time of pick out the needle. But when the knife into the paper roll when the folding folder, select pin must be promptly retracted, the needle of the indentation time of challenge to be very accurate, otherwise the indent is too stretched out and party because of torn paper folding, indentation too early they make paper out of control with a period of time, affect the folding precision. Moreover, the pick needle indentation process should be quick to pick pin and Planetary knife coordinated action. Adjustment, loosen the drive side of the pick needle cam fastening screws, or if the indentation is too early would pick needle roller cam towards the forward direction of folding mobile, but too late, they will pick pin indentation towards folding roller cam the reverse direction.
3. Knife height adjustment
Knife folding roller spindle is the operation of gear by a planetary motion, so that both folding axis rotation, another revolution. Knife rotation and revolution of the drive wheels than the sun and planets to represent the relationship between the number of teeth. As the knife is actually the rotation of planetary gear rotation, and revolution is the folding knife rotating drum, so that turns a folding roller, folding knife out of a total of 3 times, 3 times the phase difference is 120 °, only the down out of time before the middle of the folding roller insert clip to complete the cross-fold action reported.
