The traditional slitting and crimping machine can no longer meet the needs of the current multi-variety and multi-specification orders. Its manual order change time is long and the efficiency is low. Moreover, the mechanical slitting and creasing machine is generally equipped with double-blade cutting. After trimming, both sides of the corrugated cardboard are flattened and deformed. If this traditional slitting and dividing press is replaced with a computer thin-slider slitting and pressing machine, the computer can change orders, automatically arrange the knives, high-quality thin blades can automatically sharpen the knife, the paper edge is cut and smooth, and the corrugation does not deform. Due to the different mechanical structure, the improvement of the slitting machine generally needs to be replaced.
The cross-cutting machine has experienced manual type, single-sided paper cutting type, mechanical control type, computer controlled straight knife type, computer controlled spiral knife type. In the production process of mechanically controlled cross-cutting machines, the loss of order change is too large, and the paper cutting error is large. At present, many large-scale enterprises have been eliminated. The computer-controlled straight-blade cross-cutting machine is the most mature computer-controlled cross-cutting machine with the most mature technology and the lowest cost of use and maintenance. The thickness of the straight knife used is large. There will be no problems during the year, and the price is lower. Computer-controlled spiral cutter cross-cutting machine is the latest technology. The cross-cutting machine design supported by this technology adopts low-rotation inertia cutter shaft design. The cutter shaft is smaller, the control difficulty coefficient is relatively low, and the power is small, which can achieve Production speed requirements.
At present, the computer control of the cross-cutting machine is divided into DC computer control, DC servo control, AC servo control, and calibration cut-off control. Ordinary DC control systems have more manufacturing enterprises, longer production time, and lower market prices. The DC servo control system is a technology developed on the basis of the DC control system. In the production process of the cross-cutting machine, the brake needs to be applied after the paper is cut and the impulse module is installed. Certain power saving function. The AC servo control system is the latest technology, it can be applied to the production of higher speed and higher cutting accuracy requirements. The calibration and cutting technology emerges with the application of pre-printing technology in the production of corrugated cardboard. The current computer control system can be installed with this system. The better configuration is to install the calibration and cutting system with the AC servo control system. High cutting accuracy.
