Analysis of auxiliary die cutting tool forming system

The die-cut version of the laser cutting system consists of a laser processing head, computer-aided design (cAD) software, a computer numerical control device (CNC), a work bench, and the like. The laser processing head consists of a focusing lens, a gas nozzle, a height sensor, etc. It is driven by a servo motor and the height sensor controls the spatial position of the focus. The graphics are cut out by the relative motion of the table and the laser beam. When the cutting process should be written according to the requirements of leaving the bridge, bridging and cutting border program to determine the best path for die-cutting laser cutting. The computer numerical control device (CNC) adopts microprocessor-controlled programmable logic control technology. After the CNC software generated by CAD is sent to the CNC, it can control the laser cutting of plywood, including fault detection, servo drive and positioning, and auxiliary gas pressure control. Wait. The expert system can automatically select the best process parameters (power, speed, pressure, etc.) according to the type, performance, thickness, and processing requirements of the sheet. The use of laser-cutting die-cutting plates is not only faster and more precise, but also more reproducible, especially when cutting multiple plates and repetitively making die-cut plates.

Die cutting tool forming system

In order to ensure the precision of the die-cut version, the length of the die-cutting tool and indentation knife and the size of the bridging notch are automatically calculated using CAD software and transmitted to a computer-controlled tool forming machine for grooving, cutting, bending, and cutting. Due to the adoption of hydraulic machete, liquid crystal display, hydraulic drive and cursor positioning, the accuracy of tool forming is effectively guaranteed.

. Bottom (backing) CAM system

When the backing is machined with a computer aided engraver, the width of the indentation groove, the depth of cut, and the accuracy shall meet the requirements, and the engraving speed and depth shall be adjustable. Using CAM technology can not only shorten the production cycle, but also improve the manufacturing accuracy of the carton.

. Box type proofing

In order to verify the rationality of the design of the carton structure, prior to the mass production, a certain amount of carton samples were sampled using the multi-purpose carton sample CAM equipment. After soliciting opinions from users and consumers, they were revised or redesigned to avoid batch production. The design and manufacturing of the rear carton structure are unreasonable; it is also possible to check whether the design meets the user's requirements. The multi-purpose cassette CAM system is equipped with a combined cutter and knife. When the control part receives the execution instruction, the executing part automatically selects the indentation and cutting tool according to its cardboard type, and automatically performs drawing, indentation, and cutting according to the computer-aided design data and program, and can realize automatic tool change. The MARPL0T multi-purpose carton sample CAM system developed by MARBACH has a maximum processing size of 1020mln×1420mln and a maximum speed of 40m/min. The KongsbergXXL40 series die-cutting machine introduced by Barco Graphics Co., Ltd. is mainly used for the sample production and short-run production of corrugated paper box and folding carton, and the performance can be improved by 2596. The front end of the aircraft is equipped with a Pc machine. The system uses bar code technology for adjustment and can automatically correct when an error occurs.

. Cartridge Direct Manufacturing Technology

The Boarder folding carton laser processing system introduced by MARBACH in Germany is known as a revolution in folding carton processing in Europe. The device uses C0. The laser beam directly processes the folding indentation line and the trimming edge of the carton on the cardboard, which has high speed and high precision. It can process paperboard with grammage less than 1500g/m2 and B-tile to 3-layer corrugated cardboard. Using this system to process a batch of cartons can greatly shorten the production cycle. Processing medium and small batches of standard paper boxes can also greatly reduce processing costs.

. Die cutting technology

Flat die cutting

Sheet-fed flat die-cutting is based on the mechanical positioning of the front gauge and side gauges, while flat die-cutting is based on printed marks and does not have a gripper row.

In order to realize the transition of the intermittent printing of the paper of the rotary printing unit to the die cutting station, an adjustable eccentric mechanism is usually provided in the paper feeding device. The in-line flattening die-cutting machine produced by BOBST Company uses the adjustment unit and the measuring roller to ensure the reliable feeding of the paper; adopting the die-cutting printing register and quality control system to avoid the instability of the mechanical backlash; and Automatically remove web connectors and waste products.
