Die-cut laser cutting system
The die-cutting laser cutting system consists of a laser processing head, computer aided design (cAD) software, a computer numerical control device (CNC), a workbench, and the like. The laser processing head is composed of a focusing lens, a gas nozzle, a height sensor, etc., and is driven by a servo motor, and the height sensor controls the spatial position of the focus. The pattern is cut by the relative motion of the table and the laser beam. When cutting, the bridge, bridge and cut frame procedures should be programmed according to the process requirements to determine the best path for die-cut laser cutting. The computer numerical control device (CNC) adopts microprocessor-controlled programmable logic control technology to control the laser cutting of the plywood after the CAD software generated by CAD is sent to the CNC, including fault detection, servo drive and positioning, auxiliary gas pressure control, etc. Wait. The expert system automatically selects the optimum process parameters (power, speed, pressure, etc.) based on the type, performance, thickness and processing requirements of the sheet. The use of laser-cut die-cutting is not only fast, high-precision, but also reproducible, especially when cutting multiple versions and repetitive die-cutting.
Die cutting tool forming system
In order to ensure the precision of the die-cutting plate, the length of the die-cutting knife and the indentation knife and the size of the bridge gap are automatically calculated by the CAD software, and transmitted to the computer-controlled tool forming machine for slotting, chamfering, bending and cutting. Thanks to the hydraulic machete, liquid crystal display, hydraulic drive and cursor positioning, the accuracy of tool forming is effectively guaranteed.
Bottom mold (backing) CAM system
When processing the backing with a computer-assisted engraving machine, the indentation groove width, cutting depth and precision should meet the requirements, and the engraving speed and depth should be adjustable. The application of CAM technology not only shortens the production cycle, but also improves the manufacturing precision of the carton.
Box proofing
In order to verify the rationality of the design of the carton structure, before the official mass production, use a multi-functional carton sample CAM device to prototype a certain amount of carton samples, solicit user or consumer opinions, then modify or redesign to avoid mass production. The design and manufacture of the rear carton structure is unreasonable; it is also possible to check whether the design meets the user's requirements. The multi-function carton sample CAM system is equipped with a combined cutter and press. When the control part receives the execution instruction, the execution part automatically selects the indentation and the cutting tool according to the type of the cardboard, and automatically draws, indents, and cuts according to the structural data and program of the computer-aided design, and can realize the 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 of die-cutting machines from Barco Graphics are mainly for sample preparation and short-run production of corrugated boxes and folding cartons, with an improved performance of 2,596. The front end of the machine is equipped with a Pc machine, and the system is adjusted by bar code technology, which can be automatically corrected when an error occurs.
Carton direct production technology
The Laser eater folding carton laser processing system introduced by MARBACH in Germany is called a revolution in folding carton processing in Europe. This device applies C0. The laser beam directly processes the folded indentation lines and trimming of the carton on the cardboard, which is fast and accurate. It can process paperboard with a weight less than 1500g/m2 and paperboard with a thickness of B corrugated to 3 layers of corrugated. Using this system to process a batch of cartons can greatly shorten the production cycle. Processing small and medium-sized standard cartons can also greatly reduce processing costs.
Die cutting technology
Flat die cutting
Sheet-fed flat die-cutting relies on the front gauge and side gauge mechanical positioning, while the in-line flat-press die-cutting is based on the printed mark and there is no gripper row.
In order to achieve a transition of the intermittent movement 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 flat die-cutting machine produced by BOBST uses the alignment unit and the measuring roller to ensure the reliable feeding of the paper; the die-cut registration and quality control system is adopted to avoid the instability of the mechanical backlash; Automatic removal of web joints and scrap.
