What Is The Function Of High-speed Die-cutting Machine And How To Maintain It

High-speed die-cutting machines are essential processing equipment for the printing and packaging industry, as well as for electronics and automotive interiors. Its core functions are precise cutting, folding, stamping or laminating of non-metallic materials (e.g. double-sided adhesive tape, backlight, black and white adhesive, waterproof foam, PE/PP/PVC and electronic adhesive pads) using die-cutting machines, steel blades or metal molds. These machines have the following functions:

Printed products or cardboard can be rolled into specific shapes (such as cell phone parts, carton components and labels) to meet product packaging or functional requirements. For example, the DP620 high-speed die-cutter is suitable for large displays, copper, aluminum and platinum, as well as conductive products. Die cutting speed can be up to 200 times perminute, greatly increasing production efficiency.

Multi-Function Integration:
Some models support a variety of processes, including die-cutting, creasing -
ing, hot stamping, laminating, automatic waste removal. For example, fully automatic plate die-cutting machines can simultaneously die-cut and crease -
Some machines can also perform holographic hot stamping. High precision processing:
Optical sensor or laser positioning technology ensures ± 0.1-0.2mm cutting accuracy and satisfies extremely high dimensional accuracy requirements in applications such as electronic packaging and high-end gift boxes.

Optimized nesting design such as DP620 reduce material waste and unit costs.
Maintenance High-Speed ​​Die-Cutters
Daily cleaning, lubrication, periodic inspection and professional maintenance are essential to ensure long-term and stable operation of high-speed die-cutting machines:

1. Daily cleaning

At the end each day's work, clean the machine with waste paper and fibres. This prevents debris from entering the chain drive and die-cutting platforms or obstructing the photoelectric detection head, thus preventing breakdowns.

Focus on cleaning die cutting blades, disc cutters and rollers to maintain sharp edges and ensure good cutting quality. Use professional cleaning products (such as oil and wipes) to avoid chemical corrosion. Lubrication and Maintenance

Oil lubricated side gauges, gears, cam travel bearings, pressure rods, feeder head cams and steering joints. The main chain shall be lubricated with an automatic lubricating device to maintain oil level and grade.

Lubricate the front gauge adjustment and cam with chain oil, lubricate the gauge drive chain with grease, lubricate the spring with grease. Feed cam and drive chain should also be lubricated.

Check the lubrication moving parts thoroughly and replace worn lubricating oil to ensure the smooth flow of oil.

3. Regular Inspections

Check screws and fasteners weekly for looseness, adjust and tighten in time to prevent loss or damage of parts caused by vibration.

Ensure electrical connections are secure and switches and buttons function properly. If the equipment is control system by PLC, the ladder logic diagram should be checked regularly for electrical faults.

Check cylinder and airway for leaks or damage to ensure proper functioning of the pneumatic system. Professional maintenance

Comprehensive professional maintenance is carried out at least once a year, with technicians inspecting and adjusting all parts of the machine to ensure accurate calibration and efficient operation.

Replace key parts such as motor and control system on a regular basis according to usage to prolong the service life of the equipment.

Ensure operators are familiar with maintenance procedures and safety protocols (such as switching off power and using the correct tools) to reduce malfunctions caused by human error.

Dust control is of the utmost importance: Waste paper edges easily clog moving parts, should be cleaned first.
Lubrication Specifications: Avoid mixing different brands or types of lubricants to prevent chemical corrosion.
Data recording: records the date, project and personnel of maintenance to facilitate historical tracking and subsequent maintenance planning.
Safe operation: Make sure equipment is off before repair and wear protective gloves and glasses.
