Guowang C80 Q die-cutting machine with stripping

Feeder

• Electronic detectors, microswitches and photoelectric sensors throughout the machine are controlled by a programmable logic controller (PLC)
• High-quality feeder (made in Taiwan) with 4 lifting suckers and 4 forwarding suckers for fast and stable sheet feeding. The height and angle of the suckers are easy to adjust so that sheets are fed straight.
• Mechanical double-sheet control, a late-sheet detection device and an adjustable air blower ensure reliable and precise sheet transport.
• Becker compressor
• Motorised lateral pile shift for precise loading
• The side lays can be switched between pull and push mode on both sides of the machine simply by turning a pin, without mounting or dismounting any parts. This ensures flexibility in processing a wide range of materials, regardless of whether the register marks are on the left or right side of the sheet.
• Automatic error display and automatic diagnostics.
• The side and front lays are equipped with precise optical sensors that detect black colour and plastic sheets. Sensor sensitivity is adjustable.
• Optical sensors with an automatic stop system on the feed table optimise the monitoring system for comprehensive quality control across the entire sheet width and in the event of a sheet jam.
• The control panel on the feeder, used to make the loading process easier to control, is equipped with an LED display
• Separate drive control for the main pile and auxiliary pile
• PLC and electronic cam for timing control
• Foreign object protection device helps prevent machine damage
• Swiss Rapplon feeder conveyor belt with adjustable speed

Die-cutting unit

• Electronic detectors, microswitches and photoelectric sensors throughout the machine are controlled by a programmable logic controller (PLC)
• Pneumatic locking system makes it easy to lock and release the cutting die and cutting plate
• Mechanical double-sheet control, a late-sheet detection device and an adjustable air blower ensure reliable and precise sheet transport.
• Pneumatic lifting of the cutting plate for easier insertion and removal
• A centring system on the cutting chase with diagonal fine adjustment ensures precise registration, allowing quick job changes.
• The side lays can be switched between pull and push mode on both sides of the machine simply by turning a pin, without mounting or dismounting any parts. This ensures flexibility in processing a wide range of materials, regardless of whether the register marks are on the left or right side of the sheet.
• Automatic error display and automatic diagnostics.
• Precise positioning of the cutting die is controlled by an accurate optical sensor with automatic checking and locking device
• Optical sensors with an automatic stop system on the feed table optimise the monitoring system for comprehensive quality control across the entire sheet width and in the event of a sheet jam.
• Cutting die turnover device
• Siemens main motor controlled by a Schneider inverter
• Fine adjustment of cutting force (pressure accuracy up to 0.01 mm, max. cutting pressure up to 150 tons) is provided by a servo motor with worm gear, controlled via a 15-inch touchscreen
• The crankshaft is made of chrome steel (40Cr).
• The machine frame and ram are made of ductile cast iron (HT300)
• 7 sets of gripper bars made of lightweight, durable aluminium alloy with an ultra-hard anodised surface ensure accurate and consistent sheet register
• High-quality gripper bar from Japan offers a long service life
• The perfectly designed gripper bar requires no compensation spacer to ensure accurate sheet register
• High-quality pre-stretched Renold chain from England ensures stability and accuracy for long-run jobs.
• High-pressure gripper bar register system ensuring accurate positioning
• Overload protection device and torque limiter ensure a high level of safety for both operator and machine
• Automatic lubrication and cooling system for the main drive and automatic main chain lubrication.

Stripping unit

• Triple-action movement structure with upper, middle and lower stripping frames driven by 3 cam wheels, which are more forgiving in long-term operation.
• It aligns with the centre line of the die-cutting section's chase locking system, minimising changeover time.
• Stripping pins or male/female stripping dies can be used for various stripping tasks.

Delivery

• An adjustable AC-motor-driven brake brush helps take paper from the grippers and stack it at higher speed with perfect pile alignment.
• Delivery pile height max. 1150 mm.
• Photoelectric device to prevent excessive rising or lowering of the paper pile.
• Sheets in the pile can be counted by an optical sensor (standard), and this unit can be integrated with a tape inserter for placing paper markers in the pile (optional), making it easier to remove unprinted sheets and pack.
• The entire machine can be set up via a 10.4-inch touch monitor at the rear.
• An auxiliary conveyor grid makes it easier to configure the machine as a non-stop delivery.

Electrical components

• Electronic detectors, microswitches and photoelectric sensors throughout the machine are controlled by a programmable logic controller (PLC)
• Omron electronic cam switch for encoder switching
• All main operations can be controlled via 15-inch and 10.4-inch touchscreen monitors
• PILZ safety relay, fitted as standard, ensures a high safety standard
• Internal interlock switch meets all CE requirements
• Electrical components including Moeller, Omron, Schneider relays, AC contactors and air circuit breakers ensure stability for long-run jobs.
• Automatic error display and automatic diagnostics
