Automatic Die Cutting and Stripping Machine

Main Component Configuration

Pre-Stack and Paper Feeding Unit

The pre-stack device supports continuous sheet feeding. The feeder uses a rotary air distribution system with four lifting suckers and four forwarding suckers to pick up and advance sheets.

Adjustable guides on both sides of the paper stack help align the material, while the inclined feeding table guides sheets toward the die cutting unit. The push and pull side lays can be adjusted independently, and the feeding table and belt speeds can be set to coordinate sheet arrival at the front lays.

Two independent front lays, a double-sheet detection device and feeder protection devices help maintain consistent feeding. The machine also supports non-stop feeding. Operators can check operating conditions and fault messages on the colour touchscreen.

Die Cutting Unit

A crankshaft-driven toggle mechanism moves the lower platform, while the reinforced upper platform supports the pressure required for die cutting. High-strength chains drive the gripper bars through the unit.

Operators can adjust die cutting pressure through the touchscreen. A torque safety clutch helps protect the indexing mechanism if a gripper bar is subjected to an external impact. The pneumatic chase lock and centre positioning system help operators align the cutting plate and chase during die changes.

A circulating oil cooling system helps limit pressure variation caused by temperature changes during operation.

Stripping Unit

The three-chase stripping unit removes waste after die cutting. Its centre positioning system helps align the stripping tooling, while adjustment devices simplify the positioning of the upper and lower stripping pins. This makes setup more manageable when changing jobs.

Paper Delivery Unit

The automatic curtain-style delivery unit supports non-stop sheet collection. Adjustable delivery brushes and a lower air blow device guide finished sheets into the pile for orderly delivery.

The chain movement is designed to reduce wear and operating noise. A safety device also helps prevent the delivery platform from pressing against an operator’s foot.
