Specification:

☆ Feeding unit

l Feeding method
Four shaft wheel type lead edge feeder;
Mechanical feeding system, feeding speed display on touch screen;
Bottom vacuum suction to help high feeding precision and vacuum force controlled by frequency inverter. For different bending degree board, use different vacuum force, save energy;

l Sheet stop adjustment
Electric adjustment of the left & right sheet stop;
Rear stop moving and lifting adjusted by hand;
Front stop adjusted by hand, dial display adjustment distance;

l Feeding roller
Top roller is rubber roller, provide light pressure and high force of friction to corrugated sheet, can prevent sheet surface damaged;
Rubber feeding roller is done with dynamic balance test;
l Control panel
Emergency stop button installed;
Control panel with buttons for: main motor start/stop, speed up/down, Vacuum force increase/down, skip feeding, auto counter;


Die cutting part

• Machine body thickness
  Body thickness: 50mm

• Anvil cylinder
  Material: seamless steel tube
  Outside diameter: 434.2mm
  Thickness:25mm
  Surface coated hard chromium and do dynamic balance test and static balance test;
  Mechanical helix moving structure to make anvil cylinder can do lateral excursion with 40mm range;

• Speed Differential Compensation function
  The speed differential compensation function can keep surface linear speed of anvil cylinder always as die cutting cylinder. It make the surface linear speed of anvil cylinder controlled by die cutting cylinder, so that can make sure high accuracy die cutting.

• Anvil cover
  Thickness: 9.4mm
  Width of each piece: 250mm
  Inside diameter: 434.2mm
  Brand: Maxdura, CDG

• Anvil cover repairing device
  The repairing blade is installed for cutting the worn part of the anvil cover, so that it can increase the working time of the anvil cover;
  Customer can select the blade working after die cutting fixed times;

• Die cutting cylinder
  Material: Seamless steel tube
  Outside diameter: 410mm
  Thickness: 30mm
  Die amounting holes diameter: 10mm, use screw of size M10
  Holes center distance: 100mm in horizontal direction
  Holes distribute on circle: 18 holes with uniform distribution on circle
  Surface coated hard chromium and do dynamic balance test and static balance test;

• Regulation of die cutting cylinder registration
  Gear box reducer for locking the registration position;
  Planet gear system is used;

• Pneumatic lift device
  When no need die cutting, the die cutting cylinder can lift the anvil cover cylinder, driven by pneumatic cylinder. This can save energy consumption and protect the anvil cover and prolong its working time;

• Control panel
  Units open/close control button
  Units pneumatic locking button
  Die cutting registration control button
  Emergency stop button is installed;
