Chain-drive feeding Rotary die-cutting machine

Die-Cutting Machine

Rotary die-cutting machine

Function and characteristics:

1.Whole wallboard and important components are adopted aging treatment, eliminate the metal internal stress; Adopt high precision machining centers, CNC grinding machine for grinding processing.

2.The machine shaft, roller are adopted high quality steel, grinding processing, high precision computer dynamic balancing correction and surface hard chromium plating.

3.The engine drive gear is adopted 45# steel.

4.Machine transmission parts (shaft, gear joint) are adopted free key connection (LOCK-ALX), the connection eliminate clearance. It is suitable for long-term high speed running with high torque.

5.The machine drive bearing ,important driving parts adopt three big domestic famous brand: Hava los, simple maintenance, long service life.

6.The engine lubrication system is adopted automatic spray type lubrication.

Feeding part:

1.Cardboard dimension adopts guide screw adjuster, easily and quickly；

2.Adjustable worktable, suitable for every kind paperboard;

3.Feeding paper adopts rubber seamless leather belt, big frictional force; long working life; low noise; easy maintain;

4.Double tension control device, easily and reliable;

5.Transmission roller adopts engraved roller, increase the frictional force with the belt, guarantee the feeding smoothly.

Die-cutting part:

1. Die cutting roller:   

1)Centrifugal casting steel cylinder, the computer dynamic balancing correction, surface       grinding, hard chromium plating, and increase the running stability.   2)Die cutter fixed screw holes spacing of 100 * 100 mm  

3)Apply to cutting die height 25.4 mm  

4) die cutting roller diameter :432mm (without the wooden die )  

5)Die-cutting roller cylinder type auto separation unit,  it can up and down by       pneumatic ,and delay time ,there is photoelectric, so when the paperboard through ,     then the die cutting roller will lift up , decrease wear of rubber. 

2.  Rubber roller :     

 1)Cast steel material, surface grinding, hard chromium plating 

 2)Balance correction, increase the running stability  

3)rubber thickness is 10mm , width is 230mm or 250mm  

4) rubber roller diameter is 434.2mm(without the rubber)  

3. Horizontally move ,repair device :   

1) Mechanical horizontal 40 mm move device, die-cutting uniform linear speed automatic  compensation of weighing, can make the die cutting rubber even wear,      prolong service life. 

2)Repair the use of electric repair device, improve the rubber repeat utilization rate, can repair 3-4 times.  

3).Linear speed automatic compensation, to ensure that each batch of carton die-cutting size exactly.

4. other details :

1).Six levels of fine grinding gear using 40cr material, low noise, long service life.

2).Lubrication system, adopting the mechanical pump oil supply device, automatic spray the  circulating oil, lubricate evenly, improve the service life of gear.

3).phase adjustment is by electric.
