This machine is required to realize high efficiency and high yield for the corrugated cardboards. Its main functions are: 1. Cut off waste boards and papers prior to order change, which can provide guarantee for non-stop order changing; 2. It can realize the non-cutoff order change for double layer production line 3. It will cut the wastes and stop when there is machine malfunction.
Electric and pneumatic parts
Electric and pneumatic parts:
Cutoff control: British CT AC servo controller or LENZE servo
Operation monitoring: Schneider touch screen Monitoring
control: Schneider PLC or LENZE PLC、 PEPPERL FUCHS
proximity switch, optoelectronic switch, SICK encoder.
Low voltage apparatus: Schneider
The equipment adopts cutting anvil roller，which uses separate driving structure for the lower and upper
motors to enable the load of the motors to be reduced by half compared with non-separate driving structure.
The blade roller could be synchronized with production line instantaneously. It is necessary when the order is
changed without slowing down or malfunction cutoff. The speed of cutting waste could be 220m/m. (The speed of
production line is 250m at extremity);
Long service life
The upper and lower knife roller are driven by servo motor separately. Due to different diameter of the anvil
roller and knife roller, each cutting position will be evenly distributed on anvil roller.
Comparing with the structure of one motor driving (cutting the same position), the anvil roller could serve much
longer service life which will be more than 6 million times.
Arrangable multi-blade system
The entire blade roller is made by many groups of blades in sequence and each could be controlled for ascent
or descent independently. It can connect with the production management system to control the positions where
to cut or not during the boards cutting. So it can carry out the function of order changing without cutting off the
boards and do the edge cutting for double layer production line.
Fast and smooth waste discharge
The upper and lower belts are powered to discharging the boards without blocking.
