Today's corrugated paper cross cutting machine is mainly divided into mechanical knife and computer knife. From the control system, computer knife is divided into DC system and AC frequency conversion system.
So more and more customers want to change their mechanical knife into AC servo control knife.
The cost of this change is ¥32,0000.00.
With a 1.6 meter width watt line, a monthly production value of ¥5000000.00 and an electricity fee of ¥1.00, the production cycle is calculated every day for 8 hours:
A) The cutting accuracy of the mechanical knife is +/- 5MM or more, the cutting accuracy of the computer knife is +/- 1~2MM, the average cardboard length is 1200MM, and the side increases the cutting accuracy by one monthly cost savings:
Output value *accuracy difference / average board length = output value *0.005 = ¥ 25000.00
B) The power consumption of the double-sided machine of the 1.6-meter mechanical knife is about 25KW/H, while the power consumption of the double-serve and cross-cutting machine of the AC servo computer knife is only 10KW/H or less, and the production is calculated every day for 8 hours. The monthly electricity fee is:
(25-10)×8×30×1.00=3600.00
C) mechanical knife cutting accuracy is +/-5MM, the general production speed can not be greater than 80 meters / minute, while the AC servo frequency conversion computer knife production speed can reach 100 to 120 meters / min, coupled with its quick change orders. This greatly improves the production efficiency, and also reduces the heating, pressurization, and transmission energy consumption of single-sided machines, gluing machines, and double-sided machines.
Based on the above, the investment in retrofitting the crosscutting machine can be recovered within one year.
Above is sheeting unit inline with corrugated making machine.
If single-faced corrugated paper sheeting machine, please check our RS-D 1400 rotary blade sheeting machine. It can work separately, which is more flexiable and easy to change cutting size. This automatic sheeting machine also could cut cardboard paper roll into sheets as well.
