The price of paper has skyrocketed, and this technology has helped you to reduce the loss of raw paper!
Corrugated board production line cadre exchange order can save raw paper loss through zero loss replacement technology
At present, the form of the single-knife change of the cadre of the corrugated board production line is divided into: a gap change order and a gapless change order.
1, there is a gap change order:
There is a gap change process is to use the cutting machine, cut the cardboard, pull the cardboard, the slitting machine drags the knife to change the order, cuts the head of the upper tail and the order by the cross cutter (to find the cutter reference), and simultaneously The tail and head loss, generally the tail and head length is 400-800mm. The speed of changing the order is to speed up the exchange of orders, which is easy to cause the last few lengths of the cardboard, and shake the head and tail.
2, no gap change order:
The process of changing the gap without gap is that the cutting machine does not cut the cardboard, but cuts the trimming joint with an ear knife, the cutting machine boring tool changes the sheet, and the cutter is cut by the cross cutter to change the knife and the line position part, and at the same time Cut off some of the loss, the general length is 600-800mm. There is no gap change, and there is a gap to change the single speed. The faster the change speed, the longer the cut length. There is a gap change on a single tail size plus a single head size of about 300mm-400mm.
3, zero loss for a single:
The process is consistent with the process of changing the gap. The high-precision laser (laser) measuring instrument controls the cutting machine to cut off the line on the upper single line accurately. The error is evenly distributed on the last few sheets by precise measurement and control. The measurement also does not require a cutting head to set the reference, so that the replacement is zero loss. Zero-loss replacement, for domestic small order structure, can significantly reduce losses.
4, loss comparison:
The average loss of a single order in China is 0.8 meters. Assuming an enterprise produces 500 orders per day, the average door width is 2 meters, and the average weight is calculated as 550 grams per square meter. Then the loss per day is 0.8 meters × 500 orders. × 2 meters = 800 square meters. One square meter is calculated according to 0.55 kg, then the loss per day is 800 square meters × 0.55 kg = 440 kg. If the production is 30 days per month, the loss will be 0.44 tons × 30 days = 13.2 tons.
If the latest technology of changing the single zero loss is adopted, the loss of the original paper can be saved in one year: 13.2 tons × December = 158.4 tons, which can save money: 158.4 tons × 3,000 yuan / ton = 475,200 yuan.
