When the slitting machine’s central machine arranges orders, it will make RS422 communication with computer base plate through the communication convert card. Computer base plate sends control order to driving output circuit, and then the transmission mechanism drives the related cut-off knife, line pressing wheel to the scheduled position. Mechanical scale is fixed under both cut-off knife and line pressing wheel to correct the position.
1.If slitting machines is in high-precision to paper plate cutting and line pressing, the number of position should be accurate firstly. Secondly it needs a position of high resolution ratio and high sensitivity to test rotary encoder. Besides that, it should be guaranteed by reliable communication mode. In general, the communication mode of RS422 or RS485 should be taken to improve the ability of anti-jamming and to guarantee the accuracy of slitting the plate in the long distance.
2.The correcting function of central computer: In order to guarantee the accuracy of boarding cutting line pressing, it is necessary to correct it every day which should be involved in slitting machine.
3.For the reason that the position of plate is easy to change, and we should guarantee the perfect cutting of plate board, and the shift adjustments crosswise.
Slitting machines’ affection on the appearance of paperboard The cutting knife quality, adjustment status of cutting knife, kind of line pressing wheel can affect the quality and appearance of the paperboard. Nowadays, many carton enterprises are all use 1mm thin edge slitter to get rid of the disadvantages of deckle edge, flatten, fissure and so on. Cutting thin knife can not only affect appearance, but also the cost of production. The line pressing wheel’s linear velocity should more than 3% the velocity of board’s operation which can be adjusted alone to guaranteed the clean and good-looking of the cutting edge. In addition, in order to prevent dry paperboard’s cracks from line pressing, the preliminary line pressing wheel device will be fixed.
Some useful tips of maintaining slitting machines
The maintenance of sheet metal slitting machine plays an important role, we should guarantee lubrication of machine screw and bearings. In the first place, we should make sure that sliding parts are in good condition. Secondly, regular adjustments, changes are needed, and we should record them in detail in order to extend the life of equipment. Last but not the least, the operator’s technology and quality should be improved.
