Slitting machine technology introduction Corresponding to the vertical direction of cardboard corrugation, vertical slitting machine is mainly in accordance with the paperboard longitudinal slitting, trimming, and indentation of the rolling slot at the press-folded place (as shown in the following figure, the red line is single The flaps in the box and the indentations in the box height, the blue lines on the edges are the cuts between the multiple pieces, and the products that are produced are folded and pasted to become the packing cartons we use every day. Slitting generally takes the form of a single blade (thin knife). The indentation is rolled up and down using male and female rollers. The method of adjusting the cutter and the roller can be divided into manual adjustment and full computer adjustment. A typical carton presses four-cornered quadrilaterals. Of course, some packages require five or more presses, which can stack up into cubes, hexagonal cubes, and even more cubes. According to the maximum number of cuts, the slitting machine is further divided into 7-knife, 12-thread, 6-knife, 10-line, 5-knife and 8-wire models. Several knives represent the maximum number of pieces of paperboard that can be cut into pieces, and the press rolls The number is (2* the maximum number of -2). According to the slitting machine used in different occasions, the process is different, but the core process is basically as follows The main process 1. Order management function: edit, save, display, automatically update the order to be processed, and determine whether the order is a legal order when the user edits the order. If the order is not legal, it will not be saved and an error message will be given. 2. Auto change/single order function: According to the order specification, it automatically arranges the slitting knife, the pressure reel and lifts the corresponding slitting knife, the pressure reel, and automatically switches the press type. When the upper computer (touch screen, production tube microcomputer) sends an incorrect order, it automatically detects whether there is a knife/line, and if not, it does not send it to the system. Auxiliary process 3, sharpening, lubrication function: the knife will wear after long-term use, need to repair it; 4. Deviation correction function: correct the edge of the paper or correct the color mark according to the position of the paperboard sent from the previous process; 5, pre-pressure depth adjustment function: By adjusting the position of the pressure roller to adjust the pressure line depth; 6, waste collection function; 7. Perfection of alarms and exception handling: It is mainly to ensure operator safety and reduce the damage rate of the device itself; 8. Factory-level production line management: It is required to be able to access the factory cadre production line management system and centralize control. Slitting machine main acceptance index 1, the finished cardboard cutting size is not accurate, the required precision of ± 0.5mm; 2. The quicker the better the single row time, the faster the time for platooning, and the less the waste generated from the corrugated cardboard production line, the higher the production efficiency. 3, cardboard can not be displaced during cutting and indentation; 4, the system is stable, safe and reliable. The stable and reliable system mainly reduces waste production and production efficiency; 5, whether the pressure line is broken and the appearance of the incision is smooth and beautiful. Introduction to several generations of the development process of slitting machine The main process Kinco Complete CANopen Solution Block Diagram Scheme notes One: Due to different customer needs, this program only contains the cutter, control line pressure control part, the scene set the display unit, reserved production management interface, etc., does not include correction, grinding, suction waste, input and output control section; Two: Due to different customer needs, the number of cutters and crimping motors in this program is different. Kinco Complete CANopen Solution Features 1. The system's full set of CANopen bus control solves the problems of the large number of wirings caused by the pulse control method, the inaccurate positioning accuracy due to loss of pulses, and the poor anti-interference ability, high control accuracy and high cost performance 2. The system adopts Bustronics F1 series bus type PLC control with high degree of automation. The software adopts the European mainstream software - Germany 3S Codesys software. Its CPU frequency is up to 800M, and the program execution precision is 1ms, which ensures the efficiency of the single row; 3. The system comes with two isolated CAN bus interfaces, all the way to control the cutter and the crimping motor, all the way to control the cutter and the pressure line inverter, which overcomes the disadvantages of the traditional industry's variable frequency analog control instability, low accuracy, etc. Ensure that the inverter runs independently and reduce the interference to the system; 4. The system reserves industrial Ethernet interfaces, supports standard Modbus TCP/UDP protocols, and facilitates access to the factory production management of the cadre production line. It also supports serial access to the production management system. 5. Since the system uses bus control, software and hardware are easy to maintain and easy to expand. For example, all-motor control series slitting machine can be integrated into one from 5-knife 8-wire to 7-knife and 12-wire. The hardware only needs to increase or decrease the corresponding knife-line motor system. Kinco Complete CANopen Solution Configuration
