3. Work Efficiency
The primary factors that determine the slitting efficiency is the operating speed. The higher the speed, the higher the yield per unit time. From these factors, the higher the speed is better. But the higher operation speed of the slitter, the higher requirements of the equipment. First, the device's accuracy requirements, the more complex mechanism apparatus; secondly, the higher the precision control of the equipment, the more complex configuration, the higher grade, the higher final price of the slitting equipment. According to the current market, a width of 1300 mm, the speed at 150 ~ 200 m / min of Kingsun Machinery Slitter rewinder, price is USD15,000 ~ 22,000; the same size, the speed at 300 m / min or so, slitting machine for $ 40,000 to 50,000; and the same size, speed 400 m / min Kingsun slitting machine, priced at $ 70,000 to 10 0000. Moreover, high-speed slitting machine during operation, print quality defects can’t be detected. Therefore, not all company need the highest grade of high-speed slitting rewinding machine, but it should be based on specific demand, choose the most suitable slitting converting equipment.
The second factor in determining the efficiency of the operation is effective rate of slitter rewinder, that is, normal working hours ratio of equipment uptime plus downtime. According to the working principle of slitting machine, rewinding slitting, the unwinding is a single work station, it is difficult to achieve non-stop for slitting, must be shut down to change the rolls. Retractor roll quantity, the more discharge rolls, the longer the time it takes to install the paper core. Under normal circumstances, the finished length of flexible packaging material in 1 200 ~ 2 000 m, if you choose a speed of 300 m / min of slitting machine, the time required for 5 ~ 7 min; If you use a higher speed slitter required operating time is shorter. According slitting scene, the time for each roll you change takes 2 ~ 4 min, ie, the effective functioning of the equipment rate of 60% to 80%, the thicker the material, the finished width is smaller, the effective functioning of the equipment with lower rate.
In order to improve the effective functioning of the rate of the equipment, some of the high-speed slitting machine equipped with automatic unloading equipment and paper tube positioning device. Automatic unloading device after rewinding diameter to reach the requirements, with a special material unloading device will receive the two-axis roll once removed, will not only reduce the operator's labor intensity, but also shorten the time of discharge. Paper core positioning device is mechanical or photoelectric way cylinder core fixed position, avoid feeding tube core and the film of the incorrect position, according to the material at the beginning of the film to start correcting cylinder core functions, shortening the unloading time, tube loading preparation time, thereby increasing the effective operation rate of the slitting rewinding equipment.
