This machine adopts suction belt for feeding paper. It has the function of slitting and pressing at one time. The standard model is four knives and six lines. The power of this machine is divided into three parts. The first power motor is the belt paper feeding part, which adopts variable frequency speed regulation. To control the speed of paper feeding time, the second part of the power motor is the paper slitting and line pressing part. The frequency conversion speed regulation can make the paper slitting speed adjustable, and it is used at a differential speed with the paper feeding motor speed. The third part of the motor is a suction paper feeding motor. When the cardboard is too large or warped, the suction fan is turned on to make the maximum area of the cardboard contact the paper feeding belt to achieve smooth paper feeding. The pressure of the paper feeding shaft and paper separation shaft are all mechanical and manual. Adjust, the upper shaft pressure rises and falls by twisting the pressure handle, and the pressure is adjusted in a coordinated and balanced manner on both sides.
