Talking about the working principle of A4 paper cutting machine

A4 paper cutting machine is a paper processing equipment that cuts and rewinds wide webs into rolls of different widths and diameters. Widely used in paper processing industry or mechanical equipment before and after printing.

The main structure and working principle of A4 paper cutting machine:

The A4 paper cutting machine consists of a frame, a transmission system, a retracting and unwinding machine and a tension control device, a traction component, a slitting bracket, and a waste rewinding and discharge device. It divides the raw material into several independent units. Its working principle is to fix the raw material on the unwinding. One end of the unwinding shaft is equipped with a magnetic powder tension controller to constant the tension of the raw material, and then it is pulled by a pair of rubber rollers. The raw material is cut into several strips by the blade. Then it is guided by each guide roller to A and B winding shafts to wind the finished product. Its transmission is driven by the main motor to drive the traction rubber roller and the rewinding shaft to run synchronously to achieve the purpose of traction and material rewinding.

1. A4 paper cutting machine frame and transmission system: the frame is composed of left and right wall panels, supporting blocks and unwinding machinery. The transmission system is mainly used to pull raw materials and wind finished products. It is driven by a variable frequency stepless speed regulation motor. The power makes the traction rubber roller run through the motor V-belt, the main traction rubber roller and the driven traction rubber roller are close to each other and run synchronously to pull the raw materials, and the active traction roller drives the lower round knife shaft to operate synchronously to achieve better cutting requirements. , Rewinding A and Rewinding B are driven by the lower round cutter shaft to perform synchronous operation, so as to achieve the purpose of rewinding.

2. A4 paper cutting machine rewinding mechanism and its tension device: the rewinding mechanism is mainly composed of chains, synchronizing wheels, magnetic powder clutches, and air expansion shafts. It is controlled by a single motor to control the operation of two rewinding shafts, as long as the magnetic powder is adjusted The current of the clutch can change the tension of the rewinding shaft.

3. A4 paper cutting machine traction component: the traction component mainly consists of a pair of traction rubber rollers and a number of hard oxidized aluminum rollers, which are used to retract the raw materials for the winding of the finished product. Its power comes from the motor passing through the V-shaped The belt is passed to the active traction rubber roller to make it run.

4. A4 paper cutting machine slitting knife holder: the slitting knife holder has round knife slitting, straight knife slitting, and the operating handle can make the round knife move slightly in the axial direction through the plane cam to adjust the round knife edge and the cushion cover. Shear gap of the groove.

5. A4 paper cutting machine waste material rewinding and discharge: waste material is discharged through the air duct using the wind of the blower.

6. A4 paper cutting machine unwinding mechanism and automatic deviation correction: the unwinding mechanism mainly consists of unwinding shaft, support block, cylinder, base, left and right moving seat, etc. Automatic correction device: with photoelectric head, correction guide roller, left and right support, correction It consists of moving plate, ball nut and screw rod, synchronous motor and left and right limit switches.
