Working principle of automatic slitting machine

As the degree of mechanization becomes higher and higher, the requirements for the efficiency of winding operations are also higher and higher. When the slitting machine is used in the slitting operation of film, tape, and paper, it can cut the whole roll of a large reel into multiple small reels according to different requirements to meet the needs of different occasions. The industry has a wide range of applications.

Working principle of automatic slitting machine

The automatic slitting machine manufacturer tells you,the raw material is fixed on the unwinding shaft, and one end of the unwinding shaft is equipped with a magnetic powder tension controller to keep the required tension of the raw material, and then The raw material is pulled by a pair of rubber rollers, and cut into several strips by the sewing sheet. Guided by the grid guide roller to the A and B rewinding shafts for rewinding the finished product. Its transmission is driven by the main motor to drive the rubber roller and the receiving shaft to run synchronously to achieve the purpose of pulling the material and receiving the finished product.

Introduction to the components of the automatic slitting machine:

The paper slitting machine is composed of a frame, a transmission system, a feeding and unwinding mechanism, a tension control device, a traction member, a slitting support, a waste winding and discharging device, etc. It is to cut the raw material into several independent units.
1. Frame and transmission system: The frame is composed of left and right wall panels, supports, and unwinding machinery. The transmission system is mainly used to pull raw materials and rewind finished products. It is driven by a frequency conversion stepless speed regulating motor through the motor V The type belt makes the traction rubber roller run, and the main traction rubber roller and the driven traction rubber roller are close to each other and run synchronously to drive the raw material to walk. The active traction roller drives the lower circular knife shaft to run synchronously to achieve better cutting requirements. The cutter shaft drives the rewinding A and rewinding B to run synchronously, so as to achieve the purpose of rewinding.
2. Rewinding mechanism and its tension device: The rewinding mechanism is mainly composed of chains, synchronous wheels, magnetic powder clutches, and air expansion shafts. A separate motor controls the operation of the two winding shafts. As long as the current of the magnetic powder clutch is adjusted, The tension of the receiving shaft can be changed.
3. Traction member: The traction member is mainly composed of a pair of traction rubber rollers and several hard oxidized aluminum rollers, which play the role of drawing raw materials and walking for finished product winding. Its power comes from the motor transmitted to the active roller through the V-belt. Pull the rubber roller to make it run.
4. Slitting knife frame: The slitting knife frame has circular knife slitting and straight knife slitting. The operating handle can make the circular knife make a small amount of axial movement through the plane cam to adjust the cutting between the circular knife edge and the groove of the cushion sleeve. gap.
5. Waste rewinding and discharge: Waste is discharged through the air duct using the wind force of the blower.
6. Unwinding mechanism and automatic deviation correction: The discharging mechanism mainly consists of a discharging shaft, a support block, a cylinder, a base, a left and right moving seat, etc. The automatic deviation correction device consists of a photoelectric opening, a deviation correction guide roller, a left and right bracket, a deviation correction moving plate, and a ball Composed of nuts and screw rods, synchronous motors, and left and right limit switches.

Application range of automatic slitting machine:

1. It is used for slitting paper types, which is also the mainstream product packaging market in the current packaging equipment, which is often seen.
2. It is used in industries that require slitting of leather, cloth, plastic, film, etc.
3. Used for slitting metal coils such as slitting strip steel, stainless steel, copper... It is mainly used for steel processing plants, fixed steel market operators, rolling mills, electrical industry, automobiles, stamping parts, etc.
