Paper Slitter

Paper Slitter

Paper slitter is a paper trimming equipment that slits and rewinds wide web into the rolls of various widths and diameters. As a paper slitting machine, it is widely used in the paper making or printing industry.

Main structure and working principle

Paper slitter is composed of a frame, a transmission system, a feeding and discharging machine, a tension control device, a traction member, a slitting bracket, a waste winding and a discharge device. It is to divide large paper web into several independent rolls. The working principle is to fix the web on the end of the discharge shaft equipped with a magnetic powder tension control to keep constant tension required by the web, and then towed by a pair of rubber rolls. The web will be cut into several pieces by a blade. Then, the guide rolls are guided to the A and B winding rolls to wind up into the finished product. Its transmission system is driven by main motor to drive the rubber rolls and the receiving shaft to run synchronously to achieve the purpose of paper traction and the finished product receiving.

  1. Bracket and transmission system: Bracket consists of left and right walls and supporting and discharging machinery. The transmission system is mainly used for pulling materials and winding the finished product. It is powered by the variable frequency stepless speed regulating motor. The belt makes the traction rubber roll get running. Main traction rubber roll and the driven traction rubber roll are attached closely and run synchronously to pull the materials to move, and the active traction roll drives lower circular cutter shaft to operate to achieve better cutting requirements synchronously, and passes through lower circle. The circular cutter shaft drives the A winding and the B winding to perform synchronous operation, thereby achieving the purpose of receiving the material.
  2. Receiving mechanism and tension device: The receiving mechanism mainly consists of a chain, a synchronous wheel, a magnetic powder clutch and an air-expansion shaft. Two rolls are controlled by a single motor. As long as the current of the magnetic clutch is adjusted, the tension of the receiving shaft can be changed.
  3. Traction members: The traction members mainly consist of a pair of traction rubber rolls and a number of hard oxidized aluminum rolls, which are used to take the materials for the winding of the finished product. The power is derived from the motor passing through the V-belt to the active rubber rolls to make it run.
  4. Slitting holder: it has a circular slitting blade, a straight slitting blade, and a moving handle.
  5. Waste rewinding and discharging: The waste is discharged through the wind pipe using the blower.
  6. Discharging mechanism and automatic rectification: The discharging mechanism mainly consists of a discharge shaft, a support block, a cylinder, a base, left and right moving seats, etc. The automatic rectification device mainly consists of a photoelectric opening, rectification guide rolls, left and right brackets, a rectification moving plate, synchronous motor and left and right limit switches.

Performance and features

  1. Paper slitter adopts PLC and touch screen control, magnetic powder clutch type tension control and center winding method.
  2. The host is using frequency control, automatic metering, alarm shutdown, tension digital display on the touch screen.
  3. Discharging adopts photoelectric automatic rectification (or ultrasonic rectification) to correct the neatness of the paper, so that irregular materials can be cut normally.
  4. Circular blade (or straight blade) slitting, automatic waste discharging device.
  5. Manual (or pneumatic) charging. The discharging roll is equipped with a sleeve-type inflatable shaft (3〞or 6〞).

In order to make the machine work normally and slit high-quality finished products. And the condition of each part of the machine shall be checked from time to time and oiled with lubrication at each point.

Working environment

The working environment is used directly affects the performance and service life of the electrical appliances and components. The working environment of paper slitter should:

  1. Be installed in the room with good ventilation;
  2. Work at ambient temperature of -10°C + 40°C;
  3. Try to avoid high temperature and humidity of less than 90% RH with no rain dripping;
  4. Avoid direct sunlight;
  5. Stay without flammable, corrosive gases and liquors;
  6. Be installed with fixed base without vibration;
  7. Have no electromagnetic interference, and be away from interference sources.

Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibres from wood, fiber crops, waste paper, or rags. Many kinds of paper are made from wood with nothing else mixed into them. This includes newspapers, magazines and even toilet paper. Pulp is one of the most abundant raw materials.

A pulp mill is a manufacturing facility that converts wood chips or other plant fibre source into a thick fibre board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements.

A paper machine (or paper-making machine) is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.

The pulp produced up to this point in the process can be bleached to produce a white paper product. The chemicals used to bleach pulp have been a source of environmental concern, and recently the pulp industry has been using alternatives to chlorine, such as chlorine dioxide, oxygen, ozone and hydrogen peroxide.

Chemical pulp is produced by combining wood chips and chemicals in large vessels called digesters. There, heat and chemicals break down lignin, which binds cellulose fibres together, without seriously degrading the cellulose fibres. Chemical pulp is used for materials that need to be stronger or combined with mechanical pulps to give a product different characteristics. The kraft process is the dominant chemical pulping method, with the sulfite process second. Historically soda pulping was the first successful chemical pulping method.
