Structural logic description The schematic diagram on this page is redrawn according to the common structure of the slitting machine.The mother roll is located at the rear unwinding rack, the center completes deviation correction, traction and knife group slitting, and the front is the biaxial rewinding and unloading area to avoid mistaking the equipment as a rewinder or laminating machine.
Overview

Standardized slitting machine page for coil processing scenarios

It is suitable for display in the product center of the official website to introduce the structural logic, core capabilities, technical parameters, control system, applicable materials and selection suggestions of the slitting machine. The page content has been rewritten according to the logic of "slitting machine" instead of "rewinder/laminating machine".

Rear unwinding

The mother roll is installed at the rear of the equipment to facilitate the formation of a more reasonable material path. It is clearly separated from the host slitting area and the front rewinding area. The structural logic is more in line with the application of high-speed slitting machines.

Round knife high speed slitting

It adopts a circular knife slitting mechanism, suitable for film, self-adhesive, PVC, OPP and other rolled materials, taking into account edge cutting quality, speed and knife adjustment efficiency.

PLC centralized control

Touch screen parameter setting, combined with tension, deviation correction, speed and meter counting control, improves order change efficiency and equipment operation stability, and lowers the operating threshold.

Biaxial slip winding

The double-axis winding is equipped with a slip shaft, which is suitable for simultaneous winding of finished products of multiple specifications. The winding ends are neater and the tension is more uniform. It can be equipped with an automatic unloading device to improve efficiency.

Process

Slitting machine structure process

From the roll material entering the equipment to the formation of the finished roll, the typical process consists of rear mother roll unwinding, automatic deviation correction, traction and tension stabilization, circular knife slitting, biaxial winding and unloading.

Key structure description

If it is an official website product page, the structural description should allow customers to understand the equipment logic at a glance, especially to avoid mistakenly drawing "master roll unwinding" into the front rewinding area.

Rear unwinding
The parent volume can only be at the backAs the input end of large roll raw materials, it is usually arranged at the rear of the main machine. This makes it easier to organize the material path and is more in line with the actual structure of the high-speed slitting machine.
Host center
Traction, tension and knife groups are concentrated in the middle of the main machineDeflection correction, traction, tension control and slitting knife groups are usually concentrated in the middle of the main machine, which is the core area of equipment performance and accuracy.
Front rewind
The finished roll is formed at the front endThe dual-axis slip rewinder is located at the front, making it easier for the operator to observe the roll end, adjust the finished roll, and dock the automatic unloading function.

Modules

Core functional modules

The product page of the website does not need to pile up all the parts one by one. It is more suitable to use a "modular" method to clearly explain the equipment capabilities, which is both professional and easy for customers to understand.

01

Rear hydraulic shaftless unwinding

It supports the loading of raw materials with large roll diameters, which is suitable for improving the efficiency and stability of roll changing. Combined with the post-unwinding structure, it is more conducive to smoothing out the material path.

  • The mother roll is located at the rear of the unit
  • Can be equipped with automatic correction
  • Can detect residual roll diameter and decelerate to stop
02

Automatic correction and tension control

The deviation correction controller and tension control system keep the edge position of the material stable, reduce snakes and wrinkles, and improve the reliability of high-speed operation.

  • Total deviation correction stroke 150 mm
  • Tension automatic control mode
  • Improve finished product consistency
03

Servo traction system

The traction servo is used to drive the main traction roller, which runs more smoothly and is suitable for high-speed and precision slitting applications.

  • Typical configuration: 7.5 kW traction servo
  • Fast response
  • Conducive to stable material feeding
04

Round knife slitting knife set

It is suitable for rapid slitting of multiple specifications of film, labels and other roll materials, taking into account speed, edge quality and convenience of adjustment.

  • Circular knife slitting structure
  • Slitting width 50–1300 mm
  • Cutting accuracy ±0.2 mm
05

FAQ

Common selection questions

Why does the slitting machine page emphasize "the mother roll is at the back"?＋
Because this is one of the most intuitive points for customers to identify device logic. The mother roll belongs to the raw material input end and is usually arranged at the rear; the front is the area where winding and operations are more frequent. If the position is reversed, professional customers will see at a glance that the structure is incorrect.
Is it enough to show the top speed on the website?＋
Not enough. It is recommended to also state "depends on the material" and display the cutting accuracy, tension control, roll diameter range and finished product width range, so that the information is more complete and more real.
What roll materials are suitable for slitting machines?＋
Typical examples include PET self-adhesive, BOPP, CPP, PVC, OPP, paper, protective film, tape and some functional materials. The final configuration still needs to be confirmed based on thickness, surface properties and finished product requirements.
What information is required before selecting a slitting machine?＋
Confirm the parent-roll material, thickness, maximum width and diameter, core size, target slit widths, finished-roll diameter, speed requirement, winding quality and available floor space.
