Slitting Machine Straight Knife Slitting Introduction

The main advantages of the slitting machine straight-knife cutting product are: reasonable structure layout, convenient operation, high degree of automation, high production efficiency, high work accuracy, and wide application range. At present, a straight knife slitting machine can be used to process various cold-rolled, hot-rolled coils, silicon steel plates, stainless steel plates, color plates, aluminum plates and various metal materials after plating or painting.

Refer to the following for the maintenance requirements of the hydraulic system of the slitter straight knife slitting equipment:
1. The fuel tank is well sealed and dustproof, or a breathing hole with an air filter is installed;
2. The hydraulic system of the slitting machine equipment must be equipped with a filtering device to remove contaminated particles in time. It is best to use a filter with an indication signal.
3. In the automatic slitting machine, the pressure of the oil pump should be adjusted to the minimum working pressure under normal working conditions to reduce energy consumption and prevent the oil temperature from becoming too high.

 In practical applications, because slitting equipment is used to cut the entire roll or the entire raw material at a fixed length, such as plastic packaging materials, packaging cartons, steel plates, films, leather, and wood chips Use fixed length slitting control. Fixed length slitting control is divided into static and dynamic slitting.

 For the slitter straight knife slitter, in actual work, the most important performance index of fixed length slitting is slitting accuracy, and the consistency of the finished length is good. The cutting length can be set continuously. If there is an error in the actual cutting length, it is easy to calibrate by setting parameters.

The split machine equipment is actually a machine, electric, hydraulic, and integrated equipment that cuts a wide strip of steel material into narrow strips according to specifications. It is used to cut the strip to the required width. The electrical system of the split unit is mainly used to control each motor, hydraulic system and pneumatic system of the unit. The entire electrical system is based on a PLC programmable controller, with an intuitive human-machine interface and high-precision, high-performance S120 variable-frequency speed control system and other AC drive controls and various detection sensors.

First of all, let's briefly understand the main application of the slitting unit. In the process of using this equipment for longitudinal shearing, it has obvious advantages, including convenient operation, high cutting quality, high material utilization, and stepless speed regulation of cutting speed. In fact, the equipment is mainly composed of unwinding (unwinding) ), Material positioning, slitting and slitting, coiling (rewinding), etc.

Based on the analysis of the actual production situation, the main production process of the slitting unit can be summarized as: preparation of rolls → roll up → unwinding → shovel head, straight head → pinch, leveling → centering (double-row vertical roller) → shear Cutting head and tail (transverse cutting) → centering (double-row vertical roller) → slitting (disk cutting) → looper → steel strip separation and tension control → waste edge coiling → coiling → unwinding → collection.

So, what role does the electrical system play in the splitting unit? Jiangsu Furi Precision introduced the fact that the electrical system is used to operate and control the individual equipment of the entire slitting unit, which is a non-standard design electrical control system. The control range is very wide, such as roll-up trolley and unloading trolley. The electric control system consists of PLC automatic control system, AC speed control system and digital display system. System design and component selection comply with IS9001 and CCC standards.

In addition, during the operation of the splitting unit, the staff can adjust by adjusting the speed parameter automatic balance adjustment and manual continuous adjustment function. At the same time, in the slitting unit, its electrical system is also equipped with an automatic board speed detection and automatic display system. The AC frequency conversion device equipped with the system is provided with input reactors to reduce pollution to the power grid side.
