Laeg LD350 series packaging machine solutions

I. Overview

     Traditional printing presses generally take a variety of ways, speed, web offset printing machine, for example, web offset printing press using DC speed control to multiple sets of gears vice speed variable unit In order to achieve speed operation, monochrome lithographic printing press web and two-color offset printing machine for web drive system, with the rapid development of information technology, intelligent packaging printing presses began to show their prominence in the packaging industry. Through sophisticated sensing equipment and control systems, the use of sensors, image recognition, machine vision and artificial intelligence and other advanced technologies, to achieve a better level of automation and intelligent functions, so as to ensure the stability and consistency of packaging quality.


     Printing machine inverter is an essential electronic equipment in the modern printing production process. Its role is not only to reduce production costs and improve production efficiency, but also to ensure production safety, reduce noise and vibration, and improve the working environment and the health of employees.


2.the working principle of Lange frequency converter application

The control core of the packaging machine is the tracking system, which adopts forward and reverse bi-directional tracking to further improve the tracking accuracy. After the machine is running, the film marking sensor constantly detects the film marking (color marking), and at the same time, the tracking microswitch of the mechanical part detects the position of the machinery, and the two signals mentioned above are sent to PLC, and after program calculation, the output Y1 (positive tracking) and Y2 (reverse tracking) of PLC will control the tracking motor to track in both positive and negative directions, so that the error of the packaging material in the process of production will be detected in time and accurately compensated and corrected, avoiding the waste of the packaging material. It can accurately compensate and correct errors in the production process of packaging materials, avoiding the waste of packaging materials. If the inspection fails to meet the technical requirements after a predetermined number of tracking times, the machine can be automatically shut down and wait for inspection to avoid the generation of waste products.


3.Composition of the electrical system of the automatic packaging machine

     The transmission system used although the application function is relatively simple, but the dynamic performance of the transmission has high requirements, the system requires faster dynamic following performance and high stable speed accuracy. Therefore, we must consider the dynamic technical indicators of the frequency converter, the choice of high-performance frequency converter in order to well meet the process requirements.

    The electrical part of the automatic packaging machine is generally composed of the following:

  (1) the main control circuit consists of inverter, programmable logic controller (PLC) control core.

  (2) temperature control circuit consists of intelligent temperature control table, solid state relay, thermocouple components, temperature control is accurate, intuitive display, easy to set.

  (3) Multi-point tracking and detection is realized by photoelectric switch, electromagnetic proximity sensor and so on.



4.Features of Laeg's LD350 inverter

Lange LD350 frequency inverter can meet the requirements of packaging machine because it has the following characteristics:

(1) Applying the rotational frequency automatic compensation control technology to automatically correct the frequency to achieve the effect of stabilizing the motor speed when the load changes.

(2) It has high speed stabilization accuracy and fast dynamic response, which can meet the transmission control requirements of high-performance occasions. Reduce the time and economic loss caused by transmission system failure. It has lower maintenance cost.

(3) It has the advantages of rich functions, stable performance, miniaturization and low-noise operation.


Examples of field applications:

5.Advantages of applying Lange LD350 frequency conversion speed control

(1) Simplify the transmission system, greatly reduce the failure rate, and reduce the maintenance cost of the enterprise.

(2) Increase production and reduce cost. It can improve the production technology, so that the product output and quality are improved, and can effectively save costs and realize greater profits.

(3) Realize softwareization of control and improve performance.

(4) Realize non-tripping operation through functions such as torque compensation, stall prevention and restarting; make the produced products of stable quality and improve efficiency.


The company adheres to the engineering design principle of "first-class service, Excellence, pragmatism and pursuit of Excellence".
