Heavy-duty decoilers are versatile and widely applicable in various industries, offering numerous customization options and classifications. Despite the diversity in design, these powerful machines share a common working principle, with each type having unique features and control systems. In this article, we’ll delve into the intricacies of heavy-duty decoilers, their electronic control boxes, and how to utilize their control panels effectively.

Understanding Heavy-Duty Decoilers and Their Working Principles

Heavy-duty decoilers operate by using a motor and reduction gearbox to drive spindle rotation for decoiling processes. They also incorporate an induction rod (frame) and electronic control box to enable automated start-stop functionality. The control systems for these machines are generally located in an electronic control box mounted on the side of the device.

Exploring the Two Types of Electronic Control Boxes

There are two distinct types of electronic control boxes for heavy-duty decoilers, each with its own set of features:

  1. Standard Black Small Box: This compact control box contains components such as AC contactors, time relays, and intermediate relays. Lacking speed adjustment capabilities, its panel is equipped with fuses, power indicator lights, automatic operation, forward and reverse rotation, and six switch button components for automatic, off, and manual modes.
  2. Advanced White Box with Frequency Converter: This larger control box features an integrated frequency converter, allowing for speed adjustment. It also includes additional switch button components for fine-tuning panel speed and a tachometer.

A Comprehensive Guide to Control Panel Switch Buttons and Functions

To help customers maximize the efficiency of their heavy-duty decoilers, we offer an in-depth look at the control panel’s various switch buttons, their respective states, functions, and operation, using the electronic control box as a reference.

Component Name Status Operation Instructions
Fuse Connected/Broken When the decoiler is overloaded or has a malfunction, the fuse will blow to protect the electrical components in the electrical box. Replace the fuse after troubleshooting.
Power Indicator On/Off This light is on when the power switch is set to “On.”
Power Switch Off/On Decoiler operation switch (Note: This switch is for operation, and there is still power in the control box when it is turned off. Disconnect power before opening the box.)
Auto Auto When the switch is set to Auto, the heavy decoiler will operate automatically based on the sensor.
Stop Off When the switch is set to Off, the decoiler is stopped and cannot operate.
Manual Manual When the switch is set to Manual, the decoiler can be controlled by pressing the “Forward” or “Reverse” buttons.
Forward None/Press Start When the decoiler is in Manual mode, press this button to uncoil forward.
Reverse None/Press Start When the decoiler is in Manual mode, press this button to uncoil in reverse.
Speed Adjustment Knob Adjustment Uncoiling speed adjustment knob; turn right to increase speed and left to decrease. (Note: Increase speed for prolonged use to extend motor life.)

Note: The forward and reverse operation of the heavy-duty decoiler must be performed in manual mode. If the switch is set to automatic (or off), the “forward” and “reverse” switches will become inactive.

Modifying Induction Delay Time in the Electrical Control Box

Inside the heavy-duty decoiler’s electrical box, a time relay is present. To alter the induction delay time, users can access the electrical control box and make adjustments as needed.

By understanding the different types of electronic control boxes and their corresponding functions, users can optimize the performance of their heavy-duty decoilers for a wide range of applications.
