Application of Decoiler Straightener Machine in the Home Appliance Industry

Traditionally, decoiling and straightening are performed by separate machines, which results in average space utilization and relatively complex setup and operation. As the home appliance industry continues to demand higher production efficiency and product quality, the 2-in-1 decoiler straightener machine has emerged. Next, we will explore the application of the decoiler straightener in the home appliance industry.

Decoiler Straightener Parts Introduction

1. Decoiler Mandrel

Decoiler mandrels are available in two designs: powered or non-powered. Expansion methods include manual or hydraulic expansion. Non-powered decoiler mandrel requires ensuring sufficient traction from downstream equipment (straighteners, feeders).

2. Straightening Section

(This is an RGL-200. The straightening section can be adjusted freely.)

The feeding angle of the straightener entrance can be adjusted to prevent coil bending, which could damage the coil surface.

3. Straightening Rollers

(This is an RUS-200F. The upper straightening rollers are lifted.)

The upper straightening rollers can be designed to be liftable for easy cleaning, which is friendly to soft materials such as aluminum.

Home Appliance Industry Production Characteristics

1. Coil Properties

The coils' width is mostly medium to thin(0.3–4.5 mm), mainly cold-rolled steel and aluminum.

2. High surface quality

High surface quality is required, avoiding scratches, creases, and roller marks.

3. Large Production Volumes

The home appliance industry typically uses high-volume continuous production lines, which require stable and efficient equipment to ensure capacity.

Advantages of the Decoiler Straightener

1. Compact Footprint

Saves space and is suitable for workshops with limited space.

2. Liftable Straightening Rollers

Allows easy cleaning of rollers to prevent leftover debris from scratching the material surface.

3. Short Distance Between Uncoiler and Leveler

Easier adjustment and reduced material changeover time, ensuring production efficiency.

Why Choose a Decoiler Straightener

For common home appliance production, the integrated machine provides efficient and stable feeding and leveling, making it a cost-effective choice. Compared with separate decoilers and straighteners, it does not require calibration for each machine, reducing material loading time. Its compact design allows manual feeding of the coil into the leveler entry. Compared with NC straightener feeder machines, the decoiler straightener has a lower initial investment, smaller footprint, and simpler maintenance. Although its leveling capability is not as good as NC straightener feeder machine, it can meet the general production needs of the home appliance industry.

(Here is a comparison of the separate decoiler and straightener, 2-in-1 decoiler straightener, and NC straightener.)

In Which Product Lines is it Applied

Generally, the maximum material width that a decoiler straightener can handle is 1000mm, and the maximum material thickness is 6.0mm. If the maximum material width is 1300mm, the maximum material thickness can only be 3.2mm. For materials like aluminum, the maximum material width is 600mm, and the maximum material thickness is 1.5mm.

1. Small finished parts (<500mm)

Rice cooker, small coffee machine casing, small oven panel.

2. Medium finished parts (500~700mm)

Microwave oven panel, dishwasher casing.

3. Large finished parts (700~1000mm)

Air conditioner outdoor unit casing, refrigerator door panel, TV back panel.
