What Is the ACP Sheet Stripping Machine?
To understand the aluminum-plastic composite panel peeling machine, one must first grasp what an aluminum-plastic composite panel looks like, and then examine how this machine “takes it apart.”
Structure of Aluminum Composite Panels
You have undoubtedly encountered aluminum-plastic composite panels on the street: on bank facades, subway signage, gas station canopies—many of those sleek, eye-catching panels are, in fact, this very material. But what does it look like on the inside?
Aluminum-plastic composite panels consist of a total of three layers.
| Layer | Material | Characteristics |
|---|---|---|
| Top Layer | Thin Aluminum Sheet (approx. 0.2–0.5 mm) | Waterproof, corrosion-resistant, features a metallic finish |
| Middle Layer | Plastic Core (primarily Low-Density Polyethylene) | Lightweight, resilient, provides cushioning |
| Bottom Layer | Thin Aluminum Sheet (similar in thickness to the top layer) | Also aluminum; serves protective and decorative functions |
How are these three layers stuck together?
A special bonding film (a high-molecular adhesive membrane) is situated between the aluminum skin and the plastic core material. Through a process of high-temperature thermal pressing, this layer firmly “welds” the aluminum and plastic together.
If you wish to separate the two, an aluminum-plastic panel stripping machine is absolutely essential.
How an ACP Sheet Stripping Machine Works
Traditionally, the process of recovering aluminum from aluminum-plastic composite panels (ACPs) relied almost entirely on manual labor: workers would first pry open the edges of the panels and then painstakingly peel off the aluminum sheeting piece by piece. However, this method is quite labor-intensive.
In reality, since ACPs are originally manufactured through high-temperature thermal pressing, the reverse principle applies: by heating the panels to a specific temperature, the aluminum and plastic components can be easily separated.
Modern ACP Sheet Stripping Machine is designed based on this very concept. The complete system primarily comprises a peeling mechanism, a discharge mechanism, rollers, and sprockets, as well as a power system consisting of a motor and a speed reducer. During operation, the motor drives the speed reducer via a belt; the reducer, in turn, drives the entire machine to rotate steadily and smoothly, ensuring highly reliable performance.
