Layer panel forming machine

1、 Product Overview

The laminated panel forming machine, also known as the sandwich panel forming machine or composite panel production line, is a highly automated industrial equipment specifically designed for the continuous production of metal faced sandwich panels for construction. It produces building panels with excellent properties such as high strength, thermal insulation (based on actual reports), fire resistance (based on actual reports), and sound insulation by one-time composite molding of color coated steel plates (upper/lower panels) and insulation core materials (such as polyurethane, rock wool, glass wool, etc.) in the production line.

This equipment is an excellent core production equipment for modern industrial plants, logistics warehouses, cold storage, commercial buildings, clean workshops, and prefabricated buildings.

2、 Core working principle

The workflow of the layer panel forming machine is a continuous and integrated process, and its core principle can be summarized as "feeding → molding → gluing → compounding → curing → fixed length cutting → finished product".

Material release: The uncoiler carries steel coils and flattens them through a leveling machine to prepare for forming.

Forming: The flattened steel plate enters the forming machine and is gradually cold-formed through a series of detailed rollers to form the designed plate shape (such as corrugated, flat, etc.).

Glue coating: On the surface of the lower steel plate after forming, polyurethane foam adhesive or other adhesives are uniformly sprayed through an automatic glue coating system.

reunite with:

Upper panel: After being fed and formed, it is guided to the composite area.

Core material: The insulation core material (such as rock wool, glass wool board) is accurately fed between the upper and lower steel plates through a conveyor platform.

The three components (upper panel, core material, and lower panel) are preliminarily combined in the composite section.

Heating and curing: For polyurethane sandwich panels, the composite will enter a foaming oven with a specific temperature and length, allowing the polyurethane mixed with black and white materials to expand at a suitable speed in the cavity, filling the entire panel space and firmly bonding and curing with the metal panel. For rock wool and other boards, they are firmly bonded through a pressure section.

Fixed length cutting: The continuous slab that has been fully cured/composite is cut to the desired length by an automatic cutting device (such as a flying saw or grinding wheel saw) through a computer-controlled fixed length measurement system.

Finished product output: The single layer panel after cutting is automatically received, stacked or packaged by the discharge rack.

3、 Main equipment composition

A complete layer panel forming machine production line usually consists of the following systems:

Uncoiler system: including uncoiler and load-bearing steel coil.

Leveling system: Remove the curling stress on the steel plate and confirm that the surface is flat.

Forming system: The core part is composed of multiple detailed rolling rolls, which determine the final plate shape.

Glue coating system: used for mixing and spraying polyurethane foam.

Composite system: Integrate and pressurize panels and core materials.

Foaming system (PU/PIR board one-to-one): including material tank, high-pressure foaming machine, and drying channel.

Cutting system: automatic fixed length cutting to protect the smoothness of the incision.

Control system: PLC (programmable logic controller) and human-machine interface (HMI) touch screen, realizing the automation control and parameter adjustment of the entire line.

Discharge and palletizing system: automatically receives and stacks finished sheet materials.
