DBL system of Continuous PU Sandwich Panel Production Line-The Most Important Component

What is the role of Double Belt Conveyor？

DBL is mainly used to overcome the expansibility of foaming and make it solid, and decide panel thickness and production speed. Side belt is overcome horizontal expansion and decide width of panel and guiding to the panels. As active running moulds, it avoids panel deformation and scratch and to ensure panels quality.

Components

It consists of upper and lower steel belts, transmission system, side belts and hydraulic lifting system.

Pu sandwich panel continuous production line

Main Structure

The DBL consists of two heavy duty independent conveyor structures (lower and upper) supported by columns which are placed on the floor. The lower conveyor is fixed to the columns by means of welded metal structures and with coupling bolts and screws. The surface of DBL is covered a group of polished steel panels of 200mm chain plates, these panels is connected with wearable bears so that to form a chain driven system with high strength. For these panels, we adopt anti-corrodant welding structure and tooled on high accurate lathe so that to ensure that user can change the panels in future. And for workpiece we adopt double surface seaming and double side in time to keep the level sliding surface smooth, high precise and hard to deform.

Lower belt is installed a corrugated panel moulds that is anti high temperature and anti corrosion, and also installed magnetic steel and pins on the moulds for easy installation and disassembling.

There's side belt on each side of DBL, speed is same with the double belts. Level distance can be adjusted to suit different width. It’s driven by motors and adjustment device is high precision and operation easy, high automatization.

Different panel thickness and profiles nylon moulds is different.

Feature

1. Drive adopts frequency vector technology, speed adjusted automatically to keep same speed with upper and lower belt.

2. Reasonable adjustment device, with electric control hydraulic jack, frequency motor adjusting width and thickness of sandwich panel, which is easy and safe.

3. Upper and lower belt is consisted with chain plates, special structure design to make the panel surface flat, thickness even, not easy to deform and scratch.

4. Each chain plate adopts anti-erosion welding structure which can guarantee the changeable of the plates.

5. Lower belt is installed a corrugated panel moulds that is anti high temperature and anti corrosion, and also installed magnetic steel and pins on the moulds for easy installation and disassembling.

6. Guiding rail surface treated with quenching, high hardness and grinding performance well, long duration.
