Fully Automatic Roller-Press Pallet Production Line

· Product Overview

The fully automatic roller-type tray production line comprises a pulping system, a forming system, a drying system, a stacking system, a vacuum system, a high-pressure water system, and a compressed air system, and is used to manufacture egg trays, fruit trays, and other similar products. It utilizes waste paper such as used newspapers, used cardboard boxes, office paper, and trimmings as raw materials; after hydraulic pulping, screening, and water addition, the material is adjusted to a specified consistency to form a pulp slurry. This slurry is then fed into a specialized metal mold via the forming system, where vacuum adsorption shapes it into a wet blank. The blank is subsequently dried on the drying line and finally stacked to complete the production process.

RemarksThe above parameters are provided for reference only. As technology continues to evolve, the relevant data will be updated on an ongoing basis.

 

 

1. High output, high flexibility, and high return on investment
With a production capacity of 12,000 units per hour, it can simultaneously produce two types of slurry-based products, meeting multi-color requirements.
 
2. High degree of automation
Only 4–5 operators are required.
 
3. Energy Conservation
Multi-layer high-efficiency drying lines, combined with waste-heat preheating recovery and roll-forming transfer technology, effectively reduce energy consumption.
