Definitions

  • the present invention relates to an automatic machinery, particularly adapted for manufacturing moulded articles from plant fibre slurry, and to process of manufacturing plant fibres moulded article.
  • Plastic is a synthetic polymers made of oil and natural gas. Plastic were introduced less than 100 years ago and quickly become the world's most use material, especially in packaging and containers manufacturing industries. The plastic materials commonly used for article moulding are polypropylene (PP), polystyrene (PS), and polyethylene (PE). However, there are many drawbacks associated with the use of plastic as raw materials for packaging or containers. Plastic is a major part of household waste and is non-biodegradable. It can take hundreds of years to break down in landfill. Plastics generate toxic emissions if incinerated and although some plastics can be recycled, the recycling process in many cases can be more expensive than the original material. Waste plastic litters found in rivers and seas where it is responsible for the deaths of thousands of seabirds, sea mammals and fish.
  • the pulp moulded products are biodegradable, recyclable, and more environmental friendly.
  • the pulp moulded products have several drawbacks. These products are preferably made from recycled pulp obtained from recycled newsprint or other recycled paper.
  • the paper recycling process involved pulping, screening, de-inking, bleaching and refining, which is costly and energy consuming.
  • various chemicals are used during the recycling process, which may cause environmental pollution if proper controls are not executed.
  • Fibre bearing material such as rice husk, straws, oil palm empty fruit bunch and frond are abundantly available in Asia country. These fibre bearing materials which are usually being abandoned may be used as raw material to replace paper pulp for making plant fibres moulded packaging and containers. Furthermore, the plant fibres slurry need not high cost of preparation before it is moulded into shape compared to paper pulp. Therefore it would be an advantage to transform the existing paper pulp moulding process to manufacture plant fibre moulded products.
  • Another object of the present invention is to provide a plant fibres moulded article forming machine having at least one thermal-press station located at each side of the forming station to increase the production efficiency.
  • a further object of the present mvention is to increase the speed of conveying operation by having an independent conveyor system attached to the corresponding thermal-press station in the plant fibres moulded article forming machine.
  • Yet another object of the present invention is to produce diluted plant fibres slurry comprising of water , 0.05% to 1.0% of fibres content, and 0.01% to 30% of food graded water resistant agent and oil resistant agent.

Abstract

La présente invention concerne un dispositif de moulage automatique et un procédé pour fabriquer un article moulé à partir d'une pâte de fibres végétales. Cette invention implique l'utilisation d'au moins une station de formage thermique qui est située de chaque côté d'une station de moulage. Chaque station de formage thermique est équipée d'un système de transport conçu pour transporter l'article moulé fini hors du dispositif de moulage automatique. Le temps nécessaire à l'opération de séchage thermique est sensiblement plus long que le temps nécessaire à l'opération de moulage et, pour cette raison, la présence de la station de formage de chaque côté de la station de moulage permet d'augmenter la vitesse de production.
