Abstract

L'invention concerne un dispositif de préparation de colle et un procédé de préparation de colle. Le dispositif de préparation de colle comprend des dispositifs de stockage de solution (10), des corps de pompe (20) et un mécanisme de mélange de fluide (100). Il y a deux dispositifs de stockage de solution ou plus (10) pour le remplissage des solutions à mélanger. Au moins deux corps de pompe (20) sont agencés en correspondance avec les dispositifs de stockage de solution (10). Les corps de pompe (20) sont utilisés pour le pompage les solutions à mélanger dans les dispositifs de stockage de solution (10) dans le mécanisme de mélange de fluide (100). Le mécanisme de mélange de fluide (100) est utilisé pour le mélange les solutions à mélanger. Les solutions à mélanger dans les dispositifs de stockage de solution (10) sont pompées dans le mécanisme de mélange de fluide (100) au moyen des corps de pompe (20) pour le mélange, et la vitesse de pompage des corps de pompe (20) est commandé pour commander la quantité des solutions à mélanger pompées dans le mécanisme de mélange de fluide (100), ce qui permet la réalisation du mélange des deux solutions ou plus à mélanger selon un rapport prédéfini pour préparer de la colle.
