Abstract

Table de support de réseau de soupapes entraînée par une barre transversale magnétique exposée se rapportant au domaine de l'équipement industriel. La table comprend une table de support (1), un module d'entraînement de soupape (2) et un tuyau de collecte d'air (3). La table de support (1) est divisée en grilles d'aspiration d'air au moyen d'une structure composite composée d'une couche de matrice de blocs de soupapes (13) entraînée magnétiquement, d'une couche de grille (14) et d'une couche de tissu non tissé (15), et les grilles d'aspiration d'air sont en marche ou à l'arrêt de manière mutuellement indépendante. Lorsque la table de support (1) est utilisée comme une table de support pour un dispositif de coupe de plateau de table, le module d'entraînement de soupape (2) est disposé au-dessus de la table de support (1) et se déplace conjointement avec une tête de coupe (8), et une barre transversale d'entraînement magnétique du module d'entraînement de soupape (2) qui se déplace conjointement avec la tête de coupe (8) commande des soupapes d'air (13101) de blocs de soupape dans la table de support (1) pour leur mise en marche ou à l'arrêt pour mettre des blocs de soupape (131) en communication dynamique dans une région locale en forme de bande de la table de support (1) avec un ventilateur d'extraction (9). L'invention limite une section transversale d'aspiration d'air efficace de la table de support (1) pour qu'elle se situe à l'intérieur d'une région locale en forme de bande à proximité de la tête de coupe (8), ce qui permet d'obtenir, avec une puissance d'évacuation d'air réduite, un effet de maintien reposant sur une pression négative dans la région locale de la table de support. La table de support de réseau de soupapes entraînée par une barre transversale magnétique exposée présente les avantages suivants : une simplicité structurale, de faibles coûts de fabrication, un effet de maintien reposant sur une pression négative supérieur, un faible bruit et une faible consommation d'énergie pour la production et les opérations.
