Description

DESCRIZIONE DI INVENZIONE AVENTE PER TITOLO DESCRIPTION OF INVENTION HAVING BY TITLE

"stampi di formazione per fluff di cellulosa defibrata e/o macinata meccanicamente" "forming molds for defibrated and / or mechanically ground cellulose fluff"

Attualmente per fa formazione del fluff assorbente di cellulosa, avviene posizionando degli stampi (fig.A) solitamente in successione circolare per la distribuzione del prodotto eseguito e sagomato durante la rotazione). Attualmente gli stampi per tali operazioni, presenti sui mercato, hanno l'aspirazione (1) solamente nella parte inferiore dello stesso (fig.B),una rete o un lamierino microforato (fig.D) posizionato tra la parte inferiore (fig.B) e la parte superiore (fig.C). La parte superiore (fig.C) può essere di spessore variabile, da pochi millimetri fino a qualche decina di millimetri.il grosso problema che si crea, in particolare modo quando abbiamo la parte superiore (fig.C) di spessori elevatila si che il prodotto defibrato (2) non riesce a distribuirsi per tutta l'altezza nella parte perimetrica esterna.Questo poiché a mano a mano che lo stampo sp riempie di fi uff, lo stesso crea una diminuzione del potere aspirante.La nostra invenzione è di avere creato una situazione di aspirazione anche lungo il perimetro esterno (fig.G) ed avere così una uniforme distribuzione del prodotto lavorato (3), questo lo abbiamo ottenuto sostituendo lo spessore del materiale (fig.C) con un reticolo autoportant4 ed adeguatamente sagomato (fig.G) (in base ai profili da ottenere), che ci permette così di avere un'aspirazione anche laterale su tutto il perimetri della figura da ottenere (fig.E).La parte superiore (flg-F) è stata da noi sostituita con una lamina di acciaio inox di minimo spessore (1-2 mm), adeguatamente lavorata in base al prodotto da eseguire, che funge e sostituisce la parte superiore (degli attuali stampi) senza creare però spessori che possono inficiare nella buona aspirazione delio stampo stesso. Essendo lo stesso praticamente in aspirazione in tutte te sue parti (4), non si rilevano evidenti perdite di carico in aspirazione, potendo così installare ventilatori con potenze inferiori di circa il 30%. Otteniamo così anche un rilevante risparmio energetico oltre che ad un prodotto di qualità superiore. Currently, for the formation of the absorbent cellulose fluff, it takes place by positioning molds (fig.A) usually in circular succession for the distribution of the finished and shaped product during rotation). Currently, the molds for these operations, present on the market, have suction (1) only in the lower part of the same (fig.B), a mesh or a micro-perforated sheet (fig.D) positioned between the lower part (fig.B) ) and the upper part (fig. C). The upper part (fig. C) can be of variable thickness, from a few millimeters up to a few tens of millimeters. defibrated product (2) cannot be distributed over the entire height in the external perimetric part. This is because as the sp mold fills with fi uff, it creates a decrease in the suction power. Our invention is to have created a suction situation also along the external perimeter (fig.G) and thus have a uniform distribution of the processed product (3), this we have obtained by replacing the thickness of the material (fig. C) with a self-supporting4 and adequately shaped grid (fig. .G) (based on the profiles to be obtained), which thus allows us to have a lateral suction on the entire perimeters of the figure to be obtained (fig.E). The upper part (flg-F) has been replaced by us with a sheet of steel or stainless steel of minimum thickness (1-2 mm), suitably processed according to the product to be made, which acts and replaces the upper part (of the current molds) without creating thicknesses that can affect the good suction of the mold itself. As it is practically the same in suction in all its parts (4), there are no evident pressure drops in suction, thus being able to install fans with power lower than about 30%. In this way we also obtain significant energy savings as well as a superior quality product.

RIVENDICAZIONI Stampo caratterizzato da possibilità di aspirazione del prodotto anche sullo spessore perimetrico esterno, di qualsiasi figura geometrica e dì qualsiasi spessore. Tale stampo è caratterizzato da lamierini intersecati fra loro e lavorati cor adeguati profili (fig.F) orizzontali e/o verticali in base al prodotto finale o altro atto a creare la stessa situazione di necessità e utilità di aspirazione anche laterale Applicabiiità in qualsiasi tipologia di Industria, (farmaceutica-igienico sanitaria-alimentare-ecc.ecc.) alla quale serve una sagomatura di materiale defibrato;macìnato;granulato e/o comunque da formarsi a mezzo aspirazione. 1 Stampi in due o più settori sovrapposti con sagomatura/e centrale aspirante a mezzo canalizzazioni di aspirazione, atte ad avere in tutti i punti del volume della figura un'aspirazione ottimale. CLAIMS Mold characterized by the possibility of aspiration of the product even on the external perimeter thickness, of any geometric figure and of any thickness. This mold is characterized by sheets intersected with each other and processed with suitable horizontal and / or vertical profiles (fig.F) according to the final product or other suitable for creating the same situation of necessity and usefulness of aspiration, also lateral Applicability in any type of Industry, (pharmaceutical-hygienic-sanitary-food-etc.) which needs a shaping of defibrated material; milled; granulated and / or in any case to be formed by suction. 1 Molds in two or more superimposed sectors with central suction shape / s by means of suction ducts, suitable for having optimal suction in all points of the volume of the figure. 2 Stampi secondo rivendicazione 1 caratterizzati dal fatto che si possano avere sagomature diverse. 2 Molds according to claim 1 characterized in that it is possible to have different shapes. 3 Stampi secondo rivendicazione 1 caratterizzati dal fatto che si possano ottenere spessori diversi. 3 Molds according to claim 1 characterized by the fact that different thicknesses can be obtained. 4 Stampi secondo rivendicazione 1 caratterizzati dai fatto che vi è una griglia composta e sagomata 5 Stampi secondo rivendicazione 1-2-3-4- caratterizzati dal fatto che la composizione di tali griglie pre-lavorate ci rende il prodotto formato tridimensionale. 6 Procedimento di formatura e sagomatura del Fluff secondo le rivendicazioni da 1 a 5 caratterizzato dal fatto che ci permette di avere un prodotto perfettamente sagomato in tutte le sue parti e dimensionalmente preciso poiché il riempimento volumetrico della figura, avviene aspirando anche lateralmente in altezza sullo spessore, lungo i perimetri esterni.4 Molds according to claim 1 characterized in that there is a composed and shaped grid 5 Molds according to claim 1-2-3-4- characterized by the fact that the composition of these pre-machined grids makes the product three-dimensional. 6 Fluff shaping and shaping process according to claims 1 to 5 characterized by the fact that it allows us to have a product perfectly shaped in all its parts and dimensionally accurate since the volumetric filling of the figure takes place by aspirating also laterally in height on the thickness , along the external perimeters.
