Abstract
Zariadenie je určené na lisovanie nekonečného pása na báze rotačného lisu. Rotačný topný válec je upravený tak, že na plášti topného valca je drážka v tvare rybiny s uhlom pri záikladni a híbke požadovaného nekonečného pása. Zariadenie je možné využit pri výrobě dokonaléhoi súosého spoja a rovnakého rozměru nekonečného pásu.The device is designed for pressing an endless strip on the basis of a rotary press. The rotary heating cylinder is arranged so that on the shell of the heating cylinder there is a groove in the shape of a dovetail with an angle at the base and depth of the desired endless strip. The device can be used to produce a perfectly coaxial joint and the same dimension of the endless strip.
Description
Vynález sa týká zariadenia na lisovanie nekonečného pása na báze rotačného lisu. Lisovanie nekonečného pása sa doteraz prevádzalo na rotačných lisoch s vyhrievaným valcom s hladkým plášťom.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a rotary press-based endless belt pressing apparatus. The continuous belt pressing has hitherto been operated on rotary presses with a heated roller with a smooth shell.
Pri doteraz známej technologii lisovania nekonečného pása ná súčasnom zariadení dochádza na okrajoch vylisovaného pása ku strate hrúbiky oproiti volenej hrúbke. Táto časť sa preto ořezává v šírke 25 až 30 mm ako odpad. Ďalšou nevýhodou súčasného strojného zariadenia je unášanie drátenky, pomocou ktorej sa lisuje nekonečný pás, v dósledku čoho dochádza pri nekonečnom páse s pozdlžnym dezénom k výraznej šablovitosti. Tento nedostatok sa rieši ořezáváním dvoch okrajov tak, aby sa doclelilo nepřerušené pokračovanie vzoru po celej kladenej dížke pásu. V súčasnosti bolo vyvinuté zariadenie na lisovanie nekonečného pása na báze rotačného lisu s vyhrievaným valcom ipodla vynálezu.In the prior art technology of pressing a continuous web, the thickness of the oproit of the chosen thickness is lost at the edges of the molded strip. This section is therefore cut at a width of 25 to 30 mm as waste. A further disadvantage of the current machinery is the entrainment of the wire, by means of which the endless belt is pressed, as a result of which, at the endless belt with the longitudinal tread, there is a distinctive saber. This drawback is solved by trimming the two edges so that the pattern continues throughout the entire length of the strip. A rotary press-based endless belt press has now been developed with a heated roll according to the invention.
Podstata vynálezu spočívá v tom, že na zariadení na lisovanie nekonečného pása na báze rotačného lisu s vyhrievaným valcom je na plášti topného valca zapuštěná dráž- ka v tvare rybiny, s uhlom 40° až 85° pri základni a híbke požadovaného nekonečného pása na zabezpečenie dokonalého súosého spoja a rovnakého rozměru nekonečného pásu.The essence of the present invention is that a dovetail groove with an angle of 40 ° to 85 ° at the base and the depth of the desired endless belt is provided on the heating roller housing on a rotary press with a heated roller, at an angle of 40 ° to 85 ° to ensure perfect concentric joint and the same dimension of the endless belt.
Na výkrese je upravený rotačný topný válec. Po celom obvode plášťa rotačného valca 1 je vyhotovená drážka v tvare rybiny 2, rovnoramenný lichoběžník s váčšou základňou bližšie k osi rotačného valca v híbke 3, v akej sa bude nekonečný pás vyrábať. To znamená, že drážka je v spodnej časti širšia 4 ako okraj, kde drážka začína 5. Tento rozdiel vytvára na plášti rotačného valca skosenie 6. Sikosenie je možné vytvoriť pod uhlom 7 od 45° až po 85°, najvýhodnejší je uhol 75°. Výhody vyvinutého zariadenia umožňujú pri rovnakých výrobných nákladoch zúžitkovať vyrobený nekonečný pás v celej šírke, bez vzniku odpadu, čím dojde k úspoře na materiálových nákladoch, energiách a pracovných silách.A rotary heating cylinder is provided in the drawing. A dovetail 2 groove, an isosceles trapezoid with a larger base closer to the axis of the rotating cylinder in the shaft 3, in which the endless belt will be produced, is formed over the entire circumference of the rotating cylinder housing 1. This means that the groove is wider in the lower part 4 than the edge where the groove starts 5. This difference creates a chamfer on the jacket of the rotating cylinder 6. The slope can be formed at an angle of 7 from 45 ° to 85 °, most preferably an angle of 75 °. The advantages of the developed equipment allow, at the same cost of production, to utilize the endless belt produced in full width, without waste, thus saving on material costs, energy and labor.
Zariadenie vylučuje problém vznikaijúci unášaním drátenky, zabezpečuje po celej dížke rovnaký rozměr nekonečného pása. a spoj bez šablovitosti, čím odstraňuje obojstranné orezávanie nekonečného pása.The device eliminates the problem of entrainment of the wire, providing the same dimension of the endless belt over the entire length. and seamless joints, eliminating double-sided trimming of the endless belt.
