Description

przedmiotem wzoru uzytkowego jest zgrzewadlo folii stanowiace zasadniczy roboczy zespól w maszynie pakujacej.Znane sa i powszechnie stosowane rozwiazania zgrzewadel folii z wykorzystaniem termicznego procesu ciecia, w których elementem grzejnym jest drut oporowy KANTALA, zas do zgrzewania stosowane sa tasmy oporowe KANTALA. Docisk elementu tnacego w znanych rozwiazaniach nastepuje od dzialania sprezyny osadzonej na sworzniu poprzez boczne plytki dociskowe* Mankamentem znanych rozwiazan jest nierówny rozklad temperatur i nacisków, a w konsekwencji zukosowania i zrywanie folii.Istota rozwiazania, wedlug wzoru uzytkowego jest konstrukcja zgrzewadla folii, którego element roboczy stanowiacy tnaco-zgrzewajaca listwe osadzony jest bezposrednio miedzy zewnetrznymi zgrzewajacymi listwami polaczonymi ze soba srubowymi elementami.W zewnetrznych zgrzewajacych listwach, od wewnetrznej strony uksztaltowane sa gniazda pod grzejne elementy.- 2 - W rozwiazaniu wedlug wzoru uzytkowego wykorzystanie zgrzewajacej listwy zapewnia uzyskiwanie bardzo waskiego liniowego zgrzania polaczonego z liniowym cieciem folii. Polaczenie liniowego zgrzania z powierzchniowym zgrzaniem od zewnetrznych zgrzewaja¬ cych listew gwarantuje odpowiednia wytrzymalosc i wysoka jakosc zgrzania przy jednoczesnym krótkitol czasie zgrzewania• Zgrzewadlo wedlug wzoru charakteryzuje sie prosta, lekka zwarta konstrukcja, latwym montazem i demontazem z pakowarki, jest zespolem zgrzewajacym bardzo wydajnym z mozliwoscia szczególnie korzystnego wykorzystywania w automatach o duzej wydajnosci w liniach technologicznych pakowarek, niezaleznie od ich typu i przeznaczenia.Przedmiot wzoru uzytkowego uwidoczniono na rysunku, na którym fig. 1 przedstawia schematycznie widok boczny zgrzewadla folii, fig. 2 - schematycznie przekrój poprzeczny plaszczyzna A-A przez zgrzewadlo folii z alternatywnym mocowaniem zaciskowo lub srubowo zewnetrznych mocujacych listew.Zgrzewadlo folii wedlug wzoru uzytkowego zbudowane jest z zewnetrznych zgrzewajacych listew7 1_ polaczonych ze soba srubowymi elementami 2_. Miedzy zewnetrznymi zgrzewajacymi listwami 1_ znajduje sie tnaco-zgrzewajaca listwa 3..- 3 - W zewnetrznych zgrzewajacych listwach l^od wewnetrznej strony uksztaltowane sa gniazda 4. pod grzejne elementy 5,. Zewnetrzne zgrzewajace listwy 1_ zawieszone sa na dwustronnych srubach ^6, wzglednie zaciskowo uchwytami 7, • Powierzchnie robocze zewnetrznych zgrzewajacych listew J_ i tnaco-zgrzewa- jacej listwy 3_ pokryte sa antyprzylepna warstwa 8 folii 3.RZEC^K PATENTOWY Nr 346/ Itngf iriz. Jan Proscinshi10 72 40 Cu $q&8 PLThe subject of the utility model is a foil welding machine, which is the basic working unit in a packaging machine. There are known and commonly used solutions for foil welding using a thermal cutting process, in which the heating element is KANTALA resistance wire, and KANTAL resistance tapes are used for welding. The pressure of the cutting element in known solutions takes place from the action of the spring mounted on the pin through the side pressure plates * A drawback of the known solutions is the uneven distribution of temperatures and pressures, and consequently the chamfering and breaking of the foil. The essence of the solution, according to the utility pattern, is the construction of the foil welding gun, the working element of which is The cutting and welding strip is mounted directly between the outer welding strips connected with each other by screw elements. On the outer welding strips, the sockets for the heating elements are formed on the inside from the inside. - 2 - In the solution according to the utility pattern, the use of a very narrow welding strip ensures a very narrow welding strip with linear foil cutting. The combination of linear welding with surface welding from external sealing strips guarantees adequate strength and high quality of welding with a short welding time at the same time. • The pattern sealer is characterized by a simple, light, compact structure, easy assembly and disassembly from the packaging machine, it is a very efficient and very efficient sealing unit. particularly advantageous use in machines with high efficiency in technological lines of packaging machines, regardless of their type and purpose. The subject of the utility model is shown in the drawing, in which Fig. 1 shows schematically a side view of a foil welding gun, Fig. 2 - a schematic cross-section of a plane AA through a welding gun foil with an alternative clamping or screw fastening of the external fastening strips. The foil heating element, according to the utility model, is made of external welding strips 7 1_ connected with each other by screw elements 2_. Between the outer sealing strips 1_ there is a cutting-welding strip 3 ..- 3 - In the outer sealing strips l ^ on the inside there are 4 slots for heating elements 5. External welding strips 1_ are hung on double-sided screws ^ 6, or clamped with handles 7, • Working surfaces of external welding strips J_ and cutting-welding strip 3_ are covered with anti-adhesive layer 8 of the foil 3.
