摘要:
The present invention concerns a screen printing method for creating an image on a target support (12). Said method comprising the steps of: providing a screen printing machine (1) comprising a supporting structure (4), which is movable between a lower position and an upper position, a matrix (7) mounted on said supporting structure (4), in which matrix, an image is defined, and a supporting surface (3b), said matrix (7) being faced to said supporting surface (3b) when said supporting structure (4) is arranged in said lower position; placing said supporting structure (4) in said lower position; applying ink on at least a portion of said matrix (7) to enable the ink to move from said matrix (7) to said supporting surface (3b), such as to reproduce said image on at least a portion of said supporting surface (3b); placing said supporting structure (4) in said upper position; providing a transferring support (10) to transfer the ink reproducing said image from said supporting surface (3b) to said target support (12), said transferring support (10) being provided with at least an adhesive portion; applying said at least one adhesive portion of said transferring support (10) to a region of said supporting surface (3b) on which the ink is placed; removing said transferring support (10) from said supporting surface (3b); and applying the adhesive portion of said transferring support (10), which carries the ink reproducing said image, to said target support (12), to allow the ink reproducing said image to move from said transferring support (10) to said target support (12).

"Máquina de estamparia rotativa com régua para tela autotensionável rolamentada e sistema de transmissão" trata da transformação da régua (1 ) de espalhamento da tinta de estampagem, em um eixo autotensionável com mancais (2 e 3) extremos, um mancal removível (2) e outro mancal estático (3) longitudinalmente, dos quais se projetam volantes (4) para recepção do anel (5) estrutural da tela (6) de estampagem, a qual é tensionada por meio de uma mola (7), sendo a posição relativa da referida tela (6) em relação ao anel (5) e ao volante (4) demarcada com ponto de referência (8), por fim a tela (6) é movimentada por um sistema de transmissão dedicado.
摘要:
La présente invention concerne un dispositif de mise en place et de retrait d'une racle (21) dans un cylindre d'impression en sérigraphie monté sur une machine d'impression. Il comprend un support (2) fixé sur le bâti (1) de la machine dans le prolongement dudit cylindre sur lequel une coulisse (3) est montée pivotante autour d'un axe parallèle ô l'axe dudit cylindre. La coulisse (3) est agencée pour permettre ô un coulisseau (9) de se déplacer uniquement parallèlement audit axe. Le coulisseau (9) est muni de moyens d'assemblage et désassemblage rapide (10,13) coopérant avec des moyens conjugués (14, 15) sur la racle (21) pour permettre de fixer ou retirer rapidement la racle (21) sur le coulisseau (9). Le coulisseau (9) est conçu pour permettre dans une première position limite située ô l'extérieur dudit cylindre de monter respectivement retirer la racle (21) et une seconde position limite ô l'intérieur dudit cylindre pour se placer face ô la position de travail de la racle (21). Dans cette position par basculement de la coulisse (3) la racle (21) est mise en position de travail respectivement retirée de la position de travail.
摘要:
The invention relates to a screen printing cylinder with a circular screen (103) and a doctor blade (101), arranged on the inner surface of the circular screen (103). A web (107), is arranged parallel to the cylinder axis on the lateral surface (105) of the doctor blade (101), facing the ink pushed before the doctor blade, whereby the doctor blade (101), a section of the circular screen (103) in contact with the above and the web (107), extending from the doctor blade (101), form an open channel bed opposed to the direction of rotation of the screen printing cylinder. Guide means, in particular, grooves (108) are arranged at at least both longitudinal end regions of the web (107), for diversion of the ink, scraped from the circular screen (103) by the doctor blade (101), along the longitudinal direction of the doctor blade (101) towards the middle thereof.
摘要:
A printer includes a print head (12) for dispensing viscous material (16), such as solder paste (16). The print head (12) defines a chamber and includes at least one source port (13) and a dispensing slot (24). Within the chamber, a flexible membrane (21) segregates the chamber into a dispensing region (18) and an activation region (19). Viscous material (16) flows from a supply mounted to the source port (13), into the dispensing region (18) and out the slot (24). A displacement mechanism is positioned to displace the flexible membrane (21) to reduce the volume of dispensing region (18) and to thereby dispense viscous material (16) through the slot (24). The print head (12) also includes a removable envelope (28) through which the viscous material (16) flows and contacts as it passes through the envelope (28).
摘要:
A Screen printing apparatus in which a squeegee head 13 is moved on a mask plate 12 thereby to print paste on a substrate through pattern hole 12a, slide contact portion 37A and 37B form respectively front and rear walls in the squeegeeing direction of a printing space 35 which reserves cream solder 5 therein and makes cream solder contact with the surface of the mask plate 12 through an opening portion formed at the lower surface thereof. Each slide-contact portion is configured by a partition plate 39 for partitioning between the printing space 35 and the outside and a filling block 38 having a filling surface 388a which forms an acute angle with respect to the surface mask plate 12. In squeegeeing operation, the filling surface 38a rolls the cream solder 5. Thus, the cream solder 5 can be filled into the pattern holes 12a without pressurising the cream solder, and a problem caused by the leakage of the cream solder can be eliminated.
