Today, our company will certainly present the application of high pressure fan in the supporter. First, our company are going to launch the mainstream printing press in the market:
1. Operating concept of display screen printing machine
Taking the generally used palm display screen printing machine as an instance, the functioning guideline of the screen printing press could be described as adheres to: The ride gear transmission electrical power, allows the activity of the scuffing plate extrusion ink as well as cotton monitor publishing, cotton display screen printing layer and the substratums to create a branding line, N1 as well as N2, because the screen possesses tension force F2 scraping board, for back to flex the cotton screen plate apart from the printed line is not touching substrates, inks in scuffing plate under the activity of the extrusion of F1, with the mesh, Leak coming from the relocating trace line onto the substratum.
In the printing process, the display screen publishing plate as well as scratching layer for relative motion, extrusion force F1 as well as flexible F2 likewise move synchronously, the display in the elastic activity, quick return and substrate out of contact, thus as not to blot unclean. That is actually, the display in the publishing trip, regularly in contortion as well as rebound.
After the completion of one-way printing, the ink scrape plate and also the monitor printing plate are separated coming from the substratum, and the ink yield process is executed all at once, that is, the finalization of a printing pattern.
2. Operating concept of flat display screen bent display screen printing press
Flat monitor area monitor printing describes the use of flat monitor publishing on cylindrical or even conelike area. Under certain disorders, it may additionally screen printing elliptic surface, drum surface area, arc surface area as well as other surface areas. Dry monitor surface area monitor printing machine is making use of standard monitor platter externally of the printing machine.
Working guideline of flat surface display screen printing press: A - curler bearing B - center bearing C - Variety bearing. When publishing, the flat monitor platter as well as substratum motion, as well as the scrape is actually stationary. The level display screen publishing plate braced on the screen frame is actually steered due to the flat display screen area monitor printing machine for even translation, due to the friction of the display screen platter is actually placed on the assisting unit of the substrate rotation. Free throw line rate of the surface area substratum at the embossing line is consistent with the relocating velocity of the plane display screen printing layer to achieve blemish publishing.
Theoretically, the embossing pipes ought to be at the highest bus of the surface area substrate to raise the off-screen Slant and also guarantee the high quality of publishing. So as to change quickly, the scratching panel usually utilizes 60 ° ± 15 ° leading Slant, which demands change of upright degree and upper and also lower sizes. Adjust to upright is actually to make certain that the reducing upper hand line does certainly not make sidewise variation when changing up and down, consistently lined up with the highest bus A; The scraper with a top Angle of 60 ° ± 15 ° is actually utilized to make certain that the scraper Angle α is formed after vertical installation. In the actual adjustment, to ensure that the degree monitor publishing layer as well as area substratum well-timed detachment, the trace series can be appropriate to the front end a little, particularly when the substratum size is actually big, the imprint series have to be swayed to the front end, area printing assistance unit is a range of kinds of special gadget, designed and also manufactured by the individual depending on to item criteria.
Cylindrical or cone-shaped compartment area publishing can easily utilize two pairs of curler bearings, the span and dimension of the proportion of less than 1.5 cover and also cup with the bushing assistance, smooth echoing containers could be pneumatically-driven device support. An elliptic area is actually around a component of a cylinder and also could be sustained by a cylindrical tessellation.
3. Process of printing machine:
( 1) the working cycle of level display printing press. Take flat display plate system monochrome semi-automatic hand screen printing machine as an example, among its own functioning pattern is actually: feed → installing → down platter → down to ink platter, back to ink platter → scratching stroke → up to ink platter → down to ink platter → lift platter → back ink stroke → clear away installing → obtain.
In the continual cyclic action, so long as the functionality could be understood, the amount of time filled through each activity should be actually as brief as feasible, so as to reduce each working cycle as well as strengthen work productivity.
( 2) Print line. In the printing travel, the ink and also display printing layer are kicked out to the ink layer, to ensure that the display screen publishing plate and the substrate form a connect with pipes, called the trace pipes. This line goes to the side of the ink scrape, and numerous embossing lines create the publishing surface. Attaining a perfect imprint line is hard because the printing stroke is a vibrant process.
1. Vacuum cleaner adsorption and dealing with feature: suction sucker is used for suction as well as dealing with. High-pressure follower is utilized as vacuum cleaner source, rotating feta, and high-pressure follower is used for non-destructive as well as continuous transmission of revolving feta.
2. Printing drying, high pressure fan geared up along with air knife, for rapid drying out reasons. The high pressure supporter is equipped with the air blade to help make the even function of proper and finishing.
3. High pressure fan blowing, utilized as the sky float of newspaper reducing machine, to ensure that newspaper cutting, newspaper without damage. Loose paper make use of, using high pressure fan as the sky nozzle, to ensure the paper separation, not due to electrostatic adhesion. In publishing field, using high pressure air blower suction and pressure distinct piling time is very long sheets of paper, in order to avoid later adherence, and also can immediately fast collection as well as gear box, using the high pressure suction supporter gear box, however likewise will be actually handled as just from the printer newspaper holding on the curler, to accumulate to slow down its own velocity.
