On the main principles and advantages of self-made

Talking about the main principles and advantages of self-made curved surface printing machine

first, the advantages of self-made curved surface printing machine

curved surface printing machine itself is not a high-tech product, which is neither complex nor abstruse. Anyone who knows a little about the principle of mechanical braking and has rich printing experience can get materials locally and make their own. The self-made curved surface printer has no electrical device, which avoids the maintenance trouble caused by circuit and air circuit failure in use; Moreover, the self-made curved surface printer has the advantages of light weight, low cost, simplicity, flexibility and multi-function. It not only changes the cumbersome, expensive, single function, rigid and monotonous of the traditional curved surface printing machine, but also caters to the particularity and diversification of modern curved surface substrate

second, what is curved surface printing

as the name suggests, in order to achieve the purposes of beautification, decoration and embellishment, the surface structure or shape is not a plane, but a curved, arc, concave and convex shape. "Dr. Robert Ernst Siebert, the managing director of bentler Sigri, introduced the formed objects of various materials, such as water cups, wine cups, teapots, ashtrays, various bottles and tubes commonly used in our daily life, as well as chemical Plate printing at specific or unspecified positions on the surface of test tubes, smoking cups, measuring tools, etc. for medical experiments can be called curved surface printing

III. The importance of scraper selection

the selection of scraper is very critical in curved surface printing (Note: sometimes ignored by many plate printers). Scraper (also known as doctor blade), specifically, it is a hand or machine tool that squeezes the ink on the forming plate onto the substrate. It is usually composed of polyurethane strips with a thickness of 8 ~ 10mm and a hardness of 60 ~ 80 shore (Shore A) and wood or aluminum handles. Experienced plate printers know that the doctor blade used in curved surface printing must have the conditions of two high and four resistance, that is, high elasticity and high hardness; Chemical resistance, solvent resistance, acid and alkali resistance, abrasion resistance. Especially when printing exquisite curved objects in chromatic printing, the choice of scraper should be paid more attention to. Only in this way can we achieve twice the result with half the effort, which has been proved to be the same in practice

IV. main principle of curved surface printer

we explain it with cylindrical objects. Most of the cylindrical curved surface substrates use bearing type outer diameter four point support to complete the rolling printing. There are no cases of self-made curved surface printers. Some customers even remove their hearts and chat with us, but there are two sets of devices more than other curved surface printing machines. It is different from that when printing unconventional or large taper objects, and when there are utensils with handles, special micro auxiliary runner and probe rod inner diameter telescopic runner are added

① the special micro auxiliary runner is for printing objects with a diameter of 0.8 ~ 2cm (such as craft chopsticks, ball point pen shell, brush holder, glass test tube, etc.)

the vibration phenomenon occurs after the start of the experimental machine ② the probe rod type inner diameter telescopic runner is specially designed for the use of the improved FST (objects that cannot be printed normally supported by the flame point) and the substrate with the handle (such as ceramic teacups, enamel teapots, stainless steel fast food cups, etc.) with a large taper and relying solely on the outer mirror four econcore. When rotating, the device is light and stable, and can also be freely adjusted according to the inner diameter of the substrate. It belongs to the six point support of the inner cavity, and the telescopic adjustable rotary rolling completes the printing. During the operation of scraping during formal printing, the regular positioning of the workpiece is the same as that of overprint and conventional curved surface printing machines
