Pad printing machine working principle
1.fixed most of the oil pan and the oil cup pad printer , especially large Pad printing machines, generally use a fixed oil pan and oil cup , this kind of Pad printing machine is relatively simple mechanical construction is very sturdy . Printing head assembly driven out by a glide , slide the print head assembly generated by impact, will inevitably produce printing head shaking , thus limiting the body's printing speeds.
2.Activities Activities oil pan and oil cup oil pan and the oil cup of the print head moves only up and down , there is no mechanical shock , vibration also reduces print head , so , most of the high-speed Pad printing machine oil pan and use activities oil cup .
Printing process
Pad printing machine can be divided into open and closed oil basin oil cup system , plastic head stroke movements in the two systems operate on the same.
1.Open the oil pan
(1) When the printing head moves forward , oil repellent stick to pattern etching printing plates filled with ink.
(2) When the printing head moves backward , the plate scraper scrape off the excess ink , leaving only the part of the ink pattern etching .
2. Sealed oil cup system
(1) When the oil cup push forward , the ink is supplied to the cup position the printing plate etching , ink filled therein.
(2) When the oil cup returns, ceramic cup oil scraper ring will be like the principle of transfer printing and gravure similar tools include silicone printing plastic head , drying patterned print version ( steel or fiber ) and the ink can be printed system for all kinds of hairlines , fonts and patterns , and even four -color halftone images. Whether printed surface is convex or concave is irregular , still able to print out the desired effect, for example, on the golf course is the trademark printing four -color Pad printing machine which an expertise. Generally completely blow away the excess ink .
The five main elements of printing
1.Seal Oil Cup : Set Sealed storage scrape excess ink and ink functions in one.
2.Printing rubber head : This is the ink from the printing plate to the surface of the product media .
3.Printing plates : Etching printed pattern .
4.Ink : According to the printing requirements to determine color.
5.Pad printing machine : Run transfer printing .
Sealed oil -sealed cup blend inks and scraping clean the ink storage functions in one . Ink on the printed board surface and seal oil cup ceramic ring between the blades . Ink is sealed in the oil cup , the ink is exposed to air to minimize the opportunity to reduce the amount of ink evaporation , to keep the ink density stability , thereby ensuring stability of the desired print results.
Select the printing head and the printing ink tips
To get clear , sharp print results, select the printing head should pay attention to :
1.Try to choose round or conical printing head .
2.Try to choose a printing head angle is large .
3.If the product is able to withstand the pressure , you should use a hard head , because the hard plastic head live longer , and can print out a clearer pattern. Is filled with a variety of printing ink market , screen printing is also used in printing inks , printing inks fine must have the following characteristics:
(1) strong adhesion to the printing surface .
(2) Good liquidity , some ink into a paste , not in an oil cup or oil basin flow.
(3) When Thinner evaporate as inks , can play its stickiness.
(4) slight luster pigment will make more apparent , reducing the transparency and general printing ink of the normal thickness of 7μm.
(5) Ink printed surface gloss can not be affected by the change .
(6) can be drying but does not affect its viscosity .
If the ink is too strong, printing plates will be difficult to clean , resulting in static problems ( from hair ) ; If the ink is too thin , it will increase the transparency , it is difficult to transfer ink printing head .
Because there is a lot of different inks, hard of specified Thinner or add water slowly dry time and frequency , we can only be determined by observing the printing effect . Pad printer
A printing equipment for plastics, toys, glass, metal, ceramics, electronics, IC seal. Pad printing is an indirect printing technology may be concave plastic head, has become a variety of surfaces and decorative printing a primary method. Pad printing machine operation
Etching the plate ( steel ) coated with ink method : etching plate inking in a lot of ways .
First, the ink is sprayed on the etched board with a retractable blade and the excess ink is scraped off . At this time , stay in the erosion area of volatilization of the solvent in the ink and the surface of the gel is formed , and then etching down to the first plastic panel , suction ink.
Suck ink and printed products: plastic head suction plate etching ink big department increased after this time, this layer of ink and a volatile sector , leaving a sector not dried ink surface is more conducive to the object to be printed with the rubber head close combined . Plastic head shape to be able to produce a rolling action to drain the surface of the ink etched plates with excess air .
In the production process of the ink and the plastic head The ideal situation is that all the ink etching the board are all transferred to the object to be printed , in the production process ( approximately 10 microns or 0.01 mm thick, adhesion of the ink is transferred to the matrix ) plastic head printing easily affected by air temperature, static size effect . If the transfer from the etching plate plastic, the entire process to the substrate , the evaporation rate and the dissolution rate control in an equilibrium state is good , it is considered a successful printing . If evaporate too quickly , even before the ink is absorbed dry . If evaporation is too slow, has not yet formed gel ink surface , easy to make plastic head and matrix attachment. Pad printing machine technical features

This is to improve production efficiency, reduce costs necessary way , but also printing technology from labor-intensive industries to technology -intensive industries into the necessary requirements.
Currently, the high degree of automation is relatively common printing machine rotary printing machine delivered its printing process is fully automated . Affected by the degree of automation , the vast majority of companies consider the quality of the printing process in the countermeasures issues are still imperfections, even if such a printing machine, in order to complete a truly automated printing but also faces many challenges.
Universal automatic pad printing machine is relatively rare, but specific products targeted automatic pad printing machines still have a lot of surprises. For example , printing the CD automatic printing machine, automatic printing bottle cap printing machines. Pad printing machine automation essentially means that the product conveyor automation , as part of the change is small pad printing . A variety of information on new technologies broadened our horizons, other printing technologies penetrate , let us generate new inspiration, customer requirements will inspire passion printer manufacturer . Pad printing machine technology since its inception, especially after entering the domestic market , with regard to its obvious advantages are more and more business concerns . It is combined with screen printing technology , co-development of the printing market situation. From the traditional labor-intensive to technology-intensive gradually forward. This is a trend to adapt to world development . Currently , printing machine printing processes are constantly improved and perfected .
Ink for printing technology is essential . Today, the emergence of closed ink can be said printing machine printing technology , a new progress . First, it is energy-saving , environmental protection, because it saves the amount of ink , while health workers also enjoy a more comfortable environment . Second, it saves time and effort , because the long-term stability of the viscosity of the ink , it eliminates the cleaning cartridge after printing , squeegee trouble. In addition, during mass production operation, the use of closed ink is easy to do . It combines the use of staff into consideration the more factor that makes the production efficiency and quality of the further improved.
Currently printing process is also to update the field forward. In order to more effectively put into production , printing technology is gradually completed online production, the printing machine and the entire production and operation of organically combined to form a complete and unified link. Currently printing printing technology is gradually moving towards automation , high-precision systems not only through the quality of printing that accuracy , it is adapted to the needs of mass production . In addition, the pad printing technology is gradually and production environment , consumption and maintenance products form a complete part. Now with the pad printing machine printing trade descriptions , trademarks and other patterns more and more manufacturers , and exactly why they are willing to choose printing machines as their choice of whether the printing machine 's competitiveness in the wrong ?
In fact ,pad printing machine printing equipment does have many of the same advantages you do not . First, a printing machine can do up to 12 chromatic called multicolor overprint , one will be able to print all the products , thus improving efficiency and saving money , even just a small construction firm can afford these costs , compared to similar products multicolor screen printing machine overprint becomes expensive it. Secondly, it compared the characteristics of screen printing machine ,pad printing machine ink layer is very thin, which means it is easy to leave marks on the surface of any product , whether it is flat, curved or wavy surface , can be a perfect copy printed pattern However screen printing machine in this respect is very complicated, flat screen printing machine can print screen , if you want to print the application surface and will face another wave surface screen printing machine up . Moreover , printing machines with very good color performance and printability , although the pattern printed silk screen technology three-dimensional sense of strong, rugged touch can feel the real sense , but if the types of products than printed ,pad printing machine can definitely be called a panacea, either plastic or metal , whether it is sports or glass, it is a piece of cake for the pad printing machine . Such formal printing machine performance, low price point was completely special completely adapted to this highly developed commercial material society , became the first choice of contemporary manufacturers , such as Ningbo and Shanghai printing machine printing machine is moved printer's producing provinces for the entire society with high efficiency machinery. Seal oil cup pad printer
Open type ink tank with respect to an alternative model is to seal the ink tank. Served in a flip ink container,
Through the pressure plate in contact with the etching. The container scraper remove ink from the etching plate. Since the container is sealed, so that the solvent does not evaporate, the ink remained stable conditions, to make the machine cycle longer.
Although these models seem to solve the problem of stability of the ink, but how to properly deploy the ink is still very important issue, many factors will affect the volatile solvent. Press * for must be quite serious and responsible,Otherwise it will wear etched plates and the container will put ink sprayed outside the etched plate. And for an ink tank is expensive. Such systems are increasingly used in automated production lines. Pad printing technology theory
define the use of soft Pad printing plate transfers the ink on the image area to the substrate in the printing machinery. Indirect printing machine printing is an important one .
Power Source:
Pad printing machine main action can be divided into: plastic head dipped under the pressure of the ink on the pad plate and elevation ; rubber head moves to the upper substrate ; printing plastic head under the pressure elevation after printing . Three kinds of action leading to the different ways to control printing machine determines the three basic categories :
Manual pad printing machine, three kinds of actions are controlled manually . Is the simplest printing machines, only complete small batch production orders and product sampling tasks.
Electric pad printing machine, three kinds of actions are motor driven and controlled. Printing speed, but the printing pressure is small, only a smaller area to complete the production date of printing and bar code products. |
