Pad printing machine has the role of high efficiency, environmental protection and energy saving. It can be divided into vertical pad printing machine, inclined arm pad printing machine, rotary pad printing machine, four-column pad printing machine and automatic pad printing machine. Mainly used in the electronic processing industry, printed circuit board screen logo, instrument shell panel logo, circuit board processing process solder paste printing. So what problems need to pay attention to before the pad printing machine starts?1, the pad printing machine must be cleaned when in use, after cleaning treatment to make the pad printing machine better use, to avoid the problem of dust caused by corrosion of the machine, the service life can also be extended. The inside of the pad printing machine must be in a normal state, and there must be no foreign body, otherwise it will certainly lead to the problem of obstruction, and only by ensuring that it is in a normal state can it be better used.

1. Quality requirements of silk screen printing machine original manuscriptThe original manuscript is the basis of printing and reproduction, and the quality of the original manuscript directly affects the printing and reproduction. When receiving the business order, accepting the original manuscript and carrying out the process design, the original manuscript submitted by the customer should be carefully reviewed to determine whether it meets the requirements. Different printing methods have different requirements for the original manuscript, such as whether the original manuscript meets the characteristics of the printing method; Whether it is suitable for the reproducible range of process operations in plate making and printing. That is, the selection of patterns, text and colors in the original manuscript must first meet the production requirements of plate making and printing, and then be suitable for the actual level of equipment, materials and operations of the printing manufacturer; Some even have to consider whether they can meet the specific practical standards of printed matter. Only in this way can we ensure that the printed matter reaches a more ideal quality standard.

Pad printing machine should pay attention to daily maintenance, in order to extend its service life and bring great benefits to the enterprise. At the same time, it can ensure the consistent quality of printing and save input costs. Not only to do a good test, but also to do maintenance. Nip in the bud, and you'll be better at work.The use of pad printing machine must be checked regularly, first of all to ensure that the power supply is non-destructive and no leakage phenomenon to avoid safety hazards. Secondly, it is necessary to check the wear and tear of various parts such as oil and water separators, gas pipes and so on, and whether they work normally to avoid the failure of parts during work. The working air pressure should also be checked and maintained regularly, so as to ensure the stability of the printed pattern, ensure that the quality meets the requirements, and reduce the rework rate.

The working principle of screen printing machine.The full name of the Screen printing Machine is "screen Printer" (Screen Printer Machine), which is a device that leaks the screen printing ink to the printed surface according to the shape of the screen opening. It can be divided into vertical screen printing machine, inclined arm screen printing machine, rotary screen printing machine, four-column screen printing machine and automatic screen printing machine. Mainly used in the electronic processing industry, printed circuit board screen logo, instrument shell panel logo, circuit board processing process solder paste printing. Screen printing is the silk fabric, synthetic fiber fabric or metal wire mesh stretched on the screen frame, using hand-carved paint film or photochemical plate making method to produce screen printing plates. Modern screen printing technology is to use sensitive materials to make screen plates by photographic plate making (so that the screen holes on the graphic part of the screen plate are through holes, rather than the screen holes on the graphic part are blocked). When printing, the extrusion of the scraper makes the ink transfer to the substrate through the mesh of the graphic part, forming the same graphic as the original manuscript. Screen printing equipment is simple, easy to operate, simple printing, plate making and low cost, strong adaptability. Screen printing has a wide range of common prints: color oil paintings, posters, business cards, bound covers, commodity signs and printing and dyeing textiles.

Pad printing machine is mainly used for the production of screen printing products, in plastics, ceramics, toys have more applications. Pad printing machine also has a variety of types, so today's small series is mainly to analyze the precision of pad printing machine is not enough.1. Pad printing machine pad printing steel plate: when several color plates are placed in the wrong position, pad printing color accuracy decreases, or the pattern on the plate is not good, resulting in insufficient fineness.2. Glue head: the glue head is not installed in the central position; The size of the rubber head is different or the hardness of the rubber head is inconsistent; The pressure of the glue head on the steel plate or substrate is not uniform.3. Substrate: the substrate should have a certain degree of softness and hardness and the smoothness of its surface.4. Other aspects: positioning, fixture and workpiece fixing must be reliable.Pad printing machine is a professional printing equipment, there are many points of attention for the operation of pad printing machine, here, small series of pad printing machine operators fixed correct operation to explain.

Pad printing machine principleThe principle of pad printing machine is to first use the method of photographic plate making to print the required pattern, make the steel plate into a gravure plate and then transfer it to the printed material through a special silicone printing head, and according to the material of the product, the special ink can be modulated to ensure the quality. First, the design pattern is etched on the printing plate, the etching plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head.1. The ink is evenly covered on the steel plate by the brush;2, the excess ink will be scraped by the scraper steel knife;3. From the printing head down to the steel plate, the ink in the pattern is picked up;4, from the printing head shift down to the product will cover the pattern.How to use pad printing machine, manual pad printing machine use method

First, screen printing machine screen frameGenerally there are two kinds of wooden frame and aluminum frame: the price of wooden frame is cheaper, the packaging is safe, suitable for manual printing, but the recycling is relatively poor, because the net pulled out of the wooden frame is easy to relax, reduce the recycling of the net, the price is a few dollars, aluminum frame relative to the wooden frame has its effect of reaching a high recovery rate, not described here!Second, silk screen gauzeThere are many kinds, like nylon gauze, tapecord gauze, metal gauze and other wine packaging, from the cost and applicability of consideration, generally use nylon gauze, in addition, there can be a difference in color, for dyed gauze, this is relative to the combination of four colors printing, because dyed gauze can be Mohr phenomenon, this is later to say, here do not say, This remember said before the mesh mesh number, I said "T" is only the mesh model electronic supervision code, mesh number of the expression method should be mesh/square meter, generally 77T=180 mesh 100T=250 mesh 120T=300 mesh 140T=400 mesh 165TT, I do not remember, do not know whether, please correct the combination printing, In addition, there are 43 tons of mesh. 34T. There are other models!

How to use pad printing machine to print good productsSome customers buy back a pad printing machine do not know how to use, how to better print their own products. Now let's talk about how to use pad printing machine.First, the use of pad printing machine, we must first know what the pad printing machine consumables are,Pad printing machine consumables are: steel plate, plastic head, fixture, ink, these consumables to cooperate with each other in order to print good products.1, want to print a good product etching steel plate is very important, first of all, we have to see what the pattern printed by the customer is like, is a number or English letter or a small pattern this is very simple ordinary etching can, if there are some large patterns must be sandblasted on the steel plate so that the etched steel plate transfer to the substrate effect is very good.2. Rubber head: The selection of rubber head in different products is completely different, according to different products and the size of the pattern to be printed to select the size of the rubber head and the hardness of the rubber head.

The maintenance and maintenance of pad printing machine involves various aspects of management: here only points out the basic requirements that must be met to maintain the normal operation of the machine, and other aspects of management need to be regulated by the user to formulate relevant rules and regulations.First, air compressor: moisture with moisture in the air duct is easy to reduce the service life of air compressor components. Although the machine entrance is equipped with a three-point combination filter, if the place where the air compressor is placed is wet, a large amount of water vapor will be operated by the air compressor. When entering the air compressor, in this case it is necessary to install a freeze dryer to completely remove water in the air or often discharge the water in the filter cup and the water vapor in the air compressor cylinder.Two, three point combination: the air pressure should be maintained at 4~6bar. Although the filter cup has an automatic drainage function, if the filter cup holds too much water, you can manually remove the water vapor in the cup.
