Precautions for using an ink pad printer and daily maintenance tips

I believe that everyone is no stranger to silk screen printing. The silk screen has a thick ink layer. The printed pattern has a strong three-dimensional effect. It can touch the concave and convex feeling by hand. It is suitable for surface printing of high-grade products. The color expression is very good, and multi-color overprinting is troublesome. The surface requirements of the product are regular planes or curved surfaces, which have certain limitations in printing range.

In terms of substrate suitability, screen printing has great advantages, especially in the non-shaped plastic hardware electronics and direct consumer goods industries, screen printing has gained wide acclaim. However, there is no universal printing method in the world, and screen printing is no exception. In the field of industrial printing of small areas and irregular substrates, screen printing has encountered real troubles, which has led to the birth of pad printing technology. It can be said that although the pad printing technology and screen printing are very different, the industrial fields they are involved are extremely similar.

Today, I want to introduce you to the printing: the ink layer of the pad printing is thin, and it can print the color on any surface, showing very good color expression and printing adaptability. It is commonly called universal printing, except water and air can not be printed. Any object can be printed by pad printing.

Then, if you want to use it well, it is necessary to know the use of this equipment and daily maintenance. It is necessary to know that today’s Xiaobian is to bring you some notes and daily routines when using the pad printer. Maintenance experience, let's take a look at it.

The following points should be noted when using it daily:

1. The size of the steel plate should match the size of the oil pan, the tool holder and the oil roller. Pay attention to the choice of pad printing head: the hardness of pad printing glue can be divided into soft, medium and hard. The finer patterns are harder, and the printed parts are not suitable for soft rubber heads. In addition, the size and shape of the plastic head should be the same as the size of the pattern and the surface shape of the printed surface. Use of ink: Different materials must be used for printing different materials such as plastic, glass or metal. The ink should be stirred before it is injected into the oil pan. When the operation is paused, press the “empty line” button to let the scraping system continue to work to prevent the ink from drying out. During the printing process, an appropriate amount of thinner should be added according to the air drying speed to maintain the proper viscosity of the ink. Immediately after the diluent is added, the printing paste should be immediately mixed. If the printing paste is stained with dirt, it should be wiped off with a cleaning agent. The fixture is prefabricated according to the shape of the print. After printing, the steel plate should be cleaned with a cleaning agent and the oil roller should be removed for cleaning. Safe operation, it is not allowed to operate one machine at the same time to avoid accidents. Monochrome pad printing machine printing common problems, patterns appear bubble marks on the surface of the rubber head oil, sticky and deteriorated, broken. The center point of the glue head is just pressed against the dot pattern. The ink has deteriorated. The ink is not the correct diluent. Not sharp. The rubber head surface is insufficiently curved. The ink is too thin. The ink is less added with additives.

2. The pattern lines are rough and fuzzy. The surface of the rubber head is broken. The ink is too thin. The steel plate pattern is broken. Not sharp or notched. The design is rough. The steel plate pattern is too deep. The ink is too dry.

3, the pattern of ink color light ink is too thin. The ink precipitated. Add a large amount of filler (generally controlled at around 5%). The steel plate pattern is worn. The steel plate pattern is not deep enough.

4, the pattern appears excessive lines steel plate pattern wear. gap. The rubber head slider is loose. The pressure on the rubber head is too high.

5, the pattern appears deformed plastic head height is not enough. The shape of the plastic head is not properly selected. The pattern is out of print. The plastic head is too small and too hard. The pressure on the rubber head is too high.

Equipment maintenance and repair is especially important

Maintenance: Maintenance of the pad printer can extend its service life and ensure that the pad printer maintains good running condition and high printing accuracy.

Environment: The production environment should be clean and free from excessive dust. Keep the machine clean and use a plastic bag to protect it from dust during long-term downtime. Gas source: The gas used for the pad printing machine should be clean and dry, and the water in the water filter cup should be drained regularly.

Ink: During the printing process, ink often drip onto the pad printing machine. These inks may penetrate into the active part of the machine and solidify, which may cause difficulties in adjustment and even cause inaccurate positioning. Therefore, this phenomenon was found to be erased immediately during printing.

Machine parts: After printing, the steel plate, rubber head, blade, oil hopper, oil roller, etc. should be cleaned for later use. More advertising equipment prices are available in the advertising network.

Lubrication: The slide guides, bearings, rollers, and parts that move with each other need to be lubricated to make them move smoothly and reduce wear and prolong service life.

Well, the above is the content that I shared with you today, the precautions when using the ink pad printing machine and the daily maintenance tips. I hope that it will be helpful for everyone to use this device in the future.
