    Ink pad printing machine is one of the series of pad printing machines It adopts advanced and reasonable straight-line back and forth movement, with stable performance and simple operation The equipment adopts advanced and reasonable straight-line back and forth movement and vertical pad printing structure, with the advantages of stable performance, simple operation, printing text, pattern deformation, fast printing speed, beautiful and clear handwriting, and the adjustment of scraper and font steel plate is very convenient It is suitable for printing date of manufacture, shelf life, batch number, bar code and simple pattern on all kinds of bottles, cans, cups and boxes It can be printed on all kinds of materials and different surfaces The gravure pad can be divided into square plate and circular movable plate, and various printing symbols can be customized It is believed that we are not new to screen printing The ink layer of screen printing is thick, and the printed pattern has a strong three-dimensional sense You can touch the concave convex sense with your hands It is suitable for the surface printing of products The color expression is very good, and multi-color overprinting is troublesome The surface requirements of products are regular flat or curved surface, which has certain limitations in the printing range In the aspect of substrate suitability, screen printing has great advantages, especially in the non fixed plastic hardware electronics and direct consumer goods industry, screen printing has been widely praised However, there is no printing method in the world, screen printing is no exception In the field of industrial printing with small area and irregular substrate surface, screen printing has encountered real troubles, which gave birth to the transfer printing technology It can be said that, although there are great differences between pad printing and screen printing, they are very similar in the industrial field Today, what I want to introduce to you is pad printing: the ink layer of pad printing is thin, which can be printed on any surface, showing a very good color expression and printing adaptability Commonly known as printing, except that water and air cannot be printed, any object can be printed by pad printing So it is necessary to know the precautions and daily maintenance of the equipment if you want to use it well What I want to bring to you today is the accumulated experience about precautions and daily maintenance when using the pad printing machine Let's take a look at it The following points should be paid attention to in daily use: 1 The size of steel plate should match the size of oil pan, knife clamp and oil roller Pay attention to the selection of pad head: the hardness of pad can be divided into three types: soft, medium and hard The fine pattern is hard, and the soft rubber head is suitable for uneven printing In addition, the size and shape of the rubber head should be similar to the size of the pattern and the shape of the printed surface Use of ink: different printing materials, such as plastic, glass or metal, shall be used with different ink, and the ink shall be stirred before being injected into the oil pan When the operation is suspended, press the "blank line" key to let the oil scraper system continue to work to prevent the ink from drying In the process of pad printing, appropriate diluent shall be added from time to time according to the air drying speed of the ink to maintain the proper viscosity of the ink After the diluent is added, it shall be stirred immediately If the pad adhesive is stained with dirt, it shall be wiped off with cleaning agent The fixture shall be prefabricated according to the shape of the printed part After printing, clean the steel plate with cleaning agent and remove the oil roller for cleaning Safe operation, two people are not allowed to operate a machine at the same time to avoid accidents The common problems and patterns of monochrome pad printing machine are bubble marks, oil stains on the surface of the rubber head, which are sticky, deteriorated and damaged The center point of the rubber head is just pressed on the pattern of the point Ink deterioration The diluent used for ink is wrong Not sharp Insufficient curvature of rubber head surface The ink is too thin Ink less filling agent 2 The pattern lines are rough and fuzzy The rubber head surface is damaged The ink is too thin The steel plate pattern is damaged Not sharp or chipped The design is rough The steel plate pattern is too deep The ink is too dry 3 The pattern ink is light and the ink is too thin Ink deposition Excessive filling agent (generally controlled at about 5%) Steel plate pattern is worn Insufficient depth of steel plate pattern 4 The pattern shows excessive line steel plate pattern wear Gap The rubber head slider is loose Too much pressure on the rubber head 5 The height of the deformed rubber head in the pattern is not enough Improper selection of rubber head shape The pattern is out of print The rubber head is too small and hard Too much pressure on the rubber head The maintenance and repair of the equipment is particularly important: the maintenance of the pad printing machine can extend its service life, ensure that the pad printing machine maintains a good running state and high printing accuracy Environment: the production environment should be clean without too much dust Keep the machine clean and cover it with plastic bag to prevent dust during long-term shutdown Gas source: the gas supplied to the pad printing machine shall be clean and dry, and the accumulated water in the water separating cup of the water filter shall be discharged regularly Ink: in the printing process, there are often ink drops on the pad printing machine These inks may penetrate into the moving parts of the machine and solidify, resulting in difficulties in adjustment and even inaccurate positioning Therefore, this phenomenon should be eliminated immediately when printing Machine parts: after printing, steel plate, rubber head, blade, oil bucket, oil roller, etc shall be cleaned for later use More advertising equipment prices in the advertising network Lubrication: the sliding guide rail, bearing, roller and the parts with mutual activities of the pad printing machine need to be added with lubricant to make it move smoothly, reduce wear and prolong its service life Well, the above is what I'd like to share with you today I hope it will be helpful for you to use this equipment in the future.
