How to choose pad printing machine
Pad printing machines have been popularized for decades, and manufacturers are constantly upgrading in terms of structure and performance. Users will also provide advice based on their own operating experience. China is an important participant in the supply chain of the world pad printing machine market, providing global users with annual A wide variety of pad printers with different uses. For users who are new to pad printers, there are now more options for choosing pad printers than before, which means that you must understand the relationship between pad printer performance and price. If choosing a pad printer is important, I hope this article can help you understand this knowledge.
1. Choose an open pad printer or a closed pad printer?
The environmental tendencies of printing presses have been talked about for many years, and this is the number one issue for operators to provide health assurance. The quality control obtained by the use of solvent-based inks in pad printing machines has been difficult to replace by other water-based inks or UV inks for many years. For a long time, solvent-based inks will remain for a long time, and pad printing machines can do structural work. The first attempt is to adopt a closed oil cup structure, which has gradually entered the mainstream market in recent years, especially in developed countries in Europe and the United States.
2. Choose a touch screen or a microcomputer?
The structure of the original pad printing machine is relatively simple, and the action form is not complicated. It is relatively simple to use a microcomputer program to control, but the microcomputer program is a fixed program that is encapsulated, and the user cannot expand the function. When the structure of the pad printing machine is When it becomes complex and more functions are required, a PLC operating system with man-machine dialogue function may be more suitable. Manufacturers of pad printing machines have faced changes in the market in recent years. A more obvious trend is to manufacture pad printing machines with a high degree of automation, so the use of programmable and visual programs for mechanical control may be essential. For users, the pad printing machine with human-machine interface is better at realizing different printing tasks according to your own habits.
3. What kind of plates are used?
Pad printing machines generally use thick steel plates, thin steel plates and resin plates. For domestic users, the use of resin plates is not a good option. Therefore, steel plates are generally used. The plate-making method of steel plates involves a process that is not very environmentally friendly, but as far as the current environmental protection policy is concerned, it is acceptable. Many European customers prefer to use resin plates, which are made with only water and alcohol, and are preferred despite their low print durability.
4 Cleaning the plastic head unit
The cleaning head unit is a separate part, you may need it for an additional fee, and you may opt out of it. We know that cleaning the glue head is done manually at first, and it is important to keep a part of the residue on the surface of the glue head in the process of transferring ink. Accumulation for a period of time will cause quality problems. The usual method is to remove it with adhesive tape. Causes downtime, but the pad printer installed with the automatic cleaning glue head device will perform the online cleaning step, and the time required to clean the glue head is far less than the time to manually clean the glue head after the shutdown. On higher-end pad printers and automated pad printers, it has become very common to install an automatic cleaning head device.
There are so many types of products printed by pad printing machines and screen printing machines that it is difficult for you to use a standard mechanical structure to achieve all printing tasks. You can only design different transfer devices according to different products. In this regard, the role of the manipulator is very powerful. The manipulator can grasp different products and feed materials to serve the main body of the printing press.
The manipulator imitates the action of the hand, which does not seem to be continuous, but it is very easy to carry large spaces and long distances. It is widely used in rotary pad printing machines or products with complex product shapes. Of course, not all products are suitable for using robots. You must discuss with your partners what structure to use to maximize efficiency.
There are many types of workbenches for pad printing machines, such as shuttle workbenches, turntable workbenches, and disc workbenches. Each workbench now has a variety of structures to choose from. For example, shuttle-type worktables are controlled by pneumatics and servo motors. Many users have instructed that the positioning accuracy of servo-motor-controlled worktables is relatively high. In order to improve the accuracy of rotary table-type worktables, linear guide rails have also been used in recent years. , the trend of servo motor drive. You will also find many users in the market using disc-type workbenches. The disc-type workbench is an intermediate form of the transition from semi-automatic pad printing machines to fully-automatic pad printing machines. With the cooperation, the market share is steadily increasing.
