Fully automatic screen printing machine technology is now more and more mature, and more and more products are available for purchase in the market. At present, the automatic screen printing machines on the market can be divided into two types: single sheet automatic screen printing machine and roll material automatic screen printing machine. Some users will choose semi-automatic screen printing machine and hand printing table. This time I will talk about roll-to-roll screen printing. Insider of the three major industries of the machine.
　　1. The structure is unreasonable. The salient feature of the roll-to-roll automatic screen printing machine is the roll-to-roll printing. Regardless of its applicability, it does not start from actual industry applications, such as front-end feeding system and induction box. It has a very simple structure. Some manufacturers have used it for several years. Without updating, the two-column structure of the machine girder and guide column is easy to loose and cause the color registration to be inaccurate for more than ten years.
　　2. The temperature of the oven is uneven. The roll-to-roll automatic screen printing machine generally adopts a back-type oven because of its floor space design. The design of unilateral heating and unilateral heating will cause the problem of different temperatures between the left and right materials, especially when the temperature is too high. , The temperature difference is even greater. At 180 degrees, the temperature difference between the left and right sides of the material can reach about 40 degrees, which is easy to cause uneven shrinkage and inaccurate color registration. If the material is deformed during proofing, the general manufacturer The problem of inaccurate color registration will suggest the customer to change the material for testing
　　3. Accuracy of color registration. There are several aspects to the color registration accuracy control of the roll-to-roll automatic screen printing machine. One is the balance adjustment of the pulling drum and the stability of the pulling servo and reducer. The second is the compactness of the structure when the web arm is installed, and the machine head is installed. Compactness, the third is the balance of the vacuum platform, the fit of the beam guide column, etc., these are the keys to the accuracy of color registration.
　　4. Energy-saving aspects of the machine. The energy-saving aspect of the roll-to-roll automatic screen printing machine mainly lies in the design of the oven. For the oven of the same power, the temperature loss and the control of the uniformity or heating method are all issues that the machine manufacturer must consider.
