Balloons made of latex can be floated in the air after being filled with air to obtain a wide range of visual expression. Now it has become an important toy for children. As the main carrier of advertising and wedding industry to promote and express the atmosphere of joy. Balloons also have a wide range of practical expressions. For example, wedding cars, wedding rooms, open arches, and decorative temporary stages. In order to achieve significant publicity, printing on balloons is a very common practice. After being filled with air, the balloon is soft, and presents a roughly spherical or ellipsoidal body. It will undergo certain deformation after being subjected to pressure. These features provide natural guarantees for the application of screen printing, and the screen printing pressure is small. The version can adapt to the deformation of the balloon, and it is easy to find a flexible ink suitable for the latex material. The pneumatic device of the screen printing machine is easy to install an inflatable device to inflate the balloon and ensure the stability of the size. The screen printing machines currently printing balloons on the market are mainly semi-automatic screen printing machines and automatic screen printing machines. Semi-automatic screen printing machine prints one color at a time, needs to complete the inflation by hand, and then placed on the work table to complete the printing, because the amount of inflation is not easy to control, the position of the hand placed balloons is also difficult to be unified, the unity of the printing is difficult to get Guarantee. It's even harder to color. Semi-automatic balloon screen printing machine is mainly used for small-volume, single-color, low-quality balloon printing. Fully automatic balloon screen printing machine optimizes the blowing device and carries out quantitative automatic control. It ensures that the size of the balloon after blowing is roughly uniform. The transfer after blowing is also relatively stable. After entering the printing position, the initial position is basically maintained and the position of the printing pattern is relatively neat. It is easier to achieve color registration, and the speed is greatly improved. The main requirements for the printing on the balloon are the printing color and the printing position. The first is the printing position. The balloon cannot be printed at any position. Given that the balloon needs to be printed after being inflated, it is impossible to print near the gas nozzle. The symmetry of the gas nozzle is usually difficult to print, and the position where the printing can be performed is basically disaggregated. The sides of the balloon. Placing one side in the circumferential direction on both sides of the ball, printing on both sides of the symmetry and four positions at an angle of 90 degrees can basically meet the requirements of all balloon users. Therefore, the balloon screen printing machine basically targets these four positions. By installing an automatic rotation device on the machine, printing can be conveniently performed at these four positions. Then printed color. Monochrome is naturally simple. If color registration is required, the machine will have to be more complex. Some factories adopt the design of a rotating disk, and some factories adopt a streamlined design. The balloons in turn enter different printing stations to perform the task of color registration. The SA2 series automatic balloon screen printing machine adopts a rotating disk mechanism, which has a higher overprint accuracy.
