First, the adjustment of the parallelism between the three layers of the guide rail, the printing plate and the working platform. If the three layers are not parallel, the screen printer can hardly work. Generally, the guide rail or platform is used as a reference for adjustment.
      1 The platform and the guide rail should be parallel, and the squeegee plate is moved along the guide rail. If the two are not parallel, the squeegee will not always touch the platform with a certain pressure, and even the gap will occur. This adjustment has been adjusted before the machine leaves the factory.
      2 The screen printing plate and the platform should be parallel, otherwise the grid table spacing is inconsistent, causing the blade printing pressure and the screen printing plate deformation to be inconsistent. Therefore, the flatness of the frame itself should be guaranteed, and the Jianyu network printing is generally proposed by the user. Specific requirements.
Second, the ink scraper adjustment
      1 The adjustment of the parallelism of the platform by the squeegee can be adjusted separately for the left and right respectively. The left and right sides of the intermediate shaft can be adjusted with the top wire to adjust the left and right top wires.
      2 The adjustment of the inclination angle of the scraper is generally in the range of 65-85 degrees, and can be selected as needed.
      3 The adjustment of the printing pressure should be carried out in conjunction with the adjustment of the printing plate and the printing table. In screen printing, the adjustment of the printing pressure is actually an adjustment of the position of the squeegee.
      4 The length of the scraping board can not be adjusted, and it is supplied as a kit. Each set has several different lengths to choose from.
Third, the adjustment of the ink speed.
      Generally, the adjustment of the entire working cycle is realized by the adjustment handle of the continuously variable transmission device, and the speed of each link is ensured. All kinds of adjustments are equipped with corresponding locking mechanisms, and the blade printing operation must be carried out under locking conditions. Screen printing machine installation and maintenance, generally have specific provisions and requirements in the machine manual, the user can refer to the implementation. Stroke adjustment. Includes adjustments to the stroke size and travel position. The screen printing machine with the crank mechanism and the swing lever mechanism can realize the stroke adjustment by adjusting the radius of the crank and the swing rod, and the stroke is increased and the stroke is increased. The screen printing machine with pneumatic mechanism can realize the stroke adjustment by adjusting the position of the stroke switch. The stroke of the screen printer driven by the chain cannot be adjusted.
