How to debug the roll-to-roll screen printing machine?

Today, roll-to-roll screen printing machines are the most common in the industry and one of the newest printing devices in the modern printing industry. Maybe we don't know about the roll-to-roll screen printing machine. When we operate the roll-to-roll screen printing machine, we should debug it, so as to ensure the quality of the silk screen printing product. The accuracy of the printing plate directly affects the printing position accuracy of the printing material. So, how do you think the roll-to-roll screen printing machine is being debugged?

First, the squeegee adjustment

1. The adjustment of the brush 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.

2. The adjustment of the parallelism of the ink plate to the platform, the left and right respectively can be adjusted separately by adjusting the screw rod; the left and right sides of the middle shaft can adjust the left and right top wires, and the essence is to adjust the low position of the squeegee to the left and right respectively.

3, the adjustment of the board inclination is generally in the range of 65-85 degrees, can be selected according to needs.

4, the length of the board can not be adjusted, generally in accordance with the kit supply, each set has several different lengths to choose from.

Second, 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. Rails or platforms are generally used as a basis for adjustment.

1. The table 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 to be inconsistent. Therefore, the flatness of the frame itself should be guaranteed.

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.

Fourth, the itinerary 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.
