[China Packaging Network] The type of screen printing machine is very many, but in our daily life, the most widely used is the six-color screen printing machine this model, and this model is the most What is unpleasant is its installation and maintenance. Then how should it be installed and maintained?
In fact, the installation and maintenance methods of the six-color screen printer mainly include the following aspects:
First, the phase adjustment of the whole machine work cycle: It is strictly adjusted by the manufacturer according to the designed cycle phase diagram, and is pinned or locked.
Second, the operation adjustment: Rails, plates and work platforms to adjust the degree of parallelism between the three layers: generally guide rail or platform as a benchmark for adjustment.
1. The platform and the guide rail should be parallel. The squeegee moves along the guide rail. If the two are not parallel, the squeegee will not always contact the platform with a certain pressure, even a gap occurs. This adjustment is also adjusted before the machine leaves the factory. Now.
2, the screen printing plate and the platform should be parallel, otherwise the network distance (the distance between the bottom of the screen printing plate and the printing surface) is inconsistent, which causes the printing pressure and the screen printing plate to be inconsistent. Therefore, the flatness of the frame itself should be guaranteed. , Generally, the user makes specific requirements as needed.
Adjustment of the edition: refers to the adjustment of the printing accuracy between the screen printing plate and the printed article on the screen printing machine. Height adjustment (>40mm), front and rear adjustment and left and right adjustment (>20mm), horizontal angle adjustment (>3°).
Third, squeegee adjustment:
1, the squeegee to adjust the parallelism of the platform, adjust the left and right screw to adjust the height of the squeegee; the left and right top of the middle shaft can be adjusted with the left and right top wire, in essence, to the left and right of the ink plate to adjust the height position.
2. The adjustment amount of the scraper inclination angle is generally in the range of 65° to 85°, which can be selected according to the need.
3. The adjustment of printing pressure is actually the adjustment of the position of the squeegee.
4, the length of the squeegee can not be adjusted, generally provided by the kit, each set has several different lengths available for selection.
Fourth, stroke adjustment: including the stroke size and stroke position adjustment. Through the adjustment of the radius and R hole of the crank and the swing rod, the stroke adjustment can be realized. R can increase the stroke, and the stroke length generally exceeds the pattern by 20-50mm.
Fifth, the network (table) distance adjustment: by reducing the screen printing plate or raising the platform can achieve network (Taiwan) distance adjustment, generally using the method of raising the platform. Screen printing plate angle from the square to be consistent, the error ≤ 0.5mm. The distance from the net station is generally 2 to 5 mm. Only when the netting compensation operation is performed, the net station is allowed to go from the front to the back.
Sixth, the speed of the squeegee adjustment: to fast all the actions are faster, slower each action is slow.
The above is a detailed description of the installation and maintenance methods of the six-color screen printing machine. If you want to know more about the screen printing machine, please continue to pay attention to the Chinese packaging network!
