Under the big wave of China's intellectual creation, HC Machinery Industry Network will hold the “Intelligent Future – 2016 Machinery Industry Summit Forum†on February 16, 2017. This year's ceremony will invite experts in the industry to the machinery industry. Carry out comprehensive and multi-angle analysis, and strive to find new development points in the machinery industry in the era of the Internet, and provide useful information for the future planning of enterprises. This article will introduce you to the fully automatic screen printing machine production line.
Screen printing machines are prone to failure when printing, some are unilateral reasons, but more are complicated reasons, so the operator of the flat screen printing machine should pay special attention to the cause of the failure, so as to take corresponding countermeasures.
1. Blocking, that is, the part of the image with mesh can not transfer ink during printing. This phenomenon will affect the printing quality. In serious cases, normal printing will not be possible.
The solution adopted is as follows: change the printing material that is not easy to drop powder, reduce the viscosity of the ink, so as to avoid blocking. In the selection of ink, the climate influence should be considered, the viscosity of the ink should be appropriately reduced, and the fluidity of the ink should be improved.
2. The ink does not adhere to the substrate of the flat screen printing machine
Solution: Regularly clean the flat screen printing machine to remove oil and dust, corona and plasma on the surface of non-polar products, improve the adhesion of ink on the surface of the screen printing machine, and replace the ink with high viscosity. You can add new ink.
3. Ink film edge defects, when printed with a flat screen printing machine, the edge of the saw is broken, the general quality of the screen printing plate, the edge should be smooth.
By selecting a high-mesh screen and a high-resolution photosensitive material, the thickness of the flat screen printing plate can be ensured to be uniform, and the occurrence of defects can be reduced.
Automatic material saving device, printing object spacing 1-0.5 (mm) to save materials. At the same time, the protection screen will not be broken due to the knife. Usually, the parts of the automatic screen printing machine should be checked regularly for looseness, whether the screws are tightened, etc. If you find a fault, do not open it yourself, in case the line is wrong. It may damage the whole machine. It is best to ask a professional to guide the repair. Finally, if the automatic screen printing machine takes a while to start using, then clean the machine and put it in a cool, dry place to prevent moisture.
