Under the great wave of China's intellectual creation, HC Machinery Industry Network will hold the “Smart 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 omnidirectional 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. Shenzhen Shuangling Special Silk Printing Machinery Co., Ltd. will also participate in this forum to seek new development directions for enterprises. Founded in 1996, Shenzhen Shuangling Special Silk Printing Machinery Co., Ltd. is a professional printing equipment manufacturer integrating design, production, sales and service. Its own brand SUNLIT has grown into a modernized scale after years of operation. enterprise. This article will introduce you to the manual round screen printing machine.
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 severe 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, thereby avoiding blocking. When selecting the ink, the weather 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 the ink on the surface of the screen printing machine, and replace the ink with high viscosity, when appropriate. 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.
The thickness of the flat screen printing mechanism plate can be ensured by selecting a high-mesh screen and a high-resolution photosensitive material to reduce the occurrence of defects.
There are always various fault problems in the printing process of the screen printing machine, such as manual and semi-automatic all do not operate, the power light is on, and the printing seat does not move after moving left. A fault phenomenon: when the semi-automatic time does not step on the foot switch and immediately act; the second fault phenomenon: when the semi-automatic work is performed, the pedal switch slides down, and then rises after being released. This phenomenon is generally caused by damage or disconnection of the proximity switch on the left side of the cross slide. The solution is to replace the proximity switch or connect the switch.

Children Furniture Sets Desk Chairs
igrow study table and chair, the height of the table and chair can be adjusted according to the height of the child. In addition to the most basic "cushion height" that can be adjusted, the "armrest and back cushions" can also be adjusted according to the child's thigh length and waist height. Adjust so that the child does not sit in the wrong position due to the improper height of the table and chair. And the chair is designed according to children's ergonomics, unlike ordinary chairs that are straight up and down, there is a double-back curve design, which supports the child's back and ensures that the waist and hips fit perfectly with the chair.
