The printing of paper brick products mainly has two types of patterns, spot color overprinting and four-color dots. Both types of printing are compared with the positioning requirements. At present, domestic factories use the sea of ​​people tactics, and the manual screen printing station is equipped with a set of clamping fixtures. Each person is responsible for one color. If the product is four-color, it will be a group of four people. This traditional way when the labor cost was not high in previous years, the factory felt that there was nothing to be improved. Anyway, everyone is doing this. Find a way to increase the working speed of workers, and the cost can be reduced, but this process has the following limitations:
1. Dependence on familiar craftsmen is relatively high, (if a newly-started employee, the printed pattern will be inconsistent in depth, and the printed in different time periods are different)
2. Low production efficiency
3. Incorrect registration
4. High-precision printing is difficult to control quality
With the current post-90s personnel entering the labor market, the above four points have become more and more difficult to control because of the difficulty in recruiting workers in the past two years. When the current workers choose occupations, they will be very difficult Pay attention to the environment and labor intensity of work, manual screen printing has relatively high requirements for hand strength, and it is extremely tiring to work after a day. After doing a period of time, this part of the staff will choose another job, resulting in a high turnover rate and quality of the internal staff of the factory. And output are difficult to control. Most heads of paper brick factories have a headache for this situation, but there is no good way to solve this situation.
A small paper brick screen printing machine has been developed for paper brick printing, which solves the above problems comprehensively. This machine has the following characteristics:
1. The pneumatic screen printing structure is automatic, as long as the air pressure is stable in the range of 4-7bar, the printing quality is always stable, free from the dependence on skilled craftsmen
2. Install a set of paper clamps that are automatically clamped and loosened. The paper bricks are clamped during printing, and they are automatically released after printing. The workers just take the paper bricks and work, which greatly reduces the labor intensity of the workers. , Making screen printing work simple and easy
3. The printing speed is fast, the speed of the whole machine can be adjusted according to the operator's proficiency in picking and placing bricks, the fastest speed can be up to 800 times / hour
4. The printing process is completely mechanized. As long as the precision of screen printing is high, the machine can restore 100% of the pattern without requiring highly skilled technicians.
5. No matter how many screen printing machines there are in the factory, as long as there is a master who adjusts the machine, the others are all ordinary workers, and the whole process can be operated.
