Working principle of screen printing machineTaking the commonly used hand screen plane screen printing machine as an example, the working principle of the screen printing machine can be described as follows: the power is transmitted through the transmission mechanism to make the ink scraper squeeze the ink and the screen printing plate in motion, so that the screen printing plate and the substrate form an embossing line.

The full-automatic gluing machine is a mechanical device that automatically completes the processes such as paperboard feeding, deviation correction, mark line shaping, gluing, folding, pressurization, alignment, counting and discharge at one time. Its characteristics can reduce the dependence of carton enterprises on a large number of skilled carton gluing workers, save the workplace, and greatly improve the work efficiency and product quality. 

The static maintenance of printing press refers to the maintenance of the machine under the static state of the machine.1. Establish rules and regulations for machine maintenance. The maintenance of offset press shall be subject to the instructions of the machine. Such as regular oil change, filter cleaning, regular testing of machine accuracy, etc.2. Strengthen the maintenance of important parts. Gears, cams, sprockets, rollers and bearings are important parts of the printing press. 

The dynamic maintenance of printing press refers to the maintenance of the machine when the printing press is in a dynamic state. Machine static maintenance is the premise of machine dynamic maintenance. At the same time, the dynamic operation of the machine can in turn detect the level of machine static maintenance. The dynamic maintenance of the machine is very important. The following analyzes the main contents that should be maintained under the dynamic condition of the machine from several aspects.

1. Ensure that the aircraft receiver is responsible for supervising the machinery, equipment and crew operators.2. Before operation, the operators shall wear work clothes, work hats and work shoes neatly, fasten the skirt and cuffs, and do not put sundries that are easy to fall out in the pocket, and do not wear watches and various accessories.3. Before starting the machine, add the required lubricating oil (grease) to each oil filling point, lubricating point and oil tank of the machine.

Single sided corrugating machine is facing eliminationSince the development of single-sided machine, due to its low grade, it can not guarantee the quality of cartons, so it is facing elimination.In the early 1990s, the agency issued a quality license for export carton packaging and believed that the single-sided machine could ensure the carton quality, which was still a decision made from reality at that time.
