Description

Movable printing machine with cleaning function

Technical Field

The invention relates to the technical field of printing machines, in particular to a movable printing machine with a cleaning function.

Background

A modern printing machine for printing characters and images generally comprises mechanisms such as plate loading, inking, stamping, paper conveying and the like, and the working principle of the machine is as follows: the invention and development of the printing machine, which is important for the propagation of human civilization and culture, take a common hand screen plane screen printer as an example and can describe the working principle of the screen printing machine as follows: the power is transmitted by a transmission mechanism, the ink scraping plate extrudes the ink and the screen printing plate in the movement process, the screen printing plate and the printing stock form a press mark, the screen has the tension N1 and N2, the force F2 is generated on the ink scraping plate, the resilience force ensures that the screen printing plate does not contact with the printing stock except the press mark, the ink leaks to the printing stock from the moving press mark through the mesh under the action of the extrusion force F1 of the ink scraping plate, the screen printing plate and the ink scraping plate move relatively in the printing process, the extrusion force F1 and the resilience force F2 also move synchronously, the screen returns to be separated from the contact stock in time under the action of the resilience force so as to avoid smearing marks, namely the screen is continuously deformed and rebounded in the printing process, the ink scraping plate is separated from the printing stock after finishing the unidirectional printing, and the return ink is simultaneously carried out, namely a printing cycle is finished, the distance between the upper surface of the ink-returning printing-bearing object and the reverse side of the screen printing plate is called as the same plate distance or the screen distance, and generally ranges from 2 mm to 5mm, the formation of a press line is directly influenced by the manipulation and proficiency of an operator during manual printing, and a lot of precious experiences are accumulated by the screen printing worker in practice and can be specifically summarized into six points, namely, the straightness, the uniform speed, the equiangular performance, the pressure equalizing part, the centering performance and the vertical edge performance of the ink scraping plate during the movement of the ink scraping plate are ensured, namely, the ink scraping plate is required to advance linearly and cannot shake left and right during printing; the front is slow and the back is fast, and the front is fast and the back is slow or fast; the inclination angle to the ink plate should be kept constant, and special attention should be paid to overcoming the common fault that the inclination angle is gradually increased; the printing pressure is kept uniform and consistent; keeping the distances between the ink scraping plate and the two sides of the inner side of the screen frame equal; the ink plate is perpendicular to the frame.

However, during the printing, the ink often leaves over the board surface, when printing next time, leads to the printed matter back and the ink contact of leaving over, leads to printing quality to reduce, and it is more troublesome to change ink, directly pours into, leads to ink to spill easily.
