Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a printing machine with a positioning function. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

[0003] With the continuous development of science and technology, people are using printing presses more and more widely. By using printing presses, text and patterns can be copied onto substrates. With the continuous improvement of printing presses, the production efficiency of printing presses is also constantly improving, which plays a very important role in the spread of human civilization and culture.

[0004] The invention and development of printing presses play an important role in the dissemination of human civilization and culture. In order to meet people's demand for high-end color prints, multi-color group double-sided printing with eight or even ten color groups and additional online post-printing processing functions have become the development trend of various types of sheet-fed offset printing presses. Moreover, as the technology matures, this type of printing press has begun to occupy part of the market that originally belonged to web printing presses. Application number: CN202120492616.0 discloses a printing press with a positioning function. By controlling a relatively movable positioning plate, the printed cardboard is fixed at the center of the crawler, the printing effect is improved, and the printing press can adapt to packaging cardboards of different widths. However, when the device is in use, dust will accumulate on the surface of the paper when it is stored. The dust located at the place where printing is required will cause blurring, spots or uneven colors when printing, which greatly affects the visual effect of the printed product. The device lacks a dust removal function before printing and has poor adaptability.

[0005] Therefore, it is necessary to provide a printing press with a positioning function to solve the above technical problems. Utility Model Content

[0035] A collection box 8 is provided on the back of the machine body 1 , and supporting feet 9 are provided on both sides of the bottom of the machine body 1 .

[0036] The working principle of a printing machine with positioning function provided by the utility model is as follows:

[0037] Step 1: When in use, the electric push rod 35 drives the movable plate 32 to slide left and right inside the sliding groove 31 to adjust the distance between the movable plate 32 and the baffle 33, thereby adapting to the position limitation of papers of different lengths to prevent the paper from running off during printing;

[0038] Step 2: Place the paper to be printed on the conveyor belt 21, and drive the transmission rod 22 to rotate by the output end of the driving motor 26, and then drive the belt 25 to rotate. The cleaning brush roller 24 moves in the opposite direction to the paper, and then drives the cleaning brush roller 24 to rotate. The cleaning brush roller 24 rotates to brush away the dust on the surface of the paper, thereby improving the subsequent printing effect;

[0039] Step 3: After the paper is printed, the ink on it is often not dry. Direct collection at this time will affect the printing effect. The heating strip 7 and the hot fan 6 are used to dry the ink, which is convenient for subsequent collection.

[0040] Compared with the related art, the printer with positioning function provided by the utility model has the following beneficial effects:

[0041] The electric push rod 35 drives the movable plate 32 to slide left and right inside the sliding groove 31 to adjust the distance between the movable plate 32 and the baffle 33, thereby adapting to the limitation of papers of different lengths. The rotation of the output end of the driving motor 26 drives the transmission rod 22 to rotate, thereby driving the belt 25 to rotate. The cleaning brush roller 24 moves in the opposite direction to the paper, thereby driving the cleaning brush roller 24 to rotate. The cleaning brush roller 24 rotates to brush away the dust on the surface of the paper. The structure is simple and practical, effectively avoiding the influence of dust on the paper on printing, and improving the overall efficiency of the printing machine.
