Description
Technical Field
[0001] The utility model relates to the technical field of printing equipment, in particular to a printing mechanism which is convenient for adjusting a gap and an ink application amount. Background Art
[0002] Printing equipment is a mechanical device used for printing work, which can be used to produce various printed materials, such as books, magazines, posters, business cards, etc. There are many types of printing equipment, including offset printing presses, gravure printing presses, letterpress printing presses, digital printing presses, etc. These devices are usually composed of parts such as printing plates, printing blankets, ink trays and embossing mechanisms. The printing process is completed by covering the printing material with ink or pigment and then transferring the pattern or text to another material.
[0003] In the existing technology, printing quality and precision are important indicators for evaluating the performance of printing equipment. Traditional printing mechanisms lack the function of accurately adjusting the tension and flatness of paper. The paper is prone to loosening or being too tight during the printing process, affecting the printing effect and quality. In addition, the contact pressure between the printing roller and the printing plate cannot usually be accurately adjusted, resulting in uneven pressure during the printing process for printing materials of different types and thicknesses, large differences in printing effects, and unstable printing quality, which is particularly significant in high-speed, large-volume printing tasks.

[0007] As a preferred embodiment, a screw rod is provided on the top side of the table plate, and the top side of the table plate is movably connected to the bottom end of the screw rod.
[0008] As a preferred implementation, a rectangular frame is provided on the top side of the platform, and the top of the platform is fixedly connected to the bottom end of the rectangular frame.
[0009] As a preferred embodiment, the inner wall of the rectangular frame is vertically slidably connected to the outer sides of one end of the movable roller 1 and the movable roller 2.
[0010] As a preferred implementation, a packaging roller is disposed on the top side of the platform, and the top side of the platform is fixedly connected to one end of the side surface of the packaging roller.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] 1. By rotating the screw rod, the movable roller 1 and the movable roller 2 will move in different directions, one up and the other down, and the size of the gap between them can be adjusted, and the tension of the paper will also change. This change in tension can affect the flatness and stability of the paper during printing.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1
[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a printing mechanism that is convenient for adjusting the gap and the amount of ink applied, comprising: an adjusting mechanism 1, an auxiliary mechanism 2 is arranged on the top side of the adjusting mechanism 1, a table 11 is arranged on the top side of the adjusting mechanism 1, a main frame 12 is arranged on the top side of the table 11, the top side of the table 11 is fixedly connected to the top side of the main frame 12, a movable plate 13 is arranged on the inner wall of the main frame 12, the inner wall of the main frame 12 is slidably connected to one side of the movable plate 13, a telescopic rod 14 is arranged at one end of the movable plate 13, one end of the movable plate 13 is fixedly connected to one end of the telescopic rod 14, the other end of the telescopic rod 14 is fixedly connected to the inner wall of the main frame 12, a roller 111 is arranged at one end of the movable plate 13, one end of the movable plate 13 is slidably contacted with the outer side of the roller 111, and the inner wall of the roller 111 is provided with a folding arm 15 The inner wall of the roller 111 is movably connected with one end of the folding arm 15, a screw rod 17 is provided on the top side of the table 11, and the top side of the table 11 is movably connected with the bottom end of the screw rod 17, a rectangular frame 110 is provided on the top side of the table 11, the top of the table 11 is fixedly connected with the bottom end of the rectangular frame 110, the inner wall of the rectangular frame 110 is vertically slidably connected with the outer side of one end of the movable roller 18 and the movable roller 2 19, a packaging roller 112 is provided on the top side of the table 11, and the top side of the table 11 is fixedly connected with one end of the side of the packaging roller 112, a printing roller 16 is provided at the bottom end of the folding arm 15, and the bottom end of the folding arm 15 is movably connected with one end of the printing roller 16, and the outer side of the screw rod 17 is respectively provided with movable roller 18 and movable roller 2 19, and the outer side of the screw rod 17 is threadedly connected with one end of the movable roller 18 and the movable roller 2 19.
[0026] In this embodiment, when the printing mechanism of this type is used, the paper is passed through the movable roller 18 and the movable roller 2 19 in an S-shaped route. At this time, by rotating the screw rod 17, the movable roller 18 and the movable roller 2 19 will move in different directions, one up and the other down, so that the size of the gap between them can be adjusted, and the tension of the paper will also change. This change in tension can affect the flatness and stability of the paper during printing, and thus affect the printing quality and accuracy; then the paper will contact the printing roller 16. In order to be able to control the printing pressure as required, the telescopic rod 14 is retracted so that the movable plate 13 moves under its action and contacts the folding arm 15. Since the end position of the movable plate 13 has a certain slope, the folding arm 15 will move downward according to the influence of the slope after contact, thereby adjusting the contact force between the printing roller 16 and the printing plate, thereby adjusting the printing pressure.

[0029] In this embodiment, a cavity 21 is installed behind the printing roller 16, and a heating tube 22 is designed in the cavity 21. After the paper is printed, it will pass through the cavity 21, which can provide heat to increase the air temperature. When the printed matter passes through the cavity 21, the hot air can accelerate the ink drying process on the surface of the printed matter. This helps to reduce the ink smearing, blurring or stains on the surface of the printed matter, improve the quality and appearance of the printed matter, and for certain types of ink, especially coating-type ink, the curing process of the ink can be promoted after heating. This can speed up the processing time of the printed matter, reduce the production cycle, and improve the durability and glossiness of the printed matter.
[0030] Working principle:
[0031] like Figure 1-Figure 4 As shown, the paper is passed through the movable roller 18 and the movable roller 2 19 in an S-shaped route. At this time, by rotating the screw rod 17, the movable roller 18 and the movable roller 2 19 will move in different directions, one up and the other down, so that the gap between them can be adjusted, and the tension of the paper will also change. This change in tension can affect the flatness and stability of the paper during printing, and further affect the printing quality and accuracy; then the paper will contact the printing roller 16. In order to be able to control the printing pressure as required, the telescopic rod 14 is retracted, so that the movable plate 13 will move under its action and contact with the folding arm 15. Since the end position of the movable plate 13 has a certain slope, the folding arm 15 will move downward according to the influence of the slope after contact, thereby adjusting the contact force between the printing roller 16 and the printing plate;
[0032] A cavity 21 is installed behind the printing roller 16, and a heating tube 22 is designed in the cavity 21. After the paper is printed, it will pass through the cavity 21, which can provide heat to increase the air temperature. When the printed matter passes through the cavity 21, the hot air can accelerate the drying process of the ink on the surface of the printed matter. This helps to reduce the ink smearing, blurring or stains on the surface of the printed matter, and improve the quality and appearance of the printed matter.
