Description

Technical Field

[0001] The utility model belongs to the technical field of graphite processing, and particularly relates to a printing mechanism with adjustable printing pressure. Background Technique

[0002] A printing press is a machine for printing characters and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, printing, and paper feeding. Its working principle is that first, the characters and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with characters and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates, such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics, so as to reproduce the same printed matter as the printing plate. The invention and development of the printing press play an important role in the spread of human civilization and culture.

[0003] In the process of using existing printing presses, ink is generally first injected into the ink cartridge, and the ink is pumped out from the inside of the ink cartridge by an ink pump. Then, the ink is sprayed or brushed onto the printing roller. Since the ink cannot flow well inside the ink cartridge, the printing substances contained in the ink will settle slowly. After settling for a period of time, the printing substances contained in the extracted ink will gradually decrease, resulting in poor printing effects and thus inconvenient for people to use.

[0022] Such as Figures 1-6As shown in the figure, a printing mechanism with adjustable printing pressure includes a working box 1, support legs installed at the four corners of the bottom of the working box 1, and a bracket 2 installed on the top of the working box 1. An installation opening is provided at the top of the working box 1. A printing roller 4 whose top extends outside the installation opening is rotatably connected inside the working box 1. A scraper 5 that fits the printing roller 4 is installed on one inner wall of the installation opening. The scraper 5 is located on one side of the rotation direction of the printing roller 4. By providing the scraper 5, the excess ink on the printing roller 4 can be scraped off, and the scraped ink will directly drip into the working box 1. A pressure roller 3 that cooperates with the printing roller 4 is installed inside the bracket 2. Adjusting mechanisms for adjusting the height of the pressure roller 3 are installed on both sides of the bracket 2. The adjusting mechanism includes a moving groove 20 opened on the side wall of the bracket 2, a moving block 18 slidably connected in the moving groove 20, and an electric telescopic rod 19 installed on the inner wall of the top of the moving groove 20. The output end of the electric telescopic rod 19 is fixedly connected to the top of the moving block 18. Both the moving groove 20 and the moving block 18 are in a cross-shaped structure. The two ends of the pressure roller 3 are respectively rotatably connected to one side of the two moving blocks 18. When in use, not only can the height of the pressure roller 3 be adjusted according to the thickness of the printed article, but also the printing pressure generated by the pressure roller 3 on the printed article can be adjusted to improve the printing quality of the product. When it is necessary to raise the height of the pressure roller 3, the electric telescopic rod 19 will drive the pressure roller 3 to move upward. When it is necessary to lower the height of the pressure roller 3, the electric telescopic rod 19 will drive the pressure roller 3 to move downward. Two sets of stirring mechanisms are installed inside the working box 1. The stirring mechanism includes two mounting plates 6, a rotating rod 7 rotatably connected between the two mounting plates 6, and a plurality of stirring blades 8 installed outside the rotating rod 7. A rack 17 is installed inside the working box 1. A gear 15 that meshes with the rack 17 is installed outside the rotating rod 7. Moving mechanisms for driving the two sets of stirring mechanisms to move are installed on both sides of the working box 1. The moving mechanism includes a mounting ring 16 slidably connected to one side of the working box 1 and having a strip-shaped structure, a driving mechanism installed inside the mounting ring 16 for driving the mounting ring 16 to reciprocate, and mounting rods 22 installed at both ends of the mounting ring 16. The mounting rods 22 extend into the working box 1. The two corresponding mounting rods 22 are respectively fixedly connected to one side of the two corresponding mounting plates 6. A plurality of strip-shaped openings 21 are provided on the side wall of the working box 1. The plurality of mounting rods 22 are respectively located in the plurality of strip-shaped openings 21. The driving mechanism includes a rotating rod 9 rotatably connected to the inner wall of the working box 1 and extending outside the working box 1, a semi-gear 10 installed outside the rotating rod 9, and a plurality of teeth 11 installed on the inner walls of the top and bottom of the mounting ring 16 and cooperating with the semi-gear 10. A rotating motor 14 for driving the rotating rod 9 to rotate is installed outside the working box 1. The two ends of the printing roller 4 are respectively fixedly connected to one end of the two rotating rods 9. Two fixing blocks are installed outside the working box 1. A limiting rod 12 is installed between the two fixing blocks. Two limiting rings 13 fixedly connected to one side of the mounting ring 16 are sleeved outside the limiting rod 12.The mounting ring 16 can be limited by the provided limiting rod 12 and limiting ring 13.,

[0023] It should be noted that for the printing mechanism with adjustable printing pressure, when in use, ink is injected into the working box 1, and the bottom side of the printing roller 4 is immersed in the ink. When the rotating motor drives one of the rotating rods 9 to rotate, the printing roller 4 will rotate, thereby causing the other rotating rod 9 to rotate. When the printing roller 4 rotates, it will pick up the ink in the working box 1, thereby performing the printing work. When the rotating rod 9 rotates, it will drive the semi-gear 10 to rotate. With the cooperation of the semi-gear 10 and multiple teeth 11, the mounting ring 16 will perform reciprocating left and right movements. Driven by the mounting ring 16, the mounting rods 22 at both ends of the mounting ring 16 will continuously perform reciprocating movements, thereby driving the two rotating rods 7 to perform reciprocating movements inside the working box 1. When the rotating rod 7 moves, it will drive the gear 15 to move. With the cooperation of the gear 15 and the rack 17, when the rotating rod 7 moves, the rotating rod 7 will rotate, thereby driving multiple stirring blades 8 to rotate. When the multiple stirring blades 8 perform reciprocating movements inside the working box 1, they will rotate, thereby stirring the ink inside the working box 1 and reducing the precipitation of printing substances in the ink, which may lead to poor printing effects.

[0024] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
