Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a decorative paper printing device. 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 mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press. Then, the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] A decorative paper printing device mentioned in an existing Chinese public patent (authorization announcement number: CN217968928U). It includes a printing roller and a scraper box arranged directly below the printing roller, and scrapers 1 and 2 are fixedly connected to the groove edges on both sides of the scraper box, respectively. The gap between scraper 1 and the printing roller is smaller than the gap between scraper 2 and the printing roller. Both ends of the printing roller are connected to an ink absorbing mechanism in an integral structure, and the ink absorbing end plates included in the ink absorbing mechanism are respectively in conflict with the two ends of scraper 1 and scraper 2. By adopting this technical solution, scraper 1 and scraper 2 buffer the extrusion force of the ink applied by the scraping roller, and can make the ink applied by the scraping roller enter the scraper box, so as to avoid the splashing of the scraped ink; and the ink released by scraper 1 and scraper 2 to the two ends is easy to be absorbed by the ink absorbing end plates, thereby avoiding the splashing of the ink at the two ends of scraper 1 and scraper 2.

[0004] When the existing device prints the decorative paper, it is necessary to apply ink to the surface of the decorative paper through the printing roller. However, when the existing decorative paper is printed, the dust on the surface of the decorative paper will affect the printing process of the printing roller, which will easily loosen the ink and cause printing errors of the decorative paper. Utility Model Content

[0005] The purpose of the present application is to solve the problem that dust on the surface of the existing decorative paper may affect the printing process of the printing roller and easily cause the ink to loosen. The present application provides a decorative paper printing device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0010] By adopting the above technical solution, the ink on the roller is scraped more evenly by the scraper, and the excess ink moves to the ink collection box through the drainage plate as the roller rotates, further enhancing the ink adhesion effect of the device when printing on decorative paper.

[0011] Furthermore, a spring is sleeved on the sliding column, and two ends of the spring are respectively fixedly connected to the ink receiving box and the blanking plate.

[0012] By adopting the above technical solution, the ink collecting box is pulled toward the roller through the resetting of the spring, driving the scraper to fit the surface of the roller.

[0013] Furthermore, a fan is fixedly connected to the machine body, an air duct is fixedly connected to the fan, and an air outlet is fixedly connected to the end of the air duct.

[0014] By adopting the above technical solution, the fan is started to spray air from the air outlet through the air duct to blow the surface of the decorative paper, thereby reducing impurities such as dust attached to the surface of the decorative paper.

[0015] Furthermore, a movable threaded rod is rotatably connected to the machine body, and the movable threaded rod is threadedly connected to the air outlet. A movable motor is fixedly connected to the machine body, and the output end of the movable motor is threadedly fixedly connected to the movable threaded rod. A feeding motor is fixedly connected to the machine body, and a material roller is fixedly connected to the output end of the feeding motor, and the material roller is rotatably connected to the machine body.

[0016] By adopting the above technical solution, the feeding motor is started to drive the material roller to rotate, so that the decorative paper moves between the pressure roller and the cylinder. At the same time, the moving motor is started to drive the moving threaded rod to rotate, so that the air outlet moves and the air outlet position is adjusted, so that there are fewer blind spots for cleaning the paper.

[0017] Furthermore, a limiting column is fixedly connected to the machine body, and the limiting column is slidably connected to the air outlet.

[0018] By adopting the above technical solution, the air outlet moves along the limiting column, so that the air outlet is more stable during the process of cleaning the paper.

[0019] Furthermore, a bidirectional threaded rod is rotatably connected to the machine body, an adjusting motor is fixedly connected to the machine body, an output end of the adjusting motor is fixedly connected to the adjusting motor, and the bidirectional threaded rod is threadedly connected to both the loading plate and the unloading plate.

[0020] By adopting the above technical solution, the adjusting motor is started to drive the bidirectional threaded rod to rotate, so that the loading plate and the unloading plate move toward each other or in the same direction, driving the distance adjustment between the pressure roller and the drum, which facilitates the device to print papers of different thicknesses.

[0021] Furthermore, a guide column is fixedly connected to the machine body, and the guide column is slidably connected to both the loading plate and the unloading plate.

[0022] By adopting the above technical solution, the loading plate and the unloading plate move toward each other or in the same direction along the guide column, making it more stable when adjusting the distance.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the device is used to print decorative paper, the feeding motor is first started to drive the material roller to rotate, so that the decorative paper moves between the pressure roller and the drum. At the same time, the moving motor is started to drive the moving threaded rod to rotate, so that the air outlet moves along the limiting column.

The ink collecting box is pulled toward the drum by the reset of the spring, driving the scraper to fit the surface of the drum, so that the ink on the drum is scraped more evenly by the scraper, and the excess ink will move to the ink collecting box through the guide plate as the drum rotates, further enhancing the ink adhesion effect of the device when printing on the decorative paper, so that the device can only be more effective during use.

[0025] 2. In the present application, when the device is used to process decorative papers of different sizes, the adjusting motor is started to drive the bidirectional threaded rod to rotate, so that the loading plate and the unloading plate move toward each other or in the same direction along the guide column, driving the distance adjustment between the pressure roller and the cylinder, thereby facilitating the process of printing papers of different thicknesses, making the device more convenient when used for printing.
