Description

Technical Field

[0001] This utility model relates to the field of decorative paper printing technology, and in particular to a decorative paper printing apparatus. Background Technology

[0002] Decorative paper is an essential raw material in many building materials products, such as low-pressure and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. In the product structure, decorative paper mainly serves to provide decorative patterns and to cover and prevent the underlying adhesive from seeping through. This layer requires the paper to have good opacity, impregnation properties, and printability. Decorative paper requires a smooth surface, good absorbency and adaptability; for paper with a base color, the tone should be uniform; for colored paper, the colors should be vibrant. Therefore, printing on the decorative paper requires specific colors and patterns.

[0003] Decorative paper printing requires a printing device that transfers ink to the printing roller via an ink distribution roller, and then prints the decorative paper onto the printing roller. However, depending on the application requirements, the thickness of the decorative paper varies, so the distance between the printing roller and the support roller needs to be adjusted. Traditional devices adjust the height of the printing roller using a handwheel and a dial, requiring multiple people to observe the pressure and rely on experience to judge the depth of the paper indentation. This necessitates multiple adjustments to the height of the printing roller. Based on the above problems, this application proposes a decorative paper printing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a decorative paper printing apparatus to solve the problems mentioned in the background section.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-4A decorative paper printing device includes a mounting base plate 1, a mounting frame 2 fixedly mounted on the top of the mounting base plate 1, a hydraulic push rod 3 fixedly mounted on the top of the mounting frame 2, a pressure detection component at the output end of the hydraulic push rod 3, a mounting plate 11 mounted inside the mounting frame 2 via the pressure detection component, a printing component mounted inside the mounting plate 11, a spacing adjustment component mounted on the left side of the mounting plate 11, a support roller 24 rotatably mounted inside the mounting frame 2, the support roller 24 not contacting the mounting base plate 1, and a movable plate 5 fixedly mounted on the output end of the hydraulic push rod 3. A mounting groove 6 is provided through the top of the movable plate 5, a connecting plate 7 is slidably mounted inside the mounting groove 6, a limit plate 8 is fixedly mounted on the top of the connecting plate 7, and the bottom of the limit plate 8 is connected to the movable plate 5. The tops of the movable plates 5 overlap, and a pressure plate 9 is fixedly installed at the bottom of the connecting plate 7. A pressure sensor 10 is fixedly installed at the bottom of the movable plate 5. There are two connecting plates 7, which are symmetrically distributed. The connecting plates 7 are made of metal and have a rectangular structure, which keeps the pressure plate 9 moving vertically and prevents the pressure plate 9 from tilting, which would cause inaccurate readings from the pressure sensor 10. The detection end of the pressure sensor 10 is in contact with the pressure plate 9. The printing assembly includes a sliding plate 18 and a lower drive motor 22. The lower drive motor 22 is fixedly installed on the side of the mounting plate 11, and a printing roller 23 is fixedly installed at the output end of the lower drive motor 22. The sliding plate 18 is slidably installed inside the mounting plate 11 and has an I-shaped structure. The sliding plate 18 is made of metal, and a rectangular groove is provided on its surface for mounting the sliding plate 18, preventing it from falling off the mounting plate 11. This makes the upper drive motor 19 and the ink distribution roller 20 more securely mounted. The upper drive motor 19 is fixedly mounted on the side of the sliding plate 18, and the ink distribution roller 20 is fixedly mounted on the output end of the upper drive motor 19. The hydraulic push rod 3 drives the connecting plate 7 and the limiting plate 8 to move via the moving plate 5, so that the pressure plate 9 drives the sliding plate 18 and the lower drive motor 22 to move via the mounting plate 11. The mounting plate 11 drives the upper drive motor 19, the ink distribution roller 20, the lower drive motor 22, and the printing roller 23 to move, adjusting the distance between the printing roller 23 and the support roller 24. When the printing roller 23 comes into contact with the decorative paper, the forces are mutual, causing the decorative paper to exert the same push on the printing roller 23. This causes the printing roller 23 to exert an upward push on the pressure plate 9 via the mounting plate 11. The pressure sensor 10 detects the pressure received, which is the pressure applied by the printing roller 23 to the decorative paper. This allows printing on decorative paper of different thicknesses. Furthermore, the distance between the printing roller 23 and the support roller 24 can be controlled according to the printing pressure required for different thicknesses of decorative paper. This makes adjusting the distance between the printing roller 23 and the support roller 24 more convenient, avoiding the need for multiple adjustments to the height of the printing roller 23 via handwheels and dials.

[0021] Specifically, a guide rod 4 is fixedly installed on the top of the movable plate 5. The guide rod 4 is slidably installed inside the mounting frame 2. The guide rod 4 is a metal cylinder. The guide rod 4 can guide the movable plate 5 and prevent the movable plate 5 from tilting, which could cause the connection between the movable plate 5 and the hydraulic push rod 3 to break.

[0022] Specifically, the spacing adjustment assembly includes a fixed plate 12 and a rectangular plate 15 fixedly mounted on the side. A servo motor 13 is fixedly mounted on the top of the rectangular plate 15, and a lead screw 14 is fixedly mounted on the output end of the servo motor 13. The lead screw 14 is rotatably connected to the rectangular plate 15. A threaded sleeve 16 is threaded onto the surface of the rectangular plate 15. A movable column 17 is fixedly mounted on the right side of the threaded sleeve 16 and is fixedly connected to a sliding plate 18 on the left side. A laser distance detection sensor 21 is fixedly mounted inside the fixed plate 12. The laser distance detection sensor 21 is vertically aligned with the movable column 17. When the ink thickness needs to be changed, the output end of the servo motor 13 drives the lead screw 14 to rotate, and the lead screw 14 drives the lead screw... The sleeve 16 moves up or down, causing the silk sleeve 16 to drive the moving column 17 to move up or down. The moving column 17 then drives the sliding plate 18 to slide inside the mounting plate 11, causing the sliding plate 18 to drive the ink distribution roller 20 to move up or down. This adjusts the distance between the ink distribution roller 20 and the printing roller 23, thereby changing the thickness of the ink applied by the ink distribution roller 20 to the printing roller 23. The moving distance of the moving column 17 is detected by the laser distance detection sensor 21. When the ink distribution roller 20 is in contact with the printing roller 23, the reading of the laser distance detection sensor 21 is zero. This avoids the problem of adjusting the distance between the ink distribution roller 20 and the printing roller 23 by measuring point by point with a feeler gauge, which makes it difficult to ensure the uniformity of the entire roller and causes the ink amount deviation on the left and right sides.

[0023] The decorative paper printing device is connected to 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0024] In use: The decorative paper is unwound by an external unwinding device. When the decorative paper enters between the support roller 24 and the printing roller 23, the hydraulic push rod 3 drives the output end to move the moving plate 5 according to the thickness of the decorative paper. The moving plate 5 then moves the connecting plate 7 and the limiting plate 8, which in turn move the pressure plate 9. This causes the mounting plate 11 to move the sliding plate 18 and the lower drive motor 22. The mounting plate 11 then moves the upper drive motor 19 and the ink distribution roller 20, and the lower drive motor 22 moves the printing roller 23, adjusting the distance between the printing roller 23 and the support roller 24. When the printing roller 23 contacts the decorative paper, it applies ink to the paper. The pressure required for printing is such that, due to the mutual interaction of forces, the decorative paper exerts the same push on the printing roller 23, causing the printing roller 23 to exert an upward push on the pressure plate 9 via the mounting plate 11. This causes the pressure plate 9 to apply pressure to the detection end of the pressure sensor 10. The pressure sensor 10 detects the received pressure, which is the pressure exerted by the printing roller 23 on the decorative paper. This allows for printing on decorative papers of different thicknesses. Ink is transported to the ink distribution roller 20 through an external conveying pipe. The upper drive motor 19 drives the ink distribution roller 20 to rotate, causing it to deliver ink to the printing roller 23. The lower drive motor 22 drives the printing roller 23 to rotate, enabling it to print on the decorative paper.
