Description

Technical Field

[0001] This utility model relates to the field of rubbing technology, and in particular to a manual rubbing device for woodblock New Year pictures. Background Technology

[0002] Rubbing is a handmade reproduction of a carved or stone-carved surface. The method involves tightly covering the artwork with a sheet of paper and then applying a black or colored material to create the rubbing. Traditional rubbing materials include Xuan paper and a block of black material called rubbing wax. Sometimes, especially when rubbing fine lines, an alternative method is preferred: applying powdered graphite to the paper with oil until it reaches a certain dry hardness before using an ink applicator.

[0003] In traditional hand-printing, the application of pressure relies heavily on manual experience, making it difficult to ensure consistent pressure for each print and resulting in inconsistent print quality. This is especially problematic when dealing with large areas or intricate designs, as uneven pressure can lead to blurred or missing ink marks. Furthermore, the lack of an effective cushioning mechanism during hand-printing means that direct pressure can easily cause the paper to tear or deform; this risk is even more pronounced when using fragile or precious paper. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a manual printing device for woodblock New Year pictures, which can effectively solve the aforementioned problems.

[0005] To achieve the above requirements, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A hand-printing device for woodblock New Year pictures is provided, including a printing table. A lifting top cover is mounted on the top of the printing table. An ink roller for printing is mounted on the bottom surface of the lifting top cover. A support base for supporting the woodblock New Year picture is located directly below the ink roller and on the top surface of the printing table. A base plate is fixedly attached to the bottom surface of the support base. An arc-shaped elastic arch plate is integrally formed in the middle of the top surface of the support base. A buffer cavity is provided between the arc-shaped elastic arch plate and the base plate. An arc-shaped silicone filling block is specifically filled in the buffer cavity. Multiple springs are embedded inside the arc-shaped silicone filling block. The upper and lower ends of each spring elastically abut against the inner walls of the arc-shaped elastic arch plate and the base plate, respectively. The arc-shaped elastic arch plate is located directly below the ink roller. Both ends of the printing table have anti-wrinkle positioning components for positioning the woodblock New Year picture during printing.

[0007] In this preferred embodiment, both ends of the printing table are fixed with inverted U-shaped positioning frames, and each U-shaped positioning frame has a groove in the middle of its top surface, with a positioning crossbar fixed in the groove.

[0008] In a preferred embodiment of this solution, the anti-wrinkle positioning component includes two positioning sliders symmetrically slidably connected in a groove and penetrated by a positioning crossbar, and a positioning roller rotatably installed below the positioning sliders. The positioning roller makes rolling friction contact with both ends of the woodblock New Year picture paper on the top surface of the support base.

[0009] In this preferred embodiment, the positioning slider is dynamically connected to the positioning crossbar via a locking bolt.

[0010] In a preferred embodiment, the top surface of the printing table is symmetrically welded with fixed uprights on both sides. Each fixed upright has a second hydraulic lifting rod fixed at the middle position of its top surface, and the top of the second hydraulic lifting rod is fixedly connected to the bottom surface of the lifting cover.

[0011] In this preferred embodiment, positioning rods are welded to both sides of the second hydraulic lifting rod and to the bottom surfaces of both ends of the lifting top cover. The positioning rods are longitudinally inserted into the fixed upright plate for positioning the lifting top cover during lifting.

[0012] In a preferred embodiment, a first hydraulic lifting column is longitudinally fixed at the middle position of the bottom surface of the lifting top cover, and an inverted U-shaped lifting plate is fixed at the bottom lifting end of the first hydraulic lifting column, with the ink brush roller being rotatably installed in the U-shaped lifting plate.

[0013] In a preferred embodiment of this design, a motor is installed on one side of the outer wall of the U-shaped lifting plate, and the output shaft of the motor passes through the U-shaped lifting plate and is connected to the ink roller.

[0014] In this preferred embodiment, each of the fixed upright plates has a longitudinally formed limit travel groove, and the other outer wall of the U-shaped lifting plate and the outer wall of the motor are both equipped with limit travel blocks.

[0015] In this preferred embodiment, the two limiting stroke blocks are respectively adapted and connected to adjacent limiting stroke slots. An operation control box is located on one side of the bottom surface of the printing table.

[0016] The beneficial effects of this utility model are as follows:

[0017] The manual printing device for woodblock New Year pictures utilizes an elastic arched plate, an arc-shaped silicone filler block, and spring components. This elasticity provides a cushioning effect when the ink roller presses down, ensuring even pressure distribution. This not only improves the quality of the printing but also prevents paper damage caused by excessive pressure. The woodblock New Year picture paper arches when it adheres to the support base, helping it to better fit the woodblock and improving the accuracy and clarity of the printing.

[0018] Positioning sliders and rollers are used to position both ends of the woodblock New Year picture paper, preventing the paper from slipping or wrinkling during the printing process. This design is particularly suitable for large-sized woodblock New Year picture papers, ensuring flatness throughout the printing process. Attached Figure Description

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This embodiment discloses, as follows: Figures 1 to 4The illustrated manual printing device for woodblock New Year pictures includes a printing table 1, a lifting top cover 3 mounted on top of the printing table, an ink roller 8 for printing mounted on the bottom surface of the lifting top cover 3, and a support base 4 for supporting the woodblock New Year picture on the top surface of the printing table 1 directly below the ink roller 8. The support base 4 is used to support the woodblock New Year picture paper and works together with the arc-shaped elastic arch plate 20, the buffer cavity 21, the arc-shaped silicone filling block 22 and the spring 24 to provide appropriate support and elastic buffer for the woodblock New Year picture paper, so as to avoid damage to the paper due to excessive pressure. A base plate 19 is fixedly attached to the bottom surface of the support base 4. An arc-shaped elastic arch plate 20 is integrally formed in the middle of the top surface of the support base 4. A buffer cavity 21 is provided between the arc-shaped elastic arch plate 20 and the base plate 19. An arc-shaped silicone filling block 22 is specifically installed in the buffer cavity 21. Multiple springs 24 are embedded inside the arc-shaped silicone filling block 22. The upper and lower ends of each spring 24 elastically abut against the inner walls of the arc-shaped elastic arch plate 20 and the base plate 19, respectively. The arc-shaped elastic arch plate 20 is located directly below the ink roller 8. Both ends of the printing table 1 have anti-wrinkle positioning components for positioning the woodblock New Year picture printing. The arc-shaped elastic arch plate 20, the buffer cavity 21, the arc-shaped silicone filling block 22, and the springs 24 together constitute an elastic support system that can withstand the pressure of the ink roller 8 and quickly return to its original shape after printing, protecting the woodblock New Year picture paper from damage and helping to improve printing quality and efficiency.

[0034] In this embodiment, the top surface of the arc-shaped silicone filler block 22 is provided with multiple mounting holes 23 for installing the spring component 24. The woodblock New Year picture is laid on the top surface of the support base 4. The woodblock New Year picture located on the top surface of the arc-shaped elastic arch plate 20 is attached to the arc-shaped elastic arch plate 20 and is in an arched state. When the ink roller 8 descends and prints on the woodblock New Year picture paper on the top surface of the support base 4, it will apply downward pressure. The design of the arc-shaped elastic arch plate 20, the arc-shaped silicone filler block 22 and the spring component 24 can provide a buffer effect for the ink roller 8 and the woodblock New Year picture paper to press down and print. At the same time, the woodblock New Year picture paper can bounce up to prevent damage to the woodblock New Year picture paper. In addition, with the anti-wrinkle positioning component, when the middle of the woodblock New Year picture paper is pressed down and printed, the two ends will slide towards the center. The anti-wrinkle positioning component positions the two ends of the woodblock New Year picture paper to prevent wrinkles.

[0035] In this embodiment, both ends of the printing table 1 are fixed with inverted U-shaped positioning frames 6. Each U-shaped positioning frame 6 has a groove 15 in the middle of its top surface, and a positioning crossbar 16 is fixed in the groove 15.

[0036] In this embodiment, the anti-wrinkle positioning component includes two symmetrically slidably connected positioning sliders 17 in the slide groove 15, which are penetrated by the positioning crossbar 16, and a positioning roller 7 rotatably mounted below the positioning sliders 17. The positioning roller 7 makes rolling friction contact with both ends of the woodblock New Year picture paper on the top surface of the support base 4. The positioning roller 7 is mounted below the positioning sliders 17 and contacts the woodblock New Year picture paper. Through rolling friction, it helps the paper to be laid flat and prevents wrinkles from forming. The slide groove 15 is provided on the U-shaped positioning frame 6, providing a moving track for the positioning sliders 17, ensuring that the positioning roller 7 can move smoothly along the length direction of the woodblock New Year picture paper.

[0037] In this embodiment, the positioning slider 17 is dynamically connected to the positioning crossbar 16 via a locking bolt 18. The positioning crossbar 16 passes through the positioning slider 17 and is connected to it via the locking bolt 18, and is used to adjust the position of the positioning roller 7 to adapt to different sizes of woodblock New Year picture paper.

[0038] In this embodiment, fixed upright plates 2 are symmetrically welded to the two sides of the top surface of the printing table 1. A second hydraulic lifting rod 12 is fixed at the middle position of the top surface of each fixed upright plate 2. The top end of the second hydraulic lifting rod 12 is fixedly connected to the bottom surface of the lifting top cover 3.

[0039] In this embodiment, positioning rods 11 are welded to both sides of the second hydraulic lifting rod 12 and to the bottom surfaces of both ends of the lifting cover 3. The positioning rods 11 are longitudinally inserted into the fixed upright plate 2 for positioning the lifting cover 3 during lifting. The positioning rods 11 are fixed to both ends of the lifting cover 3 and inserted into the fixed upright plate 2 to ensure the stability of the lifting cover 3 during lifting. The second hydraulic lifting rod 12 is installed on the top of the fixed upright plate 2 and is used for the lifting action of the lifting cover 3, providing power support.

[0040] In this embodiment, a first hydraulic lifting column 10 is longitudinally fixed at the center of the bottom surface of the lifting top cover 3. An inverted U-shaped lifting plate 9 is fixed at the bottom lifting end of the first hydraulic lifting column 10, and the ink brush roller 8 is rotatably installed in the U-shaped lifting plate 9. The ink brush roller 8, installed in the U-shaped lifting plate 9, is responsible for evenly coating the ink onto the wooden board and is a key working component in the printing process. The first hydraulic lifting column 10 controls the lifting and lowering movements of the U-shaped lifting plate 9 and the ink brush roller 8 on it, thereby achieving fine adjustment of the printing depth.

[0041] In this embodiment, a motor is installed on one side of the outer wall of the U-shaped lifting plate 9, and the output shaft of the motor passes through the U-shaped lifting plate 9 and is connected to the ink roller 8.

[0042] In this embodiment, each fixed upright plate 2 has a longitudinally provided limit travel groove 13, and the other side outer wall of the U-shaped lifting plate 9 and the outer wall of the motor are both equipped with limit travel blocks 14.

[0043] In this embodiment, two limit travel blocks 14 are respectively adapted and connected to adjacent limit travel slots 13. The limit travel slots 13 and limit travel blocks 14 work together to limit the maximum travel of the lifting top cover 3 and the U-shaped lifting plate 9, preventing excessive lifting and lowering from damaging the equipment. One side of the bottom surface of the printing table 1 has an operation control box 5, which contains a PLC for controlling the opening and closing of various devices.

[0044] Working principle:

[0045] The manual printing device for woodblock New Year pictures is placed on a flat workbench to ensure stability. Prepare the woodblock New Year picture paper and ink. Cut the woodblock New Year picture paper to a suitable size, ensuring it fits the support base 4. Lay the woodblock New Year picture paper flat on the top surface of the support base 4, ensuring the paper completely covers the curved elastic arch plate 20. Due to the design of the curved elastic arch plate 20, the woodblock New Year picture paper will naturally exhibit a slight arch, which facilitates the subsequent printing process.

[0046] Slide the positioning slider 17 to move it to the appropriate position along the slide groove 15, ensuring that the positioning roller 7 can contact both ends of the woodblock New Year picture paper. Use the locking bolt 18 to fix the positioning slider 17, ensuring that the positioning roller 7 can firmly press down on both ends of the woodblock New Year picture paper to prevent wrinkles from forming during the printing process.

[0047] Open the operation control box 5, start the equipment via the PLC control system, and control the second hydraulic lifting rod 12 to rise, thereby raising the lifting top cover 3 to the predetermined height, ensuring sufficient space for subsequent operations. Apply ink evenly to the wooden board, ensuring uniform ink distribution. Place the ink-coated wooden board on top of the woodblock New Year picture paper, ensuring both are aligned.

[0048] The first hydraulic lifting column 10 is controlled to descend, which in turn drives the U-shaped lifting plate 9 and the ink brush roller 8 to descend together. When the ink brush roller 8 contacts the woodblock New Year picture paper, it continues to descend slowly until the ink brush roller 8 applies appropriate pressure to the woodblock New Year picture paper.

[0049] Driven by a motor, the ink roller 8 rotates to evenly print on the woodblock New Year picture paper. The elastic system consisting of the arc-shaped elastic arch plate 20, the arc-shaped silicone filler block 22, and the spring 24 acts as a buffer during this process, ensuring even pressure distribution and preventing paper damage. At the same time, the positioning roller 7 positions the two ends of the woodblock New Year picture paper to prevent the paper from slipping or wrinkling.

[0050] After the printing is completed, control the first hydraulic lifting column 10 to rise, driving the U-shaped lifting plate 9 and the ink roller 8 to rise together and return to the initial position. The spring component 24 quickly returns to its original shape after the pressure is released, helping the woodblock New Year picture paper to spring back and maintain its flatness. Adjust the positioning slider 17, loosen the locking bolt 18, and remove the positioning roller 7 from the woodblock New Year picture paper. Carefully remove the printed woodblock New Year picture paper, check the printing effect, and ensure there are no wrinkles or damage.

[0051] Clean the support base 4 and the ink roller 8 to ensure the equipment is clean and tidy, preparing it for the next printing. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
