Description

Technical Field

[0001] This invention belongs to the field of color printing technology, and specifically relates to a scrolling color printing method. Background Technology

[0002] Color printing refers to printing on a single printing plate using different colored plates in sequence, creating a color image effect through the superposition of multiple colors. This technology involves processes such as plate making, inking, and pressure application to transfer ink from original text, pictures, photographs, etc., to the surface of materials such as paper, textiles, and leather, enabling mass reproduction of the original content. Currently, color printing commonly uses offset printing. Existing technologies for manual color printing are relatively inefficient because they typically use at least two rolling printing presses for batch printing. Furthermore, because it is manual printing, the patterns on the rolling presses must perfectly match to ensure optimal printing results, resulting in inconsistent print quality. Additionally, the use of multiple rolling presses makes carrying and storage inconvenient. Therefore, it is necessary to improve existing technologies. Summary of the Invention

Detailed Implementation

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0018] Example: like Figures 1-4 As shown, this embodiment provides a rolling color printing system, including a printing roller 1, a main housing 2, and a rotating connecting mechanism. The printing roller 1 is provided in at least two, and can be two, three, or more, depending on the design requirements. This embodiment uses... Figures 1-4Taking the four printing rollers 1 as an example, all printing rollers 1 are arranged in parallel so that the rolling direction of all printing rollers 1 can be kept consistent. This allows the patterns on all printing rollers 1 to match during printing. For example, after the pattern on the first printing roller 1 is printed on the paper, the pattern on the second printing roller 1 can correspond to the pattern printed on the paper by the first printing roller 1. Through two or more printings, the effect of color printing is achieved. Any two adjacent printing rollers 1 are spaced apart so that they will not affect each other's rolling during printing, nor will the colors on the two printing rollers 1 mix together, thus affecting the color printing effect. This also makes it convenient to use all printing rollers 1 in coordination for color printing.

[0019] For the main housing 2, all printing rollers 1 are rotatably connected to the bottom of the main housing 2, such as... Figure 1 and Figure 2 As shown, all the printing rollers 1 are assembled together by means of the main housing 2. This eliminates the need to set up multiple rollers for color printing, saving materials and thus reducing costs. The positions of all the printing rollers 1 can also be positioned, so that all the printing rollers 1 can be precisely matched during printing by pre-setting, thereby ensuring the quality of color printing. In addition, the bottom surface of each printing roller 1 is lower than the bottom surface of the paper in the horizontal direction, so that when the whole is set downwards, the printing roller 1 can contact the paper, etc. The main housing 2 controls all the printing rollers 1 to perform color printing. For example, when the printing roller 1 is at the bottom, the printing roller 1 will contact the fixed paper, and then when it moves on the paper, the printing roller 1 can print on the paper.

[0020] Regarding the rotary connection mechanism, all printing rollers 1 are connected through the rotary connection mechanism, so that all printing rollers 1 can rotate synchronously. Therefore, when printing using the rolling color printing of the present invention, by ensuring that all printing rollers 1 rotate synchronously, the coordination effect of all printing rollers 1 can be guaranteed, and the color printing quality can be guaranteed.

[0021] This invention rotatably connects at least two printing rollers 1 to the bottom of the main housing 2. A rotating connection mechanism enables all printing rollers 1 to rotate synchronously. During color printing, only the main housing 2 needs to be controlled to simultaneously control all printing rollers 1 to roll on the paper, ensuring the precision of the fit between all printing rollers 1 and thus guaranteeing the final color printing quality. Furthermore, by mounting all the printing rollers 1 required for color printing at the bottom of the main housing 2, color printing can be completed with a single operation, improving printing efficiency. Compared to multiple separate rolling printing rollers, this invention also saves material costs and is more convenient to carry and store.

[0022] As a preferred embodiment of this invention, it should be further explained that a printing roller clearance groove is provided in the middle of the main housing 2. Preferably, the main housing 2 is a hollow housing with a printing roller clearance groove in the middle. The printing roller 1 generally includes a roller shaft 101 and an impression cylinder. The rotating shafts at both ends of the printing roller 1 are both set on the roller shaft 101, so that the two ends of the roller shaft 101 can be stably rotatably connected to the main housing 2, realizing the rotational connection of the printing roller 1 at the bottom of the main housing 2, ensuring the overall flexibility. An annular groove is provided in the middle of the roller shaft 101, and the middle of the printing roller 1 is set in the printing roller clearance groove. Specifically, the impression cylinder is matched and installed in the annular groove to facilitate printing. The part where the impression cylinder is located is located at the position of the printing roller clearance groove, which facilitates the impression cylinder to print on the paper as it rotates. Meanwhile, at least two limiting installation grooves are provided on the side walls on both sides of the printing roller clearance groove, and rotating shafts are provided at both ends of the printing roller 1. The two rotating shafts are matched and rotated in a limiting installation groove, so as to realize the rotational connection of the printing roller 1 on the main housing 2.

[0023] As a preferred embodiment of this invention, it should be further explained that the limiting mounting groove opening is configured such that each rotating shaft passes through the opening and is detachably mounted within the limiting mounting groove, facilitating the loading and unloading of the printing roller 1. This allows for convenient selection of the number of printing rollers 1 and printing rollers 1 with different patterns and colors according to actual conditions, ensuring flexibility. The rotating connection mechanism includes a first gear 3 and a second gear 4. A second gear 4 is mounted on the rotating shaft at the same end of all printing rollers 1. Any two adjacent second gears 4 mesh with the first gear 3. The first gear 3 is rotatably connected to the main housing 2 inside the printing roller clearance groove, enabling all printing rollers 1 to rotate synchronously using the first gear 3 and the second gear 4. The transmission method is simple and practical. The second gear 4 can be a gear mounted alone on the rotating shaft or multiple meshing teeth arranged in a circular array on the rotating shaft; the design can be tailored to the specific situation and is not specifically limited. This embodiment provides... Figure 3 and Figure 4 The second gear 4 shown consists of multiple meshing teeth arranged in a ring array on the rotating shaft.

[0024] It should be noted that when it is necessary to disassemble a printing roller 1, simply remove the rotating shafts at both ends of the printing roller 1 from the limiting mounting groove. Then, replace the printing roller 1 as needed. If the original printing roller 1 is not at the correct angle, remove the printing roller 1, rotate it at a certain angle, and then reassemble it. The operation is simple and convenient.

[0025] As a preferred embodiment of this invention, it should be further explained that the roller 101 includes a roller main body section 1011 and a roller disassembly section 1012 detachably connected to one end of the roller main body section 1011. The rotating shafts at both ends of the printing roller 1 are respectively disposed on the roller main body section 1011 and the roller disassembly section 1012, without affecting the overall detachable connection and the loading and unloading of the printing roller 1 on the main housing 2; the impression cylinder is installed at one end of the roller main body section 1011 near the roller disassembly section 1012, and the middle of the roller main body section 1011... The roller shaft is provided with a first limiting ring, and a second limiting ring is provided at one end of the roller shaft disassembly section 1012 near the roller shaft body section 1011. The impression cylinder is positioned between the first and second limiting rings. The stability of the impression cylinder is ensured by limiting the first and second limiting rings. It should be noted that the diameters of the first and second limiting rings are both smaller than the outer diameter of the impression cylinder, so they will not affect the printing of the impression cylinder. The second gear 4 is provided on the roller shaft disassembly section 1012 on the side of the second limiting ring away from the impression cylinder, and is matched with the first gear 3.

[0026] As a preferred embodiment of this invention, it should be further explained that the main body section 1011 and the disassembly section 1012 of the roller shaft are detachably connected by screws for easy assembly and disassembly. One end of the main body section 1011 is provided with a threaded connection hole 10111, and the disassembly section 1012 is provided with a stepped screw mounting hole 10121. The screw mounting hole 10121 passes through both ends of the disassembly section 1012. The screw shank passes through the screw mounting hole 10121 and is threaded into the threaded connection hole 10111. The screw nut abuts against the screw mounting hole 10121. Thus, when the screw is tightened, a stable connection between the main body section 1011 and the disassembly section 1012 of the roller shaft can be ensured. In this embodiment, it should be noted that when it is necessary to adjust the angle of an impression cylinder, the screw can be unscrewed, and then the adjacent printing roller 1 can be pressed to prevent it from rotating. Then the corresponding impression cylinder can be rotated, so that the roller shaft body section 1011 on which the impression cylinder is installed can rotate relative to the roller shaft disassembly section 1012. This can also realize the rotation adjustment of the impression cylinder, and at the same time make the rotation adjustment of the impression cylinder more flexible.

[0027] As a preferred embodiment of this invention, it should be further explained that the other end of the roller disassembly section 1012 is provided with a rubber plug 1013 that is tightly sealed to the end of the screw mounting hole 10121 to ensure sealing, thereby preventing the screw from getting damp and rusting, and also improving the aesthetic effect.

[0028] The rubber stopper 1013 is made of highly elastic rubber material, and its shape is adapted to the end shape of the screw mounting hole 10121. It can be tightly plugged into the end of the screw mounting hole 10121, effectively preventing external moisture from entering the screw mounting hole 10121. Moreover, this rubber stopper 1013 is easy to install and remove, and can be easily removed when the screw needs to be inspected or replaced.

[0029] As a preferred embodiment of this invention, it should be further noted that a flat adjusting plate 10112 is provided at the other end of the main body section 1011 of the roller shaft, which makes it more convenient and easier to operate when controlling the relative rotation of the main body section 1011 of the roller shaft and the disassembly section 1012 of the roller shaft.

[0030] As a preferred embodiment of this invention, it should be further explained that an annular limiting groove is provided at one end of the main body section 1011 of the roller shaft outside the threaded connection hole 10111, and an annular limiting part 10122 is provided on the roller shaft disassembly section 1012 on the other side of the second limiting ring. The annular limiting part 10122 is sleeved in the annular limiting groove, which can further improve the stability when the main body section 1011 of the roller shaft and the roller shaft disassembly section 1012 are connected together, and will not affect the relative rotation between the two.

[0031] As a preferred embodiment of this example, it should be further explained that the lower end of the main housing 2 is fastened with a bottom cover 5, and the middle part of all the printing rollers 1 is covered between the main housing 2 and the bottom cover 5. When not in use, the bottom cover 5 can be closed, which makes it more convenient to store and can also avoid damage to the printing rollers 1.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
