Description

Technical Field

[0001] This utility model relates to the field of rotary printing presses, specifically an automatic color-adjusting rotary printing press. Background Technology

[0002] Rotary printing presses, also known as web printing presses, use web paper as the printing material. The printing cylinders rotate continuously to transfer graphic information to the paper. The working principle is based on the selective ink adsorption characteristics of the printing plate: the blank areas of the printing plate are hydrophilic and ink-repellent, while the graphic areas are ink-repellent and water-repellent. The ink is indirectly transferred to the paper through the blanket, achieving efficient printing.

[0003] In existing technologies, rotary printing presses can effectively achieve printing for publications, packaging, commercial applications, and digital products, thus facilitating the subsequent use of printed objects. Generally, when using a rotary printing press, colored ink is printed onto the object by a dyeing roller. In some cases, when adjusting the printed color, the operator usually controls the extraction volume of the pump to adjust the color. However, when operating the pump, factors such as extraction time and extraction force can easily lead to a certain deviation between the final adjusted color and the desired color, thus affecting the color effect of the final printed product. Utility Model Content

[0004] To address the shortcomings of existing technologies, when operators manipulate the extraction pump, factors such as extraction time and force can easily lead to a deviation between the final adjusted color and the desired color, thus affecting the color effect of the final printed product. This utility model proposes an automatic color-adjusting rotary printing machine.

[0006] Preferably, the adjusting mechanism includes an extraction box, the inner cavity of which is fixedly connected to the surface of a connecting pipe. A fixed pipe and a fixed ring block are fixedly connected to the inner cavity of the extraction box. A storage pipe is fixedly connected to one end of the fixed pipe.

A moving rod is connected to the inner cavity of one side of the moving block. A rotating ring block is slidably connected to the surface of the moving rod. A second driving mechanism is provided on one side of the rotating ring block. A PLC controller is fixedly connected to the top of the mixing box.

[0007] Preferably, the second drive mechanism includes a second servo motor, one side of which is fixedly connected to the top of the extraction box. The output end of the second servo motor passes through the extraction box and is fixedly connected to a worm gear. A connecting hollow block is fixedly connected to one side of the rotating ring block, and a worm wheel is fixedly connected to the surface of the connecting hollow block. The teeth of the worm gear mesh with the teeth of the worm wheel.

[0008] Preferably, the mixing mechanism includes an internal toothed block, the bottom of which is slidably connected to the mixing chamber, and an incomplete gear rotatably connected to the top of the mixing chamber. The teeth of the incomplete gear mesh with the teeth of the internal toothed block. A connecting block is fixedly connected to the bottom of the internal toothed block, a stirring block is fixedly connected to the bottom of the connecting block, and a connecting plate is fixedly connected to the bottom of the stirring block. A first drive assembly is provided on the top of the rotary printing machine body.

[0009] Preferably, the first drive assembly includes a connecting frame, the bottom of which is fixedly connected to the top of the mixing chamber, and a first servo motor is fixedly connected to the top of the connecting frame. The output end of the first servo motor passes through the connecting frame and is fixedly connected to the top of the incomplete gear.

[0010] Preferably, the inner cavity of the mixing box is fixedly connected to a limiting rod, and the inner cavity of the connecting block is slidably connected to the surface of the limiting rod.

[0011] Preferably, a limiting rod is fixedly connected to one end of the worm gear, and one end of the limiting rod is rotatably connected to the inner cavity of the storage tube.

[0012] The advantages of this utility model are:

[0013] This invention utilizes a second servo motor to drive a rotating ring block, which in turn moves a movable block, thus adjusting the ink output. This results in varying amounts of ink being drawn from multiple extraction boxes, allowing for the mixing and adjustment of the final ink color through the different amounts of various colors. Simultaneously, a PLC controller synchronizes the operation of multiple second extraction pumps and worm gears. This effectively reduces deviations between the final mixed color and the desired color caused by factors such as extraction time and force when the operator uses the extraction pumps. It solves the problem of color discrepancies between the final mixed color and the desired color due to factors like extraction time and force, which can affect the final printed product's color effect.

Detailed Implementation

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses an automatic color-matching rotary printing machine. (Refer to...) Figure 1 and Figure 6 An automatic color-adjusting rotary printing machine includes a rotary printing machine body 1. A printing roller 2 and a feed roller 3 are rotatably connected to one side of the rotary printing machine body 1. An ink inlet pipe 4 is provided at one end of the printing roller 2. A first extraction pump 5 and a mixing box 6 are fixedly connected to the surface of the ink inlet pipe 4. A connecting pipe 7 is fixedly connected to the inner cavity of the mixing box 6. Multiple connecting pipes 7 are provided. A second extraction pump 10 is fixedly connected to the surface of each of the multiple connecting pipes 7. An adjustment mechanism 9 is provided at one end of each of the multiple connecting pipes 7. A mixing mechanism 8 is provided in the inner cavity of the mixing box 6. The multiple adjustment mechanisms 9 have the same structure.

[0027] The rotary printing press body 1 can connect the printing roller 2 and the feed roller 3. The printing roller 2 can connect to the ink inlet pipe 4. The connection between the ink inlet pipe 4 and the first extraction pump 5 and the mixing tank 6 allows the first extraction pump 5 to pump the ink inside the mixing tank 6 into the printing roller 2 when it is in operation, so that the object can be printed by the printing roller 2. At the same time, the rotary printing press body 1, the printing roller 2, the feed roller 3 and the ink inlet pipe 4 are all existing technologies in the field, so the specific working principle will not be elaborated here. The setting of the second extraction pump 10 allows the ink inside the adjusting mechanism 9 to be smoothly adjusted when it enters the mixing tank 6 through the connecting pipe 7. At the same time, the structures of the multiple adjusting mechanisms 9 are the same, so the working principle is also the same, and will not be elaborated here.

[0028] Reference Figure 5 and Figure 6 The adjusting mechanism 9 includes a dispensing box 901. The inner cavity of the dispensing box 901 is fixedly connected to the surface of the connecting pipe 7. A fixed pipe 902 and a fixed ring block 904 are fixedly connected to the inner cavity of the dispensing box 901. A storage pipe 903 is fixedly connected to one end of the fixed pipe 902. A slider 905 is slidably connected to the inner cavity of the fixed ring block 904. A moving block 906 is fixedly connected to one end of the slider 905. A moving rod 907 is connected to the inner cavity of one side of the moving block 906. A rotating ring block 908 is slidably connected to the surface of the moving rod 907. A second driving mechanism 909 is provided on one side of the rotating ring block 908. A PLC controller 910 is fixedly connected to the top of the mixing box 6. The extraction box 901 can be connected to the storage tube 903 through the fixed tube 902. The storage tube 903 can store different inks, and the inks stored in multiple storage tubes 903 are of different colors. The fixed ring block 904 can be connected to the moving block 906 through the slider 905. At the same time, the moving rod 907 connected inside the moving block 906 can be smoothly connected to the rotating ring block 908. When in use, the second drive mechanism 909 can smoothly drive the rotating ring block 908 to rotate.

[0029] Furthermore, the rotation of the rotating ring block 908 can smoothly drive the moving block 906 to move via the moving rod 907. Since the slider 905 slides inside the fixed ring block 904, the moving block 906 can smoothly move along the inside of the fixed ring block 904. When the fixed ring block 904 moves, it can gradually close or open the connection between the fixed tube 902 and the extraction box 901, thereby controlling the amount of ink extracted. When multiple second extraction pumps 10 operate synchronously, they will extract ink from multiple storage tubes 903 with the same pumping force and the same pumping time. Since the positions of the multiple moving blocks 906 are different, the amount of ink extracted from multiple storage tubes 903 is different. By utilizing the different extraction amounts of various inks, color adjustment can be achieved.

[0030] Reference Figure 6 and Figure 7 The second drive mechanism 909 includes a second servo motor 9094. One side of the second servo motor 9094 is fixedly connected to the top of the extraction box 901. The output end of the second servo motor 9094 passes through the extraction box 901 and is fixedly connected to a worm gear 9091. A connecting hollow block 9092 is fixedly connected to one side of the rotating ring block 908. A worm wheel 9093 is fixedly connected to the surface of the connecting hollow block 9092. The teeth of the worm gear 9091 and the teeth of the worm wheel 9093 mesh with each other. The second servo motor 9094 can smoothly drive the worm gear 9091 to rotate during operation. By utilizing the meshing between the worm gear 9091 and the worm wheel 9093, the worm wheel 9093 and the connecting hollow block 9092 are driven to rotate. The rotation of the connecting hollow block 9092 can smoothly drive the rotating ring block 908 to rotate, thereby realizing the position adjustment of the moving block 906.

[0031] Reference Figure 3 and Figure 8 The mixing mechanism 8 includes an internal gear block 801, the bottom of which is slidably connected to the mixing box 6. An incomplete gear 802 is rotatably connected to the top of the mixing box 6. The teeth of the incomplete gear 802 mesh with the teeth of the internal gear block 801. A connecting block 803 is fixedly connected to the bottom of the internal gear block 801. A stirring block 805 is fixedly connected to the bottom of the connecting block 803. A connecting plate 804 is fixedly connected to the bottom of the stirring block 805. A first drive assembly 806 is provided on the top of the rotary printing press body 1. When the incomplete gear 802 rotates, it can smoothly drive the internal gear block 801 to reciprocate by meshing with itself. This drives the stirring block 805 and the connecting plate 804 to reciprocate together through the connecting block 803. When the connecting plate 804 reciprocates inside the mixing box 6, it can smoothly stir and mix the ink inside the mixing box 6, thereby achieving the mixing and adjustment of ink color.

[0032] Reference Figure 8The first drive assembly 806 includes a connecting frame 8061. The bottom of the connecting frame 8061 is fixedly connected to the top of the mixing box 6. A first servo motor 8062 is fixedly connected to the top of the connecting frame 8061. The output end of the first servo motor 8062 passes through the connecting frame 8061 and is fixedly connected to the top of the incomplete gear 802. The connecting frame 8061 can connect and install the first servo motor 8062. When the first servo motor 8062 is operating, it can smoothly drive the incomplete gear 802 to rotate, thereby realizing the reciprocating movement of the connecting plate 804. At the same time, the PLC controller 910 is electrically connected to the second servo motor 9094, the first servo motor 8062, the second extraction pump 10, and the first extraction pump 5, so that the PLC controller 910 can control the operation of the second servo motor 9094, the first servo motor 8062, the second extraction pump 10, and the first extraction pump 5.

[0033] Reference Figure 8 The inner cavity of the mixing box 6 is fixedly connected to the limiting rod 11, and the inner cavity of the connecting block 803 is slidably connected to the surface of the limiting rod 11. The limiting rod 11 can limit the movement of the connecting block 803, so that when the connecting block 803 drives the connecting plate 804 to move inside the mixing box 6, it can move stably enough.

[0034] Reference Figure 6 and Figure 7 One end of the worm gear 9091 is fixedly connected to a limiting rod 12. One end of the limiting rod 12 is rotatably connected to the inner cavity of the storage tube 903. The limiting rod 12 can limit and strengthen the rotation of the worm gear 9091, making it stable enough during rotation and preventing swaying or shaking.

[0035] Working Principle: When using this device, the operator can adjust the ink color as needed. During color adjustment, the operator can start the second servo motor 9094 via the PLC controller 910. When operating, the second servo motor 9094 smoothly drives the connecting hollow block 9092 and the rotating ring block 908 to rotate through the meshing between the worm gear 9091 and the worm wheel 9093. During rotation, the rotating ring block 908 can push the moving block 906 through the connection between the moving rod 907 and itself, and the connection between the moving rod 907 and the moving block 906, allowing the moving block 906 to smoothly follow the sliding... Block 905 moves on one side of the fixed ring block 904. When moving, the moving block 906 will expand or close the center of the fixed ring block 904. When closed, it will block the ink from the inside of the storage tube 903, reducing the amount of ink entering the connecting tube 7 through the extraction box 901. When the moving block 906 expands, it can smoothly increase the amount of ink entering the extraction box 901. Since there are multiple adjusting mechanisms 9, and the operating time of the multiple second servo motors 9094 is different through the PLC controller 910, the positions of the multiple moving blocks 906 are also different. Then the operation of the second servo motors 9094 stops.

[0036] The ink inside the extraction box 901 and the storage tube 903 is extracted by the operation of the second extraction pump 10. At the same time, the operating time and extraction force of multiple second extraction pumps 10 are the same. Since the positions of multiple moving blocks 906 are different, the amount of ink extracted from each extraction box 901 is different. Therefore, after the ink is extracted into the mixing box 6, it can be effectively mixed and adjusted to produce different colors of ink by the different amounts of each color of ink. At the same time, the operation of the first servo motor 8062 can also drive the incomplete gear 802 to rotate, and then use the internal gear block 801 to drive the connecting plate 804 to move back and forth, so as to stir the ink of multiple colors and achieve the mixing of ink. Finally, the mixed and adjusted ink is extracted into the printing roller 2 by the operation of the first extraction pump 5, so as to achieve the printing of objects.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
