Description

Technical Field

[0001] This utility model relates to the field of printing press structure technology, specifically to a printing press ink fountain structure. Background Technology

[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, plastics, leather, PVC, and PC to reproduce the content of the original manuscript in batches.

[0003] Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). The working principle is as follows: First, the text and images to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the areas with text and images on the printing plate by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics) to reproduce printed products identical to the printing plate.

[0004] The printing press has a complex internal structure and requires the use of a printing ink fountain during printing. The traditional printing ink fountain structure is inconvenient to adjust the amount of ink dispensed. Therefore, the amount of ink dispensed in a traditional ink fountain structure is fixed at the same time and cannot be adjusted. In actual use, it cannot be adapted to different ink volume printing requirements and has certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide a printing press ink fountain structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printing press ink fountain structure, including an ink cartridge, a lower ink plate fixed to the bottom surface of the ink cartridge, a plurality of ink holes being provided on the lower ink plate, the plurality of ink holes being linearly distributed at equal intervals, the interior of the lower ink plate being hollow, two sets of slots being provided on one side of the lower ink plate, an adjusting plate being movably inserted into each of the two sets of slots, a sealing rubber gasket being fixedly installed on the upper surface of each of the two adjusting plates, a push plate being fixedly installed on the outer wall of one side of the adjusting plate, lower support plates being fixedly installed at both ends of the lower surface of the lower ink plate, an upper vertical plate being fixedly installed at the middle position of the upper surface of each of the two lower support plates, and two sets of symmetrically distributed drive cylinders being fixedly installed on the outer wall of each upper vertical plate.

[0007] Preferably, the lower support plate and the corresponding upper vertical plate are arranged perpendicularly to each other.

[0008] Preferably, the output end of the drive cylinder is movably connected to a pneumatic rod, and the top ends of both pneumatic rods are fixedly connected to the side wall of the push plate.

[0009] Preferably, a guide rod is fixedly installed at the middle position of the outer surface of the push plate.

[0010] Preferably, the top end of the guide rod passes through the upper vertical plate, and the guide rod and the upper vertical plate are in sliding contact.

[0011] Preferably, an anti-detachment sleeve is fixedly installed at the top end of the guide rod, and the diameter of the anti-detachment sleeve is larger than the diameter of the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features adjustable plates that are movably inserted into the left and right sides of the ink-removing plate. In actual use, these adjustable plates can move under the action of a drive cylinder and a drive rod, allowing them to extend and retract within the lower template. By adjusting the extension and retraction of the plates, the diameter of the ink-removing hole can be changed. The extension and retraction of the plates can effectively open and close the ink-removing hole. By opening the hole laterally and closing it, the ink discharge process can be automatically controlled, providing a practical effect of automated ink control and making it more convenient to use.

[0014] Simultaneously, by controlling the insertion depth of the adjusting plate, the diameter of the ink outlet can be freely adjusted. By changing the opening degree of the ink outlet, it achieves the practical effect of valve control. When the opening degree of the ink outlet is small, the amount of ink discharged within a specified time is reduced. When the ink outlet is fully open, the amount of ink discharged reaches the maximum threshold. By adjusting the extension and retraction of the adjusting plate, the opening degree of the ink outlet can be effectively controlled, thus achieving the practical effect of dynamic adjustment of ink discharge. The amount of ink discharged can be dynamically adjusted according to different printing and usage requirements, making it suitable for different printing ink discharge requirements and effectively reducing usage limitations.

[0015] Furthermore, this utility model features an adjustment structure with adjustment plates on both the left and right sides of the ink cartridge, allowing for independent adjustment of each zone during use. This enables the left and right sides of the ink cartridge to be opened or closed simultaneously, or to be opened or closed on one side only, making the structure more versatile. Additionally, by controlling the insertion depth of the two adjustment plates, the ink output of the left and right zones can be differentiated, resulting in a higher ink output on the left and a lower ink output on the right, and vice versa. This caters to different ink output needs under various circumstances, enhancing practicality and offering more diverse implementation methods. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4An embodiment of this utility model is provided: a printing press ink fountain structure, including an ink cartridge 1. The ink cartridge 1 can be used to store printing ink during use. A lower ink plate 2 is fixed on the bottom surface of the ink cartridge 1. The lower ink plate 2 has a plurality of ink holes 3, which are linearly distributed at equal intervals.

[0025] With this structural design, the ink stored inside the ink cartridge 1 can be discharged through the ink outlet 3 of the ink outlet plate 2, thereby completing the normal ink dispensing operation of the ink fountain structure of this utility model.

[0026] The lower ink plate 2 is hollow inside. Two sets of slots 4 are provided on one side of the lower ink plate 2. Adjustment plates 5 are movably inserted into both sets of slots 4. Sealing rubber gaskets are fixedly installed on the upper surface of the two adjustment plates 5. The sealing rubber gaskets can improve the contact sealing effect between the adjustment plates 5 and the lower die hole 3, and prevent ink from leaking out from the gap between the adjustment plates 5 and the lower ink hole 3. It has a good sealing contact effect. A push plate 6 is fixedly installed on the outer wall of one side of the adjustment plate 5.

[0027] Furthermore, in order to drive the adjustment plate 5, lower support plates 12 are fixedly installed at both ends of the lower surface of the ink plate 2, and upper vertical plates 7 are fixedly installed at the middle position of the upper surface of the two lower support plates 12. The lower support plates 12 and the corresponding upper vertical plates 7 are set perpendicular to each other.

[0028] Two sets of symmetrically distributed drive cylinders 8 are fixedly installed on the outer wall of each upper vertical plate 7. The output end of the drive cylinder 8 is movably connected to a pneumatic rod 9, and the top ends of the two pneumatic rods 9 are fixedly connected to the side wall of the push plate 6.

[0029] This invention features adjustable plates 5 movably inserted into the left and right sides of the ink lower plate 2. In actual use, these adjustable plates 5 can move under the action of the drive cylinder 8 and drive rod 9, allowing them to extend and retract within the lower plate 2. Adjusting the extension and retraction of the plates 5 changes the diameter of the ink lower hole 3. This adjustment effectively opens and closes the ink lower hole 3, and the ink discharge process can be automatically controlled by opening and closing the hole. This provides a practical effect of automated ink control, making it more convenient to use.

[0030] In this embodiment, in order to provide a certain displacement guidance for the extension and retraction of the pneumatic rod 9, a guide rod 10 is fixedly installed at the middle position of the outer surface of the push plate 6. The top end of the guide rod 10 passes through the upper vertical plate 7, and the guide rod 10 and the upper vertical plate 7 are in sliding contact.

[0031] By using the structure between the guide rod 10 and the upper vertical plate 7, a certain displacement guidance can be provided for the extension and retraction of the moving rod 9, so that it can maintain a linear extension and retraction effect.

[0032] In this embodiment, in order to prevent the end of the guide rod 10 from detaching, an anti-detachment sleeve 11 is fixedly installed on the top end of the guide rod 10, and the diameter of the anti-detachment sleeve 11 is larger than the diameter of the guide rod 10.

[0033] Working principle: When in use, the ink fountain structure of this utility model can be installed on a suitable printing machine structure through the lower support plate 12;

[0034] In actual use, the ink stored inside the ink cartridge 1 can be discharged through the ink outlet 3 of the ink outlet plate 2, thereby completing the normal ink dispensing operation of the ink fountain structure of this utility model.

[0035] The present invention uses a drive cylinder 8 to drive a pneumatic rod 9 to extend and retract. When the pneumatic rod 9 extends, it can use the push plate 6 at the top to insert the adjusting plate 5 into the ink plate 2. When the adjusting plate 5 is fully inserted, it can block and seal the ink hole 3, thereby stopping the ink fountain structure of the present invention from dispensing ink.

[0036] When the driving cylinder 8 drives the air rod 9 to retract, the adjusting plate 5 moves to the outside of the lower ink plate 2 under the action of the driving cylinder 8 and the air rod 9. During the process of the adjusting plate 5 moving to the outside of the lower ink plate 2, the ink outlet 3 gradually opens, and the ink stored in the ink cartridge 1 can be discharged through the gradually opening ink outlet 3, thus completing the normal ink output work.

[0037] When the adjusting plate 5 is completely removed from the ink outlet 3, the ink outlet 3 is no longer blocked by the adjusting plate 5, and the amount of ink flowing out in this state reaches the maximum threshold.

[0038] Based on the above structure, this utility model features adjustable insert plates 5 movably inserted into the left and right sides of the ink lower plate 2. In actual use, the adjustable insert plates 5 can move under the action of the drive cylinder 8 and the drive rod 9, thereby allowing the adjustable insert plates 5 to extend and retract within the lower plate 2. By adjusting the extension and retraction of the insert plates 5, the diameter of the ink lower hole 3 can be changed. The extension and retraction of the insert plates 5 can effectively open and close the hole of the ink lower hole 3. By opening the hole by pulling it to the side and closing it by extending it, the ink discharge process can be automatically controlled, achieving the practical effect of automatically controlling the ink switch, making it more convenient to use.

[0039] Meanwhile, by controlling the insertion depth of the adjusting plate 5, the diameter of the ink outlet 3 can be freely adjusted. By changing the opening degree of the ink outlet 3, it achieves the practical effect of valve control. When the opening degree of the ink outlet 3 is small, the amount of ink discharged within a specified time is reduced. When the ink outlet 3 is fully open, the amount of ink discharged reaches the maximum threshold. By adjusting the extension and retraction of the adjusting plate 5, the opening degree of the ink outlet 3 can be effectively controlled, thus achieving the practical effect of dynamic adjustment of ink discharge. The amount of ink discharged can be dynamically adjusted according to different printing and usage requirements, and it is applicable to different printing ink discharge requirements, effectively reducing usage limitations.

[0040] Furthermore, this utility model features an adjustment structure with adjustment plates 5 on both the left and right sides of the ink cartridge 1. This allows for independent adjustment of the ink output in different zones, enabling both sides of the ink cartridge 1 to be opened or closed simultaneously, or to be opened or closed on only one side. This makes the structure more versatile. By controlling the insertion depth of the two adjustment plates 5, the ink output of the two zones can be differentiated, resulting in a larger ink output on the left and a smaller ink output on the right, and vice versa. This satisfies the ink output needs under different circumstances, making it more practical and allowing for more diverse implementation methods.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
