Description

Technical Field

[0001] This utility model relates to the field of ink detection technology, and in particular to a printing press ink monitoring device. Background Technology

[0002] In the printing production process, precise control of various ink parameters is necessary to ensure consistent print quality. Ink quantity and concentration are two key parameters. Insufficient ink quantity can lead to printing interruptions and affect production efficiency; while inappropriate ink concentration, whether too high or too low, will affect the clarity of the printed image, color reproduction, and ink drying speed, thereby reducing the quality of the printed product.

[0003] In traditional ink monitoring methods for printing presses, the ink level is typically monitored manually by periodically checking the ink level in the ink tank. Operators need to open the ink tank lid or roughly judge the ink level by observing simple scale lines on the side of the ink tank.

[0004] Traditional methods lack effective means for monitoring ink concentration. Generally, operators rely primarily on experience to judge whether the ink concentration is appropriate. For example, they might roughly estimate the ink concentration by observing surface phenomena such as color depth and drying speed on printed samples. However, this experience-based judgment method is highly subjective and uncertain. Different operators have different experience and judgment standards, and even the same operator may make different judgments at different times and under different conditions. Utility Model Content

[0005] The purpose of this invention is to provide a printing press ink monitoring device that solves the problems of low efficiency and inaccuracy in the traditional method of manually monitoring ink quantity and concentration.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A printing press ink monitoring device includes a bracket, an ink tank for storing ink is provided inside the bracket, a transparent long tube is fixedly connected to one side of the ink tank, and a transparent short tube is fixedly connected to the other side of the ink tank. Both ends of the transparent long tube and both ends of the transparent short tube are connected to the ink tank. A floating ball is provided inside the transparent short tube. A dilution tank for holding diluent is provided at the top of the bracket, and a drain pipe is provided at the bottom of the dilution tank, with the drain pipe facing the ink tank.

[0007] Preferably, the support includes a base plate, columns, and a top plate. The base plate is horizontally positioned, and the top plate is located above the base plate. The four corners of the top plate are connected to the base plate by a column. The ink cartridge is positioned between the top plate and the base plate. The bottom end of the column is fixedly connected to the base plate, and the top end of the column is slidably inserted into the interior of the corresponding corner of the top plate. A support block is fixedly connected to the outside of the column, and the support block is located at the bottom of the top plate.

[0008] Preferably, a handle is symmetrically fixedly connected to the top of the top plate, providing a stable point of leverage for the operator.

[0009] Preferably, a drain pipe is connected to one side of the bottom of the ink cartridge, and a flexible hose is provided on one side of the ink cartridge. The end of the flexible hose is bent and inserted into the inside of the ink cartridge. The drain pipe provides a controllable liquid discharge channel for the ink cartridge, and external ink is introduced into the ink cartridge through the flexible hose.

[0010] Preferably, a solenoid valve is provided at the connection between the drain pipe and the discharge pipe, and the opening and closing of the drain pipe and the discharge pipe are controlled by the solenoid valve.

[0011] Preferably, the top of the dilution tank is provided with a lid for sealing and opening to add diluent. Under normal conditions, the lid is closed on the top of the dilution tank to prevent external dust, impurities, etc. from entering the dilution tank.

[0012] Preferably, the top of the column is set in an arc shape. The arc shape can play a guiding role, making the column easier to insert into the top plate.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model provides a simple and practical method for monitoring ink concentration through the combination of a transparent short tube and a floating ball. When the ink concentration in the ink tank changes, the ink density changes accordingly. The relationship between the buoyancy force on the floating ball and its own weight in the transparent short tube also changes accordingly, causing the floating ball to float up and down in the transparent short tube. By observing the position of the floating ball, the operator can roughly judge the ink concentration in the ink tank. Although more precise instruments are still needed for detailed detection of ink concentration, this preliminary concentration monitoring method can promptly remind the operator of changes in ink concentration, providing a reference for subsequent concentration adjustments and helping to maintain the stability of ink concentration during the printing process.

[0015] 2. This utility model connects the ink tank to a transparent tube, ensuring that the ink level inside the tube remains consistent with that inside the tank. Operators can quickly and accurately assess the ink level by simply observing the ink level inside the tube. This intuitive monitoring method eliminates the need for complex instruments, improving the efficiency and accuracy of ink level monitoring. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 This embodiment provides a printing press ink monitoring device, including a bracket 1. The bracket 1 has an ink tank 2 for storing ink inside. A transparent long tube 3 is fixedly connected to one side of the ink tank 2, and a transparent short tube 4 is fixedly connected to the other side of the ink tank 2. Both ends of the transparent long tube 3 and both ends of the transparent short tube 4 are connected to the ink tank 2. A floating ball 5 is provided inside the transparent short tube 4. A dilution tank 6 for holding diluent is provided at the top of the bracket 1. A drain pipe 7 is provided at the bottom of the dilution tank 6 and is positioned directly opposite the ink tank 2.

[0023] This device connects ink tank 2 to the ink reservoir of a printing press, allowing ink from the printing press to be introduced into ink tank 2. A transparent long tube 3 connects to ink tank 2. Based on the principle of communicating vessels, the ink level in the transparent long tube 3 is consistent with the ink level in ink tank 2. Therefore, the amount of ink in ink tank 2 can be determined by observing the ink level in the transparent long tube 3. A transparent short tube 4, in conjunction with a floating ball 5, causes the ink density to change as the ink concentration in ink tank 2 changes. The buoyancy of the floating ball 5 within the transparent short tube 4 changes in relation to its own weight, causing it to float up and down within the transparent short tube 4. The position of the floating ball 5 can be used to roughly determine the ink concentration in ink tank 2. For detailed ink concentration testing, more precise instruments are required. Due to ink evaporation and other factors, the ink concentration may increase after prolonged use. In this case, a thinner can be added to the dilution tank 6, which is then added to ink tank 2 via the drain pipe 7 to reduce the ink concentration in ink tank 2.

[0024] The bracket 1 includes a base plate 11, a column 12, and a top plate 13. The base plate 11 is horizontally positioned, and the top plate 13 is located above the base plate 11. The four corners of the top plate 13 are connected to the base plate 11 by a column 12. The ink cartridge 2 is positioned between the top plate 13 and the base plate 11. The bottom end of the column 12 is fixedly connected to the base plate 11, and the top end of the column 12 is slidably inserted into the interior of the corresponding corner of the top plate 13. A support block 14 is fixedly connected to the outside of the column 12, and the support block 14 is located at the bottom of the top plate 13.

[0025] When installing the top plate 13, move the corresponding corner of the top plate 13 downward along the axial direction of the column 12, so that the top of the column 12 is inserted into the interior of the corresponding corner of the top plate 13 until the bottom of the top plate 13 contacts the upper surface of the support block 14. The support block 14 generates an upward supporting force on the top plate 13, so that the top plate 13 is stably installed on the column 12. At this time, the ink box 2 is firmly placed between the top plate 13 and the bottom plate 11. When it is necessary to adjust, remove or put away the ink box 2, simply apply an external force upward to lift the top plate 13 upward along the axial direction of the column 12, so that the top of the column 12 slides out from the corresponding corner of the top plate 13, and the top plate 13 can be easily removed, thus providing sufficient space for the operation of the ink box 2. After the operation is completed, reinstall the top plate 13 back to its original position according to the above installation method. This plug-in connection method has a simple structure and is easy to operate, which improves the efficiency of maintaining and operating the ink box 2.

[0026] The top of the top plate 13 is symmetrically fixed with a handle 15. When installing the top plate 13, the handle 15 can be used to control the movement direction of the top plate 13 more precisely, so that the corresponding corner of the top plate 13 can move smoothly downward along the axial direction of the column 12 and insert into the top of the column 12. When removing the top plate 13, the upward pulling force applied by the handle 15 can lift the top plate 13 from the column 12 more easily and smoothly, avoiding the slippage and unstable force that may occur when directly grabbing the top plate 13 by hand, thus improving the convenience and safety of operation.

[0027] A drain pipe 21 is connected to one side of the bottom of the ink tank 2, and a flexible hose 22 is provided on one side of the ink tank 2. The tip of the flexible hose 22 is bent and inserted into the ink tank 2. The drain pipe 21 provides a controllable liquid discharge channel for the ink tank 2. When it is necessary to clean the ink tank 2, replace the ink, or drain the excess liquid in the ink tank 2 after the ink evaporates and concentrates, the valve on the bottom drain pipe 21 can be opened to allow the liquid in the ink tank 2 to flow out under the action of gravity, thus realizing the liquid discharge operation in the ink tank 2. The bent tip of the flexible hose 22 inserted into the ink tank 2 has two advantages. First, it can easily introduce external ink into the ink tank 2 through the flexible hose 22. When adding ink to the ink tank 2, simply connect the flexible hose 22 to the ink supply source, and the ink can flow into the ink tank 2 through the flexible hose 22. Second, the bent tip can reduce the splashing of ink when it flows into the ink tank 2, avoiding ink splashing out of the ink tank 2 and causing waste and pollution to the surrounding environment. It also makes it easy to observe and monitor the liquid level of the ink in the ink tank 2, ensuring the normal operation of the ink monitoring device of the printing press.

[0028] Solenoid valves 8 are installed at the connection points of drain pipe 7 and discharge pipe 21. When it is necessary to add thinner to ink tank 2 to reduce ink concentration, the control circuit energizes the solenoid valve 8 on drain pipe 7. The valve core of solenoid valve 8 moves under the action of electromagnetic force, opening the channel of drain pipe 7. The thinner in dilution tank 6 can then flow into ink tank 2 through drain pipe 7. Similarly, when it is necessary to open the discharge pipe 21 at the bottom of ink tank 2, the solenoid valve 8 at the corresponding position can be opened.

[0029] The top of the dilution tank 6 is equipped with a lid 61 for sealing and opening to add diluent. The lid 61 fits tightly with the top of the dilution tank 6 to provide a seal. Under normal conditions, the lid 61 is closed on the top of the dilution tank 6 to prevent external dust, impurities, etc. from entering the dilution tank 6, thus avoiding contamination of the diluent and ensuring the purity of the diluent. This ensures that when diluent is added to the ink cartridge 2 later, the quality of the ink and the printing effect will not be affected by the impurity of the diluent.

[0030] The top of the column 12 is arc-shaped. When installing the top plate 13, since the corresponding corner of the top plate 13 needs to be inserted into the top of the column 12 along the axis of the column 12, the arc-shaped design can play a guiding role, making the insertion of the top plate 13 smoother. This reduces the occurrence of insertion difficulties, jamming, or even damage to the top plate 13 or the column 12 caused by the sharp or uneven top of the column 12, thus improving the efficiency and success rate of installation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
