Description

Technical Field

[0001] This utility model relates to the field of water-based ink dilution technology, specifically to a water-based ink dilution device. Background Technology

[0002] Water-based inks use water as the main solvent, are environmentally friendly and non-toxic, and are widely used in paper and cardboard printing. However, due to their high viscosity, direct printing can lead to poor flowability and uneven transfer. Therefore, they need to be adjusted with water or a special thinner to reduce viscosity, improve printability, and ensure uniform color and a smooth printing process.

[0003] In the existing technology, traditional water-based ink dilution equipment usually uses simple stirring blades for unidirectional stirring during the mixing process, which can easily lead to uneven mixing of ink and diluent, resulting in localized excessively high concentrations or precipitation, affecting the dilution effect and product quality.

[0004] At the same time, the equipment is difficult to clean after use. The mixing structure is complex and there are many blind spots for cleaning. Residual ink is easy to dry and accumulate, which not only affects the subsequent use effect, but may also cause cross-contamination.

[0005] In addition, the addition of ink and diluent relies heavily on manual control, making it difficult to guarantee the accuracy of the mixing ratio. Furthermore, the lack of an effective cleaning mechanism in the piping system further reduces the practicality and reliability of the equipment.

[0006] Therefore, there is an urgent need for a water-based ink dilution device that is highly efficient in mixing, easy to clean, and has precise dosing control. Utility Model Content

[0007] The purpose of this invention is to provide a water-based ink dilution device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a water-based ink dilution device, including a dilution tank, a tank cover at the top of the dilution tank, a stirring shaft mounted on the tank cover via a bearing, and a drive assembly configured in conjunction with the stirring shaft, multiple stirring rods arranged longitudinally on the stirring shaft, a scraper at the tail end of each stirring rod, an axial flow impeller at the bottom of the stirring shaft, a spoked impeller at the upper end of the stirring shaft, double helical blades mounted on the stirring rods between the axial flow impeller and the spoked impeller, a conveying chamber opening downwards at the top of the stirring shaft, a cleaning liquid supply pipe mounted at the top of the conveying chamber via a sealed bearing, a cleaning liquid supply pipe connected to an external cleaning liquid source, and a spray cleaning structure configured between the conveying chamber and the scraper.

[0009] The present invention is further configured such that the spray cleaning structure includes a spray chamber, which is opened inside the scraper. A connecting chamber is opened inside the stirring rod. The two ends of the connecting chamber are connected to the conveying chamber and the spray chamber. Spray nozzles are provided on the top, inner side and outer side of the spray chamber. When it is necessary to clean the inside of the dilution tank, the cleaning liquid is conveyed to the conveying chamber through the cleaning liquid supply pipe and enters the spray chamber through the connecting chamber. It is then sprayed out through the spray nozzles on the spray chamber. The present invention sets the spray nozzles on the top, inner side and outer side of the spray chamber. In this way, the spray nozzles on the outer side and the top can fully rinse the inner wall and the top wall of the dilution tank, and the spray nozzles on the inner side can rinse the double helical blades inside the dilution tank, thereby achieving a comprehensive cleaning of the inside of the dilution tank and reducing cleaning dead corners.

[0010] The present invention is further configured such that the barrel lid is provided with an ink inlet pipe and a diluent inlet pipe, and both the ink inlet pipe and the diluent inlet pipe are provided with inlet control components. The invention adopts a dual independent conveying channel to avoid premature contact between the two materials, which would lead to uneven dilution in some areas. The inner wall of the pipe is provided with an anti-stick coating to reduce residue.

[0011] The present invention is further configured such that the liquid inlet control component includes a metering pump and a flow meter, which are respectively installed on the ink inlet pipe and the diluent inlet pipe, and the cooperation of the metering pump and the flow meter provides real-time feedback on the delivery amount of ink and diluent.

[0012] The present invention is further configured such that an ink connecting pipe is provided on the ink inlet pipe, and an ink supply pipe is installed on the ink connecting pipe through a pipe joint. The input end of the ink supply pipe is connected to an external ink source, which facilitates the disassembly and replacement of the ink supply pipe.

[0013] The present invention is further configured such that a diluent connecting pipe is provided on the diluent inlet pipe, and a diluent supply pipe is installed on the diluent connecting pipe through a pipe joint. The input end of the diluent supply pipe is connected to a diluent source, which facilitates the disassembly and replacement of the diluent supply pipe.

[0014] This utility model is further configured to include a cleaning two-way pipe, the output end of which is connected to the tail ends of the ink inlet pipe and the diluent inlet pipe, respectively. The input end of the cleaning two-way pipe is connected to a cleaning liquid delivery pipe, which is externally connected to a cleaning liquid source. The cleaning liquid is delivered to the cleaning two-way pipe through the cleaning liquid delivery pipe, and then to the ink inlet pipe and the diluent inlet pipe through the cleaning two-way pipe. In this way, the ink inlet pipe and the diluent inlet pipe can be cleaned after use to avoid residue inside the pipes. Here, a valve can be installed at one end of the ink inlet pipe and the diluent inlet pipe connected to the cleaning two-way pipe to control the opening and closing, so as to prevent the ink and diluent from contacting and mixing with the cleaning liquid.

[0015] This utility model is further configured such that the driving component includes a drive motor, and a synchronous belt drive structure is provided between the output end of the drive motor and the stirring shaft. Here, the synchronous belt drive structure achieves drive through the meshing of the synchronous pulley and the synchronous belt. The synchronous belt drive has the characteristics of constant transmission ratio and stable transmission during the process, which is widely used in multi-axis synchronous drive. Those skilled in the art should know this, and this utility model will not elaborate on it. In use, the drive motor is started, and the rotation of the stirring shaft can be driven by the cooperation of the drive motor and the synchronous belt drive structure, thereby realizing the rotation drive of the stirring rod, spoke impeller, double helical blade, axial flow impeller, etc.; the spoke blade The impeller includes an inner mounting ring and a stabilizing outer ring. The inner mounting ring is mounted on the stirring shaft. Multiple radial guide vanes are evenly arranged between the inner mounting ring and the stabilizing outer ring. During the stirring process, the ink can achieve overall flow guidance through the radial guide vanes and the axial flow impeller. The ink will pass evenly through the gaps between the radial guide vanes, thus improving the uniformity of the ink during the circulating stirring process. The axial flow impeller includes a mounting disc, which is mounted on the stirring shaft. Multiple axial flow vanes are evenly mounted on the mounting disc. The axial flow vanes continuously drive the ink to descend and then flip outward and upward, thereby achieving cyclic drive.

[0016] Compared with existing technologies, the beneficial effects of this invention are: 1. High-efficiency mixing and anti-sedimentation design: This invention guides the liquid to form an up-and-down circulating flow through the synergistic action of the spoked impeller and the axial flow impeller. The axial flow blades continuously push the ink downwards and then flip it outwards and upwards, effectively preventing sedimentation at the bottom. At the same time, the double helix blades achieve convection and stirring, which, together with the stirring rod, breaks up clumps, significantly improving stirring efficiency and dilution uniformity, ensuring that the ink and diluent are fully mixed, shortening the dilution time and improving the quality of the finished product.

[0017] 2. All-round self-cleaning system: The device has a built-in spray cleaning structure. The cleaning solution is delivered through the conveying chamber and connecting chamber to the spray chamber inside the scraper, and is simultaneously sprayed out by multi-directional nozzles on the top, inside and outside, achieving a comprehensive rinsing of the inner wall and top wall of the dilution tank and the double helical blades, greatly reducing cleaning dead spots. This design effectively solves the problems of incomplete cleaning and residue accumulation in traditional dilution devices, ensuring the hygiene of the equipment and the purity for subsequent use.

[0018] 3. Modular Piping and Intelligent Control: The system employs dual independent delivery pipelines for ink and diluent, equipped with metering pumps and flow meters to monitor the feed rate in real time, ensuring accurate proportioning. Pipelines are connected via quick-connect couplings for easy disassembly, replacement, and maintenance. An additional two-way cleaning pipeline allows for flushing of the inlet pipe after operation, preventing residual blockages or cross-contamination, thus improving operational convenience and the system's sustainable operation.
