Description

Technical Field

[0001] This utility model belongs to the field of water-based ink testing technology, and in particular relates to a water-based ink filterability testing device. Background Technology

[0002] Water-based ink is a type of water-soluble ink. Its main ingredients include resins such as acrylic resin, pigments, and various auxiliary agents such as dispersants. During the production and processing of water-based ink, after the materials are mixed in the mixing equipment, a filtration test is required to assess the dissolution and dispersion effect of the materials, i.e., to determine the uniformity of the water-based ink.

[0003] Specifically, if the particle crushing and dissolution effect is not high during the formulation of water-based inks, the uniformity of the water-based inks will be low, and the filtration resistance will be relatively high during the filtration process. As a result, the ink will clog the nozzles, spray pipes and other structures due to the high particle content during use.

[0004] Therefore, filtration testing can not only effectively detect the uniformity of ink, but also accurately rework inks with unsatisfactory solubility.

[0005] The current testing methods include sampling filtration testing and finished product filtration testing. Sampling filtration testing involves taking samples of the mixed materials during the batching process and then filtering them. For materials with significantly poor filtration (insufficient dispersion of the ink, resulting in a large amount of particulate matter), it is necessary to extend the stirring and dissolving time, increase the stirring intensity, and raise the stirring temperature. Therefore, a large number of samples are tested, resulting in a relatively large testing volume.

[0006] Currently, the workshop's testing method involves taking samples and then pumping the sample ink into a filter using a liquid pump. This method of testing each sample individually is not only inefficient, but also results in the inability to centrally store the ink generated during the testing process.

[0007] Meanwhile, during the test, because the ink was prepared by hot stirring, it cooled easily, making it impossible to accurately determine the uniformity of the hot-stirred ink system. This manifested as decreased filtration after the ink cooled, making it impossible to determine whether the stirring temperature of the hot-stirred vessel needed to be increased. Therefore, under the premise of simulating the stirring temperature, the poor filtration performance of the hot filtration test necessitates guidance to increase the stirring temperature. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a water-based ink filterability testing device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A water-based ink filterability testing device includes an ink filterability testing mechanism, wherein the ink filterability testing mechanism includes a testing platform, an ink thermal filtration testing structure is installed on the testing platform, the ink thermal filtration testing structure includes a hot water cylinder, a plurality of ink heating structures are installed on the hot water cylinder, and the ink heating structure includes a storage ball located inside the hot water cylinder;

[0011] The top of the storage ball is connected to an inlet pipe that passes through the hot water cylinder, and the bottom of the storage ball is connected to an outlet pipe that passes through the hot water cylinder. The outlet pipe is equipped with a filter.

[0013] The test platform is equipped with a receiving box, which is fitted with several discharge nozzle connectors that cooperate with the discharge nozzles.

[0014] Preferably, the front and rear ends of the hot water tank are respectively connected to a pump pipe and a water outlet pipe, and both the pump pipe and the water outlet pipe are equipped with valves.

[0019] Preferably, the movable frame is mounted on the test platform via a horizontally movable structure.

[0020] Preferably, the horizontal moving structure includes moving grooves respectively opened on the front and rear sides of the top of the test platform;

[0021] The bottom of the mobile frame is fixedly installed with a movable slide block that is slidably connected to the movable slide groove;

[0029] This utility model has the following beneficial effects:

[0030] 1. During the operation, multiple samples are pumped into the ink heating structure via liquid pumps. The oil pump then enters the storage sphere for heating. Subsequently, the ink in the larger storage sphere is heated in a water bath until it reaches near the temperature of the stirred tank. The oil pump, propelled by the liquid pump, enters the filter. For ink materials with insufficient solubility (specifically, poor stirring and dissolution resulting in excessive particulate matter content), the filtration resistance is high, and some may even fail to pass through the filter. In such cases, the workshop is instructed to extend the reaction stirring time and increase the mixing temperature.

[0031] 2. Enables efficient and convenient sampling and simultaneous testing of multiple samples of the prepared ink, allowing for extremely convenient and efficient testing of the filtration characteristics of the sample ink.

Following the existing method, a discharge pipe (equipped with a valve) is installed on the front wall of the receiving box to facilitate discharge. This method allows for rapid connection of the discharge nozzle connector during the filtration and testing process, thereby improving testing efficiency. Attached Figure Description

[0043] Example 1

[0044] like Figure 1-5 As shown, a water-based ink filterability testing device includes an ink filterability testing mechanism, which includes a testing platform 1 on which an ink thermal filterability testing structure is installed. The ink thermal filterability testing structure enables the testing of the filterability of sampled ink during the ink formulation preparation process (especially for ink formulations with new processes or formulas where the process is unstable; sampling tests are used to track the mixing, stirring, and dissolving process during ink preparation).

[0045] Specifically, the ink thermal filtration test structure includes a hot water cylinder 31 (with a pump pipe and an outlet pipe connected to its front and rear ends, respectively, both equipped with valves). A heating resistor 311 is fixedly installed on the hot water cylinder 31 using an existing heating method. This heats the water inside the hot water cylinder 31 to the same temperature as the reactor. Following existing methods, a temperature detector (not shown in the figure) is installed on the hot water cylinder 31, with its temperature probe located inside the cylinder and the instrument located outside.

[0046] Meanwhile, a number of ink heating structures 32 are installed on the hot water cylinder 31, and the ink heating structure 32 includes a storage ball 323 located inside the hot water cylinder 31.

[0047] Specifically, the top of the storage ball 323 is connected to an inlet pipe 321 that penetrates the hot water cylinder 31 (to facilitate pumping oil into the storage ball 323, the inlet pipe 321 is integrally formed with an inlet nozzle 322; during testing, the flexible hose connected to the outlet end of the liquid pump is tightened into the inlet nozzle 322). The bottom of the storage ball 323 is connected to an outlet pipe that penetrates the hot water cylinder 31, and the outlet pipe is equipped with a filter 324. Additionally, according to existing methods, a valve is installed on the outlet pipe.

[0048] Specifically, the discharge pipe is connected to the filter 324 via flange 3211. Similar to existing filters, filter 324 includes a housing and a filter element (not shown in the figure) installed inside the housing.

[0049] Meanwhile, a tapered discharge nozzle 325 is connected to the discharge end of the filter 324.

[0050] During operation, multiple samples are pumped into the ink heating structure 32 via liquid pumps, and then into the storage ball 323 for heating. The larger storage ball 323 is then heated in a water bath, bringing the ink to near the temperature of the stirred tank. Following the existing method, the oil pump, driven by a liquid pump (not shown in the diagram), enters the filter 324. For ink materials with insufficient solubility (specifically, poor stirring and dissolution, resulting in excessive particulate matter content), the filtration resistance is high, and some may even fail to pass through the filter 324. In such cases, the workshop is instructed to extend the reaction stirring time and increase the mixing temperature.

[0051] Meanwhile, by heating the hot water tank 31, the filtration speed is accelerated, which guides the heating of the mixing vessel.

[0052] During the testing process, a receiving box 2 is installed on the testing platform 1 to receive the ink after testing (which will then be added back into the reactor). The receiving box 2 is equipped with several discharge nozzle connectors 22 that mate with the discharge nozzles 325. Specifically, the discharge nozzle connectors 22 have interfaces. To improve sealing, the discharge nozzle connectors 22 are made of rubber. When the discharge nozzle 325 is inserted into the interface of the discharge nozzle connector 22, it maintains a seal under elastic compression.

[0053] Meanwhile, several glass observation mirrors 21 are fixedly connected to the top of the receiving box 2. The flowability of the ink pumped into the receiving box 2 can be observed through the glass observation mirrors 21. For example, if the discharge nozzle connector 22 has obviously low flowability or does not flow, it indicates that the filterability of the corresponding sample is poor and that the content of particulate matter that is the solvent in the sample is high.

[0054] The above method enables efficient and convenient sampling and simultaneous testing of multiple samples of the prepared ink, allowing for a highly convenient and efficient assessment of the filtration characteristics of the sample ink.

[0055] Example 2

[0056] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, to facilitate switching the position of the discharge nozzle 325 to align with the discharge nozzle connector 22 on the receiving box 2 during the testing process, rotating arms 34 are rotatably connected to the front and rear ends of the hot water cylinder 31, respectively. The rotating arms 34 are fixedly connected to the ends of the hot water cylinder 31 via connecting frames 33 spaced apart on both sides. The rotating arms 34 are rotatably connected to an L-shaped movable frame 351. Specifically, in the existing manner, a rotating shaft is fixedly connected to the rotating arm 34, and the rotating shaft is rotatably connected to the movable frame 351.

[0057] Meanwhile, a drive motor 35 is installed on the mobile frame 351. As in the existing method, the output shaft of the drive motor 35 is fixedly installed on the rotating shaft, such as by a coupling.

[0058] During the process of introducing the oil pump, keep the feed pipe 321 facing upwards to facilitate the oil pump entering the storage ball 323. Then, switch the discharge nozzle connector 22 from the bottom vertical state to the left side receiving box 2 in the manner described above.

[0059] In order to connect the discharge nozzle connector 22 to the discharge nozzle connector 22, the aforementioned movable frame 351 is installed on the test platform 1 through a horizontal moving structure.

[0060] Specifically, the horizontal moving structure includes movable slides respectively opened on the front and rear sides of the top of the test platform 1; correspondingly, the bottom of the moving frame 351 is fixedly installed with a movable slide block that is slidably connected to the movable slide.

[0061] Meanwhile, the horizontal moving structure also includes a cylinder structure for driving the moving slide. The cylinder structure includes a cylinder 4 fixedly installed on the left side wall of the test platform 1. The piston rod of the cylinder 4 is fixedly connected to a drive rod 41, which is located in the moving slide groove and is fixedly installed on the moving slide.

[0062] During the test, when cylinder 4 operates, the drive lever drives the movable slide block, carrying the movable slide groove, to move to the left and connect to the discharge nozzle connector 22. At this time, with the assistance of the liquid pump, the sampled ink is pumped and filtered for testing. The ink produced during testing is located in the receiving box 2. According to the existing method, a discharge pipe 23 (equipped with a valve) is installed on the front wall of the receiving box 2 to achieve material discharge.

[0063] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
