Description

Technical Field

[0001] This utility model belongs to the field of pH testing technology for water-based inks, and particularly relates to a pH tester for water-based ink production. Background Technology

[0002] Water-based inks, often simply called water-based inks, with flexographic water-based inks also known as liquid inks, are primarily made from water-soluble resins, organic pigments, solvents, and related additives through a precise composite grinding process. Due to their environmentally friendly properties and excellent printing results, water-based inks are particularly suitable for packaging printing products with extremely strict hygiene requirements, such as tobacco, alcohol, food, beverages, pharmaceuticals, and children's toys.

[0003] However, accurately measuring the pH value of water-based inks is crucial for ensuring product quality during production, yet it is also a challenging task. While traditional pH meters can meet basic measurement needs functionally, they reveal some significant problems in practical applications. Especially when dealing with viscous or difficult-to-stir water-based inks, the test tip often struggles to quickly and evenly contact all parts of the ink, directly leading to potentially inaccurate measurement results and affecting the assessment of product quality.

[0004] Furthermore, cleaning and maintaining the testing instruments after use also presents challenges. Water-based inks tend to adhere to and dry on the instrument surface, especially critical areas such as the test tips. This not only increases the difficulty of cleaning but may also adversely affect the long-term stability and accuracy of the instrument.

[0005] Therefore, it is essential to invent a pH tester for the production of water-based inks. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a pH tester for water-based ink production, comprising a pH tester body, a test head, a test end, a detachable agitator, threads, a locking cylinder, a main display panel, control buttons, a secondary panel, and a sealing cylinder. The test head, i.e., a glass electrode, is integrally mounted on the test head of the pH tester body. The threads on the surface of the test head engage with the locking cylinder, securing the detachable agitator to the test head. The main display panel and control buttons are located on the surface of the pH tester body, with a secondary panel at the upper end of the main display panel. The sealing cylinder allows engagement with the threads on the surface of the test head and encloses the test head within it.

[0007] Preferably, the detachable agitator includes a housing, an agitating disc, a belt, a drive disc, a drive motor, and an assembly cylinder. The housing and the assembly cylinder are integrally formed. The assembly cylinder is fitted over the test head and is secured to the test head by the locking cylinder. The agitating disc is rotatably mounted on the assembly cylinder. The agitating disc is located inside the housing. Belts are mounted on the agitating disc and the drive disc. The drive disc is rotatably mounted inside the housing. The output end of the drive motor, which is fixedly mounted outside the housing, is fixed to the drive disc.

[0008] Preferably, a plurality of agitating plates arranged in a circular array are fixedly installed on the lower surface of the agitating disc, the agitating plates being inclined as a whole and having a rectangular plate structure.

[0009] Preferably, several of the agitators are located around the test head, test end, and locking cylinder, and the four do not interfere with each other. The agitators are allowed to be inserted into the water-based ink together with the test end.

[0010] Preferably, the upper surface of the locking cylinder only contacts the assembly cylinder, and the outer shell is restricted by contact with the assembly cylinder.

[0011] Preferably, the agitator disc rotatably mounted on the assembly cylinder is arranged opposite to the drive disc, and the diameter of the agitator disc is smaller than the diameter of the drive disc.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model relates to a pH tester for water-based ink production. Through the ingenious combination of an integrated test head and a detachable agitator on the main body of the tester, it achieves effective stirring of the water-based ink during testing. This design ensures that the test head (glass electrode) can uniformly contact all parts of the ink, thereby significantly improving the accuracy of the measurement.

[0014] Furthermore, the detachable agitator of this invention is not only easy to operate, but also allows for quick disassembly after testing, facilitating thorough cleaning and laying a solid foundation for the accuracy of subsequent tests. It also ensures the continuous accuracy of testing and the long service life of the instrument. At the same time, it can be disassembled when not in use, thereby reducing the overall size of the instrument and making it convenient for use in special situations.

[0015] This invention features several circularly arrayed agitator plates fixedly mounted on the lower surface of the agitator disc. Their overall inclined arrangement effectively agitates the ink from the periphery towards the center, further ensuring full contact between the test tip and the ink. This design not only improves agitation efficiency but also ensures that the agitator plates, test head, test tip, and locking cylinder do not interfere with each other, allowing them to be inserted into the water-based ink simultaneously, greatly enhancing testing convenience. At the same time, the inclined arrangement of the agitator plates reduces resistance during agitation, making the agitation smoother. Attached Figure Description

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a pH tester for water-based ink production, comprising a pH tester body 1, a test head 2, a test end 3, a detachable agitator 4, a thread 5, a locking cylinder 6, a main display panel 7, control buttons 8, a secondary panel 9, and a sealing cylinder 10. The test head 2, integrally mounted on the pH tester body 1, is provided with a test end 3, i.e., a glass electrode. The thread 5 on the surface of the test head 2 engages with the locking cylinder 6, and restricts the detachable agitator 4 onto the test head 2. The main display panel 7 and control buttons 8 are provided on the surface of the pH tester body 1, and the secondary panel 9 is provided at the upper end of the main display panel 7. The sealing cylinder 10 allows engagement with the thread 5 on the surface of the test head 2 and encloses the test head 2 within it.

[0025] Furthermore, the detachable agitator 4 includes a housing 41, an agitating disc 42, a belt 43, a drive disc 44, a drive motor 45, and an assembly cylinder 47. The housing 41 and the assembly cylinder 47 are integrally designed from metal or rigid plastic, ensuring structural stability and overall aesthetics. The assembly cylinder 47 is cleverly fitted onto the outside of the test head 2 and is securely restrained on the rubber-plastic test head 2 through a tight fit with the locking cylinder 6. This design ensures the stability of the agitator while facilitating its disassembly and cleaning.

[0026] Furthermore, an agitator disc 42 is rotatably mounted on the assembly cylinder 47, located inside the outer casing 41. Several circularly arranged agitator plates 46 are fixedly mounted on the lower surface of the agitator disc 42. These agitator plates 46 are made of corrosion-resistant plastic material and are inclined as a whole, employing a rectangular plate structure. This design allows the agitator plates 46 to more effectively agitate the water-based ink when rotating, ensuring that the test tip 3 can uniformly contact all parts of the ink. The number and tilt angle of the agitator plates 46 have been carefully calculated to achieve the best agitation effect.

[0027] Furthermore, several agitator plates 46 are located around the test head 2, test end 3, and locking cylinder 6, without interfering with each other. This layout allows the agitator plates 46 to be inserted into the water-based ink along with the test end 3 for synchronized agitation and measurement. During agitation, the agitator plates 46 effectively stir the ink from the periphery towards the center, ensuring that the test end 3 can fully contact the ink, thereby improving measurement accuracy.

[0028] Furthermore, the locking cylinder 6 plays a crucial role in securing the agitator. Its upper surface only contacts the mounting cylinder 47, and through a tight fit with the mounting cylinder 47, it effectively restricts the movement of the outer casing 41. This design not only ensures the stability of the agitator during testing but also facilitates quick disassembly of the agitator for cleaning and maintenance after testing.

[0029] Furthermore, inside the agitator, the agitating disc 42 and the driving disc 44 are positioned opposite each other, with the diameter of the agitating disc 42 being smaller than that of the driving disc 44. This design allows the drive motor 45 to efficiently drive the rotation of both the agitating disc 42 and the agitating plate 46 by rotating the driving disc 44. A belt 43 serves as the transmission medium, connecting the agitating disc 42 and the driving disc 44, ensuring smooth power transmission. This structural design not only improves the agitation efficiency of the agitator but also guarantees its operational stability and reliability.

[0030] The working principle is as follows: First, the sealing cylinder 10 is removed from the test head 2 to allow for the assembly of the detachable agitator 4. This step is to provide sufficient operating space for the agitator when it is necessary to agitate the water-based ink for more accurate pH measurement.

[0031] Next, assemble the detachable agitator 4. Place the assembly sleeve 47 over the outside of the test head 2. Then, screw the locking sleeve 6 onto the thread 5 of the test head 2 until the upper surface of the locking sleeve 6 is in tight contact with the assembly sleeve 47. This tight fit not only restricts the movement of the outer casing 41, thus ensuring the stability of the agitator 4 during testing, but also facilitates quick disassembly of the agitator 4 for cleaning and maintenance after testing.

[0032] After the agitator 4 is assembled, the drive motor 45 is started. The output end of the drive motor 45 is fixed to the drive disc 44, so when the motor starts, it will drive the drive disc 44 to rotate. Since the agitator disc 42 and the drive disc 44 are connected by a belt 43, the rotation of the drive disc 44 will be efficiently transmitted to the agitator disc 42, thereby driving the agitator plate 46 on the lower surface of the agitator disc 42 to rotate.

[0033] The number and tilt angle of the agitator plates 46 are carefully calculated to ensure more effective agitation of the water-based ink during rotation. As they rotate, these plates 46 agitate the ink from the periphery towards the center, ensuring that the test tip 3 (i.e., the glass electrode) makes full contact with all parts of the ink. This agitation method not only improves measurement accuracy but also helps reduce measurement errors caused by ink inhomogeneity.

[0034] While the agitator 4 is agitating, the pH value of the water-based ink can be obtained by observing the reading on the main display panel 7. If more detailed measurement information or parameter settings are needed, they can be operated via the control button 8, while the sub-panel 9 provides additional display space for users to more easily view relevant information.

[0035] After the test is completed, first turn off the drive motor 45, then remove the locking cylinder 6 and the removable agitator 4. If the tester needs to be stored, the sealing cylinder 10 can be tightened back onto the thread 5 of the test head 2 after cleaning to protect the test end 3 from the influence of the external environment.

[0036] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
