Description

Technical Field

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

[0002] When testing the viscosity of water-based inks, the Zein cup method can be used. Using the Zein cup is a common and rapid on-site testing method for water-based ink viscosity, simple to operate and suitable for viscosity monitoring during production. The specific operation is as follows: The Zein cup is a cylindrical metal cup (usually made of stainless steel or aluminum alloy) with a fixed-diameter hole at the bottom and graduations on the body (used to confirm ink volume). Select the appropriate Zein cup model according to the viscosity range of the water-based ink; different models have different hole diameters and capacities. Ensure the water-based ink sample is uniform and free of sediment. Control the sample temperature at 25±1℃. Place the Zein cup vertically on a fixed support with the opening facing upwards until the ink level exceeds the graduations. Hold the boom with your left hand and a stopwatch with your right hand, placing the ink container directly below the opening of the cup. Release the ink and start timing, ensuring the ink flows freely from the bottom hole. Observe the ink flow: when the flow changes from continuous to droplets or is interrupted, immediately stop the stopwatch and record the time. After each measurement, thoroughly clean the Zein cup and repeat the operation three times, taking the average value.

[0003] During the actual operation of the above experiment, the hand holding the Zein cup rod is unstable and prone to shaking, which in turn causes the Zein cup to shake. The shaking of the Zein cup causes fluctuations in the ink level inside the cup and unstable flow velocity at the bottom channel; this leads to deviations in the judgment of the timing start and end points, reducing the reliability of the test results. Utility Model Content

[0004] The purpose of this invention is to provide a water-based ink viscosity testing device to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a water-based ink viscosity testing device is provided, comprising a Zein cup. Guide rods are fixedly arranged on both sides of the Zein cup, and a limiting seat is installed below the guide rods. The bottom of the guide rods passes through the limiting seat and is connected to the side wall of the Zein cup. Guide seats are fixedly arranged at both ends of the limiting seat. A through hole is opened inside the guide seat. Support frames are fixedly connected to both sides of the bottom of the limiting seat. A base is fixedly arranged at the bottom of the support frame. An ink bucket is placed on the base and is positioned directly below the Zein cup. A base is installed at the bottom of the Zein cup. Equally spaced force-bearing plates are fixedly arranged on the outer circumference of the base. A leakage hole is opened at the bottom of the base.

[0006] Furthermore, the Zein cup also includes a foam removal sheet, filter holes, and spikes. The top of the Zein cup is covered with a foam removal sheet, and the foam removal sheet has filter holes evenly distributed at equal intervals. The height of the Zein cup is less than the height of the ink barrel, and the inner diameter of the Zein cup is less than the inner diameter of the ink barrel.

[0007] Furthermore, the upper and lower surfaces of the foam removal plate are uniformly provided with multiple sets of spikes. The foam removal plate is circular. The base below the Zein cup has a semi-circular cross-section. A screw sleeve is fixedly provided at the upper end of the base. The screw sleeve is screwed and fixed to the inner circumference of the bottom of the Zein cup.

[0008] Furthermore, the guide rod is U-shaped, and its two ends are respectively inserted into two sets of guide holes on the limiting seat. The limiting seat also includes a locking plate and an operating plate. The operating plate has a T-shaped cross-section, and a locking plate is fixedly installed on the inner wall of the operating plate. The guide rod is respectively provided with a detection limiting plate and an immersion limiting plate.

[0009] Furthermore, the diameters of the detection limiting plate and the immersion limiting plate are larger than the diameter of the guide hole, and locking holes are provided near the detection limiting plate and the immersion limiting plate. The locking holes are provided through the guide rod, and the locking plate passes through the through hole and is inserted into the inside of the locking hole.

[0010] Furthermore, a positioning groove is provided at the center of the base surface, and the bottom of the ink barrel is inserted into the positioning groove. The base is a circular structure made of metal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses spikes on the upper and lower surfaces of the foam removal sheet to puncture the surface foam when ink flows through. The tips of the spikes destroy the bubble film structure, causing the foam to break. The filter holes filter through the pore size and use surface tension to block larger foam from passing through. The spikes and filter holes work together to improve the efficiency of breaking bubbles. The spikes reduce the foam adhesion area, reduce the residual rate of foam on the removal sheet, and avoid foam interference with detection.

[0013] 2. This utility model detects that when the limiting plate abuts against the bottom of the limiting seat, the locking plate passes through the through hole and inserts into the locking hole, forming a mechanical locking structure. This eliminates minor vibrations during hand operation and, in particular, avoids interference from the cup body shaking during the testing process on the ink flow state, ensuring a uniform and stable ink flow rate and making the recording of the flow interruption time more accurate. The cooperation between the limiting seat and the guide rod simplifies the positioning process of the Zein cup, eliminating the need for repeated adjustments to verticality. The locking plate insertion action can quickly complete the fixing, shortening the preparation time for single-batch testing and improving testing efficiency and the accuracy of ink viscosity testing.

[0014] 3. This utility model can adapt to the detection of materials with different viscosity ranges by replacing the base with different diameter orifices, without replacing the entire Zein cup, thus reducing equipment costs; different specifications can be quickly switched according to detection needs, improving detection efficiency; different diameter orifices can match the viscosity characteristics of materials, so that the ink outflow time is within a reasonable detection range, avoiding excessively long or short outflow time due to improper orifice diameter, and ensuring the accuracy of viscosity detection results.

[0022] Please see Figure 1-6 This utility model provides a water-based ink viscosity testing device, including a Zein cup 4. Guide rods 5 are fixedly installed on both sides of the Zein cup 4. A limiting seat 7 is installed below the guide rods 5. The bottom of the guide rods 5 passes through the limiting seat 7 and is connected to the side wall of the Zein cup 4. Guide seats 71 are fixedly installed at both ends of the limiting seat 7. Through holes 72 are opened inside the guide seats 71. Support frames 3 are fixedly connected to both sides of the bottom of the limiting seat 7. A base 1 is fixedly installed at the bottom of the support frame 3. An ink bucket 2 is placed on the base 1. The ink bucket 2 is located directly below the Zein cup 4. A base 41 is installed at the bottom of the Zein cup 4. Equally spaced force plates 42 are fixedly installed on the outer circumference of the base 41. A leakage hole 412 is opened at the bottom of the base 41.

[0023] In a preferred embodiment, the Zein cup 4 also includes a foam removal sheet 43, filter holes 44 and spikes 45. The top of the Zein cup 4 is covered with the foam removal sheet 43, and the filter holes 44 are evenly distributed on the foam removal sheet 43. The height of the Zein cup 4 is less than the height of the ink tank 2, and the inner diameter of the Zein cup 4 is less than the inner diameter of the ink tank 2.

[0024] like Figure 4 and Figure 5 As shown: The top of the Zein cup 4 is covered with a foam removal plate 43. The foam removal plate 43 has evenly distributed filter holes 44. Multiple sets of spikes 45 are evenly arranged on the upper and lower surfaces of the foam removal plate 43. The spikes 45 on the upper and lower surfaces of the foam removal plate 43 can puncture the surface foam when the ink flows through. The tips of the spikes 45 destroy the bubble film structure, causing the foam to break. The filter holes 44 filter through the pore size and use surface tension to block larger foam from passing through. The spikes 45 and the filter holes 44 work together to improve the efficiency of breaking bubbles. The spikes 45 reduce the foam adhesion area, and the through design of the filter holes 44 prevents foam retention. Compared with a smooth surface, the residual rate of foam on the removal plate is reduced, avoiding secondary foam interference with detection.

[0025] In a preferred embodiment, the upper and lower surfaces of the foam removal plate 43 are uniformly provided with multiple sets of spikes 45. The foam removal plate 43 is circular. The base 41 below the Zein cup 4 has a semi-circular cross section. A screw sleeve 411 is fixedly provided at the upper end of the base 41. The screw sleeve 411 is screwed and fixed to the inner wall of the bottom circumference of the Zein cup 4.

[0026] like Figure 4 and Figure 5 As shown: The base 41 has a drain hole 412 at its bottom. The base 41 is screwed to the inner circumference of the bottom of the Zein cup 4 by a screw-on sleeve 411. By replacing the base 41 with drain holes 412 of different diameters, it can be adapted to the detection of materials with different viscosity ranges, meeting diverse detection needs without replacing the entire Zein cup 4, thus reducing equipment costs. The screw-on sleeve 411 fixing method facilitates quick disassembly and installation of the base. The setting of multiple sets of equidistantly distributed force plates 42 facilitates the force rotation of the base 41. The replacement process is simple and efficient, and different specifications can be quickly switched according to detection needs, improving detection efficiency. Drain holes of different diameters can match the viscosity characteristics of materials, so that the ink outflow time is within a reasonable detection range, avoiding excessively long or short outflow times due to improper drain hole diameter, and ensuring the accuracy of viscosity detection results.

[0027] In a preferred embodiment, the guide rod 5 is U-shaped, with its two ends inserted into two sets of guide holes 70 on the limiting seat 7. The limiting seat 7 also includes a locking piece 73 and an operating plate 74. The operating plate 74 has a T-shaped cross-section, and the locking piece 73 is fixedly installed on the inner wall of the operating plate 74. The guide rod 5 is provided with a detection limiting piece 6 and an immersion limiting piece 61.

[0028] The diameters of the detection limit plate 6 and the immersion limit plate 61 are larger than the diameter of the guide hole 70. Locking holes 62 are provided near the detection limit plate 6 and the immersion limit plate 61. The locking holes 62 are provided through the guide rod 5. The locking plate 73 passes through the through hole 72 and is inserted into the inside of the locking hole 62.

[0029] like Figure 4 As shown: The connection between guide rod 5 and Zein cup 4 is as follows: the end of guide rod 5 passes through the guide hole 70 opened on the limiting seat 7 and is inserted into the arc plate welded and fixed on the side wall of Zein cup 4. At this time, the arc plate and the end of guide rod 5 are fixed by welding. The setting of the arc plate can increase the stability of guide rod 5 and Zein cup 4 after welding. There are two sets of guide holes 70. The depth of guide holes 70 is the same as the height of limiting seat 7. The two sets of guide holes 70 are opened on the inside of the limiting seat 7 on both sides. The bottom sides of guide rod 5 pass through the two sets of guide holes 70 respectively. This can limit and guide guide rod 5 and Zein cup 4 during lifting and lowering, and prevent Zein cup 4 from shaking during lifting and lowering.

[0030] like Figure 1 , Figure 2 and Figure 3As shown: The guide rod 5 is inserted into the guide holes on the limiting seat 7 at both ends, which can strictly limit the left and right swaying during the lifting and lowering of the Zein cup 4, ensuring that the cup body is vertically immersed in the ink tank 2, avoiding flow rate errors caused by tilting, and ensuring the accuracy of viscosity detection benchmark; When the detection limiting piece 6 touches the bottom of the limiting seat 7, the locking piece 73 passes through the through hole 72 and inserts into the locking hole 62, forming a mechanical locking structure, eliminating the slight shaking during hand operation, especially avoiding the interference of cup body shaking on the ink flow state during the detection process, making the recording of the flow interruption time more accurate; The cooperation between the limiting seat 7 and the guide rod 5 simplifies the positioning process of the Zein cup 4, eliminating the need for repeated adjustments to verticality, and the insertion action of the locking piece 73 can be quick Once fixed in place, the preparation time for single-batch testing is shortened, improving testing efficiency. The precise fit between the rigid guide rod 5 and the limiting hole ensures long-term positioning accuracy. Similarly, when the immersion limiting plate 61 covers the upper surface of the limiting seat 7, the end of the locking plate 73 is inserted into the locking hole 62 at the bottom of the immersion limiting plate 61, preventing the Zein cup 4 from shaking inside the ink container 2 and reducing the amount of foam generated. This reduces foam generated by the cup body disturbing the ink, preventing foam from affecting the ink flow rate and the judgment of the flow interruption time, and improving the accuracy of viscosity testing data. The stable fixing structure reduces the probability of repeated testing due to foam interference during the testing process, improving testing efficiency.

[0031] As a preferred embodiment, a positioning groove is provided at the center of the surface of the base 1, and the bottom of the ink bucket 2 is inserted into the positioning groove. The base 1 is a circular structure made of metal.

[0032] Working principle: In actual use, hold the upper side of the guide rod 5 and immerse the Zein cup 4 at the bottom of the guide rod 5 inside the ink container 2. The size of the ink container 2 is larger than the size of the Zein cup 4. The ink level should be a certain height below the opening of the container to avoid overflow. After the Zein cup 4 is immersed in the ink container 2, the ink inside the ink container 2 will not overflow. When the Zein cup 4 is full of ink, hold the guide rod 5 and place the Zein cup 4 above the ink container 2 while starting a stopwatch. Record the time it takes for the ink to flow from the bottom of the cup to stop flowing. This time is the ink viscosity value for the corresponding specification of the Zein cup. During the test, it is important to control the ambient temperature, usually 25°C. ±1℃, and ensure proper operation to guarantee data accuracy; when the Zein cup 4 is used with this equipment, the two ends of its guide rod 5 are respectively inserted into the two sets of guide holes 70 opened on the limit seat 7, which can limit and guide the Zein cup 4 during lifting and lowering. When the immersed limit plate 61 abuts against the bottom surface of the limit seat 7, the operator can hold the operating plate 74 and insert the locking plate 73 through the through hole 72 into the locking hole 62 above the detection limit plate 6. This can ensure the stability of the Zein cup 4 when it is stationary, and prevent the Zein cup 4 from shaking due to hand tremors when detecting ink viscosity, thereby improving the accuracy of ink viscosity detection.

[0033] like Figure 4 and Figure 5 As shown: When assembling the Zein Cup 4, first hold the base 41 and screw the screw sleeve 411 on the top of the base 41 into the screw groove at the bottom of the Zein Cup 4. To increase the sealing between the screw sleeve 411 and the bottom of the Zein Cup 4, raw rubber tape can be wrapped around the outside of the screw sleeve 411. The foam removal plate 43 is circular, and a circular filter with filter holes 44 is set in the middle of the foam removal plate 43. The filter protrudes downward and is inserted into the inner wall of the top circumference of the Zein Cup 4, thus completing the assembly of the Zein Cup 4.
