Description

Technical Field

[0001] The invention relates to the technical field of viscosity detectors, in particular to a viscosity detector for a defoaming agent. Background Art

[0002] Defoaming agent is a food additive that reduces surface tension, inhibits foam generation or eliminates generated foam during food processing. Generally, after its production is completed, a viscosity tester is needed to test the viscosity of the defoaming agent. For example, in the patent application number "CN202211239799.0" and the name of "A paint viscosity detection device", the second observation part includes a fixed block, the bottom end of the fixed block is connected to a vibrating rod through a first telescopic rod, a second cup body is provided directly below the vibrating rod, the second cup body is placed on a base, and observation paper is placed around the second cup body. The base and the middle of the base are respectively provided with a first optical lens and a second optical lens; as can be seen from the above description, the paint is loaded into the second cup body, the first telescopic rod is extended to extend the vibrating rod into the paint, the vibrating rod works to drive the paint to generate ripples, the second optical lens records the amplitude of the ripples, and the first optical lens records the height of the paint on the cup wall of the first cup body and the paint on the observation paper around the base; the observation paper on the base can observe the spilled paint on the one hand, and on the other hand, it can also prevent the paint from contaminating the base. However, the above structure still has the following problems in actual use:

[0003] When conducting viscosity test on defoamer, it is necessary to ensure that the uniformity of the upper, middle and lower layers of the defoamer remains consistent. Since the upper layer of defoamer is relatively thin and the lower layer is relatively viscous during transportation, the vibrating rod or traditional stirring rod mechanism cannot stir the defoamer in the upper, middle and lower layers evenly and fully, and the stirring effect is poor. Therefore, it is easy to have inaccurate test results during testing.

[0004] Therefore, we proposed that the viscosity testing machine of defoaming agent can solve the above problems well. Summary of the invention

[0005] The purpose of the present invention is to provide a viscosity testing machine for a defoaming agent, so as to solve the problem raised in the above background technology that in the current market, due to the upper layer of defoaming agent being relatively thin and the lower layer being relatively thick during transportation, a vibrating rod or a traditional stirring rod mechanism cannot be used to stir the defoaming agent in the upper, middle and lower layers evenly and fully, resulting in a poor stirring effect.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0037] Embodiment 1: In order to solve the problem in the prior art that the defoaming agent in the upper layer is relatively thin and the lower layer is relatively viscous during transportation, the vibrating rod or the traditional stirring rod mechanism cannot be used to stir the defoaming agent in the upper, middle and lower layers evenly and fully, and the stirring effect is poor, so it is easy to have inaccurate detection results during detection. Therefore, the following scheme is disclosed, including a base 1, and a support frame 2 is fixed on the upper surface of the base 1; and further comprising: a first servo motor 3 is fixed on the upper end surface of the support frame 2, and a first servo motor 3 is fixed on the output end The threaded rod 4 is provided, and the lower end of the first threaded rod 4 passes through the support frame 2 and extends into the base 1, and the outer side surface of the first threaded rod 4 is threadedly connected with a connecting beam 5; two groups of connecting beams 5 are provided, and the right connecting beam 5 and the support frame 2 form a sliding connection, and the inner ends of the two groups of connecting beams 5 are fixed to a fixed box 6, and a second servo motor 7 is fixed to the upper surface of the fixed box 6, and at the same time, a main shaft 8 is fixed to the output end of the second servo motor 7, and the lower end of the main shaft 8 passes through the fixed box 6, and a stirring mechanism is provided at the lower end of the main shaft 8, and the stirring mechanism includes a connecting plate 9 and a connecting rod 10, and the connecting disk 9 is provided with two groups, and the lower connecting disk 9 is fixed to the lower end of the main shaft 8, and the upper connecting disk 9 is slidably sleeved on the outer side of the main shaft 8, and the outer sides of the two groups of connecting disks 9 are both rotatably connected with the connecting rod 10, and the connecting rod 10 is provided with two groups, and each group is provided with four, and the two groups of connecting rods 10 are rotatably connected to each other at one end away from the connecting disk 9, and the upper surface of the upper connecting disk 9 is fixed with a resistance rod 11, and the upper end of the resistance rod 11 extends to the fixed box 6 and contacts the arc ring 12, and the outer side of the arc ring 12 is wavy The structure is arranged in a shape, and the upper side of the arc ring 12 is fixed to the fixed box 6, and the outer side of the abutting rod 11 is also fixed with a first connecting block 13, and the upper surface of the first connecting block 13 is fixed to the lower end of the tension spring 14, and the upper end of the tension spring 14 is fixed to the lower end surface of the second connecting block 15, and the inner end of the second connecting block 15 is fixedly connected to the main shaft 8, and the outer side of the main shaft 8 is also fixed with a scraper rod 16, and the scraper rod 16 is provided with two groups, and the scraper rod 16 is arranged in a "7" shape, and the outer side of the scraper rod 16 is in contact with the inner wall of the defoaming agent barrel;

[0038] First, the first servo motor 3 is started, so that the first servo motor 3 drives the first threaded rod 4 to rotate. The first threaded rod 4 rotates, so that it drives the threaded connecting beam 5 to descend, so that the connecting beam 5 drives the stirring mechanism to move into the barrel filled with the defoaming agent. Then, the second servo motor 7 can be controlled to start, so that the second servo motor 7 drives the main shaft 8 to rotate. The main shaft 8 rotates, so that the connecting disk 9 is driven to rotate together, so that the connecting disk 9 drives the connecting rod 10 to rotate, and then the defoaming agent is stirred. At the same time, during the rotation of the connecting disk 9, the resistance rod 11 is also driven to rotate. Through the contact between the upper end of the resistance rod 11 and the arc ring 12, the force applied to the resistance rod 11 by the arc ring 12 makes the resistance rod 11 driven by the force to drive the connecting disk 9 fixed at its lower end downward, so that the upper connecting disk 9 moves downward and drives the connecting rod 10 connected to it for rotation to descend together. Through the linkage structure formed by the two groups of connecting rods 10, the connecting rods 10 are brought close to and contracted. The stirring range is increased. At the same time, when the resistance rod 11 rotates into the groove of the arc ring 12, the resistance rod 11 is no longer stressed, and then the elastic force of the tension spring 14 can be used to drive the first connecting block 13 to reset upward, and the first connecting block 13 is used to drive the fixed resistance rod 11 to reset upward, so that the resistance rod 11 drives the upper connecting plate 9 upward, so that the connecting plate 9 drives the connecting rod 10 to shrink, thereby reducing the stirring range. The arc ring 12 is driven to rise and fall reciprocally by the resistance rod 11, and the main shaft 8 is rotated to achieve the stirring effect. At the same time, the repeated shrinkage of the connecting rod 10 also improves the stirring effect, making the stirring more uniform and the stirring effect better, so that the defoaming agent is fully stirred, ensuring that the uniformity of the stirring of the upper and lower layers is the same, and ensuring the accuracy of the detection result. At the same time, the main shaft 8 will also drive the scraper rod 16 to rotate, and the scraper rod 16 is attached to the inner wall of the defoaming agent barrel, so that the defoaming agent adhering to the barrel wall can be scraped off;

[0039] Embodiment 2: Different from Embodiment 1, this embodiment achieves the effect of sealing the mouth of the defoaming agent barrel, thereby preventing the defoaming agent from splashing out of the barrel during stirring, and scraping off the defoaming agent stuck during stirring, thereby completing the cleaning effect of the cover plate 22 without manual cleaning. For details, refer to Figure 6-Figure 7A vertical rod 17 is fixed to the lower surface of the support frame 2, and the lower end of the vertical rod 17 passes through the connecting beam 5 and forms a sliding connection with the connecting beam 5. At the same time, a first tooth block 18 is evenly spaced on the front side of the lower end of the vertical rod 17. At the same time, the first tooth block 18 is meshed with the first gear 19, and the first gear 19 is arranged in the connecting beam 5. A second threaded rod 20 is also fixed in the middle of the first gear 19. Both ends of the second threaded rod 20 are connected to the connecting beam 5 bearings, and the outer side surface of the second threaded rod 20 is also threadedly connected with a sliding plate 21, and the lower end of the sliding plate 21 extends out of the connecting beam 5 and is fixed to the cover plate 22, and the cover plate 22 is provided with two groups, and the two The group cover plate 22 forms a circular structure, and the diameter of the cover plate 22 is larger than the diameter of the defoaming agent barrel. A pull rope 23 is wound around the outer side surface of the inner end of the second threaded rod 20, and the lower end of the pull rope 23 extends into the cover plate 22 and is fixed to the connecting slide rod 24, and the connecting slide rod 24 is slidably arranged on the lower surface of the cover plate 22. At the same time, the connecting slide rod 24 is elastically slidably connected with the cover plate 22 through a return spring 25, and the two ends of the return spring 25 are respectively fixed to the cover plate 22 and the connecting slide rod 24, and the lower end of the connecting slide rod 24 is fixed to the cleaning rod 26, and the cleaning rod 26 is arranged on the lower surface of the cover plate 22, and the upper surface of the cleaning rod 26 is tightly fitted with the lower surface of the cover plate 22;

[0040] At the same time, when the first threaded rod 4 drives the connecting beam 5 to descend, the connecting beam 5 will also drive the first gear 19 downward at the same time. When it descends to a certain position, the first gear 19 will mesh with the first tooth block 18, so that the first gear 19 will rotate by meshing with the first tooth block 18. The first gear 19 rotates by itself, and the second threaded rod 20 is driven to rotate by itself. The second threaded rod 20 rotates, and the threaded sliding plate 21 is driven to move inward by the sliding plate 21, so that the sliding plate 21 drives the cover plate 22 to move inward together, so that the two sets of cover plates 22 are closed, so as to achieve the effect of sealing the defoaming agent barrel mouth, thereby preventing the defoaming agent from splashing out of the barrel during the stirring process. At the same time, when the second threaded rod 20 rotates, the pull rope 23 will be reeled in, so that the pull rope 23 is reeled in and the connecting slide rod 24 is pulled inward, so that the connecting slide rod 24 drives the cleaning rod 26 At the same time, it moves inward. When the stirring is finished, the first threaded rod 4 drives the connecting beam 5 to rise, and the first gear 19 is meshed with the first tooth block 18 again, and the first gear 19 is reversed. Through the reversal of the first gear 19, the second threaded rod 20 is driven to reverse together, so that the second threaded rod 20 is reversed and the cover plate 22 is driven away from each other through the sliding plate 21, so that the cover plate 22 is opened. At the same time, the second threaded rod 20 will also relax the pull rope 23. At this time, the connecting slide rod 24 will no longer be subjected to tension. At this time, the elastic force of the reset spring 25 is used to pull the connecting slide rod 24 to reset, so that the connecting slide rod 24 drives the cleaning rod 26 to reset, and the cleaning rod 26 is fitted with the lower surface of the cover plate 22, so that the cleaning rod 26 cleans the lower surface of the cover plate 22, thereby scraping off the defoaming agent stuck during the stirring process, and then completing the cleaning effect of the cover plate 22 without manual cleaning.

[0041] Embodiment 3: Different from Embodiment 2, this embodiment can firmly fix the defoaming agent barrel, thereby preventing the defoaming agent barrel from shifting during the stirring process. Figure 1 and Figure 8-Figure 10 , the lower end of the first threaded rod 4 is fixed to the second gear 27, and the outer side of the second gear 27 is meshed with the second tooth block 29, and the second tooth block 29 is fixed to the outer side of the turntable 28, and the turntable 28 is arranged inside the base 1, and the turntable 28 and the base 1 are connected by a bearing, and the surface of the turntable 28 is provided with four groups of arc grooves 30, and a moving rod 31 is slidably arranged inside the arc groove 30, and the upper end of the moving rod 31 extends out of the upper surface of the base 1 and is slidably connected with the base 1, and a limiting plate 32 is fixed to the inner side of the upper end of the moving rod 31, and the limiting plate 32 is arranged in an arc-shaped structure, and an anti-skid pad 33 is bonded to the inner side of the limiting plate 32, and the anti-skid pad 33 is in contact with the outer wall of the defoaming agent barrel;

[0042] And the first threaded rod 4 will also drive the second gear 27 to rotate, through the meshing between the second gear 27 and the second tooth block 29, and through the fixation between the second tooth block 29 and the rotating disk 28, the second tooth block 29 drives the rotating disk 28 to rotate through the second tooth block 29, and then the rotating disk 28 drives the arc groove 30 to rotate synchronously, through the sliding connection formed between the arc groove 30 and the moving rod 31, and through the sliding connection formed between the moving rod 31 and the base 1, the moving rod 31 is moved inward, and through the moving rod 31 moving inward, the moving rod 31 drives the limiting plate 32 fixed on the inner side of its upper end to approach the defoaming agent barrel at the same time, thereby realizing the limitation of the defoaming agent barrel, and through The anti-skid pad 33 on the inner side of the limit plate 32 has an anti-skid effect, so that the defoaming agent barrel can be firmly fixed, thereby avoiding the displacement of the defoaming agent barrel during the stirring process and ensuring the stirring effect. The second tooth block 29 is only provided with a quarter of the turntable 28. Therefore, when the rotation angle of the turntable 28 is limited, it is avoided that the turntable 28 rotates too much, causing the moving rod 31 to drive the limit plate 32 to move too far, thereby avoiding the limit plate 32 from clamping the defoaming agent barrel too tightly. At the same time, since the second gear 27 is fixed, when the second gear 27 is engaged with the second tooth block 29, the turntable 28 cannot rotate by itself, thereby achieving a stable limiting effect.
