Description

Technical Field

[0001] This invention relates to the field of viscosity measurement technology, specifically to a viscosity measurement and protection device for the research and development of film-forming materials. Background Technology

[0002] In the field of materials science and engineering, the development of film-forming materials is an important research direction, widely used in electronics, medical, food packaging, coatings, and automotive protection industries. During the preparation of these materials, viscosity is one of the key indicators for evaluating their performance, stability, and processability. Viscosity, as a fundamental physical property of fluids, reflects the magnitude of the internal frictional force between molecules when a fluid is subjected to external forces, directly affecting the material's flowability, coating uniformity, and the quality of the final product. However, viscosity measurement often faces several challenges in the development of film-forming materials. During the development of film-forming materials, viscosity testing is required, necessitating the placement of a container filled with coating material in a viscosity measuring device. The test instrument is positioned below the container, with the rotor inserted into the vessel. The rotor is then driven to rotate within the coating, and the viscosity of the coating is measured using the testing unit. A viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that represents the internal friction of a fluid during flow; it is the fluid's ability to resist deformation and is an important indicator for identifying certain finished or semi-finished products. Viscosity varies with different fluids and temperature. There are three main types: capillary viscometers, rotational viscometers, and falling ball viscometers. The rotor of the viscosity control instrument needs to be protected during use to avoid affecting the measurement accuracy of the viscosity control instrument. The rotor of the viscosity control instrument should also be cleaned after use.

[0003] In the prior art, such as the ink rotational viscosity tester disclosed in CN213022743U, a base is provided, a support rod is provided on the base, and an instrument body is vertically mounted on the support rod. A motor is provided at the bottom of the instrument body, and a rotor is provided at the bottom of the output shaft of the motor. A protective frame is vertically mounted at the lower end of the motor, and an annular guardrail is provided on the protective frame, which is fitted over the outside of the rotor. The aforementioned ink rotational viscosity tester, with its annular guardrail on the protective frame, provides further protection for the rotor, resulting in better protection and making the rotor less susceptible to damage.

[0004] However, in actual use, the protective frame is connected to the motor by bolts. Although it plays a role in protecting the rotor, the protective frame is complicated to install and requires frequent disassembly and assembly for cleaning, which can cause the threads to fail. This can lead to the protective frame shaking, increase the liquid backflow effect, and make it difficult to achieve effective protection of the rotor.

[0005] Therefore, this invention proposes a viscosity measurement and protection device for film-forming material research and development to solve the problem of inconvenient disassembly and assembly of existing rotor protection frames, resulting in poor rotor protection effect. It can realize convenient disassembly and assembly of rotor protection frames while reducing vibration caused by rotor speed and maintaining stable detection of film-forming material viscosity.

[0012] Preferably, both ends of the abutting bending rod are fixedly connected to the inner surface of the deformation groove, and the two ends of the abutting bending rod are respectively slidably fitted with energy-storing elastic wires.

This also reduces vibration during high-speed rotor rotation, facilitates the disassembly and assembly of the protective frame, and improves the accuracy of coating viscosity test data.

[0033] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 1-13, the present invention provides a technical solution: a viscosity measurement protection device for the research and development of film-forming materials, including a base 1. A support frame 11 is fixedly installed at the upper end of the base 1. A viscosity tester body 2 is movably installed on the outer surface of the support frame 11. A pivot cup 21 is installed at the lower end of the viscosity tester body 2. A rotor 22 is detachably installed at the lower end of the pivot cup 21. A protective frame 3 is arranged outside the rotor 22. A ring seat 4 is fixedly installed at the upper end of the protective frame 3. An annular elastic sleeve plate 5 is fixedly connected to the upper end of the ring seat 4. A clamping mechanism 6 is arranged inside the annular elastic sleeve plate 5. A bottom connection seat 7 is movably installed outside the annular elastic sleeve plate 5. The bottom connection seat 7 is fixedly installed at the lower end of the viscosity tester body 2. Side grooves 71 are formed on the inner walls of both sides of the bottom connection seat 7. A plug-in component 72 is arranged inside the side grooves 71. An avoidance ring groove 8 is formed on the lower inner wall of the side grooves 71. A clamping ring plate 9 is movably installed inside the avoidance ring groove 8; by connecting the annular elastic sleeve plate 5 to the upper end of the protective frame 3 and evenly arranging the clamping mechanism 6 on the inner ring surface of the annular elastic sleeve plate 5, when the annular elastic sleeve plate 5 is sleeved outside the pivot cup 21, the whole plug-in component 72 is moved, so that the clamping ring plate 9 is released from the restriction and wraps around the outside of the lower annular elastic sleeve plate 5. While the annular elastic sleeve plate 5 undergoes elastic deformation, the clamping mechanism 6 is compressed, and a certain reverse elastic force realizes the clamping of the pivot cup 21, and can weaken the jitter of the rotor 22 during high-speed rotation, which is helpful for the disassembly and installation of the protective frame 3, with convenient operation, and at the same time promotes the accuracy of the coating viscosity test data; and through the installation of the protective frame 3, the rotor 22 can be protected to avoid the collision of the cup wall against the rotor 22 during measurement; on the other hand, as the reduction of the echo effect, when the sample coating viscosity is sparse and the rotation speed is relatively high, the rotor 22 rotates relatively fast, and some echo effects will occur in the liquid. The ripples of the rotor 22 rotating will return to the cup wall, and the cup wall will then rebound to the rotor, generating a certain force, resulting in inaccurate measurement data. However, through the protective frame 3, the echo can be protected to ensure more accurate measurement data.

[0036] Embodiment 2

[0037] Refer to the appendix Figure 1-13 , on the basis of Embodiment 1, in order to achieve dust-proof protection for the bottom connection seat 7 or the lower pivot cup 21, a dust-proof component is added in this embodiment: a dust-proof component is fixedly added to the lower outer ring surface of the clamping ring plate 9. The dust-proof component includes a socket ring plate 10. The socket ring plate

[0038] A mounting ring plate 10 is added to the outer ring surface of the clamping ring plate 9, and a folding shrink cover 103 is connected to the inner cavity of the receiving groove 102. The user pinches the rubber ring 104 and stretches the folding shrink cover 103. The rubber ring 104 can be stored in the U-shaped ring groove 101. When the paint viscosity test is not performed and the protective frame 3 is not installed, the rubber ring 104 is pulled upward to cover the bottom connecting seat 7 for dust protection. When the pivot cup 21 needs to be covered, the rubber ring 104 is pinched with fingers in the same way and pulled downward to stretch the folding shrink cover 103. The elastic effect of the rubber ring 104 covers the pivot cup 21 and its lower end. This achieves multi-functional and multi-directional dust protection, ensuring the protection of the device when it is not in use and preventing dust accumulation that could affect the accuracy of viscosity test data.

[0039] Example 3

[0040] See attached document Figure 1-13 Based on Embodiment 2, to enhance the buffering and stability of the connection between the pivot cup 21 and the annular elastic sleeve 5: the annular elastic sleeve 5 is an overall annular plate structure, and deformation grooves 51 are formed on the inner wall of the annular elastic sleeve 5. Six sets of deformation grooves 51 are arranged in an equidistant array about the central axis of the annular elastic sleeve 5; the clamping mechanism 6 includes a central block 61 and side elastic components 62. The central block 61 is fixedly installed on the inner ring surface of the annular elastic sleeve 5, and an arc-shaped back plate 611 is fixedly installed on the inner surface of the central block 61. Clamping plates 613 are fixedly connected to both ends of the arc-shaped back plate 611, and the inner ring surface of the clamping plate 613 is movably connected to the outer surface of the pivot cup 21; a curved elastic pad 612 is provided on the inner ring surface of the arc-shaped back plate 611, and both ends of the arc-shaped back plate 611 are fixedly connected to the inner surface of the arc-shaped back plate 611. An arc-shaped groove 6121 is formed on the inner wall of the elastic pad 612. The arc-shaped groove 6121 has a semi-annular hollow groove structure. The side elastic component 62 includes a protrusion 621 and an abutting bent rod 624. The protrusion 621 is fixedly installed on the outer surface of the arc-shaped back plate 611. The two outer surfaces of the protrusion 621 are hinged to hinge rods 622. The other end of the hinge rod 622 is rotatably connected to a sliding collar 623. The sliding collar 623 has a circular tube structure. The inner surface of the sliding collar 623 is movably connected to the outer surface of the abutting bent rod 624. The two ends of the abutting bent rod 624 are fixedly connected to the inner surface of the deformation groove 51. The two ends of the abutting bent rod 624 are respectively slidably fitted with a storage spring wire 625. One end of the storage spring wire 625 is fixedly connected to the outer surface of the sliding collar 623, and the other end of the storage spring wire 625 is fixedly connected to the inner surface of the annular elastic sleeve plate 5.

[0041] The lower end of the annular elastic sleeve 5 is connected to the ring seat 4 and fixed to the upper end of the protective frame 3. Six sets of deformation grooves 51 are evenly opened on the inner wall of the annular elastic sleeve 5 to reserve a certain space for the elastic deformation of the annular elastic sleeve 5. Clamping mechanisms 6 are evenly arranged on the inner annular surface of the annular elastic sleeve 5. When the annular elastic sleeve 5 is initially fitted onto the outside of the pivot cup 21, there is a certain distance between the clamping mechanism 6 and the pivot cup 21. Subsequently, when the annular elastic sleeve 5 is pushed by the covering force, the arc-shaped back plate 611 on the inner side of the annular elastic sleeve 5 pushes towards the clamping plate 613. Both the arc-shaped back plate 611 and the clamping plate 613 undergo elastic deformation. At the same time, the curved elastic pad 612 connected between the arc-shaped back plate 611 and the clamping plate 613 also deforms and gradually contacts the back end of the clamping plate 613. The contact provides a supporting force to the clamping plate 613. The reason for the staggered arc grooves 6121 on the curved elastic pad 612 is to increase the stress of the curved elastic pad 612 bending deformation. Subsequently, the side elastic components 62 at both ends of the arc back plate 611 are pushed in the opposite direction by the stored elastic energy. At this time, the abutting bent rod 624 bends under the influence of external force. The angle of the hinge rod 622 changes, so that the sliding collar 623 moves on the surface of the abutting bent rod 624. The stored elastic wire 625 is compressed. In this way, through the overall setting of the clamping mechanism 6, on the one hand, the clamping force between the clamping ring plates 9 is enhanced, and on the other hand, the vibration of the rotor 22 driven by the pivot cup 21 is weakened, avoiding the shaking of the protective frame 3 and the rotor 22, further enhancing the stability of the film-forming material viscosity detection and the accuracy of the test data.

[0042] Example 4

[0043] See attached document Figure 1-13 Based on Embodiment 3, in order to realize the installation of the clamping ring plate 9: a reserved groove 91 is provided on the upper inner wall of the clamping ring plate 9, and the reserved groove 91 is set in six groups. The bottom surface of the inner cavity of each of the six reserved grooves 91 is fixedly connected to a curved metal spring piece 911, and the upper end of the curved metal spring piece 911 is fixedly connected to the top surface of the inner cavity of the clearance ring groove 8; an inner inclined surface 93 is provided on the lower inner ring surface of the clamping ring plate 9, and the outer surface of the inner inclined surface 93 is movably connected to the outer surface of the annular elastic sleeve plate 5.

[0044] A pre-reserved groove 91 is evenly opened on the upper inner wall of the clamping ring plate 9, connecting the correspondingly distributed curved metal springs 911. One end of the curved metal spring 911 is connected to the top surface of the inner cavity of the clearance ring groove 8. When the clamping ring plate 9 is in the locked state, the curved metal spring 911 is always in the compressed and stored state. When the clamping ring plate 9 is in the unlocked state, the curved metal spring 911 pushes the clamping ring plate 9 downward, and the inner inclined surface 93 opened on the lower inner ring surface of the clamping ring plate 9 covers and squeezes the outside of the annular elastic sleeve plate 5.

[0045] Example 5

[0046] See attached document Figure 1-13 Based on Embodiment 4, in order to achieve rapid locking and releasing of the clamping ring plate 9:

[0047] A slot 92 is provided on the outer ring surface of the clamping ring plate 9. A plug-in assembly 72 is provided on the inner side of the slot 92. The plug-in assembly 72 includes a fixing block 721 and a locking block 725. The outer surface of the locking block 725 is movably plugged into the inner wall of the slot 92. The fixing block 721 is fixedly installed on the inner surface of the side groove 71. A guide rod 723 is slidably connected to the inner surface of the fixing block 721. One end of the guide rod 723 is fixedly connected to the outer surface of the locking block 725. A push plate 722 is fixedly installed on the end of the guide rod 723 away from the locking block 725. An abutment spring 724 is fixedly connected to the outer surface of the locking block 725. The other end of the abutment spring 724 is fixedly connected to the inner surface of the fixing block 721. The abutment spring 724 is slidably sleeved on the outside of the guide rod 723.

[0048] A slot 92 is formed on the outer ring surface of the clamping ring plate 9. When the clamping ring plate 9 is in the locked state, the inner wall of the slot 92 is engaged with the outer side of the locking block 725 for limiting insertion, as shown in the attached diagram. Figure 3 and 4 As shown, at this time, the locking block 725 is inserted into the slot 92, locking and limiting the entire clamping ring plate 9; when the clamping ring plate 9 is released from its limiting position, the locking block 725 disengages from the slot 92, as shown in the attached diagram. Figure 7 As shown; in specific operation, after the operator places the annular elastic sleeve 5 and the protective frame 3 onto the outside of the pivot cup 21, the operator holds the ring seat 4 with one hand, aligning the inner side of the annular elastic sleeve 5 with the outer position of the pivot cup 21, while the thumb and forefinger of the other hand extend outwards, aligning the two fingers with the oppositely distributed push plates 722 and pushing them outwards. Subsequently, the guide rod 723 drives the locking block 725 to move outwards, at which point the slot 92 releases the restriction of the locking block 725, holding the annular plate 9 tightly in the curved metal... The elastic force of the spring 911 clamps and covers the outer part of the lower annular elastic sleeve 5, causing the upper part of the annular elastic sleeve 5 to retract inward, ensuring a tight connection with the pivot cup 21. At this time, the operator can remove the fingers from the push plate 722, and then the locking block 725 is reset by the elastic force of the abutment spring 724. At this time, the locking block 725 abuts against the upper end of the clamping ring plate 9, thus achieving further limiting and locking of the clamping ring plate 9 and preventing the clamping ring plate 9 from retracting upward due to external force.

[0049] When the entire protective frame 3 needs to be disassembled, the operator only needs to repeat the above operation. Push the push plate 722 outward with two fingers of one hand. At this time, the upper end of the clamping ring plate 9 is released from restriction. The operator holds the ring seat 4 with the other hand and gently pulls the annular elastic sleeve 5 out from between the clamping ring plate 9 and the protective frame 3. Then, push the lower end of the clamping ring plate 9 to compress the curved metal spring 911 until the top of the clamping ring plate 9 contacts the top surface of the inner cavity of the avoidance ring groove 8. Then, release the two fingers. At this time, the locking plug 725 is restored by the elastic stored force of the abutment spring 724. In this way, the locking plug 725 locks the entire clamping ring plate 9.

[0050] The working principle and usage process of this invention are as follows: In actual operation, firstly, the operator places the annular elastic sleeve 5 and the protective frame 3 onto the outside of the pivot cup 21. At this time, the operator holds the ring seat 4 with one hand, aligning the inner side of the annular elastic sleeve 5 with the outer position of the pivot cup 21. The thumb and forefinger of the other hand extend outwards, aligning the two fingers with the oppositely distributed push plates 722 and pushing them outwards. Subsequently, the guide rod 723 drives the locking block 725 to move outwards. At this time, the slot 92 releases the restriction of the locking block 725. The clamping ring plate 9, under the elastic storage force of the curved metal spring 911, covers and clamps the outer side of the annular elastic sleeve 5 below. The upper part of the annular elastic sleeve 5 retracts inwards to ensure contact with the outer side of the pivot cup 21. The pivot cups 21 are securely connected; at this time, the operator can remove their fingers from the expanding push plate 722, and then the locking block 725 is reset by the elastic force stored in the abutment spring 724. At this time, the locking block 725 abuts against the upper end of the clamping ring plate 9, thus achieving further limiting and locking of the clamping ring plate 9 and preventing the clamping ring plate 9 from retracting upward under the influence of external force; then, when the outer side of the annular elastic sleeve plate 5 is pushed by the covering force, the arc-shaped back plate 611 on the inner side of the annular elastic sleeve plate 5 pushes against the clamping plate 613. Both the arc-shaped back plate 611 and the clamping plate 613 undergo elastic deformation, and at this time, the curved elastic gasket 612 connected between the arc-shaped back plate 611 and the clamping plate 613 also deforms. Gradually contacting the back end of the clamping plate 613, it provides a supporting force to the clamping plate 613. The reason for the staggered opening of multiple sets of arc-shaped grooves 6121 on the curved elastic pad 612 is to increase the stress of the curved elastic pad 612 bending deformation. Subsequently, the side elastic components 62 at both ends of the arc-shaped back plate 611 are subjected to the reverse push of the elastic energy storage. At this time, the abutting bent rod 624 bends under the influence of external force, and the angle of the hinge rod 622 changes, causing the sliding collar 623 to move on the surface of the abutting bent rod 624. The energy storage spring wire 625 is compressed. In this way, through the overall setting of the clamping mechanism 6, on the one hand, the clamping force between the clamping ring plates 9 is enhanced, and on the other hand, the rotation of the rotor 22 driven by the pivot cup 21 is weakened. The vibration under high-speed rotation prevents the protective frame 3 and rotor 22 from shaking. Finally, after the protective frame 3 is disassembled, the rubber ring 104 is pinched by hand and the folding shrink cover 103 is stretched. When the bottom connecting seat 7 is dustproofed, the rubber ring 104 is pulled upward and the outside of the bottom connecting seat 7 is covered. When the pivot cup 21 needs to be covered, the rubber ring 104 is pinched by hand in the same way and stretched downward, so that the folding shrink cover 103 is stretched. The elastic effect of the rubber ring 104 covers the pivot cup 21 and its lower end. In this way, multi-functional and multi-directional dustproof protection is achieved, ensuring the protection of the device when it is not in use and preventing dust accumulation, which would affect the accuracy of viscosity detection data.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
