Description

Technical Field

[0001] The invention relates to the technical field of viscosity measurement, in particular to a viscosity measurement protection device for film-forming material research and development. Background Art

[0002] In the field of materials science and engineering, the research and development of film-forming materials is an important research direction. They are widely used in many industries such as electronics, medical treatment, food packaging, coatings and automobile protection. During the preparation process of these materials, their viscosity characteristics are one of the key indicators for evaluating their performance, stability and processability. Viscosity, as a basic physical property of fluid substances, reflects the magnitude of the internal friction between molecules when the fluid is subjected to external forces. It has a direct impact on the fluidity of the material, coating uniformity and the quality of the final product. However, in the research and development of film-forming materials, viscosity measurement often faces many challenges. During the research and development of film-forming materials, viscosity testing is required. The container containing the coating needs to be placed in the viscosity measuring vessel. The viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that indicates the internal friction of the fluid when it flows. It is the ability of the fluid to resist deformation and is an important indicator for identifying certain finished or semi-finished products. The viscosity varies with different fluids and changes with temperature. There are mainly three types: capillary viscometer, rotational viscometer and falling ball viscometer. The rotor of the viscosity controller needs to be protected when in use to avoid affecting the measurement accuracy of the viscosity controller. The rotor of the viscosity controller should also be cleaned after use.

The above document uses an ink rotation viscosity tester, and an annular guardrail is provided on the protective frame. The annular guardrail can further protect the rotor, and the protection effect is better, so that the rotor is less susceptible to damage.

[0004] However, in actual use, the protection frame is connected to the motor by bolts. Although it plays a protective role in protecting the rotor, the protection frame is complicated to install and needs to be frequently disassembled and assembled during disassembly and cleaning, which causes thread failure, resulting in shaking of the protection frame, increasing the echo effect of the liquid, and making it difficult to achieve effective protection of the rotor.

DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0021] Embodiment 1 See also Figure 1-13 The present invention provides a technical solution: a viscosity measurement protection device for film-forming material research and development, comprising a base 1, a support frame 11 is fixedly installed on 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 on the lower end of the viscosity tester body 2, a rotor 22 is detachably installed on the lower end of the pivot cup 21, a protection frame 3 is arranged outside the rotor 22, a ring seat 4 is fixedly installed on the upper end of the protection frame 3, an annular elastic sleeve plate 5 is fixedly connected to the upper end of the ring seat 4, and the ring A clamping mechanism 6 is provided on the inner side of the annular elastic sleeve 5, and a bottom connecting seat 7 is movably installed on the outside of the annular elastic sleeve 5. The bottom connecting seat 7 is fixedly installed on the lower end of the viscosity tester body 2. Side grooves 71 are provided on the inner walls of both sides of the bottom connecting seat 7. A plug-in assembly 72 is provided inside the side groove 71. An avoidance ring groove 8 is provided on the inner wall of the lower end of the side groove 71. A clamping ring plate 9 is movably installed on the inner side of the avoidance ring groove 8. By connecting the annular elastic sleeve 5 to the upper end of the protective frame 3, the inner side of the annular elastic sleeve 5 is The clamping mechanism 6 is evenly arranged on the surface of the ring. When the annular elastic sleeve 5 is sleeved to the outside of the pivot cup 21, the plug-in assembly 72 is moved as a whole, so that the clamping ring plate 9 is released from the restriction and covers the outside of the annular elastic sleeve 5 below. When the annular elastic sleeve 5 realizes 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 shaking of the rotor 22 when it rotates at high speed, which is helpful for the disassembly and assembly of the protective frame 3, and the operation is convenient, and at the same time, it promotes the accuracy of the paint viscosity test data; and through the installation of the protective frame 3, the rotor 22 can be protected to avoid the cup wall from colliding with the rotor 22 during measurement; on the other hand, as a reduction of the echo effect, when the viscosity of the sample paint is sparse and the rotation speed is relatively large, the rotor 22 rotates faster, and some echo effects will be generated in the liquid. The ripples of the rotation of the rotor 22 will return to the cup wall, and the cup wall will rebound to the rotor, which will generate a certain force, resulting in inaccurate measurement, and the echo can be protected by the protective frame 3 to ensure more accurate measurement data.

[0022] Embodiment 2 See attached Figure 1-13, on the basis of the first embodiment, in order to achieve dust-proof protection for the bottom connecting 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 outer ring surface of the lower side of the clamping ring plate 9. The dust-proof component includes a socket ring plate 10. The socket ring plate 10 is fixedly installed on the outer surface of the clamping ring plate 9. A receiving groove 102 is formed on the upper surface of the socket ring plate 10. A folding and shrinking cover 103 is fixedly connected to the inner cavity bottom surface of the receiving groove 102. An rubber ring 104 is fixedly connected to the upper end of the folding and shrinking cover 103. A U-shaped ring groove 101 is fixedly added to the outer ring surface of the socket ring plate 10. The side view剖切 cross-section of the U-shaped ring groove 101 is in a "匚" shape structure. The inner surface of the U-shaped ring groove 101 is movably connected to the outer surface of the rubber ring 104; An installation socket ring plate 10 is added to the outer ring surface of the clamping ring plate 9, and a folding and shrinking cover 103 is connected to the inner cavity of the receiving groove 102. The user pinches the rubber ring 104 with the hand to stretch the folding and shrinking cover 103. Through the setting of the U-shaped ring groove 101, the rubber ring 104 can be received. When the viscosity of the paint is not tested and the protective frame 3 is not installed, when dust-proof protection is carried out on the bottom connecting seat 7, the rubber ring 104 is pulled up to cover the outside of the bottom connecting seat 7; when the pivot cup 21 needs to be covered, in the same way, the rubber ring 104 is pinched with the finger and pulled downwards, so that the folding and shrinking cover 103 is stretched, and the pivot cup 21 and the lower end are covered by relying on the elastic effect of the rubber ring 104. In this way, multi-functional and multi-directional dust-proof protection is achieved, ensuring the protection of the device when it is not in use and avoiding dust accumulation from affecting the accuracy of viscosity detection data.

[0023] Embodiment Three Refer to the appendix Figure 1-13On the basis of the second embodiment, in order to increase the buffering property and stability of the connection between the pivot cup 21 and the annular elastic sleeve 5: the annular elastic sleeve 5 is an annular plate-shaped structure as a whole, and a deformation groove 51 is provided on the inner wall of the annular elastic sleeve 5, and the deformation groove 51 is provided in six groups and is arranged in an array equidistantly about the central axis of the annular elastic sleeve 5; the clamping mechanism 6 includes a central block 61 and a side elastic component 62, the central block 61 is fixedly mounted on the inner ring surface of the annular elastic sleeve 5, and an arc-shaped back plate 611 is fixedly mounted on the inner surface of the central block 61, and clamping plates 613 are fixedly connected at 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 gasket 612 is provided on the inner ring surface of the arc-shaped back plate 611, and the two ends of the arc-shaped back plate 611 are fixedly connected to the inner surface of the arc-shaped back plate 611, and the curved elastic gasket 612 is provided on the inner ring surface of the arc-shaped back plate 611. An arc groove 6121 is provided on the inner wall of the deformable elastic gasket 612, and the arc groove 6121 is 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, and the outer surfaces of both sides of the protrusion 621 are hingedly installed with hinged rods 622, and the other end of the hinged rod 622 is rotatably connected with a sliding ring 623, and the sliding ring 623 is a circular tubular structure, and the inner surface of the sliding ring 623 is movably connected with 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, and the two ends of the abutting bent rod 624 are respectively slidably sleeved with a force storage elastic wire 625, one end of the force storage elastic wire 625 is fixedly connected to the outer surface of the sliding ring 623, and the other end of the force storage elastic wire 625 is fixedly connected to the inner surface of the annular elastic sleeve plate 5; The lower end of the annular elastic sleeve 5 is connected to the annular seat 4 and fixed to the upper end of the protective frame 3. Six groups of deformation grooves 51 are evenly arranged 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, and the clamping mechanism 6 is evenly arranged on the inner ring surface of the annular elastic sleeve 5. When the annular elastic sleeve 5 is sleeved on the outside of the pivot cup 21 in the initial state, there is a certain distance between the clamping mechanism 6 as a whole and the pivot cup 21. Subsequently, when the outside of 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 is pushed toward the clamping plate 613, and the arc-shaped back plate 611 and the clamping plate 613 both produce elastic deformation, and at this time, the curved elastic gasket 612 connected between the arc-shaped back plate 611 and the clamping plate 613 is also deformed, and gradually connects with the back end of the clamping plate 613 The contact can provide a supporting force for the clamping plate 613. The reason why multiple groups of arc grooves 6121 are staggered on the curved elastic gasket 612 is to increase the stress of the bending deformation of the curved elastic gasket 612; then, the side elastic components 62 at both ends of the arc back plate 611 are pushed in the opposite direction by the elastic energy storage. At this time, the abutting bent rod 624 is bent by the influence of the external force, and the angle of the hinge rod 622 changes so that the sliding ring 623 moves on the surface of the abutting bent rod 624, and the energy storage 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 plate 9 is enhanced, and on the other hand, the vibration of the rotor 22 driven by the pivot cup 21 under high-speed rotation is weakened, thereby avoiding the shaking of the protective frame 3 and the rotor 22, and further enhancing the stability of the viscosity detection of the film-forming material and the accuracy of the test data.

[0024] Embodiment 4 See attached Figure 1-13 On the basis of the third embodiment, in order to realize the installation of the clamping ring plate 9: a reserved groove 91 is provided on the inner wall of the upper end of the clamping ring plate 9, and the reserved grooves 91 are arranged in six groups. The inner cavity bottom surfaces of the six groups of reserved grooves 91 are fixedly connected with curved metal springs 911, and the upper ends of the curved metal springs 911 are fixedly connected with the inner cavity top surface of the avoidance ring groove 8; the lower inner ring surface of the clamping ring plate 9 is provided with an inner bevel 93, and the outer surface of the inner bevel 93 is movably connected with the outer surface of the annular elastic sleeve plate 5; Reserved grooves 91 are evenly opened on the upper inner wall of the clamping ring plate 9, and the correspondingly distributed curved metal springs 911 are connected, and one end of the curved metal springs 911 is connected to the top surface of the inner cavity of the avoidance ring groove 8. When the clamping ring plate 9 is in a locked state, the curved metal springs 911 are always in a compressed and force-storing state; and when the clamping ring plate 9 is in an unlocked state, the curved metal springs 911 push the clamping ring plate 9 downward, and the inner bevel 93 opened on the inner ring surface of the lower side of the clamping ring plate 9 covers and squeezes the outside of the annular elastic sleeve plate 5.

[0025] Embodiment 5 See attached Figure 1-13 , based on the fourth embodiment, in order to realize the rapid locking and releasing of the clamping ring plate 9: A slot 92 is provided on the outer ring surface of the clamping ring plate 9, and 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 plug-in block 725. The outer surface of the locking plug-in block 725 is movably plugged with the inner wall of the slot 92. The fixing block 721 is fixedly installed on the inner surface of the side groove 71. The inner surface of the fixing block 721 is slidably connected with a guide rod 723, and one end of the guide rod 723 is fixedly connected with the outer surface of the locking plug-in block 725; a push plate 722 is fixedly installed on the end of the guide rod 723 away from the locking plug-in block 725, and an abutting spring 724 is fixedly connected to the outer surface of the locking plug-in block 725, and the other end of the abutting spring 724 is fixedly connected to the inner surface of the fixing block 721, and the abutting spring 724 is slidably sleeved on the outside of the guide rod 723; The outer ring surface of the clamping ring plate 9 is provided with a slot 92. When the clamping ring plate 9 is in a locked state, the inner wall of the slot 92 is limitedly plugged with the outer side of the locking plug block 725. Figure 3 and 4 As shown, the locking plug 725 is inserted into the slot 92 to lock the entire clamping ring plate 9; and when the clamping ring plate 9 is released from the limit, the locking plug 725 is separated from the slot 92, as shown in the attached Figure 7 As shown; in terms of specific operation, after the operator sets the annular elastic sleeve plate 5 and the protective frame 3 as a whole to the outside of the pivot cup 21, the operator holds the ring seat 4 with one hand to align the inner side of the annular elastic sleeve plate 5 with the outer position of the pivot cup 21, and the thumb and index finger of the other hand extend outward respectively, align the two fingers with the relatively distributed push plates 722 and push them outward, then the guide rod 723 drives the locking plug 725 to move outward, at this time the slot 92 releases the restriction of the locking plug 725, and the ring plate 9 is held tightly in the curved metal The elastic force storage force of the spring piece 911 covers and clamps the outer part of the annular elastic sleeve plate 5 below, and the upper part of the annular elastic sleeve plate 5 retracts inward to ensure a tight connection with the pivot cup 21; at this time, the operator can remove the finger of the expansion push plate 722, and then the locking plug block 725 is reset by the elastic force storage of the abutment spring 724. At this time, the locking plug block 725 abuts against the upper end of the clamping ring plate 9, thereby achieving further limit locking of the clamping ring plate 9 to prevent the clamping ring plate 9 from retracting upward under the influence of external force; When it is necessary to disassemble the protective frame 3 as a whole, the staff only needs to repeat the above operation, push the push plate 722 outward with two fingers of one hand, and then the upper end of the clamping ring plate 9 is released from the restriction. The operator holds the ring seat 4 as a whole with the other hand, and gently pulls the annular elastic sleeve plate 5 out from between the clamping ring plate 9 to place the protective frame 3. Then, the lower end of the clamping ring plate 9 is pushed to compress the curved metal spring sheet 911 until the top of the clamping ring plate 9 is pushed into contact with the top surface of the inner cavity of the avoidance ring groove 8. Then, the two fingers are released. At this time, the locking plug 725 is restored by the elastic stored force of the abutting spring 724, so that the locking plug 725 realizes the locking of the clamping ring plate 9 as a whole.

[0026] The working principle and use process of the present invention are as follows: in actual operation, first, the operator sets the annular elastic sleeve plate 5 and the protective frame 3 as a whole to the outside of the pivot cup 21. At this time, the operator holds the ring seat 4 with one hand to align the inner side of the annular elastic sleeve plate 5 with the outer position of the pivot cup 21, and the thumb and index finger of the other hand extend outward respectively, and the two fingers align with the relatively distributed push plates 722 and push them outward. Then, the guide rod 723 drives the locking plug 725 to move outward. At this time, the slot 92 releases the restriction of the locking plug 725, and the elastic storage force of the curved metal spring sheet 911 of the clamping ring plate 9 covers and clamps the outer side of the annular elastic sleeve plate 5 below, and the upper part of the annular elastic sleeve plate 5 retracts inward to ensure that it is in contact with the outer ring. When the locking cam 725 is in the state of being lifted up, the locking cam 725 will be in the state of being lifted up and locked to the locking cam 726, so that the locking cam 725 can be locked to the locking cam 726 by the effect of the spring 724. The spring 625 is compressed and the spring 626 is compressed to prevent the spring 626 from sliding onto the back of the clamping plate 613. The spring 626 is compressed to prevent the spring 626 from sliding onto the back of the clamping plate 613. The spring 626 is compressed to prevent the spring 626 from sliding onto the back of the clamping plate 613. The spring 626 is compressed to prevent the spring 626 from sliding onto the back of the clamping plate 613. The vibration under high-speed rotation avoids the shaking of the protective frame 3 and the rotor 22; finally, after the protective frame 3 is disassembled, pinch the rubber ring 104 with your hand to stretch the folding and shrinking cover 103, and when the bottom connecting seat 7 is protected from dust, pull the rubber ring 104 upward to cover the outside of the bottom connecting seat 7; and when the pivot cup 21 needs to be covered, pinch the rubber ring 104 with your fingers in the same way and stretch it downward to stretch the folding and shrinking cover 103, and rely on the elastic effect of the rubber ring 104 to cover the pivot cup 21 and the lower end, thereby achieving multi-functional and multi-directional dust protection, ensuring the protection of the device when not in use, avoiding dust accumulation and affecting the accuracy of the viscosity detection data.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
