Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive viscosity testing equipment, and particularly relates to an adhesive viscosity testing equipment. Background Art

[0002] Adhesive tack testing equipment is specialized equipment used to evaluate the tack properties of adhesives under various conditions. Using a range of testing methods and techniques, these devices can quantify the initial tack and sustained tack of adhesives, as well as other physical performance indicators related to tack. Initial tack refers to the initial adhesion strength of objects when they first come into contact. However, traditional devices may lack the ability to display the adhesive's adhesion strength in real time and cannot provide instant test data, making it difficult for testers to intuitively understand changes in adhesive performance. Traditional devices may also be unable to conduct continuous or repeated tests, requiring new preparation and setup for each test, resulting in low test efficiency and a lack of continuous performance data. Traditional devices can also be complex to operate, requiring specialized skills and significant time for pre-test preparation and post-test data analysis.

[0027] In this embodiment: Adhesive tack testing equipment is a specialized device used to evaluate the tack properties of adhesives under different conditions. These devices can quantify the initial tack and sustained tack of adhesives, as well as other physical performance indicators related to tack, through a series of testing methods and techniques. Initial tack refers to the adhesion strength when objects first come into contact, that is, the initial adhesion. However, traditional devices may lack the function of displaying the adhesive adhesion strength in real time and cannot provide test data immediately, resulting in the tester being unable to intuitively understand the performance changes of the adhesive. Traditional devices may not be able to perform continuous or repeated tests, and each test requires re-preparation and setup, resulting in low test efficiency and the inability to obtain continuous performance data. Traditional devices may be complex to operate, requiring professional skills and a lot of time for pre-test preparation and post-test data analysis. To solve this technical problem, test component 2 is added on this basis.

[0028] More specifically:

[0029] like Figures 1 to 6 As shown:

[0030] Combined with the above content: the test assembly 2 includes a motor 21, a fixed block 22 and a rotating disk 23. The motor 21 is installed on the outer side of the end of the mounting frame 1. The fixed block 22 is fixedly connected to the outer side of the main shaft of the motor 21. The inner side of the end of the fixed block 22 is slidably connected to the rotating disk 23. The inner side of the end of the rotating disk 23 is provided with a sliding groove 24. The inner side of the end of the mounting frame 1 is slidably connected to the test rod 26. The outer side of one end of the test rod 26 is fixedly connected to the sliding column 25. The outer side of the other end of the test rod 26 is fixedly connected to the test sleeve 27. The inner side of the end of the fixed block 22 rotates It is connected to a threaded rod 28, and the outer side of the end of the rotating disk 23 is fixedly connected to a limiting block 29. The inner side of the end of the limiting block 29 is threadedly connected to the outer side of the end of the threaded rod 28. The limiting block 29 is slidingly connected to the inner side of the end of the fixed block 22. The inner side of the end of the test sleeve 27 is slidingly connected to a bonding rod 210. The two ends of the spring 211 are respectively fixedly connected to the inner side of the end of the test sleeve 27 and the outer side of one end of the bonding rod 210. A scale ruler 212 is provided on the outer side of the end of the bonding rod 210, and a support leg 213 is fixedly connected to the outer side of the bottom end of the mounting frame 1.

[0031] In this embodiment, when the user uses the device, the user can install the adhesive to be tested on the upper surface of the test sticky block 214. At this time, the user can start the motor 21, and the motor 21 drives the fixed block 22 on the outer side of its main shaft to rotate. During the rotation of the fixed block 22, the rotating disk 23 is driven to rotate through the limit block 29. When the rotating disk 23 rotates, the sliding groove 24 opened at the end of the rotating disk 23 forces the sliding column 25 to move inside its track, and then the test rod 26 is driven to reciprocate in the vertical direction through the sliding column 25. The position of the limit block 29 on the inner side of the end of the fixed block 22 can be adjusted by rotating the threaded rod 28, thereby adjusting the rotation The amplitude of the rotation of the disk 23, thereby increasing the amplitude of the eccentric rotation of the rotating disk 23, can increase the amplitude of the vertical movement of the test rod 26. During the vertical reciprocating motion of the test rod 26, the test sleeve 27 at the end of the test rod 26 will be driven to move synchronously. The inner side of the end of the test sleeve 27 is slidably connected to the adhesive rod 210. At the same time, during the sliding process of the adhesive rod 210, the outer side of the end of the adhesive rod 210 will contact the adhesive on the surface of the test sticky block 214, and then the adhesive will generate adhesion to the end of the adhesive rod 210, and will pull the spring 211 through the adhesive rod 210 and store elastic potential energy. At this time, the user can see the scale 211 on the outer side of the end of the adhesive rod 210. 12 to observe the adhesion strength of the adhesive, the test rod 26 and the test sleeve 27 on the outer side of its end are driven to move vertically upward by the rotating disk 23. At this time, the outer side of the end of the adhesion rod 210 is separated from the surface of the adhesive. The adhesive can be tested by this reciprocating motion. The test sleeve 27 on the end of the test rod 26 can be driven to move back and forth in the vertical direction by the rotating disk 23 and the test rod 26. The scale 212 on the surface of the adhesion rod 210 allows the user to observe the adhesion strength of the adhesive in real time. This instant feedback can greatly improve the efficiency and accuracy of the test, because the operator does not need to wait for the test to be completed before analyzing the results. The reciprocating test sleeve 27 It can ensure that each test is carried out under the same conditions, thereby improving the repeatability of the test, which is very critical for comparing the performance of different adhesives or evaluating the performance of the same adhesive under different conditions. Combined with the design of the spring 211, the adhesion strength of the adhesive can be quantified. The elastic coefficient of the spring 211 and the scale 212 of the adhesion rod 210 are combined to accurately measure and record the deformation and recovery force of the adhesive under force, thereby accurately evaluating its viscosity. Since the testing process is automated, a large amount of test data can be collected. By analyzing these data, the formulation or production process of the adhesive can be further optimized to improve its performance and quality.

[0032] Going further:

[0033] In an optional embodiment, a test sticky block 214 is detachably connected to the inner side of the end of the mounting frame 1 .

[0034] In this embodiment: In this device, the adhesive of the adhesive sample can be quickly replaced through the detachable test sticky block 214, and the viscosity testing equipment will significantly improve testing efficiency and flexibility. The rapid replacement of the test sticky block 214 means that researchers and testers can easily evaluate the performance of different adhesives without spending a lot of time on equipment adjustment or preparation. This not only shortens the testing cycle, but also allows for more extensive product comparisons and more in-depth performance analysis. In addition, the ability to quickly replace the test sticky block 214 also makes the equipment easier to adapt to changing market demands and product development cycles, enhancing the practicality and economic value of the equipment.

[0035] Going further:

[0036] In an optional embodiment, a suction cup 215 is fixedly connected to the outer side of the end of the support leg 213 .

[0037] In this embodiment: multiple suction cups 215 are installed on the lower surface of the support legs 213 of the adhesive viscosity testing equipment, which will greatly enhance the stability and safety of the equipment during operation. These suction cups 215 can provide strong adsorption force to ensure that the equipment remains stable during the test and reduce the risk of displacement or tipping due to vibration or external force. At the same time, the design of the suction cups 215 also enables the equipment to be stably placed on work surfaces of different materials, thereby improving the adaptability and versatility of the equipment. Such a design not only ensures the accuracy and reliability of the test, but also provides users with a more convenient and safe operating experience.

[0038] Working principle: When using the device, the user can install the adhesive to be tested on the upper surface of the test adhesive block 214. At this time, the user can start the motor 21, and the motor 21 drives the fixed block 22 on the outside of its main shaft to rotate. During the rotation of the fixed block 22, the rotating disk 23 is driven to rotate through the limit block 29. When the rotating disk 23 rotates, the sliding groove 24 opened at the end of the rotating disk 23 forces the sliding column 25 to move inside its track, and then drives the test rod 26 to reciprocate in the vertical direction through the sliding column 25. The position of the limit block 29 on the inner side of the end of the fixed block 22 can be adjusted by rotating the threaded rod 28, and then the rotation amplitude of the rotating disk 23 can be adjusted, so that the test amplitude can be increased by increasing the eccentric rotation amplitude of the rotating disk 23. The amplitude of the movement of the test rod 26 in the vertical direction, the vertical reciprocating movement of the test rod 26 will drive the test sleeve 27 at the end of the test rod 26 to move synchronously, and the inner side of the end of the test sleeve 27 is slidably connected to the adhesive rod 210. At the same time, during the sliding process of the adhesive rod 210, the outer side of the end of the adhesive rod 210 will contact the adhesive on the surface of the test sticky block 214, and then the adhesive will generate adhesion to the end of the adhesive rod 210, and the spring 211 will be pulled by the adhesive rod 210 to store elastic potential energy. At this time, the user can observe the adhesion strength of the adhesive through the scale ruler 212 on the outer side of the end of the adhesive rod 210, and the test rod 26 and the test sleeve 27 on the outer side of its end are driven to move vertically upward by the rotating disk 23. At this time, the outer side of the end of the adhesive rod 210 is pulled from the adhesive The surface of the adhesive is detached, and the adhesive can be tested by this reciprocating motion. The rotating disk 23 and the test rod 26 can drive the test sleeve 27 at the end of the test rod 26 to move back and forth in the vertical direction. The scale 212 on the surface of the adhesion rod 210 allows the user to observe the strength of the adhesive adhesion in real time. This instant feedback can greatly improve the efficiency and accuracy of the test, because the operator does not need to wait for the test to be completed before analyzing the results. The reciprocating test sleeve 27 can ensure that each test is carried out under the same conditions, thereby improving the repeatability of the test, which is very important for comparing the performance of different adhesives or evaluating the performance of the same adhesive under different conditions. Combined with the design of the spring 211, the adhesion strength of the adhesive can be quantified. The elastic modulus of 11 and the scale 212 of the adhesive rod 210 are combined to accurately measure and record the deformation and restoring force of the adhesive under stress, thereby accurately evaluating its viscosity. Since the testing process is automated, a large amount of test data can be collected. By analyzing these data, the formulation or production process of the adhesive can be further optimized to improve its performance and quality. In this device, the adhesive of the adhesive sample can be quickly replaced through the detachable test sticky block 214. The viscosity testing equipment will significantly improve the testing efficiency and flexibility. The rapid replacement of the test sticky block 214 means that researchers and testers can easily evaluate the performance of different adhesives without spending a lot of time on equipment adjustment or preparation, which not only shortens the testing cycle,It also allows for more extensive product comparisons and more in-depth performance analysis. Furthermore, the ability to quickly replace test blocks 214 makes the device more adaptable to changing market demands and product development cycles, enhancing its practicality and economic value. Installing multiple suction cups 215 on the underside of the adhesive tack tester's support legs 213 significantly enhances the device's stability and safety during operation. These suction cups 215 provide strong adsorption force, ensuring the device remains stable during testing and reducing the risk of displacement or tipping due to vibration or external forces. Furthermore, the design of the suction cups 215 allows the device to be stably placed on work surfaces made of various materials, improving its adaptability and versatility.
