Description

Technical Field

[0001] The utility model relates to the technical field of adhesive testing, in particular to an adhesive viscosity testing device. Background Art

[0002] Adhesive is a substance that can form a bond between two or more surfaces, firmly bonding two or more materials together to form a whole. It is used to replace traditional mechanical connection methods such as screws and welding to achieve a lighter and more beautiful design. It can also achieve connection when the connection surface is uneven, complex in shape or different in material.

[0003] After searching, a Chinese patent discloses an adhesive viscosity testing device (authorization announcement number CN220170842U) including a test structure, an angle adjustment mechanism, and a driving mechanism. The adhesive is applied to the test structure, the angle adjustment mechanism is bonded to the adhesive on the test structure, the driving mechanism is fixedly connected to the angle adjustment mechanism, and the angle adjustment mechanism can be driven to rotate in a first direction or a second direction. The rotation direction of the first direction is opposite to the rotation direction of the second direction to control the peeling angle when peeling the adhesive. Although the patented technology can apply the adhesive to the test structure, and then bond the angle adjustment mechanism to the adhesive on the test structure, the driving mechanism is fixedly connected to the angle adjustment mechanism, and the driving mechanism drives the angle adjustment mechanism to rotate in the first direction or the second direction to make the angle adjustment mechanism peel off from the adhesive. The peeling angle is determined so as to facilitate the test of the angle adjustment mechanism. The required force when peeling from the adhesive at different angles;

[0004] However, in the actual application of this patented technology, the above-mentioned adhesive viscosity testing equipment cannot provide buffering when detecting the tension of the adhesive. On the one hand, the lack of buffering will cause the force received by the adhesive during the test to be uneven or too sharp, which will affect the accuracy and repeatability of the test results. On the other hand, in the absence of buffering, the adhesive will suddenly break when subjected to excessive tension, rather than gradually failing, which will not fully reflect the performance of the adhesive in actual use.

[0005] In view of the above problems, we have launched an adhesive viscosity testing equipment. Summary of the invention

[0006] The utility model discloses an adhesive viscosity testing device, which aims to solve the technical problem that buffering cannot be performed when the tension of the adhesive is tested.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The top of the upper and lower plates are provided with a spring, and the top of the lower and lower plates are provided with a spring.

[0009] By setting up an operating table, a U-shaped plate, a sliding rod, an upper alignment plate, a lower alignment plate, a pressure plate and a test plate, the design realizes precise pressure and position control of the adhesive sample, ensures the consistency and repeatability of the test, and improves the accuracy and reliability of the test results.

[0011] By setting the connecting plate, the first connecting rod and the second connecting rod inside the U-shaped plate, precise movement control of the pressure plate and the lower alignment plate is achieved, providing a stable and adjustable operation method, making the force distribution during the test more uniform, and further improving the test accuracy.

[0012] In a preferred solution, a cylinder is fixedly connected to the top of the U-shaped plate, and an output end of the cylinder extends to the inside of the U-shaped plate and is fixedly connected to the top of the pressure plate.

[0013] By setting a cylinder fixed on the top of the U-shaped plate, the pressure plate is directly driven to apply or release pressure to the test sample.

[0014] In a preferred solution, both ends of the adjacent sides of the two test plates are fixedly connected with tension detectors.

[0015] By setting up two test plates equipped with tension detectors, the force conditions of the samples can be monitored and recorded in real time, and the data can be accurately measured and recorded.

[0016] In a preferred solution, a placement groove is provided on one side of the operating table, and a baffle is connected to one side of the operating table and located outside the placement groove through a hinge.

[0017] By designing the operating table with special placement slots and baffles, the convenience and safety of equipment use are enhanced to protect samples and equipment and improve user experience.

[0019] By setting up operation controllers and data displays, automatic control of the test process and real-time data display are achieved. Automatic control reduces human errors, and the data display provides real-time feedback of test results, optimizing the test process and data analysis efficiency.

[0020] In a preferred solution, four supporting legs are fixedly connected to the bottom of the operating table.

[0021] By equipping the bottom of the operating table with four supporting legs, the stability of the equipment is ensured and the stability of the equipment during use is guaranteed.

[0022] The adhesive viscosity testing device provided by the utility model has the following advantages:

[0023] In the utility model, when the adhesive viscosity testing device is in use, the adhesive is coated on two test plates, and then the upper alignment plate is compressed by the spring during the test, so that a buffering effect can be achieved when the tension of the adhesive is detected. On the one hand, the force application process can be smoothed, making the increase in force more uniform and continuous, which helps to accurately measure the performance of the adhesive at different stress levels, thereby obtaining more accurate and consistent test results. On the other hand, the load of the adhesive is gradually increased rather than suddenly applied. Through buffering, the test equipment can better simulate such actual use conditions, so the test results can better reflect the performance of the adhesive in actual applications, greatly improving the work quality and use efficiency compared with traditional devices.

[0047] Working principle: When the above-mentioned adhesive viscosity testing equipment is in use, a U-shaped plate 2 is connected to the top of the operating table 1 of the equipment, which is the main structure of the entire equipment and provides support and stability. Two sliding rods 3 are fixed at the bottom of the U-shaped plate 2 to support the vertical movement of the upper alignment plate 4 and the lower alignment plate 6.

The operation controller 17 is used to control the start, stop and movement speed of the cylinder 13, allowing the operator to adjust the pressure as needed. The measurement results of the tension detector 14 are transmitted to the data display 18 through electrical connection, and the viscosity data of the adhesive is displayed in real time during the experiment. The load of the adhesive is gradually increased rather than suddenly applied. Through buffering, the test equipment can better simulate this actual use condition, so the test results can better reflect the performance of the adhesive in actual application, which greatly improves the operation quality and use efficiency compared with traditional devices.
