Description

Technical Field

[0001] The utility model relates to the technical field of binder measurement and evaluation, and particularly relates to a structure for quickly evaluating the bonding force of a binder. Background Technique

[0002] A binder, also known as an adhesive or glue, is a non-metallic medium material that tightly connects one object to another. It has a wide range of applications in daily life, industry, building materials, metallurgy, agriculture and other fields. The bonding force is one of the core indicators for evaluating the performance of adhesives, directly affecting the bonding effect and overall quality of products. By evaluating the bonding force, it can be ensured that the adhesive can firmly bond the adherend during use and achieve the expected use effect.

[0003] During the production and distribution of binders, it is usually necessary to quickly evaluate the bonding force of binders to ensure production and work efficiency. At present, for the quick evaluation of the bonding force of binders, it is usually to prepare two test samples and apply the binder. One end of the two specimens is fixed, and a tensile force is applied to the other end. The bonding strength is evaluated by measuring the maximum value of the applied tensile force. Although this evaluation method is fast, during the application of the tensile force, it is difficult to ensure that the force is applied perpendicular to the bonding surface of the binder. When there is an angular deviation between the direction of the tensile force and the perpendicular direction of the bonding surface of the binder, it will cause a large error in the evaluation result of the bonding force of the binder. For this reason, this application proposes a structure for quickly evaluating the bonding force of binders. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structure for quickly evaluating the bonding force of a binder, with a simple and reasonable overall structure, which can be used for the on-site quick evaluation of the bonding force of the binder, and is easy to operate and has strong practicability.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A structure for quickly evaluating the bonding force of a binder includes a substrate, on which a first standard plate for applying the binder and a second standard plate for bonding with the binder are arranged, and the first standard plate is fixedly connected to the substrate; a tensiometer arranged above the substrate, which is used to pull the second standard plate away from the first standard plate and measure the tensile force, and a guiding member for guiding the tensiometer to pull perpendicular to the substrate is arranged on the substrate.

[0007] Preferably, the guiding member is a pair of guide rails vertically fixed on the upper surface of the substrate. The pair of guide rails are respectively located on both sides of the first standard plate and the second standard plate. Guide grooves are vertically opened on the guide rails, and guiding convex blocks slidably fitted with the guide grooves are arranged at the bottom end of the side wall of the tensiometer.

[0008] Preferably, a pull ring is provided on the upper surface of the second standard plate, a hook for hooking with the pull ring is provided at the measuring end of the tensiometer, and a handle is provided at the top of the tensiometer.

[0009] Preferably, the guiding bump is arranged in a long strip structure, and the long strip guiding bump is distributed along the length direction of the guide rail.

[0010] Preferably, a threaded through groove is formed in the base plate, the first standard plate is in threaded connection with the threaded through groove, a groove capable of accommodating the second standard plate to be embedded is formed in the upper end surface of the first standard plate, and a retaining ring abutted against the lower surface of the base plate is arranged at the bottom end of the first standard plate.

[0012] Preferably, the telescopic rod is composed of at least three sleeves sleeved with each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Through the arrangement of the first standard plate and the second standard plate, the binder is evenly applied in the groove on the first standard plate, the second standard plate is embedded in the groove and bonded with the binder, the tensiometer pulls the second standard plate away from the first standard plate, records the tension measured by the tensiometer when the second standard plate is separated from the first standard plate, and judges the magnitude of the tension and the predetermined bonding force of the binder, so as to be used for evaluating the bonding force of the binder. Since the whole uses the second standard plate to realize the measurement without an external power supply, it is suitable for the on-site rapid evaluation of the bonding force of the binder.

[0015] Through the arrangement of the guiding member, during the process of the tensiometer pulling the second standard plate away from the first standard plate for evaluation, the guiding bump on the tensiometer slides along the guiding groove on the guide rail, and can guide the tensiometer perpendicular to the base plate, so that the tensiometer pulls the second standard plate vertically away from the first standard plate, ensuring the effectiveness of the tensiometer in evaluating the bonding force of the binder.

[0016] Through the arrangement of the auxiliary plate and the telescopic rod, pull the auxiliary plate away from the base plate, utilize the connection between the telescopic rod and the base plate and the auxiliary plate.

[0024] Embodiment

[0025] Please refer to Figures 1 to 4, the present utility model preferably provides a technical solution: a structure for quickly evaluating the bonding force of an adhesive, including a substrate 1, a first standard plate 2 for applying the adhesive and a second standard plate 3 for bonding with the adhesive are arranged on the substrate 1, and the first standard plate 2 is fixedly connected to the substrate 1; a tensiometer 4 is arranged above the substrate 1, which is used to pull the second standard plate 3 away from the first standard plate 2 and measure the tensile force. A guiding member 5 for guiding the tensiometer 4 to pull perpendicular to the substrate 1 is arranged on the substrate 1. In this structural manner, the adhesive is evenly applied on the first standard plate 2, the second standard plate 3 is bonded to the adhesive, the tensiometer 4 pulls the second standard plate 3 away from the first standard plate 2, and the tensile force measured by the tensiometer 4 when the second standard plate 3 is separated from the first standard plate 2 is recorded. By judging the magnitude of the tensile force and the predetermined bonding force of the adhesive, it can be used to evaluate the bonding force of the adhesive. Since the whole uses the second standard plate 3 for measurement without an external power supply, it is suitable for the on-site rapid evaluation of the bonding force of the adhesive. In addition, through the arrangement of the guiding member 5, during the evaluation process of the tensiometer 4 pulling the second standard plate 3 away from the first standard plate 2, the tensiometer 4 can be guided perpendicular to the substrate 1, so that the tensiometer 4 pulls the second standard plate 3 vertically away from the first standard plate 2, ensuring the effectiveness of the tensiometer 4 in evaluating the bonding force of the adhesive.

[0026] As a preferred implementation manner of this embodiment, the guiding member 5 is a pair of guide rails 8 vertically fixed on the upper surface of the substrate 1. The pair of guide rails 8 are respectively located on both sides of the first standard plate 2 and the second standard plate 3. A guide groove 9 is vertically opened on the guide rail 8. A guiding convex block 10 that is slidably fitted with the guide groove 9 is arranged at the bottom end of the side wall of the tensiometer 4. During the evaluation process of the tensiometer 4 pulling the second standard plate 3 away from the first standard plate 2, the guiding convex block 10 on the tensiometer 4 slides along the guide groove 9 on the guide rail 8, so that the tensiometer 4 can be guided perpendicular to the substrate 1. The guiding convex block 10 is set as a strip-shaped structure, and the strip-shaped guiding convex block 10 is distributed along the length direction of the guide rail 8, which can prevent the tensiometer 4 from rotating and swinging back and forth.

[0027] In this embodiment, a pull ring 14 is arranged on the upper surface of the second standard plate 3. The measuring end of the tensiometer 4 has a hook for hooking the pull ring 14. A handle 11 is arranged at the top end of the tensiometer 4. A threaded through groove 12 is opened on the substrate 1, and the first standard plate 2 is threadedly connected to the threaded through groove 12, which is convenient for replacing the first standard plate 2 and the second standard plate 3. Only by preparing the first standard plate 2 and the second standard plate 3 in batches, the bonding force of multiple batches of adhesives can be quickly evaluated. A groove 16 capable of accommodating the second standard plate 3 is opened on the upper end surface of the first standard plate 2, which is convenient for applying the adhesive. A retaining ring 15 that abuts against the lower surface of the substrate 1 is arranged at the bottom end of the first standard plate 2.

[0028] In a further embodiment, an auxiliary plate 6 is provided below the substrate 1, and a pair of telescopic rods 7 are provided on the substrate 1. The telescopic ends of the telescopic rods 7 are connected to the auxiliary plate 6. The telescopic rod 7 is composed of at least three sleeves 13 sleeved with each other. When the multiple sleeves 13 are extended, the auxiliary plate 6 can be stepped on and abutted against the ground to assist in fixing the substrate 1, which facilitates the evaluation and detection by pulling the tensiometer 4.

[0029] During use, during the production process or sales sampling inspection process of the adhesive, the adhesive is evenly applied in the groove 16 on the first standard plate 2, and the second standard plate 3 is embedded in the groove 16 and bonded to the adhesive. Then, the hook of the tensiometer 4 is hooked to the pull ring 14 on the second standard plate 3, and the handle 11 is held to pull the tensiometer 4 to pull the second standard plate 3 away from the first standard plate 2. Record the tension measured by the tensiometer 4 when the second standard plate 3 is separated from the first standard plate 2, and judge the magnitude of the tension and the predetermined bonding force of the adhesive, which can be used to evaluate the bonding force of the adhesive. Since the overall measurement is achieved by using the second standard plate 3 and no external power supply is required, it is suitable for the on-site rapid evaluation of the adhesive bonding force. In addition, the second standard plate 3 is hooked and connected to the tensiometer 4, and the first standard plate 2 is threadedly connected to the threaded through groove 12 on the substrate 1, which facilitates the replacement of the second standard plate 3 and the first standard plate 2. Only by preparing the first standard plate 2 and the second standard plate 3 in batches, the bonding forces of multiple batches of adhesives can be rapidly evaluated. Further, during the process of pulling the tensiometer 4 to pull the second standard plate 3 away from the first standard plate 2 for evaluation, the guiding convex block 10 on the tensiometer 4 slides along the guiding groove 9 on the guide rail 8, which can guide the tensiometer 4 perpendicular to the substrate 1, so that the tensiometer 4 pulls the second standard plate 3 vertically away from the first standard plate 2, ensuring the effectiveness of the evaluation of the adhesive bonding force by the tensiometer 4. Further, the auxiliary plate 6 is pulled away from the substrate 1. By using the connection between the substrate 1 and the auxiliary plate 6 by the telescopic rod 7, during the process of pulling the tensiometer 4 away from the substrate 1, the auxiliary plate 6 can be stepped on and abutted against the ground to assist in fixing the substrate 1. Pushing the auxiliary plate 6 close to the substrate 1 can be used for folding, which is easy to carry. The overall structure is simple and reasonable, which can be used for the on-site rapid evaluation of the adhesive bonding force, and the operation is simple and the practicability is strong.
