Description

Technical Field

[0001] This utility model relates to the field of adhesive performance testing technology, and in particular to an adhesive performance testing device. Background Technology

[0002] Adhesives, also known as "bonding agents" or "adhesives (binders)," are substances that firmly bond two or more parts or materials together through interfacial adhesion and cohesion (chemical and physical forces). They include epoxy resins, acrylic resins, polyurethanes, and others.

[0003] According to research, existing adhesive performance testing devices typically use springs to test their performance. Since adhesives require a certain amount of tension to separate, the springs will be stretched due to this tension. When the adhesive viscosity reaches its limit for separation, the bonded parts will swing due to the spring's rebound, which can easily cause injury to people in the vicinity.

[0004] Therefore, those skilled in the art have provided an adhesive performance testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an adhesive performance testing device. This device can reduce the rebound amplitude of the adhesive plate under the reaction force of the tension spring, thereby protecting the safety of surrounding personnel and reducing the physical exertion of the tester when turning the handle, thus providing convenience for the tester's operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adhesive performance testing device includes a support plate and two positioning rods. The two positioning rods are fixedly disposed between two support plates and located on both sides. A tension assembly is disposed at the lower end of the upper support plate, the tension assembly including a tension sensor and an upper adhesive plate, and a buffer protection mechanism. A pressure assembly is disposed at the upper end of the lower support plate, the pressure assembly including a lower adhesive plate, a screw, and a pressure spring, and a ball bearing mechanism is disposed inside the pressure assembly. Data transmission conversion lines are fixedly connected to both the tension sensor and the pressure sensor.

[0008] The buffer protection mechanism includes a buffer collar and two sliding rings. The buffer collar is slidably disposed on the upper end of the upper adhesive plate. The two sliding rings are respectively slidably disposed on corresponding positioning rods. Connecting rods are fixedly disposed on both sides of the upper end of the buffer collar. One side of each of the two connecting rods is fixedly connected to one side of the corresponding sliding ring. Buffer springs are sleeved and connected to the upper end of each of the two sliding rings and located on the corresponding positioning rods.

[0009] Through the above technical solution, the buffer protection mechanism can reduce the rebound amplitude of the upper adhesive plate under the reaction force of the tension spring when the upper adhesive plate is separated from the lower adhesive plate, thus avoiding injury to surrounding personnel caused by the rebound force of the upper adhesive plate. In addition, the buffer collar suspended in the air ensures that the tension spring is not affected by the buffer spring during the tension process, thereby ensuring the accuracy of tension and pressure data and guaranteeing the accuracy of adhesive performance testing.

[0010] Furthermore, the roller ball mechanism includes roller balls and a rotating block. There are multiple roller balls. The lower adhesive plate has an inner cavity. The multiple roller balls are equidistantly rotatably disposed inside the lower adhesive plate and located in the inner cavity. The rotating block is fixedly disposed on the upper end of the screw and rotates inside the inner cavity.

[0011] The above technical solution makes the screw rotation and the lower adhesive plate move more smoothly through the roller ball mechanism. In addition, the sliding of the limiting plate on the positioning rod can greatly reduce the torsional deformation generated during the compression process of the pressure spring, which provides accuracy for the pressure of adhesive performance testing. At the same time, it reduces the frictional resistance between the rotating block and the lower adhesive plate when the tester turns the handle, which provides convenience for the tester's operation.

[0012] Furthermore, mounting hooks are fixedly provided on both sides of the upper end of the support plate near its upper end;

[0013] The above technical solution allows the bottom of the device to be suspended by installing a fixing hook, so that the tester can move the screw down to test the tensile and compressive properties of the adhesive.

[0014] Furthermore, the tension sensor is fixedly mounted on the upper end of the support plate located at the upper end, and a tension spring is fixedly mounted on the lower end of the support plate near the upper end of the tension sensor, and the upper adhesive plate is fixedly mounted on the lower end of the tension spring.

[0015] The above technical solution allows for the testing of the tensile strength of adhesive properties using a tension spring and a tension sensor, and the data can be uploaded.

[0016] Furthermore, the lower adhesive plate is slidably disposed on the upper end of the support plate located at the lower end, the screw is rotatably disposed at the lower end of the lower adhesive plate, and the lower end of the screw is fixedly disposed with a handle through the lower end of the support plate located at the lower end;

[0017] With the above technical solution, the screw can be moved downward by the throttle, thereby causing the lower adhesive plate to move downward along with the upper adhesive plate.

[0018] Furthermore, a pressure sensor is fixedly installed inside the support plate at its lower end and at the screw, and the pressure spring is sleeved and connected between the lower adhesive plate and the pressure sensor and is located at the screw;

[0019] The above technical solution allows for pressure testing of adhesive properties using pressure sensors and pressure springs, with the data then uploaded.

[0020] Furthermore, limit plates are fixedly provided on both sides of the lower adhesive plate and near its lower end. Each of the two limit plates is provided with a sliding hole, and the two limit plates slide on the corresponding positioning rod through the sliding hole.

[0021] By using the above technical solution, the limiting plate slides on the corresponding positioning rod through the sliding hole, which can prevent the pressure spring from twisting and deforming when the screw drives the lower adhesive plate to move down, so as not to affect the pressure data of the adhesive performance.

[0022] Furthermore, the upper ends of both buffer springs are fixedly connected to the lower end of the support plate near their upper ends;

[0023] With the above technical solution, by fixing the upper end of the buffer spring to the lower end of the support plate near its upper end, the buffer collar can be suspended at the tension component, thus avoiding any impact on the tensile strength data of the adhesive performance.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes an adhesive performance testing device. This device can reduce the rebound amplitude of the upper adhesive plate under the reaction force of the tension spring when the upper adhesive plate is separated from the lower adhesive plate through a buffer protection mechanism, so as to avoid the rebound force of the upper adhesive plate causing injury to surrounding personnel. In addition, through the suspended buffer collar, the tension spring is not affected by the buffer spring during the tension process, thereby ensuring the accuracy of tension and pressure data and ensuring the accuracy of adhesive performance testing.

[0026] 2. The present invention proposes an adhesive performance testing device. This device makes the screw rotation and the lower adhesive plate move more smoothly through the roller ball mechanism. In addition, the limiting plate slides on the positioning rod, which can greatly reduce the torsional deformation generated during the compression process of the pressure spring, thus providing accuracy for the pressure of adhesive performance testing. At the same time, it reduces the frictional resistance generated between the rotating block and the lower adhesive plate when the tester turns the handle, thus providing convenience for the tester's operation.

[0027] 3.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1-5 This utility model provides a specific embodiment: an adhesive performance testing device, including a support plate 1 and two positioning rods 2. The two positioning rods 2 are fixedly disposed between two support plates 1 and located on both sides. A tension assembly 4 is disposed at the lower end of the upper support plate 1. The tension assembly 4 includes a tension sensor 41 and an upper adhesive plate 43. A buffer protection mechanism 400 is disposed on the tension assembly 4. A pressure assembly 5 is disposed at the upper end of the lower support plate 1. The pressure assembly 5 includes a lower adhesive plate 51, a screw 52, ​​and a pressure spring 55. The pressure assembly 5 contains... The device is equipped with a ball bearing mechanism 500. Data transmission conversion lines 6 are fixedly connected to both the tension sensor 41 and the pressure sensor 54. Mounting hooks 3 are fixedly installed on both sides of the upper end of the support plate 1. These hooks allow the bottom of the device to be suspended, enabling the tester to lower the screw 52 for tensile and compressive testing of the adhesive properties. The tension sensor 41 is fixedly mounted on the upper end of the support plate 1. A tension spring 42 is fixedly installed at the lower end of the support plate 1, penetrating the lower end of the tension sensor 41. The upper adhesive plate 43 is fixedly mounted below the tension spring 42. The tension spring 42 and tension sensor 41 can test the tensile strength of the adhesive and upload the data. The lower adhesive plate 51 is slidably mounted on the upper end of the support plate 1 located at the lower end. The screw 52 is rotatably mounted on the lower end of the lower adhesive plate 51. The lower end of the screw 52 passes through the lower end of the support plate 1 and is fixedly mounted with a handle 53. The screw 52 can be moved downward by the handle 53, thereby causing the lower adhesive plate 51 to drive the upper adhesive plate 43 to move downward. A pressure sensor 54 is fixedly mounted inside the support plate 1 at the lower end and located at the screw 52. A pressure spring 55 is sleeved and connected to the lower adhesive plate 51 and the pressure sensor. The pressure sensor 54 and the pressure spring 55 are located between the device 54 and at the screw 52. The pressure sensor 54 and the pressure spring 55 can test the pressure of the adhesive performance and upload the data. Limiting plates 56 are fixedly installed on both sides of the lower adhesive plate 51 and near its lower end. Each limiting plate 56 has a sliding hole 57. The two limiting plates 56 slide on the corresponding positioning rod 2 through the sliding hole 57. By allowing the limiting plates 56 to slide on the corresponding positioning rod 2 through the sliding hole 57, the pressure spring 55 can be prevented from twisting and deforming when the screw 52 drives the lower adhesive plate 51 to move downward, so as not to affect the pressure data of the adhesive performance.

[0038] The buffer protection mechanism 400 includes a buffer collar 401 and two sliding rings 402. The buffer collar 401 is slidably disposed on the upper end of the upper adhesive plate 43, and the two sliding rings 402 are respectively slidably disposed on corresponding positioning rods 2. Connecting rods 403 are fixedly disposed on both sides of the upper end of the buffer collar 401, and one side of each of the two connecting rods 403 is fixedly connected to one side of the corresponding sliding ring 402. Buffer springs 404 are sleeved and connected to the upper end of each of the two sliding rings 402 and located on the corresponding positioning rods 2. The buffer protection mechanism 400 can reduce the stress on the upper adhesive plate 43 when it separates from the lower adhesive plate 51. The rebound amplitude of the tension spring 42 prevents the rebound force of the adhesive plate 43 from causing injury to surrounding personnel. Furthermore, the suspended buffer ring 401 ensures that the tension spring 42 is not affected by the buffer spring 404 during the tension process, thereby ensuring the accuracy of tension and pressure data and guaranteeing the accuracy of adhesive performance testing. The upper ends of both buffer springs 404 are fixedly connected to the lower end of the support plate 1 above them. By fixing the upper ends of the buffer springs 404 to the lower end of the support plate 1 above them, the buffer ring 401 can be suspended at the tension assembly 4, avoiding any impact on the tension data of the adhesive performance.

[0039] Reference Figure 1-4 6. The roller ball mechanism 500 includes roller balls 501 and rotating block 502. There are multiple roller balls 501. The lower adhesive plate 51 has an inner cavity 503. Multiple roller balls 501 are equidistantly rotatably arranged inside the lower adhesive plate 51 and located in the inner cavity 503. The rotating block 502 is fixedly arranged on the upper end of the screw 52 and rotates inside the inner cavity 503. The roller ball mechanism 500 makes the screw 52 rotate and drive the lower adhesive plate 51 to move down more smoothly. In addition, it cooperates with the limiting plate 56 to slide on the positioning rod 2, which can greatly reduce the torsional deformation generated during the downward pressing of the pressure spring 55, providing accuracy for the pressure of adhesive performance testing. At the same time, it reduces the frictional resistance generated between the rotating block 502 and the lower adhesive plate 51 when the tester turns the handle 53, providing convenience for the tester's operation.

[0040] Working principle: When using this adhesive performance testing device, first use the mounting hook 3 to suspend the lower end of the device. Then, apply adhesive to the upper adhesive plate 43 and the lower adhesive plate 51 respectively. Then, stack the upper adhesive plate 43 and the lower adhesive plate 51 together and wait for a while for them to bond under the action of the adhesive. Then, manually turn the handle 53. At this time, the screw 52 is driven by the rotation of the rotating block 502 inside the lower adhesive plate 51 and the sliding action of the limiting plate 56 on the positioning rod 2, which drives the lower adhesive plate 51 to move downward in a balanced manner. At the same time, the upper adhesive plate 43 moves downward synchronously due to the downward action of the lower adhesive plate 51. When manually turning the handle 53, the rotating block 502 is reduced by the action of the roller ball 501, which reduces the frictional resistance between it and the lower adhesive plate 51. The force sensor 41 and the pressure sensor 54, under the action of the tension spring 42 and the pressure spring 55, transmit the data to the external display screen through the data transmission conversion line 6, so that the operator can intuitively view the test performance of the adhesive. When the viscosity of the adhesive reaches the limit separation, the upper adhesive plate 43 separates from the lower adhesive plate 51. At this time, the upper adhesive plate 43 moves upward under the rebound action of the tension spring 42. When the upper adhesive plate 43 moves upward and rebounds, the upper adhesive plate 43 overlaps with the buffer collar 401, and the buffer spring 404 and the sliding ring 402 can reduce the upward rebound amplitude of the upper adhesive plate 43, so as to avoid the rebound force of the upper adhesive plate 43 from causing injury to the surrounding personnel.
