Description

Technical Field

[0001] This utility model relates to the field of rubber sealing plug inspection technology, specifically a rubber sealing plug inspection device. Background Technology

[0002] With the development of industry, various rubber products are playing an increasingly important role in our lives. Before each rubber product is mass-produced, it is necessary to inspect the test samples to ensure the quality and performance of the rubber product. Rubber sealing plugs are a type of rubber product, and testing equipment is needed when testing the tensile strength of rubber sealing plugs.

[0003] For example, the utility model patent with authorization announcement number CN210719924U discloses a tensile strength testing device for rubber products. This device is equipped with a movable strip plate. The distance of tearing and separation of the rubber product is measured by the strip plate. With the tensile force scale engraved on the strip plate, the actual test data can be obtained quickly. However, when the rubber product begins to break, the operator needs to record the corresponding tensile force value according to the scale indicated by the pointer on the surface of the strip plate. This method relies on the operator's visual observation. The operator needs to pay attention to both the breakage of the rubber product and the pointer scale, which is prone to errors. In addition, this device cannot test the tensile strength of rubber products at different temperatures and needs to be improved.

[0004] Therefore, we propose a rubber sealing plug testing device to solve the problems mentioned above. Utility Model Content

When a rubber product begins to break, the staff needs to record the corresponding tensile force value according to the scale indicated by the pointer on the surface of the moving plate. This method relies on the staff's visual observation. On the one hand, the staff needs to pay attention to the breakage of the rubber product, and on the other hand, the staff needs to pay attention to the pointer scale. This method is prone to errors. On the other hand, the device cannot test the tensile strength of rubber products at different temperatures. These problems need to be improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rubber sealing plug inspection device, comprising: a base, on which an inspection box is disposed;

[0030] like Figures 1-7 As shown, two clamping mechanisms 4 are installed inside the inspection box 2 to clamp and pull the rubber sealing plug. A screw 5 is installed inside the inspection box 2 to control the movement of the clamping mechanisms 4. A motor box 6 is installed on the outside of the inspection box 2. A motor connected to the screw 5 is installed inside the motor box 6. A first thread 51 and a second thread 52 are symmetrically arranged on the screw 5. The first thread 51 and the second thread 52 are in opposite directions. The rotation of the screw 5 can control the two clamping mechanisms 4 to move closer or further apart.

[0031] like Figures 1-6 As shown, a guide mechanism 7 is symmetrically arranged inside the inspection box 2. The guide mechanism 7 includes two receiving blocks 71 fixed on the inner wall of the inspection box 2. A first guide rod 72 is connected between the receiving blocks 71. Movable grooves 711 are opened on the opposite sides of the receiving blocks 71. Limiting posts 73 are connected in the movable grooves 711. A second guide rod 74 is arranged between the two movable grooves 711. A sliding hole is opened on the second guide rod 74 to slide and connect with the limiting post 73. A bracket 8 for supporting the temperature regulating component 3 is provided on the base 1. A support rod 9 is provided on the bracket 8. A guide wheel 10 is provided at the top of the support rod 9. A pull line 11 is connected between the second guide rod 74 and the upper temperature regulating plate 32. The pull line 11 overlaps with the guide wheel 10.

[0032] like Figures 1-7As shown, the clamping mechanism 4 includes a first moving plate 41, a second moving plate 42, and two clamping plates 43. A tension sensor 44 is installed between the two clamping plates 43 and the first and second moving plates 41 and 42. A U-shaped plate 45, threadedly connected to a screw 5, is installed at the bottom of the first moving plate 41. An electric telescopic rod 46 is installed on the first moving plate 41, and its output shaft is connected to the second moving plate 42. A first limiting rod 47 is symmetrically connected to the upper surface of the first moving plate 41. A first limiting hole, slidably connected to the first limiting rod 47, is opened on the second moving plate 42. A first limiting plate 48 is connected to the top of the first limiting rod 47. First guide holes, slidably connected to a first guide rod 72, are opened at both ends of the first moving plate 41. Second guide holes, slidably connected to a second guide rod 74, are opened at both ends of the second moving plate 42. Through the cooperation of the guiding mechanism 7, the clamping mechanism 4, the temperature regulating component 3, the pull wire 11, and the guide wheel 10, the clamping mechanism 4... When the rubber sealing plug is clamped, the lower temperature regulating plate 31 and the upper temperature regulating plate 32 of the temperature regulating component 3 can be opened to facilitate the clamping mechanism 4 to pull the rubber sealing plug to move, preventing the closed temperature regulating component 3 from interfering with the inspection. The base 1 is equipped with a controller 12 that is electrically connected to the tension sensor 44, and the base 1 is equipped with a control panel 19.

The clamping mechanism 4 is equipped with a pointer 16 corresponding to the scale lines 15. With this configuration, when the rubber sealing plug breaks during the clamping mechanism 4 pulling the rubber sealing plug to move, the change in force will trigger the tension sensor 44. The tension sensor 44 will feed back the signal to the controller 12, and the controller 12 will control the motor to stop working. The clamping mechanism 4 and the pointer 16 will then stop moving, and the reading can be recorded by the cooperation of the pointer 16 and the scale lines 15.

[0033] Specifically, by activating the electric telescopic rod 46, the two clamping plates 43 are closed, and the second guide rod 74 moves. The upper temperature regulating plate 32 is moved by the pull line 11, opening the temperature regulating component 3. Then, the rubber sealing plug is placed into the material trough 33. Activating the electric telescopic rod 46 again opens the two clamping plates 43, and the upper temperature regulating plate 32 moves under the action of the compression spring, closing with the lower temperature regulating plate 31. Depending on actual needs, the electric heating tube 34 is activated to heat the rubber sealing plug in the material trough 33, or, through the cooperation of the refrigeration equipment, the inlet pipe 17, and the outlet pipe 18, low-temperature coolant is introduced into the cooling chamber 35 to cool the rubber sealing plug in the material trough 33. The temperature is adjusted, and then the screw 5 is driven by the motor to rotate, causing the two clamping mechanisms 4 to move toward the temperature regulating component 3. Then, the electric telescopic rod 46 is activated to close the two clamping plates 43 of the clamping mechanism 4, clamping the rubber sealing plug. At the same time, the temperature regulating component 3 opens. Then, the motor is started in reverse, causing the two clamping mechanisms 4 to pull the rubber sealing plug away. When the rubber sealing plug breaks, the change in force will trigger the tension sensor 44, which will feed back the signal to the controller 12. The controller 12 controls the motor to stop working, and the clamping mechanism 4 and the pointer 16 will stop moving. The reading can then be recorded by the interaction between the pointer 16 and the scale line 15.
