Description

Technical Field

[0001] This utility model relates to the field of flexible resin board testing technology, specifically a flexible resin board hardness testing device. Background Technology

[0002] Flexible resin sheets are a new type of material that is widely used due to their flexibility and bending properties. They are mainly made of materials such as polyimide, polypropylene, and polyester, but combinations of other materials are also possible.

[0003] The hardness testing device for flexible resin plates disclosed in patent application CN215910281U includes: a frame; a hardness testing mechanism supported on the frame, the hardness testing mechanism including: a counterweight plate movably mounted on the frame, a mounting base connected to the bottom of the counterweight plate, a probe fixedly connected to the bottom of the counterweight plate, a marking line set on the probe, and a telescopic drive component set on the frame for driving the counterweight plate to move up and down; and a temperature regulating mechanism supported on the frame, the temperature regulating mechanism including: a support platform set on the frame, a heater set on the frame and located inside the support platform, a fan connected to the heater, and a plurality of air guide holes opened on the support platform. Through the above configuration, the hardness test results can be displayed intuitively, and testing can be performed at different temperatures, resulting in more comprehensive test results.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] After the flexible resin board is processed, it needs to be sampled and inspected by a hardness tester to ensure that the hardness of the same batch of flexible resin boards meets the standard. When testing flexible resin boards, the existing hardness tester generally places the flexible resin board on a placement plate and pushes the placement plate up by an electric push rod so that the flexible resin board contacts the test end on the hardness tester to obtain the test result. However, considering that the hardness tester does not have the function of limiting the flexible resin board during the testing process, the flexible resin board is prone to displacement, which affects the accuracy of the test. Utility Model Content

[0006] The purpose of this invention is to provide a flexible resin board hardness testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A hardness testing device for flexible resin boards includes a hardness tester, an electric push rod, and a placement plate. The electric push rod is fixedly mounted on the hardness tester, and the placement plate is fixedly mounted on the output end of the electric push rod. Two limiting blocks are provided on the top of the placement plate, and a support block is fixedly connected to the bottom of the limiting blocks. A sliding block is fixedly connected to the side of the support block near the placement plate. Sliding grooves that cooperate with the sliding blocks are provided on both sides of the placement plate. A housing is fixedly connected to the side of the two limiting blocks that are far apart from each other. A moving mechanism is provided inside the housing, and a pressing mechanism is provided on the side of the limiting blocks that is far away from the housing.

[0009] The moving mechanism includes a linkage block disposed inside the housing. Both sides of the linkage block are fixedly connected to traction rods. One end of the traction rod is fixedly connected to a positioning rod. The top of the placement plate is provided with a positioning hole for use with the positioning rod. The top of the linkage block is fixedly connected to a drive rod. The top of the drive rod extends through to the top of the housing and is fixedly connected to a pull ring.

[0010] Preferably, the pressing mechanism includes a mating block fixedly connected to one side of the limiting block, a threaded rod threadedly connected to the top of the mating block, a turning block fixedly connected to the top of the threaded rod, a bearing provided at the bottom of the threaded rod, and a pressure plate rotatably connected through the bearing, and a threaded hole for mating with the threaded rod is provided at the top of the mating block.

[0011] Preferably, two guide blocks are fixedly connected to one side of the pressure plate, and a guide groove is provided on one side of the limiting block to cooperate with the guide blocks.

[0012] Preferably, an anti-slip pad is fixedly connected to the bottom of the pressure plate, and the anti-slip pad is made of rubber.

[0013] Preferably, a tension spring is fixedly connected to the bottom of the linkage block, and the bottom of the tension spring is fixedly connected to the inner wall of the housing.

[0014] Preferably, the number of positioning holes is several, and they are evenly distributed on the top of the placement plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting up a moving mechanism, enables the flexible resin plate sample to be placed on top of the placement plate. Then, pulling the pull ring upwards moves the drive rod and linkage block upwards. The linkage block moves the traction rod and positioning rod upwards, causing the positioning rod to leave the interior of the positioning hole. Then, the position of the support block and the placement plate can be adjusted along the trajectory of the sliding block and the sliding groove, so that the two placement plates clamp the flexible resin plate. After releasing the pull ring, the tension generated by the tension spring will move the linkage block, traction rod and positioning rod downwards, causing the positioning rod to enter the corresponding positioning hole, thereby completing the positioning of the placement plate and restricting the position of the flexible resin plate, preventing displacement during the testing process.

[0017] 2. By setting up a pressing mechanism, this utility model can adjust the two limiting blocks to both sides of the flexible resin plate, and then rotate the screwing block to drive the threaded rod to rotate inside the threaded hole. This causes the bearing and the pressure plate to move downward along the trajectory of the guide block and the guide groove. Then the pressure plate presses down on the flexible resin plate, thereby avoiding the phenomenon of the flexible resin plate lifting during the testing process and improving the accuracy of the test.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A hardness testing device for flexible resin board includes a hardness tester 1, an electric push rod 2, and a placement plate 3. The electric push rod 2 is fixedly installed on the hardness tester 1, and the placement plate 3 is fixedly installed on the output end of the electric push rod 2. Two limiting blocks 4 are provided on the top of the placement plate 3, and a support block 5 is fixedly connected to the bottom of the limiting block 4. A sliding block 6 is fixedly connected to the side of the support block 5 near the placement plate 3. Sliding grooves 7 that cooperate with the sliding blocks 6 are provided on both sides of the placement plate 3. A housing 8 is fixedly connected to the side of the two limiting blocks 4 that is far away from each other. A moving mechanism is provided inside the housing 8, and a pressing mechanism is provided on the side of the limiting blocks 4 that is far away from the housing 8.

[0028] The moving mechanism includes a linkage block 9 disposed inside the housing 8. Both sides of the linkage block 9 are fixedly connected to traction rods 10. One end of the traction rod 10 is fixedly connected to a positioning rod 11. The top of the placement plate 3 is provided with a positioning hole 12 that cooperates with the positioning rod 11. The top of the linkage block 9 is fixedly connected to a drive rod 13. The top of the drive rod 13 extends through to the top of the housing 8 and is fixedly connected to a pull ring 14.

[0029] In this embodiment, considering that the hardness tester 1 does not have the function of limiting the flexible resin plate during the testing process, the flexible resin plate is prone to displacement, which affects the accuracy of the test. Therefore, by setting a moving mechanism, the flexible resin plate sample can be placed on the top of the placement plate 3, and then the pull ring 14 is pulled upward, which drives the drive rod 13 and the linkage block 9 to move upward. The linkage block 9 drives the traction rod 10 and the positioning rod 11 to move upward, so that the positioning rod 11 leaves the interior of the positioning hole 12. Then, the position of the support block 5 and the placement plate 3 can be adjusted along the trajectory of the sliding block 6 and the sliding groove 7, so that the two placement plates 3 clamp the flexible resin plate. Then, the pull ring 14 is released, and the tension generated by the tension spring 23 will drive the linkage block 9, the traction rod 10 and the positioning rod 11 to move downward, so that the positioning rod 11 enters the interior of the corresponding positioning hole 12, thereby completing the positioning of the placement plate 3, thereby limiting the position of the flexible resin plate and avoiding displacement during the testing process.

[0030] This invention addresses the problem that the hardness tester 1 lacks the function of limiting the position of the flexible resin board during the testing process, which can easily cause the flexible resin board to shift and thus affect the accuracy of the test.

[0031] A tension spring 23 is fixedly connected to the bottom of the linkage block 9, and the bottom of the tension spring 23 is fixedly connected to the inner wall of the housing 8.

[0032] In this embodiment, by setting a tension spring 23, when the pull ring 14 is released, the tension force generated by the tension spring 23 can drive the linkage block 9, the traction rod 10 and the positioning rod 11 to move downward, thereby achieving the function of resetting.

[0033] The number of positioning holes 12 is several, and they are evenly distributed on the top of the placement plate 3.

[0034] In this embodiment, by setting a number of positioning holes 12, the positioning rod 11 can enter the corresponding positioning hole 12 after the limiting block 4 is adjusted, so as to quickly fix the limiting block 4.

[0035] Example 2:

[0036] Based on Embodiment 1, in this embodiment, the moving mechanism can control the two limiting blocks 4 to restrict the flexible resin plate. However, the flexible resin plate may still warp during the testing process, which will affect the accuracy of the test. In this application, the pressing mechanism includes a mating block 15 fixedly connected to one side of the limiting block 4. The top of the mating block 15 is threadedly connected to a threaded rod 16. The top of the threaded rod 16 is fixedly connected to a turning block 17. The bottom of the threaded rod 16 is provided with a bearing 18, and a pressure plate 19 is rotatably connected through the bearing 18. The top of the mating block 15 is provided with a threaded hole 24 that cooperates with the threaded rod 16.

[0037] In this embodiment, by setting a pressing mechanism, after the two limiting blocks 4 are adjusted to the two sides of the flexible resin plate, the screwing block 17 is rotated to drive the threaded rod 16 to rotate inside the threaded hole 24, so that the bearing 18 and the pressure plate 19 move downward along the trajectory of the guide block 20 and the guide groove 21. Then the pressure plate 19 presses the flexible resin plate, thereby avoiding the phenomenon of the flexible resin plate lifting during the detection process, and thus improving the accuracy of the detection.

[0038] This solves the problem that flexible resin boards can warp during testing, which can affect the accuracy of the tests.

[0039] Two guide blocks 20 are fixedly connected to one side of the pressure plate 19, and a guide groove 21 that cooperates with the guide blocks 20 is provided on one side of the limiting block 4.

[0040] In this embodiment, by setting guide block 20 and guide groove 21, when threaded rod 16 rotates to transmit power to pressure plate 19, pressure plate 19 is restricted to move downward along the trajectory of guide block 20 and guide groove 21, thus limiting the movement trajectory.

[0041] The bottom of the pressure plate 19 is fixedly connected to an anti-slip pad 22, which is made of rubber.

[0042] In this embodiment, by setting the anti-slip pad 22, the friction between the pressure plate 19 and the flexible resin board can be increased, thus playing an anti-slip role and preventing damage to the surface of the flexible resin board.

[0043] Working principle: The user places the flexible resin plate sample on top of the placement plate 3, and then pulls the pull ring 14 upwards, which drives the drive rod 13 and the linkage block 9 to move upwards. The linkage block 9 drives the traction rod 10 and the positioning rod 11 to move upwards, so that the positioning rod 11 leaves the interior of the positioning hole 12. Then, the position of the support block 5 and the placement plate 3 can be adjusted along the trajectory of the sliding block 6 and the sliding groove 7, so that the two placement plates 3 clamp the flexible resin plate. After releasing the pull ring 14, the tension generated by the tension spring 23 will drive the linkage block 9, the traction rod 10 and the positioning rod 11 downwards, so that the positioning rod 11 enters the interior of the corresponding positioning hole 12, thereby completing the positioning of the placement plate 3, thus limiting the position of the flexible resin plate and preventing displacement during the testing process.

[0044] After the two limit blocks 4 are adjusted to the two sides of the flexible resin plate, the screwing block 17 is rotated to drive the threaded rod 16 to rotate inside the threaded hole 24, so that the bearing 18 and the pressure plate 19 move downward along the trajectory of the guide block 20 and the guide groove 21. Then the pressure plate 19 presses down on the flexible resin plate, thereby avoiding the phenomenon of the flexible resin plate lifting during the testing process and improving the accuracy of the test.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
