[0021] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] A high-strength plastic impact resistance testing device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] As Figures 1 to 9 shown, an embodiment of the present invention provides a high-strength plastic impact resistance testing device, including: a test control component 1, the test control component 1 includes a first embedded frame 2 and a second embedded frame 9. A first mounting frame 3 is provided inside the first embedded frame 2, and the side wall of the first mounting frame 3 is attached to the inner wall of the first embedded frame 2. A second mounting frame 10 is provided inside the second embedded frame 9, and the side wall of the second mounting frame 10 is attached to the inner wall of the second embedded frame 9.

[0024] A hardness recording control module 7 is provided at the bottom of the inner wall of the first mounting frame 3, and a hardness detection control module 11 is provided at the bottom of the inner wall of the second mounting frame 10. The hardness recording control module 7 transmits plastic impact resistance performance data to the hardness detection control module 11.

[0025] A displacement driving component 13, the displacement driving component 13 includes a gas flow limiting plate 15 and gas guide vanes 20. There are two groups of gas flow limiting plates 15, a driving rod 16 is provided between the two groups of gas flow limiting plates 15, a sliding bearing sleeve 17 is provided on the outer wall of the driving rod 16, and the gas guide vanes 20 are provided on the outer wall of the sliding bearing sleeve 17. There are multiple groups of gas guide vanes 20.

[0026] A working frame 21, the inner cavity of the working frame 21 is provided with plastic, an air delivery pipe 14 is provided above the plastic, the displacement driving component 13 is provided inside the air delivery pipe 14, and the test control component 1 is provided on both sides of the working frame 21.

[0027] In the specific application of the embodiments of the present invention, a first installation frame 3 is configured inside the first embedded frame body 2. The side wall of the first installation frame 3 is closely attached to the inner wall of the first embedded frame body 2, which not only enhances the overall stability but also facilitates subsequent installation and maintenance. Similarly, a second installation frame 10 is also provided inside the second embedded frame body 9, and its side wall is also closely attached to the inner wall of the second embedded frame body 9, which can effectively prevent the loosening or damage of components caused by vibration or external factors. At the bottom of the inner wall of the first installation frame 3, a hardness recording control module 7 is arranged, which is responsible for recording the hardness change of the plastic before and after being impacted. At the same time, a hardness detection control module 11 is placed at the bottom of the inner wall of the second installation frame 10, which receives the data from the hardness recording control module 7 and further processes this information to evaluate the impact resistance of the plastic. The data transmission between the two makes the testing process automated, reduces the influence of human intervention, and thus improves the reliability and consistency of the test results.

[0028] There are two groups of gas flow limiting plates 15 in total, which are connected by a driving rod 16. A sliding bearing sleeve 17 is sleeved on the outer surface of the driving rod 16, which not only ensures that the driving rod 16 can move smoothly between the flow limiting plates but also avoids unnecessary frictional losses. In addition, multiple groups of gas guiding vanes 20 are arranged on the outer wall of the sliding bearing sleeve 17. The gas guiding vanes 20 can guide the gas flow direction, and then affect the position movement of the plastic sample, so as to facilitate the simulation of the impact force under the actual use environment.

[0029] Before the formal start of the test, first, the plastic sample to be tested needs to be placed at the designated position inside the working frame body 21 and ensure that the sample is stable and immovable. When everything is ready, start the displacement driving assembly 13 to operate. The gas flow limiting plates 15 and the gas guiding vanes 20 work together to generate a specific pressure distribution by adjusting the gas flow path. Then, the sliding bearing sleeve 17 and the gas guiding vanes 20 move up and down along the length of the driving rod 16 under the drive of the air flow. Since the sliding bearing sleeve 17 is installed on the outside of the driving rod 16, there is almost no frictional resistance during the entire movement process, ensuring the smoothness and accuracy of the movement. As the displacement driving assembly 13 adjusts the flow intensity of the gas, it will then drive the hardness detection plate 28 to gradually approach the plastic sample until it reaches the preset position (contacting the surface of the plastic sample).

[0030] During this period, the hardness recording control module 7 monitors the hardness change on the surface of the plastic sample in real time and sends the collected data to the hardness detection control module 11 in a timely manner. After receiving the data, the hardness detection control module 11 analyzes and processes it, and calculates key indicators such as the hardness loss rate of the plastic sample.

[0031] Once a complete impact test is completed, the system will automatically stop running and enter the data analysis stage. At this stage, the hardness detection control module will comprehensively analyze the collected data and generate a detailed test report.

[0032] In a possible implementation, sliding connection blocks 4 are provided inside both the first mounting frame 3 and the second mounting frame 10. A buffer damping rod 6 is provided on the top surface of the sliding connection block 4. The hardness recording control module 7 and the hardness detection control module 11 are respectively provided at the bottom of the sliding connection block 4.

[0033] The sliding connection block 4 contacts the hardness recording control module 7, and the hardness recording control module 7 records the plastic impact resistance performance data. The sliding connection block 4 contacts the hardness detection control module 11, and the hardness detection control module 11 receives the plastic impact resistance performance data.

[0034] In the specific application of the embodiment of the present invention, sliding connection blocks 4 are provided inside both the first mounting frame 3 and the second mounting frame 10. A buffer damping rod 6 is provided on the top surface of the sliding connection block 4. The buffer damping rod 6 can effectively absorb the energy generated during the impact process, reduce the impact load on the equipment components caused by the plastic weight, thereby improving the stability and accuracy of the test. The hardness recording control module 7 and the hardness detection control module 11 are provided at the bottom of the sliding connection block 4, and are respectively used to record and detect the hardness change data of the plastic during the impact process.

[0035] During the test, the sliding connection block 4 is in direct contact with the hardness recording control module 7. When the plastic material is impacted, the sliding connection block 4 displaces under the action of the buffer damping rod 6 and transmits the impact force to the hardness recording control module 7. The hardness recording control module 7 automatically operates. The hardness recording control module 7 records in real time the hardness change data of the plastic during the impact process and transmits these data to the hardness detection control module 11. After receiving the data, the hardness detection control module 11 performs further analysis and processing to obtain the impact resistance performance index of the plastic material.

[0036] The sliding connection block 4 not only realizes the effective transmission of the impact force, but also reduces the vibration and impact load on the test device during the impact process through the damping action of the buffer damping rod 6, ensuring the smoothness of the test process and the accuracy of the data. At the same time, the coordinated operation of the hardness recording control module 7 and the hardness detection control module 11 realizes the real-time recording and analysis of the plastic impact resistance performance data, improving the test efficiency and data reliability.

[0037] In addition, the damping characteristics of the buffer damping rod 6 optimize the absorption and transmission process of the impact energy, ensuring that the test device can still maintain high precision and stability during long-term use. The integrated setting of the hardness recording control module 7 and the hardness detection control module 11 simplifies the structure of the test device, reduces the manufacturing cost, and at the same time improves the processing speed and accuracy of the test data.

[0038] In a possible implementation, a plastic placement frame 31 is provided inside the working frame body 21. Plastics are placed inside the plastic placement frame 31. A connecting rod 5 is provided on the side wall of the sliding connection block 4, and the connecting rod 5 is fixedly arranged on the outer wall of the plastic placement frame 31. As the plastics in the plastic placement frame 31 increase, the sliding connection block 4 moves inside the first installation frame 3 and the second installation frame 10, driving the plastic placement frame 31 to move inside the working frame body 21 through the connecting rod 5. Damping shock-absorbing rods 32 are provided around the bottom of the inner wall of the working frame body 21, and all four damping shock-absorbing rods 32 are arranged at the bottom of the plastic placement frame 31; fixing columns 23 are provided around the bottom of the working frame body 21, protective plates 24 are provided on the bottom surfaces of the four fixing columns 23, and anti-slip patterns are provided on the bottom surfaces of the four protective plates 24.

[0039] In the specific application of the embodiment of the present invention, the plastic placement frame 31 is used to fix the plastic material to be tested to ensure its stability during the test. The outer wall of the plastic placement frame 31 is fixedly connected to the sliding connection block 4 through the connecting rod 5. The sliding connection block 4 is arranged inside the first installation frame 3 and the second installation frame 10. As the plastics in the plastic placement frame 31 increase, the sliding connection block 4 moves inside the first installation frame 3 and the second installation frame 10, and drives the plastic placement frame 31 to move inside the working frame body 21 through the connecting rod 5, enabling the plastic placement frame 31 to automatically adjust its position according to the weight of the plastics, ensuring uniform stress on the plastics during the test, and thus improving the accuracy and reliability of the test.

[0040] Damping shock-absorbing rods 32 are provided around the bottom of the inner wall of the working frame body 21, and all four damping shock-absorbing rods 32 are arranged at the bottom of the plastic placement frame 31. The damping shock-absorbing rods 32 can effectively absorb the vibration and impact energy generated during the test, reduce the impact load on the working frame body 21 and the plastic placement frame 31, and thus improve the stability and accuracy of the test.

[0041] Fixing columns 23 are provided around the bottom of the working frame body 21, protective plates 24 are provided on the bottom surfaces of the four fixing columns 23, and anti-slip patterns are provided on the bottom surfaces of the protective plates 24. The fixing columns 23 enhance the overall stability of the working frame body 21, preventing the device from tilting or moving during the test. The anti-slip patterns on the protective plates 24 further improve the anti-slip performance of the device, ensuring that the device can be firmly fixed on the workbench surface during the test and avoiding affecting the test results due to sliding.

[0042] In a possible implementation, an air extraction pump 25 is provided at the bottom of the working frame 21. An air delivery pipe 14 is provided at the working end of the air extraction pump 25. Bearing seats 19 are provided on the outer walls of both gas flow limiting plates 15. Both ends of the driving rod 16 are provided on the outer walls of the two bearing seats 19. Telescopic damping rods 18 are provided on both outer walls of the sliding bearing sleeve 17. The other ends of the telescopic damping rods 18 are provided on the outer walls of the bearing seats 19. The gas flow limiting plates 15 and the gas guide vanes 20 control the gas flow direction and the gas delivery intensity.

[0043] At the bottom of the inner wall of the second embedded frame 9, an air extraction pump control module 12 is provided. The air extraction pump control module 12 is electrically connected to the air extraction pump 25 through a transmission wire. The bottom of the plastic placement frame 31 contacts the air extraction pump control module 12, automatically turning on the air extraction pump 25 to work.

[0044] In the specific application of the embodiment of the present invention, the working end of the air extraction pump 25 is connected to the air delivery pipe 14. The air delivery and control are realized through the operation of the air extraction pump 25. A displacement driving assembly 13 is provided inside the air delivery pipe 14. The displacement driving assembly 13 includes gas flow limiting plates 15 and gas guide vanes 20. The two gas flow limiting plates 15 are clamped inside the air delivery pipe 14. The driving rod 16 is provided between the two gas flow limiting plates 15. Bearing seats 19 are provided on the outer walls of both gas flow limiting plates 15. Both ends of the driving rod 16 are provided on the outer walls of the two bearing seats 19, ensuring that the sliding bearing sleeve 17 and the gas guide vanes 20 move smoothly along the outer wall of the driving rod 16. Telescopic damping rods 18 are provided on both outer walls of the sliding bearing sleeve 17. The other ends of the telescopic damping rods 18 are provided on the outer walls of the bearing seats 19. Through the damping effect of the telescopic damping rods 18, the vibration and impact load during the movement of the driving rod 16 are reduced, thereby improving the stability and accuracy of the test. The coordinated work of the gas flow limiting plates 15 and the gas guide vanes 20 can accurately control the gas flow direction and the delivery intensity, thereby realizing the precise adjustment of the displacement of the hardness detection plate 28 (pushing the hardness detection plate 28 up and down according to the air flow intensity, adjusting the distance between the hardness detection plate 28 and the plastic sample, and the extrusion force of the hardness detection plate 28 on the plastic sample under the action of different air flow intensities), thereby simulating different impact conditions through different extrusion forces.

[0045] At the bottom of the inner wall of the second embedded frame 9, there is an air pump control module 12. The air pump control module 12 is electrically connected to the air pump 25 through a transmission wire to achieve precise control of the air pump 25. The bottom of the plastic placement frame 31 contacts the air pump control module 12. When the plastic placement frame 31 moves inside the working frame 21, the air pump control module 12 can automatically detect the position of the plastic placement frame 31 and automatically turn on or off the air pump 25 according to the test requirements. The coordinated work of the air pump control module 12 and the air pump 25 enables the gas transportation process to be adjusted according to the test requirements. The gas flow limiting plate 15 and the gas guide vane 20 further optimize the gas flow direction and transportation intensity, ensuring that the plastic material can receive uniform impact force during the test. The damping effect of the telescopic damping rod 18 reduces the vibration and impact load of the driving rod 16 during movement, improving the stability and accuracy of the test.

[0046] In a possible implementation manner, a limiting plate 26 is provided above the plastic placement frame 31, and a hardness detection plate 28 is provided below the limiting plate 26.

The impact damage detector 30 contacts the surface of the plastic.

[0047] At the bottom of the inner wall of the first embedded frame 2, there is an impact damage detector control module 8. The impact damage detector control module 8 is electrically connected to the impact damage detector 30 through a transmission wire. The bottom of the plastic placement frame 31 contacts the impact damage detector control module 8, and the impact damage detector 30 is automatically turned on to work.

[0048] In the specific application of the embodiment of the present invention, a hardness detection plate 28 is provided below the limiting plate 26. The limiting plate 26 and the hardness detection plate 28 are connected by a tensile damping rod 27. The tensile damping rod 27 can effectively absorb the energy generated during the impact process and reduce the impact load on the hardness detection plate 28, thereby improving the stability and accuracy of the test. A plurality of groups of heat dissipation through holes 29 are opened on the bottom surface of the hardness detection plate 28. The heat dissipation through holes 29 can effectively dissipate the heat generated during the test and prevent the test results from being affected due to too high temperature. An impact damage detector 30 is provided between the plurality of groups of heat dissipation through holes 29. The impact damage detector 30 directly contacts the surface of the plastic and can detect the damage condition of the plastic during the impact process in real time and transmit the detection data to the impact damage detector control module 8.

[0049] At the bottom of the inner wall of the first embedded frame 2, there is an impact damage detector control module 8. The impact damage detector control module 8 is electrically connected to the impact damage detector 30 through a transmission wire to achieve precise control of the impact damage detector 30. The bottom of the plastic placement frame 31 contacts the impact damage detector control module 8. When the plastic placement frame 31 moves inside the working frame 21, the impact damage detector control module 8 can automatically detect the position of the plastic placement frame 31 and automatically turn on or off the impact damage detector 30 according to the test requirements. The collaborative work of the impact damage detector 30 and the impact damage detector control module 8 enables the damage situation of the plastic during the impact process to be detected and recorded in real time. The damping effect of the tensile damping rod 27 reduces the vibration and impact load of the hardness detection plate 28 during the impact process, improving the stability and accuracy of the test. The heat dissipation through holes 29 effectively dissipate the heat generated during the test to prevent the test results from being affected by excessive temperature. The design of the limiting plate 26 ensures the stability of the hardness detection plate 28 during the test and prevents it from being displaced due to excessive impact force.

[0050] In a possible implementation manner, a control panel 22 is provided on the outer wall of the working frame 21. The control panel 22 is electrically connected to the air pump 25 and the impact damage detector 30 through transmission wires respectively for control.

[0051] In the specific application of the embodiment of the present invention, the air pump 25 and the impact damage detector 30 adopted by the device are both mature existing technologies, and the working principles of the air pump 25 and the impact damage detector 30 are also well-known to those skilled in the art, so no more description will be given here.

[0052] When the present invention is specifically used, when the plastic material is placed inside the plastic placement frame 31, the device starts to run. The plastic placement frame 31 is located in the inner cavity of the working frame 21, and shock-absorbing damping rods 32 are provided around its bottom, which can effectively absorb the vibration and impact energy generated during the test to ensure the stability of the test. As the plastic material increases, the sliding connection block 4 moves inside the first installation frame 3 and the second installation frame 10, and drives the plastic placement frame 31 to perform displacement adjustment inside the working frame 21 through the connecting rod 5 to adapt to plastic materials of different weights.

[0053] Specifically, the test control component 1 includes a first embedded frame 2 and a second embedded frame 9, which are respectively provided with a hardness recording control module 7 and a hardness detection control module 11. When the plastic placement frame 31 moves, the sliding connection block 4 contacts the hardness recording control module 7, records the impact resistance performance data of the plastic, and transmits the data to the hardness detection control module 11 for analysis and processing.

[0054] Specifically, an air pump 25 is provided at the bottom of the working frame 21. The air pump 25 transports gas to the displacement driving assembly 13 through an air delivery pipe 14. The air pump control module 12 is provided at the bottom of the inner wall of the second embedded frame 9 and is electrically connected to the air pump 25 through a conducting wire. When the plastic placement frame 31 moves to a specific position, the air pump control module 12 automatically detects and activates the air pump 25. The displacement driving assembly 13 is located inside the air delivery pipe 14 and includes a gas flow limiting plate 15 and gas guiding vanes 20. Through the coordinated operation of the driving rod 16 and the sliding bearing sleeve 17 of the gas flow limiting plate 15, the gas guiding vanes 20 can guide the gas to flow along the length path of the driving rod 16. The arrangement of the gas guiding vanes 20 can determine the path and speed of the gas when flowing through. By reasonably arranging the gas guiding vanes 20, it is ensured that the gas distribution around the sliding bearing sleeve 17 is more uniform, thus avoiding the situation of excessive or too small local air flow.

[0055] With the operation of the displacement driving assembly 13, the gas guiding vanes 20 can dynamically adjust their positions as the sliding bearing sleeve 17 moves up and down on the outer wall of the driving rod 16, thereby achieving real-time control of the gas flow path. The change in gas intensity affects the impact force of the hardness detection plate 28 on the plastic sample. The gas flow limiting plate 15 restricts the flow intensity of the gas, and the gas guiding vanes 20 guide the flow direction of the gas. The two cooperate with each other to achieve control of the gas intensity.

[0056] The telescopic damping rods 18 are provided on both sides of the sliding bearing sleeve 17, which can reduce the vibration and impact load of the driving rod 16 during movement, improving the stability and accuracy of the test. The gas guiding vanes 20 further optimize the gas flow direction to ensure that the plastic material receives a uniform impact force during the test.

[0057] Specifically, a limiting plate 26 is provided above the plastic placement frame 31. The limiting plate 26 is connected to the hardness detection plate 28 through a tensile damping rod 27. The tensile damping rod 27 can absorb the energy generated during the impact process and reduce the impact load on the hardness detection plate 28. Heat dissipation through holes 29 are provided on the bottom surface of the hardness detection plate 28, which can effectively dissipate the heat generated during the test and prevent the test results from being affected due to excessive temperature. The impact damage detector 30 is provided between the heat dissipation through holes 29, directly contacting the plastic surface, and real-time detects the damage condition of the plastic during the impact process and transmits the detection data to the impact damage detector control module 8. The impact damage detector control module 8 is provided at the bottom of the inner wall of the first embedded frame 2 and is electrically connected to the impact damage detector 30 through a conducting wire to achieve automatic control of the impact damage detector 30.
