Description

Technical Field

[0001] This invention relates to the field of non-metallic membrane testing technology, specifically to a non-metallic membrane composite material performance testing workbench. Background Technology

[0002] Non-metallic membrane composite materials are widely used in industrial fields such as packaging, construction, electronics and new energy. Their impact resistance is one of the key indicators for evaluating the reliability and service life of materials. In actual use, these materials are often subjected to instantaneous impact loads, so it is usually necessary to determine their puncture resistance and tear resistance through dart impact tests.

[0003] Currently, traditional dart impact testers typically have only one set of test stations, and can only install a single sample for testing at a time. When multiple samples need to be tested continuously, it is necessary to repeatedly stop the machine, disassemble the tested sample, and install a new sample. The operation is cumbersome and time-consuming. At the same time, due to the lack of an effective film tensioning structure when clamping the sample, the accuracy and reliability of the test results are easily affected by the loosening of the film surface. Summary of the Invention

[0004] The purpose of this invention is to provide a non-metallic membrane composite material performance testing workbench with multiple testing stations, which allows personnel to switch between multiple samples during testing, improving the efficiency of the testing operation. At the same time, it can effectively adjust the tension of the samples, avoiding the impact of sample looseness on the accuracy of the test.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a performance testing workbench for non-metallic membrane composite materials, comprising a platform body, a column fixedly installed at the middle of the top of the platform body, a dart holder fixedly installed at the upper end of the column, a positioning sleeve fixedly installed at the bottom of the dart holder, a test dart head fitted at the lower end of the inner cavity of the positioning sleeve, an electromagnet fixedly installed at the upper end of the inner cavity of the positioning sleeve, the top of the test dart head being attracted to the bottom of the electromagnet, a groove provided at the top of the platform body, a guide block fixedly installed at the right end of the groove, and a test dart head movably connected to the lower end of the column via a bearing. The test platform has three clamping seats fixedly installed on its top. Each clamping seat has a wing bolt threaded to both ends. A pressure cap is movably inserted between the surfaces of two wing bolts. An annular groove is provided at the bottom of the pressure cap. Vertical shafts are slidably connected to the four sides of the bottom of the clamping seats. An annular pressure rod is fixedly installed between the tops of the four vertical shafts. A fixing frame is fixedly installed between the bottoms of the four vertical shafts. A support column is fixedly installed at the middle of the bottom of the fixing frame. A movable ball is embedded at the bottom of the support column. The bottom of the movable ball is slidably connected to the surface of the groove.

[0006] As a preferred embodiment, the side of the test platform is fixedly connected with three pin seats, and the surface of each pin seat is provided with a pin hole.

[0007] As a preferred embodiment, a receiving cavity is provided on the right side of the platform, a second spring is fixedly installed at the left end of the bottom of the receiving cavity, a pressing rod is fixedly installed at the top of the second spring, a pin is fixedly installed at the left end of the top of the pressing rod, and the surface of the pin is slidably connected to the right end of the top of the platform.

[0008] As a preferred embodiment, a guide rod is fixedly installed at the right end of the receiving cavity, and the middle end of the pressing rod is slidably connected to the surface of the guide rod.

[0009] As a preferred embodiment, an annular support is fixedly installed around the top of the test platform, and guide balls are movably connected between the inner cavity of the annular support and the surface of the test platform.

[0010] As a preferred embodiment, a first spring is sleeved on the lower end of the vertical shaft, and the top of the first spring is fixedly installed on the bottom of the clamping seat.

[0011] As a preferred embodiment, a protective baffle is fixedly installed on the top of the test bench. There are three protective baffles, and a stabilizing sleeve is fixedly installed between the upper ends of the three protective baffles. The inner cavity of the stabilizing sleeve is fitted onto the lower end of the column.

[0012] As a preferred embodiment, a controller is fixedly installed at the middle end of the column, and the controller is electrically connected to an electromagnet.

[0013] As a preferred embodiment, the top of the clamping seat is provided with a receiving groove, and the surface of the annular pressure rod is slidably connected to the surface of the receiving groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the arrangement of multiple clamping seats, wing bolts, and pressure caps, facilitates the clamping and fixing of multiple sets of thin film samples during testing. Simultaneously, the rotation of the testing platform allows for the sequential switching of multiple workstations to the testing area, enabling continuous multi-station testing and significantly improving testing efficiency. Furthermore, through the coordinated action of the groove, guide block, movable ball bearing, support column, fixing frame, vertical shaft, annular pressure bar, and annular groove, when a set of thin film samples rotates to the testing area, the movable ball bearing at that position is pushed upwards by the inclined surface of the guide block. This movement drives the support column, fixing frame, vertical shaft, and annular pressure bar to move, causing the annular pressure bar to lift the perimeter of the thin film sample and protrude into the annular groove at the bottom of the pressure cap. This automatically tensions the surface of the thin film sample, preventing loosening or wrinkling and ensuring the accuracy of the impact test. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0019] Example 1: Please see Figures 1-6As shown, this invention provides a performance testing workbench for non-metallic membrane composite materials, including a platform body 1. A column 2 is fixedly installed at the middle of the top of the platform body 1. A dropper seat 3 is fixedly installed at the upper end of the column 2. A positioning sleeve 9 is fixedly installed at the bottom of the dropper seat 3. A test dart head 11 is fitted onto the lower end of the inner cavity of the positioning sleeve 9. An electromagnet 10 is fixedly installed at the upper end of the inner cavity of the positioning sleeve 9. The top of the test dart head 11 is attracted to the bottom of the electromagnet 10. A groove 14 is provided on the top of the platform body 1. A guide block 15 is fixedly installed at the right end of the groove 14. A test platform 6 is movably connected to the lower end of the column 2 via a bearing. The top of the test platform 6 is fixedly... Three clamping seats 8 are fixedly installed. Both ends of the clamping seats 8 are threaded with wing bolts 31. A pressure cap 16 is movably inserted between the surfaces of two wing bolts 31. An annular groove 22 is provided at the bottom of the pressure cap 16. Vertical shafts 20 are slidably connected to the four sides of the bottom of the clamping seats 8. An annular pressure rod 24 is fixedly installed between the tops of the four vertical shafts 20. A fixing frame 17 is fixedly installed between the bottoms of the four vertical shafts 20. A support column 18 is fixedly installed at the middle of the bottom of the fixing frame 17. A movable ball 19 is embedded in the bottom of the support column 18. The bottom of the movable ball 19 is slidably connected to the surface of the groove 14.

[0020] In this technical solution, when it is necessary to test the impact resistance of non-metallic film composite materials, the operator can first place multiple sets of film samples on the top of three clamping seats 8 respectively. By tightening the wing bolts 31 on both sides, the pressure cap 16 is moved downward, thereby pressing the edge of the sample between the pressure cap 16 and the clamping seat 8 to achieve sample clamping and fixing. After the sample is installed, the test platform 6 is pushed by hand to rotate around the column 2, so that one of the clamping seats 8 and the sample rotate to directly below the test dart head 11. During the rotation of the test platform 6, the movable ball 19 at the bottom of the column 18 can roll along the groove 14 on the surface of the platform 1. When the station is rotated to the test position, the movable ball 19 will contact the inclined surface of the guide block 15 at the right end of the groove 14 and move upward along the inclined surface. The movable ball 19 moves and carries... The moving support 18, the fixed frame 17, the vertical shaft 20, and the annular pressure bar 24 move upward as a whole, causing the annular pressure bar 24 to lift the perimeter of the thin film sample during its movement and protrude into the annular groove 22 at the bottom of the pressure cap 16. This process causes the sample surface to automatically tighten, avoiding the impact test accuracy caused by looseness or wrinkles. During the test, the electromagnet 10 is disconnected, causing the magnetic attraction to the test dart head 11 to disappear. The test dart head 11 falls freely under the action of gravity, impacting the tightened thin film sample below, completing one impact test. After a set of samples is tested, the operator can rotate the test table 6 again to move the next sample to the test position. This cycle can be repeated to achieve continuous and rapid testing of multiple samples, effectively improving the efficiency and accuracy of the testing operation.

[0021] Example 2: Based on Embodiment 1, the present invention is as follows: Figure 1 and Figure 6 As shown, the test platform 6 is fixedly connected to the side with three pin seats 7. The surface of the pin seat 7 is provided with pin holes. The right side of the platform body 1 is provided with a receiving cavity 26. The left end of the bottom of the receiving cavity 26 is fixedly installed with a second spring 27. The top of the second spring 27 is fixedly installed with a pressing rod 29. The left end of the top of the pressing rod 29 is fixedly installed with a pin 30. The surface of the pin 30 is slidably connected to the right end of the top of the platform body 1. The right end of the receiving cavity 26 is fixedly installed with a guide vertical rod 28. The middle end of the pressing rod 29 is slidably connected to the surface of the guide vertical rod 28.

[0022] In this technical solution, through the setting of pin seat 7, pin hole, pressing rod 29, second spring 27 and pin 30, during the switching of test positions, the operator can press down the pressing rod 29 to drive the pin 30 to move and compress the second spring 27. When the switching operation is completed, by stopping the pressing of the pressing rod 29 and pushing under the tension of the second spring 27, the pin 30 can be inserted into the pin hole of the corresponding pin seat 7, which can effectively lock and limit the test table 6, prevent the test table 6 from rotating and deviating, and ensure that the test operation can be carried out normally. Through the setting of the guide rod 28, the pressing rod 29 is guided to avoid tilting and deviating during the movement of the pressing rod 29.

[0023] Example 3: Based on Embodiment 1, the present invention is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an annular support 5 is fixedly installed around the top of the platform 1. A guide ball 25 is movably connected between the inner cavity of the annular support 5 and the surface of the test platform 6. A first spring 21 is sleeved on the lower end of the vertical shaft 20. The top of the first spring 21 is fixedly installed on the bottom of the clamping seat 8. A protective baffle 13 is fixedly installed on the top of the test platform 6. There are three protective baffles 13. A stabilizing sleeve 12 is fixedly installed between the upper ends of the three protective baffles 13. The inner cavity of the stabilizing sleeve 12 is sleeved on the lower end of the column 2. A controller 4 is fixedly installed in the middle of the column 2. The controller 4 is electrically connected to the electromagnet 10. A receiving groove 23 is provided on the top of the clamping seat 8. The surface of the annular pressure rod 24 is slidably connected to the surface of the receiving groove 23.

[0024] In this technical solution, the ring support 5 and guide ball bearings 25 are used to support and guide the test platform 6 from all sides, preventing the test platform 6 from tilting or shifting due to force. The first spring 21 provides elastic support between the vertical shaft 20 and the clamping seat 8, so that the vertical shaft 20 can be moved and reset later. The protective baffle 13 provides protection between two adjacent workstations. The stabilizing sleeve 12 strengthens and fixes the upper end of the protective baffle 13. The controller 4 allows personnel to operate the electromagnet 10 during the test operation. The receiving groove 23 accommodates the ring pressure rod 24 at the top of the clamping seat 8.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
