Description

Technical Field

[0001] This utility model relates to the field of compressive strength testing technology, and in particular to an intelligent compressive strength testing machine. Background Technology

[0002] Compression strength testing machines are mainly used to determine the physical properties of paperboard, such as ring crush strength, edge crush strength, adhesive peel strength, corrugated core flat crush strength, and flat crush strength of single-faced single-layer corrugated paperboard. This ensures the quality of packaging boxes made from the paperboard.

[0003] Chinese utility model patent CN219245177U discloses a paper compression strength testing machine, including a machine casing. Two columns are mounted on the top of the casing, and a crossbeam is mounted on top of each column. A test sensor is mounted below the crossbeam, and an upper pressure plate is mounted below the test sensor. A lower pressure plate is located below the upper pressure plate, and a monitoring sensor is mounted at the bottom of the lower pressure plate. The monitoring sensor is mounted on the top of a lifting pressure column on the machine casing. When the upper and lower pressure plates compress the cardboard in between, the measured values ​​from the test sensor on the upper pressure plate and the monitoring sensor under the lower pressure plate should be similar or the same. If they are different, it indicates a test error or mistake.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device determines the accuracy of the measurement results by comparing the similarity or identicality of the measured values ​​from the test sensor and the monitoring sensor. However, in the initial state, due to gravity, the upper pressure plate exerts a downward pull on the test sensor. When the lower pressure plate rises and the cardboard contacts the upper pressure plate, the upper pressure plate is supported, and its weight is transferred to the lower pressure plate and the monitoring sensor, resulting in a significant difference between the readings of the test sensor and the monitoring sensor. Furthermore, the cardboard is placed on the lower pressure plate, and its weight directly acts on the lower pressure plate; differences in the density and mass of the cardboard also affect the measurement results of the monitoring sensor. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an intelligent compressive strength testing machine, including a frame, a first mounting platform and a second mounting platform are horizontally spaced at the top of the frame, an electric push rod is horizontally arranged on the side of the first mounting platform away from the second mounting platform, the piston rod of the electric push rod passes through the second mounting platform and is provided with a movable seat, pressure sensors are provided on the side of the movable seat adjacent to the second mounting platform, pressure plates are provided on the side of the two pressure sensors adjacent to each other, a sliding seat is horizontally slidably arranged on the top of the frame between the two pressure plates, a placement plate is provided on the sliding seat, and a clamping assembly is provided on the placement plate.

[0007] By adopting the above technical solution, a frame, a first mounting platform, a second mounting platform, a movable seat, pressure sensors, a sliding seat, and a clamping assembly are set up. The cardboard is placed vertically on the placement platform and then clamped and fixed by the clamping assembly. During placement, ensure that both sides of the cardboard extend beyond the top of the placement platform so that both pressure plates can contact the cardboard. Then, slide the sliding seat so that one side of the cardboard contacts the pressure plate on the second mounting platform. The movable seat is moved by an electric push rod, causing the pressure sensor and pressure plate on it to move synchronously, thereby applying pressure to the cardboard. The two pressure sensors record the corresponding values ​​and detect whether these values ​​are similar or the same; similar or the same values ​​are considered valid data. If the values ​​differ too much, it indicates that an error or mistake has occurred in the test, and such data will not be included, thus avoiding losses caused by test errors or mistakes of the compression strength tester and effectively improving the accuracy of the test. In the initial state, the two pressure sensors and pressure plates are in the same state, and the weight of the cardboard is borne by the placement platform, ensuring the accuracy of the values ​​detected by the two pressure sensors.

[0008] Furthermore, the bottom of the placement plate is provided with two upright plates spaced apart. The bottom of the upright plates is connected to the sliding seat. Two strip holes are symmetrically opened on the placement plate. The clamping assembly includes a sliding block slidably disposed in the strip hole. A clamping plate is vertically disposed on the top of the sliding block. A bidirectional threaded rod is horizontally rotatably disposed between the two upright plates. The two sliding blocks are respectively spirally connected to both ends of the bidirectional threaded rod through threaded holes. A handle is disposed at one end of the bidirectional threaded rod passing through the upright plate.

[0010] Furthermore, a guide rod is provided between the two upright plates, and a guide hole is provided on the sliding block, the guide hole being slidably connected to the guide rod.

[0011] By adopting the above technical solution, guide rods and guide holes are set to ensure the stability of the sliding block, thereby ensuring the stability of the clamping plate.

[0012] Furthermore, the upper side of the placement plate is higher than the lower side edge of the pressure plate.

[0013] By adopting the above technical solution, the upper side of the placement plate is set higher than the lower edge of the pressure plate, so that the side of the cardboard is completely located within the area of ​​the pressure plate surface.

[0014] Furthermore, two slide rails are spaced apart on the top of the frame, the length direction of the slide rails is consistent with the length direction of the electric push rod, and the sliding seat is slidably connected to the slide rails through a slider.

[0015] By adopting the above technical solution and setting up slide rails and sliders, the stability of the sliding seat is ensured.

[0016] Furthermore, the length direction of the bidirectional threaded rod is perpendicular to the length direction of the slide rail.

[0017] Furthermore, the sides of the clamping plate and the placement plate adjacent to the pressure plate are coplanar.

[0018] By adopting the above technical solution, the clamping plate and the placement plate are set to be coplanar with the sides of the adjacent pressing plate, ensuring that the pressing plate only contacts the cardboard and does not contact the sides of the clamping plate and the placement plate, thus ensuring the accuracy of the measurement results.

[0020] 1. In this application, a frame, a first mounting platform, a second mounting platform, a movable seat, a pressure sensor, a sliding seat, and a clamping assembly are provided. The cardboard is placed vertically on the placement platform and then clamped and fixed by the clamping assembly. During placement, it is ensured that both sides of the cardboard extend beyond the top of the placement platform so that both pressure plates can contact the cardboard. Then, the sliding seat is slid so that one side of the cardboard contacts the pressure plate on the second mounting platform. The movable seat is moved by an electric push rod, causing the pressure sensor and pressure plate on it to move synchronously, thereby applying pressure to the cardboard. The two pressure sensors record corresponding values ​​and detect whether these values ​​are similar or the same; similar or the same values ​​are considered valid data. If the value difference is too large, it indicates that an error or mistake has occurred in the test, and such data will not be included, thereby avoiding losses caused by test errors or mistakes of the compression strength tester and effectively improving the accuracy of the test. In the initial state, the two pressure sensors and pressure plates are in the same state, and the weight of the cardboard is borne by the placement platform, ensuring the accuracy of the values ​​detected by the two pressure sensors.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-2As shown in the illustration, this application discloses an intelligent compression strength testing machine, including a frame 10, a first mounting platform 20, a second mounting platform 30, and a clamping assembly 70. The first mounting platform 20 and the second mounting platform 30 are horizontally spaced at the top of the frame 10. An electric push rod 21 is horizontally arranged on the side of the first mounting platform 20 away from the second mounting platform 30. A through hole is provided on the first mounting platform 20, through which the piston rod of the electric push rod 21 passes and is provided with a movable seat 22. Pressure sensors 40 are horizontally arranged on the side of the movable seat 22 adjacent to the second mounting platform 30, and pressure plates 41 are arranged on the side of the two pressure sensors 40 adjacent to each other. A sliding seat 50 is horizontally slidably arranged on the top of the frame 10 between the two pressure plates 41. The sliding direction of the sliding seat 50 is consistent with the length direction of the electric push rod 21. A placement plate 60 is provided on the sliding seat 50, and the clamping assembly 70 is arranged on the placement plate 60 for clamping and fixing the cardboard on the placement plate 60. During the cardboard compression strength test, the cardboard is first placed vertically on the placement plate 60, and then clamped and fixed by the clamping assembly 70. During placement, ensure that both sides of the cardboard extend beyond the top of the placement plate 60 so that both pressure plates 41 can contact the cardboard. Then, slide the sliding seat 50 so that one side of the cardboard contacts the pressure plate 41 on the second mounting platform 30. The electric push rod 21 drives the moving seat 22, causing the pressure sensor 40 and pressure plate 41 on it to move synchronously, thereby applying pressure to the cardboard. The two pressure sensors 40 record corresponding values ​​and check whether these values ​​are similar or identical; similar or identical values ​​are considered valid data. If the values ​​differ too much, it indicates an error or mistake in the test, and such data will not be counted, thus avoiding losses due to test errors or mistakes in the compression strength tester and effectively improving the accuracy of the test. In the initial state, the two pressure sensors 40 and pressure plate 41 are in the same state, and the weight of the cardboard is borne by the placement plate 60, ensuring the accuracy of the values ​​detected by the two pressure sensors 40.

[0027] Specifically, two upright plates 61 are spaced apart at the bottom of the placement plate 60. The bottom of the upright plates 61 are connected to the sliding seat 50 to ensure the stability of the placement plate 60 during installation. Two strip holes 62 are symmetrically opened on the placement plate 60, with the length direction of the strip holes 62 aligned with the length direction of the placement plate 60. The clamping assembly 70 includes sliding blocks 71 slidably disposed within the strip holes 62. A clamping plate 72 is vertically disposed on the top of the sliding block 71. A bidirectional threaded rod 73 is horizontally rotatably disposed between the two upright plates 61. The two sliding blocks 71 are respectively screwed to both ends of the bidirectional threaded rod 73 through threaded holes. When the bidirectional threaded rod 73 rotates, the two sliding blocks 71 move synchronously toward the center of the placement plate 60 or synchronously away from the center of the placement plate 60, thereby clamping or releasing the cardboard. One end of the bidirectional threaded rod 73 passes through the upright plate 61 and is provided with a handle 74. Rotating the handle 74 drives the bidirectional threaded rod 73 to rotate. A guide rod 63 is provided between the two upright plates 61, and a guide hole is provided on the sliding block 71. The guide hole is slidably connected to the guide rod 63 to ensure the stability of the sliding block 71, thereby ensuring the stability of the clamping plate 72.

[0028] During setup, the upper side of the placement plate 60 is higher than the lower edge of the pressure plate 41, ensuring that the side of the cardboard is completely within the area of ​​the pressure plate 41. The sides of the clamping plate 72 and the placement plate 60 adjacent to the same pressure plate 41 are coplanar, ensuring that the pressure plate 41 only contacts the cardboard and not the sides of the clamping plate 72 or the placement plate 60, thus guaranteeing accurate measurement results. Two slide rails 11 are spaced apart at the top of the frame 10. The length direction of the bidirectional threaded rod 73 is perpendicular to the length direction of the slide rail 11, and the length direction of the slide rail 11 is consistent with the length direction of the electric push rod 21. The sliding seat 50 is slidably connected to the slide rail 11 via a slider, ensuring the stability of the sliding seat 50. Stops are provided on both sides of the slide rail 11 at the top of the frame 10 to prevent the sliding seat 50 from slipping off the slide rail 11.

[0029] The operating principle of the intelligent compression strength tester in this embodiment is as follows: The cardboard is placed vertically on the placement plate 60. Then, the handle 74 is rotated to drive the bidirectional threaded rod 73 to rotate, causing the two sliding blocks 71 to move synchronously towards the center of the placement plate 60, and thus driving the clamping plate 72 to move and clamp the cardboard. Then, the sliding seat 50 is slid so that one side of the cardboard contacts the pressure plate 41 on the second mounting platform 30. The electric push rod 21 is activated to drive the moving seat 22 to move, causing the pressure sensor 40 and the pressure plate 41 on it to move synchronously, thereby applying pressure to the cardboard. The two pressure sensors 40 record the corresponding values ​​and detect whether these values ​​are similar or the same. If they are similar or the same, they are considered valid data. If the value difference is too large, it indicates that an error or mistake has occurred in the test. Such data will not be included, effectively improving the accuracy of the test.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
