[0002] With the development of e-commerce, cardboard boxes, as a major form of logistics packaging, are frequently subjected to external pressure during transportation, leading to deformation or damage. The compression resistance of cardboard boxes is a key indicator of their quality; therefore, compression resistance testing is typically performed after production. However, commercially available testing machines for cardboard box compression resistance often use a pressure plate that moves up and down to apply pressure to the boxes on the testing platform. Most of these pressure plates have a certain span, which, while suitable for testing boxes of different sizes, is easily affected by the box's placement. Furthermore, the often centrally positioned pressure detection components on the pressure plate can lead to uneven stress, increasing the probability of deformation or even damage to the pressure plate and reducing the stability and accuracy of the testing process.

At the same time, it further improves the uniformity of force on the pressure plate that presses the cardboard box during the testing process, improves the testing effect and accuracy of the corresponding test results for cardboard boxes of corresponding sizes, and has a certain degree of flexibility and applicability.
[0004] The technical solution adopted by this utility model to solve the above problems is:
[0005] A cardboard box compression resistance testing device includes a frame and a test platform mounted on it, and a main body of a testing machine for testing the compression resistance of cardboard boxes. The main body is a pressure plate, which is driven up and down by a drive component inside a cabinet located on top of the frame and connected to a pressure detection assembly. Multiple sets of second pressure detection assemblies are arranged around the corners of the pressure plate. Two sets of first and second sliding rods are respectively installed along the horizontal and vertical directions of the pressure plate, with two sets of first and second sliding blocks slidably mounted at their ends. The two ends of the second sliding rods act on the first sliding blocks slidably mounted between the two sets of first sliding rods. Locking components are provided on both the first and second sliding blocks. The second pressure detection assemblies are mounted on the second sliding blocks. The pressure plate is connected to the drive component via a connecting seat, and the pressure detection assemblies act on the connecting seat. A second pressure plate for pressing down by multiple sets of second pressure detection assemblies is slidably mounted on the connecting seat, and an adjusting component is provided at the connection position with the second pressure plate.
[0006] Preferably, the second pressure plate is provided as two sets of plates and can be detachably installed on the connecting seat through a plug-in structure provided on one side of the plates.
[0007] Preferably, the corresponding plates of the pressure plate and the second pressure plate are provided with observation windows of appropriate size.
[0008] Preferably, the corresponding rods of the first and second slide rods are marked with scale lines of appropriate length.

[0014] Compared with the prior art, this utility model has the following advantages and effects:
[0015] This utility model relates to a cardboard box compression resistance testing device. Compared to traditional testing machine structures, the overall structure of this testing machine, driven by a drive component, allows for compression resistance testing of cardboard boxes of different sizes. Simultaneously, a second pressure detection component on the pressure plate, along with corresponding structures on the first and second slide rods via first and second sliders, is added and arranged. When the pressure plate presses down on the cardboard box, multiple sets of second pressure detection components, corresponding to the four corners of the cardboard box, detect the corresponding pressure magnitude and values based on the box's size. This determines the force exerted on the pressure plate at different positions on the test bench. When the pressure values detected by multiple sets of second pressure detection components are essentially consistent, the optimal testing effect for compression resistance testing of the cardboard box at the optimal position is achieved. Furthermore, the synchronous detection process of the pressure detection components on the connecting seat and multiple sets of second pressure detection components on the second sliders further expands the compression resistance testing effect of the pressure plate on the cardboard box. The pressure detection range is wide, and the process of judging the pressure values detected by multiple sets of second pressure detection components ensures the uniformity of force on the pressure plate during the test, thereby further improving the test effect and accuracy of the test results of this type of testing machine for the compression resistance test of cartons. In addition, the second pressure plate is also provided with a through groove, which facilitates the wiring connection and arrangement of the second pressure detection components. At the same time, when the pressure detection components acting on the pressure plate and the second pressure detection components are performing pressure detection at different positions and under corresponding conditions during the compression resistance test of the carton, when the pressure detection value fluctuates within a certain range, a signal can be transmitted to the operation panel on the cabinet, so that the drive component can drive the pressure plate to move upward and separate from the carton. An alarm status is displayed by an indicator light connected to one side of the cabinet, which is convenient for the operator to check the status and make timely adjustments. This can effectively reduce the degree of further deformation or even damage to the pressure plate or even the second pressure plate, and improve the testing stability, usage flexibility and applicability of this type of testing machine.

Detailed Implementation
[0022] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0023] See Figure 1-3This embodiment relates to a carton compression resistance testing device, comprising a frame 1, a test platform 11 mounted thereon, and a pressure plate 3, which is driven up and down by a drive component 121 located inside a cabinet 12 on the top of the frame 1 and connected to a pressure detection component 2, forming a main body for testing the compression resistance of cartons. Multiple sets of second pressure detection components 4 are also arranged around the corners of the pressure plate 3. Two sets of first sliding rods 5 and second sliding rods 6 are respectively installed along the horizontal and vertical directions of the pressure plate 3, and two sets of first sliders 51 are slidably mounted at both ends of each first sliding rod 51. The second slider 61 and the second slider rod 6 are both connected to the first slider 51 which is slidably disposed between the two sets of first slider rods 5. The first slider 51 and the second slider 61 are both provided with locking members 7. The second pressure detection component 4 is installed on the second slider 61. The pressure plate 3 is connected to the driving component 121 through the connecting seat 31 provided thereon, and the pressure detection component 2 acts on the connecting seat 31. The connecting seat 31 is slidably disposed with a second pressure plate 3 for pressing multiple sets of second pressure detection components 4, and an adjusting member 311 is provided at the connection position with the second pressure plate 3.
[0024] Specifically in this embodiment, such as Figure 1 The overall structural design of the main body of this testing machine for testing the compression resistance of cartons, as shown below, can be referenced in actual use. Figure 2 and Figure 3 As shown, the carton is pre-placed on the test bench 11. Simultaneously, the positions of multiple sets of second pressure detection components 4 on the pressure plate 3 are adjusted according to the carton's placement on the test bench 11 and its corresponding size. The pressure detection components 2 are adapted to the corresponding elements on the pressure plate 3 of a commercially available testing machine for testing the compression resistance of cartons. The second pressure detection components 4 are conventionally designed... Figure 2 and Figure 3Taking the pressure sensor as an example, the structure is set accordingly, which can then push the first slider 51 on the first slide rod 5 and the second slider 61 on the second slide rod 6 to slide along the horizontal and vertical directions of the pressure plate 3, so that the second pressure detection component 4 installed on the second slider 61 can correspond to the four corner edges of the carton placed on the test table 11 below the pressure plate 3. At the same time, by rotating the locking piece 7 with the bolt connection 93 structure on the first slider 51 and the second slider 61, the corresponding rod positions of the first slide rod 5 and the second slide rod 6 are locked, completing the position adjustment process of the second pressure detection component 4. Then, by rotating the bolt connection 93 structure and rotating it on the connecting seat 3 through the thread structure, the second pressure detection component 4 can be adjusted. The adjusting component 311 on the second slider 61 can adjust the height of the second pressure plate 3 above the pressure plate 3 and lock it at the corresponding height. Specifically, when the upper and lower ends of the second pressure detection component 4 on the second slider 61 can respectively fit with the second pressure plate 3, the position of the second pressure plate 3 is locked according to the pressure detected by the second pressure detection component 4 in the corresponding state, and the zeroing process of the second pressure detection component 4 is performed. This completes the preparatory work for the compression resistance test of the carton of the corresponding size. Finally, through the controller 122 and operation buttons 123 installed inside the cabinet 12 at the top of the frame 1, the real-time status of the pressure detection component 2 and the second pressure detection component 4 can be observed and adjusted, and at the same time, it enables... Figure 2Taking the example of a test machine, the driving component 121, with its cylinder structure, operates, driving the pressure plate 3 downwards to press the top of the carton placed above the test platform 11. The pressure detection component 2 acting on the connecting seat 31 and the second pressure detection component 4 on the second slider 61 can detect the pressure at corresponding positions on the pressure plate 3 in real time, thereby realizing the test process of the carton compression resistance of this test machine body. Compared with the traditional test machine structure, the overall structure of this test machine body for carton compression resistance testing, through the driving component 121 driving the pressure plate 3 and its pressure detection component 2, can perform compression resistance testing on cartons of different sizes. At the same time, the second pressure detection component 4 on the pressure plate 3 and its corresponding structure added and arranged on the first slider 5 and the second slider 6 through the first slider 51 and the second slider 6 respectively, are set up according to the size of the carton when the pressure plate 3 presses the carton. Multiple sets of second pressure detection components are set on the pressure plate 3 corresponding to the four corners of the carton. The pressure detection component 4 performs a corresponding pressure detection process and obtains the corresponding pressure value. It determines the force on different positions of the pressure plate 3 when the carton on the test platform 11 is pressed down by the pressure plate 3. When the pressure values detected by multiple sets of second pressure detection components 4 are basically consistent, the optimal detection effect for testing the compression resistance of the carton at the optimal position can be achieved. Therefore, combined with the synchronous detection process of the pressure detection component 2 on the connecting seat 31 and the multiple sets of second pressure detection components 4 on the multiple sets of second sliders 61, the pressure detection range during the pressing process of the pressure plate 3 on the carton can be further expanded. By judging the pressure values detected by multiple sets of second pressure detection components 4, the uniformity of force on the pressure plate 3 during the test is ensured, thereby further improving the testing effect and accuracy of the test results of this testing machine for the compression resistance test of cartons. In addition, the second pressure plate 3 is also provided with a through groove 91. The addition of the through groove 91 facilitates the wiring connection and arrangement of the second pressure detection components 4. At the same time, the pressure detection components 2 and the second pressure detection components 4 acting on the pressure plate 3 are in different positions during the compression resistance test of the cartons by the pressure plate 3. During the pressure test under the corresponding conditions, when the pressure test value fluctuates within a certain range, a signal is transmitted to the controller 122 installed on the cabinet 12, so that the drive component 121 can drive the pressure plate 3 to move upward and separate from the carton. The alarm status is displayed by the indicator light 124 connected to one side of the cabinet 12, which makes it convenient for operators to check the status and make timely adjustments. This can effectively reduce the degree of further deformation or even damage to the pressure plate 3 or even the second pressure plate 3, and improve the testing stability, usage flexibility and applicability of this testing machine.
[0025] The second pressure plate 3 is configured as two sets of plates 90 and can be detachably mounted on the connecting seat 31 via a plug-in structure 92 provided on one side of the plates 90. See details for further information. Figure 4 The two sets of plates 90 and their corresponding insertion structures 92 on the second pressure plate 3 are shown. The two sets of plates 90 can be connected to the corresponding positions of the second pressure plate 3 and the connecting seat 31 by means of the bolts 93 rotatably provided on the insertion structure 92. This can further improve the portability and efficiency of the operation of the multiple sets of second pressure detection components 4 on the lower pressure plate 3 during the position adjustment process. In addition, the structural settings of the two sets of plates 90 in the second pressure plate 3 have a certain degree of uniformity and universality, which can further improve the speed of operation during the installation process.
[0026] Both the pressure plate 3 and the corresponding plate body 90 of the second pressure plate 3 are provided with observation windows 100 of appropriate size, specifically from... Figure 3 and Figure 4 As can be seen, the opening of the observation window 100 on the pressure plate 3 and the second pressure plate 3 can be used according to the usage requirements. The observation window 100 is made of a plate 90 made of transparent materials such as glass or acrylic sheet. Under the premise of ensuring stable support of the second pressure detection component 4, the visibility range of the corresponding plate 90 can be further improved. This facilitates operation and further improves the speed and accuracy of adjustment of the second pressure detection component 4 and the corresponding positions of the four corners of the carton below the pressure plate 3, thereby further improving the testing effect and accuracy of the cardboard.
[0027] The first slide bar 5 and the second slide bar 6 are both marked with scale lines 8 of appropriate length. The scale lines 8 can be marked according to the size of a regular carton, which can further improve the speed of the second pressure detection component 4 in the position adjustment process and the consistency of the corresponding position in the corresponding direction, and improve the operational flexibility.
[0028] A suitable compression spring 312 is also fitted onto the connecting seat 31 located below the second pressure plate 3, from... Figure 4 As can be seen, the addition of the compression spring 312 can further improve the speed and ease of operation of adjusting the height of the second pressure plate 3 on the connecting seat 31 via the adjusting member 311.
[0029] A second connecting seat 53 is installed on the second slider 61. The second connecting seat 53 includes a first seat 621 fixed on the second slider 61 and a second seat 622 for fixing the second pressure detection component 4. The second seat 622 is slidably disposed on the first seat 621, and a second compression spring 623 of appropriate size is sleeved around the second pressure detection component 4 between the first seat 621 and the second seat 622. When the second pressure detection component 4 fixed on the second seat 622 is pressed against the pressure plate 3 above, it can pass through the protrusion 6221 provided at the corresponding position of the second seat 622 and the second pressure spring 623 under the action of the second compression spring 623. A slide rail 6211 is provided at a corresponding position on the first body 621 to accommodate the sliding of the protrusion 6221, so as to realize the up and down sliding process of the second body 622 and the second pressure detection component 4 on the first body 621. At the same time, when the bottom of the second pressure detection component 4 is in contact with the base plate during the sliding process, the second pressure plate 3 on the connecting seat 31 is locked in position. The addition of the structure of the second connecting seat 53 can further improve the convenience of the second pressure plate 3 in adjusting the position of the second pressure detection component 4 and judging the corresponding position. In addition, the connection method between the second connecting seat 53 and the second slider 61 also facilitates the installation, disassembly and replacement of the second pressure detection component 4.
[0030] The first slide rod 5 and the first slider 51 slidably mounted on it are detachably connected by multiple sets of second locking members 52 rotatably mounted at both ends of the first slide rod 5, and are detachably mounted on the pressure plate 3 by a third connecting seat 31 positioned between the second locking members 52. See details [link to relevant documentation]. Figure 5 As shown, the second locking member 52, which adopts a bolted connection 93 structure, has a corresponding connection method with the first slide rod 5 having a matching threaded structure at both ends, and a detachable connection method with the third connecting seat 31 that locks the position at both ends of the first slide rod 5 through the second locking member 52. The first slide rod 5 and the second slide rod 6 connected to it through the first slider 51 can be easily installed and removed from the pressure plate 3 through the third connecting seat 31. At the same time, the second locking member 52 facilitates the installation and removal of the first slider 51 on the first slide rod 5. In addition, the detachable connection structure with the threaded connection between the two ends of the second slide rod 6 and the first slider 51 also facilitates the installation and removal of the second slide rod 6 and the second slider 61 on it, further improving the structural detachability and disassembly flexibility of this carton compression resistance testing equipment.
[0031] The test bench 11, located below the pressure plate 3, is slidably mounted on the frame 1 via multiple sets of third locking components 111 rotatably mounted on both sides and multiple sets of sliding grooves 13 on the corresponding frame of the frame 1 at the connection position with the third locking components 111. For details, please refer to [link to relevant documentation]. Figure 1As shown, the test platform 11 can be rotatably equipped with multiple sets of third locking members 111 with bolted connection 93 structure, and can be adjusted in height and locked at the corresponding height during the sliding process along multiple sets of sliding grooves 13 opened on the frame 1. This can further improve the adjustable range of the distance between the test platform 11 and the upper pressure plate 3, meet the testing process of cartons of different sizes, and improve the structural flexibility and applicability of this testing machine.
[0032] The frame of the machine frame 1 located on both sides of the slide 13 is also marked with a second scale line 131 adapted to the length of the slide 13. The marking of the second scale line 131 on the frame of the machine frame 1 located on both sides of the slide 13 can further improve the operation speed and position correspondence accuracy and uniformity of the test table 11 during the position adjustment process, and reduce unnecessary impact on the test results.
