A square packaging carton has eight hanging corners, and each hanging corner has three areas and a convergence point. During use, the hanging corners of a square packaging carton are the most vulnerable to bumps. Therefore, manufacturers need to conduct compressive capacity tests on the hanging corners of the produced square packaging cartons.

However, when the existing compressive capacity testing devices for the hanging corners of square cartons are in use, they usually conduct compressive tests on a single area of the hanging corners of a square carton, and cannot more realistically simulate the complex working environment of a square carton during actual falling or collision.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As mentioned in the background art of this application, through research, it is found that when the square cardboard box 33 falls or is impacted by an external force, it is not a certain area at a single hanging corner that is under pressure, but multiple areas at a hanging corner are simultaneously under pressure, or a certain area at two hanging corners is simultaneously under pressure. However, when the existing anti-compression test device for the hanging corners of the square cardboard box 33 is in use, it usually conducts an anti-compression test on a single area at the hanging corner of the square cardboard box 33, and cannot more realistically simulate the complex working environment of the square cardboard box 33 during actual falling or collision.

A notch 18 is formed on the bottom end surface of the concave table 2 below the rotary roller 8. By arranging the rotary feeding and discharging mechanism, not only can the square cardboard box 33 be effectively transferred, but also the stability of the square cardboard box 33 during the compressive test can be ensured. In addition, after the four hanging corners of the square cardboard box 33 are detected, it can be flipped 180 degrees, which is convenient for testing the other four hanging corners without manual interference and has a high degree of automation.

[0027] In this embodiment, the telescopic member specifically includes: a strip-shaped groove 14 formed on the inner side surface of the strip-shaped clamping plate 12, a lead screw 15 rotatably connected to the inside of the strip-shaped groove 14, and a stepping motor 16 embedded in one inner wall of the strip-shaped groove 14. An output shaft of the stepping motor 16 is fixedly connected to the lead screw 15. A moving plate 17 matching the strip-shaped groove 14 is movably connected to the inside of the strip-shaped groove 14. The lead screw 15 penetrates through the moving plate 17 and is threadedly connected thereto. A cross-shaped movable plate 13 is fixedly connected between the four moving plates 17. The arrangement of the telescopic member enables the top of the square cardboard box 33 to enter the inside of the first annular plate 20 to complete the compressive test.

[0028] In this embodiment, the multi-directional compressive test assembly specifically includes: a first annular plate 20 rotatably connected above the inside of the test chamber 7. A rotary drive mechanism is provided between the outer side surface of the first annular plate 20 and the inner wall of the test chamber 7. Above the inner wall of the first annular plate 20, a second annular plate 26 is fixedly connected. Above the conveyor belt 3, there is a square cardboard box 33. The hanging corners of the square cardboard box 33 include a first area 39, a second area 37, a third area 38, and an intersection point 40.

Through the multi-directional compressive test assembly provided in this application, compared with traditional compressive test devices, it has three different working modes. In the first working mode, an independent compressive test can be carried out on a certain area of a single hanging corner of the square cardboard box 33. In the second working mode, synchronous compressive tests can be carried out on multiple areas of a certain hanging corner of the square cardboard box 33. In the third working mode, synchronous compressive tests can be carried out on a certain area of two adjacent hanging corners on the same surface and at the same height of the square cardboard box 33. The three working modes can more realistically simulate the complex working environment of the square cardboard box 33 during actual dropping or collision, thereby reducing the error of the final test result and having high representativeness.

[0029] In this embodiment, the rotary drive mechanism specifically includes: an annular sliding groove 21 opened above the outer side surface of the first annular plate 20. At the position corresponding to the annular sliding groove 21 on the inner wall of the test chamber 7, a plurality of uniformly distributed support sliding plates 22 are fixedly connected, and the support sliding plates 22 are movably connected with the annular sliding groove 21. Above the support sliding plates 22, a rotary motor 23 is fixedly connected, and the output shaft of the rotary motor 23 is fixedly connected with a bevel gear 24. On the top surface of the first annular plate 20, a gear ring 25 meshing with the bevel gear 24 is fixedly connected. Through the multi-directional compressive test assembly provided in this application, the first annular plate 20 can be driven to rotate horizontally as needed, thereby automatically completing the transfer of the pressure measurement station and testing each hanging corner of the square cardboard box 33.

[0030] In this embodiment, four first cameras 31 are evenly embedded on the inner wall of the first annular plate 20, and a second camera 32 is embedded on the top wall of the test chamber 7 above the second annular plate 26. The first camera 31 and the second camera 32 are used to collect images after the compressive test of the square cardboard box 33. After sending the images to the background control terminal, the background control terminal analyzes and identifies the images, and then judges whether the compressive test of the square cardboard box 33 is qualified.

[0031] In this embodiment, the centering mechanism specifically includes: first push cylinders 4 symmetrically fixed to the top ends of the inner walls on both sides of the groove of the concave workbench 2, and a first push plate 5 is fixedly connected to the output shaft of the first push cylinder 4. The centering mechanism is used to push and center the square cardboard box 33.

[0032] In this embodiment, the sorting mechanism specifically includes: second push cylinders 34 fixedly connected to the top ends of the inner walls on both sides of the groove of the concave workbench 2 in an oblique diagonal manner, a second push plate 35 is fixedly connected to the output shaft of the second push cylinder 34, and an inclined guide plate 36 is fixedly connected to one side of the second push cylinder 34, and the top end of the inclined guide plate 36 penetrates into the groove of the concave workbench 2, and the guiding directions of the two inclined guide plates 36 are opposite. The sorting mechanism is used to separately export the qualified products and unqualified products after the test.

[0033] In this embodiment, support legs 1 are fixedly connected to both sides of the bottom end surface of the concave workbench 2 for supporting the concave workbench 2.

[0034] The working principle of the present invention is as follows: When in use, first, the square cardboard box 33 to be tested is placed on the left side of the conveyor belt 3. The conveyor belt 3 runs to drive the square cardboard box 33 to move forward. When the square cardboard box 33 reaches the centering mechanism, the two first push cylinders 4 of the centering mechanism run out their output shafts at the same time, so that the two first push plates 5 approach each other, and the two first push plates 5 push the square cardboard box 33 to the middle position of the concave workbench 2 and continue to move forward with the conveyor belt 3. Immediately afterwards, the square cardboard box 33 enters the test chamber 7 inside through the inlet and outlet 19 of the left test box 6. At this time, the rotary feeding and discharging mechanism and the multi-directional compressive test assembly in the test chamber 7 cooperate to perform a compressive test on four of the hanging corners of the square cardboard box 33.

[0035] The working process of the rotary feeding mechanism is as follows: after the square carton 33 is pushed to the center position, it can be moved by the conveyor belt 3 to just enter between the four strip pallets 12. After the square carton 33 is completely between the four strip pallets 12, the square carton 33 contacts the cross movable plate 13, and then the driving motor 9 is driven to drive the rotating roller 8 to rotate ninety degrees clockwise. During the process, the connecting rod 10 and the cross fixed plate 11 rotate accordingly, and the square carton 33 is restricted by the four strip pallets 12 and also rotates accordingly. At this time, the square carton 33 is transferred to the top of the rotating roller 8, and then the stepper motor 16 of the telescopic part drives the lead screw 15 to rotate, and the moving plate 17 slowly rises along the lead screw 15 in the strip groove 14. During the process, the cross movable plate 13 supporting the square carton 33 follows the rise, so that the top of the square carton 33 rises to the preset height inside the first annular plate 20 to prepare for the compression test of the multi-directional compression test assembly.

[0036] After the square carton 33 reaches the preset height, the two vertical test cylinders 29 are aligned and matched with the first areas 39 at the two hanging corners, the two oblique test cylinders 30 are aligned and matched with the intersection points 40 at the two hanging corners, the two transverse test cylinders 28 are aligned and matched with the second area 37 at one of the hanging corners and the third area 38 at the other hanging corner, and the two longitudinal test cylinders 27 are aligned and matched with the third area 38 at one of the hanging corners and the second area 37 at the other hanging corner. The multi-directional compression test assembly has three different working modes. In the first working mode, an independent compression test can be performed on a certain area at a single hanging corner of the square carton 33, specifically, a pressure test is performed on the corresponding area through any vertical test cylinder 29, or oblique test cylinder 30, or transverse test cylinder 28, or longitudinal test cylinder 27. In the second working mode, a synchronous compression test can be performed on multiple areas at a certain hanging corner of the square carton 33, specifically, a synchronous compression test is performed on multiple areas at the hanging corner through four test cylinders corresponding to the hanging corner. In the third working mode, a certain area at two adjacent hanging corners on the same surface and at the same height of the square carton 33 can be subjected to a synchronous compression test, that is, corresponding pressure is applied through the corresponding two test cylinders. The three working modes can more realistically simulate the complex working environment of the square carton 33 when it actually falls or collides, thereby reducing the error of the final test result and having a high degree of representativeness.

[0037] It should be noted that the four corners on the top of the square carton 33 are not all at the test station. Therefore, the present application drives the first annular plate 20 to rotate horizontally through the set rotation drive mechanism, and then automatically completes the transfer of the pressure measuring station, so as to test each corner of the square carton 33. The working process of the rotation drive mechanism is as follows: the rotation motor 23 drives the bevel gear 24 to rotate. Since the bevel gear 24 is meshed with the ring gear 25, as the bevel gear 24 rotates, the ring gear 25 and the first annular plate 20 follow the rotation. During the process, the support slide 22 and the annular slide groove 21 undergo relative displacement.

[0038] After the test is completed on the four hanging corners of the top of the square carton 33, the stepper motor 16 of the telescopic member drives the lead screw 15 to rotate in the opposite direction to return to the initial position. At this time, the square carton 33 completely falls between the four strip pallets 12. Then, the drive motor 9 drives the rotating roller 8 to rotate ninety degrees clockwise. The square carton 33 is placed flat on the conveyor belt 3 following the rotation. The conveyor belt 3 drives the square carton 33 to disengage from the rotary feeding mechanism in the left test chamber 7, and sends the square carton 33 to the rotary feeding mechanism in the right test chamber 7. The rotary feeding mechanism in the right test chamber 7 cooperates with the multi-directional compression test assembly to perform compression tests on the other four hanging corners of the square carton 33. In addition, in order to improve the efficiency of the square carton 33 disengaging from the rotary feeding mechanism, during the process, the square carton 33 can be pushed to quickly disengage from the strip pallet 12 by driving the cross movable plate 13 to move outward.

[0039] During the test of the square carton 33, the first camera 31 and the second camera 32 collect images of the square carton 33 after the compression test, and after sending the images to the background control terminal, the background control terminal analyzes and identifies the images, and then determines whether the compression test of the square carton 33 is qualified. After the square carton 33 completes the test at all the hanging corners and is sent out of the test box 6 on the right, the qualified products that have completed the test are separated from the unqualified products through the material separation mechanism. Specifically, if the compression test of the square carton 33 is qualified, when the square carton 33 passes the first second push cylinder 34, the second push cylinder 34 runs to extend the output shaft to drive the second push plate 35 to push the square carton 33 into the first oblique guide plate 36, and the first oblique guide plate 36 sends the qualified square carton 33 out. If the compression test of the square carton 33 fails, when the square carton 33 passes through the second second pushing cylinder 34, the second pushing cylinder 34 will run to extend the output shaft to drive the corresponding second pushing plate 35 to push the square carton 33 into the second inclined guide plate 36, and the second inclined guide plate 36 will send the unqualified square carton 33 out.

[0040] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.

[0041] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
