Description

Technical Field

[0001] This utility model relates to the field of box testing technology, specifically a gravity testing experimental device used in box production. Background Technology

[0002] In the production of boxes, precise testing of the box's load-bearing capacity is a crucial step in ensuring product quality. Whether it's packaging boxes used for logistics and transportation, protective boxes for equipment in the industrial field, or storage boxes for daily life, their load-bearing performance directly affects their safety and reliability. Therefore, during the production process of all types of boxes, it is necessary to use specialized weighing and force testing equipment to test their load-bearing limits, compressive deformation, and other indicators.

[0003] In actual testing, the current weighing test equipment suffers from various manufacturing specifications of the chamber, with significant differences in length, width, and height. The chamber is prone to horizontal displacement or even tilting due to a lack of effective constraints. This displacement not only leads to distortion of the collected pressure data and affects the accuracy of the test results, but may also cause safety hazards due to the chamber tipping over. At the same time, it reduces testing efficiency, requiring operators to repeatedly adjust the position of the chamber to ensure consistency of test conditions. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-6 As shown, this utility model is a gravity testing experimental device for box manufacturing, comprising:

[0032] Test socket 11;

[0033] The test component includes a support frame 21, a telescopic rod 22, a hydraulic cylinder 23, and a pressure plate 24. The support frame 21 is welded to the top of the test base 11. The hydraulic cylinder 23 is disposed on the top of the inner surface of the support frame 21. The top of the telescopic rod 22 extends to the drive end of the hydraulic cylinder 23. The pressure plate 24 is fixed to the bottom of the telescopic rod 22.

[0034] Hydraulic cylinder 23 starts operating, which drives the telescopic rod 22 to extend, and the bottom pressure plate 24 connected to the telescopic rod 22 moves downward in sync. The pressure plate 24 gradually presses down to the top of the box and applies pressure to the box, simulating the weight that the box may bear in actual use.

[0035] The positioning component includes a threaded rod 33, a nut ring 34, a positioning plate 35, a hole 36, and an inner groove 39. The inner groove 39 is opened inside the pressure plate 24. The threaded rod 33 is located in the middle of the inner surface of the inner groove 39. The hole 36 is opened on the upper part of the positioning plate 35 and is slidably connected to the outer surface of the threaded rod 33. The nut ring 34 is threadedly connected to the outer surface of the threaded rod 33 and one end is tightly fitted to the upper part of one end of the positioning plate 35.

[0036] Multiple positioning plates 35 are distributed at the bottom of the pressure plate 24. They can slide outside the threaded rod 33 through the holes 36 to achieve flexible position adjustment. After the positioning plates 35 are adjusted to fit the circumference of the box, they are tightened by the rotation of the nut ring 34 on the threaded rod 33. This can stably lock the position of the positioning plates 35, thereby forming a reliable circumferential constraint on the box. This can effectively prevent the box from horizontal displacement or tilting due to uneven force during the pressure test, ensuring that the box is always in the preset test position. There is no need for the operator to repeatedly adjust the position of the box, thus ensuring the consistency of the test conditions.

[0037] Guide rods 32 are provided at both ends of the inner surface of the inner groove 39, and guide holes 37 are provided at both ends of the positioning plate 35. The guide holes 37 are slidably connected to the outside of the guide rods 32.

[0038] The operator slides the positioning plate 35 outside the threaded rod 33 through the hole body 36, while the guide hole 37 slides synchronously outside the guide rod 32, thereby adjusting the position of the positioning plate 35.

[0039] A load-bearing plate 25 is provided on the top of the test base 11, and a weighing sensor 26 is provided between the test base 11 and the load-bearing plate 25.

[0040] During the pressure application process, the weighing sensors 26, which are evenly distributed at the bottom of the load-bearing platform, will detect the pressure borne by the load-bearing platform in real time, thereby accurately reflecting the pressure borne by the box and obtaining relevant data on the weight and load-bearing performance of the box.

[0041] A display screen 27 is fixedly connected to one end of the outer surface of the test stand 11, and a data acquisition device 28 is provided on the upper part of the display screen 27;

[0042] The data acquisition unit 28, electrically connected to the load cell 26 and the hydraulic cylinder 23 respectively, begins operation, acquiring pressure data detected by the load cell 26 and pressure parameters of the hydraulic cylinder 23 in real time. This acquired data is transmitted to the display screen 27, which is electrically connected to the data acquisition unit 28. The display screen 27 displays the data in an intuitive manner, facilitating real-time observation and recording of various data during the test by the operator, ensuring the smooth progress of the test and the accurate acquisition of test results.

[0043] Slide plates 31 are fixedly connected to both sides of the outer surface of the pressure plate 24. Slide grooves 38 are provided on both sides of the support frame 21, and the slide plates 31 are slidably connected inside the slide grooves 38.

[0044] When the pressure plate 24 moves up and down, the slide plate 31 slides inside the slide groove 38 at the same time, which supports the pressure plate 24.

[0045] Working principle:

[0046] First, the box to be tested is placed on top of the load-bearing platform. At this time, the multiple positioning plates 35 distributed at the bottom of the pressure plate 24 are in the initial state. Then, the operator slides the positioning plates 35 outside the threaded rod 33 through the hole 36, while the guide hole 37 slides synchronously outside the guide rod 32, so that the multiple positioning plates 35 gradually fit into the four sides of the box. By rotating the nut ring 34 on the threaded rod 33, the nut ring 34 is fastened to the outer end of the positioning plate 35, thereby fixing the position of the positioning plate 35 after it has moved.

[0047] This step allows for precise adjustment of enclosures of different lengths and widths. Regardless of the size of the enclosure, the positioning plate at position 35 can be adjusted to fit around the enclosure. This breaks the limitations of traditional fixed structures on enclosure size, greatly improving the versatility of the device while providing reliable circumferential constraints on the enclosure. This ensures that the enclosure is always in the preset test position, providing strong support for the stability of the testing process.

[0048] Please see Figure 1-6 As shown, this embodiment, based on the above embodiment, further includes:

[0049] The locking component includes a rubber clamping ring 41, a rubber clamping ring 42, and a support rod 43. The support rod 43 is fixed between the rubber clamping ring 41 and the rubber clamping ring 42. The rubber clamping ring 42 is clamped and connected to the outer surface of the guide rod 32, and the rubber clamping ring 41 is clamped and connected to the outer surface of the threaded rod 33.

[0050] By utilizing the elastic clamping force of rubber clamping ring 41 and rubber clamping ring 42, the nut ring 34 is effectively prevented from rotating and loosening due to vibration and other factors during the test, and the positioning plate 35 is prevented from accidentally sliding along the guide rod 32.

[0051] A handle 44 is fixedly connected to the top of the rubber clamp 41, and rubber posts 45 are glued to the bottom of both the rubber clamp 41 and the rubber clamp 42.

[0052] After the rubber clamp 41 and the rubber clamp 42 are securely clamped to the outside of the threaded rod 33 and the guide rod 32 respectively, the rubber posts 45 at their bottoms will abut against the bottom of the threaded rod 33 and the guide rod 32 respectively.

[0053] Working principle:

[0054] After the positioning plate 35 is moved to the position and fixed by the nut ring 34, the rubber clamping ring 41 is clamped on the outside of the threaded rod 33 and blocked at the outer end of the nut ring 34; at the same time, the rubber clamping ring 42 is clamped on the outside of the guide rod 32 and blocked at the outer end of the positioning plate 35, and the rubber post 45 at its bottom will abut against the bottom of the threaded rod 33 and the guide rod 32 respectively.

[0055] This step effectively prevents the nut ring 34 from rotating and loosening due to vibration or other factors during the test, and also prevents the positioning plate 35 from accidentally sliding along the guide rod 32.
