Description

Technical Field

[0001] The present invention relates to the technical field of carton compression resistance detection, and in particular to a carton compression resistance detection device. Background Art

[0002] Cartons are the most widely used packaging products, usually made of paper. They are used to package various items and provide protection for them during transportation, storage and sales. The raw material for making cartons is mainly paper, which has a wide source and is relatively low in price, which can effectively reduce packaging costs.

[0003] After searching, the Chinese patent with publication number CN119178678A discloses a compression test device for the production of corrugated paper packaging boxes and its use method, including a base, a frame fixedly connected to the top of the base, an internal transmission connection of the frame with a pressure plate, a carton located at the bottom of the pressure plate provided on the top of the base, connecting blocks provided on both sides of the top of the pressure plate, the interior of the connecting block is movably connected to an axle through a bearing, the surface of the axle is fixedly connected to a support plate, the side of the support plate away from the axle extends to the outside of the carton and contacts the surface of the carton, the surface of the frame is provided with a transmission structure, and the transmission structure can control the automatic swing of the support plate. By setting a fixed connection between the frame, pressure plate, base and other components, the stability and accuracy of the detection process are ensured, and the relative position of the pressure plate and the carton is set so that the compression test can act directly on the carton, effectively evaluating the compression performance of the carton. However, when this solution is actually used, there are still the following deficiencies:

[0004] The above-mentioned carton compression test device can only perform static compression tests on cartons. However, in actual usage scenarios, cartons often face more complex and harsh conditions. On the one hand, during the transportation process, they may be subjected to violent handling by workers, such as being thrown or thrown at will, causing the cartons to instantly bear huge impact forces; on the other hand, during transportation, the bumps and vibrations caused by the vehicle's driving and the impact caused by uneven roads will put the cartons in a dynamic stress environment. These dynamic external forces are completely different from the stable forces during static compression tests. The existing testing devices cannot simulate such dynamic stress conditions, and it is difficult to accurately evaluate the compression performance of cartons in actual use, which makes the test results deviate greatly from the actual usage conditions.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1-3 A carton compression resistance detection device includes a bottom plate 11, two support frames 12 are symmetrically fixedly installed on the top surface of the bottom plate 11, and guide openings 13 are opened on the opposite sides of the two support frames 12. A driving mechanism is provided on the inner sides of the two support frames 12, and a support plate 31 is provided between the two support frames 12. Two elastic connecting arms 32 are symmetrically fixedly installed on both sides of the support plate 31, and a test pressure plate 33 is fixedly installed at the bottom end of the four elastic connecting arms 32. A pressure sensor 34 is provided on the bottom surface of the support plate 31.

[0035] The driving mechanism includes a servo motor 21 fixedly mounted on the top surface of a support frame 12, a driving screw 22 fixedly mounted on the output end of the servo motor 21, and a guide block 23 slidably mounted on the inner wall of the other support frame 12, and the end of the guide block 23 passes through the guide opening 13 and is fixedly connected to the end of the support plate 31.

[0036] During the static compression test, the staff can place the carton to be tested on the top surface of the bottom plate 11 and lay it flat, and then start the servo motor 21 to drive the driving screw 22. When the driving screw 22 rotates, one end of the support plate 31 is screwed to the driving screw 22, and the other end is slidably connected to the inner wall of the support frame 12 through the guide block 23. Therefore, when the driving screw 22 rotates, the support plate 31 can be driven to move downward along the guide port 13, and continuous pressure can be applied to the carton to be tested through the elastic connecting arm 32 and the test pressure plate 33, and the test force can be collected through the pressure sensor 34 to understand the test data. After the test is completed, the servo motor 21 can be reversed to reset the test pressure plate 33 and the tested carton can be removed.

[0037] Reference Figure 3 、 Figure 4 、 Figure 5A connecting frame 41 is slidably installed on the inner wall of one of the support frames 12, and the connecting frame 41 is set to be U-shaped. The end of the connecting frame 41 passes through the guide port 13 and is fixedly connected to the side of the support plate 31. Two clamps 42 are slidably installed on the inner wall of the connecting frame 41. The opposite sides of the two clamps 42 are screwed to the drive screw 22. A control component connected to the connecting frame 41 is provided between the two clamps 42. The control component includes a transmission gear 43 rotatably installed on the inner wall of the connecting frame 41, and the opposite sides of the two clamps 42 are fixedly installed with fixed racks 44 that mesh with the transmission gear 43. Two support springs 45 are symmetrically fixedly installed between the opposite sides of the two clamps 42. A limiting structure corresponding to one of the two clamps 42 is provided on the support frame 12.

[0038] The limiting structure includes an electric push rod 46 fixedly installed on the side of the support frame 12. The telescopic end of the electric push rod 46 passes through the side of the support frame 12 and is fixedly installed with a limiting strip 47. The side of the splint 42 is provided with a limiting pressure groove 48 corresponding to the limiting strip 47, and the limiting strip 47 is slidably connected to the limiting pressure groove 48.

[0039] When conducting a dynamic compression test, the staff can first turn on the servo motor 21 to move the support plate 31 to the corresponding height for the test, and then place the carton to be tested on the bottom plate 11. In the initial state, the electric push rod 46 is in an extended state and drives the limit bar 47 to push the clamping plate 42. At this time, the two clamping plates 42 can clamp the driving screw 22 and the opposite sides of the two clamping plates 42 can form threaded holes and be screwed to the driving screw 22, ensuring that the support plate 31 can be driven when the driving screw 22 rotates. During the test, the staff can shorten the electric push rod 46 and drive the limit bar 47 to separate from the limit pressure groove 48. At this time, the two clamping plates 42 are supported by the spring 45 between them. The plates 42 can slide in the direction away from each other, and when sliding, the transmission gear 43 can be driven to rotate by the fixed rack 44, ensuring that the two splints 42 can slide synchronously along the connecting frame 41 through the slide groove and the slider to separate from the drive screw 22. When the splint 42 is separated from the drive screw 22, the support plate 31 can slide downward freely under the action of gravity, and the impact pressure of the test carton can be tested through the test pressure plate 33, and data can be collected through the pressure sensor 34. By adjusting the support plate 31 to different heights and matching the different weights of the counterweight plate 52, multiple sets of data can be tested on the test carton, which improves the averageness of the test and ensures that the test results are more accurate.

[0040] Reference Figure 3 Four fixing rods 51 are symmetrically fixed on the top surface of the support plate 31. The outer walls of two fixing rods 51 on the same side of the four fixing rods 51 are covered with counterweight plates 52, and the top ends of the fixing rods 51 are provided with locking nuts 53 corresponding to the counterweight plates 52.

[0041] The locking nut 53 can be removed from the fixing rod 51 to install the weight on the support plate 31. According to the specific test situation, the counterweight plate 52 can be selected and mounted on the fixing rod 51. After completion, it can be fixed with the locking nut 53.

[0042] Reference Figure 6 、 Figure 7 A fixing frame 63 is fixedly installed on the side of the support frame 12, and a winding disk 64 is rotatably installed on the side of the fixing frame 63. A pull rope 65 is provided on the inner side of the winding disk 64, and the pulling end of the pull rope 65 is fixedly connected to the top surface of the support plate 31. A test component corresponding to the winding disk 64 is provided on the side of the support frame 12. The test component includes a bracket 61 fixedly installed on the top surface of the support frame 12, and guide wheels 62 are rotatably installed at both ends of the bracket 61, and the pull rope 65 passes through the two guide wheels 62 in sequence. A driven bevel gear 66 is fixedly installed on the end of the winding disk 64, and a driving bevel gear 67 meshing with the driven bevel gear 66 is rotatably installed on the side of the support frame 12, and the driving bevel gear 67 is connected to the driving screw 22 through a driven wheel and a synchronous belt transmission. A toggle structure corresponding to the pull rope 65 is provided on the side of the support frame 12.

[0043] During normal static compression test, the driving screw 22 rotates to drive the support plate 31 to move, which can drive the driving bevel gear 67 to rotate through the driven wheel and the synchronous belt. The driving bevel gear 67 is engaged with the driven bevel gear 66, and then the driven bevel gear 66 and the winding disk 64 are driven to rotate. When the support plate 31 moves upward, the winding disk 64 rotates to reel in the pull rope 65, and when the support plate 31 moves downward, the winding disk 64 can be reversed to unwind the pull rope 65, ensuring that the pull rope 65 can be tightened between the test pressure plate 33 and the winding disk 64.

[0044] Reference Figure 6 、 Figure 8 The toggle structure includes a driving motor 71 fixedly mounted on the side of the support frame 12, a driving roller 72 is fixedly mounted on the output end of the driving motor 71, a cam frame 73 is rotatably mounted on the side of the support frame 12 through a mounting frame, positioning plates are provided on both sides of the cam frame 73, and an adjusting roller 74 corresponding to the driving roller 72 is fixedly mounted on the side of the cam frame 73, and an adjusting mechanism is provided between the driving roller 72 and the adjusting roller 74.

[0045] The adjustment mechanism includes a guide rod 75 fixedly mounted on the side of the drive motor 71, and an adjustment screw 76 located on the side of the guide rod 75 is rotatably mounted on the side of the drive motor 71. A slide 77 is mounted on the guide rod 75 and the adjusting screw 76. A transmission ring 78 is rotatably mounted on the outer wall of the slide 77. The outer wall of the transmission ring 78 is in contact with the outer walls of the drive roller 72 and the adjustment roller 74.

[0046] When the test pressure plate 33 is moved to the state of applying pressure to the carton to be tested, the staff can turn on the drive motor 71 to drive the drive roller 72 to rotate. When the drive roller 72 rotates, it can drive the transmission ring 78, and drive the adjusting roller 74 through the transmission ring 78, thereby driving the cam frame 73 to rotate. When the cam frame 73 rotates, the pull rope 65 can be dialed. Since the reel 64 and the drive screw 22 are connected by the driven bevel gear 66 and the driving bevel gear 67, the reel 64 cannot rotate when the drive screw 22 is stationary. At this time, the pull rope 65 is dialed to pull the test pressure plate 33 and the test pressure plate 33 can be reset under the action of the elastic connecting arm 32, thereby During the rotation of the frame 73, the test pressure plate 33 can be vibrated, thereby simulating the pressure resistance test of cartons on bumpy roads; and before conducting the simulated carton bumpy road pressure resistance test, the staff can adjust the rotation speed of the cam frame 73 according to the test conditions. The adjusting screw 76 can be rotated during adjustment. Since the slide plate 77 is screwed to the adjusting screw 76 and is slidably connected to the guide rod 75, the slide plate 77 can be driven when the adjusting screw 76 rotates, thereby realizing the adjustment of the position of the transmission ring 78. The driving roller 72 and the adjusting roller 74 are both frustum-shaped and are arranged relative to each other. Therefore, when adjusting the position of the transmission ring 78, the rotation speed of the cam frame 73 can be adjusted, which can simulate more scenarios and ensure more accurate detection.

[0047] The specific working principle of the present invention is as follows:

[0048] When in use, the device can provide two compression test modes for the carton to be tested, one is a static compression test and the other is a dynamic compression test. Specifically, during the static compression test, the staff can place the carton to be tested on the top surface of the bottom plate 11 and lay it flat, and then start the servo motor 21 to drive the driving screw 22. When the driving screw 22 rotates, one end of the support plate 31 is screwed to the driving screw 22, and the other end is slidably connected to the inner wall of the support frame 12 through the guide block 23. Therefore, when the driving screw 22 rotates, the support plate 31 can be driven to move downward along the guide port 13, and continuous pressure can be applied to the carton to be tested through the elastic connecting arm 32 and the test pressure plate 33, and the test force is collected by the pressure sensor 34 to understand the test data. After the test is completed, the servo motor 21 can be reversed to reset the test pressure plate 33 and the tested carton can be removed.

[0049] When conducting a dynamic compression test, the staff can first turn on the servo motor 21 to move the support plate 31 to the corresponding height of the test, and then remove the fixing rod 51 by the locking nut 53, and then install the weight on the support plate 31. According to the specific test situation, the counterweight plate 52 can be selected and mounted on the fixing rod 51. After completion, it can be fixed by the locking nut 53. After the counterweight plate 52 is installed, the carton to be tested can be placed on the bottom plate 11. In the initial state, the electric push rod 46 is in an extended state and drives the limit bar 47 to push the splint 42. At this time, the two splints 42 can clamp the drive screw 22 and the opposite sides of the two splints 42 can form a threaded hole and be screwed to the drive screw 22, ensuring that the drive screw 22 can drive the support plate 31 when it rotates. During the test, the staff can turn the electric push rod 46 The two clamping plates 42 can slide in the direction away from each other under the action of the supporting spring 45 between the two clamping plates 42, and the transmission gear 43 can be driven to rotate by the fixed rack 44 during sliding, ensuring that the two clamping plates 42 can slide synchronously along the connecting frame 41 and separate from the driving screw 22 through the sliding groove and the slider. When the clamping plates 42 are separated from the driving screw 22, the support plate 31 can slide downward freely under the action of gravity, and the impact pressure of the test carton is tested through the test pressure plate 33, and data is collected through the pressure sensor 34. By adjusting the support plate 31 to different heights and matching the different weights of the counterweight plate 52, multiple sets of data tests can be performed on the test carton, thereby improving the average of the test and ensuring that the test results are more accurate.

[0050] When the static compression test is carried out normally, the driving screw 22 rotates to drive the support plate 31 to move, which can drive the driving bevel gear 67 to rotate through the driven wheel and the synchronous belt. The driving bevel gear 67 is engaged with the driven bevel gear 66, and then the driven bevel gear 66 and the winding disk 64 can be driven to rotate. When the support plate 31 moves upward, the winding disk 64 rotates to reel the pull rope 65, and when the support plate 31 moves downward, the winding disk 64 can be reversed to unwind the pull rope 65, ensuring that the pull rope 65 can be tightened between the test pressure plate 33 and the winding disk 64; when the test pressure plate 33 is moved to the state of applying pressure to the carton to be tested, the staff can turn on the drive motor 71 to drive the drive roller 72 to rotate When the driving roller 72 rotates, it can drive the transmission ring 78, and drive the adjusting roller 74 through the transmission ring 78, thereby driving the cam frame 73 to rotate. When the cam frame 73 rotates, the pull rope 65 can be dialed. Since the winding disc 64 and the driving screw 22 are connected by the driven bevel gear 66 and the driving bevel gear 67, the winding disc 64 cannot rotate when the driving screw 22 is stationary. At this time, the pull rope 65 is dialed to pull the test pressure plate 33, and the test pressure plate 33 can be reset under the action of the elastic connecting arm 32. In this way, the test pressure plate 33 can be vibrated during the rotation of the cam frame 73, thereby simulating the compression test of the carton on a bumpy road.

[0051] Before conducting the simulated cardboard bumpy road pressure test, the staff can adjust the rotation speed of the cam frame 73 according to the test conditions. The adjusting screw 76 can be rotated during adjustment. Since the slide plate 77 is screwed to the adjusting screw 76 and is slidably connected to the guide rod 75, the slide plate 77 can be driven when the adjusting screw 76 rotates, thereby adjusting the position of the transmission ring 78. The driving roller 72 and the adjusting roller 74 are both frustum-shaped and relatively arranged. Therefore, when adjusting the position of the transmission ring 78, the rotation speed of the cam frame 73 can be adjusted, which can simulate more scenarios and ensure more accurate detection.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
