Description

Technical Field

[0001] The utility model relates to the technical field of carton performance detection, in particular to a carton compression resistance detection device. Background Art

[0002] Cardboard boxes are the most widely used packaging products. Depending on the material used, they come in various sizes and models, including corrugated boxes and single-layer cardboard boxes. As an indispensable component of modern logistics, cartons are responsible for containing, protecting products, and maintaining their aesthetic appeal. Their most important function lies in their protective qualities, and compressive strength, a comprehensive reflection of these protective properties, is their most fundamental performance characteristic. Compressive strength refers to the maximum pressure a carton can withstand when placed in a three-dimensional position. Testing carton compressive strength is crucial to preventing deformation and damage to products during handling, stacking, storage, and transportation due to insufficient strength.

[0003] An existing Chinese patent (publication number CN219657324U) discloses a high-pressure-resistance device for carton production. Telescopic plates are movably installed on both sides of a connecting plate, and a second pressure sensor is installed at the bottom of the telescopic plate through a second mounting shell. If the volume of the produced carton is large, the telescopic plate can be extended or retracted outward, and the pressure of the produced carton can be detected by the second pressure sensor, so that the high-pressure-resistance device for carton production can perform pressure detection on cartons of different sizes.

[0004] However, the strong pressure resistance device for carton production designed above still has some shortcomings in actual use: when using this strong pressure resistance device for carton production, each time a carton is subjected to pressure resistance testing, manual adjustment is required to calibrate the position of the carton to be tested and the testing device, which increases the preparation time before testing each carton. When a large number of cartons need to be tested, the accumulated preparation time of the cartons is long, which has a certain impact on the rhythm of the entire testing process, limiting the number of cartons that can be tested per unit time, and affecting the overall efficiency of the carton pressure resistance testing.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5The utility model provides a technical solution: it includes a detection platform 1 and a detection component connected to the top of the inner wall of the detection platform 1, one side of the detection platform 1 is fixedly connected to a mounting block 21, and the number of mounting blocks 21 is set in multiples. A transmission component is provided on the mounting block 21, one end of the mounting block 21 is fixedly connected to a second connecting plate 19, and a second mounting plate 10 is fixedly installed on the top of the second connecting plate 19. A positioning component is provided on the second mounting plate 10, and the positioning component includes an asynchronous motor 18, which is fixedly mounted on one side of the second mounting plate 10, and the driving end of the asynchronous motor 18 is fixedly connected to a driving gear 15. A rack 14 is slidably connected to one side of the second mounting plate 10, and the number of racks 14 is set in two. The opposite sides of the two racks 14 are meshed with the driving gear 15, and the top side of the rack 14 is fixedly connected to the first connecting plate 9, and one side of the first connecting plate 9 is fixedly connected to the first push plate 13.

[0023] It should be noted that the two racks 14 are respectively slidably arranged above and below one side of the second mounting plate 10. When the driving gear 15 rotates clockwise, the racks 14 on both sides are driven to move relative to each other, so that the first push plates 13 are brought close to each other to center the carton.

[0024] During specific implementation, when the carton moves to the detection platform 1 via the conveyor belt 7 in the direction to be detected, the asynchronous motor 18 is started, and the driving end of the asynchronous motor 18 drives the driving gear 15 to rotate clockwise or counterclockwise. When the driving gear 15 rotates, it drives the two racks 14 to move toward or away from each other. The rack 14 slides horizontally on the second mounting plate 10 through the slide groove on the second mounting plate 10. When the rack 14 moves, it will drive the first connecting plate 9 to move, and the first connecting plate 9 drives the first push plate 13 to move. The two first push plates 13 calibrate the moving carton to be detected so that it can be better moved to the detection platform 1.

[0025] See Figure 3 One side of the first connecting plate 9 is rotatably connected to a gear ring 12 , a threaded hole is provided on the gear ring 12 , a threaded rod 11 is threadedly connected to the threaded hole, and the first push plate 13 is fixedly connected to one end of the threaded rod 11 near the driving gear 15 .

[0026] By setting the threaded rods 11 , when the cartons have different sizes, the staff can also move the pawl 20 and rotate the gear ring 12 to rotate the threaded rods 11 and change the relative distance between the two threaded rods 11 .

[0027] See Figure 4 A damping spring 16 is fixedly connected to one side of the first push plate 13 away from the first connecting plate 9 , and the other end of the damping spring 16 is fixedly connected to the second push plate 17 .

[0028] By providing the shock-absorbing spring 16 , the shock-absorbing spring 16 on one side of the first push plate 13 and the second push plate 17 can play a buffering role when positioning the carton, thereby avoiding excessive squeezing of the carton.

[0029] See Figure 4 A sliding groove is provided on the second mounting plate 10, and a slider is connected to the side of the rack 14 close to the second mounting plate 10, and the slider is slidably connected to the second mounting plate 10 through the sliding groove.

[0030] By providing the sliding groove, the two racks 14 can slide on one side of the second mounting plate 10 , and drive the first connecting plate 9 to move when sliding.

[0031] See Figure 3 A pawl 20 is clamped on one side of the gear ring 12, a rectangular block is fixedly installed on the first connecting plate 9, a return spring is fixedly connected to the top of the rectangular block, and one end of the return spring is fixedly connected to the pawl 20.

[0032] By providing the pawl 20 , the threaded rod 11 can be moved to a suitable position to adapt to cartons of different sizes and calibrate any possible deviation of the cartons.

[0033] See Figure 1 The transmission component includes a drive motor 8 connected to one side of the mounting block 21. The driving end of the drive motor 8 is fixedly connected to a rotating shaft, and a conveyor belt 7 is movably connected to the rotating shaft. There are two conveyor belts 7, and the two conveyor belts 7 are perpendicular to each other.

[0034] It should be noted that the conveyor belt 7 opposite to the third push plate 6 is used to unload the cartons after inspection, and the conveyor belt 7 perpendicular to the third push plate 6 is used to load the cartons to be inspected, and a positioning component is provided on the conveyor belt 7 perpendicular to the third push plate 6.

[0035] By setting up the conveyor belt 7, when the carton needs to be conveyed to the testing platform 1 for pressure resistance testing, the carton is placed on the conveyor belt 7 perpendicular to the third push plate 6, and the drive motor 8 is started. The driving end of the drive motor 8 drives the rotating shaft to rotate. Since the conveyor belt 7 is movably connected to the rotating shaft, the carton can be conveyed from the direction to be tested to the appropriate position on the testing platform 1 under the rotation of the conveyor belt 7, which facilitates the conveyor belt 7 to transfer the loading and unloading processes of the carton, thereby improving the unloading speed after the carton testing is completed and improving the testing efficiency.

[0036] See Figure 1 and Figure 2 A first mounting plate 4 is fixedly mounted on one side of the detection platform 1 , a cylinder 5 is fixedly mounted on the bottom of one side of the first mounting plate 4 , and a third push plate 6 is fixedly connected to the driving end of the cylinder 5 .

[0037] After the detection is completed, the third push plate 6 is started by the cylinder 5 to push the carton along the moving direction of the third push plate 6, so that the carton contacts the conveyor belt 7 opposite to the third push plate 6 and is conveyed to the detection completion area via the conveyor belt 7.

[0038] See Figure 1 An electric push rod 3 is fixedly installed on the top of the inner wall of the testing platform 1, and the driving end of the electric push rod 3 is fixedly connected to the lower pressing plate 2.

[0039] It should be noted that a pressure sensor is installed inside the lower pressure plate 2 for performing pressure resistance testing on the carton when the lower pressure plate 2 moves downward. A control panel is fixedly installed on one side of the outer frame of the testing platform 1, and the control panel is electrically connected to the lower pressure plate 2.

[0040] By setting up the lower pressure plate 2, when the carton moves to the bottom of the lower pressure plate 2, the electric push rod 3 is started through the control panel to drive the lower pressure plate 2 to move closer to the carton, and the pressure resistance of the carton is tested by the pressure sensor installed inside the lower pressure plate 2.

[0041] Working principle: When the carton moves to the detection platform 1 via the conveyor belt 7 in the direction to be detected, the asynchronous motor 18 is started, and the driving end of the asynchronous motor 18 drives the driving gear 15 to rotate. When the driving gear 15 rotates, it drives the two racks 14 to move toward or away from each other. The rack 14 slides horizontally on the second mounting plate 10 through the slide groove on the second mounting plate 10. When the rack 14 moves, it will drive the first connecting plate 9 to move, and the first connecting plate 9 drives the first push plate 13 to move. The two first push plates 13 calibrate the moving carton to be detected so that it can be better moved to the detection platform 1.

[0042] When the cartons are of different sizes, the staff can also move the pawl 20, rotate the gear ring 12, and rotate the threaded rod 11 to change the relative distance between the two threaded rods 11. The shock-absorbing spring 16 and the second push plate 17 on one side of the first push plate 13 can act as a buffer when positioning the carton to avoid excessive squeezing of the carton.

[0043] When the carton needs to be transported to the testing platform 1 for compression resistance testing, the carton is placed on the conveyor belt 7 perpendicular to the third push plate 6, and the drive motor 8 is started. The driving end of the drive motor 8 drives the rotating shaft to rotate. Since the conveyor belt 7 is movably connected to the rotating shaft, the carton can be transported from the direction to be tested to the appropriate position on the testing platform 1 under the rotation of the conveyor belt 7. After the test is completed, the third push plate 6 is started by the cylinder 5, and the carton is pushed along the moving direction of the third push plate 6, so that the carton contacts the conveyor belt 7 opposite to the third push plate 6, and is transported to the test completion area via the conveyor belt 7.
