Description

Technical Field

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

[0002] As a common packaging material, cartons are widely used in logistics, warehousing, transportation and other fields. Their load-bearing capacity is one of the important indicators to measure the quality of cartons, which is directly related to the safety of packaged items and transportation efficiency. Through testing, the maximum load-bearing limit of the carton can be determined to avoid carton breakage or damage due to overweight during transportation, thereby protecting the safety of internal items.

[0003] In traditional dynamic load-bearing tests of cartons, shaking equipment is used to simulate the shaking state of cartons during transportation, so as to test the load-bearing capacity of cartons during transportation.

[0010] Furthermore, a ball groove is provided on the top of the bottom plate corresponding to the ball, and the inner peripheral side of the ball groove is an inclined surface inclined upward, which is used to limit the movement range of the bottom plate.

[0029] A ball groove 46 is provided at the top of the bottom plate 41 corresponding to the ball 34, and the inner peripheral side of the ball groove 46 is an inclined surface inclined upward, which is used to limit the movement range of the bottom plate 41, prevent the bottom plate 41 from driving the through hole 44 on the top of the cover plate 43 to hit the outside of the connecting rod 33 during the shaking process to generate noise, and prevent damage to the connecting rod 33.

[0031] It also includes a positioning component 5 for positioning the carton 100 to be tested; the positioning component 5 includes two groups of sliders 51, the two sliders 51 in one group are located at the front and rear sides of the carton 100 to be tested, and the two sliders 51 in the other group are located at the left and right sides of the carton 100 to be tested, and the sliders 51 are all slidably set on the inner side of the slide groove 47 at the bottom of the bottom plate 41, and the bottom of the sliders 51 are provided with clamping blocks 55 for positioning the carton 100 to be tested; wherein, the two sliders 51 in each group are driven to slide by external force; specifically, the outer sides of the two sliders 51 in each group are fixedly provided with tooth plates 57, and the two tooth plates 57 in each group are meshingly arranged on the outer side of the same gear 58, and the two gears 58 are rotatably installed between the bottom plate 41 and the cover plate 43, and the motor B59 for driving the two gears 58 is fixedly provided at the bottom of the bottom plate 41 and the top of the cover plate 43.

[0032] A slide plate 52 is slidably arranged on the inner side of the slider 51, a limit block 53 is fixedly arranged on the top of the slide plate 52 to prevent the slide plate 52 from separating from the bottom plate 41, a clamping block 55 is fixedly arranged on the bottom of the slide plate 52, and a limit plate 54 is fixedly arranged between the slide plate 52 and the clamping block 55; wherein, the slide plate 52 falls freely by its own gravity, so as to control the bottom plate 41 to move downward to drive the limit plate 54 to fall on the top of the carton 100 to be tested, and prevent the carton 100 to be tested from being oppressed.

[0033] The bottom of the slider 51 is not lower than the bottom of the bottom plate 41, and a receiving groove 56 for accommodating the limit plate 54 is opened at the bottom of the slider 51, so that when the bottom plate 41 approaches the top of the carton 100 to be tested, the limit plate 54 is pushed to be located on the inner side of the receiving groove 56, so that the bottom of the bottom plate 41 and the top of the carton 100 to be tested are in contact with each other to ensure the uniformity of pressure.

[0034] Principle and advantages of carton load-bearing detection device: First, place the carton 100 to be tested on the top of the test plate 11 inside the test box 1, and then drive the pressure plate 36 to move downward through the hydraulic push rod 37 on the top of the test box 1, so that the pressure plate 36 presses down the connecting rod 33 at the bottom of the connecting frame 32 through the pressure rod 31, and the connecting rod 33 drives the pressure component 4 to approach the top of the carton 100 to be tested. As the hydraulic push rod 37 continues to apply pressure to the pressure component 4, the weighing sensor 12 at the bottom of the test plate 11 can detect the change in the pressure on the carton 100 to be tested. At this time, the static load-bearing capacity of the carton 100 to be tested can be detected by recording the detection value of the weighing sensor 12; If it is necessary to perform a status detection on the carton 100 to be tested, after the carton 100 to be tested is placed, the connecting rod 33 is driven downward by the hydraulic push rod 37, so that the pressure assembly 4 gradually approaches the top of the carton 100 to be tested. At this time, the clamping block 55 at the bottom of the pressure assembly 4 is away from the bottom of the bottom plate 41 under the action of the self-gravity of the slide plate 52, and then the two groups of sliders 51 located at the front and back and left and right are driven to approach each other by the motor B59 outside the bottom plate 41 and the cover plate 43, respectively, so that the slider 51 drives the clamping block 55 to approach the outside of the carton 100 to be tested, and the limit plate 54 located between the slide plate 52 and the clamping block 55 will first be located above the carton 100 to be tested, and gradually fall on the top of the carton 100 to be tested, and then the slider 51 is driven by the motor B59 to continue to approach, so that the clamping block 55 at the bottom of the limit plate 54 drives the carton 100 to be tested to position itself on the top of the detection plate 11; After the carton 100 to be tested is positioned, the bottom plate 41 continues to move downward and is pressed against the top of the carton 100 to be tested. At this time, the limit plate 54 is supported by the carton 100 to move upward relative to the slider 51 until the bottom plate 41 is pressed against the top of the carton 100 to be tested. The limit plate 54 is stored in the storage groove 56, and the clamping block 55 continues to be located on the outside of the carton 100 to be tested, so as to prevent the bottom plate 41 and the carton 100 to be tested from sliding relative to each other during shaking, thereby reducing the detection effect. Finally, the shaking component 2 at the bottom of the test box 1 is used to generate shaking, so that the carton 100 to be tested inside the test box 1 is subjected to shaking detection under a certain pressure. The pressure can be used to simulate the heavy objects stacked on the top of the carton 100 to be tested, and then the load-bearing capacity of the carton 100 to be tested when it is shaken during stacking and transportation can be tested.

[0035] Its advantages are that the detection plate 11 is provided to support the bottom of the carton 100 to be tested, and the pressure component 3 is provided on the top of the detection box 1 to drive the pressure component 4 to approach the top of the carton 100 to be tested, and a certain pressure is generated on the pressure component 4, so that the pressure component 4 is pressed on the top of the carton 100 to be tested as a load, which is used to simulate that a heavy object is stacked on the top of the carton 100 to be tested, and the pressure component 3 can drive the pressure component 4 to exert different pressures on the carton 100 to be tested. On this basis, the shaking component 2 at the bottom of the detection box 1 can drive the carton 100 to be tested to shake, and the carton 100 to be tested is shaken when a load is added to the top of the carton 100 to be tested. , and then simulate the load-bearing capacity of the carton 100 to be tested when it is shaken during the stacking and transportation process; indirectly, by adjusting the pressure of the pressure component 4 on the carton 100 to be tested, and then adjusting the shaking frequency of the shaking component 2, the shaking degree that the carton 100 to be tested can withstand when subjected to different loads can be detected; and when static testing is required, the shaking component 2 located at the bottom of the test box 1 does not need to be operated, and it is only necessary to drive the pressure component 4 to be located at the top of the carton 100 to be tested through the pressure component 3, and gradually apply pressure to the pressure component 4, and use the detection plate 11 to detect the load-bearing condition of the carton 100 to be tested, so as to adapt to different testing conditions; Before the shaking detection, the carton 100 to be tested is automatically positioned by the positioning component 5, and after positioning, the clamping block 55 is located on the outside of the carton 100 to be tested, and the pressure component 4 and the carton 100 to be tested are limited by the clamping block 55 in the horizontal direction to prevent the pressure component 4 from sliding relative to the carton 100 to be tested when the carton 100 is shaken, thereby preventing energy loss; and the clamping block 55 is located near the top of the carton 100 to be tested, and the force-bearing surface on the side of the carton 100 to be tested is small, so as to prevent the carton 100 to be tested from being supported and reinforced by the side of the clamping block 55 during the shaking process and affecting the bearing capacity Test results; when the test result of the carton 100 to be tested changes suddenly, it means that the carton 100 to be tested has been deformed (such as bending or compression at the vertical crease) based on the pressure applied by the pressure component 4; and the inclination angle of the detection box 1 can be adjusted through the eccentric structure in the shaking component 2, so that the detection box 1 drives the carton 100 to be tested to shake at different inclination angles, and the inclination is automatically adjusted during the shaking process, so as to automatically adjust the shaking amplitude during the shaking process, so as to detect the degree of shaking that the carton 100 to be tested can withstand under pressure.

[0036] When the pressurizing component 3 and the pressure applying component 4 in the carton load-bearing detection device of the present application are performing a dynamic detection process: First, the hydraulic push rod 37 drives the connecting frame 32 to move downward, so that the outer side of the connecting rod 33 is close to the top of the carton 100 to be tested through the pressure component 4 suspended by the connecting rod 33, and after the positioning component 5 positions the carton 100 to be tested, it continues to move downward and presses on the top of the carton 100 to be tested. At this time, the connecting frame 32 pushes the ball 34 at the bottom of the connecting rod 33 to be located inside the ball groove 46 at the top of the bottom plate 41. When the detection box 1 is shaken by the driving of the shaking component 2, the connecting rod 33 passes through the pressure component 4 to move the ball 34 to the bottom of the bottom plate 41. The ball 34 is in active contact with the ball groove 46, so that the pressure component 4 has a sliding tendency relative to the carton 100 to be tested when shaking, and the positioning component 5 has an anti-slip effect on the bottom plate 41 and the carton 100 to be tested, so that the sliding tendency of the pressure component 4 acts on the top of the carton 100 to be tested, and is used to force the carton 100 to be tested to deform during the pressure and shaking process, so as to detect the load-bearing capacity of the carton 100 to be tested in a fixed shaking state or the shaking resistance under a fixed load state.

[0037] Among them, when the ball 34 rolls on the inner side of the ball groove 46 relative to the bottom plate 41, since the inner circumference of the ball groove 46 is a slope structure, when the bottom plate 41 is offset and moved a distance, it is blocked by the slope, which can prevent the connecting rod 33 at the top of the ball 34 from hitting the inner wall of the through hole 44 to generate noise, and can also prevent the ball 34 from hitting the inner wall of the ball groove 46 to generate noise, thereby preventing high-frequency noise interference caused by shaking during the detection process; after the detection, the connecting frame 32 is driven upward by the hydraulic push rod 37 again, so that the connecting frame 32 drives the connecting rod 33 to lift the pressure component 4, and at this time the connecting rod 33 drives the ball seat 35 to slide on the inner side of the tapered groove 45. When the ball seat 35 is attached to the inner side of the tapered groove 45, the connecting rod 33 is located at the center of the through hole 44, so that the pressure component 4 is automatically reset after the detection, so as to facilitate the subsequent continuous detection.

[0038] It is worth mentioning that the above installation method has the following advantages: Advantage 1: By setting a bead seat 35 at the bottom of the connecting rod 33, the outer diameter of the bead seat 35 is larger than the inner diameter of the through hole 44, so that the connecting rod 33 can pass through the bead seat 35 to make the pressure component 4 in a suspended state, so as to drive the pressure component 4 to approach the top of the carton 100 to be tested through the pressure component 3, and apply moving pressure to the top of the carton 100 to be tested, so as to provide a load for the load-bearing test of the carton 100 to be tested.

[0039] Advantage two, by arranging the ball 34 on the inner side of the ball seat 35, when the pressure component 3 presses the pressure component 4 on the top of the carton 100 to be tested, the ball 34 is pressed on the top of the bottom plate 41 at the same time, and because the inner diameter of the through hole 44 is larger than the diameter of the connecting rod 33, the pressure component 4 can produce horizontal and vertical displacement relative to the connecting rod 33 during the shaking process. When the pressure component 4 is vertically displaced, it means that the carton 100 to be tested is damaged by deformation. At this time, the detection result of the detection plate 11 changes, so as to obtain the load-bearing capacity of the carton 100 to be tested.

[0040] Advantage three, by setting a ball groove 46 corresponding to the ball 34 on the top of the bottom plate 41, the ball groove 46 limits the displacement range of the pressure component 4 relative to the ball 34, so as to prevent the pressure component 4 from excessively moving so that the inner wall of the through hole 44 collides with the connecting rod 33 and generates noise, thereby reducing the generation of noise and preventing damage and deformation between the two.

[0041] Advantage four, by providing an inclined structure on the inner wall of the bead groove 46, when the pressure component 4 moves so that the inclined structure on the inner side of the bead groove 46 contacts and approaches the ball 34, the impact of the ball 34 is cushioned by the inclined structure, thereby further reducing the generation of noise; and when the inclined structure moves toward the bottom of the ball 34, the pressure of the pressure component 4 on the carton 100 to be tested will increase to a certain extent, and this short-term pressure can be detected by the detection plate 11, which helps the carton 100 to be compressed downward and deformed during the shaking process, making the deformation of the carton 100 to be tested more obvious, which is conducive to observation.

[0042] Advantage five, by setting a ball seat 35 at the bottom of the connecting rod 33 for installing the ball 34, before the pressure assembly 4 is pressed against the carton 100 to be tested, the connecting rod 33 can lift the pressure assembly 4 and move it through the ball seat 35. After the test is completed, the connecting rod 33 can lift the pressure assembly 4 so that the ball seat 35 can slide on the inside of the conical groove 45 to automatically adjust and reset the position of the pressure assembly 4, so that when testing again, the connecting rod 33 is located in the middle of the through hole 44 to ensure the consistency of the moving range of the pressure assembly 4 in each direction.
