Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box technology, and more particularly to a compression resistance testing device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products, including calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are considered green and environmentally friendly products, benefiting both environmental protection and loading / unloading. During the production and processing of corrugated boxes, compression testing is required to monitor their quality.

[0003] Chinese Patent CN220339896U discloses a corrugated cardboard box compression testing device, relating to the field of corrugated cardboard boxes. The device includes a main body with a fixing mechanism at its top. The fixing mechanism includes a rod groove, with two sets of rod grooves containing screws. Screw sleeves are fitted onto the side walls of the screws. Motors are installed on both the left and right side walls of the main body. An electric telescopic rod is located at the top of the screw sleeves. An upper pressure plate is located at the top of the screw sleeves, and a side baffle is located on one side of the bottom end of the upper pressure plate. Both ends of the screw sleeves are tightly attached to the top of the main body. Before compression testing, the corrugated cardboard box can be fixed by the upper pressure plate and the side baffles. This device is not limited by the size of the corrugated cardboard box, thereby improving testing efficiency, facilitating the testing of corrugated cardboard boxes, and improving the production quality of corrugated cardboard boxes.

[0004] The shortcomings of the existing technical solutions are as follows: Corrugated carton compression testing focuses on the compression resistance of empty cartons, supplemented by stacking, pressure holding, and deformation tests. When conducting stacking simulations or pressure holding tests, for multi-layered stacked corrugated cartons or cartons under prolonged pressure, the existing technology relies on manual stacking, which can easily lead to lateral shifting or tipping of the cartons under pressure, affecting the accuracy of the test data. In addition, during the testing process, the existing devices rely heavily on manual observation or a single sensor to monitor the deformation of the cartons after compression, making it difficult to achieve real-time, multi-point accurate acquisition of deformation data for different parts of the cartons. This fails to comprehensively reflect the stress and deformation characteristics of the cartons during the compression process, hindering in-depth analysis and quality assessment of the compression resistance performance of corrugated cartons. Furthermore, when conducting multiple consecutive tests, the loading and unloading operations of the existing devices are relatively cumbersome, lacking automated feeding and unloading mechanisms, resulting in low testing efficiency and making it difficult to meet the rapid testing needs of large-scale production lines.

[0011] As a further embodiment of the present invention: a connecting side plate 1 is fixedly connected to one side of the square frame, and a connecting side plate 2 is fixedly connected to the other side of the square frame.

[0015] The beneficial effects of this invention are: 1. This device can perform multi-layer stacking compression resistance testing of corrugated cartons, adapting to the testing needs of actual carton stacking scenarios in industrial production. During testing, the automated feeding mechanism completes the layer-by-layer stacking of multi-layer corrugated cartons, replacing the tedious manual stacking operation and avoiding problems such as carton misalignment and uneven stacking caused by manual stacking. During the stacking test, the top pressure mechanism maintains the top pressure plate horizontal through the sliding cooperation of the mechanism sleeve and the connecting rod, providing uniform and stable vertical pressure to the multi-layer stacked cartons, effectively preventing lateral misalignment and tilting of cartons during traditional stacking tests, and ensuring the authenticity of the stacking pressure test data. At the same time, the scanning imager can perform overall scanning and compression deformation monitoring of multi-layer stacked cartons, accurately capturing the overall and local deformation characteristics of the cartons under stacking conditions, filling the gap in deformation monitoring in traditional stacking tests, and providing complete data for stacking compression resistance performance evaluation.

[0016] 2. The lifting mechanism of this device, through the cooperation of threaded rods and sliding rods, drives the square frame to rise and fall smoothly, simultaneously achieving two major functions: First, the square frame is directly fixedly connected to the mechanism fixing plate of the feeding mechanism. Therefore, the lifting mechanism can drive the entire feeding mechanism to move up and down, flexibly adjusting the picking and placing height of the feeding fixture according to the number of carton layers and height of the stacking test, accurately completing the layer-by-layer feeding and stacking of multi-layer cartons, adapting to the feeding needs of stacking at different heights; Second, the square frame integrates guide rails, a moving trolley, and a scanning imager. The lifting mechanism can drive the scanning imager to move up and down synchronously, accurately adjusting the scanning height. It can complete the baseline scanning of the initial stacking state of single-layer / multi-layer cartons, and can also adjust the scanning position in real time according to the height of the carton sinking under pressure during the stacking top pressure test, achieving accurate scanning and detection of the pressure-stacked cartons. No additional imager adjustment mechanism is required, making the structural design more ingenious.

[0017] 3. The lifting mechanism and the top-pressing mechanism work in precise coordination. After the scanning imager completes the initial scanning of the carton (single-layer / multi-layer stacking), the lifting mechanism can move the square frame and imager down to reset, completely avoiding the downward pressure detection path of the top-pressing mechanism and preventing interference with the top-pressing and stacking tests. When real-time deformation scanning of the compressed carton (stacked / single-layer) is required during the top-pressing test, the lifting mechanism can again move the imager precisely to the detection height, cooperating with the moving carriage to achieve all-round scanning. After scanning, it can quickly rise again without affecting the continuous top-pressing test. The action connection of the two mechanisms is uniformly controlled by the controller, which is seamless and automated. At the same time, the pressure data collected in real time by the pressure sensor of the top-pressing mechanism and the deformation data of the scanning mechanism can be synchronously transmitted to the controller, realizing synchronous monitoring and data integration analysis of pressure and deformation in stacking / compression testing, resulting in more comprehensive test data.

A moving trolley 6 is slidably set on the guide rail 5. A mounting frame 7 is fixedly connected to the upper surface of the moving trolley 6. A scanning imager 8 is fixedly connected to the upper end of the mounting frame 7. A support frame 22 is fixedly connected to the base 1 on one side of the square frame 4.

A top pressure mechanism 26 is provided at the driving end of the top pressure cylinder 24. The feeding mechanism 27 includes a mechanism fixing plate 271, which is fixedly connected to the other side of the square frame 4. A support base 272 is fixedly connected to the upper surface of the mechanism fixing plate 271. A fixed arm 273 is fixedly connected to the upper end of the support base 272. A swing arm 275 is rotatably connected above the fixed arm 273. A mechanism motor 274 for driving the swing arm 275 to swing is provided on the fixed arm 273. A fixed frame 276 is fixedly connected to the upper surface of the swing arm 275. A mechanism cylinder 277 is provided on the fixed frame 276. A feeding clamp 279 is provided at the driving end of the mechanism cylinder 277.

[0024] One end of the bottom surface of the fixed arm 273 is fixedly connected to the support base 272. The swing arm 275 is rotatably connected to the upper end of the fixed arm 273 away from the support base 272. The fixed frame 276 is located at the upper end of the swing arm 275 away from the mechanism motor 274. The mechanism cylinder 277 is horizontally arranged. A telescopic rod 278 is provided on the drive end of the mechanism cylinder 277. The telescopic rod 278 is fixedly connected to the feeding clamp 279. A swing shaft is provided on the drive end of the mechanism motor 274. The swing shaft is fixedly connected to the swing arm 275. When the mechanism motor 274... When started, its drive end drives the swing shaft to rotate, which in turn drives the swing arm 275 to swing around the rotation connection point with the fixed arm 273 as the axis. After the mechanism cylinder 277 is started, the extension and retraction of the telescopic rod 278 can drive the loading clamp 279 to move in the horizontal direction, so as to accurately clamp the corrugated carton to be inspected or place the inspected corrugated carton in a designated position. The clamping action of the loading clamp 279 can be realized by its own drive component (such as a small cylinder or electric gripper) to ensure reliable gripping and release of the corrugated carton.

[0025] The lifting mechanism includes a lifting assembly and a limiting assembly. The lifting assembly includes a horizontally arranged mounting base plate 13, which is fixedly connected to the base 1. A vertically arranged support plate 14 is fixedly connected to the upper surface of the mounting base plate 13. A horizontally arranged mounting top plate 15 is fixedly connected to the upper end of the support plate 14. A threaded rod 17 is rotatably arranged between the mounting top plate 15 and the mounting base plate 13. A drive motor 16 is arranged on the upper surface of the mounting top plate 15. A drive shaft is arranged on the drive end of the drive motor 16. The drive shaft is coaxially fixedly connected to the threaded rod 17. The limiting assembly includes a horizontally arranged mounting base plate 18, which is fixedly connected to the base 1. A vertically arranged support plate 19 is fixedly connected to the upper surface of the mounting base plate 18. A horizontally arranged mounting top plate 20 is fixedly connected to the upper end of the support plate 19. A sliding rod 21 is fixedly connected between the mounting top plate 20 and the mounting base plate 18.

[0026] A connecting side plate 9 is fixedly connected to one end of the square frame 4, and a connecting side plate 11 is fixedly connected to the other end of the square frame 4. A threaded sleeve 10 is embedded through the connecting side plate 9, and the threaded sleeve 10 is fitted and threadedly connected to the threaded rod 17. A sliding sleeve 12 is embedded through the connecting side plate 11, and the sliding sleeve 12 is movably fitted onto the sliding rod 21. When the drive motor 16 starts, its drive end drives the drive shaft to rotate, thereby driving the threaded rod 17 to rotate synchronously. Since the threaded sleeve 10 is threadedly connected to the threaded rod 17... Furthermore, the connecting side plate 9 is fixedly connected to the square frame 4, while the sliding sleeve 12 on the connecting side plate 11 is fitted onto the sliding rod 21. The sliding rod 21 guides and limits the sliding sleeve 12, restricting the rotational freedom of the square frame 4. Therefore, when the threaded rod 17 rotates, the threaded sleeve 10 cannot rotate with the threaded rod 17, but can only move up and down along the axial direction of the threaded rod 17, thereby driving the connecting side plate 9, the square frame 4, and the connecting side plate 11 as a whole to smoothly rise and fall along the axial direction of the sliding rod 21. By controlling the forward and reverse rotation of the drive motor 16, the rising and falling movements of the square frame 4 can be achieved.

[0027] The pressing mechanism 26 includes a mechanism connecting plate 261. Mechanism sleeves 262 are fixedly connected to the mechanism connecting plate 261 near its four corners. A connecting rod 263 is movably fitted inside the mechanism sleeve 262. A limit block 264 is fixedly connected to the upper end of the connecting rod 263, and a pressing plate 266 is fixedly connected to the lower end of each connecting rod 263. A pressure sensor 265 is embedded in the lower end face of the mechanism connecting plate 261. A telescopic rod 25 is provided at the driving end of the pressing cylinder 24. The telescopic rod 25 is fixedly connected to the upper end face of the mechanism connecting plate 261. When the pressing cylinder 24 drives the telescopic rod 25 to extend downwards, the mechanism connecting plate 261 moves downwards accordingly. At this time, the connecting rod... The connecting rod 263 slides downwards synchronously within the mechanism sleeve 262. The top pressure plate 266 first contacts the top surface of the corrugated carton. As the top pressure cylinder 24 continuously applies pressure, the top pressure plate 266 experiences a reaction force from the carton. This reaction force is transmitted to the pressure sensor 265 via the connecting rod 263. The pressure sensor 265 converts the sensed pressure signal into an electrical signal in real time and transmits it to the control system of the device, allowing operators to monitor the pressure value borne by the corrugated carton in real time. During the pressing process, the limiting block 264 effectively prevents the connecting rod 263 from slipping out of the mechanism sleeve 262, ensuring the stability and safety of the pressing mechanism 26. The lower end face of the top pressure plate 266 is designed to be flat and smooth to ensure uniform contact between it and the top surface of the corrugated carton, thereby ensuring the accuracy of the pressure detection results.

[0028] A controller 2 is installed on the front panel of the base 1. The controller 2 is electrically connected to the mobile trolley 6, the scanning imager 8, the drive motor 16, the top pressure cylinder 24, the pressure sensor 265, the mechanism motor 274, and the mechanism cylinder 277. The scanning imager 8 is a structured light 3D camera. By setting the controller 2, the automated control and data integration of each component can be realized. It has a preset control program that can automatically adjust the operating parameters of each mechanism according to the detection requirements.

[0029] Workflow: When using the compression testing device for corrugated cardboard box production, the device is first started by the controller 2. The corrugated cardboard box to be tested is placed in the feeding area of ​​the feeding mechanism 27. At this time, the mechanism motor 274 starts after receiving the instruction from the controller 2. The swing shaft at its drive end drives the swing arm 275 to swing outward around the rotational connection with the fixed arm 273 until the feeding clamp 279 moves to both sides of the corrugated cardboard box. Then, the mechanism cylinder 277 is activated, driving the telescopic rod 278 to extend, so that the feeding clamp 279 clamps and fixes the corrugated cardboard box. Next, the mechanism motor 274 rotates in the opposite direction, driving the swing arm 275 to swing inward and towards the testing table 3, transporting the corrugated cardboard box to the center position above the testing table 3. The mechanism cylinder 277 is activated again, the telescopic rod 278 retracts, the feeding clamp 279 is released, and the corrugated cardboard box is placed stably on the testing table 3, completing the feeding process.

[0030] After the material is loaded, the controller 2 controls the lifting mechanism to start working, the drive motor 16 starts, and its drive shaft drives the threaded rod 17 to rotate between the mounting top plate 15 and the mounting bottom plate 13. Since the threaded sleeve 10 is threadedly connected to the threaded rod 17, and the connecting side plate 9 is fixed to the square frame 4, and the sliding sleeve 12 on the connecting side plate 11 slides on the sliding rod 21, it plays a limiting and guiding role in the lifting of the square frame 4. Therefore, the rotation of the threaded rod 17 drives the square frame 4 to descend vertically until the lens of the scanning imager 8 is aligned with the corrugated carton on the inspection table. Then, the moving trolley 6 moves along the extension trajectory of the square frame 4 on the guide rail 5, driving the scanning imager 8 to perform a full-range scanning image of the surface of the corrugated carton. The scanning data is transmitted to the controller 2 in real time. The controller 2 records the initial external dimensions, surface flatness and other information of the carton, providing reference data for subsequent deformation analysis.

[0031] After scanning, the lifting mechanism lowers and resets the square frame 4 to avoid interference with the top pressure detection. Then, the top pressure cylinder 24 activates, driving the telescopic rod 25 to extend downwards, moving the top pressure plate 266 downwards. Before the top pressure plate 266 contacts the top surface of the corrugated carton, the connecting rod 263 inside the mechanism sleeve 262 can move freely. When the top pressure plate 266 contacts the top surface of the carton and continues to move downwards, the pressure sensor 265 begins to contact and sense the pressure. At this time, the top pressure cylinder 24 continuously applies pressure, and the top pressure plate 266... The corrugated cardboard box is pressed down. During the pressing process, the pressure sensor 265 monitors the pressure value in real time and feeds it back to the controller 2. At the same time, if a pressure holding test is performed, the pressing cylinder 24 can maintain the current pressure state. The controller 2 records the pressure holding time and the pressure change during the process. For stacking simulation test, the corrugated cardboard box can be stacked multiple times and then pressed down. Under the action of pressure, the cooperation between the mechanism sleeve 262 and the connecting rod 263 can ensure that the pressing plate 266 always remains horizontal and provides stable downward pressure.

[0032] During the top-pressure testing process, if it is necessary to monitor the deformation of the corrugated carton, the lifting mechanism can be moved again to allow the scanning imager 8 to scan the carton in real time during the pressure process. The moving trolley 6 drives the scanning imager 8 to repeatedly move the scanning path, transmitting the scanned images at different times to the controller 2. The controller 2 calculates parameters such as the amount of deformation and the rate of deformation at different parts of the carton by comparing the initial image with the real-time scanned image, realizing multi-point, real-time deformation monitoring. After the test is completed, if the carton is not damaged, the top-pressure cylinder 24 drives the top-pressure mechanism 26 to rise and reset, and the feeding mechanism 27 operates again to remove the tested carton from the testing table 3 and transport it to the designated area. If the carton is damaged during the test, the controller 2 records the pressure value, deformation amount, and other data at the time of damage and issues a prompt through the alarm module, so that the staff can handle it in time. Throughout the entire testing process, all data is integrated, analyzed, and stored by the controller 2 for subsequent quality assessment and data analysis.
