[0009] As a further scheme of the present application, the driving assembly comprises two transmission wheels, the ends of the two transmission wheels are rotatably connected to one side of one of the baffles through shaft sleeves, a transmission belt is sleeved on the two transmission wheels, a first fixed block and a second fixed block are fixed to one side of the top of the transmission belt and one side of the bottom of the transmission belt respectively, the first fixed block is fixed to one side of the bottom of the second workbench, the second fixed block is fixed to one side of the sliding plate, one end of one of the transmission wheels penetrates the baffle and is fixed with a motor, and the motor is fixed to the outer side of the baffle.

[0011] As a further scheme of the present application, the adjusting assembly comprises a rotating shaft, the rotating shaft is installed in the middle of the mounting seat through a shaft sleeve, the top end of the rotating shaft penetrates the mounting seat and is fixed to the bottom of the deflector disc, a supporting bearing is sleeved on the bottom end of the rotating shaft, the supporting bearing is clamped to the bottom of the inner wall of the recess, a fixed ring is fixed to the top of the outer wall of the rotating shaft, a torsional spring is fixed to the bottom of the fixed ring, a partition ring is fixed to the bottom end of the torsional spring, the partition ring is fixed to the inner wall of the recess, the rotating shaft penetrates the partition ring, an extension rod is fixed to the lower part of the outer wall of the rotating shaft, and the end of the extension rod penetrates the deflection groove and is fixed with a handle.

[0012] A detection method of a protective carton compression load detection device, the detection method comprising the following steps: When the compression resistance of the carton is detected, the handle on the second workbench is held and pulled clockwise, so that the handle drives the extension rod to slide in the deflection groove, and the other end of the extension rod drives the rotating shaft to rotate clockwise. In the process of rotating the rotating shaft, the fixed ring is twisted to twist the torsional spring. At the same time, the top end of the rotating shaft drives the deflection disc to rotate. Since the deflection disc and the material supporting plate are connected by the shaft sleeve, the deflection disc cannot drive the material supporting plate to rotate synchronously. In the process of rotating the deflection disc, the four supporting rods push the four sliding blocks away from each other, so that the sliding blocks slide in the sliding groove. The sliding groove with T-shaped design limits the sliding blocks, so that the sliding blocks will not come off the sliding groove in the process of sliding, and the stability of the supporting rods driving the blocking rods to move is improved. In this process, the four sliding blocks drive the four blocking rods away from each other to expand the space range between the four blocking rods. Secondly, the carton to be detected is placed on the material supporting plate. In the process of loosening the handle, the force of the torsional spring drives the rotating shaft to rotate through the fixed ring, so that the rotating shaft drives the deflection disc to rotate counterclockwise. The deflection disc synchronously pulls the supporting rods, so that the four supporting rods drive the four sliding blocks and the four blocking rods to move close to each other. Until the four blocking rods contact the outer wall of the carton, the function of limiting the carton is realized, which prevents the carton from deviating and coming off the material supporting plate under subsequent pressure. After the limiting and clamping work of the carton is completed, the motor is started, so that the output shaft of the motor drives the transmission wheel to rotate counterclockwise. The transmission wheel drives the conveying belt to work. Since the first fixed block is fixed on one side of the bottom of the second workbench, and the second fixed block is fixed on one side of the sliding plate, the top of the transmission belt drives the second workbench to move left through the first fixed block. The sliding table at the bottom of the second workbench slides in the track on the baffle, which improves the stability of the horizontal movement of the carton above the second workbench. The bottom of the transmission belt drives the sliding plate to move right through the second fixed block, so that the sliding plate drives the first workbench to move right through the four sliding rods. The first workbench drives the four sliding rods to slide up and down on the sliding plate through the vertical plate at the bottom, which improves the stability of the vertical movement of the first workbench. In this process, the first workbench moves to the lower side of the second workbench. When the second workbench moves to the inside of the detection support, the sliding column slides into the highest point in the slide, and the vertical plate drives the first workbench to lift up, so that the first workbench and the second workbench are alternately positioned, so as not to interfere with the stroke of the first workbench and the second workbench. At this time, the carton on the second workbench is below the detection assembly, the electric hydraulic telescopic rod is controlled to extend and drive the adjusting plate to move downwards, the adjusting plate drives the pressure sensor to move downwards and apply pressure to the top of the carton, and the applied pressure value is monitored, since four cameras are installed at equal intervals at the edge of the bottom of the adjusting plate, and the included angle between adjacent two cameras is ninety degrees, the multiple cameras can real-time shoot and record the surface deformation and damage of the carton in the pressure process, combined with an image recognition algorithm, the damage position and degree of the carton are automatically analyzed, when obvious damage of the carton is detected or the preset pressure limit value is reached, the electric hydraulic telescopic rod stops pressing, the detection is completed, and then the electric hydraulic telescopic rod is retracted and drives the pressure sensor to move upwards through the adjusting plate, so that the pressure sensor is away from the carton, in the detection process, the handle on the first workbench is held and twisted clockwise, and the carton to be detected is installed on the material supporting plate on the first workbench; After the detection work of the carton on the second workbench is completed, the motor is controlled to work, so that the output shaft of the motor drives the transmission wheel to rotate clockwise, and in this process, the top of the transmission belt drives the second workbench to move rightwards through the first fixed block, and the bottom of the transmission belt drives the first workbench to move leftwards through the second fixed block, so that the first workbench drives the clamped carton to move to below the detection assembly for detection, and the second workbench moves the detected carton to the right side, when the carton is detached, the handle is held and twisted clockwise, the other end of the extension rod drives the rotating shaft to rotate clockwise, the top end of the rotating shaft drives the deflector disc to rotate, and the deflector disc drives the four sliding blocks and the blocking rods to move away from each other through the four supporting rods in the rotating process, so that the blocking rods are away from the carton, so that the detected carton can be detached.

[0013] Compared with the prior art, the present application has the following advantages: 1. This invention uses a second fixed block to move the sliding plate to the right, which in turn moves the first worktable to the right via four sliding rods. The first worktable, through a bottom upright plate, moves a sliding column in an inverted V-shaped track. When the sliding column reaches the lowest point of the track, it pulls the first worktable downwards via the upright plate. During this process, the first worktable moves below the second worktable. When the second worktable moves into the detection bracket, the sliding column slides into the highest point of the track, and the upright plate lifts the first worktable, allowing the first and second worktables to interchange positions, thus preventing damage to the first worktable and the second worktable. The travel of the second workbench causes interference. The cartons on the second workbench are located below the detection component and are being detected. During the detection process, the cartons to be tested are installed on the first workbench. After the detection of the cartons on the second workbench is completed, the drive component is controlled to work, so that the first workbench moves the clamped cartons to the bottom of the detection component for detection. The second workbench moves the detected cartons to the right side. By using a multi-station alternating feeding and detection method, the detection efficiency is improved, so that the overall detection speed is not limited by the pressure test time, thereby meeting the high-throughput detection requirements of modern production lines. 2. This invention involves placing the carton to be tested on a support plate. During the release of the handle, the force of the torsion spring drives the rotating shaft to rotate via the fixing ring. This rotating shaft then drives the deflector to rotate counterclockwise. Simultaneously, the deflector pulls the support rods, causing the four support rods to drive the four sliders and four stop rods closer together until the four stop rods contact the outer wall of the carton. This limits the carton's position, preventing it from shifting under subsequent pressure and detaching from the support plate. Furthermore, the movement of the stop rods pushes the carton towards the center of the support plate. Because of the four stop rods... The flexible support for the cardboard box prevents deformation or damage caused by excessive clamping force, thus protecting the box and improving the stability and accuracy of subsequent inspections. When removing the box, hold the handle and turn it clockwise. The other end of the extension rod drives the rotating shaft to rotate clockwise. The top of the rotating shaft drives the deflector to rotate. During the rotation, the deflector pushes the four sliders and the stop rods away from each other through the four support rods, making it easier to remove the inspected box and improving the convenience of changing boxes.

A testing method for a protective cardboard box compression load-bearing capacity testing device, wherein the protective cardboard box compression load-bearing capacity testing device according to any one of claims 1-7 is characterized in that, The detection method includes the following steps: When testing the compressive strength of the carton, hold the handle (167) on the second workbench (5) and turn it clockwise. This causes the handle to slide the extension rod (166) within the deflection groove (14). The other end of the extension rod (166) then drives the rotating shaft (161) to rotate clockwise. During the rotation of the rotating shaft (161), the torsion spring (164) is torn through the fixed ring (163). At the same time, the top of the rotating shaft (161) drives the deflection disk (155) to rotate. Due to the deflection disk ( The deflector (155) is rotatably connected to the support plate (151) via a bushing, so that the deflector (155) will not drive the support plate (151) to rotate synchronously. During the rotation of the deflector (155), the four sliders (153) are pushed away from each other by the four support rods (152), so that the sliders (153) slide in the groove (12). The T-shaped groove (12) limits the sliders (153) so that the sliders (153) will not fall out of the groove (12) during the sliding process. To improve the stability of the movement of the support rod (152) and the stop rod (154), during this process, the four sliders (153) drive the four stop rods (154) to move away from each other, thereby expanding the space between the four stop rods (154). Next, the carton to be tested is placed on the material tray (151). During the process of releasing the handle (167), the force of the torsion spring (164) drives the rotating shaft (161) to rotate through the fixed ring (163), so that the rotating shaft (161) drives the deflection disk. (155) Rotate counterclockwise, and the deflector (155) will simultaneously pull the support rod (152), so that the four support rods (152) will drive the four sliders (153) and the four stop rods (154) to move closer to each other until the four stop rods (154) contact the outer wall of the carton, which will limit the carton and prevent the carton from shifting under pressure and thus detaching from the material support plate (151). Moreover, during the movement of the stop rods (154), the carton will be pushed towards the center of the material support plate (151). After completing the limiting and clamping work of the carton, the motor (105) is started, so that the output shaft of the motor (105) drives the transmission wheel (101) to rotate counterclockwise. The transmission wheel (101) then drives the conveyor belt to work. Since the first fixing block (103) is fixed to one side of the bottom of the second workbench (5) and the second fixing block (104) is fixed to one side of the slide plate (601), the top of the transmission belt (102) drives the second workbench (5) to move to the left through the first fixing block (103). The slide at the bottom of the second workbench (5) slides in the track on the baffle (1), improving the stability of the second workbench (5) driving the carton above to move horizontally. The bottom of the transmission belt (102) drives the slide plate (601) to move to the right through the second fixing block (104), so that the slide plate (601) drives the first workbench (4) to move to the right through the four slide rods (603). The first worktable (4) is driven by the bottom plate (7) to slide the sliding column (8) in the inverted V-shaped slide (904). When the sliding column (8) slides to the lowest point in the slide (904), the sliding column (8) pulls the first worktable (4) down through the plate (7). The first worktable (4) then drives the four sliding rods (603) to slide down the slide plate (601), improving the stability of the vertical movement of the first worktable (4). During this process, the first worktable (4) moves to the bottom of the second worktable (5). When the second worktable (5) moves into the detection bracket (2), the sliding column (8) slides into the highest point in the slide (904), and the plate (7) drives the first worktable (4) to lift up, so that the first worktable (4) and the second worktable (5) are interchanged, so as not to interfere with the stroke of the first worktable (4) and the second worktable (5). At this time, the carton on the second workbench (5) is located below the detection component (3). By controlling the extension of the electric hydraulic telescopic rod (301) and driving the adjusting plate (302) to move down, the adjusting plate (302) drives the pressure sensor (303) to move down and apply pressure to the top of the carton. At the same time, the applied pressure value is monitored. Since four cameras (304) are installed at equal intervals on the bottom edge of the adjusting plate (302), and the angle between two adjacent cameras (304) is ninety degrees, multiple cameras (304) can capture real-time images of the surface deformation and damage of the carton during the pressure process. Record, combine image recognition algorithm, automatically analyze the location and degree of damage of carton. When the carton is found to be obviously damaged or reaches the preset pressure limit value, the electric hydraulic telescopic rod (301) stops pressurizing and the detection ends. Then the electric hydraulic telescopic rod (301) retracts and drives the pressure sensor (303) to move up through the adjustment plate (302) so that the pressure sensor (303) is away from the carton. During the detection process, hold the handle (167) on the first workbench (4) and turn it clockwise. Similarly, the carton to be detected is installed on the material support plate (151) on the first workbench (4). After completing the inspection of the cartons on the second workbench (5), the control motor (105) is activated, causing the output shaft of the motor (105) to drive the transmission wheel (101) to rotate clockwise. Similarly, during this process, the top of the transmission belt (102) drives the second workbench (5) to move to the right through the first fixing block (103), and the bottom of the transmission belt (102) drives the first workbench (4) to move to the left through the second fixing block (104), so that the first workbench (4) moves the clamped cartons to the area below the inspection assembly (3) for inspection. The second workbench (5) transfers the tested cardboard box to the right side. When removing the cardboard box, hold the handle (167) and turn it clockwise. The other end of the extension rod (166) drives the rotating shaft (161) to rotate clockwise. The top of the rotating shaft (161) drives the deflection disk (155) to rotate. During the rotation, the deflection disk (155) pushes the four sliders (153) and the stop bar (154) away from each other through the four support rods (152), so that the stop bar (154) is away from the cardboard box, so that the tested cardboard box can be removed.
