Description

Technical Field

[0001] This utility model relates to the field of tumbling quality inspection equipment, specifically to an automatic tumbling test device for packaging boxes. Background Technology

[0002] Corrugated cardboard boxes are one of the most widely used packaging materials. The number of corrugated layers and the height of the corrugations have different effects on the compressive strength of the cardboard boxes. To ensure the safety and reliability of different transported goods, corrugated cardboard boxes with corresponding compressive strength are required. The compressive strength of the cardboard boxes directly affects the packaging quality, so the compressive strength of the cardboard boxes needs to be inspected after production. Therefore, a compressive strength inspection device is needed. The current tumbling test requires placing the packaging box on an impact plane. The operator pushes the packaging box over from the initial position (one designated side on the ground) by manually rolling it, so that each test surface is impacted in turn until the predetermined number of tumblings is completed, which requires eight tumblings. However, the tumbling test conducted by this method has problems such as uncontrollable tumbling force and speed, inconsistent impact points, difficulty in data recording and traceability, and high labor intensity for operators.

[0003] For example, Chinese patent document CN117268935A discloses a multi-directional pressure-bearing capacity inspection device for corrugated cardboard boxes. This device uses a power board connected to two electromagnetic plates via wires. Each electromagnetic plate has a slide rail at its bottom, and a magnetic slider is connected to the inner wall of the slide rail. Two fixed frames are connected to the top of the magnetic slider via two connecting plates. A drive gear rotates multiple driven gears on the outer side, changing the angle of the extended arc plate and adjusting different pressure-bearing points on the box for testing, thus broadening the pressure-bearing testing surface of the corrugated cardboard box. A piston rod and an outer expansion plate push outward to test the pressure resistance of the inner side of the box. A hydraulic cylinder tests the upper and lower pressure and the inner pressure of the box. However, this patent cannot test the load-bearing capacity of the packaging box during transportation and flipping after loading goods, including at the corners. Utility Model Content

[0004] The present invention aims to provide an automatic tumbling test device for packaging boxes, so as to provide a device for testing the pressure resistance of packaging boxes during the tumbling process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic tumbling test device for packaging boxes, including a flip panel, two limiting clamps symmetrically arranged at the front and rear of the flip panel, a limiting component under the flip panel to drive the limiting clamps to slide relative to each other in the front and rear directions, a flip cylinder for pushing the packaging box to rotate is provided at the bottom of one side of the flip panel, the output end of the flip cylinder can pass through the flip panel and contact the packaging box, a reset cylinder for pushing the packaging box to reset is also provided on the other side of the flip panel, and a turntable for driving the packaging box to rotate is also provided in the middle of the flip panel.

[0006] The beneficial effects of this plan are: In this technical solution, a limiting component is set to allow the limiting clamps to slide relative to each other in the front and back directions. During use, the packaging box is placed on the flip panel, and the limiting clamps slide to limit the packaging box. After limiting, the flip cylinder pushes the packaging box to flip, and the bottom and edges of the packaging box collide with the flip panel to achieve the roll detection of the first side. After the packaging box flips, a reset cylinder is set on the other side to push the packaging box to reset, so that the packaging box moves back to the pushing area of ​​the flip cylinder and repeats the above process. When the number of flips reaches the set number, the reset cylinder pushes the packaging box to reset, and the limiting clamps slide in the opposite direction. Then, the turntable drives the packaging box to rotate 90 degrees and repeats the above process to continue the flip test, so that the other two sides of the packaging box also roll in sequence, completing the roll detection of all six sides of the packaging box.

[0007] By symmetrically arranging two sets of sliding limiting clamps on the front and back of the flip panel, and cooperating with the limiting component to control the relative sliding of the limiting clamps, the device can achieve adaptive limiting and positioning according to packaging boxes of different sizes. This structure effectively constrains the packaging box during the tumbling process, preventing it from tipping over or shifting, thereby ensuring a consistent tumbling direction and making the detection process more stable and controllable.

[0008] This solution designs a dedicated automatic tumbling test device for packaging boxes that can be integrated with packaging production lines for real-time online monitoring. It is convenient, safe, and highly automated. The device can complete tumbling tests on all six sides in a single clamping operation, comprehensively simulating the stress state during transportation and improving the authenticity and completeness of the test. The test results are highly repeatable, comparable, and reliable, effectively eliminating test errors caused by manual tumbling. It is adaptable to packaging boxes of different sizes and weights and effectively improves space utilization.

[0009] Preferably, as an improvement, a support plate is provided below the flip panel. The limiting component includes a lead screw, a motor that drives the lead screw to rotate, and a lifting slider that slides with the lead screw. The limiting component is installed on the support plate and the lead screw is perpendicular to the upper surface of the support plate. Limiting blocks are provided on both the front and rear sides of the lifting slider. A connecting rod is hinged to the opposing surfaces of the two limiting blocks. The support plate is also provided with two sliding limiting rods with axes parallel to the front and rear directions. Two horizontal sliders are provided, each sliding with the two sliding limiting rods. The top of each horizontal slider is fixedly connected to a limiting clamp. The other ends of the two connecting rods are hinged to a horizontal slider.

[0010] The beneficial effects are as follows: The limiting assembly is installed on the support plate below the flip panel. The motor drives the lead screw to rotate, causing the lifting slider to move up and down. Through the geometric transmission of the linkage mechanism, under the limitation of the sliding limit rod, the vertical motion is converted into the synchronous translation of the horizontal slider. The two horizontal sliders move smoothly under the guidance of the sliding limit rod, realizing the symmetrical opening and closing of the limiting clamps, thereby achieving adjustable and symmetrical limiting of the packaging box. When the lead screw moves up and down, the limiting clamps on both sides move at the same speed and in opposite directions, so that the packaging box is subjected to uniform force during limiting, avoiding box tilting or rolling direction deviation caused by unilateral clamping, and improving the accuracy of testing.

[0011] Preferably, as an improvement, a U-shaped plate is provided on the motor, the U-shaped plate has a through hole for the lead screw to pass through, and a guide rod is vertically fixed on the upper surface of the U-shaped plate. The guide rod is parallel to the lead screw and slides with the lifting slider.

[0012] The beneficial effects are as follows: The guide rod, vertically fixed on the U-shaped plate, is set parallel to the lead screw and slides in cooperation with the lifting slider, providing additional guiding constraints during the up-and-down movement of the lifting slider driven by the lead screw. This prevents the lifting slider from tilting or rotating due to force deviation during up-and-down movement, making the motion trajectory more stable and avoiding jamming. By setting a U-shaped plate above the motor to form a cover structure, dust, debris, or packaging box droplets can be effectively prevented from entering the motor and lead screw drive area, avoiding transmission obstruction or motor failure caused by debris accumulation, thereby improving the reliability and service life of the equipment.

[0013] Preferably, as an improvement, a limiting frame is provided on both the front and rear sides of the U-shaped plate, and each limiting frame is provided with at least one sliding groove in the vertical direction, and the two limiting blocks are respectively slidably engaged with a limiting frame in the vertical direction.

[0014] The beneficial effects are: the structure can accurately guide the up and down movement of the limit block, preventing it from shaking or deviating during the screw drive process, thereby maintaining the vertical stability of the limit block's movement.

[0015] Preferably, as an improvement, the sliding limit rods are provided with supports at both ends, and both sliding limit rods are connected to the support plate through the supports.

[0016] The beneficial effects are: the support provides reliable support and fixation for the limit rod, which can disperse the dynamic load transmitted by the horizontal slider and reduce the vibration and fatigue stress of the limit rod during repeated opening and closing actions.

[0017] Preferably, as an improvement, the end of the tilting cylinder is fixed to the support plate, and the tilting cylinder and the support plate form a certain angle.

[0018] The beneficial effects are as follows: the end of the flipping cylinder is fixed to the support plate and forms a certain angle with the support plate, so that when the cylinder output end pushes the packaging box, it can act on the bottom or side edge of the packaging box in an inclined direction, thereby forming a compound thrust with both horizontal and vertical components, and realizing a more natural flipping action of the packaging box.

[0019] Preferably, as an improvement, two connecting rods are fixed on each limiting clamp, and the horizontal sliders are fixedly connected to the corresponding limiting clamps through the connecting rods. A through groove is provided on the flip panel for the connecting rods to slide back and forth.

[0020] The beneficial effects are as follows: the horizontal slider is connected to the limit clamping plate through the connecting rod, and when the motor drives the lead screw to move the lifting slider, the opening and closing of the limit clamping plate is realized through the connecting rod mechanism.

[0023] The following detailed description is provided through specific implementation methods and examples: The preferred embodiments of this utility model are basically as shown in the appendix. Figure 1-5 As shown, Figure 1The automatic tumbling test device for packaging boxes shown includes a flip panel 1. Two limiting clamps 2 are symmetrically arranged at the front and back of the flip panel 1. A limiting component is provided under the flip panel 1 to drive the limiting clamps 2 to slide relative to each other in the front and back directions. A flip cylinder 3 for pushing the packaging box to rotate is provided at the bottom of one side of the flip panel 1. The output end of the flip cylinder 3 can pass through the flip panel 1 and contact the packaging box. A reset cylinder 4 for pushing the packaging box to reset is also provided on the other side of the flip panel 1. A turntable 5 for driving the packaging box to rotate is also provided in the middle of the flip panel 1.

[0024] In this technical solution, a limiting component is set to allow the limiting clamps 2 to slide relative to each other in the front and back directions. During use, the packaging box is placed on the flip panel 1, and the limiting clamps 2 slide to limit the packaging box. After limiting, the flip cylinder 3 pushes the packaging box to flip, and the bottom and edges of the packaging box collide with the flip panel 1 to achieve the roll detection of the first side. After the packaging box flips, the reset cylinder 4 on the other side pushes the packaging box to reset, so that the packaging box moves back to the pushing area of ​​the flip cylinder 3 and repeats the above process. When the number of flips reaches the set number, the reset cylinder 4 pushes the packaging box to reset, and the limiting clamps 2 slide in the opposite direction. The turntable 5 drives the packaging box to rotate 90 degrees and repeats the above process to continue the flip test, so that the other two sides of the packaging box also roll in turn, completing the roll detection of the six sides of the packaging box.

[0025] By symmetrically arranging two sets of sliding limiting clamps 2 on the front and back of the flip panel 1, and cooperating with the limiting component to control the relative sliding of the limiting clamps 2, the device can achieve adaptive limiting positioning according to packaging boxes of different sizes. This structure effectively constrains the packaging box during the tumbling process, preventing it from tipping over or shifting, thereby ensuring a consistent tumbling direction and making the detection process more stable and controllable.

[0026] This solution designs a dedicated automatic tumbling test device for packaging boxes that can be integrated with packaging production lines for real-time online monitoring. It is convenient, safe, and highly automated. The device can complete tumbling tests on all six sides in a single clamping operation, comprehensively simulating the stress state during transportation and improving the authenticity and completeness of the test. The test results are highly repeatable, comparable, and reliable, effectively eliminating test errors caused by manual tumbling. It is adaptable to packaging boxes of different sizes and weights and effectively improves space utilization.

[0027] like Figure 2 and Figure 4As shown, to ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this utility model is as follows: a support plate 6 is fixedly installed below the flip panel 1. The limiting assembly includes a lead screw 7, a motor 9 that drives the lead screw 7 to rotate, and a lifting slider 10 that slides with the lead screw 7. The limiting assembly is installed on the support plate 6, and the lead screw 7 is perpendicular to the upper surface of the support plate 6. Limiting blocks 8 are fixedly installed on both the front and rear sides of the lifting slider 10. A connecting rod 11 is hinged to the opposing surfaces of the two limiting blocks 8. The support plate 6 also has two sliding limiting rods 12 with axes parallel to the front and rear directions. Two horizontal sliders 13 are provided, each sliding with one of the two sliding limiting rods 12. The top of each horizontal slider 13 is fixedly connected to a limiting clamp 2, and the other ends of the two connecting rods 11 are hinged to a horizontal slider 13. The limiting assembly is installed entirely on the support plate 6 below the flip panel 1, as shown. Figure 5 As shown, motor 9 drives lead screw 7 to rotate, causing lifting slider 10 to move up and down. Through the geometric transmission of linkage 11, and under the limitation of sliding limit rod 12, the vertical motion is converted into the synchronous translation of horizontal slider 13. The two horizontal sliders 13 move smoothly under the guidance of sliding limit rod 12, achieving symmetrical opening and closing of limit clamping plates 2, thus providing adjustable and symmetrical limitation for the packaging box. When lead screw 7 moves up and down, the limit clamping plates 2 on both sides move at the same speed but in opposite directions, ensuring uniform force on the packaging box during limitation, avoiding box tilting or rolling direction deviation caused by unilateral clamping, and improving test accuracy. Figure 3 As shown, the end of the flipping cylinder 3 is fixed on the support plate 6, and the flipping cylinder 3 and the support plate 6 form a certain angle. The end of the flipping cylinder 3 is fixed on the support plate 6, and forms a certain angle with the support plate 6, so that when the cylinder output end pushes the packaging box, it can act on the bottom or side edge of the packaging box in an inclined direction, thereby forming a composite thrust with both horizontal and vertical components, and realizing a more natural flipping operation of the packaging box.

[0028] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention features a U-shaped plate 14 covering the motor 9. The U-shaped plate 14 has a through hole for the lead screw 7 to pass through. A guide rod 15 is vertically fixed to the upper surface of the U-shaped plate 14, parallel to the lead screw 7 and slidably engaged with the lifting slider 10. This vertically fixed guide rod 15, parallel to the lead screw 7 and slidably engaged with the lifting slider 10, provides additional guiding constraint during the up-and-down movement of the lifting slider 10 driven by the lead screw 7. This prevents the lifting slider 10 from tilting or rotating due to force deviation during its up-and-down movement, resulting in a more stable motion trajectory and avoiding jamming. By forming a cover structure with the U-shaped plate 14 above the motor 9, dust, debris, or packaging waste can be effectively prevented from entering the transmission area of ​​the motor 9 and the lead screw 7, avoiding transmission obstruction or motor 9 malfunction due to debris accumulation, thereby improving the reliability and service life of the equipment.

[0029] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention is as follows: a limiting frame 16 is provided on both the front and rear sides of the U-shaped plate 14, and each limiting frame 16 is vertically provided with at least one sliding groove 17. The two limiting blocks 8 are respectively slidably engaged with a limiting frame 16 in the vertical direction. This structure can accurately guide the up and down movement of the limiting blocks 8, preventing them from shaking or deviating during the transmission of the lead screw 7, thereby maintaining the vertical stability of the movement of the limiting blocks 8.

[0030] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention features supports 18 at both ends of the sliding limit rod 12. Both sliding limit rods 12 are connected to the support plate 6 via supports 18. The supports 18 provide reliable support and fixation for the limit rods, dispersing the dynamic load transmitted by the horizontal slider 13 and reducing vibration and fatigue stress of the limit rods during repeated opening and closing actions. To further ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention features two connecting rods 20 fixed on each limit clamp plate 2. The horizontal sliders 13 are fixedly connected to the corresponding limit clamp plates 2 via connecting rods 20. The flip panel 1 has through slots 19 for the connecting rods 20 to slide back and forth. The horizontal sliders 13 are connected to the limit clamp plates 2 via connecting rods 11. When the motor 9 drives the lead screw 7 to move the lifting slider 10, the opening and closing of the limit clamp plates 2 is achieved through the connecting rod 11 mechanism.
