Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging box detection, in particular to a compression resistance quality detection equipment for packaging box production. BACKGROUND

[0002] With the rapid development of the logistics industry, long-distance transportation of goods increasingly needs safe and reliable protection. As an indispensable part of modern logistics, packaging boxes bear the important responsibility of containing and protecting products. Corrugated paperboard and corrugated paper boxes are the largest part of the packaging materials we use, and their performance directly affects the protection ability of the packaged products. Unqualified paper boxes may cause damage and deformation of the packaged products, so the compression resistance of the paper boxes is crucial. In addition, the packaging paper boxes used as outer packaging during transportation may be stacked several layers, and the braking and turning during automobile transportation will cause the packaging paper boxes inside to bear extrusion from different directions, which requires the packaging paper boxes to have certain extrusion resistance. During long-distance transportation, the packaging paper boxes bear the heavy responsibility of protecting products, so it is particularly important to test the extrusion resistance of the packaging paper boxes in multiple aspects before transportation.

[0003] The existing compression resistance detection of packaging paper boxes is through single compression value detection of the detection equipment and manual observation of the extrusion deformation of the packaging paper boxes to judge the compression resistance and damage degree, but the detection result is not accurate due to incomplete detection data and inaccurate manual judgment, so it is difficult to understand the compression damage degree of the packaging paper boxes in detail, which is not conducive to the subsequent use and stacking of the packaging paper boxes. In addition, the existing compression resistance detection equipment cannot extrude and detect the bearing strength of the side of the packaging paper box, so the detection of the packaging paper box is not comprehensive.

[0004] A packaging box extrusion testing device is disclosed in Chinese Patent CN118583650A, which includes a conveying module for intermittently conveying packaging boxes, a U-shaped frame installed at the upper middle part of the conveying module, a rectangular groove provided in the middle part of the U-shaped frame, an extrusion module installed at the upper middle part of the U-shaped frame for extruding the packaging boxes, two moving modules installed on the left and right sides of the U-shaped frame, and a testing module installed between the two moving modules for deforming detection of the side and corrugated edge of the extruded packaging box. The invention realizes the function of deforming detection of the side and corrugated edge of the packaging box. However, the invention can only detect the pressure of the packaging paper box in a horizontal state, so it cannot complete the extrusion and compression resistance detection of multiple sides of the packaging box, resulting in one-sidedness of the packaging paper box detection and limitation of the detection result.

[0035] Referring to Figure 1 , Figure 5 and Figure 8 , when the compression test of the packaging box is carried out, the packaging box is first placed in the center of the support disc 4, and then the two electric push rods 10 on the top surface of the support disc 4 are started to clamp the packaging box by the clamping plate 11, and then the compression test mechanism 2 is started to extrude the packaging box, when the packaging box is extruded to the limit, the packaging box collapses and is concave, at this time, the first telescopic cylinder 5 drives the detection mechanism 6 to move in the vertical direction of the surface of the support disc 4, so as to measure the collapse and concave degree of the packaging box.

[0036] Specifically, referring to Figure 2 , the compression test mechanism 2 includes a cross frame 21 mounted on the workbench 1, the top surface of the cross frame 21 is provided with a cylinder 22, the output end of the cylinder 22 is connected with a compression beam 23, the compression beam 23 is slidably mounted on the inner side of the cross frame 21 through a guide rod, a compression plate 24 is arranged below the compression beam 23, the compression plate 24 is connected with the compression beam 23 through a balance guide frame 25, and a pressure sensor 26 is arranged between the compression beam 23 and the compression plate 24; in use, the cylinder 22 pushes the compression beam 23 to move downward, the compression beam 23 drives the compression plate 24 to move downward under the guidance of the guide rod to extrude the packaging box, in the process of extrusion, the balance guide frame 25 plays a balance role on the compression plate 24, wherein the four spring assemblies in the balance guide frame 25 can provide an adjustable elastic force, so that the compression action is more stable and controllable, which is helpful to protect the pressure sensor 26, and the pressure sensor 26 can detect the pressure value applied on the carton in real time, and convert the pressure signal into an electric signal to transmit to the externally connected control system, when the packaging box is extruded and collapsed, the control system can obtain the maximum compression value of the packaging box, and the compression is paused.

[0037] The detection mechanism 6 includes an iris structure component 8, which includes a chassis 81 connected to one end of the telescopic rod of the first telescopic cylinder 5. A limiting ring 82 is fixedly connected to the top surface of the chassis 81. A toothed ring 83 is rotatably provided on the inner side of the limiting ring 82. Four internal toothed segments 831 are evenly spaced on the inner wall of the toothed ring 83. A positioning pin is provided on one side of each internal toothed segment 831. A first gear 84 that meshes with the internal toothed segment 831 is rotatably mounted on the positioning pin. An iris blade 85 is provided on one side of the first gear 84. A sliding groove 851 is provided on the iris blade plate 85, and a limiting pin 86 is provided in the sliding groove 851 for limiting the movement of the iris blade plate 85. A rack 852 that meshes with the first gear 84 is provided on the outer side of the iris blade plate 85. An external tooth section 832 is provided on the outer wall of the toothed ring 83. A first motor 87 is provided on one side of the external tooth section 832. The first motor 87 is mounted on the chassis 81. The output end of the first motor 87 is connected to a second gear 88 that meshes with the external tooth section 832. A top plate 89 is provided on the top surface of the limiting ring 82.

[0038] Specifically, refer to Figure 3 As shown, when conducting a compression test on a packaging box, for packaging boxes of different sizes, the packaging box is first placed in the placement space of the iris structure component 8. Then, the first motor 87 is started to drive the second gear 88 to rotate. The first motor 87 is embedded in the chassis 81, and the output end of the first motor 87 is connected to the second gear 88. The second gear 88 drives the gear ring 83 to rotate through the external gear segment 832. The rotating gear ring 83 drives the first gear 84 on one side to rotate through the four internal gear segments 831. Subsequently, the rotating first gear 84 drives the first gear 84 on one side to rotate through the rack 852. The iris leaf plate 85 moves, and when the iris leaf plate 85 moves, its slide groove is limited by the limiting pin 86 to limit the movement of the iris leaf plate 85. This allows the four iris leaf plates 85 to control the size change of the placement space at the center position when they move. As the placement space shrinks, the four iris leaf plates 85 will push the packaging boxes in the placement space to move, eventually causing the packaging boxes of different sizes to move closer to the center position of the support plate 4. Then, the two electric push rods 10 can be activated and the clamping plates can be used to clamp and position the packaging boxes.

[0039] Reference Figure 4 As shown, the detection mechanism 6 also includes a detection component installed within the iris structure assembly 8. The detection component includes an industrial camera 61 mounted on the side of the iris leaf plate 85. A mounting groove 853 is provided on the side of the iris leaf plate 85 near the center of the support plate 4. The industrial camera 61 is installed within the mounting groove 853 and is connected to an external image processing system. The industrial camera 61 can be a CCD camera or a CMOS industrial camera. Figure 4Three industrial cameras 61 are installed in the installation groove 853, and the number of industrial cameras 61 can be adjusted according to the size of the specific packaging box during specific use;

[0040] Specifically, referring to Figure 8 As shown in the figure, when the compression resistance of the packaging box in the horizontal direction is detected, the clamping of the packaging box is completed by the two electric push rods 10 and the clamping plate 11, and then the compression detection mechanism 2 is started to extrude the packaging box. During the extrusion of the packaging box, the movement of the iris leaf plate 85 can be finally driven by starting the first motor 87 to adjust the distance between the iris leaf plate 85 and the industrial camera 61 on it and the packaging box. Specifically, when the industrial camera 61 is close to the packaging box, it can more clearly capture the deformation of the side of the packaging box when it is extruded, and when the industrial camera 61 is away from the packaging box, it can capture a larger range. Moreover, the first telescopic cylinder 5 can be started to drive the iris structure assembly 8 and the industrial camera 61 to reciprocate in the vertical direction of the disc surface of the supporting disc 4. The industrial camera 61 can capture the deformation of the packaging box in real time and transmit the image to the external image processing system. Through image analysis, it can be clearly seen whether the packaging box is over-deformed or broken, and the damage degree and change of the packaging box in the compression test can be provided. In addition, when the packaging box is extruded and collapsed, the pressure control system obtains the maximum compression resistance of the packaging box, and after the compression is paused, the distance for shooting and measuring can also be adjusted by the iris structure assembly 8 to take pictures and measure the collapsed part of the damaged packaging box, and finally obtain the damage degree of the packaging box in this compression test.

[0045] Referring to Figure 9 When the packaging box is tilted by a certain angle, the lower pressing detection mechanism 2 is started to press the side of the packaging box, in the process of pressing, the detection mechanism 6 can be started to take a picture of the deformation of the packaging box in the process of pressing and transmit the image to an external image processing system, so as to judge the damage degree of the packaging box when the side of the packaging box is pressed, and thus the test of the multiple sides of the packaging box can be carried out by changing the placement surface of the packaging box;

[0046] In addition, the other rotating mechanism in the two-degree-of-freedom rotating mechanism 7 can drive the packaging box that has been rotated and tilted to rotate around the center of the through hole 3, so as to avoid the inaccuracy or error caused by the fixed position or single pressing direction in the test process, so that the test result is more stable and reliable; in particular:

[0047] When the shaft seat 72 needs to drive the support disc 4 to rotate, the second motor 92 is started to drive the first worm 91 to rotate, and the first worm 91 drives the first worm gear 78 to rotate, and then the first worm gear 78 can drive the shaft seat 72 to rotate on the mounting frame 71, so that the shaft seat 72 will drive the rotating rod 75 and the support disc 4 connected thereto to rotate, thereby driving the packaging box to rotate, to increase the accuracy and comprehensiveness of the packaging box side compression test.
