Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a multi-directional pressure bearing capacity quality inspection device. Background Art

[0002] Carton pressure testing refers to the evaluation of the performance of cartons when subjected to external pressure or weight to ensure that they can effectively protect the contents during transportation and storage.

[0003] In conjunction with the publication (announcement) number CN117268935A, the publication (announcement) date is 2023-12-22, and a multi-directional pressure-bearing capacity quality inspection device for corrugated cardboard boxes is disclosed, including a detection platform and a box to be inspected. Four rectangular power boards are connected to the top of the detection platform. The power boards are connected to two electromagnetic boards through wires. The bottom ends of the two electromagnetic boards are connected to slide rails. The inner side walls of the slide rails are connected to magnetic sliders. The tops of the magnetic sliders are connected to two fixed frames through two connecting plates. The present invention can use the drive gear to drive multiple driven gears on the outside to rotate, change the angle of the expansion arc plate, and adjust different pressure-bearing points of the box for detection. At the same time, the setting of the steering plate and the multi-segment elastic arc plate can use the steering plate to adjust the direction of the multi-segment elastic arc plate according to the detection needs, so as to facilitate the detection of the inner and outer corners of the box.

[0004] However, in the existing technologies including the above-mentioned patents, only the pressure bearing capacity of the corners of the cartons is tested. During the stacking and transportation process, the sides of the cartons will be subjected to friction generated by contact with the outside world. This friction has a pulling effect on the sides of the carton, causing the corners to be subjected to greater tensile stress, which will also lead to problems such as carton deformation.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, a multi-directional pressure bearing capacity quality inspection device includes a workbench 2 for placing cartons and a press 1 arranged to move along the vertical direction, including:

[0029] The corner pressure measuring mechanism 3 comprises:

[0030] Rotate the rotating rod 34 provided on the workbench 2;

[0031] The pressure plates 35 are relatively slidably disposed on the workbench 2 and are used to press the sides of the carton, and are driven to move closer to or away from each other along the sides;

[0032] The rotating rod 34 and the pressure plate 35 are slidably matched.

[0033] Specifically, the press 1 can be a hydraulic cylinder or a crank press, or other pressure mechanisms known to those skilled in the art. A chute 351 is provided on the pressure plate 35, and a cylinder provided at the end of the rotating rod 34 slides in the chute 351.

[0034] Furthermore, the carton is placed on the workbench 2, and the pressure plate 35 is pressed against the side of the carton, as shown in FIG. Figure 3 As shown, the carton is initially fixed. Subsequently, vertical pressure is applied to the carton by starting the press 1, and the rotating rod 34 can be driven to rotate toward the corner of the carton by setting a motor or using a sprocket drive. The cylindrical push chute 351 set at the end of the rotating rod 34 drives the two symmetrical pressure plates 35 located on the same side away from each other. At this time, the pressure plates 35 slide from the middle of the side toward the corner, and the friction force of the pressure plates 35 on the side of the carton has a pulling effect. The wrinkles on the carton surface can be observed by the naked eye, thereby detecting the tensile strength of the carton side.

[0035] In the above technology, the cylindrical push groove 351 set at the end of the rotating rod 34 drives the two symmetrical pressure plates 35 located on the same side to move away from each other, and the pressure plates 35 slide from the middle of the side to the corner. The friction force of the pressure plates 35 on the side of the carton has a pulling effect, thereby detecting the tensile performance of the side of the carton and detecting the deformation of the carton under concentrated tensile stress.

[0036] As an embodiment further provided by the present invention, there is a triggering station in the movable stroke of the press 1 for triggering the rotation of the rotating rod 34 .

[0037] Specifically, a pressure sensing switch can be set on the workbench 2, or an infrared sensing switch can be set at the height of the triggering station. When the press 1 reaches the triggering station, the pressure sensing switch or the infrared sensing switch is triggered, thereby starting the motor or sprocket to drive the rotating rod 34 to deflect toward the corner of the carton, so that the press 1 starts the corner pressure measuring mechanism 3 while pressing down, and can test the surface tensile properties of the carton while fixing the carton.

[0038] As another embodiment further provided by the present invention, the present invention further includes a driving gear 32 that is rotatably disposed on the workbench 2;

[0039] A driven gear 33 is fixedly mounted on the end of a rotating rod 34 and meshes with a driving gear 32 for transmission;

[0040] The pressure rod 31 is sleeved in the driving gear 32 and slidably engaged with the driving gear 32 , and its default height is consistent with the height of the triggering station.

[0041] Specifically, it also includes a second spring 312 for keeping the pressure rod 31 at the default height. When the press 1 reaches the triggering position, it contacts the pressure rod 31 at the default height and pushes the pressure rod 31 downward, the second spring 312 contracts and accumulates force, and the pressure rod 31 is provided with a guide groove 311 that is slidably connected to the drive gear 32. The pressure rod 31 moves downward, and the drive gear 32 is driven to rotate through the guide groove 311, and the drive gear 32 drives the driven gear 33 to rotate, so that the driven gear 33 drives the rotating rod 34 to deflect toward the corner of the carton; and when the press 1 moves upward, the stored force of the second spring 312 is released, pushing the pressure rod 31 upward, thereby driving the drive gear 32 to rotate, and the drive gear 32 drives the rotating rod 34 to deflect and away from the corner of the carton through the driven gear 33. At this time, the two symmetrical pressure plates 35 on the same side approach each other and return to their initial state.

[0042] As another embodiment further provided by the present invention, the pressure plate 35 includes an anti-slip pad 352 close to the side of the paper box, and a first spring 353 is provided on the anti-slip pad 352 for maintaining a predetermined distance from the pressure plate 35.

[0043] Specifically, the first spring 353 makes the distance between the anti-slip pad 352 and the pressure plate 35 adjustable. During the placement of the carton, the side wall of the carton pushes the anti-slip pad 352 aside before placement. This can be adaptively adjusted according to the size of the carton, and has a wide range of uses.

[0044] As another embodiment further provided by the present invention, the anti-skid pad 352 and the pressure plate 35 are connected via a transmission rod, and the transmission rod is tilted due to the speed difference between the anti-skid pad 352 and the pressure plate 35.

[0045] Specifically, the anti-slip pad 352 is against the side of the carton. During the sliding process of the pressure plate 35 along the side of the carton, since the anti-slip pad 352 is made of rubber material with greater friction, the direction of the friction force of the side on the anti-slip pad 352 is opposite to the moving direction of the pressure plate 35. A speed difference is generated between the anti-slip pad 352 and the pressure plate 35, causing the transmission rod to tilt, and the distance between the anti-slip pad 352 and the pressure plate 35 gradually decreases, and the first spring 353 is gradually compressed. At this time, the elastic force of the first spring 353 is applied to the side wall of the carton through the anti-slip pad 352, and the elastic force gradually increases with the compression of the first spring 353, exerting pressure on the corners of the carton, thereby testing the pressure bearing capacity.

[0046] Working principle: Place the carton on the workbench 2 so that the side walls of the carton squeeze the anti-slip pad 352 and then place it. It can be adaptively adjusted according to the size of the carton. Start the press 1 to apply vertical pressure to the carton. When the press 1 reaches the trigger position, it contacts the pressure rod 31 at the default height and pushes the pressure rod 31 downward. The second spring 312 contracts to store force. The pressure rod 31 is provided with a guide groove 311 that is slidably connected to the drive gear 32. The pressure rod 31 moves downward and drives the drive gear 32 to rotate through the guide groove 311. The drive gear 32 drives the driven gear 33 to rotate, so that the driven gear 33 drives the rotating rod 34 to deflect toward the corner of the carton. The cylindrical push groove 351 set at the end of the rotating rod 34 drives the two symmetrical pressure plates 35 located on the same side to move away from each other. At this time, the pressure plate 35 slides from the middle of the side to the corner. Since the anti-slip pad 352 is made of rubber material with greater friction, the direction of the friction force of the side on the anti-slip pad 352 is opposite to the moving direction of the pressure plate 35. A speed difference is generated between the anti-slip pad 352 and the pressure plate 35, causing the transmission rod to tilt, and the distance between the anti-slip pad 352 and the pressure plate 35 gradually decreases, and the first spring 353 is gradually compressed. At this time, the elastic force of the first spring 353 is applied to the side wall of the carton through the anti-slip pad 352, and the elastic force gradually increases with the compression of the first spring 353, applying pressure to the corners of the carton, thereby testing the pressure-bearing effect, and the wrinkling condition of the carton surface can be observed by the naked eye, thereby detecting the tensile strength of the side of the carton. After the test is completed, the press 1 moves upward, the stored force of the second spring 312 is released, and the push rod 31 moves upward, thereby driving the driving gear 32 to rotate. The driving gear 32 drives the rotating rod 34 to deflect and move away from the corner of the carton through the driven gear 33. At this time, the two symmetrical pressure plates 35 on the same side approach each other and return to their initial state.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
