Packaging boxes, as equipment for packaging products, can protect the products inside and play an important role in my country's transportation industry.

[0003] There is a packaging box in the prior art, which includes a bottom frame, the bottom frame is used to place stacked goods to be packaged, and side paperboards are arranged at the four corners of the bottom frame. The side paperboards are L-shaped, and the inner wall of the bottom end of the side paperboards is attached to the corresponding corners of the bottom frame and is arranged vertically. A top paperboard is also arranged above the bottom frame, and the top paperboard is against the top of the packaged goods, and the top of each side paperboard is against the bottom of the top paperboard. The four side paperboards are fixed by wrapping with tape, and the top paperboard, the bottom frame and the side paperboards are also fixed by wrapping with tape, and are packed with tape. When in use, the relevant personnel first place the goods to be packaged on the bottom frame, and then each side paperboard is set at the four corners of the bottom frame, and then the top paperboard is placed on the goods. After the placement is completed, the top paperboard, the side paperboard and the bottom frame are fixed with tape, and the tape is wrapped with tape to complete the packaging.

[0004] With regard to the above-mentioned related technologies, since in the prior art only the bottom of the side guard paperboard is in contact with the edge of the bottom frame, only the bottom of the side guard paperboard is supported. This makes it easy for the side guard paperboard to tilt significantly when it collides with other objects and is impacted during transportation, which can easily cause the packaging box to deform, thereby reducing the protection effect of the goods in the packaging box, so there is room for improvement. Summary of the invention

[0005] In order to reduce the probability of a side paperboard tilting significantly when it is hit, the present application provides a deformation-resistant packaging box and a performance detection device after the test.

[0006] In a first aspect, the present application provides an anti-deformation packaging box, which adopts the following technical solution: A deformation-resistant packaging box comprises a bottom plate frame and a top plate frame, wherein a plurality of side paperboards are arranged on the bottom plate frame, and a plurality of placement boards are also arranged on the bottom plate frame, wherein the placement boards are distributed in a vertical direction, each of the placement boards is used for placing goods, and each of the placement boards is placed on the goods located below the placement board, and the inner side wall of each of the side paperboards is close to the side end of the placement board.

[0019] By adopting the above technical solution, the lifting component and the clamping component are set up so that when the clamping component clamps the packaging box, the relevant personnel can drive the lifting frame to move upward through the lifting member, thereby lifting the packaging box, which effectively facilitates the relevant personnel to lift the packaging box.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] Embodiment 1: Embodiment 1 of the present application discloses a packaging box that prevents deformation. Figure 1 The anti-deformation packaging box includes a bottom plate frame 1 and a top plate frame 2. A plurality of side paperboards 3 are arranged on the bottom plate frame 1. A plurality of placement boards 4 are also arranged on the bottom plate frame 1. The placement boards 4 are distributed in the vertical direction. Each placement board 4 is used to place goods, and each placement board 4 is placed on the goods located below itself. The inner side wall of each side paperboard 3 is close to the side end of the placement board 4.

[0038] Reference Figure 1In the embodiment of the present application, the material of the bottom plate frame 1 is set to wood, and there is a gap in the middle position of the bottom plate frame 1 along the height direction to reduce the use of wood and increase economic benefits. In the embodiment of the present application, the placement board 4 is set to corrugated cardboard to increase the flat compression strength and buffering effect of the placement board 4, thereby better protecting the goods, while reducing the probability of large deformation of the placement board 4 during use, and reducing the probability of subsequent loosening of the strapping belt.

[0039] Reference Figure 1 Since the length and width of the placement plate 4 are relatively close, in order to improve the efficiency of on-site packaging and taking into account the requirements of fool-proofing, two special-shaped grooves 41 are penetrated on the opposite sides of the top wall of the placement plate 4, so that the opposite sides of the placement plate 4 are designed to be special-shaped while taking into account the shape of the Tray, which makes it convenient for relevant personnel to align the products between them on site and improve packaging efficiency.

[0040] Reference Figure 1 In the embodiment of the present application, the number of the placement plates 4 is set to five, and each placement plate 4 and the top wall of the bottom frame 1 are set to be rectangular, and the top area of ​​the placement plate 4 is smaller than the top area of ​​the bottom frame 1. The edge of each placement plate 4 is located within the positive projection range of the top wall of the bottom frame 1, and the length of the edge of the top wall of each placement plate 4 is smaller than the length of the edge of the top wall of the bottom frame 1. In the embodiment of the present application, the length of the edge of the top wall of the placement plate 4 is 5mm smaller than the length of the edge of the top wall of the bottom frame 1, so that the side guard paperboard 3 can be against the edge of the placement plate 4 when it is tilted or deformed, thereby preventing the side guard paperboard 3 from continuing to tilt or deform, and ensuring the overall stability of the packaging box.

[0041] Reference Figure 1 , except for the topmost placement board 4, a group of goods are placed on each of the other placement boards 4, and except for the bottommost placement board 4, the bottom ends of the other placement boards 4 are placed on the goods below them, thereby forming a stack. In the embodiment of the present application, a limit mark is set on the bottom plate frame 1 for reference by relevant personnel when stacking goods, thereby ensuring that the placement position of the goods is accurate.

[0042] Reference Figure 1 , the top board frame 2 is placed on the placement board 4 at the top, and the top board frame 2 is made of wood. Each side paperboard 3 is L-shaped, the bottom end of each side paperboard 3 is in contact with the ground, and the bottom end of each side paperboard 3 is sleeved on the bottom board frame 1, so that the inner side wall of the side paperboard 3 is in contact with the side wall of the bottom board frame 1. The top end of each side paperboard 3 is sleeved on the top board frame 2, so that the inner side wall of the side paperboard 3 is in contact with the side end of the top board frame 2, and the top end of each side paperboard 3 is flush with the top wall of the top board frame 2.

[0043] Reference Figure 1The side guards 3, the side guards 3 and the bottom frame 1, and the side guards 3 and the top frame 2 are all fixedly connected by adhesive tape (not shown in the figure). After the adhesive tape is fixedly connected, a packing tape (not shown in the figure) is also provided to fix the top frame 2 and the bottom frame 1 to increase the stability of the packaging box.

[0044] The implementation principle of the anti-deformation packaging box in Example 1 of the present application is as follows: when the packaging box is impacted by contact with other objects, causing the side guard paperboard 3 to be slightly displaced, the inner wall of the side guard paperboard 3 can be against the side end of the placement plate 4, thereby supporting the side guard paperboard 3 and preventing the side guard paperboard 3 from further displacement, thereby reducing the probability of the side guard paperboard 3 being significantly tilted, effectively reducing the probability of the packaging box being significantly tilted or damaged, and thus ensuring the protective effect of the packaging box of the present application on the goods.

[0045] On the other hand, since the side guard paper 3 is not subjected to force in the prior art, and the side guard paper 3 is subjected to force in Example 1 of the present application, it is necessary to evaluate whether the strength of the side guard paper 3 meets the standard to ensure the strength of the side guard paper 3. Therefore, Example 1 of the present application also discloses a method for evaluating the strength of the side guard paper 3, which is as follows: Calculate the evaluation height: Take 80% of the height of the whole pallet after the product is packed as the evaluation height; Calculate the compressive strength of the side guard paperboard 3: the compressive strength of the side guard paperboard 3 = -0.779 × evaluation height + 35.118 × width + 252.288 × thickness - 949.49; Calculate the compressive strength of a single side guard paperboard 3: compressive strength of a single side guard paperboard 3 = compressive strength of side guard paperboard 3 ÷ 9.8; Evaluate strength: subtract the compressive strength of the four side guard paperboards from the maximum pressure of 4 layers stacked (i.e. the compressive strength of the 4 side guard paperboards - the maximum pressure of 4 layers stacked), calculate the difference, if the difference is greater than zero, the strength requirement is met.

[0046] As a preferred embodiment, the strength verification of the side guard paperboard 3 with a width of 95 mm, a thickness of 8 mm and an evaluation height of 760 mm is used as a standard, then: The compressive strength of the side guard paperboard 3 = -0.779 × 760 + 35.118 × 95 + 252.288 × 8 - 949.49 = 3812.984 N, take the two decimal places to get 3812.98 N; Therefore, the compressive strength of a single side guard paperboard 3 = 3812.98N ÷ 9.8 = 389.08kg 4 side guard paperboards 3 compressive strength = 4 × 389.08 = 1556.32 kg Maximum pressure of stacking 4 layers = 270kg × (4-1) = 810kg Therefore, the compressive strength of 4 side guard paperboards 3 - the maximum pressure of stacking 4 layers > 0.

[0047] It can be seen that when the longitudinal compressive strength of the side guard paperboard 3 is calculated and verified, the strength of the side guard paperboard 3 in the present application meets the requirements of the 4-layer storage.

[0048] In addition, since the material of the placement plate 44 is changed in Example 1 of the present application, it is necessary to verify the strength of the corrugated cardboard. Therefore, Example 1 of the present application also discloses a method for verifying the strength of the corrugated cardboard, which is as follows: Measure the flat compression strength; measure the flat compression strength of corrugated cardboard; Calculate the contact area between the corrugated board and the product: contact area = number of single-layer products × π × radius of a single product × radius of a single product; Evaluate the strength of corrugated cardboard: subtract the flat compression strength of the corrugated cardboard from the stress strength of the bottom layer of the product. When the result is less than 0, the flat compression strength meets the requirements.

[0049] As a preferred embodiment, a corrugated cardboard with a measured flat compressive strength of 0.82kg / cm2 and a single-layer product stacking setting with a product diameter of 26.8cm and 13 single-layer products is used as an example: The area of ​​corrugated cardboard in contact with the product = 13 × π × (26.8 ÷ 2) × (26.8 ÷ 2) = 7333.36 cm2 The flat compressive strength of corrugated cardboard = 7333.36cm2×0.82kg / cm2=6913.36 kg The bearing strength of the bottom layer of the product = 270kg × 4 = 1080 kg < 6913.36 kg (flat compression strength of corrugated cardboard) It can be seen that the flat compression strength of the corrugated cardboard meets the requirements.

[0050] On the other hand, after the strength of the side guard paperboard 3 and the corrugated paperboard meets the requirements, the packaging box of the present application needs to be tested through a transport packaging test. After the test is completed, in order to better reflect the radial deformation of the packaging box before and after the test in Example 1 of the present application, Example 1 of the present application also discloses a verification method that is convenient for reflecting the deformation after the test, and the method is as follows: Mark the measurement location: Use a black marker pen to mark the connection between the paperboard 3 and the top frame 2 on each side; Hanging the plumb bob: prepare the plumb bob, straighten the plumb bob rope, and make the marks on the two opposite sides touch the bottom end of the rope, and make the plumb bob hang downward from one side of the side guard plate 3; Measure radial deformation: measure the vertical distance between the rope body and the side of the bottom plate frame 1, and record the data; Measure the lateral deformation: measure the vertical distance between the rope body and the three edges of the corresponding side guard paperboard, and record the data; Repeat the measurement: hang a plumb bob at each relative mark, measure the radial deformation and the lateral deformation, and record the data in sequence.

[0051] Calculate the tilt angle: Calculate the tilt angles of the four corners at the top of the box based on the original parameters of the box and the measured data.

[0052] Here is a schematic diagram of the radial deformation detection positions in the top view of the packaging box (i.e. Figure 2 ), where 4-5-A is taken as an example, showing the A detection point of the side guard paperboard 3 between surface 4 and surface 5.

[0053] Now we give a schematic diagram of the comparison of the deformation of the scheme (i.e. Figure 3 ), which includes a schematic diagram of deformation after the prior art test and a schematic diagram of deformation measurement after the test of the packaging box of the present application, so as to conveniently and intuitively reflect the effect of the packaging box of the present application after the test, wherein the dotted arrow indicates the original position, and the realized arrow indicates the tilt direction after the test.

[0054] It can be seen that in the above diagram Figure 2 and Figure 3 In the new scheme, angle 1-2-5 is not offset, angle 1-2-6 and angle 1-4-6 are tilted toward edge 4-6, and angle 1-4-5 is tilted toward edge 2-6, resulting in a phenomenon of mutual cancellation.

One end of each active frame 761 is rotatably connected to the lifting frame 721 through a pin shaft, the top end of each active frame 761 is rotatably connected to the lifting frame 721 through a pin shaft, and the bottom end of each active frame 761 is rotatably connected to one end of the rotating frame 762 through a pin shaft.

[0063] Reference Figure 4 , Figure 5 and Figure 6 Each rotating frame 762 is rotatably connected to the transport frame 71 through a pin in the middle of its length direction, and one end of each rotating frame 762 away from the active frame 761 is rotatably connected to one end of the extension frame 752 through a pin. In the initial state, that is, when the clamping assembly 74 does not clamp the packaging box and the lifting frame 721 is at the bottom of its own sliding path, the end of the extension frame 752 away from the rotating frame 762 is obliquely extended downward in the direction away from the conveyor belt 6.

[0064] Reference Figure 5 and Figure 7 Each main frame 751 is sleeved on one end of the corresponding extension frame 752 extending downward, and is slidably connected to the corresponding extension frame 752, and each extension frame 752 passes through the corresponding main frame 751. Each main frame 751 is rotatably connected to the transport frame 71 through a pin. A supporting bottom portion 7521 is further extended from one end of each extension frame 752 away from the rotating frame 762, and the supporting bottom portion 7521 is bent relative to the main body of the extension frame 752 to contact the bottom end of the packaging box.

[0065] Reference Figure 4 , Figure 5 and Figure 7In the initial state, that is, when the clamping assembly 74 does not clamp the packaging box and the lifting frame 721 is at the bottom of its own displacement path, the extension frame 752 is located on the side of the packaging box close to the conveyor belt 6, and is not located on the displacement path of the packaging box when it is lifted by the lifting frame 721. When it is necessary to clamp the packaging box, the two clamping frames 741 are driven by the driving member 742 to approach each other to clamp the packaging box, and at the same time, the lifting portion 7411 on the clamping frame 741 is inserted into the vacant part of the bottom plate frame 1 on the packaging box.

[0066] Reference Figure 5 and Figure 7 Then, the lifting frame 721 slides upward under the drive of the lifting member 722 to lift the packaging box. In this process, the lifting frame 721 drives the active frame 761 to move, so that the active frame 761 drives the rotating frame 762 to rotate, and then the bottom end of the rotating frame 762 slides toward the direction close to the main frame 751, so that the rotating frame 762 drives the extension frame 752 to slide relative to the main frame 751, so as to approach the packaging box.

[0067] Reference Figure 5 and Figure 7 At the same time, the extension frame 752 rotates under the drive of the main frame 751, so that the supporting bottom 7521 on the extension frame 752 is offset upward, thereby gradually approaching the bottom wall of the packaging box. When the packaging box is lifted to the specified position, the supporting bottom 7521 on the extension frame 752 contacts the bottom end of the packaging box, thereby supporting the bottom end of the packaging box.

[0068] Reference Figure 4 , Figure 5 and Figure 7 After that, the rotating member 73 drives the transport frame 71 to rotate 180 degrees, so that the packaging box is moved to the top of the conveyor belt 6. Then, the lifting member 722 drives the lifting frame 721 to move downward. During this process, the extension frame 752 is driven by the linkage assembly 76 to rotate downward and move away from the packaging box, thereby leaving the displacement path of the packaging box. When the bottom end of the packaging box is close to the conveyor belt 6, the two clamping frames 741 gradually move away and contact the packaging box, so that the packaging box falls onto the conveyor belt 6 frame to complete the transportation.

[0069] Reference Figure 4 and Figure 8The detection mechanism 8 includes a detection member 81, a control member 82 and a display member 83. In the embodiment of the present application, the detection member 81 is configured as a plurality of high-definition cameras, the control member 82 is a control computer, and the display member 83 is a display screen. Each high-definition camera and the display screen are electrically connected to the control computer. A plurality of high-definition cameras are fixedly mounted on the four inner side walls and the inner top wall of the device body 5, and the camera ends are all facing the packaging boxes on the conveyor belt 6. Each high-definition camera is used to photograph the packaging boxes on the conveyor belt 6, so as to obtain photos of the packaging boxes in multiple directions after the ISTA test.

[0070] Reference Figure 4 and Figure 8 Each high-definition camera is used to feed back the photo information after taking the photo to the control unit 82, and the control unit 82 is used to receive the photo information transmitted by each high-definition camera. The control unit 82 also pre-stores photos of the packaging box in various directions (i.e., each high-definition camera) when it has not been tested by ISTA (i.e., intact, without deformation and damage), and pre-stores the size data of the packaging box when it has not been tested by ISTA (e.g., length, width, height, and data when each side wall and top wall are flat).

[0071] Reference Figure 4 and Figure 8 , the control component 82 is used to compare the photo information transmitted by the high-definition camera with the pre-stored photo information, and identify and calculate the offset angle of the transmitted photo information. At the same time, the control component 82 also calculates the size data of the actual packaging box after the ISTA test based on the compared ratio and the pre-selected size data of the packaging box before the ISTA test, and obtains the deformation amount or offset angle of each size of the packaging box after the ISTA test by making a difference. After calculating the deformation amount or offset angle, the control component 82 controls the display component 83 to display the relevant data together with the original preset data, so that relevant personnel can know it.

[0072] The implementation principle of the performance detection device after the packaging box test in Example 2 of the present application is as follows: when it is necessary to detect the deformation of the packaging box after the ISTA test, the clamping component 74 clamps the packaging box on the ground, and then the lifting component 72 lifts the packaging box. During this process, the bottom frame 75 rotates to support the bottom end of the packaging box. Next, the transport frame 71 drives the packaging box to rotate 180 degrees, so that the packaging box is located directly above the conveyor belt 6. Thereafter, the lifting component 72 drives the packaging box to descend, and after the packaging box is close to the conveyor belt 6, the clamping component 74 releases the clamping of the packaging box. Thereafter, the packaging box is transported by the conveyor belt 6, and is moved to the designated detection position, and is detected by the detection mechanism 8.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
