Description
Technical Field
[0001] The invention relates to the technical field of fragile goods packaging, in particular to a tensile testing device for a fragile goods packaging box. Background Art
[0002] The fragile goods in this technology refer to wine bottles or wine barrels for storing wine, and the capacity of the wine bottles or wine barrels ranges from tens of kilograms to dozens of kilograms, or even up to hundreds of kilograms. The above-mentioned fragile goods containers are different from traditional 1000ml, 500ml or other small-capacity wine bottles. Traditional wine bottle packaging boxes are made of materials such as kraft paper, corrugated cardboard, or gray board paper, and their load-bearing capacity is generally from several kilograms to more than ten kilograms. It can be seen that traditional packaging boxes (boxes) can no longer meet the packaging and transportation of wine bottles or wine barrels weighing tens of kilograms to hundreds of kilograms. Therefore, improvements are made to existing packaging boxes, such as Figure 1 As shown, a wooden packing box is used, which includes a wooden base 100 and a wooden top cover 200. For the aesthetics of the decoration, the wooden base 100 and the wooden top cover 200 are connected by a box body 300 made of transparent acrylic material, so that the wine bottle or wine jar can be viewed through the box body 300, which is also convenient for observation during transportation and handling. However, the materials between the wooden base 100 and the box body 300, and the wooden top cover 200 and the box body 300 are different, and they are obtained by separate processing. During assembly, bolts or screws are used for connection. Due to the large weight of the wine bottle or wine jar (containing wine), when the packing box (containing wine bottles or wine jars) is transported and hoisted, a higher tensile resistance requirement is put forward for the packing box, that is, the wooden top cover 200 must not fall as a whole when hoisting and grabbing, and the overall tensile resistance of the packing box must be greater than the weight of the wine bottle or wine jar, the wine and the packing box as a whole, so as to ensure that the packing box, the wine bottle or wine jar are intact. However, there is no packaging box tensile test equipment in the prior art, and it is impossible to perform tensile tests.
[0003] When the tensile strength of the packaging box cannot be determined, the packaging boxes (containing wine bottles or wine barrels) in the prior art are mostly transported by forklifts, and they must be supported by wooden pallets. However, the packaging boxes (containing wine bottles or wine barrels) are prone to shaking on the wooden pallets. Therefore, it is necessary to perform complex binding and fixing of the packaging boxes and wooden pallets, which increases the workload. In addition, when the wine bottles or wine barrels are loaded with wine, the existing processes and production processes are difficult to meet the requirements of placing the packaging boxes on the wooden pallets in advance and then loading the wine, which does not conform to the production process. Therefore, in the prior art, the transportation of packaging boxes inevitably requires the lifting of the packaging boxes. Similarly, after the wooden pallet and packaging boxes are transported to the desired location, the packaging boxes (containing wine bottles or wine barrels) need to be lowered from the wooden pallet, which also requires the lifting of the packaging boxes.
[0004] Therefore, there is an urgent need to propose a tensile testing device for fragile packaging boxes with a simple structure, convenient use, accurate and reliable testing, so as to detect the tensile strength of the packaging boxes. Summary of the invention

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0038] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.
[0039] like Figures 2 to 8 As shown, this embodiment provides a tensile test device for a fragile packaging box, which performs a tensile test on the packaging box to ensure that the packaging box can withstand a lifting tension of tens to hundreds of kilograms during lifting, thereby effectively avoiding the problem of unreliable connection between the wooden base 100 and the box body 300, and between the box body 300 and the wooden top cover 200.
[0040] Specifically, the tensile test device for fragile packaging box includes a lower base 1, a column 2, an upper support seat 3, a lower buckle 4, a screw support nut 5, an adjusting screw 6, a hand wheel 7, a tensile gauge upper support seat 8, a rolling bearing 9, a connecting nut 10, a tensile gauge 11, a tensile gauge lower support seat 12 and a hook assembly 13. Among them, the column 2 is set on the four corners of the lower base 1, and the upper support seat 3 is fixed on the top of the column 2 to provide overall support. It should be noted that the tensile gauge 11 of this embodiment is a mature product, and its internal structure will not be described in detail here.
[0041] Among them, a plurality of lower buckles 4 are arranged on the lower base 1, which are opposite to the hook assembly 13, and are used to clamp and fix the lower part of the packaging box. Here, the lower buckle 4 is in a Z shape, and at least two strip grooves 41 are arranged at the rear end of the lower buckle 4, and the strip grooves 41 are connected to the lower base 1 by screws. In addition, the two strip grooves 41 can also prevent the lower buckle 4 from swinging, thereby ensuring the reliability of the connection of the lower end of the packaging box.
[0042] In addition, two screw support nuts 5 are provided and are respectively welded and fixed on the upper and lower parts of the upper support seat 3 to provide rotation support for the adjusting screw 6. The adjusting screw 6 and the screw support nut 5 are threadedly connected, and a hand wheel 7 is provided on the upper part of the adjusting screw 6 to facilitate the rotation operation.
[0043] In this embodiment, in order to provide rotation support and prevent the hook assembly 13 from rotating with the adjusting screw 6, the rolling bearing 9 and the connecting nut 10 are sleeved on the lower part of the adjusting screw 6, and a first through hole 81 is opened on the tensile gauge upper support seat 8, and the rolling bearing 9 is placed on the top of the inner wall of the tensile gauge upper support seat 8 to provide rotation support. In addition, the diameter of the first through hole 81 is larger than the diameter of the adjusting screw 6, and the diameter of the first through hole 81 is smaller than the diameter of the rolling bearing 9, so that the adjusting screw 6 can reliably rotate in the first through hole 81.
[0044] In addition, a connecting ball 1101 is respectively provided at the upper and lower parts of the dynamometer 11. The upper support seat 8 of the dynamometer is in a C shape, and a spherical notch 82 is provided at the inner lower part of the upper support seat 8 of the dynamometer, and the connecting ball 1101 is rotatably clamped in the spherical notch 82. At the same time, a spherical notch 121 and a second through hole 122 are provided in the lower support seat 12 of the dynamometer, and a first latch hole 123 is provided in the lateral direction of the lower support seat 12 of the dynamometer, and the first latch hole 123 and the second latch hole 137 are connected by a latch. In the lower support seat 12 of the dynamometer, the connecting ball 1101 at the lower part of the dynamometer 11 is placed in the spherical notch 121. The connecting ball 1101 at the upper part of the dynamometer 11 can rotate in the spherical notch 82, and the connecting ball 1101 at the lower part of the dynamometer 11 can also rotate in the spherical notch 121. In this way, it can be ensured that the dynamometer 11 and the hook assembly 13 are always arranged vertically during the test, thereby improving the accuracy and reliability of the test.
[0045] In this embodiment, the hook assembly 13 includes an upper ring platform 131 with a hole in the middle, a lower ring platform 132 arranged at the lower part of the upper ring platform 131 and arranged coaxially with the upper ring platform 131, a slide bar 133 whose lower end is fixed to the upper center of the lower ring platform 132 and whose upper part passes through the upper ring platform 131, a plurality of connecting ears 134 arranged in a circular array on the edges of the upper ring platform 131, a hook 136 whose upper end is pinned to the edges of the lower ring platform 132 and whose lower end is buckled on the wooden top cover 200, a first crank arm 135 connected to the middle of the connecting ear 134 and the hook 136 by a pin, and a second pin hole 137 opened at the top of the slide bar 133. Here, at least three hooks 136 are provided to ensure the reliability of grabbing.
[0046] The following briefly describes the use process of this embodiment:
[0047] First, use the lower buckle 4 to fix the packaging box to be tested on the lower base 1; then, turn the hand wheel 7 to move the upper support seat 8 of the dynamometer, the dynamometer 11, the lower support seat 12 of the dynamometer and the hook assembly 13 upward until the hook assembly 13 is hung on the wooden top cover 200. In the process of the hook assembly 13 being hung on the wooden top cover 200, the slide bar 133 moves upward, and driven by the lower ring platform 132 and the first crank arm 135, the hook 136 shrinks inward and is tightly buckled on the wooden top cover 200. Continue to turn the hand wheel 7 to read the tension value on the dynamometer 11 until it reaches the preset test tension value, and maintain it for 5 minutes. Among them, the preset test tension value is greater than 1.5 times or more of the total weight of the packaging box, wine bottle or wine jar, and wine.
[0048] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any changes that adopt the design principles of the present invention and are made through non-creative labor on this basis should fall within the protection scope of the present invention.
