[0002] Lightweight cardboard boxes refer to environmentally friendly packaging solutions that reduce the weight of the cardboard box and the amount of raw materials used by optimizing design and material selection while ensuring the protective performance of the product. These cardboard boxes not only help reduce transportation costs and environmental burden, but also meet diverse product packaging needs. Packaging cardboard box strength testing devices are professional equipment used to assess whether these cardboard boxes can withstand common stresses in logistics processes such as stacking, vibration, and impact. These devices typically include compression testing machines, drop testing machines, and vibration testing platforms. By simulating various situations in the actual logistics environment, they ensure that lightweight cardboard boxes can still provide sufficient strength and stability to protect the contents while reducing the amount of materials used.

[0003] The problem with existing technology is that existing equipment often lacks effective clamping measures, making it difficult to securely and properly fix paper boxes of different sizes and shapes when conducting paper box strength tests. This problem not only makes the paper boxes prone to displacement or tilting during the test, resulting in uneven force and distorted test results, but also significantly increases the complexity of operation.

It solves the problem that existing equipment often lacks effective clamping measures, making it difficult to securely and properly fix cardboard boxes of different sizes and shapes during cardboard box strength testing. This problem not only makes the cardboard box prone to displacement or tilting during the testing process, resulting in uneven force and distorted test results, but also significantly increases the complexity of operation.

[0005] This utility model is implemented as follows: a lightweight packaging paper box strength testing device includes a compression testing machine body, an upper pressure plate and a lower pressure plate. The output end of the compression testing machine body is fixedly connected to the upper pressure plate, and the lower pressure plate is placed at the bottom of the upper pressure plate. The bottom of the lower pressure plate is fixedly connected to the bottom of the compression testing machine body. The lower pressure plate has a receiving groove inside, and auxiliary components are arranged inside the receiving groove.

[0006] In a preferred embodiment of this invention, the auxiliary component includes a gear, a rotating rod, and a connecting rod. The gear is placed inside the receiving groove, with its bottom rotatably connected to the bottom of the receiving groove. The rotating rod is fixedly connected to the top of the gear, and its top is rotatably connected to the top of the receiving groove. Connecting rods are placed on both the front and rear sides of the receiving groove, with the tops of both sides of the rotating rod rotatably connected to the bottom of the connecting rod. By providing this auxiliary component, the synchronous opening and closing adjustment of the limiting plate can be achieved, thereby adapting to the clamping requirements of paper boxes of different sizes and improving clamping stability and ease of operation.

[0007] As a preferred embodiment of this utility model, the top of the lower pressure plate is provided with through slots on both the front and rear sides. A slider is placed inside each through slot. The slider is slidably connected to the inside of the through slot. The top of the connecting rod at the opposite end is fixedly connected to the bottom of the slider. The top of each slider is fixedly connected with a limiting plate. The limiting plate is O-shaped.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1 to 4, the present invention provides a lightweight packaging paper box strength testing device, including a compression testing machine body 1, an upper pressure plate 2 and a lower pressure plate 3. The output end of the compression testing machine body 1 is fixedly connected to the upper pressure plate 2, and the lower pressure plate 3 is placed at the bottom of the upper pressure plate 2. The bottom of the lower pressure plate 3 is fixedly connected to the bottom of the compression testing machine body 1. The lower pressure plate 3 has a receiving groove 4 inside, and an auxiliary component 5 is provided inside the receiving groove 4.

[0023] Referring to Figure 3, the auxiliary component 5 includes a gear 501, a rotating rod 502, and a connecting rod 503. The gear 501 is placed inside the receiving groove 4. The bottom of the gear 501 is rotatably connected to the bottom of the receiving groove 4. The top of the gear 501 is fixedly connected to the rotating rod 502. The top of the rotating rod 502 is rotatably connected to the top of the receiving groove 4. Connecting rods 503 are placed on both the front and rear sides of the receiving groove 4. The tops of both the front and rear sides of the rotating rod 502 are rotatably connected to the bottom of the connecting rod 503.

[0024] By adopting the above solution, the synchronous opening and closing adjustment of the limiting plate 8 can be achieved by setting the auxiliary component 5, thereby adapting to the clamping requirements of paper boxes of different sizes and improving clamping stability and ease of operation.

[0025] Referring to Figure 2, the top of the lower pressure plate 3 has through grooves 6 on both the front and back sides. Slider 7 is placed inside the through grooves 6. The slider 7 is slidably connected to the inside of the through groove 6. The top of the connecting rod 503 at the opposite ends is fixedly connected to the bottom of the slider 7. The top of the slider 7 is fixedly connected to a limiting plate 8. The limiting plate 8 is O-shaped.

[0026] By adopting the above solution, by setting the through groove 6, a clear movement trajectory can be provided for the slider 7, ensuring that the slider 7 can only move in the predetermined direction, thus avoiding lateral deviation or tilting.

[0027] Referring to Figure 4, a rack 9 is placed on the right side of the gear 501. The bottom of the rack 9 is slidably connected to the bottom of the receiving groove 4. The gear 501 and the rack 9 are meshed together. A lead screw 10 is placed inside the receiving groove 4. The front end of the lead screw 10 is rotatably connected to the front side of the receiving groove 4. The rear end of the lead screw 10 passes through and extends out of the rear side of the lower pressure plate 3. The rack 9 is threadedly connected to the surface of the lead screw 10. A motor 11 is fixedly connected to the rear side of the lower pressure plate 3. The rear end of the lead screw 10 is fixedly connected to the output end of the motor 11.

[0028] By adopting the above scheme, automatic control of the gear 501 and connecting rod 503 mechanism is realized by setting rack 9, lead screw 10 and motor 11, so that the limit plate 8 can automatically adjust the clamping position according to the size of the paper box, which significantly improves the ease of operation and automation level of the equipment.

[0029] Referring to Figure 2, stabilizing grooves 12 are provided on both the left and right sides of the top of the lower pressure plate 3, and the left and right sides of the bottom of the limiting plate 8 are slidably connected to the inside of the stabilizing grooves 12.

[0030] By adopting the above solution, by setting the stabilizing groove 12, it can be ensured that the limiting plate 8 remains stable during movement, preventing it from shifting or tilting, thereby improving the accuracy of clamping and the stability of testing.

[0031] Referring to Figure 1, an isolation plate 13 is placed on the top of the lower pressure plate 3. The four corners of the bottom of the isolation plate 13 are fixedly connected to the top of the lower pressure plate 3, and the limiting plates 8 are slidably connected to the surface of the isolation plate 13.

[0032] By adopting the above solution, by setting up the isolation plate 13, dust and debris can be effectively prevented from entering the container 4, thus keeping the internal components of the equipment clean and operating normally.

[0033] Referring to Figure 1, a number of anti-slip patterns 14 are provided on the top of the isolation plate 13, and the anti-slip patterns 14 are evenly distributed on the top of the isolation plate 13.

[0034] By adopting the above solution, the anti-slip texture 14 can significantly enhance the friction when the cardboard box is placed, preventing the cardboard box from sliding or shifting during the test, thereby ensuring the stability of the test process.

[0035] The working principle of this utility model:

[0036] In use, the cardboard box to be tested is first placed on top of the isolation plate 13. Then, the motor 11 is started, which drives the lead screw 10 to rotate. The lead screw 10 drives the rack 9 to move. Then, the rack 9 drives the gear 501 to rotate. The gear 501 drives the rotating rod 502 to rotate. Since the slider 7 is slidably connected to the inside of the through groove 6, the slider 7 can only move back and forth along the through groove 6. When the rotating rod 502 rotates, it will drive the connecting rods 503 on both sides to swing, thereby driving the slider 7 to move towards the side that is closer to each other. Then, the slider 7 drives the limiting plate 8 to move towards the side that is closer to each other along the stabilizing groove 12, thereby fixing the bottom of the cardboard box. After the cardboard box is fixed, the main body 1 of the compression testing machine is started to carry out subsequent testing work. The function of the isolation plate 13 is to prevent dust, debris and other impurities generated during the test from entering the receiving groove 4 and affecting the normal operation of the auxiliary components 5.

[0037] In summary, this lightweight packaging cardboard box strength testing device, through the coordinated use of the main body 1 of the compression testing machine, upper pressure plate 2, lower pressure plate 3, receiving groove 4, auxiliary components 5, through groove 6, slider 7, limiting plate 8, rack 9, lead screw 10, motor 11, stabilizing groove 12, isolation plate 13, and anti-slip texture 14, solves the problem that existing equipment often lacks effective clamping measures, making it difficult to securely and properly fix cardboard boxes of different sizes and shapes during cardboard box strength testing. This problem not only makes the cardboard boxes prone to displacement or tilting during testing, resulting in uneven stress and distorted test results, but also significantly increases the complexity of operation.
