Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, and in particular to a compression resistance testing device for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are the most widely used packaging product, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also serve to beautify and promote products.

[0003] After corrugated cardboard boxes are manufactured, they need to undergo a compression resistance test to ensure that they will not deform or collapse during packaging and stacking, thus preventing unnecessary damage. During the use of existing corrugated cardboard box testing equipment, the following problems were found in the current technology, which have not been adequately resolved:

[0004] Existing testing devices mostly fix the cardboard box on both sides, but this fixing structure supports the cardboard box, resulting in inaccurate test results. Secondly, the cardboard box often deforms after the compression test, requiring staff to manually reset the cardboard box, which is cumbersome. Utility Model Content

[0005] To address the aforementioned issues where the fixing structures on both sides of the cardboard box easily support the box, resulting in inaccurate compression test data and requiring manual repositioning after deformation, this utility model provides a compression test device for corrugated cardboard box production.

[0006] This utility model provides a compression testing device for corrugated cardboard box production, which adopts the following technical solution:

[0007] A compression resistance testing device for corrugated cardboard box production includes a main body of the device. An adjusting screw is connected inside the main body of the device. A threaded block is connected to the center of the adjusting screw. A reset block is connected above the threaded block. A center opening is opened in the center of the reset block. A protective layer is connected to the inner side of the reset block. A laser rangefinder is set on the outer side of the reset block. The cardboard box body is set in the center of the reset block.

[0008] A top plate is provided above the main body of the carton, an electric push rod is connected below the top plate, a bottom plate is connected below the electric push rod, a rubber block is also provided below the main body of the carton, a return spring is connected below the rubber block, an adsorption port is connected to the center of the rubber block, and an adsorption mechanism is connected below the adsorption port.

[0009] The above technical solution facilitates the repositioning of the carton body after the compression test by adjusting the lead screw and the reset block. The laser rangefinder ensures a good repositioning effect, and the adsorption structure at the bottom fixes the carton body in place, preventing any impact on the accuracy of the test results during use.

[0010] Optionally, in the above-mentioned compression testing device for corrugated cardboard box production, the connection between the main body of the device and the adjusting screw is a rotary connection, the connection between the adjusting screw and the threaded block is a threaded connection, and the threaded block and the reset block are integrated into a single installation structure.

[0011] The above technical solution facilitates the movement of the threaded block by adjusting the lead screw, thereby enabling the reset block to move automatically to the center.

[0012] Optionally, in the above-mentioned compression testing device for corrugated cardboard box production, the center of the reset block coincides with the center of the center opening, the center of the center opening is at the same horizontal line as the center of the laser rangefinder, and the reset block and the protective layer are installed as an integral unit.

[0013] The above technical solution facilitates the repositioning of the carton body after compression by using the reset block in conjunction with the protective layer.

[0014] Optionally, in the above-mentioned compression testing device for corrugated cardboard box production, the center of the cardboard box body coincides with the center of the device body, and a support block is also provided below the cardboard box body. The support block is distributed in a U-shape below the center of the cardboard box body.

[0015] The above technical solution facilitates the use of support blocks to support the bottom outer side of the carton body, preventing the carton body from sinking around its edges.

[0016] Optionally, in the above-mentioned compression testing device for corrugated cardboard box production, a drive mechanism is provided on the other side of the electric push rod, the electric push rod is integrally installed with the base plate, and the size of the base plate is larger than the size of the cardboard box body.

[0017] The above technical solution facilitates the lifting and lowering of the base plate via an electric push rod, thereby enabling pressure testing.

[0018] Optionally, in the above-mentioned compression testing device for corrugated cardboard box production, the rubber block is integrated with the adsorption mechanism through the adsorption port, and the rubber block is integrated with the device body through the return spring to form a spring return structure, with the center of the rubber block coinciding with the center of the cardboard box body.

[0019] The above technical solution facilitates the use of a rubber block and a return spring to allow the rubber block to adhere to the bottom of the carton body, thus completing the adsorption of the carton body.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By setting a rubber block and an adsorption mechanism at the center of the main body of the device, the rubber block is adsorbed onto the bottom of the carton body. The negative pressure is used to fix the carton body, avoiding inaccurate test results caused by supporting the carton body during the compression test. At the same time, a return spring is connected below the rubber block, so that the rubber block fits into the carton body and ensures a stable fixation.

[0022] By setting reset blocks on both sides of the carton body, after the carton body undergoes deformation during the compression test, the reset blocks clamp the carton body, allowing it to return to its original shape. At the same time, a center opening is provided in the center of the reset block, allowing the laser rangefinder to measure the position of the carton body, ensuring the accuracy of the reset.

[0028] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figures 1-4This utility model provides an embodiment of a compression testing device for corrugated cardboard box production, comprising a device body 1, an adjusting screw 3 connected inside the device body 1, a threaded block 2 connected to the center of the adjusting screw 3, and a reset block 4 connected above the threaded block 2. The reset block 4 cooperates with the center opening 7 to reset the deformed cardboard box body 9. The center opening 7 is provided in the center of the reset block 4, a protective layer 6 is connected to the inner side of the reset block 4, and a laser rangefinder 5 is provided on the outer side of the reset block 4. The laser rangefinder 5 is used to measure the position of the cardboard box body 9 to ensure the accuracy of the reset. The cardboard box body 9 is located at the center of the reset block 4.

[0030] A top plate 12 is provided above the main body 9 of the carton. An electric push rod 10 is connected below the top plate 12. A bottom plate 11 is connected below the electric push rod 10. The bottom plate 11 and the electric push rod 10 cooperate to compress the main body 9 of the carton, thereby conducting a compression test. A rubber block 13 is also provided below the main body 9 of the carton. A return spring 14 is connected below the rubber block 13. The return spring 14 supports the rubber block 13 to ensure sealing. An adsorption port 16 is connected to the center of the rubber block 13. An adsorption mechanism 8 is connected below the adsorption port 16.

[0031] Working principle: In use, first, place the carton body 9 above the device body 1. At this time, the support block 15 is located around the center of the carton body 9, and the rubber block 13 is located in the center of the carton body 9. Then, turn on the switch in the adsorption mechanism 8 to make the adsorption device start to draw air, so that the adsorption port 16 and the rubber block 13 start to generate negative pressure, thus completing the limiting and fixing of the carton body 9. After that, turn on the switch of the electric push rod 10 to make the bottom plate 11 descend and squeeze the carton body 9 to start the compression test.

[0032] As described above, after the compression test is completed, the carton body 9 deforms. At this time, the switch of the adjusting screw 3 is turned on, so that the adjusting screw 3 and the threaded block 2 move in a threaded motion, thereby driving the reset block 4 to move towards the center until the reset block 4 contacts the carton body 9 and continues to move. At the same time, the switch of the laser rangefinder 5 is turned on. When the reset block 4 pushes the carton body 9 back to the distance before the compression test, the rotation of the adjusting screw 3 is stopped. The adjusting screw 3 is rotated in the opposite direction to reset the reset block 4.

[0033] It should be further explained that the connection between the main body 1 and the adjusting screw 3 is a rotary connection, and the connection between the adjusting screw 3 and the threaded block 2 is a threaded connection. The threaded block 2 and the reset block 4 are integrated into one structure. The adjusting screw 3 drives the threaded block 2 to move, thereby the reset block 4 moves automatically to the center.

[0034] It should be noted that the center of the reset block 4 coincides with the center of the center opening 7, and the center of the center opening 7 is at the same horizontal line as the center of the laser rangefinder 5. The reset block 4 and the protective layer 6 are installed as an integral unit. The reset block 4 and the protective layer 6 work together to reset the carton body 9 after it has been subjected to pressure.

[0035] It should be noted that the center of the carton body 9 coincides with the center of the device body 1. A support block 15 is also provided below the carton body 9. The support block 15 is distributed in a U-shape below the center of the carton body 9. The support block 15 is used to support the bottom outer side of the carton body 9 to prevent the carton body 9 from sinking around.

[0036] It should be noted that a drive mechanism is provided on the other side of the electric push rod 10. The electric push rod 10 and the base plate 11 are installed as an integral part. The size of the base plate 11 is larger than the size of the carton body 9. The electric push rod 10 drives the base plate 11 to rise and fall, thereby carrying out the compression test.

[0037] It should be further explained that the rubber block 13 forms an integrated installation structure with the adsorption mechanism 8 through the adsorption port 16. The rubber block 13 forms a spring reset structure with the device body 1 through the reset spring 14. The center of the rubber block 13 coincides with the center of the carton body 9. Through the cooperation of the rubber block 13 and the reset spring 14, the rubber block 13 is attached to the bottom of the carton body 9, thus completing the adsorption work of the carton body 9.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
