Description

Technical Field

[0001] This application relates to the field of burst strength tester technology, specifically a device for testing the burst strength of aluminum foil packaging. Background Technology

[0002] The aluminum foil tear strength tester simulates the pressure experienced by aluminum foil in actual use and tests the maximum pressure it can withstand before tearing. During the test, the aluminum foil sample is fixed on the fixture of the tester, and the instrument applies gradually increasing pressure to the sample through a hydraulic or pneumatic system until the aluminum foil tears. The instrument records the maximum pressure value at the time of tearing, which is the tear strength of the aluminum foil.

[0003] For example, patent CN209707228U discloses a spherical bursting strength tester for toilet paper. The tester features a lubrication device designed inside to lubricate the surface of the pressure bar during operation, thus preventing friction from affecting the test results and effectively improving the accuracy of the bursting strength tester. Furthermore, the tester's surface includes a maintenance device that allows maintenance personnel to promptly troubleshoot and repair any malfunctions.

[0004] In the aforementioned patent, the device utilizes a lubrication system designed inside the bursting strength tester to facilitate lubrication of the pressure bar surface during operation, thereby improving the accuracy of the bursting strength tester. However, existing bursting strength testers rely entirely on manual movement of the material during loading and unloading to achieve testing at different locations. This process is cumbersome, requiring operators to continuously operate the device, frequently picking up, moving, and placing materials. This results in low overall testing efficiency. Therefore, it is necessary to provide a packaging aluminum film bursting strength testing device that can quickly load and unload materials to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a packaging aluminum film tear strength testing device to achieve the effect of rapid loading and unloading of materials to be tested.

[0007] The technical solution adopted by this application to solve its technical problem is: a packaging aluminum film tear strength testing device, including a base, a lower pressure platform fixedly installed on the top of the base, a hydraulic device provided inside the base, and an adhesive film installed inside the lower pressure platform; a connecting frame, which is fixedly installed on one side of the top of the base, a first cylinder is installed on the connecting frame, and an upper pressure platform is installed at the output end of the first cylinder; a material conveying assembly, which includes two sets of second cylinders, which are disposed at the bottom of the connecting frame, and a mounting frame is installed on the output end of the second cylinder, a motor is installed at one end of the mounting frame, and a rotating wheel is installed at the other end of the mounting frame.

[0008] Furthermore, the top of the base is provided with a feeding platform, and the feeding platform has a through hole, the size of which is adapted to the size of the lower pressing platform.

[0009] Furthermore, the outer side of the rotating wheel is provided with multiple sets of rubber protrusions.

[0010] Furthermore, a transparent baffle is installed on the outside of the connecting frame, the length of which is flush with the top of the feeding platform and leaves no gap.

[0011] Furthermore, a slot is provided on the inner side of the connecting frame.

[0012] The beneficial effects of this application are as follows: The packaging aluminum film tear strength testing device provided by this application achieves automatic and stable material conveying from the feeding platform to the testing position through the seamless docking of the feeding platform and the lower pressure platform, as well as the coordinated action of the second cylinder, the mounting frame, the motor and the rotating wheel. This not only improves the testing efficiency and accuracy, but also provides a strong guarantee for the optimization and upgrading of the production process.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-2 As shown, this application provides a packaging aluminum film tear strength testing device, including a tester 1. The tester 1 is installed in the packaging aluminum film production workshop and is used to sample and test a portion of the packaging aluminum film after production, thereby evaluating the overall product quality.

[0023] The tester 1 includes a base 11, which is placed and installed in the working position. A test component 2 is provided on the top of the base 11. The test component 2 includes a connecting frame 21, which is fixedly installed on one side of the top of the base 11. A photoelectric sensor is provided inside the connecting frame 21, which is used to confirm the position of the material.

[0024] Furthermore, a first cylinder 22 is fixedly installed on the connecting frame 21, and an upper pressure platform 23 is fixedly installed at the output end of the first cylinder 22. The bottom side of the upper pressure platform 23 is provided with holes, and a lower pressure platform 24 is fixedly installed on the top of the base 11. The top of the lower pressure platform 24 is also provided with holes, and the holes of the two are the same size and aligned with each other to ensure precise docking during testing. At the same time, a highly elastic adhesive film is fixedly installed in the hole on the top of the lower pressure platform 24 to provide necessary buffering and deformation space for subsequent rupture testing.

[0025] Furthermore, a hydraulic device is integrated inside the base 11. This hydraulic device is used to push the film upward under the control of the operator. It can also precisely control the upward pushing force of the film according to the test requirements, thereby simulating the pressure environment that may be encountered in actual use.

[0026] When a bursting test is required, the material to be tested is first placed on top of the lower pressure platform 24. Then, the first cylinder 22 drives the upper pressure platform 23 to press down, clamping the material between the upper pressure platform 23 and the lower pressure platform 24. At this time, the two sets of holes are aligned with each other, forming a closed test space. Then, the hydraulic components located inside the base 11 will push the diaphragm upward, causing the material to deform until it bursts.

[0027] Furthermore, during the entire testing process, a high-precision recording device is integrated inside the base 11. This device can capture and record the maximum load-bearing capacity when the sample breaks in real time, providing data support for subsequent quality analysis and improvement. The tester 1 is a traditional bursting strength tester. Its specific structure can be found in the patent with publication number CN207248613U, and will not be further limited here.

[0028] like Figures 2-3 As shown, in order to enable automated continuous testing of the same material, a material conveying assembly 3 is also provided on the base 11. The material conveying assembly 3 includes a feeding platform 31, which is detachably installed on the top of the base 11. A through hole is provided on the feeding platform 31, the size of which is adapted to the size of the lower pressure platform 24, so that the top of the feeding platform 31 can be at the same level as the top of the lower pressure platform 24, which facilitates subsequent testing.

[0029] Meanwhile, two sets of second cylinders 32 are fixedly installed at the bottom of the connecting frame 21 on both sides of the upper pressure table 23. The output end of the second cylinder 32 is set towards the discharge table 31, and a mounting frame 33 is fixedly installed on the output end of the second cylinder 32. A motor 34 is fixedly installed at one end of the mounting frame 33, and a rotating wheel 35 is fixedly installed at the other end of the mounting frame 33. The rotating wheel 35 is fixedly connected to the output end of the motor 34, so that the rotating wheel 35 can rotate under the drive of the motor 34. In addition, multiple sets of rubber protrusions (not shown in the figure) are provided on the outer side of the rotating wheel 35. These protrusions are used to increase the friction of the rotating wheel 35 and facilitate the conveying of materials.

[0030] Meanwhile, a slot 4 is provided on the inner side of the connecting frame 21, which is used to provide space for the movement of the motor 34.

[0031] Furthermore, when continuous testing of materials is required, the material is simply placed on top of the feeding platform 31. Then, the second cylinder 32 drives the rotating wheel 35 to contact the material, and the motor 34 drives the material to move towards the testing area. When the material reaches the testing position, the upper pressure platform 23 will descend under the recognition of the photoelectric sensor and press the material to perform the testing. When the material breaks at one set of positions, the rotating wheel 35 will continue to drive the material forward until all preset positions are tested, thus realizing automated continuous testing of the same material.

[0032] like Figures 1-2 As shown, in order to prevent the material from shifting under the drive of the roller 35, a transparent baffle 5 is hinged to the outside of the connecting frame 21. The length of the baffle 5 is flush with the top of the feeding platform 31 in the initial state without leaving any gaps. When the shifted material comes into contact with the baffle 5, it will be significantly obstructed. This obstruction will force the material to gradually return to the original conveying path, thereby avoiding problems such as test interruption or inaccurate data caused by the shift.

[0033] In summary, this device, through the seamless connection between the feeding platform 31 and the lower pressure platform 24, and the coordinated action of the second cylinder 32, the mounting frame 33, the motor 34 and the rotating wheel 35, realizes the automatic and stable conveying of materials from the feeding platform to the testing position. This not only improves the testing efficiency and accuracy, but also provides a strong guarantee for the optimization and upgrading of the production process.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
