Description

Technical Field

[0001] This utility model relates to the field of cardboard box strength testing technology, and in particular to a cardboard box pressure testing device. Background Technology

[0002] A common cardboard box pressure testing device is the vertical pressure tester (also called a cardboard box compression tester). This device is mainly used to test the strength and durability of cardboard boxes under pressure during stacking or transportation. Its working principle involves placing the cardboard box on a test platform and applying vertical pressure through a hydraulic system or electric device to simulate the pressure experienced by the cardboard box during actual transportation or stacking. This test helps assess the load-bearing capacity of the cardboard box, thereby ensuring that the packaging is not easily damaged during transportation and storage. This equipment is widely used in the packaging industry, especially playing an important role in improving quality control and product packaging design.

[0003] In actual production and use, the existing device lacks adjustability. For cartons of different sizes, the existing device may not be able to accurately adapt, which may lead to inaccurate or inconvenient test results. Therefore, this invention sets up an adjustable support platform that can automatically adjust according to the size of the cartons to ensure that the cartons are always in the appropriate position during the test. At the same time, the existing device only has a single pressure detection structure, which will lead to a decrease in detection efficiency when a batch of cartons needs to be inspected. Therefore, this invention sets up a rotatable support platform, which can replenish the cartons to be inspected while testing, greatly improving the detection efficiency of the device. At the same time, it can detect a large number of cartons of the same batch under different pressure values, which is convenient for subsequent averaging and reduces the final error.

[0004] Therefore, we propose a carton pressure testing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. In actual production, due to a lack of adjustability, existing devices may not be able to accurately adapt to cartons of different sizes, thus affecting the accuracy of testing or the convenience of operation. Therefore, this invention provides an adjustable support platform that automatically adjusts according to the size of the cartons, ensuring that the cartons remain in the correct position throughout the testing process. Furthermore, existing devices only have a single pressure detection function, which leads to low testing efficiency when conducting batch quality inspections of cartons. To solve this problem, this invention designs a rotatable support platform, enabling the simultaneous testing and replenishment of cartons to be tested, thereby significantly improving testing efficiency. It also allows for the testing of a large number of cartons from the same batch under different pressure values, facilitating subsequent averaging and reducing final errors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A carton pressure testing device includes a base, a first worm gear rotatably connected to the inside of the base via a bearing, one end of the first worm gear being fixedly connected to the output end of a motor, a first rotating shaft being provided on one side of the first worm gear, the first rotating shaft being rotatably connected to the inside of the base via a bearing, a first worm wheel being coaxially fixedly connected to the outer periphery of the first rotating shaft, the first worm gear and the first worm wheel meshing, and a tray being coaxially fixedly connected to the end of the first worm wheel away from the first worm wheel.

[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a carton pressure testing device, including a base 1, which bears the weight of all the main components and provides rotational support for the first worm 2 and the first rotating shaft 4 through internal bearings. The first worm 2 is rotatably connected to the inside of the base 1 through bearings. One end of the first worm 2 is fixedly connected to the output end of the motor. The first rotating shaft 4 is provided on one side of the first worm 2. The first rotating shaft 4 is rotatably connected to the inside of the base 1 through bearings. The outer periphery of the first rotating shaft 4 is coaxially fixedly connected to the first worm wheel 3. The first worm 2 and the first worm wheel 3 mesh with each other. When the first worm 2 and the first worm wheel 3 mesh, the first worm wheel 3 rotates under the push of the first worm 2 to complete the power conversion. The end of the first worm wheel 3 away from the first worm wheel 3 is coaxially fixedly connected to the tray 5 for supporting the support platform 6.

[0028] A support platform 6 is coaxially fixedly connected to the top of the tray 5. A slide rail 12 is fixedly installed on the top of the support platform 6. A slider 13 is slidably connected to the side of the slide rail 12 away from the support platform 6. A clamping block 14 is fixedly installed at the end of the slider 13 away from the slide rail 12. The clamping block 14 is a key structure in the device for fixing the carton. After being fixedly installed on the slider 13, it can slide along the slide rail 12 with the slider 13 to adjust its position. The two clamping blocks 14 are adapted to form a clamping system for the object. The distance and shape between the clamping blocks 14 can be adjusted or designed according to the size and shape of the carton. When the clamping blocks 14 move towards each other, they clamp the carton to ensure that the carton is stable and does not loosen.

[0029] A rotating disk 11 is provided at the bottom of the clamping block 14. A groove is provided inside the rotating disk 11. The clamping block 14 is slidably connected in the groove. The rotating disk 11 provides the clamping block 14 with opposite movement, so that the clamping block 14 can flexibly adjust the clamping range of the object. A second rotating shaft 7 is coaxially fixedly connected to the bottom of the clamping block 14. The end of the second rotating shaft 7 away from the rotating disk 11 is rotatably connected to the inside of the support platform 6 through a bearing to ensure smooth shaft rotation during rotation and reduce friction and wear. A second worm gear 8 is coaxially fixedly connected to the outer periphery of the second rotating shaft 7. A second worm 9 is provided on one side of the second worm gear 8. The second worm 9 is connected to the inside of the support platform 6 through a bearing. The second worm gear 8 and the second worm 9 mesh with each other to convert and control the rotation of the rotating disk 11.

[0030] A knob 10 is coaxially fixedly connected to one side of the second worm gear 9, providing a manual adjustment method to control the rotation of the second worm gear 9. Support seats 15 are fixedly installed on both sides of the base 1. A telescopic rod 16 is fixedly installed on the top of the support seat 15, providing stable support for the entire device through fixed installation. The telescopic rod 16 on the top of the support seat 15 provides adjustable support in the vertical direction, allowing the connecting crossbar 17 to be raised and lowered as needed. The end of the telescopic rod 16 away from the support seat 15 is fixedly connected to the connecting crossbar 17. A connecting column 18 is fixedly installed at the bottom of the connecting crossbar 17. A fixing plate 19 is fixedly installed at the end of the connecting column 18 away from the fixing plate 19. Multiple pressure sensors are fixedly installed at the bottom of the fixing plate 19, evenly distributing the pressure onto the sensors. A pressure plate 20 is in close contact with the pressure sensors, ensuring that the pressure sensors can accurately sense pressure changes. The pressure plate 20 is fixedly installed at the bottom of the pressure sensors.

[0031] The working process of this utility model:

[0032] Step 1: When the carton needs to be inspected, place the carton on the support platform 6. Rotate the knob 10 to control the rotation of the second worm gear 9 installed inside the support platform 6. Since the second worm gear 9 meshes with the second worm wheel 8, it drives the rotation of the second worm wheel 8. At the same time, the second rotating shaft 7 is coaxially fixedly connected inside the second worm wheel 8. The rotation of the second worm wheel 8 drives the rotating disk 11 at the top of the second rotating shaft 7 to rotate. Since the rotating disk 11 has a groove for the clamping block 14 to slide, the clamping block 14 can move with the rotation of the rotating disk 11. The bottom of the clamping block 14 is fixedly installed with a slider 13 and can slide to the top of the slide rail 12, so that when the rotating disk 11 rotates, the clamping block 14 can perform a clamping action. The knob 10 is used to control the fixing of cartons of different models and sizes.

[0033] Step 2: During the test, the connecting crossbar 17 moves by the lifting and lowering motion of the telescopic rod 16, causing the connecting column 18 fixedly installed at the bottom of the connecting crossbar 17 to move. This causes the fixed plate fixedly installed at the bottom of the connecting column 18 to move downwards. When the pressure plate 20 set at the bottom of the fixed plate 19 contacts the surface of the carton, multiple pressure sensors fixedly installed between the fixed plate 19 and the pressure plate 20 will receive pressure signals. As the pressure plate 20 moves downwards, the pressure on the carton under different pressure conditions is detected, and the values ​​of multiple cartons are measured. The average value is then taken to obtain the final measurement data.

[0034] Step 3: During the testing process, repeat the steps in Step 1. By replacing multiple sets of cartons, the first worm gear 2 controlled by the motor drives the first worm wheel 3 meshing with it to rotate. Consequently, the first rotating shaft 4, which is coaxially fixed inside the first worm wheel 3, also rotates, causing the tray 5, which is coaxially fixed to the top of the first rotating shaft 4, to rotate. Since a support platform 6 is fixedly installed on the top of the tray 5, the support platform 6 can also rotate. In this way, by testing while replenishing the cartons to be tested, the testing efficiency is improved.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
