Technical Field

[0001] The present application relates to the technical field of carton compression testing, and in particular to a carton compression testing device. Background Art

[0002] Cartons need to go through a compression test procedure during production and use, which can effectively test the compression quality of the cartons. After the test is completed, staff are generally required to remove the cartons that are deformed by compression on the load plate.

[0003] However, since the carton compression test is conducted on the top and bottom surfaces of the carton as a whole, the area of ​​the pressure plate and the load-bearing plate is much larger than the top surface area of ​​the carton. Therefore, in actual use, when removing the tested carton from the load-bearing plate, workers are often required to bend over or squat to pick up the carton and transport it to the designated area. Doing this for a long time can easily cause physical fatigue. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a compression test device for a carton. Figure 1-3 A compression testing device for cartons includes a workbench 1, a gantry is installed in the upper middle part of the workbench 1, a lifting and feeding system 2 is installed on the gantry, and the movable end of the lifting and feeding system 2 is connected to a pressure measuring component 3. The lifting and feeding system 2 drives the pressure measuring component 3 to move, so that the pressure measuring component 3 moves up and down along the Z axis to complete the compression test of the carton.

[0021] Reference Figure 3The pressure measuring assembly 3 includes a support frame 301 installed at the movable end of the lifting feed system 2. Four detachable force sensors 303 are installed below the support frame 301. For example, through bolt connection, the lower end of the force sensor 303 is installed with a force sensor 303. Four threaded rods 304 are installed on the force sensor 303. The upper ends of the threaded rods 304 pass through the support frame 301 and are slidably connected to the support frame 301. The upper ends of the threaded rods 304 are threadedly installed with locking nuts 305. By adjusting the height of the locking nuts 305 relative to the threaded rods 304, the distance between the pressure plate 302 and the support frame 301 is changed. A level 5 is installed on the pressure plate 302 to assist in adjusting the position of the pressure plate 302 by detecting the horizontality of the pressure plate 302. The threads between the threaded rods 304 and the locking nuts 305 can achieve self-locking. The self-locking conditions of the threads depend on the helical angle of the threads, the friction coefficient, and the load they are subjected to. The self-locking condition for threads can be calculated using the following formula: Self-locking condition = Friction coefficient × tan(helix angle) ≥ Table 1. When this condition is met, the threaded connection is self-locking. The above information is based on existing technology. In actual applications, the corresponding self-locking angle can be set based on the material's friction coefficient, so this will not be elaborated here.

[0022] Reference Figure 3 , both sides of the workbench 1 are equipped with a loading positioning assembly 4, and a plurality of telescopic cylinders 401 are also installed on the bracket 402. The fixed end of the telescopic cylinder 401 is detachably connected to the workbench 1, and the movable end of the telescopic cylinder 401 is installed with a bracket 402. An electric conveying device is installed on the two brackets 402. The electric conveying device can be selected from an electric conveying roller group or an electric conveyor belt according to needs. For example, the electric conveyor belt includes a plurality of conveying rollers 403 rotatably mounted on the bracket 402, and the outer side of the plurality of conveying rollers 403 is provided with a same conveyor belt 404. The side of the bracket 402 A driving motor 405 is installed on the surface, and the outermost conveying roller 403 is connected to the driving motor 405 through a transmission component. By placing the carton on the inner side of the two brackets 402, the telescopic cylinder 401 is used to drive the bracket 402 to move and clamp the carton, and then the driving motor 405 drives the conveyor belt 404 to rotate, so that the conveyor belt 404 rotates to drive the carton to move, realizing the loading and unloading operations of the carton, without the need for staff to bend down to pick up the carton from under the pressure plate, and the conveyor belt 404 can also limit the carton to prevent the carton from offsetting during testing and affecting the test results.

[0023] The implementation principle of the compression test equipment for cartons in the embodiment of the present application is as follows:

[0024] Place the carton to be tested in the equipment's designated loading area, typically between the two sides of the loading and positioning assembly. Activate the loading and positioning assembly 4, and the telescopic cylinder 401 begins operating, pushing the bracket 402 toward the carton. When the conveyor rollers 403 or conveyor belt 404 on the bracket contact the carton, the telescopic cylinder 401 stops operating, and the drive motor 405 rotates the conveyor belt 404, moving the carton toward the testing area. Once the carton is precisely positioned in the testing area, the drive motor 405 stops operating, and the conveyor belt 404 stops rotating, securing the carton.

[0025] The lifting and feeding system 2 is activated, driving the load cell 3 downward along the Z-axis. The pressure plate 302 in the load cell gradually approaches the carton until it contacts the top and applies pressure. This pressure is transmitted through the pressure plate 302 to the load cell 303, which measures and records the pressure applied to the carton in real time. Depending on the test requirements, the lifting and feeding system 2 can continue applying pressure until a preset threshold is reached or until the carton deforms or breaks.

[0026] Load cell 303 transmits the measured pressure data in real time to a control system or data processing unit. The control system processes and analyzes the received data, generating a test report or chart demonstrating the carton's compressive performance. After the test is complete, the lifting and feeding system drives the load-measuring assembly back to its initial position.

[0027] The driving motor 405 is started again, and the direction of conveying the carton moves out from the rear of the equipment for the next round of testing.
