Description

Technical Field

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

[0002] Cartons are used to store goods and seal, protect and support the goods. They can effectively resist vibration, extrusion and collision during the transportation and handling of goods, and play a buffering role in the collision of goods. Therefore, the quality of cartons is particularly important. For waterproof cartons, a waterproof layer is attached to the inner wall of the carton to prevent liquid leakage and soaking of the carton when transporting wet objects, affecting its strength. When testing the quality of the waterproof layer, a common test method is to pour water directly into the carton and observe the water seepage of the carton.

[0003] When using the existing press for carton strength testing, in order to keep the carton tilted during the tilted compression test, the tester needs to support the carton to maintain a certain tilt angle. If the press loses control during the test, it is easy to cause work-related accidents. In the test of existing waterproof cartons, the compressive strength of the carton after being damp is also an important indicator of carton quality. Cartons with good moisture resistance can provide good support and protection for goods stored or transported in a humid environment. In the existing carton moisture resistance strength test, the humidification method for the carton is generally spraying or soaking in water. The cartons are humidified to simulate the natural moisture of the cartons, but this method does not humidify the cartons evenly enough and the humidification intensity is difficult to control, resulting in uneven humidification of the cartons, which will have a certain impact on the test results; in the sealing test of the waterproof layer on the inner surface of the carton, the humidification process of the carton is too aggressive by the detection method of injecting water into the carton. The waterproof layer of the carton is prone to leakage under the action of water pressure, or leakage through the edge of the waterproof layer, which is inconsistent with the actual application environment of the waterproof carton. The waterproof layer of the carton cannot be lightly humidified for a long time to simulate the environment in which the carton stores and transports wet objects in actual applications. Summary of the invention

In this state, the compression test press machine 2 is controlled to move, so that the test press plate 15 moves downward to apply pressure to the carton, and the support control motor 6 is controlled to move while the press plate anti-skid pad layer 1501 contacts the upper edge of the carton, driving the active gear 7 to rotate, and the rotating bracket 8 is tilted forward and stored in the storage port 303 through the gear rack transmission of the active gear 7 and the arc rack 801, and separated from the carton to avoid affecting the strength test of the carton; by applying pressure to the edge of the carton, observing the deformation of the carton and the detection pressure data of the pressure sensor 14, and then obtaining the edge compressive strength of the carton, similarly, the top corner of the carton is facing downward to contact with the placement table anti-skid pad layer 301, and the edge of the carton is facing the rotating support frame 804, so that the inclined surface of the inner oblique support plate 805 is in contact with the adjacent two surfaces of the carton, which can keep the top corner of the carton in contact with the carton placement table 3, and test the edge compressive strength of the carton to measure the multi-directional strength of the carton and measure the comprehensive strength data of the carton.

[0043] Embodiment 2, on the basis of embodiment 1, a pressure plate anti-skid pad layer 1501 is fixedly connected to the lower surface of the test pressure plate 15, and a convex point structure is provided on the lower surface of the pressure plate anti-skid pad layer 1501, and an exhaust hole 1502 is longitudinally penetrated on the test pressure plate 15; the exhaust hole 1502 also longitudinally penetrates the pressure plate anti-skid pad layer 1501, and the exhaust hole 1502 is located directly above the humidification socket 302; through the setting of the pressure plate anti-skid pad layer 1501, an anti-skid effect is achieved, which is mainly used for testing tilted boxes to prevent the box from slipping and detaching from the support of the inner diagonal support plate 805.

[0044] Working principle of this embodiment: When the carton strength test device is used to test the strength of the carton, the carton is placed on the top of the carton placement table 3, the compression test press 2 is controlled to move, and the test platen 15 is pushed downward. After the test platen 15 contacts the carton, the compression test press 2 continues to apply pressure to the pressure sensor 14 and the test platen 15, and the pressure change of the pressure sensor 14 is displayed on the control panel 12. The deformation of the carton and the pressure detection change of the control panel 12 are observed to obtain the compressive strength of the carton; when performing the compression test on the edges of the carton, the extension length of the lifting inner rod 803 in the rotating bracket 8 is manually adjusted, and the inclination angle of the rotating support 804 is manually adjusted to make the edges of the carton and the anti-slip pad 301 of the placement table. The carton is supported by the inner diagonal support plate 805, and the carton is kept tilted. In this state, the compression test press 2 is controlled to move, so that the test press plate 15 moves downward, and pressure is applied to the carton. At the same time, the anti-skid pad layer 1501 of the press plate contacts the upper edge of the carton, the bracket control motor 6 controls the rotating bracket 8 to separate from the carton to avoid affecting the strength test of the carton. By applying pressure to the edge of the carton, the deformation of the carton and the pressure data detected by the pressure sensor 14 are observed, and the compressive strength of the edge of the carton is obtained. Similarly, the top corner of the carton is facing downward to contact the anti-skid pad layer 301 of the placement table, and the edge of the carton is facing the rotating support frame 804, so that the inner diagonal support plate 805 The inclined surface is fitted with the two adjacent surfaces of the carton, which can keep the top corner of the carton in contact with the carton placement table 3, and test the compressive strength of the edges and corners of the carton to measure the multi-directional strength of the carton, and measure the comprehensive strength data of the carton. When the carton is tested for moisture resistance, the two humidifying rotating tubes 9 are rotated upward to make the surrounding arc tube 901 flush with the carton. In this state, the external humidifying atomizing pump 10 is controlled to start, and water mist is transported to the humidifying rotating tube 9 through the external humidifying atomizing pump 10. The water mist passes through the humidifying rotating tube 9 and the surrounding arc tube 901 and is sprayed toward the carton through the mist nozzle 902, so that the carton is evenly humidified. The moisture state of the carton can be simulated to test the moisture resistance of the carton. When testing the waterproof layer inside the box, the box body is covered with a mist. The upper and lower ends are opened, and the humidifying nozzle 4 is rotatably installed on the humidifying socket 302, so that the tapered end of the humidifying nozzle 4 is inserted into the opening of the box, and the upper opening of the box is aligned with the exhaust hole 1502, so that the test plate 15 is in contact with the top surface of the box, and water mist is delivered to the humidifying nozzle 4 through the internal humidifying atomizing pump 5, and water mist is applied to the inside of the carton through the humidifying nozzle 4 to humidify the inside of the box. At the same time, the water mist that continues to enter the box is discharged through the exhaust hole 1502 to prevent the box from being affected by the water mist continuously applied inside and increasing the internal pressure of the box, thereby affecting the waterproof state of the waterproof layer under normal pressure. The humidity inside the carton increases, which is used to simulate the state of the carton when storing wet objects, and cooperates with the pressure test press 2 to detect the performance of the waterproof layer inside the carton.
