[0003] At present, the equipment for vibration resistance testing of corrugated cardboard boxes mainly adopts automobile driving simulation vibration meter, which can simulate the vibration of corrugated cardboard boxes during transportation. Since the automobile driving simulation vibration meter drives the clamp to make a U-shaped motion through the internal motor, the vibration generated in this way is a regular vibration, which deviates greatly from the actual automobile driving vibration, and the obtained vibration parameters are of poor accuracy. At the same time, the corrugated cardboard box is clamped and fixed by a clamp. During the vibration process, the clamp pressure on the corrugated cardboard box depends on the rotation speed of the automobile driving simulation vibration meter, and it is impossible to control a single variable.

The vibration motor can change the speed to produce different vibration effects.

[0016] Compared with the prior art, the present invention has the following advantages: 1. During the corrugated box inspection process, the device can drive the support frame and the components installed on the support frame to perform irregular swinging motion by setting a vibration motor, a universal rotating ball and a connecting shaft. The vibration generated in this way is irregular vibration, which is more similar to the vibration during the operation of a car. At this time, the vibration parameters obtained by the detection are more realistic and more accurate.

[0017] 2. During the corrugated box inspection process, this device can simulate the vibration reduction system of the car during operation by setting the limit spring, the second pressure spring and the trapezoidal spring, provide a certain degree of buffering for the corrugated box, further fit the actual inspection form, and the obtained vibration parameters are more valuable for reference.

[0018] 3. During the corrugated cardboard box detection process, this device can simulate the changes in the pressure force between corrugated cardboard boxes during transportation by setting up an electric telescopic rod, a horizontal sensor, a pressure spring and a pressure lead block. The low pressure can be automatically changed according to the amplitude of vibration, so that the detection is more in line with the realistic vibration simulation and the obtained vibration parameters are more accurate.

[0019] In summary, the present invention simulates the actual vibration of corrugated boxes during transportation through irregular swinging, and also changes the force applied to each supporting angle of the corrugated boxes during the vibration process, thereby achieving the most realistic simulation of the vibration of corrugated boxes during transportation. The obtained vibration parameters are also more in line with reality and have a higher reference value. BRIEF DESCRIPTION OF THE DRAWINGS

10. A method for detecting simulated transport vibration of corrugated paper boxes, characterized in that: The detection device according to claim 9 further comprises the following steps: S1. First, turn on the electric telescopic rod (16), and adjust the distance between the two bottom cross beams (13) and the two top cross beams (14) through the driving end of the electric telescopic rod (16), so that the positions of the two inner angle irons (30) located on the bottom cross beams (13) and the two top cross beams (14) are equal to the width of the corrugated paper box (12), and at this time, the edge of the inner angle iron (30) is flush with the edge of the corrugated paper box (12); S2, then manually adjust the position of the fixing clamp (27) so that the spacing between the inner angle irons (30) located on the same bottom crossbeam (13) and the two top crossbeams (14) is equal to the length of the corrugated paper box (12), and then place the corrugated paper box (12) on the placement plate (22). At this time, the multiple inner angle irons (30) located on the bottom crossbeam (13) are respectively attached to the four bottom corners of the corrugated paper box (12), just wrapping the four corners of the corrugated paper box (12) in the corresponding inner angle irons (30). After the adjustment is completed, use bolts to lock the fixing clamp (27); S3, turning on the electric push rod (9), the driving end of the electric push rod (9) moves downward, driving the connecting frame (10) to move downward, driving the two top longitudinal beams (11) to move downward through the pillars, thereby driving the inner angle irons (30) on the two top cross beams (14) to move downward, so that the inner angle irons (30) on the top cross beams (14) are attached to the four top corners of the corrugated paper box (12), and the four corners are wrapped; S4, after the above S1-S3 are completed, the corrugated paper box (12) is in a clamped and fixed state, and the position of the fixing plate (18) is adjusted according to the total weight of the corrugated paper box (12) so that the pressing lead block (23) and the corresponding outer angle iron (25) are pressed against each other; S5, then start the vibration motor (3), the vibration motor (3) drives the universal rotating ball (15) to rotate, and drives the support frame (5) to rotate through the connecting shaft (31), thereby driving the two bottom longitudinal beams (6) fixedly connected to the support frame (5) to rotate irregularly, simulating the vibration of the car during driving. With the operation of the vibration motor (3), the support frame (5) will tilt to different degrees and in different directions. During the tilting process, the pressure lead block (23) will slide, overcome the elastic force of the pressure spring 1 (19), and generate a pressure force (the force is a lateral force) on the outer angle iron (25). The pressure force can act on the inner angle iron (25) through the pressure spring 2 (29). The angle iron (30) is then transmitted to the corrugated paper box (12) through the inner angle iron (30). At the same time, the horizontal sensor (17) controls the extension of the driving end of the electric telescopic rod (16) according to the tilt angle, the horizontal and longitudinal spacing between the two sets of outer angle irons (25), and then acts on the inner angle iron (30) through the inner angle iron (30) to act on the corrugated paper box (12), thereby changing the lateral and longitudinal compressive forces on the eight corners of the corrugated paper box (12), simulating the compressive forces generated between the corrugated paper boxes (12) during transportation, and the vibration motor (3) can change the rotation speed to produce different vibration effects.
