All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 10The present invention provides a technical solution: a multi-layer shockproof universal carton shockproof testing device, comprising a test bench 1, a control cabinet 2 is installed on the side of the test bench 1, an observation screen 3 is provided on the top of the control cabinet 2, a simulation bin 4 is fixedly installed on the top of the test bench 1, a connecting seat 5 is fixedly installed on the inner bottom of the test bench 1, an active motor 6 is installed on the top of the connecting seat 5, and a rotating shaft 7 is fixedly connected to the output end of the active motor 6. By setting the simulation bin 4 structure and providing different collision blocks on the inside of the simulation bin 4, it can better simulate the collision, friction, scratching and other phenomena that the carton may encounter during actual transportation, thereby more accurately evaluating the shockproof performance of the carton.

[0029] A rotating disk 8 is fixedly sleeved on the side of the rotating shaft 7. The rotating shaft 7 passes through the top of the rotating disk 8, and a driving bevel gear 23 is fixedly installed on the top of the rotating shaft 7. Two brackets 24 are fixedly installed on the top of the rotating disk 8. The side of the bracket 24 is rotatably connected to a synchronization rod 25. The side of the synchronization rod 25 is sleeved with a vibration gear 26. The side of the synchronization rod 25 is sleeved with two sets of symmetrical driven bevel gears 27. The driven bevel gear 27 is meshed with the driving bevel gear 23 for transmission.

[0030] Multiple sets of hinge seats 9 are fixedly installed on the side of the rotating disk 8, and the side of the hinge seat 9 is rotatably connected to a connecting rod assembly. The side of the connecting rod assembly is equipped with a first control motor 10, and the output end of the first control motor 10 is plugged and rotated on the side of the hinge seat 9.

[0031] The top of the connecting rod assembly is rotated with a synchronous disk 11, and a smooth groove 12 is provided on the top of the synchronous disk 11, and the top of the smooth groove 12 is slidably matched with a clamping disk 13. Multiple groups of telescopic rods 14 are fixedly installed on the top of the clamping disk 13, and a tension spring 15 is provided on the side of the telescopic rod 14. The clamping disk 13 is fixedly connected to the placement disk 16 through the telescopic rod 14. The carton 17 to be tested is placed on the top of the placement disk 16. The tension spring 15 connects the clamping disk 13 and the placement disk 16. When the second motor is started, it can drive the cam to rotate. The cam is fitted and connected to the placement disk 16 to produce an up and down vibration effect. At the same time, the tension spring 15 and the telescopic rod 14 connect the placement disk 16 and the clamping disk 13. The structural combination is tighter and the vibration effect is smoother.

[0032] The connecting rod assembly includes a first connecting rod 28, the top of the first connecting rod 28 is rotatably connected to the second connecting rod 29, and the bottom rotating shaft of the first connecting rod 28 is synchronously connected to the output end of the first control motor 10. The structural design of the connecting rod assembly links the rotating disk 8 and the synchronous disk 11, and when the first control motor 10 drives the first connecting rod 28 to rotate, under the transmission effect of the connecting rod assembly, the synchronous disk 11 is driven to present different inclination angles.

[0033] The bottom clamping block 18 of the clamping disk 13 can be buckled on the top of the synchronous disk 11, and the inner ring diameter of the clamping block 18 is larger than the outer ring diameter of the synchronous disk 11. A smooth block 19 is fixedly installed on the bottom of the clamping disk 13. The smooth block 19 is fitted into the smooth groove 12. There is a gap between the clamping block 18 and the synchronous disk 11. The smooth block 19 and the smooth groove 12 are connected by a damping slider, leaving space for subsequent horizontal vibration. The structure is compact and the design is reasonable.

[0034] The side of the clamping disk 13 is fixedly connected to multiple groups of clamping blocks 18, and the side of the clamping block 18 is provided with a threaded hole 20, and a transmission rod 21 is fixedly connected to the threaded hole 20. The end of the transmission rod 21 away from the clamping block 18 is fixedly connected to the connecting plate 22, and the bottom of the connecting plate 22 is fixedly installed with a single tooth block 33. The single tooth block 33 slides with the vibration gear 26. Through the sliding of the single tooth block 33 and the vibration gear 26, the horizontal vibration effect of the clamping disk 13 and the placement disk 16 on its top can be controlled.

[0035] A second control motor 34 is fixedly installed on the side of the connecting plate 22, and the output end of the second control motor 34 is connected to a cam 35, which slides with the bottom of the placement plate. A return spring 36 is fixedly connected to the side of the connecting plate 22, and the other end of the return spring 36 is fixed to the side of the synchronous disk 11. The structure of the return spring 36 and the damping pulley 31 can not only make the structure fit more compact, but also when horizontal vibration occurs, the return spring 36 pulls the connecting block in the opposite direction, and the damping pulley 31 pushes the smooth block 19 in the smooth groove 12, which can quickly drive the connecting plate 22 and the clamping disk 13 back to their initial positions.

[0036] A connecting piece 30 is fixedly connected to the side of the synchronization disk 11, and the connecting piece 30 is rotatably connected to the second connecting rod 29. A plurality of damping pulleys 31 are fixedly installed on the side of the smooth groove 12, and a compression spring 32 is fixedly connected to the side of the damping pulley 31. The other end of the compression spring 32 is fixedly connected to the side of the smooth groove 12. The damping pulley 31 is fit-fitted to the side of the smooth block 19. The structural design of the damping pulley 31 and the auxiliary reset spring 36 perform the reset operation, and the structure is simple and practical.

[0037] When used specifically: first, open the door on the side of the simulation warehouse 4, place the carton 17 to be tested on the top of the placement plate, and then start the active motor 6, which drives the rotating shaft 7 to rotate. The rotating shaft 7 also drives the rotating disk 8 on the side and the active bevel gear 23 on the top to rotate. When the rotating disk 8 rotates, it is transmitted through the connecting rod assembly and synchronously drives the synchronous disk 11 to rotate. The synchronous disk 11 is engaged with the card plate 13. At the same time, the transmission rod 21 is simultaneously inserted into the card plate 13 and the synchronous disk 11. The synchronous disk 11 rotates with the card plate 13, and the card plate 13 is rotated by the telescopic rod 1 4 drives the placement plate 16 and the carton to be tested 17 to rotate, the active bevel gear 23 drives the driven bevel gear 27 to rotate, and at the same time the driven bevel gear 27 drives the vibration gear 26 to rotate through the synchronization rod 25. During the rotation process, the vibration gear 26 will contact the single tooth block 33 at the bottom of the connecting plate 22. The teeth of the vibration gear 26 will push the single tooth block 33 and the connecting plate 22 structure on its top to slide. The connecting plate 22 drives the clamping plate 13 and the placement plate 16 to slide through the transmission rod 21. However, the reset spring 36 pulls the connecting plate 22 in the opposite direction, and the pulley with internal resistance of the smooth groove 12 pushes The movable smooth block 19 exerts a reverse force on the clamping disc 13, which can quickly drive the connecting plate 22 and the clamping disc 13 back to the initial position. Therefore, as the vibration gear 26 rotates, the single tooth block 33 will continuously repeat the process of being pushed by the vibration gear 26 to translate and reset, achieving a horizontal axial vibration effect. In this process, the first control motor 10 and the second control motor 34 can be started. When the first control motor 10 is started, different first control motors 10 drive the first connecting rods 28 in different connecting rod assemblies to rotate different angles in the hinge seat 9. Under the transmission connection of the first connecting rod 28 and the second connecting rod 29, the inclination angles of the synchronous disk 11, the clamping disk 13 and the placement disk 16 can be controlled. When the second control motor 34 is started, the cam 35 can be driven to rotate. The cam 35 is fitted and connected with the placement disk 16 during the rotation process. The placement disk 16 slides up and down on the irregular surface of the cam 35, thereby producing an up and down vibration effect. At the same time, under the connection of the tension spring 15 and the telescopic rod 14 between the placement disk 16 and the clamping disk 13, the placement disk 16 and the clamping disk 13 have a tighter structural combination and a smoother vibration effect.
