Whether the product packaging can effectively protect the product from being transported by automobile, sea, air, etc. It will be directly related to the safety of the product and the transportation cost and handling cost of the enterprise. Therefore, domestic and foreign testing agencies in related fields have published test methods for packaging safety protection and testing, and understand packaging performance through scientific test data. , to improve in time for vulnerable parts or parts that do not meet the testing standards.

At present, it is generally done by using a drop test machine, which is mainly used to simulate the free fall that the product may be subjected to during handling, and to examine the product's ability to resist accidental impact. Among the drop test machines, the zero drop test machine is one of the types of drop test machines. It is characterized in that it can perform drop tests from a zero height range and is suitable for large-scale package drop tests.

Fig. 1 is a perspective view of the utility model.

In the figure, impact base plate 13, positioning bracket 15, first guide rod 8, second guide rod 10, driving screw 9, lift control box 5, drop fixing box 6, support arm 4, supporting plate 11, first adjustable Clamp rod 1, second adjustable clamp rod 2, guardrail 7, groove 12, test object 14.

detailed description

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

Referring to Fig. 1, a zero-drop testing machine includes an impact base plate 13, a positioning bracket 15 vertically fixed on the impact base plate 13, and a first guide rod perpendicular to the impact base plate 13 is fixedly arranged on the positioning bracket 15 8 and the second guide rod 10, a drive screw 9 is arranged in parallel between the first guide rod 8 and the second guide rod 10, and the first guide rod 8, the second guide rod 10 and the drive screw 9 are respectively From top to bottom, a lifting control box 5 and a drop fixing box 6 are arranged sequentially, one side of the lifting control box 5 is fixedly provided with a support arm 4, and one side of the drop fixing box 6 is fixedly provided with a supporting plate 11, The drop fixing box 6 is provided with a cylinder, and the cylinder is fixedly connected with the supporting plate 11 , and the lifting control box 5 is provided with a motor connected with the driving screw 9 in transmission.

The support arm 4 is respectively provided with a first adjustable clamp rod 1 and a second adjustable clamp rod 2 .

The shape of the supporting plate 11 is E-shaped.

The impact bottom plate 13 is provided with an E-shaped groove 12 corresponding to the supporting plate 11 .

Guardrails 7 are provided on both sides of the impact bottom plate 13 .

During the test, according to the needs of the test, the height of the supporting plate 11 is adjusted to the required height, which can be very small and set close to zero. Place the test object 14 on the pallet 11, lift the pallet 11 to the required drop height, fix the test product 14 by the first adjustable clamp rod 1 and the second adjustable clamp rod 2, and then drop the fixed box 6 Adjust the height to a suitable position, start the cylinder in the drop fixing box 6, and the cylinder generates a downward force to accelerate the pallet 11 to slide downward freely. Because an external power is applied, the pallet 11 slides downward The speed is faster than the test object 14 falling downwards by its own gravity. At this time, the supporting plate 11 and the test product 14 will separate, and the test product 14 will fall. The supporting plate 11 reaches the E-shaped groove 12 of the impact bottom plate, and the test object 14 reaches the impact bottom plate in a free-fall manner after a certain period of time, and the drop test is completed. The supporting plate 11 also becomes the state of free fall after being subjected to a sudden downward force, therefore, it is ensured that the supporting plate 11 will not be in contact with the dropped test object 14, thereby not affecting the accuracy of the test structure.

The above embodiments only show and describe the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
