Problems solved by technology
The drop test device in the prior art is to lift the packaging bag to a very high height, and drop the object to be tested from this height in a free fall manner, which requires the drop test device to reach this height , resulting in a large volume of the test device, and the height of the drop test is also limited by the height of the instrument
At the same time, the whole test is difficult to complete indoors

Embodiment Construction
[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0023] figure 1 It is a schematic diagram of the module structure of the rotating bag drop test control system. As shown in the figure, the control system includes an MCU central processing unit, an angle acquisition unit, an angular velocity acquisition unit, a serial communication unit, a drive circuit, and a host computer;
[0024] During the operation of the system, the MCU central processing unit controls the angle acquisition unit and the angular velocity acquisition unit to collect the rotation angle and linear velocity of the object to be measured in the rotating bag dropping device, and the MCU central processing unit passes the collected data through the serial port communication unit The host computer calculates and analyzes the data. When the set value is reached, the host computer sends a control command and transmits it to the...

The invention relates to a rotary falling testing system and a rotary falling testing method. The testing system comprises a rotary falling device and a control system. In a system operation process, a MCU central processing unit is used for controlling an angle acquisition unit and an angle speed acquisition unit to collect a rotary angle and a linear speed of a detected object in the rotary falling device; the MCU central processing unit is used for transmitting collected data to an upper computer by a serial port communication unit; the upper computer is used for calculating and analyzing the data; after a pre-set value is reached, the upper computer sends a control instruction and the control instruction is transmitted to the MCU central processing unit by the serial port communication unit; the MCU central processing unit is used for controlling to open a cabin door on a material cabin by a driving circuit so that objects in the cabin can accurately fall on the ground. The system is convenient to operate; falling objects can be simulated very well and the result is accurate; and meanwhile, the limitation on the height of instruments and the space environment is avoided.
Description
technical field [0001] The invention belongs to the technical field of product quality detection, and relates to a rotating bag drop test system and a test method. Background technique [0002] Some products, such as packaging bags, are subject to drop testing before leaving the factory. After the packaging bag is full, it needs to be dropped from a high place to check whether it is damaged. When performing drop detection, it usually starts from 2 meters, and the height is gradually increased. The drop test device in the prior art is to lift the packaging bag to a very high height, and drop the object to be tested from this height in a free fall manner, which requires the drop test device to reach this height , resulting in a large volume of the test device, and the height of the bag drop test is also limited by the height of the instrument. At the same time, the whole test is difficult to complete indoors. Contents of the invention [0003] In view of this, the purpos...
