Technical Field

[0001] The utility model relates to the field of safety airbag manufacturing, in particular to a safety airbag folding device. Background Art

[0002] An airbag is a passive safety device installed inside a car. It is mainly used to act as a buffer between the occupants and the car body by instantly inflating and popping out when a vehicle collision occurs, thereby protecting the occupants' safety and reducing the degree of injury. After manufacturing, existing airbags need to be folded. The processed airbags are folded into small pieces and installed in the car steering wheel for subsequent assembly.

[0003] The existing patent announcement number (CN221113826U) discloses an airbag folding mechanism, including a processing table, a circular frame and a movable plate, both sides of the circular frame are provided with mounting components, a plurality of through holes are opened in the middle of the top of the processing table, the movable plate is located at the bottom of the processing table, and a driving component for lifting the movable plate is provided at the bottom of the processing table. This scheme drives the movable plate to drive a plurality of limit plates to rise by the driving component, so that the plurality of limit plates are movable through the plurality of through holes respectively, and the plurality of limit plates cooperate with the circular frame to form an arched cavity, and then the airbag can be placed in the arched cavity so that it can be folded into an arch, and then the driving component drives the movable plate to drive the plurality of limit plates to descend, so that the plurality of limit plates are separated from the plurality of through holes, and then the airbag folded into an arch can be taken out; compared with the prior art, the error of the folding size of the airbag can be effectively reduced.
