With the continuous increase in global automobile production and increasingly stringent consumer demands for automotive safety standards, the production efficiency and quality control of airbags have become core concerns for major automotive component manufacturers. The airbag filter, as a crucial part of the airbag assembly, bears the heavy responsibility of filtering impurities and ensuring the airbag inflates quickly and accurately in critical moments. Therefore, improvements in its manufacturing process are urgently needed. This is not only related to product quality but also closely linked to the overall safety performance of the vehicle, directly impacting the safety of consumers' lives and property.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1 to 3This utility model provides an embodiment of an automated cutting device for producing airbag filter cores, comprising a support base plate 1, a raw material placement plate, and a support base plate 1 serving as the basic load-bearing component for the entire automated cutting device. A support frame 3 is fixedly connected to the outer side of the support base plate 1. A push mechanism support frame 3 connects the support base plate 1 to a fixed plate 4. A fixed plate 4 is fixedly connected to the outer side of the support frame 3. A spacing adjustment mechanism 7 is provided on the outer side of the fixed plate 4. A sliding plate 5 is slidably connected to the outer side of the fixed plate 4. A rapid cutting mechanism 8 is provided inside the sliding plate 5. A protective component is provided on the top of the support base plate 1. The push plate and fixed plate 4 support the adjustment mechanism, the spacing adjustment mechanism 7, and the rapid cutting mechanism of the protective ring. The cutting mechanism 8 includes a motor 801, which is externally fixedly connected to the inside of the sliding plate 5. The drive end of the motor 801 is fixedly connected to a transmission column 803, which drives the transmission column 803 to rotate. The transmission column 803 is externally slidably connected to a push plate 804. The transmission column 803 rotates at high speed under the drive of the motor 801. Its special external sliding connection structure works well with the push plate 804. The push plate 804 is externally slidably connected to a limit component. The inside of the push plate 804 is fixedly connected to a cutting blade 805. The cutting blade 805 directly acts on the components of the airbag filter core material. Its sharpness, material hardness, and blade shape directly determine the cutting effect.
[0025] The limiting assembly includes a limiting post 806, which is externally slidably connected to the inside of the push plate 804. A fixed base plate 807 is fixedly connected to the bottom of the push plate 804. The limiting post 806 is used to limit the movement trajectory of the push plate 804. The fixed base plate 807 is externally fixedly connected to the outside of the sliding plate 5. The fixed base plate 807 is used to fix the limiting post 806. A pressure spring 802 is sleeved on the outside of the limiting post 806 and the top of the push plate 804. The pressure spring 802 stores force and releases it intermittently to quickly push the cutting tool 805. The top of the pressure spring 802 is fixedly connected to the bottom of the sliding plate 5. The fixed block sliding plate 5 is used to slide outside the push plate fixed plate 4.
[0026] Reference Figure 1 , Figure 2 and Figure 4The spacing adjustment mechanism 7 includes a cylinder 701, which is externally fixedly connected to the outside of a fixed plate 4. A connecting push block 702 is fixedly connected to the driving end of the fixed plate 4. The fixed column cylinder 701 is used to push the fixed plate 4 and the connecting push block 702. A sliding plate 704 is fixedly connected inside the connecting push block 702. The fixed plate 4 and the connecting push block 702 are used to transmit the thrust of the fixed column cylinder 701 to the sliding plate 704. The sliding plate 704 is externally slidably connected to the outside of the fixed plate 4. A sliding column 703 is also connected to the internal groove of the sliding plate 704. The sliding plate 704 is used to provide a groove for the sliding column 703. The sliding column 703 is externally fixedly connected to the outside of a sliding plate 5. The external sliding connection of 5 is to the outside of the fixed plate 4. The fixed block sliding plate 5 is used to provide a stable installation environment for the transmission column 803. The protective component includes the workbench 2. The bottom of the workbench 2 is fixedly connected to the top of the support base plate 1. The top of the workbench 2 is fixedly connected to the fixing strip 9. The probe of the second support block fixing strip 9 limits the airbag filter material by physical blocking. The top of the workbench 2 is fixedly connected to the flexible pad 6. The outside of the flexible pad 6 is fixedly connected to the outside of the fixing strip 9. The second support block fixing strip 9 is used to limit the airbag filter material by physical blocking. When the cutting tool 805 falls to cut the material, the flexible pad 6 can absorb part of the impact force and protect the workbench 2 from the impact damage of the tool.
[0027] Working principle: The rolled airbag filter material is placed on the workbench 2. The flexible pad 6 acts as a buffer and protects the workbench 2. The fixing strip 9 can limit the material to a certain extent, so that it is not easy to move during the cutting process.
[0028] When it is necessary to adjust the spacing between the cutting blades 805 to accommodate the cutting requirements of filter cores of different sizes, the spacing adjustment mechanism 7 is activated. The cylinder 701 pushes the connecting push block 702 to move. The connecting push block 702 drives the sliding plate 2 704 to slide on the slide bar of the fixed plate 4. The sliding plate 2 704 drives the sliding column 703 in the internal groove to slide together. The sliding plate 1 5 also moves together on the slide bar outside the fixed plate 4, thereby realizing the spacing adjustment of the fast cutting mechanism 8 fixed inside the sliding plate 1 5 to meet the cutting requirements of filter cores of different widths.
[0029] When preparing for cutting, the motor 801 drives the transmission column 803 to rotate. During the rotation of the transmission column 803, due to the sliding connection between its external specific groove and the push plate 804, the push plate 804 is restricted by the limiting component and can move up and down along the limiting column 806. When the transmission column 803 drives the push plate 804 to move downward, the cutting tool 805 quickly cuts the filter material on the worktable 2. After completing one cut, the transmission column 803 drives the push plate 804 to move upward, and the pressure spring 802 returns to its deformation, providing assistance for the next cut. This cycle repeats to achieve fast and continuous cutting action and efficiently produce airbag filter elements that meet the size requirements.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
